手工针的传统生产工艺归纳起来为五道工序:一是普碳盘元冷拉成针用丝;二是把丝矫直、切条、冲眼和粗磨成针;三是半成品针渗碳、淬火及回火;四是成品针抛光;五是成品针包装入库。从以上生产针的工艺过程可知,要保证针的优质高产,关键是首先要生产出合格的针用丝,其次是搞好半成品针的化学热处理。在实际生产过程中,把普碳盘元冷拉成针用丝是比较容易的,而在制针过程中要保证针的表面有一定硬度,且
The traditional production process of hand needles can be summed up as five processes: one is to pull the carbon wire into the needles; the other is to straighten the strands, cut the strips, , Quenching and tempering; Fourth, finished needle polishing; Fifth, finished needle storage storage. From the above needle production process shows that to ensure high quality and high-quality needles, the key is to first produce qualified needle silk, followed by a good semi-finished chemical needle heat treatment. In the actual production process, it is relatively easy to pull the plain carbon disk into the needle wire, and in the process of making the needle, it is necessary to ensure that the needle surface has a certain hardness, and
