摘　　要：轿车尾灯局部外凸,降低了整车的外观质量.以检测数据为依据,结合生产工艺确定了影响轿车尾灯缺陷的因素,通过改进模具压力加工的孔位、制件在整形时型面下限伸延,增加冲压件焊接夹具上受力等方法,进行了改进.Car taillights are locally convex outside,which reduce the vehicle ’s appearance quality.Based on testing data,combining with the production process,the factors that affect car taillight defects are determined.Through the improvement of hole made by mould pressure,the stretch of plastic parts surface,and the increase of stress on stamping welding jig,the car appearance can be changed.

关 键 词：局部外凸 检测数据 生产工艺 尾灯缺陷 改进
