Numerical simulation and experiment on precision forging of driven spiral bevel gear

摘要

In this paper, the numerical simulation of precision forging on driven spiral bevel gear was explored based on its physical simulation. The forming stage and the metal flow characteristic were analyzed; thereby the process of precision forging was designed. The material was 20CrMnTi and the equipment was friction press. The workblank of driven spiral bevel gear was manufactured successfully at 950°C∼1000°C. It was indicated that the numerical simulation of was reliable and effective. Moreover, the results would be beneficial to industrialization producing driven spiral bevel gears using precision forging.
