摘　　要：详细介绍了延时氮气弹簧系统的工作原理及在汽车冲模中的应用,机床滑块回程时氮气弹簧对制件的局部冲击进行有效控制,使氮气弹簧不回弹或者微小回弹,延时回程,具有保护制件及延长模具使用寿命的作用。The working principle of delay nitrogen spring system and its application in stamping dies for automobiles were presented in details. The local impact of nitrogen spring on the part in the return stroke of machine tool slider is effectively controlled, in which the nitrogen spring does not springback or has just a little springback and delayed return. The application protects the product and extends the die service life.
