Background technique

In recent years, with the popularity of family cars, the automobile manufacturing industry has developed rapidly. Due to the continuous improvement of people's aesthetic requirements, the upgrading of automobiles has accelerated, and the development, design and production cycle of stamping dies for automobile panels has also been shortened. In order to ensure quality and quantity, meet customer needs and save costs, the difficulty in the mold production process has been greatly increased, especially for molds used in large key covering parts such as automobile body side panels, the mold structure is extremely complex, and the upper mold The connection between the seat and the lower mold seat is unstable, and at the same time, the upper mold seat exerts pressure on the lower mold seat for a long time, which will cause the lower mold seat to separate or plastically deform, and shorten its life. It is difficult for the mold to meet the ideal requirements. The direct reason is that the dimensional accuracy of the stamping parts cannot reach the target value of the product, and the fitter needs to carry out repeated debugging and rectification of the mold, which makes the manufacturing cycle quite long and the product productivity is low. Moreover, the main impact on the stamping cost is The factors are material utilization rate and one-shot cost. The higher the material utilization rate, the lower the one-shot cost and the lower the cost. In the stamping process of a large automobile panel, the auto panel is easy to be offset during the stamping process, which will lead to low and inaccurate stamping precision. Therefore, a multi-functional automobile panel stamping die is urgently needed.
