Simulation Study on Cold Extrusion Forming Process for Axle Housing with Taperhole

The numerical simulation method was applied to research the cold extrusion process for axle housing with taperhole.The law of metal flow in the forming process of the parts was investigated.The metal flow and its splite-flow were reasonable and the parts were without any forming defects in the whole process.The results show that the cold process is reasonable and feasibility,and can provide reference for similar part forming.
