Abstract：

For the dislocation，folding and other issues occurred during the forging process of steering curve arm, the causes were studied by combining the experiment with the finite element analysis. Then the plan combined final forging with correction in original process was put forward，the parting surface of final forging was confirmed and changed into V-shaped parting surface. The improved process plan was simulated. The result shows that a qualified product can be produced by the improved process, the difficulty of locating for blank is solved during the correction process，and the scrap ratio of product and the amount of workers needed are reduced. The experimental test shows that in the improved process，the maximum pressure of final forging is reduced to 9000 kN，one step is saved without changing the equipment, the productivity is improved，and the energy consumption is decreased.
