摘要：随着汽车、电子电器、通信、医疗器械、造船和航天工业的发展，各行各业对形状复杂的零件的需求的增加，传统的单工序模已经很难满足制造要求。在这种需求的推动下，级进模开始受到重视。本次设计，就是以电脑光驱托架为设计对象，通过对工件的分析以及利用三维制图软件设计出相应的级进模。在本次设计中，会先利用UG绘制出零件的三维模型，然后进行级进模的工艺分析，接着开始级进模最重要的排样，在排样过程中首先需要充分考虑零件的成型过程，如冲裁，弯曲，拉深，胀形等的先后顺序，其次还需要考虑到板料的前进是否受阻，直至最后切下成型工件。排样结束之后就是设计模具的结构，通过查阅相关的书籍选择合适的模具零部件，通过Pro/E画出模具的三维模型，然后设计出爆炸图。最后一步就是利用Pro/E中的模具三维图导出二维图，在CAD中进行修改，并画出一些比较复杂的零部件的二维图。在设计结束时，做出三维模型图，爆炸图，装配图，零件图以及设计说明书。

Abstract：With the development of automobiles, electronics, communications, medical devices, shipbuilding and aerospace industries, the demand for complex parts varies from industry to industry, the traditional single-process mode has been difficult to meet the manufacturing requirements. In this demand, driven by progressive die began to be taken seriously. In the development of computer technology, the development of progressive die is also more systematic. The most typical is the sheet metal pieces of progressive die design, industrial development required sheet metal structure more and more complex. The design, is to computer optical drive bracket for the design object, through the analysis of the workpiece and the use of three-dimensional mapping software to design the corresponding progressive die. In this design, we will first use UG to draw the three-dimensional model of the parts, and then the process of progressive die analysis, and then start the progressive die of the most important, in the nesting process first need to fully consider the parts of the molding process , Such as punching, bending, drawing, bulging, etc., followed by the need to take into account the progress of the sheet is blocked until the final cut into the workpiece. After the end of the layout is the design of the mold structure, by consulting the relevant books to select the appropriate mold parts, through Pro / E to draw the mold of the three-dimensional model, and then design an explosion map. The last step is to use Pro / E in the mold three-dimensional map to export two-dimensional map, in the CAD to modify, and draw some of the more complex parts of the two-dimensional map. At the end of the design, make three-dimensional model maps, explosion maps, assembly drawings, parts drawings and design specifications.Keywords:
