TUBE BENDING Fast systematic tool change transfluid simplifies complex tube processing with an automatic tool change system

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.

The new pipe bending machine DB 40120-CNC-VE by transfluid changes tools automatically.

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.

The transfluid machine permits bending radii of 1 x D and more for tubes with diameters up to 127 mm while reducing wall thicknesses from 2 mm to 1.5 mm. 22 IMT March 2017

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.
