Abstract: It focused on the analysis and control for the deformation after the large sheet metal parts forming. In view of the product structure characteristics, using the theoretical analysis and test, and combining with the actual production, the causes of deformation were analyzed, and a scientific and reasonable control method were put forward, and the forming process and forming structure were obtained. It reached the technical requirements of product flatness, and realized the high quality products, and gained valuable experience data.
