The Research on the Simulation Metal Flow in Forging of Bevel Gears

Abstract:

The finished and preformed forgings of the rear lower arm are shown respectively, the shape of the rear lower arm is very complex.The tops of three branch arms are thick lumps and its central part consits of quite thin ribs.This forging is much more slender than the ordinary weldment made of steel plate and its weight is also lightened enormously.It seems that the forging is a limit example of pursuing the weight reduction.By taking great pains in forging scheme and die design,the forging is a success eventually.Simulation results indicate that the essential reason to form lap is the return when the material contacts the ends and the non-symmetrical return intensifies the depth of the lap.The lap was formed at the last moment.According to the simulation results, the dies was ameliorated. Thus,the qualified forging has been obtained eventually.
