Numerical Simulation of Cold Closed-die Forging of Bevel Gears

Cold closed die forging of differential bevel gears used for a car has obvious advantages not only in saving material and energy consumption, reducing production costs and increasing productivity, but also in being an excellent mechanical property and a long life period of products. The 3 dimentional FEM code DEFORM was successfully applied to simulate the cold closed die forging process of bevel gears used in Jetta car differential. The results of practical test showed that the technical design of cold closed die forging of bevel gears was reasonable,the die cavity design was accurate and the numerical simulation is effective.
