| This paper aims to solve the bodyside forms springback, which affects the matching accuracy in the process of stamping forming. It also forms small local defects on the surface of the parts, which affects the product quality. In this paper, based on the numerical simulation technology, Autoform software is used to accurately simulate and predict the stamping springback of the bodyside surface. The numerical calculation results are combined with the actual production experience to compensate and control the geometric model of the bodyside. The final test results show that the qualified rate of rear side panel parts produced by the above method is more than 90%. Using numerical simulation to analyze the springback compensation of bodyside can reduce the defects in the forming process, improve the dimensional accuracy, and effectively solve the problem of large springback of bodyside. |
