Description
Technical Field
The utility model relates to the technical field of precision machining, in particular to a stator wire cutting shared tool of an aeroengine.
Background
An aero-engine stator is a part that is not rotatable relative to an aero-engine rotor, and broadly includes a casing housing and the like. This stator, as the name implies, is stationary and is fixed to the casing, and after being fixed to the casing, there is a stator behind the rotor. One very ingenious structure that the air flow of an aero-engine can go from front to back is the cooperation of the rotor and stator. After the air passes through the rotor of the first-stage compressor, the speed direction is not along the axial direction, and has an angle, so that the air is unfavorable for entering the next-stage rotor, and the flowing direction of the air needs to be changed, namely the action of the stator blades of the compressor, and in addition, the action of supercharging can be achieved by utilizing the expansion of the cascade channels. The stator blades rectify and diffuse the air flow compressed by the movable blades, and the angles of the stator blades are adjustable.
The performance of the aeroengine is largely determined by the technical level of design and manufacture of the molded surface of the stator blade, the functional life of the stator blade in the engine and the working characteristics of the stator blade, and the stator blade is one of the parts with complex shape, severe stress and maximum bearing in the engine. It operates under high pressure and high speed conditions and is usually made of special materials such as titanium alloy, high temperature alloy, etc. with very high alloying degree. To meet engine performance, operational safety, reliability, and life requirements, stator vanes must be of precise size, precise shape, and stringent surface integrity. The manufacturing technique of the blade is thus one of the complex techniques in the machine manufacturing industry.
