Abstract：

Because the cold tear is easily generated in cold extrusion process of 6061 Al-alloy splines shell,the cold extrusion process is analysed directly and the finite element analysis software is utilized to simulate the forming.According to the simulation results,the cause of defect is found out and then an improving solution is put forward.Also,through the experiment,the surface treatment and lubricant method are improved.The practical production shows that this improvement can eliminate the defect effectively and the extrusion process is successful.
