The invention belongs to the field of aluminum alloys and discloses a manufacturing method of an aluminum alloy forging ring based on a shearing die for punching, and relates to the manufacturing method of the aluminum alloy forging ring. The manufacturing method of the aluminum alloy forging ring based on the shearing die for punching aims to effectively solve the problem of long production period of aluminum alloy in the forging ring production process and reduce labor cost and energy consumption. The manufacturing method comprises the steps that first, material selection of a novel shearingdie is carried out; second, design of the novel shearing die is carried out; third, an aluminum alloy ingot is casted; fourth, free forging of blank is carried out; fifth, solid die punching of a forge piece is carried out; sixth, novel shearing die punching of the forge piece is carried out; seventh, forging ring of the forge piece is carried out; and eighth, machining of the forge piece is carried out. The manufacturing method of the aluminum alloy forging ring based on the shearing die for punching has the advantages that the manufacturing method effectively solves the problem of long production period and reduces the labor cost and the energy consumption, and the manufacturing method is of great political significance and great social benefits to the strengthening of national defensestrength of China.
