汽车冲模水冷延时系统的应用研究与实践

Application research and practice of water-cooling delay system for automobile stamping die

阐述了水冷延时系统在汽车冲模中的应用与实践,解决了车身安全结构件在传统冲压工艺中成形困难、塑性变形不彻底等问题,通过压缩空气和电磁阀控制,驱动带有水冷系统的延时氮气弹簧实施延时压边拉深成形,制件成形效果良好。

The application and practice of water-cooing delay system in automobile stamping die were described,it solved the problems such as difficult forming and incomplete plastic deformation of body safety structure parts in traditional stamping process.By controlling with compressed air and solenoid valve,the delayed nitrogen gas spring with a water-cooling system was driven to implement delayed drawing forming with blank holder.The forming effect of the parts was good and the promotion value was high.
