Polyethylene pipe forming system and forming process

Abstract

The invention provides a polyethylene pipe forming system and a forming process. The polyethylene pipe forming system comprises a base, an execution unit, a fixing unit and a fixing cover. The polyethylene pipe forming system and the forming process solve the problems that in the existing process of polishing joints of polyethylene elbows, the polyethylene elbows are difficult to fix due to the fact that the polyethylene elbows have a certain radian, the processing effect of the polyethylene elbows are affected due to the fact that the polyethylene elbows easily shake in the fixing and polishing process, at present, the polyethylene elbows are mostly treated in the mode that joints of the polyethylene elbows are manually polished in a handheld mode, and the efficiency of polishing the inner walls and the outer walls of the joints of the polyethylene elbows by manually holding the polyethylene elbows is low.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a polyethylene pipe forming system and a forming process. Background technique [0002] Polyethylene pipe is a pipe made of polyethylene, which is a highly crystalline, non-polar thermoplastic resin. The appearance of the original polyethylene is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. The polyethylene elbow refers to the turning part of the plastic pipe; the function of the polyethylene elbow is mainly used to connect the straight pipes on both sides of the bend. In the production process, polyethylene elbows are mostly made of polyethylene straight pipes that are divided into a small section of straight pipes and bent by thermoplastic. [0003] After the segmented polyethylene straight pipe is thermoplastically bent into a polyethylene elbow, the polyethylene elbow in...

AI Technical Summary

Problems solved by technology

[0003] After the segmented polyethylene straight pipe is thermoplastically bent into a polyethylene elbow, the polyethylene elbow interface is rough and uneven during use, resulting in poor sealing performance after the polyethylene elbow is connected to the polyethylene straight pipe. The interface of the polyethylene elbow is polished. At present, the following problems mainly exist in the process of grinding the interface of the polyethylene elbow: the polyethylene elbow has a certain curvature; it is difficult to fix the polyethylene elbow, and the fixed During the grinding process, the polyethylene elbow is prone to shaking, which affects the processing effect of the polyethylene elbow, and at present, the processing of the polyethylene elbow is mostly manual and the interface of the polyethylene elbow is polished by hand; The polyethylene elbow is inefficient in grinding the inner and outer walls of the interface of the polyethylene elbow
