PPR water pipe bending machining process

Abstract

The invention relates to a PPR water pipe bending machining process. A workbench, a clamping device, a bending device and a supporting device are included. The clamping device is mounted on the left side of the upper end of the workbench, the bending device is arranged on the right face of the clamping device, and the supporting device is arranged on the outer side of the clamping device and the bending device. According to the PPR water pipe bending machining process, the problems that during manual bending, firstly, a PPR water pipe is heated, then the PPR water pipe is bent, as the strengthof bending the PPR water pipe is hardly controlled manually, the bending angle of the PPR water pipe is disqualified, when existing PPR water pipe bending machining equipment carries out bending, firstly, the PPR water pipe is clamped and fixed, then the PPR water pipe is heated and then bent, as the interior of the PPR water pipe is not supported and fixed, the PPR water pipe is excessively bentor torn when bent, bending of the PPR water pipe is disqualified, and therefore the bending efficiency of the PPR water pipe is reduced can be solved.

Description

technical field [0001] The invention relates to the technical field of pipe production, in particular to a PPR water pipe bending process. Background technique [0002] PPR is a random copolymerized polypropylene synthesized by (PP and PE) gas phase method. Its structure is characterized by the random linking of PE molecules in PP molecules. With its excellent performance and wide application fields, it has been widely used in plastic pipes. It occupies a place in the market and is a recognized green product. PPR has the characteristics of high temperature resistance, good pressure resistance, small conveying resistance, long service life, health, health and environmental protection. During the use of PPR water pipes, it is usually necessary to bend the PPR water pipes before using them. [0003] The existing PPR water pipe bending processing equipment often has the following problems when bending PPR water pipes: [0004] (1) When bending the PPR water pipe manually, the ...

AI Technical Summary

Problems solved by technology

[0004] (1) When bending the PPR water pipe manually, the PPR water pipe is usually manually heated to soften it, and then the PPR water pipe is manually bent. When the PPR water pipe is bent, it is difficult to control the bending of the PPR water pipe manually. Therefore, the bending angle of the PPR water pipe is unqualified, thereby reducing the bending efficiency of the PPR water pipe;

[0005] (2) When the existing PPR water pipe bending processing equipment bends the PPR water pipe, it usually clamps and fixes the PPR water pipe first, and then heats and bends the clamped and fixed PPR water pipe. During the bending process of the equipment, the inside of the PPR water pipe is not supported and fixed, resulting in excessive bending or tearing of the PPR water pipe during bending, which makes the bending of the PPR water pipe unqualified, thereby reducing the bending efficiency of the PPR water pipe
