Machining and forming method of compression-resisting leakproof shedding preventing pipeline joint

Abstract

The invention relates to a pipeline fitting, in particular to a machining and forming method of a compression-resisting leakproof shedding preventing pipeline joint. When the pipeline joint embedded with a metal pipeline connecting piece is machined, firstly, the metal pipeline connecting piece is machined; secondly, injection molding is carried out, when the metal pipeline connecting piece is machined, the side wall of the annular clamping groove on the outer wall of the metal pipeline connecting piece is machined into a semicircular concave shape so as to improve the joint connection degreeof the metal pipeline connecting piece and an injection material; and thirdly, the metal pipeline connecting piece is used as a mould core for injection molding. When in machining, two fan-shaped clamping grooves are symmetrically arranged on the end face of the top end of the metal pipeline connecting piece, and before injection molding, an annular lug boss is additionally arranged on the outer edge of the bottom end of the metal pipeline connecting piece. The processing and forming method improves the production efficiency of products, the joint connection degree and the firm degree of the formed pipeline connecting piece and the injection material and the quality of the pipeline joint, is insusceptible to breakage, is easier to be compression-resisting, leakproof, shedding preventing and the like.

Description

technical field [0001] The invention relates to a pipe fitting, in particular to a method for processing and forming a pressure-resistant, leak-proof and fall-off pipe joint. Background technique [0002] Various pipe joints are commonly used in pipe connection, especially the internal threaded elbow, internal thread straight head, etc., which are embedded with metal pipe connectors, and the outside of the metal pipe connectors is combined with the elbow by injection molding to form an integrated structure. The pipe connector is internally threaded for direct connection to pipe. The advantages of embedded metal pipe connectors are that the metal parts are pressure-resistant, leak-proof, and detachment-proof, etc., as attached figure 1 As shown, it is a schematic diagram of the shape of the internal threaded elbow with embedded pipe connectors. [0003] Due to the requirements of anti-pressure, anti-leakage and anti-off, in the processing and molding of similar anti-pressur...

Problems solved by technology

In addition, when the water pressure may be high, due to structural reasons, the pipes or pipe connectors are prone to cracking under the pressure of the water flow, causing water leakage, etc., which are common problems in various pipe joints.
