应用有限元模拟和正交试验方法，分析了闭挤式精冲35钢直齿轮过程中凹模型腔锥面倾斜角度，主凹模圆角半径，反顶力，凸、凹模间隙对直齿轮齿面光亮带比例的影响。结果表明：各参数对直齿轮齿面光亮带比例的影响程度大小依次为凸凹模间隙，凹模圆角半径，反顶力和主、副凹模型腔倾斜角度。研究发现，优化参数后可以显著增大直齿轮齿面光亮带比例，光亮带比例可达96.7%。

In fine-blanking process,process parameters of fine-blanking and blank filling rate signifi-cantly influence the edge quality of the fine-blanking part. FEM simulation with ANOVA method was carried out to investigate the influence of the fine-blanked parameters(i. e. relative cutting clearance, counter force,corner radius of the main die,angle of the vice die cavity taper )on the light ratio of the closed-extruding fine blanking surface in the process of fine-blanking fine-pitch gear. The maxi-mum reduction of light ratio was about 96. 7% using the closed-extruding fine-blanking die with the optimization parameters,and the greater the blank filling rate is,the larger the light ratio is.
