Machine for bending tubes, incorporating push mechanism - has hydraulic push mechanism carried on longitudinally mobile carriage operating in conjunction with bending wheel and rotating arm that clamps end of tube

摘要

The bending machine has an extended bed (1) with the bending tool (2) at one end. The bending tool has a wheel (3) and a bending arm (5) mounted in rotation about the axis of the wheel. The arm has a jaw (6) that is applied laterally against the tube to be bent. A carriage (10) moves longitudinally on the bed, and carries a rotating clamp (13) that grips the end of the tube. A bar (14) is applied laterally against the tube, and is driven in translation parallel to the axis of the tube. A pusher carriage (17) moving along the longitudinal axis of the bed carries a hydraulic actuator (23). The actuator can be fitted with different terminations to adapt to the tube being bent.
