摘要
为提高射击精度,满足枪械对枪管内表面高质量的要求,提出一种磨料水射流光滑身管表面的方法。根据枪管具有螺旋线的结构特点,采用螺旋磨料水射流光整身管,结合磨料水射流加工方式,设计了螺旋磨料水射流的加工装置,建立磨料水射流数学模型,利用Fluent流体仿真软件,对磨料水射流加工过程进行数值分析与计算。结果表明:磨料水射流光滑身管表面加工方法是可行的,可为磨料水射流光整身管内表面加工提供参考依据。
In order to improve the shooting accuracy of the gun to meet the high quality of the inner surface of the gun barrel, a method of the abrasive water ejection in inner surface machining of gun barrel is proposed. According to the structural characteristics of the barrel with spiral line, used the spiral body abrasive water jet streamer tube, combined with abrasive water jet machining method, the machining device of spiral abrasive water jet design, establish the mathematical model of the abrasive water jet flow numerical analysis and calculation process by using Fluent fluid simulation software.The results show that the method is feasible, and it can provide a reference for abrasive water jet machining the inner surface of the tube body.
