摘要
本文提出的锥管螺纹挤压丝锥，适用于１６Ｖ２４０ＺＪＢ（Ｃ）型柴油机机体联结管Ｒｃｌ／４锥管螺纹孔的加工。针对锥管螺纹联结性质，设计了两种工艺底孔。实践证明，用锥管螺纹挤压丝锥，采用圆锥底孔，加工柴油机机体联结管Ｒｃｌ／４锥管螺纹孔，攻丝效率高，工件连接强度高，丝锥寿命长。
In this paper, the extrusion tap for tap thread tUbe is introduced.This tapis suitable for Rcl/4 tap thread of 16V240 2JB (C) dieSel engine connection tube.Practiceproved that this tap has a high efficiency and long life in thread machining.
