What is stamping metal parts?

Stamping part is a kind of forming processing method that applies external force to plate, strip, pipe and profile by press and die to produce plastic deformation or separation, so as to obtain the workpiece (stamping part) with the required shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The stamping blank is mainly hot-rolled and cold-rolled steel plate and strip.

What is stamping metal parts?

Stamping is a kind of forming and processing method that relies on press and die to exert external force on plate, strip, pipe and profile to produce plastic deformation or separation, so as to obtain the workpiece (Stamping) with the required shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The stamping blank is mainly hot-rolled and cold-rolled steel plate and strip. Stamping is an efficient production method. The use of compound die, especially multi-position progressive die, can complete multiple stamping processes on one press. The application technology of engineering geological exploration realizes the automatic production from strip uncoiling, leveling, blanking to forming and finishing. It has high production efficiency, good working conditions and low production cost. Generally, it can produce hundreds of pieces per minute.

Stamping is mainly classified according to process, which can be divided into separation process and forming process. A separation process is also called blanking. High-speed Copper drawing machine uses a full set of polycrystalline die. Its purpose is to separate the stamping parts from the sheet metal along a certain contour line and ensure the quality requirements of the separation section. The purpose of forming process is to make the sheet metal plastic deformation without breaking, In practical production, many processes are often applied to a workpiece. Blanking, bending, shearing, deep drawing, bulging, spinning and straightening are the main stamping processes.

Through the punch and die on the plate, strip, pipe and profile and other external force, make it produce plastic deformation or separation, so as to obtain the desired shape and size of the workpiece forming processing method, the workpiece is the stamping part.

What are the advantages of stampling process？

The production efficiency of the stamping process is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because stamping depends on the stamping die and stamping equipment to complete the processing. The stroke times of ordinary press can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute, and each stamping stroke can get a stamping part. When stamping, because the die ensures the size and shape accuracy of stamping parts, and generally does not damage the surface quality of stamping parts. Stamping can process parts with a large size range and complex shape, such as stopwatch of clock and watch, automobile longitudinal beam, panel and so on. With the cold deformation hardening effect of material during stamping, the stamping strength and stiffness are higher. Generally, stamping does not produce chips and chips, consumes fewer materials, and does not need other heating equipment, so it is a kind of material-saving and energy-saving processing method, and the cost of stamping parts is lower.

Due to the advantages of stamping, stamping is widely used in various fields of the national economy. According to statistics, 80% of bicycles, sewing machines and watches are stamping parts; 90% of TV sets, tape recorders and cameras are stamping parts; There are also food metal cans, steel precision boilers, enamel bowls and stainless steel tableware, all of which are stamping products using molds; Even the computer hardware can not be lack of stamping parts.
