摘要
航空发动机气膜冷却孔的加工是目前航空工业中亟需解决的主要问题之一,在分析对比了各种航空发动机气膜冷却孔的加工方法优缺点的前提下,利用电解加工的优点,设计研制了一台航空发动机气膜冷却孔电解加工机床,机床主要由循环系统,进给系统,控制系统和监测系统等四部分组成,可以很好地解决航空发动机在高强度高硬度材料上具有一定倾斜角的冷却孔难加工的问题,并以某航空发动机涡轮叶片气膜冷却孔的加工为例,以镍基高温合金Inconel718为材料,对该机床结构设计的合理性和加工稳定性加以验证。
The process of Aero-engine＇s film cooling hole is one of the major problems in aviation industry. Based on the analysis that characteristics of various machining process of the film cooling holes, and depend on the advantage of Electrochemical machining, a ECM machine tool for A ero-engine＇s film cooling holes was designed and developed, there are four parts which circulation system, feeding system, control system and monitoring system, It can solve the problem that aeroengine is difficult to process the cooling holes of a certain inclination angle in high strength and high hardness material. Finally, used a certain Aero-engine turbine blade film cooling hole, the machine was verified through the experiment of nickel-based high-temperature alloys Inconel718.
