我厂于 80年代末从英国引进了一条硬质玻壳Ｈ4灯泡生产线 ,组成灯芯的三根导丝 (0 6ｍｍ)靠金属钼丝 (0 4ｍｍ)架桥固定 ,排气工序中再利用瞬时大电流将其熔断 (如图 1所示 )。灯芯组装工作靠一台装架机自动完成 ,实现了自动化生产。图 1　钼丝架桥硬质玻壳Ｈ4灯泡灯芯我 In the late 1980s, our factory imported a hard bulb H4 bulb production line from Britain. The three guide wires (0 6mm) that make up the wick are bridged by the metal molybdenum wire (0 4mm), and the instantaneous reuse Large current will blow it (Figure 1). Wick assembly work by a racking machine automatically, to achieve the automated production. Figure 1 Molybdenum wire bridge hard bulb H4 bulb wick I
