以前我厂生产的JA1—1型家用缝纫机零件梭床圈(见图1)是用15号钢,直径为φ4.75毫米的线材卷料,分别经过校直机校直、切断(每根约3米长)——冲床切断(根据工件的展开长度)——滚磨机用木屑擦光、整理装箱——冲床卷圆而成。需四道工序,四台设备,五个工人操作,工序间还要来回搬运,五个人的日产量为6000只,它不但占用场地大,生产效率低,而且很不安全。
Before I plant the JA1-1 home sewing machine parts shuttle bed ring (see Figure 1) is 15 steel, diameter of 4.75 mm wire rod material, respectively, after alignment straightening machine straight, cut off (each about 3 meters long) - Punch off (according to the unwinding length of the workpiece) - Roller mill polished with sawdust, packing - Punch rolled. Four processes, four devices and five workers are required to operate. The process also has to be carried back and forth. The daily output of five people is 6000, which not only occupies a large space but also has low production efficiency and is not safe.
