提高拉深模具使用寿命和零件合格率的一种有效方法——干膜润滑拉深

A Method for Increasing the Life Span of Sheet Metal Drawing Dies and the Rate of Qualified Products——Dry membrane lubricant sheet-metal drawing

本文通过采用几种润滑剂分别进行不同的冷冲压拉深试验,测定了极限拉深系数等参数.实践及研究表明垫聚乙烯干膜润滑拉深对各种板材及不同的拉深成形方法都起到了提高其拉深性能的作用,对此还作了一些分析探讨,提出了相应的建议.

The Sheet metal drawing tests were carried out separately with several lubricants and he limit drawing coefficients were measured. In the test and practice, it shows that cushioning the dry membrane of polyethylene as the lubricant enhanced the performance of drawing with each kind of metal sheet and different drawing status. Analysis and studies were given to this.
