不久前我们承制了大批图1那样的链条;链环是焊接的,共有7个。起初的做法是一个个环围完了,再一个个地扣在一起焊成,效率相当低。一个链条不算焊接就要400分钟左右。锻工王云峰同志学习兄弟厂的经验提出一个建议,利用废料制成一套围链环的工具,如图2所示。用这套工具围链环,可以连续地围下去,多长都
Not long ago we made a large number of chains like the one in Figure 1. The links were welded and there were seven. The initial practice was to complete the ring around one by one, and weld them together one by one. The efficiency was quite low. It takes about 400 minutes for a chain to be welded. The experience of forging comrade Wang Yunfeng’s learning of a brother factory put forward a proposal to use waste to make a set of tools for encircling the chain link, as shown in Figure 2. Use this set of tools to surround the chain, you can continue to surround it, how long are
