齿坯锻造工艺的先进与否,不仅影响锻造生产本身,在相当大的程度上还决定了齿坯切削工艺的先进性,从而影响整个齿轮生产的成本。但工艺方法的选择往往又受设备条件的限制。模锻,是目前我国齿坯生产中较为先进的锻造方法。解放以后,我国锻压设备的生产有了很大的发展,大多数机械工厂已经配备了一定数量的锻压设备。但是多数为吨位较小的自由锻锤,例如广东几百个机械厂,只有三家工厂有模锻锤,五、六个工厂有一吨以上的自
Forging gear forging advanced technology or not, not only affects the forging production itself, to a considerable extent also determines the cutting edge cutting technology advanced, thus affecting the cost of the entire gear production. However, the choice of process methods are often limited by the conditions of the equipment. Forging, is the most advanced forging method in the production of gear blank in China. After the liberation, China’s forging production equipment has made great progress, most of the machinery factory has been equipped with a certain number of forging equipment. However, most of them are free forging hammers of smaller tonnage, for example, several hundred mechanical plants in Guangdong, only three have forging hammers, and five or six have more than one ton
