摘要：

针对锥筒形件剪切-拉深复合旋压时可旋性表征困难的问题，提出采用可旋性表征曲线对其进行表征。基于Abaqus软件建立了镍基高温合金锥筒形件全流程复合旋压成形有限元模型，分析了不同半锥角锥筒形件的破裂及起皱情况，进而获得其极限拉深系数；在此基础上，构建了锥筒形件剪切-拉深复合旋压成形的可旋性表征曲线，获得了锥筒形件复合旋压成形时的安全区以及破裂起皱区，并通过复合旋压工艺试验验证了有限元模型的可靠性。结果表明：采用剪切旋压时的半锥角为横坐标、拉深旋压时的极限旋压系数为纵坐标所构建的可旋性表征曲线，可实现对锥筒形件剪切-拉深复合旋压成形可旋性的有效表征。

Focusing the difficulty in characterization of spinnability for conical cylindrical part during shear-deep drawing composite spinning, the characterization curve of spinnability was proposed to characterize the spinnability. Based on software Abaqus, the finite element model of Ni-based superalloy conical cylindrical part in the whole composite spinning process was established, and the fracture and wrinkling of conical cylindrical part with different half cone angles were analyzed to obtain the limit deep drawing coefficient. Furthermore, on this basis, the spinnability characterization curve of conical cylindrical part in shear-deep drawing composite spinning was constructed, the safety zone and the fracture and wrinkle zone during the composite spinning process were obtained, and the reliability of the finite element model was verified by the composite spinning test. The results show that taking the half cone angle during the shear spinning as abscissa and the limit spinning coefficient of deep drawing and spinning as ordinate, the spinnability characterization curve is constructed to realize the effective characterization of spinnability in shear-deep drawing composite spinning for conical cylindrical part.
