Numerical Simulation of Cold Heading and Extruding for Spiral Bevel Gear
This paper develops an opened forging and divided flow process for spiral bevel gears. By the help of rigid-plastic finite-element software DEFORM-3D, this paper designed cold-extruding part and concave die for bevel gear in the rear running gear of tri-motorcycle and simulated the forming process of cold-heading and extruding. On condition of guaranteeing shaping quality of teeth, the optimum diameter of die porthole was made sure by analyzing the effect of porthole size on volume of billet and plastic force. The experiment results show that the design parameter is reasonable and simulation results are helpful to the design of die.
