摘　　要：介绍了离合器星轮精冲挤压成形原理,零件成形过程中工件产生纯剪切变形与挤压变形,以获得形状与尺寸精度较高的零件。设计了双面齿形压边圈与组合凹模的精冲挤压模,提高了模具强度。The free blanking and extrusion forming principle of clutch planetary gear was analyzed. In the forming process, shear deformation and compression deformation were occurred that high precision parts were obtained. A free blanking and extrusion die with double tooth blank holder and combined die was designed.
