500吨摩擦压力机螺母的方扣加工,按原来的老办法是一刀一刀地进行挑扣。不仅效率低,而且危险性大,劳动强度大,对机床导轨的磨损也极为严重,大拖板需要住复行程一千余次,电器正反起动频繁,很容易出毛病,有时中途还会出现扎刀现象。针对这种情况,我们学习并采用了河北省宣化机修总厂及有关单位的先进铣削方法,解决了这一难题。并在原有基础上,我们三结合小组,对刀杆长,吃刀发颤的弱点,又作了进一步改进。即在刀
500 tons of friction press machine nut buckle processing, according to the old method is to conduct a one-size-fits-all buckle. Not only inefficient, but also dangerous, labor-intensive, the wear on the machine guide rail is also extremely serious, large carriage need more than a thousand times trip trip complex, frequent positive and negative electrical start-ups, it is easy to problems, and sometimes there will be bar Knife phenomenon. In view of this situation, we have learned and adopted the advanced milling method of Hebei Xuanhua Machine Factory and related units to solve this problem. And on the basis of the original, we combined with three groups, the length of the arbor, the weakness of eating knife trembling, and made further improvements. That is the knife
