Methods to ensure the quality of automobile stamping parts

The general requirements for automotive stamping parts are very high, and the industry determines the degree of precision required. How can stamping parts processing plants ensure the quality of stamping parts when processing automotive stamping parts? Precision-More than 10 years of committed to the customized processing of automotive stamping parts, to provide customers in the automotive industry with customized and complete solutions. Next, we will introduce how the stamping factory can ensure the quality of automotive stamping parts. 1. When the automobile stamping parts are stretched, they will suffer from shrinkage deformation and produce wrinkles. In order to better prevent the occurrence of such conditions, we can increase the internal tensile stress to remove the wrinkles. Lifting the stretch ribs and the reduction of the half warp. If he deforms partly, then everyone's stretching force needs to be higher. If the external raw material deforms greatly, then cracks will appear. If you want to prevent such problems, you need to open the material first to ensure the quality of the blank. 2. If the tensile deformation force of the partially deformed stamping part is higher than that of the outer wall raw material, it will cause double stretching deformation. If the external raw material cannot fill the interior, it is considered to be too deformed and cause cracking. To get rid of this kind of situation, The cold stamping method should be used to open the material first to ensure the quality of the cross section of the edge of the blank, and then improve the edge of the raw material, and choose to increase the raw material specifications to reasonably clarify the specifications of the concave opposite edge blank. 3. The surface layer polished by crude oil will show many shining points and bright marks. If there are scratches or bumps, it is caused by the carelessness of everyone's actual operation staff. Naturally, the funds will be invested in the parts. In the case of turnover, it is also very prone to scratches. If the frequency of capital turnover increases, there will be more opportunities for impact.
