Description

Technical Field

[0001] This utility model relates to the field of rebar bending machine technology, and more specifically, to a locking device for a rebar bending machine used in building construction. Background Technology

[0002] A rebar bending machine is a type of rebar processing machinery. Its working mechanism is a horizontal working disc that rotates on a vertical axis. The rebar is placed at the position shown by the dotted line in the diagram. The support pin is fixed on the machine tool, and the center pin and the bending pin are mounted on the working disc. When the disc rotates, it bends the rebar.

[0003] To ensure the stability of rebar bending, existing rebar bending machines are generally equipped with locking devices. However, these devices can only lock one position on the rebar, resulting in excessive pressure during locking and making the locking devices prone to damage. In addition, some rebars have a small amount of rust on the outside, which the existing devices cannot remove. This means that the rebars need to be derusted before or after bending, increasing the number of steps and reducing work efficiency.

[0004] In view of this, we propose a locking device for a steel bar bending machine used in building construction. Utility Model Content

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A locking device for a rebar bending machine used in construction includes a bending machine body 1. A fixing frame 2 is fixedly mounted on the upper side of the bending machine body 1. An installation box 3 is fixedly mounted inside the fixing frame 2. A threaded rod 4 is rotatably mounted inside the installation box 3. Two sections of threads in opposite directions are provided on the outer side of the threaded rod 4, and threaded blocks 5 are fitted on each of the two sections of threads in opposite directions on the outer side of the threaded rod 4. U-shaped blocks 6 are fixedly mounted on the outer side of each set of threaded blocks 5. A limit roller 7 is rotatably mounted inside the U-shaped blocks 6. A limit groove 8 is formed on the outer side of the limit roller 7. The threaded rod 4 is movable. The rotating rod 4 extends through the mounting box 3 and outwards, and a turntable 9 is fixedly installed on the outer end of the threaded rod 4 located on the outer part of the mounting box 3. A movable box 10 is movably installed on the outer side of the bending machine body 1. Two sets of arc-shaped blocks 14 are movably installed on the upper side of the movable box 10. Grinding blocks 15 are fixedly installed on the inner side of both sets of arc-shaped blocks 14. The two sets of limiting rollers 7 can firmly clamp the steel bar to prevent the steel bar from shifting during bending. At the same time, the rotation of the limiting rollers 7 can facilitate the movement of the steel bar, thereby ensuring the convenience of bending the steel bar.

[0028] Specifically, two sets of mounting blocks 12 are movably arranged inside the movable box 10. A connecting rod 13 is fixedly arranged on the outer side of each set of mounting blocks 12. The connecting rod 13 movably passes through the movable box 10 and extends to the outside. The outer end of the connecting rod 13 is fixedly connected to the arc-shaped block 14 on the outer side of the movable box 10. Two sets of springs 16 are arranged inside the movable box 10. One end of each set of springs 16 is connected to the two sides of the movable box 10, and the other end of each spring 16 is connected to the mounting block 12. The springs 16 do not deform in the initial state. When bending the steel bar, the two sets of arc-shaped blocks 14 need to be separated. Then the steel bar is placed between the two sets of arc-shaped blocks 14. Then, through the release of the elastic potential energy of the spring, the two sets of arc-shaped blocks 14 can be driven to quickly fit against the outer side of the steel bar, improving the convenience of limiting the position of the steel bar. While facilitating the horizontal movement of the steel bar, it is also convenient to clean the rust on the outer side of the steel bar.

[0029] Furthermore, a slide bar 11 is fixedly installed inside the movable box 10. The slide bar 11 moves through the mounting block 12 and can limit the mounting block 12, so that the mounting block 12 moves along the slide bar 11, ensuring the stability of the movement of the mounting block 12.

[0030] It is worth noting that the inner side of the mounting box 3 is provided with a sliding groove 17 for mating threaded block 5. The threaded block 5 slides within the sliding groove 17, which limits the movement of the threaded block 5. This allows the threaded block 5 to move parallel to the threaded rod 4 when the threaded rod 4 rotates, thereby improving the movement stability of the threaded block 5.

[0031] It is worth noting that a movable block 18 is movably arranged inside the movable box 10, and a connecting block 19 is rotatably arranged on both sides of the movable block 18. The two sets of connecting blocks 19 are rotatably connected to the two sets of mounting blocks 12 respectively, and a movable rod 20 is fixedly arranged on the outside of the connecting block 19. The movable rod 20 moves through the movable box 10 and extends to the outside. A handle 21 is fixedly arranged on the outer end of the movable rod 20 located on the outer part of the movable box 10. By pressing the handle 21, the two sets of arc-shaped blocks 14 can be easily and quickly separated, thereby facilitating the quick clamping of the steel bars and improving the ease of use.

[0032] In addition, a fixed block 22 is fixedly installed on the outside of the bending machine body 1, and an electric push rod 23 is installed on the outside of the fixed block 22. One end of the electric push rod 23 is connected to the fixed block 22, and the other end of the electric push rod 23 is connected to the movable box 10. By turning on the electric push rod 23 with an external power source, the movable box 10 can be easily moved up or down, thereby facilitating the adjustment of the position of the arc block 14 and meeting various usage needs.

[0033] Working principle: First, pressing the handle 21 moves the movable rod 20 and the movable block 18. The movement of the movable block 18 moves the connecting blocks 19 on both sides. The movement of the connecting blocks 19 moves the mounting block 12 and the connecting rod 13. The movement of the connecting rod 13 moves the arc-shaped block 14 and the grinding block 15. Then, the reinforcing bar is passed between the two sets of grinding blocks 15 and the two sets of limiting rollers 7. Next, the handle 21 is released, and the rebound force of the spring 16 causes the two sets of grinding blocks 15 to adhere to the outside of the reinforcing bar. Then, the handle is rotated... The disc 9 drives the threaded rod 4 to rotate. At this time, the two sets of threaded blocks 5, which are sleeved on the outside of the threaded rod 4, move simultaneously and approach each other under the left and right limit of the slide groove 17. When the threaded blocks 5 move, they drive the U-shaped block 6 and the limiting roller 7 to move until the two sets of limiting roller 7 clamp the steel bar. Then the steel bar can be moved for bending. During the bending process, the two sets of grinding blocks 15 can remove the rust on the outside of the steel bar. The two sets of limiting roller 7 not only facilitate the locking of the steel bar, but also facilitate the movement and bending of the steel bar, thus improving the bending efficiency of the steel bar.
