Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a rebar bending device for rapid positioning. Background Technology

[0002] Reinforcing steel is a commonly used high-strength steel material in construction engineering. By adding reinforcing steel to concrete, the tensile strength and overall stability of the structure can be significantly improved. It is a core material for modern buildings, bridges, roads and other infrastructure. Reinforcing steel bending is the process of bending reinforcing steel into specific shapes (such as L-shape, U-shape, ring, etc.) by mechanical or manual means to meet the design requirements of building structures.

[0003] A search revealed Chinese patent CN221675645U, which discloses a rebar bending device. This device addresses the issue that when bending the same type of rebar, the front and rear positions of the rebar must be calibrated to ensure accurate bending. It also addresses the limitations of quickly locating the bending point when bending the same type of rebar and the inability to operate without power. This new device enables rapid positioning of the bending point for the same type of building rebar, avoiding the need for re-positioning when bending the same type of rebar. Through the coordination of the bending mechanism, the driving mechanism, and the electric power mechanism, it can bend building rebar both with and without power, improving the device's practicality.

[0004] The aforementioned bending device facilitates quick positioning of reinforcing bars, but it is only suitable for bending reinforcing bars at one angle. In construction engineering, different bending angles are usually required when bending reinforcing bars, such as "U-shaped," "V-shaped," and "L-shaped." However, the existing technology is only convenient for "U-shaped" and "L-shaped" bending of reinforcing bars, and it is not convenient to select "V-shaped" bending as needed. Different bending devices with different shapes are required to perform "V-shaped" bending, which is quite troublesome and easily leads to low bending efficiency. Furthermore, when bending multiple reinforcing bars at the same time, it is difficult to align one end of multiple reinforcing bars. If one end of the reinforcing bars is not aligned, it is easy to cause deviations in the bending points of different reinforcing bars of the same size, reducing the bending accuracy.

At the same time, it also facilitates the quick replacement of the U-shaped block and V-shaped block when they are damaged, thus facilitating the smooth progress of bending work.

A bending column 7 is fixedly connected to the output end of the hydraulic cylinder 6. A limit component is provided inside the mounting plate 1. The bending column 7 facilitates the compression of the rebar, so that the rebar is bent.

[0034] The limiting support component includes a fixing plate 8, which is fixedly connected inside the mounting plate 1 to facilitate the installation of the positioning plate 10.

[0035] As attached Figure 1 As shown, a groove 9 is provided on the upper surface of the fixing plate 8 for the sliding of the slider 12.

[0036] As attached Figure 3 As shown, a slider 12 is slidably connected inside the slide groove 9, and a positioning plate 10 is fixedly connected to the upper surface of the slider 12. A threaded hole 11 is opened inside the positioning plate 10. When the positioning plate 10 is aligned and tightly attached to one end of multiple steel bars, the bending angle of the multiple steel bars is consistent. The thread of the threaded hole 11 matches the thread of the stud 13.

[0037] As attached Figure 1As shown, a stud 13 is threaded inside the threaded hole 11. A knob 14 is fixedly connected to one end of the stud 13. A mounting groove 15 is provided in the middle of the mounting plate 1. A U-shaped block 20 and a V-shaped block 21 are provided in the middle of the upper surface of the mounting plate 1. The U-shaped block 20 is bent at a U-shaped angle, and the V-shaped block 21 is bent at a V-shaped angle.

[0038] As attached Figure 2 As shown, a stepper motor 16 is fixedly installed inside the mounting slot 15. A bidirectional lead screw 17 is fixedly connected to the output end of the stepper motor 16. Two mounting blocks 18 are connected to the external threads of the bidirectional lead screw 17. The external threads of the bidirectional lead screw 17 are opened in opposite directions. The mounting blocks 18 are used to connect the U-shaped block 20 and the V-shaped block 21.

[0039] As attached Figure 5 As shown, the mounting block 18 has a threaded groove 19 inside, which matches the thread of the bidirectional lead screw 17.

[0040] As attached Figure 4 As shown, quick-replacement components are provided on the lower surfaces of U-shaped block 20 and V-shaped block 21. The quick-replacement components include connecting grooves 22. Two connecting grooves 22 are respectively opened on the lower surfaces of U-shaped block 20 and V-shaped block 21 for mounting on the outside of mounting block 18.

[0041] As attached Figure 6 As shown, two columnar grooves 23 are provided on both sides of the mounting block 18, and a limiting groove 24 is provided between the two columnar grooves 23. A spring 25 is fixedly connected inside the columnar groove 23, and a pressing block 26 is fixedly connected to one end of the spring 25. A rubber block 27 is provided on one side of the pressing block 26. The columnar groove 23 facilitates the retraction of the pressing block 26, and the rubber block 27 increases the friction between the pressing block 26 and the connecting groove 22.

[0042] As attached Figure 7 As shown, a limiting block 28 is fixedly connected between the two extrusion blocks 26. The limiting block 28 is slidably connected inside the limiting groove 24, and the limiting block 28 facilitates limiting the movement position of the extrusion blocks 26.

[0043] Working principle: During bending, multiple steel bars to be bent are arranged vertically, passing through the inside of the fixing frame 2, between the U-shaped block 20 and the V-shaped block 21. Based on the required bending position of the steel bars, the position of the positioning plate 10 is first adjusted. Turning the knob 14 causes the stud 13 to rotate. Under the action of the threaded hole 11, the stud 13 moves out of the threaded hole 11, releasing the limiting position of the positioning plate 10. Then, the positioning plate 10 is moved, causing the slider 12 to slide inside the slide groove 9. After sliding to the appropriate position, the knob 14 is turned again to install the stud 13 into the threaded hole 11, so that one end of it presses against the fixing plate 8, fixing the positioning plate 10. Then, one end of each steel bar is pressed against the positioning plate 10. Finally, the stepper motor 16 is started. The output end drives the bidirectional lead screw 17 to rotate. Under the action of the opposite direction threads on the outside of the bidirectional lead screw 17, the mounting blocks 18 on both sides move closer to each other. Under the action of the mounting block 18 connecting with the U-shaped block 20 and the V-shaped block 21, the U-shaped block 20 and the V-shaped block 21 move closer to each other to clamp multiple steel bars. Then, the stepper motor 4 is turned on, and its output end drives the rotating plate 5 to rotate. The rotating plate 5 drives the hydraulic cylinder 6 and the bending column 7 to selectively move to one side of the U-shaped block 20 or the V-shaped block 21 according to the angle that the steel bar needs to be bent. If the steel bar needs to be bent into a V shape, the bending column 7 moves to one side of the U-shaped block 20, the hydraulic cylinder 6 is started, and its output end drives the bending column 7 to move down. Then, under the action of the stepper motor 4 driving the rotating plate 5 to rotate, the steel bar is bent.

[0044] When disassembling the U-shaped block 20 or the V-shaped block 21, the corresponding U-shaped block 20 or V-shaped block 21 that needs to be disassembled is moved upward to disassemble it. When installing, the U-shaped block 20 or the V-shaped block 21 is inserted into the outside of the mounting block 18 through the connecting groove 22, so that the pressing block 26, under the push of the spring 25, drives the rubber block 27 to press tightly against the inner wall of the connecting groove 22, thereby limiting the installation of the U-shaped block 20 or the V-shaped block 21.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
