法兰盘冲压工艺与模具设计 摘要模具是工业产品生产使用的重要工业装备，它以其自身的特殊形状通过一些方式使原材料成型。现代工业生产中，由于模具的加工效率高，互换性好，节省原材料。 模具技术已成为衡量一个国家制造水平的重要标志之一。模具技术能促进工业产品的发展和质量的提高，并能获得极大的经济效益。模具是效益放大器，用模具生产的产品的价值往往是模具价值的几十倍、上百倍。 本设计运用冲压成型工艺及模具设计的基础知识，首先分析了工件的成形工艺及模具成形结构对制件质量的影响。介绍了冲压模具设计时要注意的要点，通过对制件进行工艺分析，可确定制件的成形加工用一套复合模即可。从控制制件尺寸精度出发，对冲压模具的各主要尺寸进行了理论计算，以确定各工作零件的尺寸，从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各重要零件的设计。 关键词：落料，冲孔，翻边 Fla
