国内(苏联)许多工业部门正在采用一些大型结构,此类结构由表面带加强肋的大型薄壁另件所组成。这些另件是用具有严格的公差、不大的机械加工量或不需机械加工的精密模锻制造的。由于采用了模锻的另件,大部分接合件便没有必要了,从而大大减轻了制件的重 Many industrial units in the country (the Soviet Union) are using large structures consisting of large, thin-walled pieces with ribs on their surfaces. These parts are manufactured with precision forging with tight tolerances, small machining volumes or without machining. Due to the use of swaged parts, most of the joints are not necessary, thus greatly reducing the weight of parts
