Description

Technical Field

[0001] This utility model belongs to the field of steel bar bending processing technology, specifically relating to a steel bar bending device for construction engineering. Background Technology

[0002] A rebar bending machine is a type of bending equipment used on construction sites to bend rebar. It is widely used on construction sites and reduces the workload of workers.

[0003] A search revealed Chinese Patent Publication No. CN212857506U, which discloses a rebar bending device, comprising a vertical plate and a pushing device. The pushing device includes a rotating shaft, a rocker arm with one end perpendicularly connected to the rotating shaft, a slider fixed to the other end of the rocker arm, and a push rod. A connecting block with an arc-shaped groove is fixed to the rear end of the push rod. The rotating shaft is rotatably mounted in the middle of the vertical plate. One end of the vertical plate has a groove and a through hole, with the through hole located at the end of the groove near the rotating shaft. A first guide member for the push rod to move is also fixed on the vertical plate. When the rotating shaft is rotated, the slider slides in the arc-shaped groove and drives the push rod to move along the first guide member, so that the front end of the push rod approaches or moves away from the groove, thereby improving the efficiency of rebar bending and ensuring the bending effect.

[0004] When using the above-mentioned rebar bending device, a single rebar is neatly inserted into the through hole and extended to the bending point. The motor or other electric device is started, or the handle is manually turned to drive the rotating shaft to rotate. After bending the rebar, the rebar is removed and the above operation is repeated for processing other rebars. However, it can only bend single rebars at a time, resulting in low work efficiency. Therefore, it is of great importance to design a rebar bending device for construction engineering to solve the above-mentioned defects. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel bar bending device for construction engineering. This steel bar bending device aims to solve the technical problem that the existing steel bar bending devices cannot bend multiple steel bars at the same time, which affects the work efficiency.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a steel bar bending device for construction engineering. The steel bar bending device includes a machine tool. A threaded adjusting rod is rotatably connected to the top left side of the machine tool. A motor is installed at one end of the threaded adjusting rod and located outside the machine tool. A guide slide rod is fixedly connected to the top right side of the machine tool. A limit plate is slidably connected to the top of the machine tool. A pair of limit frames are fixedly connected to the right side of the machine tool. Each of the two sets of limit frames has a set of arc-shaped limit slide grooves on its corresponding side. A bending frame is hinged between the two sets of limit frames and located on the right side of the machine tool. A motor is installed at the hinge of the bending frame and located outside the limit frame. Five sets of placement slots are opened on the top of both the machine tool and the bending frame.

[0009] When using the rebar bending device of this technical solution, multiple sets of rebars are placed in the placement slot. Motor 1 drives the threaded adjustment rod to rotate, driving the limit frame to move and adjust on the top of the machine tool as needed, limiting and fixing one end of the rebar to adjust the bending length of the rebar. Motor 2 drives the bending frame to rotate, so that the bending frame pushes multiple sets of rebars in the placement slot to bend simultaneously, improving the processing efficiency of the rebars.

[0010] Preferably, the limiting plate has a threaded adjustment hole at the position corresponding to the threaded adjustment rod, and the limiting plate is threadedly connected to the threaded adjustment rod through the threaded adjustment hole.

[0011] Furthermore, the limiting plate has sliding holes at positions corresponding to the guide slide rod, and the limiting plate is slidably connected to the guide slide rod through the sliding holes.

[0012] Furthermore, a set of limiting blocks is fixedly connected to the bottom left side of the limiting plate, at the position corresponding to the placement slot.

[0013] Furthermore, a set of limiting sliders is fixedly connected to both sides of the bending frame and to the positions corresponding to the arc-shaped limiting slide groove. The bending frame is slidably connected to the arc-shaped limiting slide groove through the limiting sliders.

[0014] Furthermore, a steel bar limit strip is fixedly connected to the top of the bending frame and the side corresponding to the machine tool.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The steel bar bending device of this utility model processes multiple sets of steel bars simultaneously through multiple sets of placement slots. The second motor drives the bending frame to rotate, which pushes the steel bars in the placement slots to bend, effectively improving the processing efficiency of steel bars.

[0019] The rebar bending device of this utility model limits and fixes one side of the rebar at the bending point by a rebar limiting strip, preventing the rebar from popping out of the placement groove during the bending process, thereby enhancing the stability and safety of rebar processing.

[0020] The steel bar bending device of this utility model uses a motor to drive the threaded adjustment rod to rotate, so that the limiting plate can be moved and adjusted by being threadedly connected to the threaded adjustment rod through the threaded adjustment hole. The limiting block is used to limit and fix one end of the steel bar, which makes it easy to adjust the bending length of the steel bar according to the needs. Attached Figure Description

[0028] This specific embodiment is a steel bar bending device for building engineering, and its structural schematic diagram is shown below. Figures 1-6 As shown, the rebar bending device includes a machine tool 1, a threaded adjusting rod 101 rotatably connected to the top left side of the machine tool 1, a motor 1011 installed at one end of the threaded adjusting rod 101 and located on the outside of the machine tool 1, and a guide slide rod 102 fixedly connected to the top right side of the machine tool 1.

[0029] First, a limiting plate 103 is slidably connected to the top of the machine tool 1. A threaded adjustment hole 1031 is provided on the limiting plate 103 at the position corresponding to the threaded adjustment rod 101. A sliding hole 1032 is provided on the limiting plate 103 at the position corresponding to the guide slide rod 102. The limiting plate 103 is slidably connected to the guide slide rod 102 through the sliding hole 1032, which improves the stability and smoothness of the movement adjustment of the limiting plate 103. A set of limiting blocks 1033 are fixedly connected to the bottom left side of the limiting plate 103 at the position corresponding to the placement groove 4. The motor 1011 drives the threaded adjustment rod 101 to rotate, so that the limiting plate 103 can be moved and adjusted through the threaded connection between the threaded adjustment hole 1031 and the threaded adjustment rod 101. The limiting blocks 1033 are used to limit and fix one end of the steel bar, which makes it easy to adjust the length of the steel bar bend according to the needs.

[0030] Secondly, a pair of limit frames 2 are fixedly connected to the right side of the machine tool 1, and an arc-shaped limit slide groove 201 is opened on the corresponding side of the two sets of limit frames 2.

[0031] Furthermore, a bending frame 3 is hinged between the two sets of limiting frames 2 and located on the right side of the machine tool 1. A motor 301 is installed at the hinge of the bending frame 3 and on the outside of the limiting frame 2. The motor 301 drives the bending frame 3 to rotate, thereby bending the steel bar. A set of limiting sliders 302 are fixedly connected to both sides of the bending frame 3 and at positions corresponding to the arc-shaped limiting slide groove 201. The bending frame 3 is slidably connected to the arc-shaped limiting slide groove 201 through the limiting sliders 302, which improves the stability of the bending frame 3 in bending the steel bar. A steel bar limiting strip 303 is fixedly connected to the top of the bending frame 3 and on the side corresponding to the machine tool 1. The steel bar limiting strip 303 limits and fixes the bending part of the steel bar on one side, preventing the steel bar from popping out of the placement groove 4 during the bending process, thus enhancing the stability and safety of steel bar processing.

[0032] Finally, the top of both the machine tool 1 and the bending frame 3 is provided with five sets of placement slots 4, which facilitates the simultaneous bending of multiple sets of steel bars. The placement slots 4 are U-shaped structures, and the inner wall of the placement slots 4 is provided with a rubber anti-slip layer 401. The rubber anti-slip layer 401 enhances the anti-slip properties of the steel bars placed in the placement slots 4.

[0033] When using the rebar bending device of this technical solution, the rebar is first placed into the placement groove 4. The rubber anti-slip layer 401 enhances the anti-slip properties of the rebar in the placement groove 4. Motor 1 1011 drives the threaded adjusting rod 101 to rotate, so that the limiting plate 103 moves and is adjusted through the threaded adjustment hole 1031 and the threaded adjusting rod 101. The limiting block 1033 is used to limit and fix one end of the rebar, which facilitates the adjustment of the length of the rebar bending section according to the requirements. The limiting plate 103 is slidably connected to the guide slide rod 102 through the sliding hole 1032, which improves the stability and smoothness of the movement adjustment of the limiting plate 103 and enhances the stability and safety of rebar processing. Motor 2 301 drives the bending frame 3 to rotate, so that it is perpendicular to the machine tool 1. The bending frame 3 is in a vertical angle state, thus bending the steel bar. The bending frame 3 is slidably connected to the arc-shaped limiting groove 201 through the limiting slider 302, which improves the stability of the bending frame 3 in bending the steel bar. The steel bar limiting strip 303 limits and fixes one side of the bending point of the steel bar to prevent the steel bar from popping out of the placement groove 4 during the bending process. After the steel bar is bent, the motor 1011 drives the threaded adjusting rod 101 to rotate, so that the limiting plate 103 moves through the threaded adjusting hole 1031 and the threaded adjusting rod 101 to release the limiting of the steel bar. The motor 2 301 drives the bending frame 3 to rotate and reset, thereby pulling one end of the steel bar out of the placement groove 4 at the top of the machine tool 1, which is convenient for recycling the bent steel bar.

[0034] The entire operation process is simple and convenient. Compared with existing steel bar bending devices, this utility model is designed to facilitate the simultaneous bending of multiple groups of steel bars, thereby improving the efficiency of steel bar processing and enhancing overall practicality.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
