How the medium-frequency pipe bending machine works

How the medium-frequency pipe bending machine works:
Push system of large radius of bend (2.5 D above) method is: with the diameter of the pipe using round of tightening steel pipe after induction coil of heating, with the rotation of the rocker arm, bend with the diameter of the pipe, without mandrel and core head, hole enlargement.
The method to make a small radius elbow (below 3D) is as follows: the pipe with a small diameter is expanded into a large diameter elbow through the heating of the medium frequency induction coil through the core rod and the ox horn core.
