[0019] like Figure 1-4As shown, the utility model proposes a steel bar cutting device for water conservancy and hydropower construction, including an outer box 1 and a cutting machine 2. A pair of feed rollers 11 and a pair of traction rollers 12 are rotatably connected in the outer box 1. A driving box 14 is fixed on the outer side of the outer box 1 and at a position corresponding to the feed rollers 11 and the traction rollers 12. A driving device that drives the feed rollers 11 and the traction rollers 12 to rotate is fixed in the driving box 14. A group of adapting grooves 13 are opened on the feed rollers 11 and the traction rollers 12. The opening size of the adapting grooves 13 decreases in sequence. The cutting machine 2 is installed above the outer box 1 and is located between the feed rollers 11 and the traction rollers. A driving assembly is arranged above the outer box 1 between the guide rollers 12, a guide sleeve 4 is fixed at the front end of the outer box 1 at a position corresponding to the adaptation groove 13, a through hole 41 with the same size as the adaptation groove 13 is provided in the center of the guide sleeve 4, a positioning plate 6 is installed inside the outer box 1 and located at the traction roller 12, a telescopic cylinder 61 is fixed between the rear side of the positioning plate 6 and the outer box 1, a support block 5 is fixed inside the outer box 1 and located below the cutting machine 2, the upper end of the support block 5 is a U-shaped structure, and stabilizing grooves 51 corresponding to the adaptation groove 13 are provided on both sides of the upper end of the support block 5, and a discharge groove 15 is provided on the rear side arm of the outer box 1.

[0020] The driving assembly includes a track plate 3 and a servo motor 33. The track plate 3 is fixed to the inner wall at the top of the outer box 1. A track block 31 is slidably connected inside the track plate 3. The track block 31 is fixed to the top of the cutting machine 2. The servo motor 33 is fixed to the outside of the outer box 1 and aligned with the track block 31. A screw rod 32 is rotatably connected inside the track block 31. The screw rod 32 passes through the track block 31 and is threadedly connected to the track block 31. The end of the screw rod 32 is fixed to the output end of the servo motor 33.

[0021] An indicator rod 63 is fixed at the middle position of the upper end of the positioning plate 6, an upper end slot 62 is opened at the upper end of the outer box 1 and corresponding to the indicator rod 63, a ruler 64 is fixed at the upper end of the outer box 1 and aligned with the opening of the upper end slot 62, and the upper end of the indicator rod 63 extends out of the upper end slot 62.
