Description

Technical Field

[0001] This utility model relates to the field of steel bar bending technology, and in particular to an adjustable angle steel bar bending device for building construction. Background Technology

[0002] Steel bars used in building construction are the core reinforcing materials in concrete structures. They are usually hot-rolled or cold-rolled ribbed steel bars. The crescent-shaped or spiral ribs distributed on their surface can significantly improve the bond strength with concrete and prevent slip cracking. According to design requirements, they are used to form a skeleton through binding, welding or mechanical connection such as straight threaded sleeves to bear the combined tensile, compressive, bending and shear stresses of the building.

[0003] Rebar bending devices are used in building construction because they can bend rebar into specific shapes according to design requirements, precisely matching the needs of the building structure. This device can improve construction efficiency, ensure stable rebar bending quality, reduce errors, enhance the stability and safety of the building structure, and guarantee the quality of building construction. Existing rebar bending devices used in building construction are usually fixed mechanical structures, with the angle predetermined by the geometry of the mold. They cannot be adjusted according to construction needs, resulting in the need to equip multiple sets of molds to cope with different angles, increasing costs and operational complexity. At the same time, their limiting mechanism usually uses rigid blocks or fixed bolts for positioning, lacking scale adjustment functions. The bending length needs to be manually measured and marked, and dimensional deviations are easily caused by block wear or bolt loosening, affecting the rebar processing accuracy and making it difficult to meet the requirements of modern building standardization and efficient construction.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1:

[0026] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an adjustable angle steel bar bending device for building construction, including a processing table 1 and a driving component 2. The driving component 2 is provided at the bottom of the processing table 1, and a bending disc 3 is fixed at the top of the driving component 2. A bending mechanism 4 is provided inside the bending disc 3, and a bending wheel 5 is provided on the outside of the bending mechanism 4. A connecting component 6 is provided inside the bending disc 3, and a limiting disc 7 is provided at the top of the connecting component 6. A support frame 8 is fixed at the top of the processing table 1. An adjusting component 9 is provided inside the support frame 8, and a guide plate 10 is provided on the outside of the adjusting component 9. A limiting mechanism 11 is provided on one side of the guide plate 10. A fixing frame 12 is fixed at the top of the processing table 1, and a guide roller 13 is rotatably connected to the inner wall of the fixing frame 12.

[0027] In the steel bar bending operation during building construction, the bending mechanism 4 is first adjusted to the position of the corresponding bending disc 3 so that the bending wheel 5 is adjusted to the preset bending angle. The driving component 2 drives the bending disc 3 to rotate, and the bending disc 3 drives the bending mechanism 4 to rotate, so that the bending wheel 5 applies force to bend the steel bar in the limiting disc 7. During this process, the relative position between the bending disc 3 and the limiting disc 7 is maintained by the connecting component 6 to achieve the effect of angle adjustment. In terms of limiting, the adjusting component 9 drives the two sets of guide plates 10 to move towards each other. The guide plates 10 then push the limiting mechanism 11 to fit tightly against the surface of the steel bar, effectively preventing the steel bar from shifting during the bending process and ensuring the quality of bending. During the bending process, the steel bar is placed on the guide roller 13, and the guide roller 13 rolls with the movement of the steel bar to guide the steel bar, ensuring that the steel bar moves along the preset path and reducing the frictional resistance between the steel bar and the processing table 1.

[0028] It should be noted that: the inner wall of the bending disc 3 is provided with multiple mounting holes 41. By working with the bending rod 42, the installation position of the bending rod 42 can be flexibly adjusted according to the bending requirements of the steel bars, so as to realize various bending angles and shapes of steel bars of different specifications. Two sets of guide plates 10 are provided. By working with the bidirectional screw 91, the two sets of guide plates 10 can be driven to move towards or away from each other by rotating the bidirectional screw 91. The spacing can be flexibly adjusted according to the size of the steel bars, so as to effectively limit the steel bars.

[0029] The bending mechanism 4 includes a mounting hole 41 opened in the inner wall of the bending disk 3. A bending rod 42 is inserted into the inner wall of the bending disk 3 through the mounting hole 41, and the outer side of the bending rod 42 is rotatably connected to the inner wall of the bending wheel 5.

[0030] In terms of adjusting the bending angle, by inserting the bending rod 42 into the corresponding mounting hole 41, the bending wheel 5 is adjusted to the preset bending angle. It can be positioned according to different steel bar specifications and bending requirements, realizing flexible bending processing of various steel bars. This avoids the need to adjust the steel bars or replace the device multiple times due to the fixed bending angle, thus improving processing efficiency.

[0031] The limiting mechanism 11 includes a limiting plate 111 fixed to one side of the guide plate 10, and a limiting ring 112 fixed to one side of the limiting plate 111.

[0032] By pushing the limiting plate 111 with the guide plate 10, the two sets of limiting rings 112 are finally tightly attached to the surface of the steel bar. The limiting position can be adjusted adaptively according to the thickness of the steel bar, thus achieving effective fixing and limiting of the steel bar and preventing displacement or shaking of the steel bar during bending.

[0033] Example 2:

[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the driving component 2 includes a motor 21 fixed to the bottom of the processing table 1. A guide rod 22 is fixed to the output end of the motor 21, and the outer side of the guide rod 22 is rotatably connected to the inner wall of the processing table 1. One end of the guide rod 22 is fixed to the bottom of the bending disk 3.

[0036] When bending the steel bars, the guide rod 22 is driven to rotate by the motor 21. The guide rod 22 drives the bending disc 3 and the bending rod 42 to rotate, so that the bending wheel 5 applies force to the steel bars in the limiting disc 7 and bends them. This realizes the automated bending operation, improves efficiency, avoids the instability of manual operation, and ensures the stability of bending angle and quality.

[0037] Specifically, the connector 6 includes a ball bearing 61 that is rolled to the inner wall of the bending disk 3. A connecting shaft 62 is rolled to the outer side of the ball bearing 61. The bottom of the connecting shaft 62 is rotatably connected to the inner wall of the bending disk 3, and the top of the connecting shaft 62 is fixed to the bottom of the limiting disk 7.

[0038] When the guide rod 22 drives the bending disk 3, since the bending disk 3 is connected to the rolling ball 61 and the rolling ball 61 is also connected to the rotating shaft 62, and the rotating shaft 62 is also connected to the bending disk 3, the rolling ball 61 reduces friction, making the rotation of the bending disk 3 smoother, limiting the swaying or offset of the connecting shaft 62 relative to the bending disk 3 in the non-rotational direction, and ensuring the stability of operation.

[0039] Specifically, the adjusting component 9 includes a bidirectional screw 91 rotatably connected to the inner wall of the support frame 8, and the outer side of the bidirectional screw 91 is threadedly connected to the inner wall of the guide plate 10. One end of the bidirectional screw 91 is fixed with a turntable 92.

[0040] The rotating turntable 92 drives the bidirectional screw 91 to rotate, which in turn drives the two sets of guide plates 10 to move in opposite directions. The distance between the two can be flexibly adjusted according to the thickness of the steel bars, so as to effectively clamp and limit the steel bars of different specifications.

[0041] Example 3:

[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, a connecting rod 14 is fixed to one side of the limiting plate 111, and a connecting column 15 is slidably connected to the outside of the connecting rod 14, with one end of the connecting column 15 fixed to one side of the support frame 8.

[0044] When the guide plate 10 pushes the limiting plate 111 to move, the connecting rod 14 is fixed to the limiting plate 111 and is also slidably connected to the connecting column 15. The connecting rod 14 plays a guiding role, restricting the linear movement of the limiting plate 111, preventing the limiting plate 111 from deviating or shaking, and ensuring the stability of the limiting of the reinforcing bar.

[0045] Specifically, a connecting frame 16 is fixed to the bottom of the processing table 1, and a base plate 17 is fixed to the bottom of the connecting frame 16.

[0046] The connecting frame 16 at the bottom of the processing table 1 acts like a sturdy bridge, tightly connecting the processing table 1 to the base plate 17, providing stable support for the entire equipment, effectively dispersing the pressure during operation, and preventing the processing table 1 from shaking.

[0047] Specifically, a push rod 18 is fixed on one side of the connecting frame 16, and a caster wheel 19 is provided at the bottom of the base plate 17.

[0048] When the device needs to be moved, the push rod 18 is pushed to apply force to the connecting frame 16, the connecting frame 16 acts on the base plate 17, and the base plate 17 moves flexibly and smoothly on the road surface by means of the casters 19, so as to realize the convenient transfer of the device.

[0049] During use, the operator smoothly moves the steel bar to be processed into the limiting plate 7 using the guide roller 13. Based on the actual bending requirements, the angle of the bending wheel 5 is adjusted. First, the bending rod 42 is pulled out of the mounting hole 41, and then inserted back into the corresponding mounting hole 41, thereby adjusting the bending wheel 5 to the preset bending angle. After angle adjustment, the steel bar is limited. The bidirectional screw 91 is driven to rotate by rotating the turntable 92. Under the action of the bidirectional screw 91, the two sets of guide plates 10 begin to move towards each other. During the movement of the guide plates 10, they push the limiting plate 111. Since the connecting rod 14 is fixed to the limiting plate 111 and slidably connected to the connecting column 15, the movement of the limiting plate 111 synchronously drives the connecting rod. The connecting rod 14 slides along the connecting column 15, eventually causing the two sets of limiting rings 112 to fit tightly against the surface of the reinforcing bar, effectively preventing the reinforcing bar from shifting during subsequent bending. After the preparation is complete, the reinforcing bar bending operation is carried out. Then, the motor 21 is started, and the guide rod 22 is driven to rotate through the motor 21. The guide rod 22 drives the bending disc 3 and the bending rod 42 to rotate together. During this process, the ball bearing 61 rolls between the connecting shaft 62 and the bending disc 3, which reduces friction and limits the swaying or offset of the connecting shaft 62 relative to the bending disc 3 in the non-rotational direction, ensuring the stability of the entire rotation process. The bending wheel 5 applies force to the reinforcing bar in the limiting disc 7 as the bending rod 42 rotates, realizing the bending of the reinforcing bar.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
