摘　　要：为优化模具结构,减少缺陷的产生,研究了轴承套圈反挤压过程中的应力、应变和载荷。以某轴承型号为例,使用Deform软件对轴承套圈反挤压过程进行数值模拟,比较了不同的冲头倒角和料芯厚度与冲头载荷之间的关系。结果显示,冲头倒角在4mm时载荷最小,料芯厚度小于7.5mm时冲头载荷显著增大。实际生产结果表明,使用模拟参数设计的模具结构可以获得优良的锻件,因此,该方法可以为模具参数设计提供依据,尤其是对不锈钢这类容易出现锻造裂纹的材料更具参考价值。For optimizing the mold structure and reducing defects,stress,strain and load for the anti-extrusion process of bearing ring were presented.Taking a model as an example,Deform was used for numerical simulation.Relationship between different punch chamfers,thicknesses of material core and punch load were compared.The results indicate that punch load can obtain the minimum value when chamfer is of 4 mm and can be increased significantly when the thickness of material core is less than 7.5 mm.Actual production show that using simulation parameters to design mold can get a good forgings,so this method can provide a reference for mold design,especially more useful for the stainless steel which is easy to have forging cracks.
