摘要：

在Deform-3D软件平台上建立了斜齿圆柱齿轮旋转精冲成形三维刚塑性有限元模型。基于Archard磨损模型对精冲过程进行了凹模模具磨损分析，得到了模具工作表面各点的磨损分布，确定了最大磨损发生区域，并与直齿圆柱齿轮精冲模具磨损进行了对比分析。通过单因素变量法，研究了反顶力、压边力、冲裁速度、凸凹模间隙、凹模圆角半径以及凹模初始硬度对模具磨损的影响关系。研究结果表明，磨损模型能准确预测旋转精冲过程中主要工艺参数与磨损之间关系，并从工艺设计方面提出了减小模具磨损的措施。

A reliable three-dimensional rigid-plastic finite element model for rotational fine blanking of helical gear was developed by the Deform-3D platform. Based on the Archard wear module, the wear analysis of die in the fine blanking process was carried out, and the wear distribution of points in the die working surface was obtained. Then, the maximum die wear range was determined, and the die wear characteristics of fine blanking of spur gears and helical gears were compared. Furthermore, the influences of ejector force, blank holder force, blanking speed, blanking clearance, fillet radius of bottom die, hardness of bottom die on die wear were studied. The results show that the relationship between die wear and process parameters are predicted by the above die wear model, and the solution that reducing die wear based on the process design is put forward.
