Manufacturer of leading tube processing machines invites U.S. partners to technical training and information-sharing workshops

Advanced tube processing machines that deliver the latest tube solutions are extremely complex. To grasp all of their technological and value-added features and functions while also providing optimal support, even the most experienced service professionals need to attend training workshops regularly. For transfluid, a high-tech machine manufacturer whose products are in high demand worldwide, this combination of regular training workshops and practical knowledge building is a fundamental principle. That is why the company recently invited the employees of its sales and service partners in the U.S. – Advanced Fabricating Machinery and Modern Machinery – to its German headquarters in North Rhine-Westphalia.

transfluid also presents flexible tube machining solutions with process networking possibilities at the Hanover trade fair

The increasingly powerful digital connection for tube machining processes is a tailored driver of technical progress within the industry. For hydraulics in particular, solutions are required, which ensure safe tube machining, as well as automated processes where required.
Powerful automation is even possible with very low unit quantities, for example with the technical machining of hydraulic connection elements. As such, transfluid - with its axial forming machines of type REB and tool-independent rolling forming with systems of type SRM - offers the solution for hose connections or DKOL connections directly on the tube, for example. These enable sharp-edged contours for sealing elements and optimum surfaces. The production of flanges between 20° and 90° with short clamping lengths can be realised with transfluid forming machines of type UMR - for optimum sealing surfaces and in a single process.

2017-05-05 095058

Digitally connected with design and measuring systems
“In the future, greater flexibility will be required for even better processes. I think for example of the online connection between design and our bending software t project. And also of systems that measure both at the building and the finished tube. Such a system must of course be simple to use. That is sure to deliver greater bending freedom”; Stefanie Flaeper, managing director of transfluid, outlines the demands and further developments.

More effective bending – 42 mm and more
This was the objective of the engineers at transfluid, when they developed their mandrel bending machine of type t bend DB 40220-3A-CNC. With this machine, it is possible to bend thick and thin-walled tubes with diameters in particular from 40 mm and up to 220 mm. The stable design ensures a long service life and simple, rapid tool changes enable diverse applications and improved efficiency

2017-05-05 095116

Collision-free right/left bending
The right/left-bending machine t bend DB 642 CNC R/L VE with rotating head delivers a strong performance when producing extremely demanding geometries, even when structural obstacles are present. With this servo-electrically driven concept for tube diameters up to 42 mm, each bending head has two tool levels as standard. Process assurance is provided by the complete visualisation of production processes on the freely programmable CNC touch panel control

Mobile and high-performing in application on site
transfluid offers flexibility together with simple and effective technology for bending directly on site in the building, with its latest generation of the mobile bending machine t bend MB 642. With it, hydraulic lines can be laid at the installation site. As additional equipment, you can also chose from the internal and external deburrer, a saw, an assembly device for all conventional connection systems (flanging and cutting ring fittings), as well as metal circular saws.

transfluid simplifies complex tube processing with an automatic tool change system

Continually faster and more adaptable: Bending of tubes with diameters of up to 127 mm is growing continually more demanding, while the subsequent costs are to approximate zero. "It isn't only about implementing technical efficiency in processes or machines anymore," says Stefanie Flaeper, managing director at transfluid. "Most of all, the increased demands to new products must be implemented here. No matter the time efficiency and precision, the solution should, of course, be controllable." The specialists from Germany have developed their tube bending machine t bend DB 40120-CNC-VE for this. It permits bending radii of 1 x D at very thin wall thicknesses for such tubes.

More effective with transfluid sequence control
In the scope of a current project, the setup of this special bending system has been implemented fully electrically. All movement axes are optimally synchronised by the special transfluid sequence control or can be programmed controlled against each other. Additionally, it is possible to easily optimise the process via this sequence control, which effectively improves product-specific cycle times.

Another strong point is simple operation. All parameters can be taken from the CAD. Necessary form clamps are integrated in the automatic sequence. The transfluid engineers have implemented reduction of the follow-up costs by an automatic clamp die change system. The time frame for tool change is comparable to that of a radii changer.

Changing the clam dies up to eight times
The new DB 40120-CNC-VE has two tool levels. It is able to change the clamp dies eight times, so that each tube can be bent even in highly complex geometries. This form of tool equipment is particularly efficient, reducing follow-up costs to a minimum. "In particular because the diameters are relatively similar and radii are very tight with 1 x D, only the bending geometries really change in new products. This means that only new clamp dies need to be used," explains Stefanie Flaeper. To implement the tight radii at a relatively thin wall thickness, the new tube bending machine has an additional boosting device that can controlledly support even the last bend at short rest lengths.

Reliably brought into form

Newly developed axial tube forming machine REB 645 by transfluid with automatic tool detection
Workpieces of a special end form geometry are in demand again and again. Whether for the initial production or repeated precision: Ensuring exact parameters is necessary for an efficient implementation. Thus, the solution finders of transfluid have developed a solution with automatic tool detection for tube forming. Hence, the new axial tube forming machine form REB 645 allows for tube end forming with fast tool changes for complex geometries and extreme degrees of forming.

2017-01-30 082350

From the barcode to the better result
The starting point is a barcode scanning system. Using this system, the operation data of a tube with individual barcode can be easily read – for an end forming for example. For this purpose, all tools of the machine, which is equipped with 6 forming stations, have sensors (RFID). This ensures that the right programme and the appropriate tools are available. If the automatic inspection unit detects a wrong tool, the operating panel with data memory displays this information immediately. Here, the identification for the correct tool for the change is indicated as well. Using the convenient quick-connecting system of the transfluid solution with fork for fixing and locking bolt for securing the mount, the machine operator can directly change the tool and precisely perform the tube end forming afterwards.

Certainly flexible and reliable
The REB 645 allows the axial forming of tubes with diameters from 6 to 45 mm. By means of a servomotor, the tool sequence is positioned horizontally and vertically. In addition, rolling stations for specific forming processes can be integrated. Upon request, the machine can be equipped with electric or hydraulic numeric drives. In case of extremely short cycle times, these forming procedures can also be carried out gradually in transfer systems. With the new tube forming machine, transfluid ensures even more reliable processes and more flexibility for individual requirements.

Coordinated transfluid technology improves process safety

Many paths not only lead to Rome, but also to the desired product result. Of course, the production plants and systems are very important for safe processes in tube processing. The solution finders of transfluid use their knowledge in development of the properly coordinated tube bending and tube forming machines for this.

2016-10-28 095017

© transfluid Caption: At the beginning of the process, transfluid ensures quick sequences by chipless clean cutting. Forming comes first, followed by bending.

The high-tech machine constructors produce additional added value also by precisely coordinated production of tools, as Stefanie Flaeper, managing director at transfluid, explains: "We develop tool technologies that match our machines. Of course, they correspond to the complete requirements that our customer has to his specific product or any new one." This development always must be viewed in connection with a machine accordingly. "Of course, we share our individually developed know-how with our customers," says Flaeper. "They participate and profit from this in different ways."

New paths for better production

Effective new design of individual process steps often secures economically more efficient production. For example, a transfluid project required a production cell for production of special short tube parts. A classical process would have been defined initially by cutting the tubes by metal circular saw, unilateral forming of the hose connection, bending, cutting off the oversize and forming the second tube end. "We don't stop our considerations at the proper shape," Stefanie Flaeper emphasises. "The path to the result must be just right as well. That includes making it more economically efficient, process-safe and easier for our customers."

2016-10-28 095042

© transfluid Caption: The individually adjusted transfluid production cell from the portfolio range 't motion' ensures the matching result quickly and effectively.

Chipless to the faster cycle

Thus, the better system solution after completing the transfluid project is that the material from the coil is initially shortened to the desired lengths in the chipless orbital cutting procedure. The clean cut permits immediate further processing and paves the way for faster cycle times. After cutting, both sides will be reshaped. transfluid generally puts this step before bending. In this case, it avoids having to cut off the overlengths and permits simpler handling, finally, the desired tube parts are bent as well. "It always depends on the process, good interaction of technologies and the possibility of an effective cooperative partnership," Stefanie Flaeper finally summarises.

transfluid large tube bending machines with fast tool changes permit narrow radii even in CuNiFe and stainless steel tubes.

Capacities are planned with increasing efficiency in international ship construction and the offshore area, and present resources are used to higher capacity to improve processes. Therefore, the industry relies more than ever on time- and cost-saving bending machines for large tube diameters in tube processing. Advanced tube bending technologies are proving their worth as an efficient alternative for welding of large tubes. High-tech company transfluid is developing this solution for tubes in the scope of its portfolio range 't bend'. The bending machines permit high-performance processing of tubes with diameters of up to 325 mm.

2016-10-10 205445

Stefanie Flaeper, managing director at transfluid, explains: "Our bending technology considerably reduces the production costs while creating a time benefit of up to 60 %. This is an unbeatable benefit on the international markets." The trend is towards flanges being welded to the straight tube before bending, with the effect of internal linking to the corresponding CAD programs. The isometrics can be directly processed in the transfluid bending software 't project' this way. "We offer enormous flexibility that, together with the extremely short tool change times of less than 20 minutes, permits a clear efficiency increase in tube production," says Stefanie Flaeper.

Mobile use on board
The mobile tablet version 't project Draft' increases flexibility with special requirements. If tube data do not come from the CAD, they can be manually entered in the software. This may be the case if tubes are already present and are measured accordingly. Since this is not always done in-house, but may take place directly on the ships, the tablet version increases flexibility. This software permits isometric measurement and input of tubes. Then the data are sent to the production department directly by email, where production can already start while further tube geometries are recorded on the ship.

End forms and space benefits
The option of end forming processes, e.g. for forming on flanges, is one strength. The transfluid bending technologies permit optimised processing of large tubes and tubes with small diameters. Narrow radii are possible even in CuNiFe and stainless steel pipes, permitting an additional space benefit in the ship.

Ready for the Series
Transfluid creates expanded prototyping options for new pipe forming geometries

Pipe forming technology is a complex matter – with ever smaller tolerances for advanced new projects from the different industries. These companies with their fresh ideas are, of course united by the wish of transferring the new product to serial production safely and reliably at once after development. This also applies to high-tech machine constructor Transfluid, which uses its pipe processing technologies for research in its internal prototyping department. This is not only about sampling of its own new developments, e.g. in the area of tool technology. Companies without machinery of their own can have their pilot series analysed and precisely improved at Transfluid.

2016-08-01 073829

Different pipe processing technology, such as this continuous SRM type forming machine, are available in the prototyping department for the smallest clamping lengths at optimally controlled forming results.

"Support in this area is in higher demand than expected. Therefore, we have expanded our research and prototyping department once again just recently," says Stefanie Flaeper, managing director at transfluid. "We can perform diverse tests on components and tools with pipe diameters up to 65 mm here." A CNC-controlled type SRM rolling forming machine and two axial forming machines are used for this with a forming power of up to 25 tons. The entire process chain can be implemented with an additional CNC-controlled pipe bending machine and an orbital pipe separation system - to ensure that requirements, e.g. regarding burr formation, can be met.

Tests and documentation for light-weight construction components and high-strength materials as well
For specific customer projects, the experts in the department are testing new forming geometries and tool concepts for serial maturity and quality. The Transfluid team relies, among others, on a tactile and visual measuring system for components and tools. The interim results up to the certain result are documented reliably.

The Transfluid experts have special experience as a technology leader and initial developer of incremental pipe forming, which permits partial rotation-symmetrical forming of pipes made of high- and very-high-strength materials. In particular review and assessment with light-weight components and high-strength materials is possible as well. Depending on geometry, this can even be done tool-independently. Thus, the company can offer the pilot series or prototype production particularly cost-optimised.

transfluid develops a new general of combination machines for axial and rolling pipe forming

The technical evolution is mostly targeted at designing new solutions at the state of the art to simplify work and improve results. The engineers at transfluid followed this principle as well, developing a new generation of combination machines that effectively combine the benefits of the axial and rolling forming.

2016-08-01 072901

The new generation of transfluid combination machines combines the benefits of axial and rolling pipe forming even more effectively.

The plants are particularly characterised by their diversity in forming of parts, as Stefanie Flaeper, managing director at transfluid, explains: "Geometries in pipe end machining can be formed directly on the pipe, replacing usually complicated and expensive turned parts. No soldering or welding is needed: The pipe and its end form are virtually from a single cast."

Flexibly processes
The benefits of this kind of process are clear: Implementation of the combination can be specified by the user directly, or based on the forming geometry. "Usually, up to 6 axial forming stages and at least one rolling unit are used. If trimming, axial and rolling forming are needed, two rolling stations may be required as well," says Stefanie Flaeper. "We also call this 'powered axes'."

Single-drive axes for a more compact setup
Pipe machining may include a simple trim or deburring at the pipe end after forming. Because this is not a demanding process-technical challenge, it is sensible to use compact units for this. transfluid has made it possible to equip all axial forming machines and all combination machines with one or several single-drive axes. These axes have a servo-electrical drive and can be used for the forming stages in each of the holders. This makes the system very compact and particularly flexible. Because the transfluid combination machines have electrical drives, all forming tools are positioned very precisely and the machines can be used much more diversely.

transfluid develops flexible production cells for smart tube processing Live from the tube Düsseldorf

Precisely produced tubes help make energy and water flow or medical devices support the life-saving work of doctors. Robust, short hose connections for automotive construction or long, multiply-processed tubes, e.g. used as air conditioning lines, also need many different requirements to the proper production solution. Depending on industry and application area, they need to be specifically formed, bent, and diversely processed, of course. The networked 't motion' automation systems by transfluid create combined options for the large series operation for this. This not only leads to capacities but also ensures the process safety that parts are always produced at the same good quality.

"We use our sophisticated technology concepts for tube bending, separation, cleaning and tube forming for the automation systems, supplementing them, e.g., with loading systems, weld seam control or complete handling," says Stefanie Flaeper, managing director at transfluid. "With the easy-to-operate production cell coordinated in this manner, production can start right away. The principle clearly is one of Plug and Produce. Our customers place value on this. They trust in our decades of experience and our progressive high-tech solutions."

2016-04-05 095958

The complete production cells are specifically coordinated with the requirements, including generation of the layout to achieve the perfect material flow.

Complete systems for complex challenges

The specialists at transfluid integrate expansions such as marking facilities, seam detection devices, printers, tightness tests or visual, contact-free camera systems for inspecting geometries or surfaces, brazing and welding units and auto-frettage as optional components on request. Effective loading systems, storage systems, supply of the workpieces or complete handling by robot or in linear systems can be added as well. "We coordinate the solution specifically with the customer's requirements, including generation of the layout to achieve optimised material flow and best utilisation," explains Stefanie Flaeper.

What is better? Highly flexible linear systems or robots?

Selection of handling of course also focuses on highest possible efficiency. The devices used strongly depend on the parts to be produced. Stefanie Flaeper presents a general principle: "Everything that can be done to the tube in the straight condition considerably reduces the handling effort. From the bending machine onwards, the robot usually takes over. Linear handling can often be faster, more cost-efficient and easier to reach." For smooth production flow, transfluid develops its production systems to permit loading of isometric data online from a CAD system and to avoid elaborate programming of robots. 

The matching component supply

Coming off of the starting block well and maintaining the head start will bring a runner in first, too. Therefore, the systems for loading and separation already contribute to the high performance of 't motion'. Components (nuts, flanges, screws) are supplied from splitter magazines or rotation separators with presence and position checks. Additionally, supplies from the coil or by loading table, by belt, stage, plate, chain or vibration conveyor are available to match the overall system. In strong connection with its tube forming, separating and tube bending technologies, transfluid thus ensures high-performance linked automation systems linked in a result-oriented manner that offer individual solutions for many different pipe productions.

Innovative developments by transfluid make processing of tubing more cost-effective

transfluid has again pushed forward the boundaries of technology in the form of its automatic machine for the shaping of tubing. Thanks to imaginative developments in engineering techniques it is now possible for the first time to create non-tool-based, CNC-controlled profiles. In addition, the engineers at transfluid have also provided the option of working with tubing chuck sizes of less than 0.5 x D and to cut and shape these - all in one single work process.

The latest brainchild in the field of continuous shaping of tubing generated by the team based in Schmallenberg in Westphalia in Germany involves the use of an 'SRM'-type machine to expand tubing (T-pieces) with the help of very simple tools. This continuous shaping machine can produce items in both horizontal and vertical designs to meet the needs of individual applications and requirements. All functions are operated servo-electrically and can also be CNC-controlled as necessary.

tpeice 1

Increased demand for flexible production processes

Stefanie Flaeper, CEO of transfluid, has this to say about the new system: "Our 'SRM' machine for continuous shaping of tubing can be modified and is thus highly flexible irrespective of whether it is employed for non-tool-based shaping or, as in this instance, for the expansion of tubing. And it is the flexibility that is an important feature of our development concepts that our customers find particularly attractive."

The company is also responsible for innovations with regard to axial tube forming, specifically in connection with tool technology, and these result in improved quality and output. "Multiple shaping operations of a tube end can be undertaken with the help of our pneumatically opening segment tool," explains Stefanie Flaeper. transfluid has equipped these tools with a pneumatic system that controls and opens elements and can verify their positioning. "With our special tools for tube forming, we have managed to ensure that the external surfaces of tubing remain untouched during the shaping processes so that there are no scratches or friction deposits on surfaces. This is because our tools open and close as appropriate to the required position during shaping."

tpeice 2

Cost-efficient tool systems

By combining flexibility with the frequently required lightweight construction concepts, especially those of the automotive industry, transfluid has built tool systems with which it is possible to prepare tubing in specific wall thicknesses. This is a particularly efficient solution because it means that thinner tubing can be employed and the wall thicknesses can be created that are required for further processing for use in the various applications.

But in the case of transfluid, flexibility also means in this context that shaping can be first undertaken before the tubing is bent, an approach that relies largely on the availability of the suitable tube bending technology. And this technique also saves money as it is thus no longer necessary to use expensive spanning devices for forming while outgoings for internal logistics operations, handling and loading are reduced. Not only this, but transfluid is also able to provide tube bending machines with an automatic clamp set changer, something that is of additional benefit in situations in which multilevel tools are being employed.

transfluid intends to systematically continue with its current developments in tubing shaping and bending technology with the aim of making tube processing even more efficient.

transfluid is ensuring bending freedom with its new ‘t bend’ mandrel bending machine
Adaptability and flexibility have always been a successful characteristic in evolution. This is just as true in nature as it is for advanced technology for bending tubes. The mechanical engineering company transfluid used this principle for the new, fully automatic ‘t bend’ mandrel bending machine DB 622-CNC. The current system development for tube processing has no corners or edges and is completely encased in a round, new design. “The compact design, with an integrated safety housing around the machine, allows operation with a separate safety apparatus”, explains Stefanie Flaeper, Managing Director at transfluid.

mandrel trans

Radii changers for form spanners and spanners
The fully automatic system can be freely programmed without specific CNC knowledge using touch panel control, allowing exact bending of round steel tubes with a diameter of 22 x 2.0 mm, of stainless steel tubes with a diameter of 22 x 1.5 mm and of square tubes with a diameter of 16 x 1.5 mm. Bending angles of up to 180° are possible. The machine has mandrel support for the precise placement of the mandrel tip. It is also fitted with a radii changer for two changes of the processing level. This also allows the processing of a tube with alternating form spanners or spanners. The maximum change height is approximately 60 mm and the radii difference between the levels is 1.5 x D.

Flexibility and safety in production
The control system works with three individual axes for bending, turning and length positioning. Once the bending data has been entered the bending programme is generated automatically and can also be manually optimised during operation. Furthermore it is possible to split one bending process into several segments in order, for example, to achieve different speeds on one arc. The speeds of the servo axes are automatically synchronised to one another in order to minimise wear and power consumption. The system has been developed and realised as a whole in accordance with the latest technical safety regulations. transfluid is thus ensuring efficient and safe tube processing.

The right tool for the best molding

In the development of molding technologies, versatility is a common challenge depending on the sector and the use of tubes. However, in the process of diversification, machine is not the crucial component in seeking the appropriate solution, rather, in particular, the tool. transfluid Maschinenbau GmbH operates on this knowledge. The machine and the process are certainly very varied given the diverse and individual demands. “So, for instance, our upsetting technology could be in demand, with the upsetting capacity of 98 kN, 147 kN or 196 kN,” says Stefanie Flaeper, managing director at transfluid. “Or our roller technology, that facilitates tooling-independent molding with only one tool. Even combination machines that display the axial and roller molding in a tube clamping are potentially necessary. 

Press image 01 web

In order to secure powerful results, it is important that the tools used during the procedure guarantee the design of every individual product. The rigorously customized tool development undertaken at our company include feasibility studies, if necessary a sample production and the prototyping for that. An entirely new department has been created to cater to the latter, where specialists inspect components and tools of up to 45 mm diameter. 

Not bending

Tool design is an especially relevant topic even for axial tube molding. Thus, for instance, insofar as the cycle time allows for that, transfluid often inserts an intermediate clamping unit in hose connections. It provides internal support for the entire geometry. The technology prevents the tubes from bending inwards at sensitive locations.

Pneumatic guard locking prevents scratches 

In the case of multiple upsets that cannot be produced in the above-mentioned manner, transfluid uses a single-tier ‘sliding split molds.’ These tools are equipped with an internally controlled pneumatic guard lock. That prevents scratches from forming on the geometry if clamping claws are opened after the molding. And the position of the sliding element is always recognized.

Prevent cold welding 

A technical feature concerns the upsetting tools that open up when the molding tier moves back and forth. In the case of longer strokes, they prevent contact between material and tool. Thus it prevents cold welding between tool and material, and the surface of the material remains undamaged. Multiple beading along with an intermediate clamping fixture can also be produced using this technology. transfluid promotes the efficiency and cost-effectiveness of its entire t form tube processing machines with the progressive development of its versatile tooling design.

Axial/rotary CNC controlled pipe forming machine offers tool-independent forming of contours

2015-09-04 145539The technical challenges of modern pipe processing are constantly increasing, driven by ever more demanding applications of high grade piping. Just one manufacturing process often does not suffice to perfectly and effectively form pipe ends to suit the requirements. This was made possible only by effective interaction between combined axial and rotary pipe forming techniques. The transfluid Maschinenbau GmbH engineers have developed a new range of their tried and tested combination machines to achieve this. In the course of this, they have set new benchmarks for technology and machine design.

Effectively forming pipes even with bends in excess of 90 degrees

Managing Director Stefanie Flaeper explains more about the improvements and novelties incorporated in transfluid’s ‘new one’: “There are actually five fundamental changes. For a start, our combination machine is now externally more compact. All the drives are electrical and CNC control enables synchronous axial and radial movements. And we have once again made significant improvements to rotary forming techniques. For the first time, these techniques now enable forming of contours virtually independent of the tool. Our machines are furthermore also now CNC controlled and it is possible to very effectively form pipes with bends in excess of 90°.”

Increased options and chipless cutting methods

These new features of the combination machines now open up additional pipe forming options. The swaging unit can accommodate, for instance, an intermediate chuck, despite the electrical drive. A wide variety of tools may be used for various rotary forming tasks and the machines can also cut chipless – from the inside out and vice versa. Newly introduced CNC technology – as with the transfluid stand-alone rotary forming machines – for the first time also allows contour forming irrespective the tool. With their new combination machine, our South-Westphalian machine builders are now in a position to offer their customers the perfect solution for their pipes and the challenges of a dynamic market.

The manufacturing system from transfluid creates extremely short straight lengths after bending and forming

Is speed all that matters when it comes to production? Of course not! Especially for connections which must stand up to highly dynamic loads, quality has an important role to play. Tube connections used in automobile manufacturing must be robust, durable, clean, and demonstrate longterm leak-tightness. transfluid Maschinenbau GmbH has now developed an automation system for the t motion part of its portfolio which ensures the rapid and highly precise manufacturing of short elbow tubing sections. These special connections are used in car radiators and air conditioning. 

2015-07-22 090307

2015-07-22 090242Chipless cutting and precise rolling

The special transfluid manufacturing cell enables the coil to be handled directly. In the first manufacturing stage, the tubing (in a diameter range from 8 to 22 millimetres) is unwound, aligned, and cut. The orbital chipless cutting of the tubes can be performed up to a minimum length of 34 millimetres. Cleaning cutting is the key for enabling the subsequent processing steps to proceed immediately, as it excludes the possibility of contamination, which could endanger subsequent system use. 

After the cutting process, the tube ends - where the hose is connected - are compressed in a transfer line. Then a subsequent component of the line rolls and polishes the surface. This rolling technology from transfluid allows for short clamping lengths and the forming of practically any geometry.

Press image 01 WebReliable bending after tube forming 

After the axial and rotary end forming process, the t motion manufacturing cell automatically bends 80% of the parts by 40 to 120 degrees. The particular benefit of the process as a whole is primarily that the extremely short parts must be formed and then bent on both sides, which means there are practically no straight sections. "The challenge during development was quite clearly combining the high quality requirements with a time-efficient manufacturing process", says Stefanie Flaeper, Managing Director of transfluid. "In realising this system, our team has ensured that deformations of the tubes is ruled out throughout the process, and that the surface and any previous tube forming operations are preserved throughout the entire process." A cycle time of 6 seconds makes this high-quality production method an economical solution, especially for short parts.

Rolling tube forming also masters demanding challenges efficiently

The demands for tube processing are increasing. Geometry is becoming increasingly complex and materials are becoming ever stronger in connection with progressively light design. At the same time there are louder and louder calls for efficiency across all sectors. Rolling tube forming by Transfluid offers a solution – this is a process that opens up special opportunities for forming and reduces the use of tools to a minimum. Rolling technology always displays its particular strengths most clearly if forming is to be carried out on tubes that have already been axially preformed, if sharp edged contours need to be created for sealing elements or if perfect surfaces are required.

2015-06-19 094351

The tube forming machine t form SRM 622 by Transfluid allows the creation of almost freely formed geometries.  

One rolling head, various processes
For the tool-independent tube forming and for the creation of almost freely formed geometries all t form bead rolling machines by these specialists for tube processing machines have a servo-electric drive and an easily operated CNC control system if required. This allows the functions of different axes to be moved in an overlapping fashion. As all the setting parameters are stored there are no complex adjustments and this saves valuable time. The forming process is possible both from outside to inside and from inside to outside. Further advantage of rolling tube forming: even completely different geometries can be formed with a single tool, a clamping jaw and the rolling head. Tool wear is almost totally ruled out in a rolling process. The lubricants that are necessary in the forming process can also be reduced to a minimum.

2015-06-19 094410

High-strength materials and forming with flanges
If very demanding forming is necessary on high-strength materials then a closed rolling head is used. The forming rollers are completely supported within this. The forming of highly complex geometries without space in the axial direction is carried out using three rollers that are included in an open structure. This means that the roller geometry can be carried out directly on a tube/flange connection. It is also possible to roll threads or add edge designs with the same roller head and the corresponding rollers, with or without forming, depending on requirements. Trimming of already bent components can also be realised by rolling tube forming without cutting and almost without burrs.

2015-06-19 094427

From soldering part to compressed part – fit for a sealing ring with a mechanically fixed flange.

Forming and separating
If complex geometries need to be formed almost without clamping length then a roller head takes over this role, allowing the rolling or separating process across two rollers. One roller is positioned as support on the inside or outside of the tube while the counter roller delivers the form. This kind of inner support or forming roller can be used from an internal tube diameter of 12 mm, whereby very different tool pairings can be used. For example this makes it possible to form and separate simultaneously. Another advantage of this technology: the excellent surface quality that is created by the forming. It is usually possible to do without a cost-intensive form clamping piece on tubes that have already been bent. This is because of the extremely low loads that are transferred to the tube during the rolling process.  

If the rolling tube forming reaches its limits for specific forming processes then it is of course also possible to use pre-compressed tubes in the rolling process – or the rolling machine can be combined directly with a compressing machine. Transfluid is also offering a solution to this challenge with its combination machines, making even extreme forming reliable and safe.

Experts meet at the transfluid Innovation days for the tenth time

Progress thrives on the exchange of knowledge. This is also the conviction of transfluid Maschinenbau GmbH and it cannot be described more aptly than by the Albert Einstein quote above. With its Innovation days the company has been offering the pipe processing industry a platform for more than ten years already, with the objective of developing new perspectives as seen from the different points of view. Numerous experts once again gathered at Hotel Rimberg in the Sauerland on the occasion of this anniversary, for two days of open discussions and exchange of ideas.

Press image 02 web

“Deviating from the beaten track to share our know-how with the objective of redefining standards is quite natural to us,” says Stefanie Flaeper, Managing Director of transfluid. “The fact that our knowledge platform has by now firmly established itself, with the interest increasing by the year, demonstrates to us that the need for transparency is strong, particularly in medium-sized businesses.” The Schmallenberg Innovation days offer special added value: Together with other renowned companies transfluid, as the initiator and host, is presenting practical pipe processing technology and its potentials in the form of contributions and technical discussions. The focus this time was on “Process optimisation in piece and batch production”.

Valuable catalysts and in-depth exchange

The “Complete Piping Solutions” presentation by Parker Hannifin GmbH focussed on global pipe processing options for pipe diameters up to 220 mm in shipbuilding, offshore and hydraulics – including cutting to length, bending, fitting of connecting systems and measurement of components.

Voss Fluid GmbH presented a contribution on “Screwed and other connection systems in Hydraulics”, focussing on cutting ring pre-assembly units equipped with pressure/path controlled process monitoring and automatic tool recognition in particular. This may be used to check cutting ring pre-assembly. The company Metronor Messsysteme discussed special feeler pins including a wireless optical receiver station, allowing working unobstructed on large workpieces or working in confined spaces. This solution is ready to operate immediately and convenient to re-position – useful, for instance, to measure existing piping in ships and to transmit the data to the pipe manufacturing department or to copy. Virtual lines may also be measured in free space and two connections may, for example, be connected in this way.

By the motto “Still forming or already bending?” the transfluid presentation discussed process optimisation in pipe manufacturing and explained that forming should always take place before bending in the process chain, to avoid costly handling systems or the complexity of reworking. The new pipe bending software “t project” was also introduced and examples demonstrated how this may be deployed to reduce processing time, set-up time and machine time, streamlining processes and also generating comprehensive documentation.

A plant walkabout offered the participants additional insights into practical pipe processing. transfluid Managing Director Gerd Nöker emphasised on this occasion that progress was driven by sharing of knowledge, but especially also by customer-oriented development. This is because sustainable solutions are required to satisfy the increasing demands made by many different sectors in industry. To sum up 10 years of Innovation days: We always stand at the beginning, with an exciting future beckoning. transfluid is looking forward already to the next get-together.

A good network for precise pipe production 

New transfluid software ‘t project’ ensures safe processes and a wide range of geometrics

It is no longer possible to imagine life and work without a computer and it is primarily the right software that makes computers so valuable for daily use. Pipe production also requires systems that allow safe bending of the pipes and a monitoring of the processes. CAD systems are usually used for the designs. Pipe isometrics are usually already determined in the design. These then need to be transferred to production with as few errors as possible. An optimum bending result is achieved by taking material-specific values into account. Of course manufacturers of pipe systems wish to and must document this. Other important factors are the repeat accuracy and the variety of different isometrics. This naturally overtaxes manual administration and that is why the use of powerful software is so important. 

Press image 02 print

The software ‘t project’ can realise and document pipe processing in a secure manner.

Beyond pipe bending there is often also a need for different extension modules in order to document complete processes. The ‘t project’ software also allows the administration of process data for forming technology. Corresponding ‘nesting’ software is available for cut optimisation in the integration of separation lines.  

Powerful software ‘t project’ 

transfluid Maschinenbau GmbH has developed a specialist software called ‘t project’ for the challenges of fast, reliable pipe processing. It has a user-friendly structure and offers intuitive possible uses without intensive training. The software is based on the Windows operating system, which is always updated in accordance with the current version standard. 

Three versions of the transfluid software are available for the different requirements within pipe processing as single workplace or network versions. For reasons of sustainable production and data protection, this solution finder from South-Westphalia has ensured that ‘t project’ is connected centrally to the internal company security system via networks. 

Suitable versions on site 

The version ‘t project Basic’ converts isometrics into bending data that the pipe-bending machine can utilise directly. Correction values and overbending values are calculated automatically. The software calculates the sawing length in accordance with isometrics and material-specific data. In order to be able to carry out a simple, manual check on the bent part, the operator is provided with a measurement of the diagonal from the beginning to the end of the pipe. ‘Iges’ and ‘PCF’ software are some of the available interfaces. These interfaces are used to achieve the connection to CAD, measurement machines and/or Office programmes. If the pipes are not drawn in CAD then the input of the geometry into the software is possible absolutely, relatively or via bending data. It then converts the data into the relevant bending data. The data can also be displayed and, for example, made available to the design department.

The version ‘t project Professional’ offers the same basic configuration as the basic version. It can also carry out a collision test to determine whether the pipe will collide with the machine or the machine environment. In the event of collision, the software will propose solutions so that the workpiece may be able to be bent with slight modifications. All the dimensions of the machine that are relevan

transfluid bending machines also allow the processing of pipes that already have flanges or reforming. The software is capable of calculating the position of the flange and controlling the machine accordingly. Excess lengths for reforming can also be taken into account and calculated automatically.

For portable use

The mobile tablet version ‘t project Draft’ offers more freedom for special challenges. If pipe data is not coming from the CAD, then they can also be entered manually into the software. This can be the case if piping is also in place and can be measured accordingly. Because this doesn’t always take place in you own home but can also be on ships or construction site, the tablet version is there to give you more flexibility. This software makes it possible to measure and enter pipes isometrically. The data is also sent directly to the production department by e-mail, where production can start right away while further pipe isometrics are collected at the construction site. 

The experts at transfluid are available before the software is used to advise you and ensure long-term functional security.

For challenging installation space requirements transfluid has developed special right/left bending technology 

When it comes to pipe bending, precision is everything. In order to ensure good results, the use of the right bending technology is becoming increasingly important. This is particularly true for challenging requirements such as installation space and system positioning, as they can restrict the ideal conditions needed when forming pipes. In many cases, neither a right nor a left bending machine can produce the required geometry of the pipe bends without colliding with the machine frame. Therefore, a solution with the maximum number of bending options is required. For this purpose, transfluid Maschinenbau GmbH has created effective technologies in their 't bend' machine category, offering two effective right/left bending concepts for different pipe diameters. In the development of these bending machines, the focus was on the optimum utilization of the systems. 

Press image 01 web

The right/left pipe bending machines such as the 't bend' DB 630-CNC from transfluid offer more bending options up to 30 mm.

Bending pipes from 30 mm up to 90 mm in diameter with rotating head

In the second bending concept, transfluid has optimized the machine's effectiveness onto one rotating head. This system is also extremely dynamic for larger pipe diameters from 30 mm up to 90 mm. Larger pipe dimensions can be bent right or left more efficiently. The concept is the same for pipe diameters of less than 30 mm – all shafts are servo-electrically driven and there are two tool levels on each bending head as standard. 

Press image 02 web

The 't bend' DB 642-CNC-RL with rotating head is the dynamic solution for pipe diameters from 30 mm up to 90 mm.

Practical options for greater efficiency

To free-form large radii, both machine versions can be equipped with a corresponding system. In modern bending technology, the use of loading magazines, automatic handling systems and robot-assisted production methods are becoming an integral part. Using the greater dynamism and flexibility of transfluid technology, bending processes can be implemented smoothly and effectively in the future, despite difficult installation space requirements.

Stepping forward together:

Processing of high-strength material pipes possible for the first time

Incremental tube forming: Forward-looking cooperation of transfluid and Dortmund technical university 

The step-by-step shaping of a tube end or a tube has been made possible by the newly developed procedure for processing high-strength and ultra-high-strength materials. This revolutionises manufacturing, particularly in industrial applications where the requirements are set ever higher. And, straight tubes are formed into increasingly extreme shapes. 

2014-09-29 104007 10

Lighter and stronger products

Incremental tube shaping can be used for weight reduction purposes in the automotive industry, for example. A wide variety of products, manufactured with this new type of process, can be exposed to heavier loads and are lighter. A decisive technical advantage for the future in a fiercely competitive global market. The new development also scores with respect to resource efficiency. Significant quantities of material are saved.

The worldwide innovation of incremental tube forming has arisen from intensive cooperation between transfluid Maschinenbau GmbH and the institute for forming technologies and lightweight construction at Dortmund's technical university. The partners will be continuing their open exchange of experience and knowledge at this year's DORP. At the Dortmund colloquium for tube and profile bending [DORP] on the 1st. October 2014 Gerd Nöker, managing director of transfluid, will be giving an expert lecture to industry professionals and the scientific community on the topic of "Bending and froming: The sequence makes the difference".

Optimum preparation for subsequent processes

"Conventional forming processes are over-taxed with the majority of high-strength materials", states Gerd Nöker. "Our machine can partially shape tube made of such materials, in order to prepare them for the next process". Hydroforming for example, could be such a subsequent process. For this, a tube is pre-formed with different diameters and different wall thicknesses by means of the incremental shaping forming. Particularly important for hydroforming: There is no change in wall thickness in the locally reduced tube area.

High-strength and ultra-high-strength materials can be cold shaped.

Bending radii and free-form radii can be shaped in a continuous process with the highest degree of accuracy and without any springback.

A low ovality of the bend can be achieved with minimal reduction in wall thickness. 

Surface manipulation, improvement of the material characteristics

In addition the rolling process also allows a defined manipulation of the surface. In certain circumstances, even the material characteristics are improved. The tube forming machine from transfluid is equipped with a simple bending device. The shaped tube is then very simply bent with this, with very little force being required. The rotatory shaping brings the material to the plasticising zone. Thus tubes can be simultaneously bent with relatively tight radii without mandrels. Because the tube springback is only minimal due to the plasticised material, the bending angle achieved is almost identical to the selected angle of the bending machine.

With their new incremental tube forming technology, transfluid offers the option to process such custom manufactured tubes (tailored tubes) up to a diameter of 90 mm. The solution for tubes thus opens up new dimensions in tube processing whilst simultaneously driving the progress of product design further forwards. So, we can be excited about the future.
