Description

Technical Field

[0001] This utility model relates to the field of steel bar cutting technology, and more specifically, to a steel bar cutting device for building construction. Background Technology

[0002] The construction industry encompasses the design, construction, decoration, and management of buildings. Urban architecture is a crucial component of a city, and buildings are not merely man-made structures providing shelter, rest, and entertainment; they are deeply intertwined with our economy, culture, and daily life. Reinforcing steel refers to various steel bars and wires used in reinforced concrete. Reinforcing steel is categorized by steel type: non-alloy steel, low-alloy steel, and alloy steel. It is also classified by production process: hot-rolled, heat-treated, residual heat-treated, cold-rolled, and cold-drawn. Finally, it is classified by shape: plain round steel and deformed steel.

[0003] A search revealed that Chinese utility model patent application number CN202223238835.X discloses a steel bar cutting device for building construction, comprising: a base frame, an L-shaped frame B welded to the rear of the left side recess of the base frame, upper steel bar driving components installed at equal intervals inside the left side recess of the base frame, a lifting plate vertically and liftably mounted on the front of the L-shaped frame B, and three lower steel bar driving components installed at equal intervals at the bottom of the lifting plate.

[0004] When cutting steel bars required for construction, the device uses a drive motor to rotate the cutting blades, which then cut the steel bars. When the cut steel bars are short, the force of the rotating blades causes the short steel bars to be flung out. At the same time, the cutting process generates flying iron filings, which, along with the short steel bars, can easily injure nearby workers, making its use highly dangerous. In addition, the iron filings generated during steel bar cutting fall inside the horizontal box, making it difficult to clean. Furthermore, the large amount of iron filings affects the adjustment of the position of the reinforcing plate, reducing its practicality. Utility Model Content

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0029] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] Please see Figures 1-5A rebar cutting device for construction includes a base frame 1, a fixed frame 2 fixedly connected to the top of the base frame 1, two first electric cylinders 3 mounted on the fixed frame 2, an L-shaped seat 4 fixedly connected to the two first electric cylinders 3, a first motor 5 mounted on the L-shaped seat 4, and a cutting blade 6 mounted on the first motor 5. A protective cover 7 is slidably disposed on the outside of the fixed frame 2, two first fixing blocks 8 fixedly connected to the side of the protective cover 7, a second electric cylinder 9 mounted at the bottom of each of the two first fixing blocks 8, a second fixing block 10 fixedly connected to the bottom of each of the two second electric cylinders 9, and both second fixing blocks 10 fixedly connected to the side of the base frame 1. A baffle plate 11 is slidably disposed on the base frame 1, and a support platform 12 is fixedly connected to the side of the base frame 1. A rebar limiting component is disposed on the support platform 12 to limit the rebar and ensure that the rebar being cut is always located below the cutting blade 6.

[0031] Specifically, when cutting the reinforcing bars, the two second electric cylinders 9 pull the protective cover 7 downwards, and the protective cover 7 presses and fixes the reinforcing bars on both sides of the cutting blade 6. The first electric cylinder 3 pushes the L-shaped seat 4 downwards, and at the same time, the first motor 5 drives the cutting blade 6 to rotate. When the cutting blade 6 contacts the reinforcing bar, it cuts the reinforcing bar. Since the protective cover 7 covers the outside of the fixing frame 2 and presses and fixes the reinforcing bar, it can prevent the cut reinforcing bar from flying out and effectively prevent iron filings from flying everywhere. It can effectively prevent iron filings from causing injury to workers and improve the safety of cutting reinforcing bars.

[0032] Please see Figure 4 The base frame 1 has two fixedly connected first sliding grooves 13 on both sides of its bottom end. The two first sliding grooves 13 are each slidably provided with a first sliding block 14. One first sliding block 14 is threadedly connected to a first screw 15. The first screw 15 is rotatably connected to the base frame 1. A second motor 16 is installed on the side end of the base frame 1. The output end of the second motor 16 is fixedly connected to the side end of the first screw 15. L-shaped plates 17 are fixedly connected to the side ends of the two first sliding blocks 14. The baffle plate 11 is fixedly connected to the two L-shaped plates 17. A limit rod 18 is slidably provided on the other first sliding block 14. The limit rod 18 is fixedly connected to the base frame 1 and provides a limiting support effect for the corresponding first sliding block 14.

[0033] Specifically, the second motor 16 drives the first screw 15 to rotate. The rotation of the first screw 15 causes the corresponding first slide block 14 to slide inside the first slide groove 13. The first slide block 14 drives the L-shaped plate 17 and the baffle plate 11 to move, which facilitates the adjustment of the position of the baffle plate 11 and the adjustment of the distance between the baffle plate 11 and the cutting blade 6. This facilitates the setting of the length of the steel bar to be cut and helps to control the length of the steel bar cut more accurately. Since the two first slide grooves 13 are set at the bottom of the base frame 1, it can prevent iron filings from falling into the interior of the first slide grooves 13 and affecting the movement of the first slide block 14, making it easier for people to clean the iron filings on the base frame 1.

[0034] Please see Figures 1-5 The base frame 1 is provided with a material drop trough 19. Two support plates 20 are rotatably connected to the upper side of the inside of the material drop trough 19. Multiple third electric cylinders 21 are rotatably connected to the bottom of the two support plates 20. The bottom of the multiple third electric cylinders 21 are rotatably connected to the base frame 1. A cutting groove 22 is provided between the side ends of the two support plates 20 and the base frame 1. The position of the cutting groove 22 corresponds to the position of the cutting blade 6, so that the cutting blade 6 can be moved into the inside of the cutting groove 22 to cut the steel bar. A collection box 23 is placed below the material drop trough 19 to facilitate the collection of the cut steel bar. Multiple casters 24 with self-operating function are installed at the bottom of the collection box 23 to facilitate the movement of the collection box 23.

[0035] Specifically, after the steel bar is cut, multiple third electric cylinders 21 pull two support plates 20 downward to rotate. When the two support plates 20 rotate to a certain angle, the steel bar falls into the collection box 23 through the gap between the two support plates 20. The collection box 23 collects the cut steel bar, avoiding people from reaching under the cutting blade 6 to pick up the steel bar, avoiding contact between people's hands and the cutting blade 6, avoiding injury to workers, and reducing people's workload.

[0036] Please see Figure 2 The rebar limiting assembly includes two limiting plates 25. A second sliding groove 26 is provided on the side end of the support platform 12. A bidirectional screw 27 is rotatably connected inside the second sliding groove 26. Two second sliding blocks 28 are symmetrically threaded on the outside of the bidirectional screw 27. Both second sliding blocks 28 are slidably engaged with the second sliding groove 26. The two limiting plates 25 are fixedly connected to the two second sliding blocks 28 respectively. The bottom ends of the two second limiting plates 25 are in contact with the top end of the support platform 12. A third motor 29 is installed on the side end of the support platform 12. The output end of the third motor 29 is fixedly connected to the side end of the bidirectional screw 27.

[0037] Specifically, the third motor 29 drives the bidirectional screw 27 to rotate. The rotation of the bidirectional screw 27 causes the two second slide blocks 28 to move in opposite directions inside the second slide groove 26. The two second slide blocks 28 drive the two limiting plates 25 to move. The distance between the two limiting plates 25 is adjusted according to the thickness of the steel bar so that the steel bar is always in the position corresponding to the cutting blade 6.

[0038] In summary, when using the overall equipment:

[0039] The second motor 16 drives the first screw 15 to rotate, causing the corresponding first slide block 14 to slide inside the first slide groove 13. The first slide block 14 drives the L-shaped plate 17 and the baffle plate 11 to move, adjusting the position of the baffle plate 11 so that the distance between the baffle plate 11 and the cutting blade 6 is equal to the length of the steel bar to be cut. Then, the third motor 29 drives the bidirectional screw 27 to rotate, causing the two second slide blocks 28 to move in opposite directions inside the second slide groove 26. The two second slide blocks 28 drive the two limiting plates 25 to move, adjusting the distance between the two limiting plates 25 according to the thickness of the steel bar. The steel bar to be cut is placed between the two limiting plates 25 and pushed to move, so that the side end of the steel bar contacts the side end of the baffle plate 11. Then, the two second electric cylinders 9 pull the protective cover 7 downward, pressing and securing the steel bars on both sides of the cutting blade 6 through the protective cover 7. The first electric cylinder 3 pushes the L-shaped seat 4 downward, while the first motor 5 drives the cutting blade 6 to rotate. When the cutting blade 6 contacts the rebar, it cuts the rebar. After the rebar is cut, multiple third electric cylinders 21 pull the two support plates 20 downward. When the two support plates 20 rotate to a certain angle, the rebar falls into the collection box 23 through the gap between the two support plates 20. The collection box 23 collects the cut rebar. Then, multiple third electric cylinders 21 push the support plates 20 upward. When the third electric cylinders 21 extend to their longest position, the top surface of the support plate 20 is flush with the top surface of the base frame 1. Then, the first electric cylinder 3 and the second electric cylinder 9 move the L-shaped seat 4 and the protective cover 7 upward respectively. Then, the rebar is pushed to the position where it contacts the baffle plate 11. Then, the protective cover 7 presses and fixes the rebar, and the rebar continues to be cut.

For all the fixed connections mentioned above, welding is preferred.
