介绍了冷拉伸滚压成形原理,冷拉伸滚压是对阶梯轴类零件、杆类零件加工的一种新型加工工艺,其具有不需要对工件进行预加热、提高材料利用率、能耗低和生产率高等优点。采用大型有限元软件进行数值仿真分析,得出了应力应变分布情况,由此可以验证成形原理的合理性。
The principle of cold stretch rolling is introduced. Cold stretch rolling is a new processing technology for the machining of stepped shaft parts and rod parts. It has the advantages of no need of preheating workpieces, improving material utilization and energy consumption Low and high productivity advantages. Large-scale finite element software for numerical simulation analysis, the stress and strain distribution obtained, which can verify the rationality of the forming principle.
