摘 要

　　　模具是现代工业生产中重要的工艺装备之一。在铸造、锻造、冲压、塑料、橡胶、玻璃、粉末冶金、陶瓷等生产行业中得到广泛应用。某些发达国家的模具总产值以超过机床工业的总产值在这些国家，模具工业已摆脱了从属地位而发展成为独立的行业。近年来，我国的模具工业也有了较大的发展，模具制造工艺和生产装备智能化程度越来越高，极大地提高了模具制造的精度、质量和生产率。

　　　本模具的主要作用就是落料和冲孔，该模具在设计时不仅要根据冲裁件的材料选择模具的材料，还要根据冲裁件的形状、尺寸和精度来确定模具的类型和冲裁的工艺方案。确定合理的冲裁间隙是本模具的重中之重，它不仅影响冲裁件的形状、尺寸和精度，还影响模具的使用寿命。在模具材料的选择时应注意材料的性能和强度。应尽量选择模具的标准件，这样不仅可以提高模具的寿命还可以缩短模具的制造周期。

　　　在模具设计时不仅要考虑要使做出的零件能满足工作要求，还要保证它的使用寿命。在本次设计中主要是考虑到它的实际工作环境和必须完成的设计任务，模架采用后侧导柱模架，凹模采用洞口形状凹模，这样可以一次完成全部的工序加工，在设计中要考虑到很多关于我所设计零件的知识，包括它的使用场合，外观等。通过这次的设计使我深深的体会到怎样才能把所学的东西更好的运用到实践中，设计过程中应注意的问题，使自己在冲压模方面有了更深更多的了解。

　　　模具的精度比较高在使用的过程中要合理的保养，发现问题要及时的修复，这样才能保证产品的质量，提高模具寿命。

Abstract

　　　Modern industrial production tooling is one of the important technological equipment. In casting, forging, stamping, plastic, rubber, glass, ceramic, etc, powder metallurgy industry production is widely used. Some developed countries with over the mould of machine tool industry total output value in these countries, mould industry have cut out the submissive position and become independent industry. In recent years, our country mold industry also has witnessed rapid development, mould manufacturing process and production equipment intelligentize degree is higher and higher, greatly enhancing the mould manufacturing precision, quality and productivity 

　　　This is the main function of the mould and punching blanking, the mould in the design not only according to the blanking pieces of material selection of materials, but also according to mould blanking pieces of shapes, sizes and precision to determine the types of dies and blanking process scheme. The determination of reasonable cutting clearance is the pinnacle of the mould, it not only affects blanking pieces of shapes, sizes and precision mould, still affect the service life. In the mold the choice of materials should be paid attention to when the properties of materials and strength. Should choose as far as possible, so that the standard mould can not only improve the service life of mould can shorten mould manufacturing cycle.

　　　In the mold design should be given not only to make a parts can meet the job requirements, but also ensure that its service life. In the design of the main consideration to its actual working environment and must complete the task, formwork design by side guide column formwork, concave die adopt hole shape dies.the, so can a complete the process in the design, want to consider a lot about what I design parts of knowledge, including its use occasions, appearance, etc. Through this design makes me deeply realized how to combine the use of anything better to practice, design process problems should be paid attention to, make oneself in progressive metal stamping has a deeper more about.

　　　The accuracy is higher in use process to reasonable maintenance, found that the problem should be timely repair, such ability assure product quality, improve die life.
