通过对阶梯形环件的成形工艺进行研究,运用理论依据初步设计了模具和工艺参数,利用动力有限元法对阶梯形内圈的冷辗扩成形进行了模拟分析,为毛坯和部分工艺参数的优化设计提供了依据。
Based on the correlative theory, the mould and the technique parameters are predesigned through study on forming process of step inner rings, and the finite element method is used to analyze the cold rolling forming of the rings, which provide the theoretical criterions for the optimum design of pre - parts and some technique parameters.
