[0012] The beneficial effects of the utility model are:

[0013] 1. This construction steel bar cutting equipment inserts the steel bar between the driving wheel and the driven wheel, and then the elastic force of the compression spring will always give the driven wheel a downward force, thereby pressing the steel bar. It can adapt to steel bars of different thicknesses and improve practicality. Then, the driving wheel will be driven to rotate by starting the servo motor.

[0022] See also Figure 1 A fixing plate 7 is fixedly installed on the top of the bracket 1, a hydraulic rod 8 is fixedly installed on the end of the fixing plate 7, and the bracket 1 also includes a fixed-length cutting component 9 and a steel bar cutting component 10, and the steel bar cutting component 10 is located directly below the hydraulic rod 8.

[0023] See also Figure 2-3 The fixed-length cutting component 9 includes a stand 11 and a fixed rod 20. A slide groove 12 is provided at the top of the stand 11. A moving block 13 is slidably connected inside the slide groove 12. The front of the moving block 13 is rotatably connected to a swing plate 14. A plug rod 15 is inserted at the top of the swing plate 14. A positioning screw 16 is threadedly connected to the back of the moving block 13. A frame 17 is fixedly installed on the top side of the stand 11. A push rod 18 is provided at the top of the slide groove 12 and located in the frame 17. A plug hole 19 is provided inside the push rod 18. The plug rod 15 penetrates and is inserted into the plug hole 19. The end diameter of the positioning screw 16 is larger than the inner diameter of the slide groove 12. By twisting the positioning screw 16, the moving block 13 will be limited. As the steel bar is transmitted, it will abut against the bottom of the swing plate 14, and then the swing plate 14 will be pushed to rotate and drive the push rod 18 to move to the side of the fixed rod 20.

[0024] See also Figure 2-3 A sleeve 21 is sleeved on the top of the fixed rod 20, a compression torsion spring 22 is fixedly installed between the bottom side of the sleeve 21 and the fixed rod 20, an L-shaped plate 23 is fixedly installed on the top outer side of the sleeve 21, and the L-shaped plate 23 is located on the moving path of the push rod 18. The push rod 18 will push the L-shaped plate 23 to deflect to the bottom of the hydraulic rod 8, and then it will be cushioned between the hydraulic rod 8 and the steel bar cutting component 10, so as to facilitate the cutting of the steel bars.

[0025] See also Figure 4The steel bar cutting component 10 includes a fixing frame 24, a lower blade 25 is fixedly installed in the middle of the fixing frame 24, an upper blade 26 is slidably connected in the top of the fixing frame 24, support plates 27 are fixedly installed on both sides of the upper blade 26, and a return spring 28 is fixedly installed on the bottom side of the support plate 27. The upper blade 26 is located directly below the hydraulic rod 8, and a gap is left between the lower blade 25 and the upper blade 26 for the steel bar to pass through. The lower blade 25 and the upper blade 26 are staggered and are deflected and padded on the top side of the upper blade 26 through the L-shaped plate 23. Then, by starting the hydraulic rod 8, the upper blade 26 will be squeezed and moved downward, thereby cutting the steel bar.

[0026] When using, refer to Figure 1-4 , first start the servo motor to drive the driving wheel 2 to rotate, and then insert one end of the steel bar between the driving wheel 2 and the slider 3. At this time, under the action of the compression spring 6, the driven wheel 4 will be driven to press the steel bar, and then the driving wheel 2 will drive the steel bar forward as it rotates. The steel bar will then pass between the lower blade 25 and the upper blade 26 until it contacts the swing plate 14, which will push the swing plate 14 to deflect, and then drive the push rod 18 to move to the side close to the L-shaped plate 23, so it will push the L-shaped plate 23 to deflect to the top of the upper blade 26. At this time, the hydraulic rod 8 is started to press downward on the L-shaped plate 23, and then the upper blade 26 will be driven to move downward, so the steel bar in the middle will be cut off, and then the upper blade 26 will be driven to reset through the reset spring 28, and the L-shaped plate 23 will be driven to reset through the compression torsion spring 22, so that the steel bar can be automatically cut to a fixed length;

[0027] When the length of the cut steel bar needs to be adjusted, it is only necessary to pull the insertion rod 15 out of the insertion hole 19, and then turn the positioning screw 16 to no longer restrict the moving block 13. At this time, the moving block 13 can be pushed to slide to the specified length position, and then the positioning screw 16 is turned in the opposite direction to position the moving block 13, and then the insertion rod 15 is inserted into the insertion hole 19.

[0028] To sum up, the construction steel bar cutting equipment inserts the steel bar between the driving wheel 2 and the driven wheel 4, and the compression spring 6's own elastic force will always give the driven wheel 4 a downward force, thereby pressing the steel bar, and can adapt to steel bars of different thicknesses to improve practicality. Then, the driving wheel 2 will be driven to rotate by starting the servo motor. Since the steel bar is squeezed and clamped between the driving wheel 2 and the driven wheel 4, it will drive the steel bar to be transmitted forward, thereby playing a role of automatic feeding and reducing the labor intensity of workers.

[0029] The steel bars are transported forward and contact the swing plate 14, which in turn pushes the swing plate 14 to rotate, thereby driving the push rod 18 to push the L-shaped plate 23 to rotate, so that the L-shaped plate 23 rotates to between the hydraulic rod 8 and the upper blade 26, and then starting the hydraulic rod 8 will drive the return spring 28 to move downward, so the steel bars will be cut. At the same time, by driving the moving block 13 to change the position of the swing plate 14, the cutting length of the steel bars will be adjusted, so that the steel bars can be quantitatively cut according to needs.
