Study on Cold Extrusion Process and Die for Vehicle Sleeve Gear with Spline
This paper mainly looks at the research on cold extrusion process and die of vehicle gear sleeve with spline, optimized the cold extrusion process of the part using FEM analysis, which gives us a theoretical basis for further exploration on the cold extrusion, and selecting optimum process parameters. The optimized results were verified by experiments and mass production. It analyzes the effect of the punch shape of gear container to metal flowing. The plastic flow could be controlled by the selection of the punch shape of gear container which reduced the resistance to deformation, and the gear profile was full without folding defects.
