Description

Technical Field

[0001] This utility model relates to the field of rebar cutting technology, and in particular to a rebar cutting device. Background Technology

[0002] Steel bars are widely used in the construction industry as a building material. During the use of steel bars, due to their different uses, they often need to be cut to the required length. Therefore, when a large amount of work is involved, steel bar cutting is an essential step.

[0003] Burrs often appear around the cut surface after steel bar cutting. These burrs can easily cut operators, especially when handling or installing steel bars. Burrs may scratch the skin or even cause more serious injuries. Furthermore, burrs can cause stress concentration, affecting the mechanical properties of the steel bars and reducing their load-bearing capacity. During the connection process, burrs can also affect the connection quality, potentially leading to weak connections and compromising structural safety. Therefore, workers need to perform a secondary deburring operation on the cut steel bars, which increases their labor intensity and reduces overall work efficiency. To address these issues, a steel bar cutting device is proposed. Utility Model Content

[0023] like Figure 1-4 As shown, a rebar cutting device includes a base 1 and a controller 2. The controller 2 is fixedly connected to one end of the base 1, and a first support frame 3 and a second support frame 4 are fixedly connected to the top of the base 1. A second electric telescopic rod 8 is fixedly connected to one end of the first support frame 3, and a connecting plate 9 is fixedly connected to the bottom end of the second electric telescopic rod 8. A first motor 10 is fixedly connected to one end of the connecting plate 9, and a cutting disc 11 is fixedly connected to the end of the main shaft of the first motor 10. A limit mechanism is provided at one end of the second support frame 4, and two grinding mechanisms are fixedly connected to one end of the base 1. A ramp 26 is provided on the top surface of the base 1 located on one side of the second support frame 4. Guide plates 5 are fixedly connected to both ends of the second support frame 4 and are fixedly connected to the base 1. The ramp 26 facilitates the downward sliding of the cut rebar, while the guide plates 5 provide support for the cut rebar, ensuring that the cut rebar slides down stably.

[0024] As a further improvement to this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the grinding mechanism includes a limiting frame 18 fixedly connected to the base 1. One end of the limiting frame 18 is provided with an adjustment component, and one end of the adjustment component is fixedly connected to a third motor 22. The end of the main shaft of the third motor 22 is fixedly connected to a cleaning cover 23. The inner side of the cleaning cover 23 is fixedly connected to bristles 24, which are made of steel wire. After the steel bar is cut off, the cleaning covers 23 on both sides, along with the bristles 24, cover both ends of the steel bar. Then, the third motor 22 rotates rapidly at both ends of the steel bar with the cleaning covers 23 and the bristles 24, so that the cleaning covers 23 and the bristles 24 can quickly clean the burrs at both ends of the steel bar. When cutting another steel bar, it will not affect the cleaning of the burrs at both ends of the cut steel bar. No secondary operation is required, which facilitates the work of the workers and improves the overall work efficiency.

[0025] As a further improvement to this utility model, such as Figure 1 , Figure 2As shown, the adjustment assembly includes a second motor 19 fixedly connected to the limiting frame 18. A screw 20 is fixedly connected to the end of the main shaft of the second motor 19, and the screw 20 is rotatably connected to the limiting frame 18. A slider 21 is spirally connected to the outer side of the screw 20, and the slider 21 is fixedly connected to the third motor 22. A guide shaft 25 is slidably connected to the inner side of the slider 21, and the guide shaft 25 is fixedly connected to the limiting frame 18. Under the interaction of the screw 20 and the slider 21, the position of the cleaning cover 23 can be adjusted so that the cleaning cover 23 can cover the end of the reinforcing bar.

[0026] As a further improvement to this utility model, such as Figure 1 , Figure 4 As shown, the limiting mechanism includes a connecting column 12 fixedly connected to the second support frame 4. A baffle 15 is rotatably connected to the other end of the connecting column 12. A fourth electric telescopic rod 16 is fixedly connected to one end of the baffle 15. A pressure plate 17 is fixedly connected to one end of the fourth electric telescopic rod 16, and the pressure plate 17 is slidably connected to the baffle 15. A third electric telescopic rod 13 is rotatably connected to one end of the connecting column 12, and a side plate 14 is rotatably connected to the other end of the third electric telescopic rod 13. The side plate 14 is fixedly connected to the baffle 15. The pressure plate 17 can be used to press and limit the rebar, ensuring the stability of the rebar when cleaning the burrs at both ends. By adjusting the position of the baffle 15, the rebar can automatically fall from the slope to the ground, realizing automatic unloading.

[0027] As a further improvement to this utility model, such as Figure 1 As shown, a first electric telescopic rod 6 is fixedly connected to one end of the first support frame 3, and a clamping plate 7 is fixedly connected to the bottom end of the first electric telescopic rod 6. The first electric telescopic rod 6 can clamp and limit the steel bar with the clamping plate 7 to ensure the stability of the steel bar during cutting.

[0028] Workflow: When rebar needs to be cut, position the rebar below the cutting disc 11. Then, controller 2 controls the first electric telescopic rod 6, which, along with clamping plate 7, clamps and fixes the rebar. The first motor 10 then rotates the cutting disc 11, while the second electric telescopic rod 8, via connecting plate 9, moves the cutting disc 11 downwards to cut the rebar. The cut rebar falls onto the ramp 26 and guide plate 5, then slides down the ramp 26 and guide plate 5 to one side of baffle 15. The fourth electric telescopic rod 16, along with pressure plate 17, presses and limits the rebar. Next, the second motor 19, along with screw 20, rotates spirally inside slider 21, causing slider 21 to move via third motor 22, which in turn moves the cleaning cover 2. The cleaning cover 23 and brush 24 are placed on the end of the rebar. At the same time, the third motor 22 will also drive the cleaning cover 23 and brush 24 to rotate quickly at the end of the rebar. This allows the cleaning cover 23 and brush 24 to quickly clean the burrs at both ends of the rebar. When cutting another rebar, it will not affect the cleaning of the burrs at both ends of the cut rebar. No secondary operation is required, which is convenient for the workers and improves the overall work efficiency. After cleaning, the pressure plate 17 is separated from the rebar. At the same time, the third electric telescopic rod 13 pulls the baffle 15 through the side plate 14 to rotate around one end of the connecting column 12, so that the baffle 15 rotates upward. Then the rebar with the burrs at both ends cleaned will fall to the ground through the gap between the baffle 15 and the base 1.
