导承的磨损程度取决于模锻时所采用的模具结构。在多膛模锻和偏心打击时,会加速导承磨损的过程。当导承磨损相当大的时候,密封垫的寿命则极剧减低。更换导承是一种繁重的工作,需要拆开气缸,从锤头内把锤杆打出来。在乌拉尔机器制造厂,3吨锤上比较大的导承和衬套都是用贵重的(?)C58-2-2猛铅黄铜制做的。当锤日夜生产时,其寿命一般不超过3个月。用钢制的导承和衬套的尝试没有达到予期的效果。这是由于锤工作时钢制锤杆和钢制导
The degree of wear of the guide depends on the die structure used during die forging. In the multi-chamber forging and eccentric blow, it will speed up the process of bearing wear. When the bearing wear is considerable, the life of the gasket is greatly reduced. Change the guide is a heavy work, you need to open the cylinder, the hammer from the hammer out. In Ural machines, the larger guide and bushings on the 3-ton hammer are made from the expensive (?) C58-2-2 fierce lead brass. When the hammer day and night production, its life expectancy is generally not more than 3 months. Attempts at using steel guide bushings did not achieve the desired results. This is due to the steel hammer rod and steel guide when the hammer is working
