How to process PPR pipe

Time: 2018-08-30 12:11 Author: admin Hits: Times
PPR pipe cutting is the basic process for producing pipe fittings, including pipe fitting cutting, port shape punching, punching and cutting. Pipe cutting is a process of stamping and separating. Compared with steel plate shearing, due to its own shape (hollow section), preventing the tube wall from being crushed during shearing is more complicated. At the same time, the design and manufacture of the mold is also high.

Compared with mechanical cutting, the pipe cutting speed is faster and the production efficiency is higher, which is suitable for mass production. Therefore, it has broad application prospects. However, due to the complexity of the pipe cutting process, the technology is not mature enough. Therefore, it is not widely used in production. This chapter mainly introduces various technologies and application scope of pipe shearing.
In the manufacture of pipe parts, the pipe must first be cut to obtain the length of the pipe. Pipe cutting mainly adopts two methods of machining and stamping. Mechanical processing includes saw cutting, lathe cutting, grinding wheel cutting, etc. Its advantage is that the quality of the cutting section is stable, but it is difficult to meet the requirements of mass production due to the low productivity.
The stamping process has high production efficiency, but the pipe wall is easily broken during cutting, resulting in section deformation and tilt. If a shear bar is used to cut common materials, the pipe must be squeezed and cannot be used. Therefore, it is very important to take special technological measures to prevent the pipe from being crushed during shearing to ensure the quality of the cutting section and meet the requirements of the pipe fittings. Here are some special PPR pipe cutting methods already used in production.
