摘　　要：以某型种树机减速器用齿轮坯为研究对象,利用DEFORM-3D有限元数值模拟软件对其精密塑性成形过程进行仿真,分析了预热温度摩擦因子、压机工作速度对模具最大磨损量的影响。在预热温度300℃,摩擦因子0.3,压机工作速度50 mm/s的情况下进行了模具生产试制。试制发现,模具磨损量较小,锻件成形质量良好,模具寿命较长。In this paper,the gear blank of a tree machine reducer is taken as the research object.The influence of die preheating temperature,friction factor and press speed on the maximum wear rate of the die in the forming scheme is analyzed by finite element numerical simulation software DEFORM-3D,The preheating temperature of the die is optimized to 300℃,the friction factor was 0.3,and the press speed was 50 mm/s for trial production.The wear rate of the die is small and the forgings are forged.The forming quality is good and the die life is improved greatly.
