With the continuous progress of industrial technology, pipe fitting stamping method, as an important metal processing technology, has been widely used in aerospace, automobile, motorcycle, machinery, chemical industry and other industrial sectors. In this paper, we will introduce the specific application of industrial pipe fitting stamping method and its advantages in detail.

I. Overview of the pipe fitting stamping method
Pipe fittings stamping method refers to the processing of pipe through stamping equipment to change its shape, size and performance, so as to meet the specific engineering needs of a processing technology. This technology belongs to the category of pipe deep processing technology, which has the advantages of high production efficiency, high material utilization rate, high product precision, etc. In the pipe fittings processing, common stamping methods include cutting, profiling, bending, roll forming and so on.

Second, the specific application of pipe fittings stamping method
1. Pipe cutting
Pipe cutting is one of the basic processes in pipe fittings stamping. According to production requirements, pipe cutting can be divided into mechanical cutting and stamping shear two methods. Mechanical cutting quality is stable, but low productivity; and stamping shear method can significantly improve productivity, and to ensure the quality of the cut section. Stamping shear according to the presence or absence of mandrel support can be divided into core cutting and coreless cutting. No core cut off because of its adaptability, more widely used.

2. Pipe notching
Pipe notching is a common process in pipe processing, widely used in motorcycles, bicycles, furniture and other industries in the processing of pipe fittings. The profiling process is mainly divided into two types: vertical profiling and diagonal profiling. In vertical profiling, the quality of profiling is improved by adjusting the geometric parameters of the convex mold or by pre-slotting and then punching the profiles. In the case of oblique profiling, it is necessary to adjust the position of the billet in the upper and lower clamping dies to ensure that the convex mold enters from the port to avoid the collapse of the top of the pipe.

3. Tube bending
Tube bending is another important part of tube processing. Pressure is exerted on the pipe by stamping equipment to produce plastic deformation, thus bending it into a shape with a certain curvature and angle. Bending process is widely used in automotive, motorcycle and other industries in the processing of pipe fittings, can significantly improve the structural strength of the product and aesthetics.

4. Pipe punching
Pipe punching is a key technology in pipe processing. The traditional pipe punching method using drilling, milling and other methods, although the quality is stable, but low production efficiency, difficult to meet the needs of mass production. With the development of stamping technology, pipe punching is gradually adopted stamping method, not only improve the production efficiency, but also simplify the mold structure, reduce production costs. Pipe punching can be divided into concave die punching and non-concave die punching according to the characteristics of its mold structure, of which non-concave die punching is more widely used.
