Abstract

The invention discloses a stator blade finish forging automatic machining method. The method adopts a self-adaption machining technology, and blade deviation, torsion, profile surface tolerance and machining consistency are ensured. The method is simple in machining procedure, computer control and management are adopted, controlled devices completely automatically finish the sequential operation,the degree of automatic operation is improved, multiple devices, multiple passes of procedures, repeated clamping and repeated standard conversion for original stator blade machining are reduced intotwo passes of procedures of machining, two times of clamping and one time of standard conversion on one kind of equipment, labor is saved, the production period of parts is shortened, and the production efficiency is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of aeroengine blade processing, and in particular relates to an automatic processing method for precision forging stator blades. 【Background technique】 [0002] At this stage, the processing technology of the stator blade mainly adopts die forging blanks, and the main process of the process is: (1) the milling basin, the long side of the back side edge plate and the process convex table; (2) the milling basin, the length of the back side edge plate Side and process boss surface; (3) milling row, end of air intake side edge plate; (4) milling edge plate bottom surface, process boss end face; (5) milling, exhaust side lower edge plate end face; ( 6) CNC milling basin, back side blade body, lower edge plate surface and upper and lower edge plate transfer R; (7) milling basin, back side edge plate long side; (8) milling, exhaust side edge Plate end; (9) Grinding inlet and exhaust side lower edge plate end; (1...
