在锻工车间,常常要用圆锯片的锯床来切割大型胚料。工人在做这个工作时,要花很多的时间和费很大的力气来安装和拆卸胚料。因而就使劳动生产率降低,并使工人的劳动强度增加。苏联工人马杰拉莫夫同志提出建议,采用机械化装置——斜面滚料机,因而使劳动强度降低,并提高了劳动生产率。斜面滚料机的结构很简单,如图1所示,钳工与焊工在8小时内就 In the forging shop, it is often necessary to use a circular saw blade to cut large blanks. When workers do this work, they have to spend a great deal of time and effort on installing and removing blanks. Thus reducing labor productivity and increasing the labor intensity of workers. Comrade Majramov, a Soviet worker, put forward a proposal to use a mechanized device, a bevel roller, to reduce labor intensity and increase labor productivity. Beveling roller structure is very simple, as shown in Figure 1, fitter and welder in 8 hours
