摘　　要：汽车侧围它属于大包围的一种,是汽车的重要组成部分。所谓大包围——汽车车身外部扰流器,源自赛车运动。主要作用是:减低汽车行驶时产生的逆向气流,同时增加汽车的下压力,使汽车高速行驶时更加平稳。而引用到民用车上的大包围不再那么看重功能性,更强调的是外型的美观协调和个性化。在越来越追求个性的今天,外观上变化繁多、安装方便又最容易被看见的汽车改装件——大包围渐渐成为车主们首选的产品。论文主要以某款汽车外覆盖件侧围为例,简述了侧围冲压工艺方案的制定以及上下双活敞口拉延模具结构设计的工作原理。It belongs to a kind of large enclosure,It's an important part of the car.The so-called great encirclement of cars—external spoiler of automobile body,originated from motor sport.The main function is:to reduce the air flow generated by car while driving,and increase the downforce of the car,so that the car runs more smoothly at high speed.However,the big encirclement of civil vehicles does not attach so much importance to functionality,but to the beauty,coordination and personalization of appearance.In the pursuit of individuality,the car refit with various appearance,convenient installation and easy to be seen—big siege has gradually become the preferred product for owners.Is this paper,taking the side panel of a certain vehicle of automobile as an example,the working principle of the stamping process plan and the structure design of the upper and lower double movable open drawing die for the side panel is briefly described.
