| Abstract: | In order to improve the springback of U-shaped aluminum alloy shell in the forming process and adjust the sidewall bending fillet, the reverse drawing was used to balance the internal stress to control the springback according to the structural features of the part. By adopting the technology of side extrusion and reasonably designed of die structure, the parts with good forming quality could meet the production requirements. It provided reference for forming the similar parts. |
