摘  要
本次研究的课题是山字型铁芯片的冲压模具设计，通过对该制件的外形结构、尺寸大小和材料性质的分析，初步确认采用冲压的工艺方法。对工件进行工艺及其结构的分析，可以确定此零件适合冲裁制造，并从产品结构工艺性分析，通其结构的特点延伸，具体分析设计出符合预先设计的程度。首先通过分析可知该制件结构比较简单且高度对称，厚度较薄，要求大批量生产，属于一般的冲压制件，然后进行相关工艺的计算来确定模具的设计，另外在设计过程中成本因素也应该作为一个格外需要注意的因素考虑进去。
该制件厚度比较薄，只有 ，所以在产品生产完成之后的卸料装置上需要注意这个参数来设计相关机构。另外，由于制件所需要的冲孔直径很小，所以设计的冲孔凸模强度是否足够也是需要格外注意的。本制件所要求的精度也不是很高，制件未注尺寸精度为 级。

Abstract
The study of the subject is e type iron chip of stamping die design, through to the appearance of the parts the analysis of the structure, size and material properties, preliminary confirm the stamping process. Analysis of workpiece process and its structure, suitable for cutting the parts manufacture can be determined, and from the product structural manufacturability analysis, through the mold structure characteristics, relevant parameters of molding part design, make its can meet the requirements of process parameters and production in advance. First of all, through the analysis on the structure is simpler and highly symmetrical parts, the thickness of the thinner, for mass production, belongs to the general stamping parts, and then the relevant process is calculated to determine the design of the mould, the other cost factors in the process of design should also be a need to be aware of all the factors into consideration.

The parts of thin thickness, only , so in the products production after completion of discharging device need to pay attention to this parameter to design the relevant institutions. In addition, because the punching parts need diameter is small, so the design of the punching punch strength is enough also need to be pay attention to. The parts required accuracy is not high, parts not note dimensional accuracy level .
