摘要

In order to improve the surface quality of high-speed cold rolling lines technology,the cause of residual height of tooth profile of the theoretical analysis and analytic calculation and geometric simulation are studied.The basic principle of high-speed cold rolling technology are briefly discussed,the factors that influence the residual height of the block side teeth are analyzed.The model for residual height is established by calculating the residual height of flank.With MATLAB,the effects of various factors on the residual height geometry are studied.On the self-developed equipment for cold rolling tooth block cold test,the flank residual height were measured so as to verify the correctness of analytic geometry and accuracy reliability.%为提高高速冷滚打成形技术的表面质量,对高速冷滚打齿块侧面残余高度的成因进行理论分析和仿真计算.简述高速冷滚打成形技术的基本原理,分析齿块侧面残余高度的影响因素;对齿块侧面残余高度进行数学几何建模计算,得出残余高度的数学关系式;并通过MATLAB对齿侧面残余高度进行几何仿真,研究分析主要成形参数对其影响.在自主开发的冷滚打设备上进行齿块冷滚打试验,对齿侧面残余高度进行测量,验证了几何解析的正确性和精度可靠性.
