毕业设计（论文)-托板冲压成型级进模设计(完整图纸）.doc

摘要 模具冲压生产是一种先进的机械加工制造方法之一。冲压加工生产出的零件具有质量高，使用性能好的特点。因此在生产中得到了广泛的应用。 托板是机器中的常用零件，现在已大批量生产。主要作用是托起机械设备中各个元件，起到固定和增加散热的作用！具有制造简单，成本低，耐腐蚀等特点。并且能根据具体情况具体设计形状。方法是分两道工序完成，一个冲孔，一个落料。设计一个安全，高效，高精度，低成本的模具具有很现实的意义。 在这次设计中，选用了级进模具，将以往简单分散低效率的冲压转变为一次加工成型的自动生产过程，从而使得劳动生产率大幅度提到。 关键词：模具；冲压；托板；级进模具；劳动生产率 全套CAD图纸等，联系153893706 Abstract It is one of the kind of advanced machining manufacturing approaches that the mould is stamping. Having quality high to process the part stamping, the characteristic with good serviceability. So has gotten extensive application during production. Supporting the commonly used parts of machinery is now mass production. The main role is picks up in the mechanical device each part, plays function which fixed and the increase heat release! Supporting has the manufacture simply, cost low, is anti-corrosive and so on the characteristic. And it can act according to the specific　situation design shape. Work processes completed in two ways, one is piercing, the other one is shearing. Design a safe, efficient, high-precision, low-cost instrument with a very realistic sense. Here I would like to design a class into modules to complete the production of spare parts. During this design, have been selected for compound mould very much, will disperse the inefficient punching automatic production process of changing processing shaping into briefly in the past. This make the labor productivity improve by a large margin.
