Embodiment Construction

[0031] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0032] The pipe joints seen on the market generally include pipes and pipe connectors, and the two are connected to form a connected state.

[0033] Such as figure 1 and 2 As shown in the figure, a processing method of a pipe fitting includes a processing method of a pipe material and a processing method of a pipe connector.

[0034] The processing method of described pipe comprises the following steps:

[0035] A1. Material selection: use stainless steel tube blanks with an iron content between 68-72% as raw materials;

[0036] A2. Positioning and fixing: Put one end of the pipe into the shrinking mold, and position and fix the pipe so that the shrinking die is coaxial with the pipe;

[0037] A3. Mold closing: Use an ...

Abstract

The invention provides a processing method of a pipe connecting part and belongs to the technical field of machining. With the adoption of the processing method, the problems of the need of cutting and the like when the pipe connecting part is processed in the prior art are solved. The processing method comprises a processing method of a pipe material and a processing method of the pipe connecting part. The processing method of the pipe material comprises the following steps: (A1) selecting materials; (A2) positioning and fixing; (A3) closing a mold; (A4) opening the mold; and (A5) processing threads on the end opening of the pipe material. The processing method of the pipe connecting part comprises the following steps: (B1) selecting materials; (B2) positioning and fixing; (B3) closing a mold; (B4) opening the mold; and (B5) expanding a left flange; (B6) expanding a right flange; (B7) grinding a conical surface; (B8) processing threads at one end of the pipe connecting part; and (B9) processing threads at the other end of the pipe connecting part. The processing method provided by the invention has the advantages that cutting is not needed when the pipe connecting part is produced and processed, so that the material can be saved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a processing method of a pipe joint. Background technique [0002] With the improvement of people's material living standards, pipes have been widely used in various fields, but the length of pipes is generally relatively long, which is not conducive to production, transportation and installation. Therefore, in the production process of pipes, it is usually necessary to cut off the pipes The pipes are cut into sections to facilitate transportation and installation, but after the pipes are cut off, the original sealing performance of the pipes will be lost, which requires the use of pipe connectors to splice the pipes together. [0003] In the prior art, pipe joints are usually processed by extruders. After searching, for example, Chinese patent literature discloses a production method of copper threaded pipe joints [Patent No.: ZL 02111631.8; Authorized Announcement N...
