改进丝锥提高螺母生产率

Increasing Nut's Productivity by Tap Improvement

输变电线路所需的地脚螺母采用自制攻丝机配标准丝锥进行攻丝加工。按此工艺加工标准丝锥出现刀刃断裂等几种情况,增加加工成本的同时影响前方施工工期。因此丝锥改进提高螺母生产率非常重要。

The foundation nut, which is used to transmission line, is taped by a self-made tapping machine with a standard tap at present, but the blades of the standard taps are broke easier in the tapping process, so that processing costs are increased. Thereby increase nut＇s productivity by tap improvement is very important.
