[0054] Furthermore, after the forging moves to the position of the hydraulic press 2, the electric push rod 45 is started, the electric push rod 45 drives the compression plate 47, and the compression plate 47 drives the buffer spring 21, so that the buffer spring 21 is restored from the compressed state to the original state, and the hydraulic press 2 is started. The hydraulic press 2 forges the forging. After the hydraulic press 2 applies the forging pressure, the forging is subjected to a downward impact load. The forging drives the clamping block 23, the movable plate 20, the mounting block 22, and the buffer seat 14 to move downward.
