Abstract：

In this paper,an extrusion-forging process for a knuckle of Benz heavy truck is introduced,which includes four steps: Upsetting,extrusion,pre-forging and forging.FEM analysis of the extrusion-forging process for an automobile knuckle is also introduced.The simulation software DEFORM-3D is adopted,the rigid-plastic material model is used for forging and the forming process is supposed to be the isothermal forming.The change of the shape and size of the billet and forging,the distribution of the equivalent strain,and relationship between the load and distance are reported.The experiment result shows that the simulation result fits with the actual forming process very well.
