我厂现有一台3t蒸汽自由锻锤,其中主要的摩擦副锤头与导向滑板以前是采用人工涂沫11~#汽缸油进行润滑的。但是, 由于锻件的辐射热烘烤,涂上的润滑油很快就被烤干,所以两者经常处于干磨状态,致使配合间隙日渐增大,从而引起锤头导向不良,打击锻件时摆动很大。这样不但影响锤身的连接刚性,使各部连接螺栓容易松动,而且严重时会引起锤杆折断,增加了备件消耗和设备检修停工。鉴于上述情况,1989年我们与四川省自贡
Our factory now has a 3t steam free forging hammer, the main friction pair hammer and guide skateboarding is to use manual coating 11 ~ # cylinder oil for lubrication. However, due to the radiant heat forging bake, coating the lubricating oil is quickly dried, so the two are often in the state of dry grinding, resulting in increasing with the gap, which led to poor hammerhead orientation, when the fight forging swing Big. This will not only affect the rigidity of the hammer body connection, so that the various parts of the bolt loose easily, and in severe cases will cause the hammer rod broken, increased spare parts consumption and equipment maintenance downtime. In view of the above, we worked with Zigong, Sichuan Province in 1989
