(一) 我們鍛造图1的齿輪,原先是在0.5吨蒸汽錘上进行的。由于錘子冲击力不够,只能把齿輪大阶台和內孔鍛出。每个齿輪要下料33.3公斤。在节約金屬材料的号召中,同志們想出一个办法,利用0.4吨空气錘上已經作廢的上下錘头,改制成如图2的錘头和模座;另外把齿輪改成图1乙那样,并且按齿輪下半截的几何形狀配制一个垫模。經过这样的改进,在0.4吨空气錘
(A) We forged the gear of Figure 1, originally on a 0.5 ton steam hammer. Due to the impact of the hammer is not enough, only the gear stage and the hole forging out. Each gear to feed 33.3 kg. In the call for the saving of metal materials, the comrades came up with a solution, using 0.4 tons of air hammer on the hammer has been set aside from top to bottom, as shown in Figure 2 hammer and die base; the other gear into Figure 1 B , And according to the geometry of the lower half of the gear preparation of a mat model. After such an improvement, the 0.4-ton air hammer
