2、设计同步，使设计方案到优化，从根本上保证产品质量。关键字：冲压模具 实体建模 CATIA-51-兰州交通大学毕业设计（论文）Abstract Modern mould industry is known for never declining.People begin to realize the great importance of mould in manufacturing and perceive that the technical standard of mould has been regarded as a symbol that indicate the lev
3、el of the manufacturing in a nation.Further more,mould determines the quality of the products,benefit and the capability of new products exploiting to a great extent. This paper mainly focuses on modeling and assembling the whole set moulds which are used to produce the sheathing of automobile glas
4、s riser by using the powerful function of CATIA in respect of modeling.Speedy conceptual design can be conducted by substantiality modeling system and their requirement and the programming restricts will be combined by the mathematic relation among different components in conceptual design.Basing o
5、n features,substantiality modeling and editing capacity help the designers changing and renewing substantiality by way of editing the dimension of substantiality features directly or other geometric editing and constructing techniques. For the sake of optimizing design plan,CAD and CAE can be used
6、simultaneously in designing,calculating analysis and designing can be conducted at the same time.so that the quality of the product can be ensured at the rock bottom. Key words:press tool solid modeler CATIA -51-兰州交通大学毕业设计（论文）目录摘要-1-1.绪论-5-2.零件的冲压工艺性分析-7-2.1零件的工艺性分析-7-2.2冲压工艺分析-7-2.2.1计
