本文介绍利用测试总拉深力和极限拉深比的实验方法,研究拉深用润滑剂的粘度和凹模圆角半径对拉深成形工艺的影响.从实验中发现具有相同成份添加剂的润滑剂,只要提高基础油的粘度即可改善其拉深性能.这一结果对实际生产过程中具有一定的参考价值.
This article describes the use of test the total drawing force and the ultimate draw ratio of the experimental method to study the viscosity of the drawing lubricant and the die radius of the radius of the impact on the drawing process.From the experiment found that with the same ingredients additives lubricants , As long as the viscosity of the base oil can be improved to improve the drawing performance of the actual production process has a certain reference value.
