摘　　要：针对目前开式锻造档位齿轮坯工艺中耗能大,材料利用率低的问题,提出了一套新的闭式精锻成形工艺方案。利用有限元数值模拟软件DEFORM-3D分析了始锻温度、摩擦因子、压机速度对最大的成形载荷及成形质量的影响。并用优化的工艺参数进行生产试制,其结果与数值模拟吻合较好。Aiming at the problem of high energy consumption and low materials utility in open-die forging shift gear blank at present, a new closed-die forging process was introduced.The influence of initial forging temperature, friction coefficient and press speed on maximal forming force and quality was analyzed by the simulation software DEFORM-3D. And using optimized process parameters, shift gear blanks were trial-produced, results of which is correspond with one of the numerical simulation.
