Abstract：

“Hot forging + machining”is an effective way to manufacture spiral bevel gear.The final products performance depends on the quality of hot forging.The finite element software Deform-3D was used to simulate the hot forging process of spiral bevel driven gear blank.The metal flow law of forging process was studied.The results show that the stress and strain are great and the temperature is high in the ladder place because of the metal flows difficultly in the ladder place.The flow of metal can be better by improving die parameters. The relationship between initial forging temperature and forging energy consumption was studied.The results show that the forging energy consumption changes a little when the initial forging temperature is different.The numerical simulation on forging technology can be applied to improve die patameters and forging process parameters.
