A forming method of a check ring of a combustion chamber of an aero-engine comprises the following steps of forming a cavity through punching for constituting the check ring, punching an opening part at 60 degrees, 30 degrees and 0 degree after the cavity is positioned by a fixture to achieve forming of a flange of the opening part, and taking the formed check ring out of the fixture finally. The invention provides the forming method and the fixture of the check ring of the combustion chamber of the aero-engine to solve the problem that a flange of the opening part of the check ring of the combustion chamber of the aero-engine is difficult to machine and form, and the flange of the opening part of check ring of the combustion chamber of the aero-engine can be formed by punching at 60 degrees, 30 degrees and 0 degree via ordinary punch forming equipment. The method is simple to implement, low in cost and suitable for small batch or single-piece production and does not require special equipment. The invention further provides the fixture for the method.
