机罩盖板冲压模具设计【毕业论文+CAD图纸全套】.doc

机罩盖板冲压模具设计 摘 要 本设计进行了落料、冲孔连续模的设计。冲压工序的选择是经查阅相关资料和对产品形状仔细分析的基础上进行的；冲压模具的选择是在综合考虑了经济性、零件的冲压工艺性以及复杂程度等诸多因素的基础上进行的；产品毛坯展开尺寸的计算是在方便计算但不影响模具成型的前提下简化为所熟悉的模型进行的。文中简要概述了冲压模具目前的发展状况和趋势。对产品进行了详细工艺分析和工艺方案的确定。按照冲压模具设计的一般步骤，计算并设计了本套模具上的主要零部件，如：凸模、凹模、凸模固定板、垫板、凹模固定板、卸料板等。模架采用标准模架，选用了合适的冲压设备。设计中对工作零件和压力机规格均进行了必要的校核计算。此外，本模具采用挡料销挡料。各部设计保证了工件上孔和外形的相对位置准确，提高了加工精度。如此设计出的结构可确保模具工作运行可靠和冲压产品大批量生产的要求。最后对模具结构与压力机的匹配进行了校核.并用utoCAD绘制了一套模具装配图和零件图。 关键词： 倒装复合模，冲压工序冲压模具ABSTRACT The design of the blanking, punching die design. Stamping process is the choice of the available relevant information and a detailed analysis of the shape of the products on the basis of; stamping die option is considered in the economy, parts of the stamping process and the complexity of many factors, and so on the basis of; Products rough start calculating the size is calculated at a convenient but does not affect mold forming on the premise familiar to simplify the model. In a brief overview of stamping die present state of development and trends. The product of a detailed analysis and the identification of the programme. Stamping die design in accordance with the general steps to calculate and design of this set of mold on the major components, such as: punch, die, punch fixed panels, Dianban, fixed-die, unloading plates. Die-standard model planes, choose the unappropriate stamping equipment. Design work on the parts and specifications are to press the necessary check calculation. In addition, the mold used before expected sales block by block material. Ministries designed to ensure the workpiece and the shape of the hole on the relative position of accurate and improve the accuracy of processing. So the structure can be designed to ensure that the work of die stamping products and reliable operation of mass production requirements. Finally, the structure and presses the mold match was checking. AutoCAD drawing and using a mold assembly and parts plans. KEY WORKS: flip-molding，stamping process，stamping dies
