Focusing on the difficulties of wrinkling, twisting and springback for S-shape pickup longitudinal beam, preliminary part analysis was conducted, and combining with CAE simulation analysis of stamping, the problems were solved from six aspects, namely, material optimization, one-time forming of pressing and flanging, open design in pressing and flanging, over bending, using reasonable forming clearance between punch and die, and designing elastic sensing detection and float lifting. The results show that the one-time forming process of pressing and flanging effectively controls the material flow during the forming process, and the product does no longer wrinkles or twists. Simultaneously, over bending reduces the springback amount during the forming process. In terms of die design, open design in pressing avoids damaging the product, and designing a reasonable clearance between punch and die not only improves the service life of insert, but also further controls the springback of product. The practical results of this process are good and meet the expected requirements, which not only improves the product quality but also reduces the production costs.
