毕业设计（论文） 轿车内定位垫片零件大批量生产的冲压模具设计 姓 名： ： ： 系 别： 指导教师2016年5月摘 要 本次毕业设计题目为轿车内定位垫片零件大批量生产的冲压模具设计，轿车内定位垫片零件由钢板冲压加工而成，目的是设计并优化其批量生产工艺及部分冲压模具，体现了板类冲压零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，设计者重新学习并加强了冲压模具设计的基础知识，为设计更复杂的冲压模具做好了铺垫并吸取了更深刻的经验。 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。介绍了轿车内定位垫片零件大批量生产的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单工序模即可。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。 ：单工序模；冲压模具；模具设计ABSTRACT The graduation design topic for car positioning gasket parts mass production of stamping die design, car positioning gasket parts from sheet metal stamping processing. The purpose is to design and optimize the production process and stamping die, and reflects the requirements of sheet metal stamping parts design, content and direction, there are certain design significance. Through the design of the die parts, designers to learn and to strengthen the basic knowledge of stamping die design, for the design of more complex stamping die paves the way for and draw a more profound experience. Points forming this design using the stamping forming process and die design of basic knowledge, the first analysis of the workpiece forming process and die structure of parts quality. In this paper, we introduce the car positioning gasket parts mass production of stamping die design should pay attention to, such as nesting and feeding and discharging and the guide way, and from the control precision of parts as the starting point to discuss the main working parts clearance determination and cutting edge size and stamping force calculation, the parts for process analysis, can determine the workpiece forming process with a set of single process mode can be. From the mold design to the parts processing process and assembly process are detailed described, and should Use CAD to carry out the design of the important parts.
