Numerical Simulation on Precision Forging Process for Spur-Gear with Large Module

Abstract:

The whole precision forging process of spur-gear with large module (module: 4) including warm forging, cold extrusion and cold sizing is analyzed. By using finite element method, cold sizing step of spur-gear basing on hollow-divided-flow method is simulated, the influenc of hollow diameter on the forging force and material flow is discussed in detail. Futher research shows that appropriate different tooth reduction is benefit to forming tooth profile without mechaning after forging. According to the research, to form such spur gear with module 4 and breadth 59mm studied in this paper, the hollow diameter should be 18mm and the tooth reduction should be 1.2mm. The necessary reference and basis to realize practical precision forging process of spur gear with large module is provided eventually.
