The top surface of the cutting seat 11 is symmetrically provided with the positioning sliding groove 15, and the bottom surface of the moving clamping block 14 is symmetrically connected with two positioning sliding blocks 25 positioned and sliding in the positioning sliding groove 15. When the hydraulic push-pull rod 16 drives the moving clamping block 14 to move, the positioning sliding block 25 moves in the positioning sliding groove 15 to position the movement of the moving clamping block 14. In addition, the fixed clamping block 13 is installed on the cutting seat 11 by bolts, and the moving clamping block 14 is connected with the hydraulic push-pull rod 16 by bolts, which are detachable connection modes. When different specifications and sizes of steel bars need to be cut, the fixed clamping block 13 and the moving clamping block 14 can be disassembled to replace the first positioning clamping arc-shaped notch 19 and the second positioning clamping arc-shaped notch 24 of appropriate size, so that the steel bars of different specifications and sizes are clamped by the first positioning clamping arc-shaped notch 19 and the second positioning clamping arc-shaped notch 24.

[0036] In this embodiment, the support column 31 can rotate freely in the hollow column pipe 27 and is fixed in position by tightening the first locking knob 28.

The threaded end of the first locking knob 28 is screwed into the hollow column pipe 27 and abuts the outer wall of the support column 31, locking the position of the support column 31 and the U-shaped side support frame 8.

[0038] In this embodiment, the second locking knob 29 acts on the steel bar through threads, increasing the friction force and ensuring that the steel bar does not shift during cutting. It provides an additional fixed point to further enhance the stability of the steel bar during cutting and reduce cutting errors caused by vibration. The top surface of the U-shaped side support frame 8 is longitudinally threaded with the second locking knob 29. The screw end of the second locking knob 29 penetrates into the U-shaped side support frame 8 and presses against the outer wall of the steel bar. When the steel bar is clamped in the U-shaped side support frame 8 by the support frame, the position of the steel bar can be locked by tightening the second locking knob 29 and pressing the screw end of the second locking knob 29 against the steel bar.

[0041] In this embodiment, a distribution box (not shown in the figure) is provided at the lower part of the steel cutting workbench 1, and a junction box (not shown in the figure) is provided at the bottom of the cutting machine base 11. The junction box has a PLC for controlling the opening and closing of the hydraulic push-pull rod 16 and the lower pressure cylinder 22. The model of the PLC can be selected according to actual needs.

[0042] Working principle:

[0043] The steel cutting device for water conservancy and hydropower construction moves the steel cutting workbench 1 to the appropriate position and fixes the workbench with the locking support feet 5 at the bottom to ensure its stability. The side support assembly 10 is adjusted as needed, the direction of the U-shaped side support frame 8 is manually adjusted by loosening the first locking knob 28, so that it can stably support the two ends of the steel bar to be cut. After completion, the first locking knob 28 is tightened to lock the position.

[0044] The steel to be cut is placed on the steel cutting workbench 1, and the position of the steel to be cut needs to be clamped between the fixed clamping block 13 and the movable clamping block 14, and the other end of the steel is clamped into the U-shaped side support frame 8 of one side support assembly 10, and the other end is clamped into the U-shaped side support frame 8 of the other side support assembly 10, and the position of the steel is further fixed by tightening the second locking knob 29, and the movable clamping block 14 is driven by the hydraulic push-pull rod 16 to move towards the fixed clamping block 13, so that the steel is gradually clamped, and the first positioning clamping arc-shaped notch 19 of the fixed clamping block 13 and the second positioning clamping arc-shaped notch 24 of the movable clamping block 14 will fit and clamp the steel, especially when the steel has an outer wall protruding thread, the thread fitting groove 20 will also play an auxiliary clamping role, increasing the stability.

[0045] When the movable clamping block 14 gradually clamps the steel towards the fixed clamping block 13, in order to ensure that the bottom of the steel is parallel to the top surface of the cutting seat 11 and prevent the appearance of a seesaw, the lower pressing cylinder 22 is started, and the lower pressing piston rod 23 is quickly pressed downwards to press the steel, ensuring that it is stably placed on the cutting seat 11, and then the lower pressing piston rod 23 is quickly retracted, and the movable clamping block 14 is driven by the hydraulic push-pull rod 16 to move towards the fixed clamping block 13, so that the steel is further clamped.

[0046] The operator holds the handle frame 12 and drives the cutting cutter 7 to descend to cut the steel. During the cutting process, the transparent protective plate 6 can protect the safety of the operator, and after the cutting is completed, the cutting cutter 7 is lifted by the handle frame 12 to release the clamping of the steel, and the second locking knob 29 on the side support assembly 10 is released, and the cut steel section is taken out.

[0047] If it is necessary to continue to cut steels of different specifications or lengths, the above steps can be repeated, and if necessary, the fixed clamping block 13 and the movable clamping block 14 of the appropriate size are replaced, and are disassembled and reassembled to adapt to new requirements.
