Abstract

The invention discloses an aero-engine conduit machining and forming device, and belongs to the field of aero-engine. The device includes a forming cone and a pipe clamping sleeve, the forming cone includes a cone body, a cone tip arranged at the front end of the cone body and a cone shank arranged at the rear end of the cone body, the cone tip includes a regulating cone core arranged at the frontend of the cone body and connected with the cone body in a movable mode and a plurality of groups of expansion cores arranged on the outer side of the regulating cone core and connected with the conebody in a rotating mode, and the expansion cores regards the regulating cone core as a center and are evenly distributed on the outer side of the regulating cone core in the circumferential direction. According to the device, the disposable forming quality of a cone face of an engine conduit is improved, and the conduit forming efficiency and the sealing performance of the conduit are improved.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to an aero-engine conduit processing and forming device. Background technique [0002] The engine ducts are all over the engine body, conveying various fluids, known as the engine "vessels". Therefore, the sealing performance of the pipe end is extremely important. At present, the sealing structure of "cone-to-cone" is generally used in the catheter assembly, and the quality of the conical surface of the pipe end plays a vital role in its sealing. The processing method of the tapered surface of the pipe end is spinning forming, that is, after the catheter is clamped, the pipe end is spin-formed with a 74° outer cone. The traditional conical head adopts an integral structure, and the conical surface of the pipe end is subjected to relatively large frictional resistance during the forming process, so that the surface finish cannot reach the Ra0.8 required by the drawing. And after proce...
