摘要
为提高花键的成形质量,减小模具的试模成本,以小齿轮件花键部分建立CAE模型,分析花键在成形时不同定径带长度对偏移和充不满缺陷的影响。利用闭式冷挤压成形方法成形花键,根据速度场等值线云图判断花键是否有径向偏移趋势,依据模拟结果的可视化图和最小间距共同判断花键齿形是否填充饱满。结果表明,当定径带长度为3 mm时,成形的花键质量优。该研究结果对实际生产具有一定的指导意义。
In order to improve the forming quality of the spline and reduce the cost of die test,the CAE model of the spline part of the small gear was established,and the influence of the sizing belt length on the offset and underfill defects was analyzed.The spline was formed by the closed cold extrusion method,and the radial deviation trend of the spline was judged according to the contour map of the velocity field,and the full filling of the spline tooth shape was determined by the visualization of the simulation results and the minimum distance.The results show that the quality of the formed spline is the best when the length of the sizing belt is 3 mm.The results of this paper have a certain guiding significance for the actual production.
