Abstract: The structural characteristics of the tail gate outer panel were introduced, and the collapse and springback defects of the upper spoiler of the stamping part were studied. The research direction was evaluated and analyzed by using the fishbone diagram, and the main influencing factors were determined. It put forward the solutions by checking the possible questions one by one, and analyzed the causes of the springback problems in detail. The rectification plan was verified by means of the AutoForm software. Compared with the results, an accurate rectification plan was finally put forward, and the correctness and effectiveness of the optimization plan was verified on site, which could provide referenced for similar problems of similar parts.
