Description

Technical Field

[0001] This application relates to the technical field of steel bar processing, and in particular to a steel bar length-cutting device. Background Technology

[0002] Reinforcing steel refers to steel used in reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. Reinforcing steel is widely used in civil engineering construction, including buildings, bridges, and roads. From public facilities such as highways, railways, bridges, culverts, tunnels, flood control systems, and dams, to the foundations, beams, columns, walls, and slabs of buildings, reinforcing steel is an indispensable structural material. Therefore, different applications require different lengths of reinforcing steel, necessitating workers to cut and fix the steel to the required length.

[0003] Currently, steel bar cutting requires manual or semi-automatic cutting by workers. Manual cutting requires manual pressing or pushing of the cutting tool, which is time-consuming and labor-intensive, and it is difficult to produce steel bars of the same length and uniform specifications in a short time. Semi-automatic cutting requires workers to lift the steel bars onto the cutting machine. When unloading, manual material placement and loading are required, which is physically demanding and poses safety hazards.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0027] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0028] This application discloses a rebar cutting device for fixed length cutting. For example... Figure 1 , Figure 2 , Figure 3 As shown, the support includes a support platform 1. A limit groove 3 is formed on the upper surface of the support platform 1. A scale plate 2 is fixedly connected to the front of the support platform 1. Two support plates 1 (5) and two support plates 2 (4) are fixedly connected to both the front and back of the support platform 1. A threaded long rod 6 is rotatably connected between each support plate 1 (5) and support plate 2 (4). A roller 7 is fixedly connected to the left end of each threaded long rod 6. A movable slider 15 is threadedly connected to the outer surface of each threaded long rod 6. A movable support plate 11 is fixedly connected between the two movable sliders 15. Two fixed push plates 12 are fixedly connected to the bottom surface of the movable support plate 11. Support short shafts 16 are fixedly connected to the opposite surfaces of the two fixed push plates 12. A rotating push plate 17 is rotatably connected to the outer surface of each support short shaft 16. The opposing surfaces of the push plate 12 are provided with arc-shaped grooves 18. An arc-shaped spring 19 is fixedly connected between the inner wall of each arc-shaped groove 18 and the corresponding rotating push plate 17. A rectangular push block 13 is fixedly connected to the upper surface of the movable support plate 11. Four triangular reinforcing plates 14 are fixedly connected between the rectangular push block 13 and the upper surface of the movable support plate 11. When it is necessary to feed the steel bars, the reel 7 rotates to drive the corresponding threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the movable slider 15, which in turn drives the movable support plate 11. The movable support plate 11 drives the two fixed push plates 12 below, which in turn drive the corresponding rotating push plates 17 to move, so that the two rotating push plates 17 clamp the steel bars and move with the movement of the fixed push plates 12.

[0029] like Figure 2 , Figure 3As shown, a motor 9 is embedded on the left side of the support platform 1. The output shaft of the motor 9 is fixedly connected to a transmission wheel 10. When the motor 9 is started, the output shaft of the motor 9 drives the transmission wheel 10, and the transmission wheel 10 drives the transmission track 8 to rotate. The output shaft of the motor 9 can rotate in both directions.

[0030] like Figure 2 , Figure 3 As shown, a transmission track 8 is connected to the outer surface of the transmission wheel 10. The transmission track 8 is connected to two rollers 7, and the transmission track 8 drives the two rollers 7 to rotate.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, a movable short plate 20 is provided above the support platform 1. Two movable adjustment blocks 27 are fixedly connected to the bottom surface of the movable short plate 20. Threaded short rods 35 are fixedly connected to the surfaces of the two movable adjustment blocks 27 that are far apart from each other. Rollers 34 are rotatably connected to the surfaces of the two movable adjustment blocks 27 that are far apart from each other. A pressing rotating block 36 is threadedly connected to the outer surface of each threaded short rod 35. The movable short plate 20 is pushed according to the length of the steel bar to be cut, so that the movable short plate 20 drives the indicator plate 33 to move to the required position. The pressing rotating block 36 is rotated to press the outer surface of the support platform 1 to prevent the movable short plate 20 from sliding. At this time, the movable support plate 11 drives the steel bar and the rectangular push block 13 to move towards the cutting block 21. When the rectangular push block 13 contacts the inclined plane 24, it pushes the cutting block 21 downward along the inclined plane 24.

[0032] like Figure 1 , Figure 5 As shown, positioning track plates 32 are fixedly connected to the surfaces of the two movable adjustment blocks 27 that are close to each other. Telescopic positioning blocks 29 are slidably connected to the outer surface of the positioning track plates 32. Each movable adjustment block 27 has a cavity 28 inside. A short piece 30 is fixedly connected to the right side of each telescopic positioning block 29. A contraction spring 31 is fixedly connected between each short piece 30 and the inner wall of the corresponding cavity 28. When the movable support plate 11 approaches the movable short piece 20, the movable support plate 11 pushes the telescopic positioning block 29 to contract, and the telescopic positioning block 29 pulls the contraction spring 31 through the short piece 30. When the telescopic positioning block 29 is no longer pushed, the contraction spring 31 pushes the telescopic positioning block 29 to reset through the short piece 30. The purpose of setting the telescopic positioning block 29 is to leave a small section between the two telescopic positioning blocks 29 after the steel bar is cut by the cutting block 21, so as to prevent the steel bar from not passing under the cutting block 21 during the next cutting.

[0033] like Figure 1 , Figure 4 , Figure 5As shown, a cutting block 21 is slidably connected inside the movable short plate 20. A reset plate 23 is fixedly connected to both the front and back of the cutting block 21. An inclined surface 24 is provided on the upper surface of the cutting block 21. Two circular grooves 22 are provided on the upper surface of the movable short plate 20. A support spring 25 is fixedly connected between the inner wall of each circular groove 22 and the reset plate 23. The cutting block 21 moves down to cut the steel bar. After cutting, the support spring 25 drives the cutting block 21 to move upward through the reset plate 23 to reset.

[0034] like Figure 2 , Figure 3 , Figure 4 As shown, a sensing block 26 is fixedly connected to the upper surface of the movable short plate 20, a baffle 37 is fixedly connected to the left side of the movable short plate 20, and a supporting short block 38 is fixedly connected to the left side of the baffle 37. When the sensing block 26 and the rectangular push block 13 come into contact, an electrical signal is generated, causing the motor 9 to start to rotate, so that the movable support plate 11 moves away from the movable short plate 20. The function of the supporting short block 38 is to open up the two rotating push plates 17 to prevent the cutting block 21 from pushing the steel bar to move during cutting.

[0035] like Figure 1 , Figure 4 As shown, an indicator plate 33 is fixedly connected to the front of the movable short plate 20. The indicator plate 33 is slidably connected to the outer surface of the scale plate 2. The cutting length of the steel bar can be clearly known according to the position of the indicator plate 33 on the scale plate 2.

[0036] The implementation principle of the rebar length-cutting device in this embodiment is as follows: The moving short plate 20 is pushed according to the desired rebar length, causing the indicator plate 33 to move to the required position. The rotating extrusion block 36 is rotated to press against the outer surface of the support platform 1, preventing the moving short plate 20 from sliding. The cutting length of the rebar can be clearly determined based on the position of the indicator plate 33 on the scale plate 2. The motor 9 is started, causing its output shaft to drive the transmission wheel 10, which in turn drives the transmission track 8 to rotate. The output shaft of the motor 9 can rotate in both directions. When rebar needs to be fed, the coil 7 rotates, driving the corresponding threaded rod 6 to rotate. 6. Rotating the slider 15 causes it to move the support plate 11, which in turn moves the two fixed push plates 12 below. The fixed push plates 12 then move the corresponding rotating push plates 17, which clamp the reinforcing bars. As the fixed push plates 12 move, the support plate 11 moves the reinforcing bars and the rectangular push block 13 toward the cutting block 21. When the rectangular push block 13 contacts the inclined plane 24, it pushes the cutting block 21 downward along the inclined plane 24. The cutting block 21 moves downward to cut the reinforcing bars. After cutting, the support spring 25 moves the cutting block 21 upward through the reset plate 23 to reset it.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
