What are the principles and properties of precision metal auto stamping parts?

There are many types of automotive stamping parts, and the more technical drawing parts are one of them; why the drawing parts are more difficult, depending on the product characteristics, the design is also difficult, and the mold test after the design is successful is also difficult. ; Usually, an experienced designer is required to design a mold with a reasonable structure, and an experienced mold worker is required to complete the mold test! When it comes to stamping parts, people only know one, but do not know the other; they only know the high requirements of precision metal stamping parts, but do not understand its stamping principle and nature. Today, Xiaobian will popularize the knowledge points for you.

The stamping principle of precision metal stamping parts is usually divided into two categories:

Separation principle: Under the action of the external force of the press, the stress of the deformed part exceeds the strength limit of the material, and the plate is broken and formed;

Principle of plastic deformation: Under the action of external force, the stress of the deformed part exceeds the yield limit of the material, but when the strength limit is not reached, only plastic deformation occurs, thereby obtaining a certain shape and size.

Five variants of the stamping process of precision metal stamping parts:

Three-dimensional pressing: redistribute the volume and transfer the material to a certain extent to change the shape, height and thickness of the blank;

Bending: Turn the flat material into a curved piece, with curling and twisting, etc.;

Calendering: stamping the blank into a hollow part of the desired size and shape, or making progressive changes in size;

Forming: Parts are locally deformed into the required size through a mold. This process is usually: forming, shaping, rolling, etc.;

Blanking: To separate a part of the material of the part, such processes are usually: blanking, punching, trimming, etc.
