管螺纹丝锥是管道联接作业中广泛应用的工具。由于管螺纹丝锥短而粗,目前大多数工厂仍采用整体高速钢材料生产,高速钢材料的利用率只有40％,实际上螺纹丝锥刃部有效的长度可小于总长度的一半。为降低丝锥的成本,减少高速钢材的消耗,合理有效地利用高速钢并能保证刀具的质量、耐用度,提高企业经济效益,在廊坊工具厂的主要产品管螺纹丝锥生产中进行摩擦焊接、焊后退火和淬回火热处理工艺的试验与研究。现已确定了合理的工艺并应用于生产。
Pipe thread tap is a widely used tool in pipe coupling operations. Due to the short and thick pipe thread taps, most factories are still using the overall production of high-speed steel materials, the utilization rate of high-speed steel material is only 40%, in fact the effective length of the thread tap edge less than half of the total length. In order to reduce the cost of tap, reduce the consumption of high-speed steel, use the high-speed steel rationally and effectively, and ensure the quality and durability of the tool, and improve the economic efficiency of the enterprise, friction welding is carried out in the production of pipe thread tap Experimental and Research on Post - annealing and Quenching - tempering Heat Treatment Process. Now that a reasonable process has been established and applied to production.
