Abstract

The pipe bending machine belongs to the field of pipe bending by winding or rounding. The aim of the invention is to automate the unloading of bent pipes on a pipe bending machine. The pipe bending machine includes a bending mechanism with a template, in the guides of which is located a slide for longitudinal displacement of the pipe. What is new about the machine is that it is equipped with a rotating beam, assembled on the slide so that its axis of rotation is located parallel to the axis of longitudinal displacement and on the beam. An additional clamping mechanism is located in front of the clamping sleeve of the slide, while the bending mechanism is designed to be able to move in a horizontal plane perpendicular to the axis of longitudinal displacement.
