Abstract：
|
|
The diameters of the electromotor shaft shoulder can be changed in a small range.There are small fillet transitions between the shoulders.The open-die cold extrusion technology was used instead of traditional cutting method to manufacture the electromotor shaft shoulder,which was highly efficient and material saving.Two methods(one-step and two-step approaches)were analyzed.Based on the results of the simulation and experiment,one-step open-die cold extrusion process for motor shaft would be implemented successfully only in a small deformation degree(ε<3%),while satisfied corner could not be attained.The forming feasibility of two-step approach was verified.
