A cutting blade is rotatably mounted on the mounting frame, and a handle is fixed to the extended end of the push rod. A spring is provided between the handle and the cutting box. A sealing plate is slidably embedded in the upper end of the cutting box, and a transparent window is provided on the sealing plate. An exhaust fan is also mounted on the base, and a connecting pipe connects the exhaust fan to the inside of the cutting box. This rebar cutting device for building construction can achieve closed-loop cutting of rebar, avoiding flying debris that could injure operators, ensuring high safety. It also allows for direct observation of the cutting status of the rebar, ensuring cutting quality. The exhaust fan collects the waste gas and debris generated during the cutting process, preventing environmental pollution and ensuring cleanliness and hygiene.

[0004] However, the aforementioned rebar cutting device does not have a limiting function for the rebar to be cut when cutting the rebar, which makes the rebar prone to displacement, shaking and other unstable situations during the cutting process. This not only affects the cutting accuracy, but also causes the rebar cut to be uneven and the dimensions to be deviated. Therefore, a rebar cutting device for building construction is proposed to solve the above problems. Utility Model Content

[0027] like Figure 1-5 As shown, the present invention proposes a steel bar cutting device for building construction, including a base plate 9, a cutting box 6 on the upper surface of the base plate 9, and a cutter 18 connected to the rear side of the inner wall of the cutting box 6 via a third electric push rod 16. First mounting grooves 15 are provided on the upper sides of both sides of the outer end face of the cutting box 6. Alignment blocks 4 are provided on the upper surface of the base plate 9 and on both sides of the cutting box 6. Limiting grooves 3 are provided on the upper surface of the alignment blocks 4. Limiting mechanisms are provided on the upper surface of the base plate 9 and above the alignment blocks 4 on both sides. A second mounting groove 20 is provided inside the base plate 9, and the second mounting groove 20 is connected to the interior of the cutting box 6. A collecting component is provided inside the second mounting groove 20. The bottom of the limiting grooves 3 on the upper end of the alignment blocks 4 on both sides is on the same plane as the bottom of the first mounting grooves 15 on both sides.

[0028] In this invention, when in use, the steel bar to be cut is first placed on the limiting groove 3 at the upper end of the two side alignment blocks 4. At this time, the steel bar is located in the first mounting groove 15 on both sides. Then, the limiting mechanism on both sides is activated to limit the steel bar to be cut. Then, the third electric push rod 16 is activated, which can drive the activated cutter 18 to move, thereby cutting the steel bar to be cut. The waste generated by cutting will fall into the collection component inside the second mounting groove 20. When there is a lot of waste, the collection component can be taken out and cleaned.

[0029] In an optional embodiment, the limiting mechanism includes a second electric push rod 5, a lifting plate 10, and a limiting component. The upper end surface of the base plate 9, located on both the front and rear sides of the alignment block 4, is connected to the second electric push rod 5. The lifting plate 10 is located at the upper end of the second electric push rod 5. The opposite sides of the two lifting plates 10 are connected to the limiting component. The limiting component includes a moving plate 1, a first electric push rod 2, and a limiting block 11. The side of the lifting plate 10 near the central axis of the limiting groove 3 is connected to the limiting block 11 through the first electric push rod 2.

[0030] It should be noted that when the reinforcing bar is placed on the limiting groove 3, the first electric push rod 2 located on the front and rear sides of the alignment block 4 is activated first, so that the first electric push rod 2 on both sides drives the limiting block 11 to move closer to each other. At this time, the second electric push rod 5 on both sides retracts, so that the lifting plate 10, the moving plate 1, the first electric push rod 2 and the limiting block 11 connected to it can move downward, thereby limiting the reinforcing bar.

[0031] In an optional embodiment, a plurality of slide rods 12 are also included. A plurality of sliding grooves 19 are provided on the limiting block 11. The plurality of slide rods 12 are distributed at intervals on the side of the moving plate 1 near the central axis of the alignment block 4. The plurality of slide rods 12 are respectively inserted into the interior of the plurality of sliding grooves 19 that are adapted to them.

[0032] It should be noted that when the movable plate 1 moves, the multiple sliding rods 12 will move inside the multiple sliding grooves 19 respectively, thereby ensuring the stability of the limit block 11 when it moves.

[0033] In an optional embodiment, the collection component includes a first handle 7 and a collection box 8, the opening of the collection box 8 facing upwards, the first handle 7 being located on the front end face of the collection box 8, and the opening of the collection box 8 being larger than the internal space of the cutting box 6.

[0034] It should be noted that the cut impurities can fall into the collection box 8. When there are many impurities inside the collection box 8, the first handle 7 can be used to easily pull the collection box 8 out from the second mounting slot 20, and then clean the impurities inside the collection box 8. After the collection box 8 is cleaned, it can be put back into the second mounting slot 20.

[0035] In an optional embodiment, an outer frame 14 is also included, which is hinged to the rear side of the upper edge of the cutting box 6. The inner end face of the outer frame 14 is provided with transparent glass 13, and the front end face of the outer frame 14 is provided with a second handle 21.

[0036] It should be noted that when it is necessary to cut the steel bars, the outer frame 14 is rotated by the second handle 21 so that the outer frame 14 contacts the upper surface of the cutting box 6. At this time, the steel bars being cut can be separated by the transparent glass 13 to prevent the sparks generated during cutting from splashing out; and the cutting of the steel bars can also be observed through the transparent glass 13.

[0037] In an optional embodiment, a laser emitter 17 is provided on the front inner wall of the cutting box 6, and the laser emitted by the laser emitter 17 is on the same straight line as the cutting end of the cutter 18.

[0038] It should be noted that after the steel bars are placed, the laser emitted by the laser emitter 17 will be emitted onto the steel bars, thus ensuring the position of the steel bars that needs to be cut.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
