摘要
新结构涡轮盘最大的特点是具有双翼安装边结构,且与轮盘辐板形成大深度半封闭型腔,加工难度大,同时该类涡轮盘直径大,薄壁刚性差,加工变形严重。重点围绕薄壁双翼安装边新结构涡轮盘加工中的技术关键和瓶颈,通过大量试验研究,设计出一套全新的薄壁双翼安装边结构涡轮盘机械加工工艺,制定了控制加工变形的措施和方案,通过优化工件加工工艺路线和数控加工工艺方案,优选刀具材料、刀具结构,分析摸索薄壁涡轮盘加工变形规律,保证了工件的加工质量。
Turbine disks of a certain tape of aeroengine with the new structure have some features as follow: wings installation edge structure,semi- closed cavity,large diameter,poor stiffness,serious machining deformation. This paper mainly focuses on the bottleneck technique of the new structural turbine disk parts processing. Through a large number of experiments,we make detailed description about designing a new deformation- controlling strategy,optimizing turbine disk parts processing and NC machining process,choosing the material and structure of tools,analyzing the regulation of machining deformation.
