Numerical Simulation for Cold Extrusion of Bevel Gear

Article Preview

Abstract:

A three-layers assembled cavity die and its technological measures were designed for cold extrusion forming for the bevel gear. Numerical simulation of the cold extrusion forming process was applied using Deform-3D software, load curve, velocity field, stress field and temperature field were analyzed, thus obtain the basic knowledge of the law of the bevel gear deformation. Subsequent targets for optimization were introduced, aiming to solve the remaining problems of the current cold extrusion forming. The accomplished work shows some significance in guiding how to design a die and its technological measures.
