摘　　要：分析了传统的弯曲成形工艺,成形制件与模具零件接触的表面会形成压痕或拉伤,对于距离弯曲线较近的孔在弯曲过程中会发生变形,通过分析板料成形特点及弯曲成形原理,设计翻转弯曲模以消除压痕,提高制件成形质量。The traditional bending forming process was analyzed,the surface of the forming part in contact with the die would form indentation or strain.During the bending process,the hole closer to the bending line would deform.In order to eliminate the indentation and improve the forming quality of parts,the overturned bending die was designed by analyzing the forming characteristics and the forming principle of sheet metal.
