Description

Technical Field

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

[0002] Reinforcing bars are long, thin steel bars, including plain round bars, ribbed bars, and twisted bars. They are also one of the main building materials in construction projects, primarily bearing the tensile stress of concrete. In current building construction, reinforcing bars often need to be bent to ensure the stability of connections in areas such as building corners.

[0003] An existing steel bar bending device for construction engineering (publication number: CN222094578U) has at least the following drawbacks: In construction engineering, steel bars with bent ends are often needed to make cast-in-place frames. However, this device cannot bend both ends of the steel bars simultaneously in actual use, which affects the construction efficiency of construction engineering. In addition, the device does not have an alignment mechanism, which means that when bending multiple steel bars of the same type, it is necessary to manually align and arrange the steel bars side by side, which affects the bending efficiency. Therefore, this utility model is proposed. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel bar bending device for construction engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel bar bending device for construction engineering includes a bending table. The top surface of the bending table is provided with a bending assembly for bending steel bars. The bending assembly includes two bending seats that are slidably disposed on the top surface of the bending table near the left and right sides. A rotating table is provided on the top surface of the bending seats. Bending rollers are rotatably connected to the center and edge of the top surface of the rotating table. An alignment plate is also fixed on the top surface of the rotating table near the edge. Two clamping blocks are slidably disposed at the center of the top surface of the bending table.

[0007] As a further embodiment of this utility model, a bidirectional lead screw is rotatably connected to the center of the top surface of the bending table, and the clamping block is threadedly connected to the outer wall of the bidirectional lead screw. A first motor is fixed to the front side of the bending table, and the output shaft of the first motor is fixed to the front end of the bidirectional lead screw. A first lead screw is rotatably connected to the top surface of the bending table near the left and right sides, and the bending seat is threadedly connected to the outer wall of the first lead screw. A second motor is fixed to both the left and right sides of the bending table, and the output shaft of the second motor is fixed to one end of the first lead screw. A third motor is fixed to the inner bottom surface of the bending seat, and the output shaft of the third motor is fixed to the bottom surface of the rotating table.

[0008] As a further embodiment of this utility model, connecting seats are fixed on both sides of the two bending seats that are close to each other. A screw is rotatably connected inside the connecting seat, and an abutment plate is threadedly connected to the outer wall of the screw.

[0009] As a further embodiment of this utility model, the top surface of the bending table is provided with scale lines near the left and right sides, and a finger block is fixed on the front side of the bending seat, with the end of the finger block pointing to the scale line.

[0010] As a further embodiment of this utility model, two first limiting rods are fixed on the top surface of the bending table near the left and right sides, and the bending seat is slidably disposed with the outer wall of the first limiting rods. Two second limiting rods are fixed at the middle position of the top surface of the bending table, and the clamping block is slidably disposed with the outer wall of the second limiting rods.

[0011] As a further embodiment of this utility model, a number of directional support wheels are fixed on the inner bottom surface of the bending seat, and the rollers of the directional support wheels abut against the bottom surface of the rotating table.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting clamping blocks to hold the middle of several steel bars that need to be bent, the alignment plate is then rotated to the end of the steel bars and abuts against the end of the steel bars to align the multiple steel bars. Then, the bending roller is rotated to the position of the steel bar, and the abutting plate abuts against the outer wall of the steel bar. Then, the bending seat is driven to move the bending roller precisely to the bending position on the steel bar according to the scale line, and then the bending operation is performed. This allows for bending operations on both ends of the steel bar at the same time, and multiple steel bars of the same type can be bent at one time. The bending position is accurate, the bending speed is fast, and the work efficiency is increased. Attached Figure Description

[0022] like Figures 1-4 As shown, a steel bar bending device for construction engineering includes a bending table 1. The top surface of the bending table 1 is provided with a bending assembly for bending steel bars. The bending assembly includes two bending seats 2 that are slidably disposed on the top surface of the bending table 1 near the left and right sides. The top surface of the bending seats 2 is provided with a rotating table 201. Bending rollers 202 are rotatably connected to the center and edge of the top surface of the rotating table 201. An alignment plate 203 is also fixed near the edge of the top surface of the rotating table 201. Two clamping blocks 204 are slidably disposed at the center of the top surface of the bending table 1.

[0023] like Figures 2-4As shown, in this embodiment, a bidirectional lead screw 205 is rotatably connected to the center of the top surface of the bending table 1. A clamping block 204 is threadedly connected to the outer wall of the bidirectional lead screw 205. A first motor is fixed to the front side of the bending table 1, and the output shaft of the first motor is fixed to the front end of the bidirectional lead screw 205. A first lead screw 206 is rotatably connected to the top surface of the bending table 1 near the left and right sides. A bending seat 2 is threadedly connected to the outer wall of the first lead screw 206. Second motors are fixed to both the left and right sides of the bending table 1, and the output shafts of the second motors are fixed to one end of the first lead screw 206. A third motor is fixed to the inner bottom surface of the bending seat 2, and the output shaft of the third motor is fixed to the bottom surface of the rotating table 201. By placing several steel bars side-by-side between two clamping blocks 204, and then driving the first motor to rotate the bidirectional lead screw 205, the two clamping blocks 204 move closer together and slightly clamp the several steel bars arranged side-by-side. Then, the bending table is started... The third motor drives the rotary table 201 to rotate, causing the alignment plate 203 on the rotary table 201 to rotate to the position corresponding to the end of the rebar. Then, the second motor drives the first lead screw 206 to rotate. Under the action of the threaded connection between the bending seat 2 and the outer wall of the first lead screw 206, the bending seat 2 drives the alignment plate 203 to abut against the end of the rebar. With both alignment plates 203 abutting against the end of the rebar at the same time, several rebars are aligned and arranged. Then, the alignment plate 203 is driven away from the rebar, and the first motor is started to drive the clamping block 204 to tightly clamp the rebar. At this time, the third motor is started to drive the rotary table 201, so that the gap between the two bending rollers 202 corresponds to the end of the rebar. Then, the second motor is started to drive the bending seat 2 to move to the bending position on the rebar. When the two bending rollers 202 move to the bending position of the rebar, the third motor is started to drive the rotary table 201 to rotate, so that the bending rollers 202 bend the rebar. Then, the clamping block 204 can be released and the bent rebar can be removed.

[0024] like Figures 2-4 As shown in this embodiment, connecting seats 3 are fixed on both sides of the two bending seats 2 that are close to each other. A screw 301 is rotatably connected inside the connecting seat 3. An abutment plate 302 is threadedly connected to the outer wall of the screw 301. By rotating the screw 301, the abutment plate 302 is driven to abut against the opposite side of the steel bar bend, thereby supporting and limiting the steel bar and preventing other parts of the steel bar from bending under the action of the end bending force.

[0025] like Figures 2-4 As shown in this embodiment, the top surface of the bending table 1 is provided with scale lines 4 near the left and right sides. The front side of the bending seat 2 is fixed with a finger block 401, and the end of the finger block 401 points to the scale line 4. By setting the scale line 4, it is convenient for the staff to accurately position the bending roller 202 to the bending position of the steel bar, thereby increasing the bending accuracy.

[0026] like Figures 2-4 As shown in this embodiment, two first limiting rods 5 are fixed on the top surface of the bending table 1 near the left and right sides. The bending seat 2 is slidably disposed with the outer wall of the first limiting rods 5. Two second limiting rods 501 are fixed at the middle position of the top surface of the bending table 1. The clamping block 204 is slidably disposed with the outer wall of the second limiting rods 501. The first limiting rods 5 and the second limiting rods 501 can activate the limiting effect on the bending seat 2 and the clamping block 204, making the movement of the bending seat 2 and the clamping block 204 more stable.

[0027] like Figures 2-4 As shown in this embodiment, a number of directional support wheels 6 are fixed on the inner bottom surface of the bending seat 2. The rollers of the directional support wheels 6 abut against the bottom surface of the rotary table 201. By setting the directional support wheels 6, the rotary table 201 can play an auxiliary support role, making the rotation of the rotary table 201 more stable.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, when bending the reinforcing bars, several reinforcing bars are placed side by side between two clamping blocks 204. Then, the first motor is driven to rotate the bidirectional lead screw 205. Under the action of the threaded connection between the clamping blocks 204 and the outer wall of the bidirectional lead screw 205, the two clamping blocks 204 move closer to each other and slightly clamp the several reinforcing bars arranged side by side. Then, the third motor is started to rotate the rotating table 201, so that the alignment plate 203 on the rotating table 201 rotates to the position corresponding to the end of the reinforcing bar. Then, the second motor is driven to rotate the first lead screw 206. Under the action of the threaded connection between the bending seat 2 and the outer wall of the first lead screw 206, the bending seat 2 drives the alignment plate 203 to abut against the end of the reinforcing bar. Two alignment plates 203 simultaneously abut against the ends of the reinforcing bars, aligning several reinforcing bars. Then, the alignment plates 203 are driven away from the reinforcing bars, and the first motor is started to drive the clamping block 204 to tightly clamp the reinforcing bars. At this time, the rotating screw 301 drives the abutment plate 302 to abut against the outer wall of the reinforcing bar. Then, the third motor is started to drive the rotating table 201, so that the gap between the two bending rollers 202 corresponds to the end of the reinforcing bar. Then, the second motor is started to drive the bending seat 2 to move to the bending position on the reinforcing bar. During this process, the adjustment is based on the position of the index block 401 on the scale line 4. When the two bending rollers 202 move to the bending position of the reinforcing bar, the third motor is started to drive the rotating table 201 to rotate, so that the bending rollers 202 bend the reinforcing bar. Then, the clamping block 204 can be released and the bent reinforcing bar can be removed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
