The stainless steel pipe clamping and pressing type connector machining device comprises a rack, an inner mold assembly and an outer mold assembly, wherein the outer mold assembly is fixedly connected with the rack; the inner mold assembly is rotationally connected with the rack; the outer mold assembly comprises an outer barrel and a plurality of outer mold plates; the plurality of outer mold plates are arranged in the outer barrel and define a columnar structure, and the outer mold plates slide in the radial direction of the outer barrel; the inner mold assembly comprises an inner barrel and a plurality of innermold plates; the plurality of inner mold plates are arranged in a cavity of the inner barrel and define a columnar structure, and the inner mold plates are in sliding connection in the radial direction of the inner barrel; and the inner mold plates are sleeved with the outer mold plates. According to the stainless steel pipe clamping and pressing type connector machining device and the machining method, the machining efficiency is high, and safety is high.

Description

technical field [0001] The invention relates to processing equipment and a processing method for forming a nozzle, in particular to a stainless steel pipe clamping type interface processing equipment and processing method, belonging to the field of pipe fitting processing. Background technique [0002] The stainless steel pipe compression joint is a socket pipe fitting with a special sealing ring to connect the joint, which is often used in various fluid conveying pipelines. It has the characteristics of anti-drawing, anti-rotation, simple and convenient installation. Compression joints are usually formed by a water expansion machine or a rubber expansion machine. The manufacturing process steps are: (1) Put the pipe into the mold cavity, close the mold, and seal the end of the pipe with a punch; (2) Put water or The polyurethane glue is punched into the inside of the pipe by the sealing punch to stamp the inside of the pipe; (3) Keep the pressure until the pipe is formed. ...

AI Technical Summary

Problems solved by technology

However, the existence of high-pressure water makes the operation of the expansion machine dangerous and uncontrollable. The polyurethane glue used in the expansion machine has a large loss and high cost. The processing of the above two types of equipment is unstable and has a certain reject rate. , and it is more complicated to change the mold when processing different pipe diameters
