| 摘要：冲压模具在实际工业生产中应用广泛。冲压模具的自动送料技术也投入到实际的生产中，冲压模具可以大大的提高劳动生产效率，减轻工人负担，具有重要的技术进步意义和经济价值。在这次设计中，首先我们使用UG软件的三文造型功能，对零件进行三文造型。对零件进行工艺性分析，绘制零件的二文和三文图，以加深对零件的理解。了解冲裁件、拉深件和成形件结构的工艺性。设定零件的工艺方案，比较工艺方案并确定工艺方案。计算毛坯的尺寸，计算冲裁次数，设定各步半成品的尺寸并绘出工序简图。计算各个工序的工作压力，设计并绘出模具简图，选取各个合适的零件。了解落料模、拉深模、整形模、切边模和冲孔模的特点和需要注意的问题，在模具简图的基础上进行模具结构工艺性分析，进行模具结构设计并选择冲压设备。7096 关键词：模具设计;冲压模具;工艺方案; 结构设计; Die design with a deck lights class into the ship Abstract : Punching die has been widely used in industrial. more Self-acting feed technology of punching die is also used in production, punching die could increase the efficience of production and could alleviate the work burden，so it has significant meaning in technologic progress and economic value. In this design, first we use the 3D sculpt function of UG to create 3D model of the part. During the procedure, the workpiece’s craftwork character is analyzed ,the workpiece’s 2-D drawing and 3-D mold are made, so that the workpiece can be better comprehended. Learn the structural craftwork character of the workpiece, so does the drawing and forming craftwork character. Make sure the workpiece’s craft project, compare them and make the final disicion. Calculate the size of the roughcast and select its shape. Calculate the times of the drawings , make sure the size of the semi-manufactured workpiece of every steps, and draw the working procedure’s sketch. Calculate the every working pressure, design and draw die’s sketch, select every appropriate parts. Comprehend every needed dies’ character and the issues that is needed to be payed more attention. On the base of the dies’ sketch ，the dies’structure is analyzed, and then go on designing their structures and selecting punch equipments.
