石油套管用特殊螺纹接头数控加工方法研究

摘要

The premium connection has high connection strength and good sealing performance and is used in oil casing more and more. A new premium connection was developed and NC process method for the premium connection was researched by analyzing the thread structure and current process conditions. In the method, circulate instruction of thread processing were quoted twice. The pro-gram was illustrated based on FANUC NC system.%特殊螺纹接头具有较高的连接强度和良好的密封性能,在石油套管中的使用越来越多.提出一种新型特殊螺纹接头,通过分析其螺纹结构及现有加工条件,提出采用数控车床通过两次螺纹车削循环指令加工该特殊螺纹的方法,并基于FANUC数控系统进行了编程举例.
