[0002] Rebar refers to steel used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. It includes plain round bars, ribbed bars, and twisted bars. Rebar for reinforced concrete refers to straight or coiled steel used for reinforcing reinforced concrete. Its shape is divided into two types: plain round bars and deformed bars. It is delivered in two states: straight bars and coils. Plain round bars are actually small round bars and coils of ordinary low carbon steel. Deformed bars are ribbed bars, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The transverse ribs are spiral, herringbone, and crescent-shaped.

In this embodiment, the limiting frame 10 facilitates the sliding of the slider 9, and the drive motor 8 drives the saw blade 6 to rotate.

[0037] Reference Figure 4 , Figure 5 and Figure 6 A collecting device 13 is provided on one side of the fixing plate 12. The collecting device 13 includes a mounting cavity 14. A constant speed motor 15 is provided inside the mounting cavity 14. A threaded rod 16 is provided on the output shaft of the constant speed motor 15. A threaded cylinder 17 is provided on the outside of the threaded rod 16. A collecting plate 18 is provided on the top of the threaded cylinder 17. A sliding groove 19 is provided inside the collecting plate 18. A sliding plate 20 is provided inside the sliding groove 19. A mounting plate 21 is provided on the top of the sliding plate 20. In this embodiment, the mounting cavity 14 serves to fix the constant speed motor 15. The constant speed motor 15 serves to drive the threaded rod 16 to rotate. The threaded rod 16 serves to drive the screw cylinder 17 to move.

[0038] Reference Figure 4 and Figure 5 The collecting plate 18 is fixedly connected to one side of the fixed plate 12, the mounting cavity 14 is opened inside the fixed plate 12, the constant speed motor 15 is fixedly connected to the inside of the mounting cavity 14, and the threaded cylinder 17 is fixedly connected to the slide plate 20. In this embodiment, the collecting plate 18 plays the role of collecting steel bars, and the slide plate 20 plays the role of collecting steel bars.

[0039] Reference Figure 4 , Figure 5 and Figure 6 The slide plate 20 is slidably connected to the inside of the slide groove 19, the threaded rod 16 is adapted to the threaded cylinder 17, and the mounting plate 21 is fixedly connected to the top of the slide plate 20. In this embodiment, the slide groove 19 facilitates the sliding of the slide plate 20, and the threaded cylinder 17 drives the slide plate to move.

[0040] Reference Figure 7 A monitor 22 is provided at the bottom of the mounting plate 21, and a control module 23 is provided at the top of the mounting plate 21. In this embodiment, the monitor 22 is used to monitor the length of the reinforcing bar, and the control module 23 is used to send and receive signals.

[0041] The implementation principle of this embodiment is as follows:

[0042] In actual use, one end of the rebar coil is first placed into the rebar straightening machine 1. After passing through the rebar straightening machine 1, the bent rebar is straightened and then inserted into the connecting cylinder 5. After passing through the connecting cylinder 5, the straightened rebar is pushed to the top of the collecting plate 18. When the monitor 22 detects that the rebar has moved to the designated position, it sends a signal to the control module 23. The rebar straightening machine 1 stops working and controls the drive motor 8 to start working. The drive motor 8 drives the saw blade 6 to rotate rapidly inside the lifting frame 7. At the same time, the output shaft of the electric push rod 11 retracts synchronously, driving... The lifting frame 7 moves downward. As the lifting frame 7 moves downward, it drives the rotating saw blade 6 to contact the steel bar. When the output shaft of the electric push rod 11 is fully retracted, the steel bar is cut off. After the steel bar is cut off, the output shaft of the electric push rod 11 will quickly extend upward and push the lifting frame 7 upward until the saw blade 6 is reset. The control module 23 will receive the signal that the electric push rod 11 has completed one-sided extension and retraction and control the steel bar straightening machine 1 to start working. Through the subsequently straightened steel bar, the cut steel bar is completely pushed to the top of the collecting plate 18 and the above steps are repeated to quickly cut the steel bar.

[0043] When it is necessary to cut the steel bars to different lengths, the constant speed motor 15 starts working and drives the threaded rod 16 to rotate. Through the cooperation of the threaded rod 16 and the threaded cylinder 17, the slide plate 20 can be driven to slide inside the slide groove 19, thereby changing the distance between the mounting plate 21 and the collecting plate 18. During the sliding of the slide plate 20, the mounting plate 21 will be moved together. The monitor 22 and the control module 23 are fixedly connected to both sides of the mounting plate 21. The length of the steel bar to be cut can be determined according to the extension length of the slide plate 20. The collecting plate 18 and one side of the slide plate 20 are set as slopes, so that the cut steel bars will roll to one side. Push the cart to the bottom of the collecting plate 18, and the steel bars will roll to the top of the plate, saving the workers the step of collection and thus saving physical strength.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] The base 3, support plate 4, and connecting cylinder 5 work together to support the reinforcing bars. The electric push rod 11 and lifting frame 7 work together to lift the saw blade 6. The addition of a drive motor 8 drives the saw blade 6 to rotate. By using the above structure, the cutting work can be completed directly after the reinforcing bars are straightened, thereby improving work efficiency. The collection plate 18 and sliding plate 20 work together to collect the reinforcing bars. The fixed speed motor 15, threaded rod 16, and threaded cylinder 17 work together to move the sliding plate 20. The groove 19 facilitates the storage of the sliding plate 20. By using the above structure, the cut reinforcing bars can be collected, thereby reducing the labor intensity of the workers.
