Abstract：

The hot forging forming process of hub flange was simulated by finite analysis software Deform-3D, and the initial scheme of forming process was analyzed to determine the preforging and to finish forging scheme. However, for the problems of greater stress on surface of workpiece and the serious wear of final mould, the parameters in hot forging were optimized by Taguchi optimization design method. The results show that the stress of workpiece, mould wear and forming load are decreased and the forming quality of workpiece is superior when the deformation temperature is 1200 ℃, the mould temperature is 230 ℃, the deformation rate is 1.0 mm·s-1 and the frictional coefficient is 0.05. Thus, the influence sequence of each parameter on the quality of part and mould wear from strong to weak is the frictional coefficient, deformation rate, deformation temperature and mould temperature.
