摘 要

模具是制造业的重要工艺基础，在我国，模具制造属于专用设备制造业。中国虽然很早就开始制造模具和使用模具，但长期未形成产业。直到20世纪80年代后期，中国模具工业才驶入发展的快车道。近年，不仅国有模具企业有了很大发展，三资企业、乡镇模具企业的发展也相当迅速。冷冲压模具在现代工业中具有很重要的作用，其在机械制造、电子、电器 等各行各业中都有广泛的应用。用冷冲压加工方法可以得到形状复杂、用其它加工方法难以加工的工件，如薄壳零件等。冷冲压的尺寸精度是由模具保证的，因此，尺寸稳定，互换性好。
多工位级进模是在普通级进模的基础上发展起来的精密、高效、高寿命的先进模具。多工位级进模在不同的工位可以连续完成复杂零件的冲裁、弯曲、拉深、翻孔、翻边及其它成形等工序。主要用于生产批量大、材料厚度较薄、形状复杂、精度要求较高的中小型冲压件的生产。
本次毕业设计以N5汽车前门后视镜支承板级进模具设计为题，内容包括产品的工艺分析和设计模具的整个冲压模设计的流程。首先，从该产品的特点入手，通过进行工艺分析，确定该制件的加工流程，用一套级进模依次完成冲孔、裁剪、弯曲冲压、冲孔冲裁落料。阐述了本次支承板零件级进模具的整体结构特点及工作过程，应注意的问题和装配工艺性。重点分析了浮动托料导向装置和安全保护装置设计原理与过程。送料装置与安全保护装置的设计是本次毕业设计的难点和创新点，它在未来的模具发展中具有重要的实用性。

Abstract
The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. China although very already starts to make the mold and the use mold, but long-term has not formed the industry. Straight stabs 20 centuries 80's later periods, the Chinese mold industry only then drives into the development speedway. Recent years, not only the state-owned mold enterprise had the very big development, the three investments enterprise, the villages and towns the mold enterprise's development also quite rapid. Cold stamping die has a very important role in modern industry, machinery manufacturing, electronics, appliances and other industries. Cold stamping method can be complex shape, with other processing methods are difficult to process work pieces, such as the shell parts, etc. Cold stamping molds to ensure dimensional accuracy, therefore, dimensional stability, interchangeability.
Multi-position into modules are o-level into mode in the developed on the basis of precision, high efficiency, high life-span advanced mold. Multi-position into the mold in different location can continuously complete complex components cutting, bending, deep drawing, the hole flanging, flanging and other forming processes. Mainly for the production of batch big, material is very thin, complex shape, higher accuracy of small and medium-sized stamping production.
The graduation project Progressive N5 car front door mirror support plate mold design for the title, including the product of the process analysis and design of mold stamping die design process. First, starting from the features of the product, process analysis, to determine the processing flow of the parts, progressive die with a level in order to complete punching, cutting, bending stamping, punching and blanking. Described the overall structure and working process of the support plate part of the Progressive mold, should be noted that the assembly process. The focus of analysis of the design principles and processes of the floating material holding-oriented devices and safety protection devices. Feeding device and safety protection device design is the difficulty of the graduation project and innovation, it has important practical in the future mold development.
