Radial forging machine is a machine that forges shaft parts along the diameter direction, it is a special equipment dedicated to the radial forging process, and belongs to one of the advanced forging equipment with less and no cutting processing. Since the emergence of radial forging machine in the 50s of the 20th century, it has been recognized and vigorously developed by production enterprises due to its advantages of high forging efficiency, high degree of automation, saving forging materials, good forging quality, simple tooling and strong applicability. The striking force of the radial forging machine that can be produced in China is 1000~2000kN, the diameter of the forgeable bar is 80~160mm, and the maximum length of the malleable blank is 2500mm.
