汽车挡泥板复合冲压模设计
摘要
模具是工业生产中重要的工艺装备，是国民经济各部门发展的重要基础之一。复合模是一种复杂、精密的冲压模具，它具有高效率、高精度和高寿命等优越性，适用于各种冲压行业的自动化生产。复合模涉及冲压成形理论、冲压工艺、模具设计与制造以及模具材料中的许多关键技术。板料的冲压成型是一种重要的金属加工方式，被广泛地应用工业生产领域中。模具是工业生产的基础工艺装备。用模具生产制件所具备的高精度、高复杂程度、高一致性、高生产率和低消耗,是其他加工制造方法所不能比拟的。
对汽车挡泥板进行冲裁工艺分析并确定冲裁方案，说明了模具主要零部件的设计和选用。以Solidworks为平台，利用三维参数化设计与建模技术，对汽车挡泥板的冲压模具进行三维参数化造型设计，可以根据需要改变模具的尺寸；进行虚拟装配，可以直观地观察和分析模具的结构以及零件的相互位置关系；加快了产品开发速度，提高了产品开发效率，缩短了产品开发周期。

Abstract
Mould& Die is important technical equipment in industrial production. It is also one of the most important developmental foundations for all departments of country economy. The progressive die is a kind of complex and precise forming die. It possesses many advantages such as high efficiency, accuracy and long life. The sheet metal stamping forming is important metal processing methods have beenwidely used industrial production areas. Mold is the basis for industrial production processes and equipment. Mold production ofwork pieces by the available high-precision, high-complexity, high consistency, high productivity and low consumption, other manufacturing methods could be compared.
Blanking process analysis of fender is completed and blanking proposal is decided, and designing and selecting of main parts of die are showed. Based on Solidworks, three-dimensional parameterization molding designing for fender is completedwith technology of three-dimensional parameterization designing and model building, and dimensions of die can be changed as required; byvirtual assembly, structure of die and relation of mutual alignment can be observed and analyzed directly; the product rate of development is accelerated and product development cycle is shortened.
