The stamping part is a forming method of applying a force to a plate, a strip, a pipe, a profile, and the like by a press and a mold to cause plastic deformation or separation to obtain a workpiece of a desired shape and size. Stamping and forging are the same plastic processing, collectively called forging. The stamping parts are mainly hot rolled and cold rolled steel sheets and strips.

Introduction of stamping parts

 

Cold stampings are generally no longer machined or require only a small amount of machining. The accuracy and surface condition of hot stampings are lower than that of cold stampings, but they are still superior to castings and forgings, and the amount of cutting is small.

 

Stamping is an efficient production method. It adopts composite molds, especially multi-station progressive molds. It can complete multiple stamping processes on one press to realize the whole process of unwinding, leveling and punching to forming and finishing automatic production. High production efficiency, good working conditions, low production costs, and generally can produce hundreds of pieces per minute.

 

Stamping is mainly classified according to the process, and can be divided into two major categories: separation process and forming process. The separation process is also referred to as blanking, and its purpose is to separate the stamped parts from the sheet along a certain contour line while ensuring the quality requirements of the separated sections. The surface and intrinsic properties of stamping sheets have a great influence on the quality of stamped products. The thickness of stamping materials is required to be precise and uniform. The surface is smooth, no spots, no flaws, no scratches, no surface cracks, etc.; yield strength is uniform, no obvious Directionality; high uniform elongation; low yield ratio; low work hardenability.

 

Main feature

 

The stamping parts are mainly formed by stamping and stamping metal or non-metal sheets by means of the pressure of the press. The main features are as follows:

 

(1) Stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity, and after the sheet material is plastically deformed, the internal structure of the metal is improved, and the strength of the stamping parts is improved. .

 

(2) The stamping parts have high dimensional accuracy, uniform size with the same module, and good interchangeability. General assembly and use requirements are met without further machining.

 

(3) In the stamping process, since the surface of the material is not damaged, it has a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatment.

 

Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to increase their rigidity. Thanks to the use of precision molds, the precision of the workpiece can reach micron level, and the repeatability is high and the specifications are the same. It is possible to punch out the holes and the bosses.

 

Conclusion

 

Of the world's steel, 60 to 70% are sheets, most of which are stamped into finished products. The body, chassis, fuel tank, radiator piece of the automobile, steam drum of the boiler, the casing of the container, the iron core silicon steel piece of the electric motor and the electric appliance are all stamped and processed. There are also a large number of stamping parts in instruments, household appliances, bicycles, office machinery, living utensils and other products. Therefore, stampings are ubiquitous in our lives.
