TRANSFLUID DB4090 S

The present machine is a mandrel bending machine designed exclusively for the production of pipe bends with pipes of 40 mm – 90 mm outer diameter with a max. wall thickness of 20 mm or for processing solid materials up to 70 mm outer diameter (max. section modulus 64.7 cm³) and is therefore intended only for this purpose. Scope of delivery, machine equipment, basic equipment • Pipe feed length/usable length during mandrel bending 3000 mm • Maximum radius range 270 mm • Bending height 1050 mm • Electro-hydraulic drive • Clockwise bending direction • With hollow shaft for achieving small radii • Rotating counter bearing • Rotating up to 180 degrees with a maximum tool radius of 270 mm • Forward movement controlled via hydraulic cylinder with pressure valve • Retraction via hydraulic cylinder • Counter bearing opens wide so that the twist angle unit can move to just behind the bending tool • With automatic sequence, one of the following functions can be activated via key switch. • Function activation optionally via foot or hand switch • In hand operation mode, all functions can be operated via pushbuttons in jog mode. • In semi-automatic operation, the pipe is clamped after the first trigger, bent after the second trigger, and then the machine returns to its starting position. • Manual tool reset. • Hydraulic counter bearing moves to the pipe. • Self-locking tools. • Hydraulically clamped pipe forward/backward. • Hydraulic components: Rexroth
