我们上海缝纫机二厂广大职工,在党的社会主义建设总路线指引下,在一九七一年,花了不到十个月的时间,自行设计和制造了一条加工缝纫机送布轴的小型自动线。 这条自动线采用了新的布局型式,生产效率很高。工件是由带叉子的输送链条直接从料仓出口带出并逐个工位的进行输送。在这条自动线上,除了钻孔、攻丝、铣削加工外,还进行车削和磨削加工。机床的动力头和刀架直接安装在一个整体的铸铁床身上,从两侧和上面对工件进行加工。切屑由床身内的吸尘管道自动排出。电气控制系统采用了无触点电子技术。工人只需将工件放入料仓,其余全部为自动循环。自动线上还设有检查中心钻折断和工件顶歪的自动停车装置。
Under the guidance of the party’s general line of socialist construction, in less than ten months in 1973, our workers and staff of our Shanghai Sewing Machine Factory designed and manufactured a small automatic line that processes the feed shaft of sewing machines. This automatic line uses a new layout type, high production efficiency. Workpieces are conveyed by the conveying chain with forks directly from the outlet of the silo and station by station. In this automatic line, in addition to drilling, tapping, milling, but also for turning and grinding. The power head and tool post of the machine are mounted directly on an integral cast iron bed and workpieces are machined from both sides and from above. Chip dust from the bed automatically discharged. Electrical control system uses non-contact electronic technology. Workers simply put the workpiece into the silo, the rest all automatic cycle. Automatic line also has a check center drill breakage and the top of the workpiece crooked automatic parking device.
