If you carefully observe the produced automobile stamping parts, you will find that there are concave convex on the product surface, which affects the quality of the whole workpiece. To improve this situation, we must first find the root of the problem before we can formulate relevant solutions. Stamping manufacturers have also realized the seriousness of this problem, so they have begun to improve.

For the concave convex of stamping gold surface, most of them are caused by impurities attached to raw materials or stamping dies; Or in the stamping process, the die is collided; The height of the raw material conveyor belt is not reasonably adjusted; Deformation of station tools, etc. These problems mentioned above may cause deformation and concave convex of stamping parts.

In addition to individual reasons, they will also deform the stamping parts. These concave convex stamping parts need to be treated differently and can not be applied to automobile parts. If possible, it should be repaired in time. If the deformation is serious, it can only be discarded.

Automotive stamping parts are widely used in industrial products, and in order to obtain ideal stamping products, both stamping processing methods and stamping equipment should adapt to their materials. Moreover, we know from the stamping parts manufacturers that the smooth forming of stamping parts and the forming quality are related to some properties.

In fact, the performance is mainly worth the forming limit, die sticking and shape freezing of stamping parts. The forming limit mainly refers to the large deformation degree of stamping raw materials in the forming process, and on the premise of ensuring no fracture. In many cases, we regard the forming limit as the fracture resistance of materials, that is, the better the fracture resistance of stamping materials, the higher the forming limit.

The mold adhesion and shape freezing, that is, the ability of the material to obtain the mold shape in the stamping process and obtain the shape in the mold, there are many related influencing factors, so we should pay attention to all aspects and try to avoid the impression of the material performance, so as to make the stamping parts produce large shape errors.
