Embodiment Construction

[0021] Now in conjunction with accompanying drawing, the present invention will be further described.

[0022] The pipe joint forming process is applicable to the expandable and deformable pipe body 1. Taking the manufacture of a pipe joint with flanges at both ends as an example, the forming process is described as follows.

[0023] Such as figure 1 As mentioned above, first select the pipe body 1 that can be stamped and deformed, and a layer of jacket 2 that can also be stamped and deformed is respectively socketed at both ends of the pipe body, and the jacket is selected from a protective sleeve or a sheath with other characteristics. Step one, such as figure 2 As shown, the inner wall with the jacket at both ends of the pipe body is stamped radially to form a raised expansion area 101; step 2, as image 3 As shown, the raised expansion area is rolled and compacted along the axial direction of the pipe body to form a raised pipe joint 3, which is polygonal or ring-shaped...

Abstract

The invention relates to a pipe joint part molding process. The pipe joint part molding process is characterized by including the following steps: (1) the inner wall of a pipe body swells in the radial direction to form a protruding swelling area; (2) rolling compression on the protruding swelling area is carried out in the axial direction of the pipe body so as to form a protruding pipe joint portion, and a pipe joint part with the protruding pipe joint portion is manufactured and completed. Through the molding process, the pipe joint part with the integrated protruding pipe joint portion can be manufactured, integral molding is achieved, the process is relatively simple, the process steps like welding are omitted, time and labor are saved, and the molding efficiency is improved; in addition, the structure is free of welding lines, the sealing performance is good, the strength is high, and the application scope is wide.

Description

technical field [0001] The invention relates to the field of pipe joint forming and corresponding equipment, and relates to a pipe joint forming process. Background technique [0002] Pipe joints are parts used to connect pipes. Traditional pipe joints and pipes are usually connected by welding or welding flanges. Although the connection can be realized, the connection is inconvenient, time-consuming and laborious, and welding Sealing problems are prone to occur, and a large amount of heat generated during welding can easily change the shape of the welded part and concentrate thermal stress, affecting the mechanical properties and strength of the product. Although the existing pipe body has a flanging design, the flanging design is mainly used to limit the position of the pipe fittings such as flanges socketed on the pipe fittings, and the flange sealing end is formed by welding with the flange end. In this structure, once the flange is assembled, it cannot be easily disass...
