本文采用几种润滑剂分别进行不同的拉深试验,测定了极限拉深系数等参数;研究表明,垫聚乙烯膜的润滑在拉深中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;对此还作了一定的分析探讨,并提出了相应的建议。
In this paper, several kinds of lubricants were used for different deep drawing tests, and the parameters such as ultimate drawing coefficient were determined. The results show that the pad polyethylene film lubrication has played an important role in the drawing and drawing of all kinds of sheet and different drawing forming methods Improve their drawing performance; also made some analysis and discussion, and put forward corresponding suggestions.
