A Design in the Optimal Precision Forging Process about Half Axle Gears

摘要

The rigid-visco-plastic finite element model for the hot forging process of half axle gear was established,and the enclosed-die forging processes with different process parameters were simulated.As for the present forming process,the main influence factors on precision forming quality were identified and analyzed.The results show that proper die structure and cavity dimensions,suitable web thickness and position can improve material filling effect,which ensures gear tooth dimensions.
