内容简介：

汽车消音器的冲压工艺及模具设计摘 要本设计课题进行了拉深，翻边复合模具的设计。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、卸料板、定位装置等。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，本模具采用始用挡料销和固定挡料销。落料凸模内装有导正销，保证了工件上孔和外形的相对位置准确，提高加工精度。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。关键词： 复合模，冲孔，翻边，拉深AbstractThe paper is the banking or punching and bending composite die design. This paper briefly outlined the Stamping Die current development status and trends. The product is a detailed analysis and the identification process. Stamping die design in accordance with the general steps to calculate and design the sets on the main mold parts, such as: punch and die. Punch plate, feet behind the sales, market and other derivative is. Die-standard model planes need to choose suitable stamping equipment. Sign work on the parts and specifications will press for the necessary checking calculation. In addition, the die block used only with marketing materials and immovable the marketing materials. Blanking punch contents is a derivative sale, and guarantees the work piece and the shape of the holes in the relative position, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and mass production req
