摘　　要：通过对帝豪EC718顶盖冲压工艺分析,采用回弹补偿、过拉深和增大拔模角等方法,解决了顶盖内凹陷、回弹、刚性不足和装配不良等缺陷,保证了顶盖的外观质量和尺寸精度,节省了大量模具调试、焊装调试和总装调试时间,提高了生产效率。After analysis of the stamping process of EMGRAND EC718 roof,some forming problems of the roof such as depression,springback,insufficient rigidity,and poor assembly were solved by adopting methods of springback compensation,over drawing,and taper angle enhancement.Thus the precision and appearance quality of the roof was ensured,much time of die setting,welding and assembly adjusting was saved,and the production efficiency was improved.

关 键 词：回弹补偿 过拉深 拔模角
