高精度的冲头、导向销等冲模零件常常需要保持良好的润滑,一般是采用频繁地加注润滑油的方法,既麻烦,效果又不理想,还影响生产率的提高。为此,我们将结构作了改进。即在导向板上导向孔的周围开一个浅浅的凹槽、可以存油,见附图。在油槽中注满润滑油可以正常工作两班以上、效果很好。 High-precision punch, guide pin and other parts of the die often need to maintain good lubrication, the general method is to use frequent filling of oil, both cumbersome, the effect is not ideal, but also affect the productivity. To this end, we have made improvements to the structure. That is, a shallow groove is formed around the guide hole of the guide plate to save oil, as shown in the attached drawings. In the tank full of oil can work more than two classes, the effect is very good.
