Novel ultrahigh molecular weight polyethylene pipe flanging machine

Abstract

The invention discloses a novel ultrahigh molecular weight polyethylene pipe flanging machine which comprises a working table, a baffle and a fixed frame. The baffle and the fixed frame are fixed to the upper end of the working table. A pipe is arranged between the baffle and the fixed frame. One end of an air cylinder is connected with a support through a piston rod. One side of the outer wall ofthe support is fixedly connected with a flanging mold. The outer wall of the flanging mold is connected with a flanging convex block in a sleeved manner. An inner cavity is formed in the position, located on the inner wall of the flanging mold, of one side of the flanging convex block. One side of the inner wall of the inner cavity is fixedly connected with a fixed rod. Multiple liner blocks areevenly arranged on the outer wall of the fixed rod through second springs in a surrounding manner, a heat conduction piece is arranged at the outward extending end of each liner block, and an electricheating block is arranged at the position, located in the corresponding liner block, of one side of each heat conduction piece. The novel ultrahigh molecular weight polyethylene pipe flanging machineis simple in structure and easy to operate; automatic flanging of ultrahigh molecular weight polyethylene pipes can be achieved; and meanwhile, operation is stable, work efficiency is high, and laborforce is reduced.

Description

technical field [0001] The invention relates to the technical field of composite pipe processing, in particular to a novel ultra-high molecular weight polyethylene pipe flanging machine. Background technique [0002] Ultra-high molecular weight polyethylene is a linear polyethylene with an average molecular weight greater than 1.5 million. It has excellent comprehensive performance such as wear resistance, impact resistance, self-lubrication, and corrosion resistance. Ultra-high molecular weight polyethylene pipes are widely used in solid powder, solid-liquid For the material transportation of the mixture, one of the pipe connection methods in construction is to use flanging flange connection, that is, to put a standard metal flange on the end of the ultra-high molecular weight polyethylene pipe, and then flanging the end of the pipe , so as to realize the flange butt joint of the pipe. Since the ultra-high molecular weight polyethylene is in a high viscoelastic state when i...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that there are many processes, the heating and flanging process are separated, the work efficiency is low, the operation is troublesome, and the pipe flanging is prone to cracking during flanging, and the flanging quality cannot be guaranteed.
