现在介绍一种冲压用的新型润滑剂,它是含有多种化学聚合物的液体。这种液体生要是由己内酰组成。在生产加工中使用这种润滑剂,不但可降低生产成本,而且能提高生产效率。最近,我们根据国内外的资料作了一些试验,试验表明,这种新型润滑剂可大大延长模具的寿命,效果显著。试验情况如下:冲压加工件是螺母,加工材料为3毫米厚的20钢板。开 Now introduce a new lubricant for stamping, it is a liquid containing a variety of chemical polymers. This fluid is composed of caprolactone. In the production and processing of such lubricants, not only can reduce production costs, but also improve production efficiency. Recently, we made some tests based on domestic and foreign data. The experiments show that this new type of lubricant can greatly extend the life of the mold, the effect is remarkable. Test conditions are as follows: stamping parts are nuts, processing materials for the 3 mm thick 20 steel. open
