Numerical Simulation and Numerical Profile Modification of Spring Back of Cold Forging Spiral Bevel Gear
Elastic deformation is a main factor of influencing the dimensional accuracy of the spiral bevel gear in cold forging.Cold closed-die forging process for spiral bevel gear was simulated by finite element software DEFORM-3D,and the variable law of the die elastic deformation and the spring back of forging were analyzed.According to the simulation results,using the inversing compensation method and the base circle modification method,the die cavity was beforehand revised to ensure the dimensional accuracy of the spiral bevel gear forging.
