制造叶片组件的方法

Method of manufacturing a blading component

Abstract

本发明涉及一种制造用于涡轮机低压导流叶片的金属叶片区(1)的方法,所述叶片区的至少一个叶片(14)包含一个内部腔体(13)和形成在壁上的至少一个孔(19),所述内部腔体用于容纳气体检测探头或与气体检测探头相通,所述至少一个孔(19)构成了气体从涡轮机低压区向所述腔体(13)和所述探头的通道,所述方法通过将对应于所述腔体(13)的型芯安装到铸模并在所述铸模的腔中铸造熔融金属来制造所述金属叶片区。这种方法的特征在于,对于用于与所述腔连通的每个孔(19)而言,所述型芯(20)包括突起物(22),该突起物(22)穿透模型的内部表面,并构成了将型芯(20)保持在铸模中的适当位置的唯一因素。
