摘要: To reduce the difficulty of material filling into top region tooth in hot precision forging gears using alternative die designs, relief-cavity designs different sizes were performed on tooth. The influences conventional process and corner filling, workpiece stress, forming load utilization examined. Finite element simulation for forming, stress four was performed. further considered, optimal design determined. form trials ensured validity FE simulation. Tooth accuracy inspected by video measuring machine (VMM), which shows forged achieves level rough machining gear teeth. effects friction mode metal flow strain distribution also discussed.
