摘 要针对冷冲压技术在零件制造行业上的运用，根据零件制造实例，借鉴已有的设计 方案，研究出完善模具设计过程。首先，明确一点，零件是本来就有的，设计的是对 模具进行设计而不是改善零件的设计。此次论文主要研究的内容是，冲压工艺的分析 和制定，冲裁件的工艺性分析，包含了冲裁件的尺寸、形状、精度、表面粗糙度和毛 刺等，还有冲裁间隙的选取，凹凸模刃口尺寸的设计计算、压力机的选取，冲裁模标 准零件的选用，其中包括，模架、模柄、冲模导向装置等等，当然也还包括弹簧及橡 胶弹性件的选取，整体模具结构的选用等等。模具的装配和模具的调试模具设计的最 后一个环节，可是同样的的是，它也是最为重要的环节。由于在设计的过程中，模具 上的零件大多采用标准件，这就带来了另一个问题，就是标准件的选取问题，选取标 准件时，需要非常的细致，根据实际情况来选取，而且技术参数也要取得相对合适。 互换性是模具产品设计的重要依据，通过本论文准确的根据已知参数，尽快完成设计 工作，提高设计质量，缩短生产周期。论文实现的内容就是，能够在独立的条件下， 能够让人清晰的明白模具的整套设计流程。并且这个论文能够用来指导模具的制造， 设计无明显缺陷，本文的设计过程无错误，能够作为模具设计的模板。绘制的零件图、 装配图能够完成零件的加工，装配图能够直接指导工人实现模具的装配。84917

Abstract According to the application of the cold stamping technology in the parts manufacturing industry, the design process of the mould is studied by drawing on the existing design scheme。First of all, it is clear that the parts are already there, the design of the mold is designed to improve the parts of the design。This paper mainly studies the content, analysis of stamping process and formulation, the blanking process analysis, contains the blanking piece's size, shape, precision and surface roughness degree and burr and clearances of the selection, design and calculation of the size of the embossing edge, selection pressure machine, punching blanking die standard parts selection, including, mold, die shank, die directs device and so on, of course, also includes the spring and a rubber elastic element selection, overall mold structure selection, and so on。The last part of the assembly and debugging of mold design and mold mold, but the same is that it is the most important part。 Because in the process of design, mold parts mostly using standard parts, which brings another problem, is the standard parts of the selection, selection of standard parts when the need to be very careful, according to the actual situation to choose, but also to obtain appropriate technical parameters。 The relative interchangeability is an important basis for die design, this paper accurately according to known parameters, complete the design work as soon as possible, improve design quality, shorten the production cycle。 The content is able to separate under the condition, can let people understand the whole mold design process clear。 And this paper can be used to guide the design of mould manufacturing, without obvious defects, the design process without error, can be used as a mold The design of the template。 Drawing the parts diagram, assembly drawing to complete the parts of the processing, assembly drawings can directly guide the workers to achieve the mold assembly。
