挤压丝锥由于它的优点,越来越受到欢迎,特别在仪器、电器、柴油机、航空、航天等工业中得到广泛使用。工业发达国家挤压丝锥的使用率一般占整个丝锥的10％左右,而我国只占丝锥总数的1～2％。我厂从1984年投入批量生产挤压丝锥以来,通过不断改进,按ISO精度标准设计制造了M8～M22系列的磨制挤压丝锥,会同我厂独特工艺手段制造的M2～M6非磨制挤压丝锥,规格已基本复盖了常用的内螺纹加工系列。近年来,挤压丝锥又出现了一些新结构的设计,在使用方面也积累了许多经验,现在除可加工紫铜、纯铁、铝及其合金外,还能加工多种合金钢,如42CrMo、35CrMo、1Cr18Ni9Ti、20CrMnMo的螺孔。现就挤压丝锥在设计、制造及使用中的一些问题介绍如下:
Due to its advantages, extruded tap has become more and more popular, especially in the fields of instruments, electrical appliances, diesel engines, aviation and aerospace. The utilization rate of extruded tap in industrialized countries generally accounts for about 10% of the total tap, while our country only accounts for 1 ~ 2% of the total number of tap. Since 1984, our factory put into mass production squeeze tap, through continuous improvement, according to ISO precision standard design and manufacture of M8 ~ M22 series of grinding squeeze tap, in line with our unique manufacturing process M2 ~ M6 non-grinding squeeze Taps, specifications have been basically covered by the commonly used thread processing series. In recent years, extrusion tap has emerged a number of new structure design, also has accumulated a lot of experience in the use, now in addition to processing copper, pure iron, aluminum and its alloys, but also processing a variety of alloy steel, such as 42CrMo, 35CrMo, 1Cr18Ni9Ti, 20CrMnMo screw hole. Now extruded tap in the design, manufacture and use of some of the problems described below:
