中文摘要：根据某规格汽车轮毂轴管零件的形状尺寸特点，分析了采用管坯模锻成形的可行性，对所制定的成形工步的聚料工步和终锻工步进行了模拟分析。结果表明，聚料工步设计正确；终锻成形的两种方案中顺序成形过程稳定，成形力有一定程度的降低，这将会改善模具的受力状况，提高模具的使用寿命。
英文摘要：According to the characteristics of shape and dimensions of a vehicle hub axle, the feasibility of die forging using tube-billet was analyzed, and the accumulating material step and final forging step were simulated. The results show that the design of accumulating martial step is right; in the two schemes of final forging, the deformation process in sequence is stable, the forming force is lower to some extent, which can improve the forcing situation of die work and prolong its life.
