In order to put cold forging of spiral bevel gear into practice
a method dividing the material flow in the big end of dentiform cavity is put forward. And rigid-plastic finite element method is used to analyze the cold forging of spiral bevel gear.Comparing with the traditional cold closed-die forging process
this process based on divided flow method not only can ensure good filling of the forging tooth
but also greatly reduce the forming load.The qualified gear part needs only a small amount of grinding on the back cone.
