摘要：介绍了模具行程设计及其检查方法，先定义数据，设置模具行程数值组和闭合高度数值组；然后对定义的数据进行条件限制；最后确定相关零件的移动方式；对于检查方法，首先将定义数据输入Excel表中，单元格内根据压力机与模具行程之间的关系设置参数公式用以判断数据是否异常，并以异常颜色显示以起警示作用，确保行程设计无误，避免模具生产时出现行程类缺陷问题。

Abstract: It described the stroke design and checking method for progressive dies. Firstly, define data by setting die’s stroke value groups and shut height value groups. Secondly, limit the defined data based on the conditions. Lastly, confirm lifter moving way. Regarding the checking methods, it initially input aforementioned defined data into the Excel table, then set the parametric formula with relationship between press and die strokes in the table cells to determine whether data is accurate or not through expressions of highlighted colors of concerned issues.
Key words: progressive die; stroke design; shut height; feeding height; feeding mechanism
