Description

Technical Field

[0001] The invention relates to the technical field of metal stamping, in particular to a stamping process die for automobile parts. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] Of the world's steel, 60-70% is in the form of plates, most of which are stamped into finished products, including automobile bodies, chassis, fuel tanks, radiators, boiler drums, container shells, and iron core silicon steel sheets for motors and electrical appliances.

[0004] The stamping process, stamping die and stamping material together constitute the three elements of stamping processing. Only when they are combined with each other can stamping parts be obtained. Among them, the stamping die is the mold used for stamping, referred to as the die. The die is a special tool for batch processing of materials (metal or non-metal) into the required stamping parts. The accuracy of the stamping die directly affects the quality of the stamped product.

[0005] There are many forms of stamping dies. According to the nature of the process, they can be divided into blanking dies, bending dies, drawing dies, forming dies and riveting dies. Different dies are suitable for different stamping processes.

[0006] With the improvement of sheet strength and the complexity of product structure, traditional stamping dies are gradually unable to be applied to the processing of high-precision and complex-shaped stamping parts due to their over-reliance on human factors and defects that are difficult to control. Specifically for the forming of automotive parts, when using traditional stamping dies for stamping of diversified parts, the following problems generally occur:

[0007] 1. The stamping form is single and cannot adapt to the diversified stamping processing of different automotive parts, which affects the stamping effect.

[0008] 2. The mold size is single and inconvenient to replace, and cannot be adapted to the stamping of automotive parts of different shapes.

[0009] 3. The matching accuracy between the stamping upper die and the stamping lower die is poor, which affects the quality of the stamping parts.

[0010] 4. During multiple stamping processes, it is inconvenient to transfer parts between different workstations, which reduces stamping efficiency.

[0011] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
