Intermediate frequency induction tube expander

Tube expanding machine is also known as hot expanding machine, as the name implies, that is the small diameter of the steel tube tube billet hot expanding for large diameter steel tube, the hydraulic tube expanding machine in the expansion of the pipe first of the steel tube end groove formation, and then put the steel tube in the corresponding diameter of the fixture hole.

Working process of medium frequency tube expanding machine: when the mold is opened, plastic parts under the action of shrinkage force to wrap the mold core, with the moving mold downward movement, the next line to a certain distance, fixed on the drawing plate on the template pull the plate, so that plastic parts from the core, to achieve automatic demoulding products.When the mold is closed, under the joint action of guide groove, guide block, guide sleeve and guide column, the mold is closed accurately and the wall thickness of the product is even, so that the product is qualified.Using medium frequency induction heating technology while increasing the difficulty of mold manufacturing and complexity, but under the condition of mass production, reduce the generation of waste, shorten the molding cycle, improve the quality of the pipes, at the same time reduce the hydraulic equipment interchanged frequent maintenance and repair, has the function of automatic constant temperature, prevent the too high temperature, wall of fracture or damage)
