Advanced tube bending with a ‘round’ design
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.
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.
