为了进一步提高齿轮毛坯的加工效率,减轻工人劳动强度,在厂党委领导下,我们以1968年自制的三台卧式液压半自动车床和一台利用报废的外拉床改装的10吨内拉床为基础,自行设计制造了一条齿坯加工自动线(图1)。该自动线1973年开始设计,同年8月建成,现已投入生产使用。 这条自动线的 In order to further improve the processing efficiency of gear rough and reduce the labor intensity of workers, under the leadership of the factory party committee, we make use of three horizontal hydraulic semi-automatic lathes made in 1968 and a 10-ton inner broaching machine converted from a scrapped outer lathe Based on their own design and manufacture of a tooth blanks automatic processing line (Figure 1). The automatic line design began in 1973, completed in August the same year, has now been put into production use. This automatic line
