In this paper different cold forging processes of spiral bevel gear are studied based on the patent analysis. First of all, various design concepts are analyzed and classified according to the type of raw material and the motion of die during the forming process. Then, focused on the bulk billet, the parameters such as the mode of die motion, the size and shape of initial billet, the speed of punch and the coefficient of friction are selected to study their effects on the cold forging process. Finally, following the Taguchi method, numerical simulations are carried out to find out the suitable combination of process parameters. Material flow, stress and strain distributions as well as forging load are analyzed.
