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.
