Description

The present invention relates to a device for bending pipes, with the implementation of a pivot arm carrying ribs that serve to bend the male pipe around a fixed roller, and aims to pull the roller surrounding the pipe into the space between the rollers. For this purpose, the lever and the movable plate of the proposed fitting are provided with curvilinear slits in which / slides the axis of the withdrawn roller.

In FIG. 1 shows a view of the proposed adaptation at the top; FIG. its side view and FIG. 3 view of the cramp guide tube failing.

In the curved slot 2 of the non-sliding plate 3 (Fig. 1 and 2), the axis of the roller 5 slides, which is placed in the lever 1, mounted

on the common axis from the rollers 8 (Fig. 1) and the bearing roller 9. When laying the pipe 6, it is passed through the guide bracket 7 (Fig. 2 and 3), and the roller 5 is retracted into the slot 4 of the lever 1, after which the roller 5 is put in its original position and turned, the volume of the lever 1 tube 6 is curved around the roller 8 (Fig. 1).

The subject of the patent.

A device for pipe bending using a pivot arm carrying rollers covering the pipe and bending it around a fixed horn, characterized by using roller shaft b 1 of curvilinear cuts in lever 1 and fixed plate 3, in order to remove roller 5 when the aid is intended to bend the tube between the rollers,
