Pipe bending machine - feed mechanism with return rope attached to drum and press support controls bending together with pulling rope

摘要

The bender includes an induction heater, and after the placement of the pipe in the press support (2), the guide rollers (4) are moved apart to let through the blank towards the clamp at the end of the bending arm (7). The pressure is set according to the type of pipe with weight (G) on lever (17) while compensating roller (16) determines the limit of the torsion moment. The arms ratio is set by sector and pinion (18/19), and depression of the control button turns on drum (9) of the pull rope (12) with switching of the inductor ensuring the heating of the pipe.
