摘　　要：针对传统前轴生产工艺易导致产品局部强度下降,生产效率低下的问题,提出了前轴局部精整成形的新工艺。设计了局部精整模具,并应用有限元数值模拟方法分析了局部精整成形过程中的充填情况、成形载荷以及弯曲变形的规律。分析结果表明:在新的工艺及模具结构下,锻件填充情况良好,成形载荷适当。这些为生产工艺的制定及精压设备的选型提供了一定的理论参考。Aiming at the local strength degradation and low productivity of the traditional production process for fore-axle, the new local finishing process was proposed. The finishing die was designed. According to finite element numerical simulation method, the filling state, load prediction and bending deformation of the local finishing process were obtained. The results show that the new process and die structure can ensure the filling quality and fitting load. Those provide theoretical reference for production process and equipment selection.
