Processing characteristics of automotive stamping parts

Stamping parts used in the automotive industry are called automotive stamping parts, and automotive stamping parts are particularly important for the entire car. According to statistics, there are probably thousands of stamping parts in a car. The processing of automotive stamping parts is also a huge challenge for stamping factories, because of its high precision requirements and strict requirements for the entire production process, and it must pass the IATF16949 certification. Today, I will introduce the processing characteristics of automotive stamping parts. 1. The design of the stamping process depends on the accumulation of social experience and data information. Because there are many human factors and uncontrollable factors in the whole stamping process of automobile stamping parts, simply using sheet plastic deformation theory to innovate stamping design schemes cannot achieve the expected goal. The basic theory is applied with strict standards. Nowadays, the plastic deformation test analysis system only has the function of certified processing technology. The key to the stamping design of automobile stamping parts is to rely on long-term accumulated production and manufacturing social experience and accumulated data information. 2. The stamping process is more common in the composite process. Because the stamping parts are large in size and complicated in appearance, precise positioning is difficult and moving is troublesome. Therefore, stamping parts mostly use compound molds, and very rarely use progressive molds. For narrow and long parts, sometimes multi-process molds or collaborative installation are not used for stamping molds. 3. The basic technological process of cold-extrusion stamping parts is the forming process, the press-side punching machine process and the reverse side plastic and beauty process. The molding process is an important process. In order to obtain sufficient plastic deformation and transformability of the stamping parts, and to improve the stiffness of the stamping parts, the forming process generally uses the deep drawing process instead of the pressing process. 4. In the application work, the cabinet has a large countertop and a press with a small pound-level relativity. The press regulations for suppressing automotive stampings are generally larger cabinet countertops during work to incorporate relatively large structural specifications. Because the stamping parts are thinner using plates and the deformation force is small, the reasonable load capacity of the press does not need to be very large. The precision of the press is also thin due to the use of plates in the stamping parts, the mold gap is small, and the precision of the stamping parts themselves are also relatively high. Commonly seen closed test four-point mechanical press. [Recommended recommendation] Learn more: The advantages of electrolytic polishing of the motor housing.
