一、改变零件結構图1甲是万向节义(傳动軸),用2吨錘模鍛。后来改成如图1乙那样的形狀,用1600吨机械鍛压机模鍛:这样,每个零件可以节約2.38公斤鋼材(35鋼),材料利用率提高8.7％。图2甲是变速齿輪的原来結構,把它的尺寸改成图2乙那样,每个可以节約1.0公斤鋼材(18ХΓТ),材料利用率提高0.08％。图3甲的主动螺旋傘齿輪原来是在3吨錘上模鍛成的,后来改用6吋平鍛机模
First, to change the part structure Figure 1 is a universal joint justice (transmission shaft), with 2 tons of hammer forging. It was later changed to the shape shown in Figure 1 B and forged with a 1600-ton machine forging press: This saves 2.38 kg of steel (35 steels) per part and an 8.7% increase in material utilization. Figure 2 A is the original structure of the variable speed gear, its size changed to Figure 2 B, each can save 1.0 kg of steel (18ХΓТ), material utilization increased by 0.08%. Figure 3 A active helical bevel gear was originally on the 3-ton hammer forged into, and later switched to 6-inch flat forging die
