The invention provides a manufacturing method of a guide pipe, and belongs to the technical field of machining. The manufacturing method comprises the steps that a plurality of guide vane prefabricated parts are machined; coaxially welding a middle flange outside the middle part of the annular inner plate to form an inner plate assembly; a suspension connecting flange, the inner plate assembly and a guide pipe shaft are coaxially positioned and assembled together, so that the suspension connecting flange is located at the first end of the inner plate, and the guide pipe shaft is sleeved with the suspension connecting flange and the inner plate assembly; for each guide vane prefabricated part, the guide vane prefabricated part is positioned and installed between the inner plate assembly and the guide pipe shaft through the clamping section, and the two non-clamping sections are attached to the inner wall of the inner plate and the outer wall of the guide pipe shaft correspondingly; the guide vane prefabricated part is welded to the inner plate and the guide pipe shaft respectively, and a welding part is obtained; and all the clamping sections in the welding piece are machined, and the guide pipe is obtained. The processing precision can be improved.

    本公开提供了一种导管的制作方法,属于机械加工技术领域。所述制作方法包括:加工多个导叶预制件;将中间法兰同轴焊接在环形的内板的中部外,形成内板组件;将悬架连接法兰、所述内板组件以及导管轴同轴定位装配在一起,使得所述悬架连接法兰位于所述内板的第一端处,且与所述内板组件均套在所述导管轴外;对于每个所述导叶预制件,通过所述夹持段将所述导叶预制件定位安装在所述内板组件与所述导管轴之间,且所述两个非夹持段分别与所述内板的内壁以及所述导管轴的外壁贴合;将所述导叶预制件分别与所述内板和所述导管轴焊接在一起,得到焊接件;对所述焊接件中的各个夹持段进行机加工,得到所述导管。本公开可以提高加工精度。
