Transfluid Develops Efficient Tube Bending Process For Smallest Bending Radii

Schmallenberg, Deutschland (PressExposure) July 21, 2011 -- A small bending radius is easier to produce than a big one. A world turned upside down? The supplier of solutions transfluid exceeds the possibilities of conventional processes in the development of a new tube bending technology. Usually, bending radii can rarely be assembled smaller than 1 x D with higher tube diameters. transfluid has just designed an efficient process with a sophisticated bending radius of 0.8 x D for high-grade steel tubes. The transfluid Maschinenbau GmbH will be presenting more new, advanced solutions at the EMO Hannover 2011 from September 19 to 24.

Efficiency and at the same time high-quality results are factors in the tube processing sector that are crucial for success. Regarding this matter, the bending standard is far from it: For tube clamping in conventional single bend bending processes clamping lengths are required that have to be cut after bending. A transfluid customer was looking for a solution without cutting after bending with regard to this unnecessary loss of material. The challenge was the development of a tube bending machine for single high-grade steel bends with 70 x 2 mm. Furthermore, a center bending radius of 0.8 x D, the avoidance of a bend exit ovalization and a reduction of the wall thickness of less than 3 per cent had been desired.

"With conventional processes such requirements cannot be realized, especially with those high-grade steel tubes. Our solution is a procedure that does not point the bends after the rotary draw bending process but presses them", explains transfluid CEO Gerd Nöker the new development. With their pipe bending machine the german specialists guarantee a reduction of the wall thickness of 0 per cent. This at the same time offers the advantage of additional material saving. Also, an ovalization of the bend exit can be avoided with the transfluid pipe bending process. "A cutting of overlenght of the components can be completely avoided. They can be locked in further processes immediately after production. If required, the next steps for further tube processing can be assembled in the same machine", emphasizes Nöker the efficiency of the transfluid technology.

Tool-related bending angles between 10° and 180° are possible. If appropriate cutting lengths are locked in the process a cycle time of 3.5 seconds is possible even with tube sizes like in the example mentioned above.

"What we can do best is realizing an idea beyond standards. That is why we have made possible not only a solution with an impressive bending radius but also designed an extraordinarily efficient complete process. Considering the mere machine investment it is clearly below the investment for a CNC tube bending machine with multiple tooling that is usually deployed for such sophisticated tube processing", Gerd Nöker concludes. Visitors of the EMO Hannover can experience the solutions of the global player in hall 14, stand B 45. For various requirements transfluid will be presenting the solution for tubes.
