[0026] Furthermore, the support frame 2 includes a support frame body 21, a circular arc groove 22 for supporting the forging ring rod 3 is opened on the top of the support frame body 21, a driving cavity 23 whose top is connected to the circular arc groove 22 is opened in the inner cavity of the support frame body 21, vertical sliding rods 24 are arranged on the left and right side walls of the driving cavity 23, a lifting platform 25 is slidably connected between the two groups of vertical sliding rods 24, a first electric telescopic rod 26 is installed between the bottom of the lifting platform 25 and the bottom of the driving cavity 23, and a forging ring rod driving mechanism 27 is arranged on the top of the lifting platform 25; by controlling the extension of the telescopic end of the first electric telescopic rod 26, the lifting platform 25 can be driven to rise along the vertical sliding rods 24 on both sides, thereby driving the forging ring rod driving mechanism 27 to lift, so that the top end of the forging ring rod driving mechanism 27 pushes the forging ring rod 3 upward and directly contacts it, and then the forging ring rod driving mechanism 27 is controlled to drive to drive the forging ring rod to move or rotate.

[0027] Furthermore, the front and rear sides of the arc groove 22 are provided with support balls 28 embedded in the support frame 2 and capable of rolling. When the forging ring rod driving mechanism 27 lifts and pushes the forging ring rod, the bottom of the forging ring rod contacts the top of the forging ring rod driving mechanism 27, and its side contacts the support ball 28 on one side. When the forging ring rod driving mechanism 27 drives the forging ring rod to move, the contact area between the forging ring rod and the support frame 2 can be reduced, thereby improving the flexibility of the forging ring rod.
