The embodiment of the invention discloses a process for forging a regular polygonal forged ring, which comprises the following steps of: (1) placing a round ring blank on a convex angle forming die; (2) rotating a round mandrel on a mandrel supporter such that the round mandrel drives the convex angle forming die and the round ring blank to rotate, and stopping rotation when the convex angle of the convex angle forming die just points to the concave angle of a concave angle forming die and the round ring blank rotates to the preset position; (3) controlling a movable cross beam of a hydraulic press such that the concave angle forming die downwards presses the round ring blank and the round ring blank forms the preset angle under the action of the concave angle forming die and the convex angle forming die; (4) repeating the steps (2) and (3) such that the round ring blank is forged into a ring blank with multiple angles; and (5) respectively straightening the multiple edges of the ring blank through pressing t
