转子片级进模的设计 摘要：本次设计主要是设计电动机转子片的级进模，因为电动机使用的转子是由多片转子片通过叠加的方式，才形成转子的，因此对转子片的需求量很大，使用普通的冲压模的生产效率不是很高，级进模具有生产效率高，寿命长，质量好，适用于制件的大批量生产，冲件质量可靠，稳定等特点。通过对转子片的零件图的分析和工艺性分析，可以知道，制件的内外尺寸较小，同轴度要求严格，精度要求高，产量较大，采用级进模生产。因为制件尺寸小，排样是采用一模出三件的排样方式，考虑到尽量减少步距的误差对制件精度的影响，在冲转子孔后，接着下一工位就是落料。因为制件的精度要求比较高，所以对模具的导向精度要求就更高了，所以模具的导柱采用滚动导向的导柱进行导向，因为级进模的有些零件容易损坏，所以，各个工位的零件是采用组合形式进行装配和加工的。 本篇文章是对一个简单的零件进行冲压工艺分析，通过对毛坯进行了冲压分析，决定采用多工位级进模加工文中，设计了级进模和一些主要的零部件，并且文中详细的介绍了冲裁工艺，其中包括落料、冲孔，排样等。模具的结构设计与各个零部件的尺寸计算，并且运用CAD画出了各个非标零件的零件图和整体装配图。 关键词:冲压工艺、冲孔、落料、多工位级进模 Desig
