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。

Design of Progressive Die for rotor Plate
Abstact: This design is mainly designed for the progressive die of the motor rotor blade, because the rotor used by the motor is formed by the superposition of a number of rotor blades. Therefore, the demand for the rotor isvery large, the production efficiency of the ordinary stamping die is notvery high, and the progressive die has high production efficiency, long life and good quality. The mass production of parts, stamping quality is reliable and stable. Through the analysis and process of the rotor parts diagram analysis,we can know that the inside and outside of small size parts, coaxiality demanding, high precision, large output, using progressive die production. Because the size is small, the layout is the layout of the first mock exam out of three pieces In order to minimize the effect of the error of the step on the precision of theworkpiece, the next job is to drop the material after the hole iswashed. Because the precision of theworkpiece is higher, the guiding precision of the die is higher, so the guide pillar of the die is guided by a rolling guide, because some parts of the progressive die are easily damaged. Therefore, parts of each station are assembled and processed in a combined form.
This article is about a simple parts stamping process analysis, through analyzed the stamping, the blank decided to adopt multi-station progressive die processing in this paper, the design of progressive die and some of the major parts and components, and the paper detailed introduces the blanking process, including blanking, punching, layout, etc. The structure design of the mould and the dimension calculation of each part, and using CAD to draw the parts drawing and integral assembly drawing ofvarious non-standard parts.
