Manufacturing method of integrally shaped pipe having connecting part

Abstract

The invention discloses a method for manufacturing an integrally formed pipe with a connecting part, which is characterized in that it comprises the following steps: preparing an elastic pipe according to the shape of the integrally formed pipe; setting the elastic pipe on a forming rod; assembling a mold to make the A cavity is formed between the inner surface of the mould, the elastic tube and the forming rod; thermoplastic resin is injected into the cavity for molding; the mold is demoulded, and the forming rod is taken out. The integrally formed pipe obtained by using the invention can replace the existing pipe joint connection mode, and because it is integrally formed, problems such as joint falling off will not occur, and the assembly workload during use is also reduced.

Description

technical field [0001] The invention relates to a method for manufacturing an integrally formed pipe, in particular to a method for manufacturing a pipe which can replace a pipe joint and integrally form a plurality of branched elastic pipes. Background technique [0002] In some machinery and equipment, especially in chemical equipment, various pipeline structures are involved. Among them, an elastic tube is often used to transport liquid or gas. When it is necessary to connect multiple elastic tubes (such as bifurcations), Or when it is necessary to connect two elastic tubes with different calibers, or even connect the elastic tube with a functional plastic device, the existing method is to use a pipe joint to sleeve the elastic tube on the pipe joint, because the elastic tube has a certain expansion ability , When the pressure inside the pipe is high, it is prone to leakage and even falls off from the pipe joint. In order to prevent the leakage o...

[0002] In some machinery and equipment, especially in chemical equipment, various pipeline structures are involved. Among them, an elastic tube is often used to transport liquid or gas. When it is necessary to connect multiple elastic tubes (such as bifurcations), Or when it is necessary to connect two elastic tubes with different calibers, or even connect the elastic tube with a functional plastic device, the existing method is to use a pipe joint to sleeve the elastic tube on the pipe joint, because the elastic tube has a certain expansion ability , when the pressure inside the pipe is high, it is easy to leak and even fall off from the pipe joint

In order to prevent the leakage of liquid or gas, the connection between the elastic pipe and the pipe joint is required to be reliable. In order to solve this problem, in the prior art, fastening chucks are often used to fix it, or adhesives are used to bond it, and heat-shrinkable tubes are also used to heat Shrinked and closed, however, leakage will still occur in this way, and at the same time, due to the need for fastening operations at each connection of the pipe joint, as the number of connected pipelines increases, the work intensity increases, which also leads to operating costs increase, and even the event that the operator missed the fastening operation
