【Abstract】 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.更多还原
