摘　　要：分析了管接头的缩口—轴压—胀形复合成形过程中弯曲现象产生的原因，运用刚塑性有限元法分析了模具圆角半径和摩擦因子对该现象的影响，最后给出了减小弯曲现象的措施。Abstract In this paper, the reasons of a bending defect generated in a nosing-axial pressing-building compound forming process are analysed. The influences of die corner radius and friction factors are analysed by using the rigid-plastic finite element method. At last, the measures for reducing the bending defect are given.
