摘　　要：温 -冷精锻综合成形是一种先进的金属塑性加工工艺 ,近年来在汽车工业中得到了广泛应用 ,并有取代传统的热锻成形的趋势。汽车后轴径是汽车工业中的典型锻件。本文分析了该零件的精锻加工特性 ,建立了其温 -冷精锻成形的有限元模型 ,根据有限元仿真结果确定了该零件的温Cold forgingand warm forging technology has progressed greatly in recent years. The combination of cold forging with warm forging is a new process used for manufacturing complex high quality components. In this paper, the precision forging process of a typical component (the rear axle spindle) in automotive industry, is studied with the aid of FEM simulation. With the FEM simulation results, the least required operations of this component is obtained, structure and dimensions of the die of each operation can be properly selected, and the stroke of each operation can be readily controlled.
