Description

Technical Field

[0001] This utility model relates to the field of bending technology, and in particular to a steel bar bending device. Background Technology

[0002] In mines, various buildings and iron frames are often constructed, requiring the frequent use of steel bars. These bars need to be bent into different shapes to meet various needs. However, current steel bar bending equipment is generally bulky, inconvenient to move, and difficult to transport, making it unsuitable for use in mines. Furthermore, the position of the steel bars is not fixed during the bending process, which can easily lead to positional deviations and inaccurate bending, resulting in unusable bent steel bars and material waste. Therefore, we have developed a steel bar bending tool. Utility Model Content

[0003] This utility model provides a rebar bender to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, this utility model provides a rebar bending tool, comprising a base, a bearing, and a positioning wheel. Two support frames are symmetrically welded to the front end of the base. The bearing is rotatably positioned between the two support frames, with its inner ring welded to both support frames. A positioning cylinder is welded to the top of the outer ring of the bearing, and a handle is welded to one side of the outer ring. Two support seats are symmetrically installed on the end of the base away from the support frames. Two guide rods are symmetrically arranged on each of the two support seats, with a fixing ring at the top of each guide rod. A movable seat is slidably connected to each of the two support seats via the guide rods, and a spring is sleeved in the guide rod between the movable seat and the fixing ring. The positioning wheel is rotatably mounted between the two movable seats.

[0005] Preferably, the handle welded to the outer ring of the bearing forms a 90-degree angle with the positioning cylinder.

[0006] Preferably, a threaded adjusting rod is threadedly connected to the top of the positioning cylinder, and a positioning plate is fixedly provided at the end of the threaded adjusting rod located inside the positioning cylinder, and a driving handle is fixedly provided at the top of the threaded adjusting rod.

[0007] Preferably, the positioning wheel is pressed against the upper surface of the base.

[0008] The beneficial effects of adopting the above technical solutions are:

[0009] One end of the reinforcing bar is held by a positioning wheel, the other end of the reinforcing bar is positioned by a positioning cylinder, and the bearing is driven by the handle to rotate between two support frames, thereby completing the bending of the reinforcing bar. The positioning wheel is set to hold one end of the reinforcing bar to prevent the reinforcing bar from deviating during bending and to improve bending accuracy.

[0010] The threaded adjusting rod in the positioning cylinder, in conjunction with the positioning plate, facilitates the positioning of steel bars of different thicknesses. Furthermore, the spring, in conjunction with the guide rod, allows the movable seat to move, which in turn allows the positioning wheel to move, thus facilitating the positioning of steel bars of different thicknesses and improving applicability.

[0011] This patent has a simple and lightweight structure, making it easy to use in mines. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1-4 In this embodiment, a rebar bending tool includes a base 1, a bearing 2, and a positioning wheel 3. Two support frames 11 are symmetrically welded to the front end of the base 1. The bearing 2 is rotatably disposed between the two support frames 11, and the inner ring of the bearing 2 is welded to the two support frames 11. A positioning cylinder 4 is welded to the top of the outer ring of the bearing 2. A handle 21 is welded to one side of the outer ring of the bearing 2. Two support seats 5 are symmetrically installed on the end of the base 1 away from the support frames 11. Two guide rods 51 are symmetrically provided on the two support seats 5, and a fixing ring 52 is provided at the top of the guide rods 51. A movable seat 53 is slidably connected to the two support seats 5 through the guide rods 51, and a spring 54 is sleeved in the guide rod 51 between the movable seat 53 and the fixing ring 52. The positioning wheel 3 is rotatably installed between the two movable seats 53.

[0021] With the above technical solution, when in use, one end of the reinforcing bar is passed under the positioning wheel 3, so that one end of the reinforcing bar moves through the underside of the bearing 2 and inserts the end of the reinforcing bar into the positioning cylinder 4 welded to the outer ring of the bearing 2. Then, the outer ring of the bearing 2 is driven to rotate by the handle 21, thereby bending the reinforcing bar. Through the setting of the movable seat 53 in conjunction with the guide rod 51 and the spring 54, the movable seat 53 can move up and down in the support seat 5, thereby driving the positioning wheel 3 to move up and down, which is convenient for pressing and positioning reinforcing bars of different thicknesses. This can prevent the reinforcing bars of different thicknesses from deviating when bending, thereby improving the applicability of the equipment. At the same time, the bending equipment has a simple structure and is easy to use in mines.

[0022] Preferably, the handle 21 welded to the outer ring of the bearing 2 forms a 90-degree angle with the positioning cylinder 4.

[0023] With the above technical solution, the handle 21 is at a 90-degree angle to the positioning cylinder 4, which makes it easy for the handle 21 to drive the outer ring of the bearing 4 to rotate the positioning cylinder 4, thereby ensuring the stability when bending force is applied and making it easy to bend the steel bar.

[0024] Preferably, a threaded adjusting rod 41 is threadedly connected to the top of the positioning cylinder 4, and a positioning plate 42 is fixedly provided at the end of the threaded adjusting rod 41 located inside the positioning cylinder 4, and a driving handle 43 is fixedly provided at the top of the threaded adjusting rod 41.

[0025] Through the above technical solution, the drive handle 43 drives the threaded adjusting rod 41 to rotate in the positioning cylinder 4, thereby causing the positioning plate 42 to press and position the end of the reinforcing bar inserted into the positioning cylinder 4, which facilitates the end positioning of reinforcing bars of different thicknesses, thereby improving applicability.

[0026] Preferably, the positioning wheel 3 is pressed against the upper surface of the base 1.

[0027] Through the above technical solution, the positioning wheel 3 initially presses against the upper surface of the base 1, thereby ensuring the pressing force of the positioning wheel 3 and making it easy to stably press against steel bars of different thicknesses.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
