In the automobile market, we will find that in addition to the relevant parts and components of the automobile, the automobile stamping products also exist. The difference is that they are the parts and components materials that need to be processed, welded, or completed by other processes. In particular, what impact do these stamping parts have on the automobile?

It is understood that how automobile stamping parts directly affect the effect of automobile parts. If they have problems, then, when the parts are manufactured successfully, there are certain problems with the parts. If this situation is used in the automobile, it will inevitably lead to the quality problems of the automobile, thus affecting the use of the automobile.

Therefore, when we select and purchase automotive stamping parts in the market, we must pay special attention to the reliability and safety of both functions and quality, which is the main condition to ensure the quality of the car, the sound operation of the car and the long-term use.

In the production process of automobile stamping parts, there will be such and such problems as abnormal traces, bright spots, bright traces, etc. will appear when the surface is polished by oilstone, scratches and bumps are generally caused by carelessness, and the turnover of parts will also occur easily, and the more turnover times, the more chance of bumps and scratches.

Methods to ensure the quality of automobile stamping parts:

1. When the automobile stamping parts are stretched, they will be compressed and deformed to produce wrinkle. In order to avoid this kind of phenomenon, we can increase the internal tensile stress to eliminate wrinkles, and also increase the tensile reinforcement and reduce the radius. If he deforms locally, our tensile force will be higher. If the deformation of the external material is too large, there will be cracks. If we want to avoid this problem, we need to cut first to ensure the quality of the blank

2. If the tensile deformation force of the locally deformed stamping part is higher than that of the side wall material, it will lead to bi-directional elongation deformation. If the external material can not supplement the internal part, it will be considered that the deformation is too large, resulting in fracture. To overcome this situation, blanking should be used first, which can ensure the quality of the blank edge section, so as to improve the blank edge state, and appropriate increase should be adopted Material size to effectively determine the size of the flanging blank.

3. There will be a lot of bright spots and bright marks on the surface polished by oil. If there are scratches or bumps, they are caused by our operator's carelessness. Of course, scratches are easy to appear when parts are turned. If there are more times of turning, there will be more chances of collision.
