Problems solved by technology

In the cutting process of plastic hose, due to its own material factors, it is more difficult to make the quality of the end face after cutting better.
If the method of sawing is used, the end surface of plastic hoses such as PVC hoses is very rough after sawing. At the same time, due to the toughness and viscosity of the hose, the quality of the end surface is still not good after grinding; During the cutting process, the plastic hose is cut after being flattened, so the rounded end surface is uneven and irregular in shape, and cannot meet high quality requirements; Shrinkage deformation of cutting surface

Embodiment 1

[0027] This example is to cut a plastic hose made of soft polyvinyl chloride. It is required that the size be processed to Φ50*Φ60*Φ150, and the end surface roughness Ra25. At the same time, the batch is large, and the two ends are required to be perpendicular to the outer circular busbar, and the end surface should be cut Good flatness. After testing, the following processing methods can guarantee the quality requirements. Its processing method is as follows:

[0028] The first is the production of tooling.

[0029] Tooling 1 core rod: the length of the core rod is turned to 250mm. The diameter of the mandrel should be appropriately smaller than the inner diameter of the plastic hose. Here, the inner diameter of the plastic hose is Φ50, so the outer diameter of the mandrel is turned to Φ48. The material of the mandrel is a nylon rod, and the purpose is to prevent the knife from chipping because the mandrel is too hard when the mandrel is cut through the plastic hose.

Abstract

The invention relates to a cutting and processing method of a plastic flexible tube. The cutting and processing method of the plastic flexible tube of the invention is characterized in that the procedures comprise as follows: (1) a whole roll of plastic flexible tube is cut; (2) a core rod is inserted into the inside supporting circle of the plastic flexible tube cut in procedure (1); (3) the two end surfaces of the plastic flexible tube are cut; (4) the plastic flexible tube is taken down from the core rod. The plastic flexible tube processed by adopting the method of the invention has the advantages that the efficiency is high, and the rate of finished products is high; the length and the size are precise, the verticality between the end surfaces and the axial line is high, and the end surface is flat.

Description

technical field [0001] The invention relates to a method for cutting and processing plastic hoses. Background technique [0002] When cutting the hard tube, generally, methods such as sawing, grinding or turning can be used. In the cutting process of the plastic hose, due to its own material factors, it is more difficult to make the quality of the end face after cutting better. If the method of sawing is used, the end surface of plastic hoses such as PVC hoses is very rough after sawing. At the same time, due to the toughness and viscosity of the hose, the quality of the end surface is still not good after grinding; During the cutting process, the plastic hose is cut after being flattened, so the rounded end surface is uneven and irregular in shape, and cannot meet high quality requirements; The cut surface shrinks and deforms. Contents of the invention [0003] The object of the present invention is to propose a method for cutting and processing plastic hoses, so as to...
