中文摘要： 以61932号深沟球轴承外圈冷辗扩为例，运用Deform-3D V6.1软件rill rolling 模块进行数值模拟，分析了辗扩比和芯辊进给速度对环件破坏的影响，得出环件破坏与辗扩比以及芯辊进给速度之间的变化规律，为实际生产提供技术参考。
英文摘要：Taking the cold rolling of 61932 deep groove ball bearing outer-rings as an example, using the rill rolling part of Deform-3D V6.1 software, the numerical simulation was carried out, and the influence of the feed rate of the idle roller and the rolling ratio on the damage of the outer-rings was analysed, then the change law between the damage and the feed rate and the rolling ratio was obtained, which can provide a reference for production.
