A Design in The Optimal Precision Forging Process about Transmission Shaft Flange Yoke

摘要

The rigid-visco-plastic finite element model for the hot forging process of transmission shaft flange yoke was established, and two forging schemes of different male die shapes were simulated. As for the present forming process, the forming defects were indentified and analyzed. Based on the simulating results the decision-making process was obtained, and a preforming die and a final forming die with proper structures and longer life were designed. The transmission shaft flange yoke part produced by this process is excellent in dimension tolerance and mechanical property. This process is profitable reference for producing the similar type of forks with complex shape.
