[0028] In this embodiment, first, the rack 37 is meshed and moved on the third gear 38 driven by the output end of the second servo motor 36, so that the active square clamp 311 is moved downwardly close to the driven square clamp 312, and the plate material is clamped.

This solves the problem that the original clamping device of the existing arc bending machine cannot effectively clamp the plate material and the tube material at the same time during the material processing.

[0029] Embodiment 2:

When the top of the threaded rod 23 abuts against the baffle 212, the fixed clamping plate 25 is pushed to move outward in the adjustment box 22. After the active roller 27 fixed in the fixed clamping plate 25 and the driven roller 47 are adjusted to a suitable distance, the third servo motor 42 in the inner box 41 is turned on to drive the first gear 44 on the rotating rod 43 to rotate and drive the second gear 45 to rotate, so that the driven roller 47 set on the top of the driven rod 46 fixed in the rotating rod 43 and the second gear 45 rotates, and the rack 37 moves by meshing on the third gear 38 driven by the second servo motor 36, so that the active square clamp 311 moves downward , the processing material is clamped and fixed by the driven square clamp 312.
