黄河科技学院毕业设计（论文） 第 PAGE \* MERGEFORMAT 5 页 拖车消声器筒体封头多工序复合模具设计 摘??? 要 本设计进行了落料、冲孔、拉深、翻孔复合模的设计。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、垫板、凹模固定板、卸料板、挡料销、定位销等。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，本模具采用圆形挡料销进行挡料。模具的冲孔和落料凸模分别用不同的固定板固定，便于调整间隙；冲孔凹模和落料凹模则采用整体固定板固定。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。 关键词： 复合模，校核，冲孔，落料，拉深 The design of the complex multi-die process of trailer muffler cylinder head Author : zhang fu lin Tutor : wang ai zhen Abstract ?The design of the blanking ，unching，rawing and hole flanging composite modulus design. This paper briefly outlined the Stamping Die current development status and trends. The product of 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 ，die，convex fixed formwork，Plate，fixed die plate，discharge board，expected sales block，pin and so on . Die-standard model planes, to choose a suitable stamping equipment. Design work on the parts and specifications will press for the necessary checking calculation. In addition, The mold is expected to adopt a circular block to block marketing material. Punch and Die blanking punch were different plate fixed to facilitate adjustment gap; Punch and Die blanking die is used overall fixed plate. Blanking punch contents is a derivative sales, and guarantee the workpiece and the shape of the holes in the relative position accurately, improve processing accuracy. So the structure is designed to ensure reliable operation of die stamping products and mass production requirements.
