A kind of straightening treatment method of plastic pipe

Abstract

The invention belongs to the technical field of plastic pipes, and in particular relates to a method for straightening plastic pipes, comprising the following steps: Step 1: cleaning the inner and outer walls of the plastic pipes. Step 2: Dip the sponge block into lubricating oil, then pass the sponge block through the plastic tube, and coat the inner wall of the plastic tube with lubricating oil. Step 3, using a plastic pipe straightening device to straighten the plastic pipe. Step 4: Clean the inner wall of the straightened plastic pipe to remove the residual lubricating oil. The invention adopts hot water to heat the plastic pipe to be straightened, which ensures that the plastic pipe is evenly heated and avoids cracking of the plastic pipe in the process of straightening the plastic pipe. The plastic pipe straightening device of the present invention is used to straighten the plastic pipes, which can ensure that the axes of the plastic pipes are on the same straight line, and has high straightening accuracy.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, and in particular relates to a method for straightening plastic pipes. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, plastic pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall, easy construction and maintenance, and long service life. Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. However, plastic pipes also have a low softening temperature and are easily deformed when heated. Especially the plastic pipes exposed outdoors will be bent and deformed after being exposed to the sun in summer, resulti...

Problems solved by technology

[0005] The invention provides a processing method for straightening plastic pipes, aiming to solve the following problems when using a hair dryer to straighten plastic pipes: (1) When heating with a hair dryer, it is necessary to move the hair dryer back and forth along the length direction of the plastic pipe , the operation is cumbersome and it is easy to cause uneven heating of the pipe. During the process of straightening the plastic pipe, the part of the plastic pipe that is less heated is prone to cracking; (2) Straightening the plastic pipe by hand cannot guarantee that the plastic pipe will return to its original shape. poor precision
