我厂生产的 CD 型电动葫芦,七种产品上共有二十八种齿轮,是在300～1000吨摩擦压力机上模锻成形。以前均用3Cr2W8或5CrNiMo 为镶块,每年就需十多吨模具钢。现经车间工人同志们试验,改用45钢代替,几个月来对四种齿轮进行模锻试验,基本上达到用模具钢做镶块时模锻的产品数量。所采取的措施有:1.镶块放大到φ360毫米,厚度为120毫米;

I plant production of CD-type electric hoist, seven kinds of products on a total of 28 kinds of gear, is in the 300 ~ 1000 tons of friction press die forging. Previously used 3Cr2W8 or 5CrNiMo as inserts, each year requires more than 10 tons of mold steel. Now the workshop workers comrades to test, instead of using 45 steel instead of a few months for the four gear forging test, basically to do with the mold steel when the number of products forged with inserts. The measures taken are: 1. Inset enlarged to φ360 mm, a thickness of 120 mm;
