铜垫片倒装复合模设计 【摘要】：随着模具的迅速发展，在现代工业生产中，模具已经成为生产各种工业产品不可缺少的重要工艺设备，为了提高学生在模具设计方面的能力，以满足社会的要求，学校安排了毕业设计，这次毕业设计是在学习完冲压模具设计、机械制图与AUTO CAD、工程材料等课程的基础上进行的，是对大学所学知识的一次综合应用，也是对我所学知识的回顾与检查。通过实例，我首先对冲压件进行了分析，分析该零件的尺寸精度得出用一般精度的模具即可满足零件精度的要求，再从零件的形状、尺寸标注及生产批量等情况看，选择了冲孔落料的方案。这里主要探讨的是根据工件自身的特点，，设计中还要考虑到它的实际工作环境和必须完成的设计任务。因为由模具生产的产品主要是成批生产，而且模具可以保证冲压产品的尺寸精度和产品质量，所以模具的设计与制造主要考虑到模具的设计能否满足工件的工艺性设计，能否加工出合格的零件，以及后来的维修和存放是否合理等。在本次设计冲孔落料复合模中，不仅要考虑使做出的零件能满足使用要求，还要保证模具的使用寿命。 of the aspects ability that the exaltation student design in the molding tool request, school, with satisfy the society to hold the graduate design, and graduate the design this time is in the study over to wash to press the molding tool the design, machine graphics and AUTO the CAD, engineering material the foundation of course etc. Molding tool that to go forward a line of, is to the knowledge that university learn of synthesize the application for a times, and also review my learned knowledge and check. pass the solid example, I right first wash to press a size accuracy for proceeds analysis, analyzing that spare parts to get to use the general accuracy to then satisfy the request of the spare parts accuracy, again from the spare partss shape, size the mark note and produced the batch quantity etc. The circumstance to see, choose to hurtle the bore the project. Primarily study here of is a design mission for characteristics for oneself,, design inside still wanting in consideration of its actual work environment with must completing according to the work piece. Spare parts that because product that produce is from the molding tool primarily is criticize to produce, and the molding tool can guarantee the size accuracy of the product of washing to press the design and product quantity, therefore the design and the manufacturing of the molding tool is primarily in consideration of the molding tool can satisfy the craft of the work piece the design, and can process the qualified spare parts of, and laterly maintain with depo
