Description

Technical Field

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

[0002] Reinforcing steel bars primarily serve a supporting and reinforcing function in building structures. To meet specific structural requirements, such as beam bending and column connections, the steel bars need to be bent into specific shapes. To improve construction efficiency and optimize workflow, the common practice is to pre-treat the steel bars before they leave the factory, precisely bending them according to the design blueprints, and then transporting them directly to the construction site for use. This pre-treatment step significantly reduces on-site processing time and accelerates project progress. Bending equipment is required when bending the steel bars.

[0003] For example, the patent with publication number CN223418213U discloses a rapid bending device for steel bars on construction sites. It uses positioning blocks and bending blocks to press the opposite ends of the steel bars, and uses a telescopic arm to drive the rocker arm to press down and rotate, so that the steel bars bend along the bending groove of the bending disc to achieve the bending effect. It can quickly adjust the shape of the steel bars on the construction site to meet the on-site construction requirements. However, in actual use, it is not possible to accurately adjust the specified bending angle, which increases the difficulty of operation and has certain limitations, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a steel bar bending device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is: A rebar bending device includes: a trolley with movable wheels at its bottom; a positioning plate on the top of the trolley; a positioning rod on the top of the positioning plate; a slide rail fixedly connected to the top of the trolley; a fixing plate slidably connected to the slide rail; an adjusting plate fixedly connected to the top of the fixing plate; a fixing frame rotatably connected to the top of the adjusting plate; a pressure roller rotatably connected to the inner side of the fixing frame; a handle fixedly connected to the side of the fixing frame; a positioning hole on the top of the adjusting plate; and a positioning block threaded into the positioning hole.

[0006] Optionally, the positioning plate has multiple mounting holes that mate with the positioning rod.

[0007] Optionally, the slide rail is a T-shaped slide rail.

[0008] Optionally, the fixing plate has a hole, and a rod is slidably connected inside the hole. A spring is sleeved on the outside of the rod, and both ends of the spring are fixedly connected to the rod and the adjusting plate, respectively. A slot is provided on the top of the slide rail, and one end of the rod is inserted into the slot.

[0009] Optionally, the bottom end of the insertion rod is provided with an arc surface.

[0010] Optionally, the hole, the insertion rod, the spring, and the slot are a set, and multiple sets are provided on the fixing plate.

[0011] Optionally, multiple slide rails are provided.

[0012] Optionally, the adjustment disc is disc-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In use, this application allows manual pushing of the adjustment disc while simultaneously pushing the handle to adjust the placement and angle of the pressure roller. Then, the positioning block is inserted into the designated positioning hole and rotated until its bottom end is pressed against the top of the trolley, locking the adjustment disc in place. This facilitates subsequent bending operations at the designated angle. By installing the positioning block in different positioning holes, the bending angle can be adjusted. Combined with adjusting the position of the adjustment disc, this expands the device's applicability and solves the problem of existing rebar bending devices lacking adequate adjustment capabilities.

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In current technology, the positioning and bending blocks are used to press the opposite ends of the reinforcing bar, and the telescopic arm drives the rocker arm to press down and rotate, so that the reinforcing bar bends along the bending groove of the bending disc to achieve the bending effect. This allows for quick adjustment of the shape of the reinforcing bar on the construction site to meet the on-site construction requirements. However, in actual use, it is impossible to precisely adjust the specified bending angle, which increases the difficulty of operation and has certain limitations, making it inconvenient to use.

[0020] like Figure 1-3 As shown, this utility model embodiment provides a rebar bending device, including: a trolley 10 with movable wheels 11 at its bottom; a positioning plate 20 disposed on the top of the trolley 10; a positioning rod 21 disposed on the top of the positioning plate 20; a slide rail 30 fixedly connected to the top of the trolley 10; a fixing plate 22 slidably connected to the slide rail 30; an adjusting plate 23 fixedly connected to the top of the fixing plate 22; a fixing frame 24 rotatably connected to the top of the adjusting plate 23; a pressure roller 25 rotatably connected to the inner side of the fixing frame 24; a handle 26 fixedly connected to the side of the fixing frame 24; a positioning hole 27 opened on the top of the adjusting plate 23; and a positioning block 28 threadedly connected to the positioning hole 27.

[0021] After moving the trolley 10 to the designated position via its bottom casters 11, manually push the adjusting plate 23 to make it slide the fixing plate 22 on the slide rail 30. At the same time, push the handle 26 to adjust the placement and angle of the pressure roller 25. Then, insert the positioning block 28 into the designated positioning hole 27 and rotate the positioning block 28 so that it goes deep into the positioning hole 27 and its bottom end passes through the positioning hole 27 and abuts against the top of the trolley 10, thus locking the position of the adjusting plate 23. Then, pass the steel bar that needs to be bent through the two positioning rods 21 and the two pressure rollers 25, and push the handle 26. The handle 26 will drive the fixing frame 24 and the pressure roller 25 to rotate on the adjusting plate 23, thereby bending the steel bar. By installing the positioning block 28 in the positioning holes 27 at different positions, the bending angle can be adjusted. In conjunction with adjusting the position of the adjusting plate 23, the applicability of the device can be increased.

[0022] Specifically, the trolley 10 is equipped with a drive motor to adjust the angle of the positioning plate 20, which facilitates the limiting of the steel bars. It can also lock steel bars of different diameters by installing pressure rollers 25 of different sizes and positioning rods 21.

[0023] Furthermore, the positioning disk 20 has multiple mounting holes that cooperate with the positioning rod 21.

[0024] Furthermore, the slide rail 30 is a T-shaped slide rail to prevent the fixing plate 22 from detaching from the slide rail 30.

[0025] Furthermore, the fixing plate 22 has a hole 40, and a rod 41 is slidably connected inside the hole 40. A spring 42 is sleeved on the outside of the rod 41. The two ends of the spring 42 are fixedly connected to the rod 41 and the adjusting plate 23, respectively. A slot 43 is provided on the top of the slide rail 30, and one end of the rod 41 is inserted into the slot 43.

[0026] When the position of the fixing plate 22 is manually adjusted, the spring force of the spring 42 causes one end of the insertion rod 41 to be inserted into the designated slot 43, which helps to lock the position of the fixing plate 22 and improves stability.

[0027] Furthermore, the bottom end of the insertion rod 41 is provided with an arc surface, which does not affect the normal sliding of the fixing plate 22 on the slide rail 30.

[0028] Furthermore, the hole 40, the insertion rod 41, the spring 42 and the slot 43 are a group, and multiple groups are provided on the fixing plate 22, so that multiple insertion rods 41 can work at the same time, which facilitates the limiting of the fixing plate 22.

[0029] Furthermore, multiple slide rails 30 are provided to restrict the fixed plate 22 to slide only laterally and to make the sliding of the fixed plate 22 more stable.

[0030] Furthermore, the adjustment disc 23 is disc-shaped, which makes it easier for staff to determine the insertion position of the positioning block 28.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
