The first clamping arm 2 and the second clamping arm 3 both include a fixed part 21 and a clamping end 22. Clamping blocks 11 are arranged at the clamping ends 22 of the first clamping arm 2 and the second clamping arm 3. The clamping blocks 11 are floatingly arranged, and the opposite side surfaces of the two clamping blocks 11 are both arranged as arc surfaces. When clamping the steel ball blank 5 through the clamping blocks 11, the arc surface setting can enable the clamping blocks 11 to better clamp the steel ball blank 5. The rotating part 4 includes a rotating shaft 41 arranged on the bearing plate 1 and a gear 42 rotatably connected to the rotating shaft 41. The gears 42 in the two rotating parts 4 are meshed with each other, and the meshing of the gears 42 ensures the synchronous movement of the first clamping arm 2 and the second clamping arm 3.

[0025] Refer to Figure 1 ,Figure 2 and Figure 3 , it further includes a driving component 6. The driving component 6 uses a driving cylinder. Cylinder drive is adopted, with a high beat and a simple control structure. The cylinder stroke can be flexibly adjusted according to different bar stock specifications to change the clamping range.

[0026] Reference Figure 1 、 Figure 2 and Figure 3 , the telescopic end of the driving cylinder 6 is connected to the fixed parts of the first clamping arm 2 and the second clamping arm 3 through a connecting piece 7. The first clamping arm 2 and the second clamping arm 3 are driven by the driving component 6 to perform relative movement, so that the clamping ends in the first clamping arm 2 and the second clamping arm 3 cooperate with each other to clamp the steel ball blank 5 to be forged. Wherein, the connecting piece 7 includes a first connecting rod 71 connected to the fixed part 21 of the first clamping arm 2, a second connecting rod 72 connected to the fixed part of the second clamping arm 3, and a third connecting rod 73 connected to the telescopic end of the driving cylinder 6.

A shock absorber 10 is arranged between the lower end surface of the other end of the bearing plate 1 and the connection position of the moving part 9. The shock absorber 10 uses a shock absorption spring. When forging the steel ball blank 5, a certain vibration force will be applied to this straightening device. The vibration absorption springs 8 and the shock absorption springs 10 play a role in energy absorption and shock reduction, protecting the straightening device, reducing the damage of the vibration force to this straightening device.
