八、料叉在中、小型锻造车间里,装炉、出炉是件很辛苦的工作。现在配有锻造出、装炉机械的工厂还很少,用桥式吊车和料叉解决坯料的出、装炉问题仍是目前的主要生产方式。料叉是挂在吊车转链上当做杠杆使用的,因而要有较好的强度。为了与被装、出炉坯料的重量相平衡,料叉本身也要有足够的重量。料叉最好是整体锻造出来的,如图28所示。这种料叉的锻造工艺过程 Eight, fork in the small forging shop, loading furnace, baked is a very hard work. Now with forging out, loading furnace machinery factory is still very small, with bridge crane and fork to solve the billet out, loading furnace is still the main mode of production. Fork fork is linked to the crane chain as a lever to use, so have better strength. In order to balance the weight of the stock being loaded and unloaded, the forks themselves must have sufficient weight. The forks are best forged as a whole, as shown in Figure 28.
