摘要
主要介绍汽车安全气囊(40 L)气体发生器壳体(LD30)冷挤压成形工艺,并对模具结构、润滑条件等作了较为系统的分析。通过批量生产,该工艺可在20,30,60,80 L等不同容量气体发生器壳体生产中推广,有相当大的市场前景及经济效益。
This paper introduces mainly the cohl- extrusion forming technique for gas generator shell （LD30） in gasbag （40L）. It also analyzes systematically the die structure and lubricating conditions. This teehnique can be popularized in production of gas generator shell with different volume, such as 20,30,60,80 L, which will have a wide market and better economical,
