| To study the closed precision-forging for shaft gear billet, a reasonable forming process was defined according to the special structure of the gear billet. The simulation analysis of closed precision-forging process was carried out by finite element analysis software. Corresponding physical experiment was carried out to validate the simulation results. Effective stress and strain distribution, metal flow pattern, temperature distribution and load change in the forming process were obtained through finite element simulation. The product made in experiment met the requirements and approximately agreed with the simulation results. In conclusion, gear billet made by closed warm precision-forging process meets the dimensional requirements. Therefore the process scheme is feasible. The simulation results are accurate and reliable and have a certain guiding function for actual production. |
