摘要
介绍了气门弹簧座的冷挤压工艺和新型模具结构。模具采用自动返回顶料器,减少了辅助时间,提高了工作效率。
The working process for cold extruding of valve-spring base has been described, with a new die structure using ejector turning of itself. The jacking work bar of the ejector can return by itself with convenience to feed next blank hence the assistant time decreased and work efficiency improved.
