Forging device for high-hardness cutter

The invention belongs to the technical field of cutter forging, and particularly relates to a high-hardness cutter forging device which comprises a forging machine, a hydraulic cylinder body, a hydraulic output shaft, a mounting shell, a bearing base, a first forging head and a second forging head, the second forging head is fixedly mounted at the bottom end of the hydraulic output shaft, and the first forging head slides in the mounting shell. The second forging head extends into the first forging head, the bearing base is located below the hydraulic output shaft, the clamping assembly is arranged in the mounting shell and used for limiting sliding of the first forging head in the mounting shell, a first hole groove and a second hole groove are formed in the first forging head, and the second hole groove is located below the first hole groove. The two ends of the second forging head are arranged in a protruding mode, when the second forging head rotates to the transverse direction, the structure is used in c
