[0002] Aircraft engine rings are one of the key structural components in aircraft engines. They are usually subjected to high temperature, high pressure, high corrosion and high-intensity working environments. The functions of rings in the engine include supporting, connecting and fixing other components such as turbine discs and compressor discs. They play a vital role in the performance and reliability of the engine.

[0003] During the processing of aircraft engine rings, due to the properties of metal, a certain amount of deformation will occur in the aircraft engine rings, so the aircraft engine rings need to be corrected to ensure the normal size and shape of the aircraft engine rings. Existing ring correction devices mostly perform correction operations on aircraft engine rings by extruding correction rollers in opposite directions, which cannot completely eliminate the deformation state of the aircraft engine rings. For this reason, we propose a ring correction device for aircraft engine ring processing. Utility Model Content
