摘要
介绍金刚线市场状况,针对水箱拉丝机采用23模拉拔金刚线母线出现断丝率高、圈径不稳、中心开裂、成品率低等问题,进行套模拉拔、二次拉拔、双机联动等试验,发现使用套模拉拔0.07 mm金刚线母线,产品成材率为38%,各项技术指标可满足客户要求。
To introduce the market status of the diamond wire. In view of the problems when drawing the master wire for diamond wire with wet drawing machine with 23 dies,the experiments such as sleeve drawing,secondary drawing,double machine linkage,etc. are carried out in order to solve the problems of high wire breaking rate,unstable ring diameter,and low finished product rate and so on. It is found that the finished production rate of the diameter 0. 07 mm master wire with sleeve drawing is 38%,the technical indexes can meet the requirements of the customers.
