摘    要:简要地介绍了环件冷辗扩原理、冷辗扩工艺、冷辗设备、加工过程控制参数、模具寿命及有限元模拟技术的现状和发展,并指出了环件冷辗扩还缺乏精确而系统性的研究,弹塑性有限元研究才刚刚起步,通过模拟来优化加工过程参数在国际上也几乎没有公开发表的文献。因此,应该从理论、有限元模拟、材料、设备、热处理、模具等多学科联合攻关研究,才能使我国的环件冷辗扩技术跃上一个新的台阶。

关 键 词:环件  冷辗扩工艺  冷辗扩机  冷辗扩控制  冷辗扩模具

Abstract:The current status and the development of the cold ring rolling theory, eold ring rolling teehnology,cold ring rolling equipment, production process control parameters, tooling life and finite element simulation teehnology are briefly introduced in this paper. It points out that there is no accurate and systematical research for the cold ring rolling and the elastic-plastic finite element analysis of eold ring rolling process is just starting. However, in our country the research of finite element simulation for cold ring rolling is blank. At the same time, there are few international publications which are related to optimizing the process parameters by simulation. Therefore, our cold ring rolling technology will jump to an advanced level only by the combined research of the theory, finite element simulation, raw material, equipment, heat treatment, tooling and other subiects.
Keywords:ring   cold ring rolling technology   cold ring rolling mill   cold ring rolling control   cold ring rolling groove
