压缩机定子片冲压工艺及其模具设计 摘 要 电机定子是电机的重要部件，其质量对电机性能有直接影响。因此定子片成形模具的设计十分重要。电机定子片具有多槽孔的复杂结构，在生产中一定要保证其相对精度。定子片在使用中所需要的数量也较多，使用传统的单工序模进行冲裁必将造成高成本、低效益。因此本文采用多工步级进模对其进行冲裁。既保证了冲裁精度，又提高了生产效率。文中首先阐述了级进模的相关知识及发展前景，其次在详细分析冲裁工艺的基础上，重点讨论了毛坯优化排样、定距和定位方式、凸凹模结构以及固定方式等细节问题。最后采用CAD绘出级进模具的局部总装图。 关键词： 定子片，多工位，级进模 The Stamping Process And Mold Design Of Stator Piece Of Compressor ABSTRACT This paper studies the blanking technology of the motor stator vane and rotor vane and the design of blanking die. The stator vane and rotor vane are both indispensable components of a motor and their quality has a direct and important impact on the design of the motor. They both have such complex structures with a lot of slotted eye that its relative accuracy should be ensured during its producing. Since the stator and rotor vane are also needed in a great amount, it must results in high costs and low efficiency if the traditional simple press tool is used on blanking. So, in this paper, the author suggests that Multi-Step Progressive Die should be applied to the link of blanking so that the accuracy can be ensured and the efficiency can be enhanced at the same time. Firstly, this paper introduces some relative knowledge and the future development of Progressive Die. Then, some detailed problems, such as the black layout of blank, the way to fix spacing and position, the structure of top die and bottom die and the methods to fix them, are discussed carefully on the basis of a detailed analysis of the technology of blanking. Lastly, the setting drawing of the Progressive Die can be got by using CAD. Keywords: stator vane，multi-position ，Progressive Die 毕业设计（论文）原创性声明和使用授权说明 原创性声明 本人郑重承诺：所呈交的毕业设计（论文），是我个人在指导教师的指导下进行的研究工作及取得的成果。尽我所知，除文中特别加以标注和致谢的地方外，不包含其他人或组织已经发表或公布过的研究成果，也不包含我为获得 及其它教育机构的学位或学历而使用过的材料。对本研究提供过帮助和做出过贡献的个人或集体，均已在文中作了明确的说明并表示了谢意。 作 者 签 名：　　 　 　　日　 期：　　 　 　　 指导教师签名：　　 　 　　 日　　期：　　 　 　　 使用授权说明 本人完全了解 大学关于收集、保存、使用毕业设计（论文）的规定，即：按照学校要求提交毕业设计（论文）的印刷本和电子版本；学校有权保存毕业设计（论文）的印刷本
