摘要：
The unreasonable residual stress field in sheet part has an adverse effect on the dimensional accuracy and performance. A forming method combined stamping and forging was proposed to reduce the residual stress of the sheet part. The residual stress field in 2024 aluminum alloy V-shaped piece after bending and forging was analyzed by the finite element software Abaqus. The results showed that the stamping-forging forming process can significantly reduce the residual stress in round corner of V-shaped piece, and simultaneously decrease springback and improve the dimensional precision of sheet part.
