Abstract： This study focuses on a distinctive motor support product. Through detailed process analysis，the development shape and forming force were calculated. The setting of critical dimensions leads to fluctuations in the size chain， particularly affecting high-side-wall U-shaped bending parts which are prone to springback. By employing upsetting pressure correction and side-pressure roof structures，the impact of springback is effectively mitigated. The innovative introduction of a doublelayer concave die，combined with gradual deformation，appropriate die material selection，and TD treatment， transitions the bending gap from large to normal until the final upsetting pressure correction. This approach cleverly alleviates complex deformations caused by bending of the reinforcing bar at the bottom of the connected side wall，thereby further controlling springback. Mass production verification has confirmed that this mold efectively addresses production challenges and provides innovative solutions for similar products. Key words： processability analysis； upsetting correction; side pressure ceiling； double-layer die；slow deformation
