Description

This machine is a mandrel bending machine that was designed exclusively for the production of pipe bends with pipes of 40 mm – 90 mm outer diameter with a maximum 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 length/usable length for mandrel bending: 3000 mm • Radius range max. 270 mm • Bending height 1050 mm • Electro-hydraulic drive • Clockwise bending direction • With hollow shaft to achieve small radii • Counter bearing rotates • Rotates 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 angle of rotation unit can move just behind the bending tool • With automatic sequence; one of the following functions can be activated via a key switch. • Function activation can be done either via foot switch or hand switch • At the manual operating level, all functions can be activated using a button in jog mode. • In semi-automatic operating mode, the pipe is clamped after the first trigger, bent after the second trigger, and then the machine returns to its starting position. • Manual tool retraction • Counter bearing moves hydraulically to the pipe • Automatic tool locking • Hydraulic pipe clamping forwards/backwards • Hydraulic components: Rexroth
