Description

Technical Field

[0001] This utility model relates to the field of steel bar bending technology, 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 actual use, the device can only bend the steel bar once at a time. However, in some special working conditions, the steel bar needs to be bent multiple times. This means that after each bend, the worker needs to disassemble the steel bar and readjust its position for another bend, 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. A bending assembly is provided on the top surface of the bending table. The bending assembly includes a first driving hole opened on the top surface of the bending table near the rear side. A clamping seat is slidably disposed inside the first driving hole. Two clamping plates are provided on the top surface of the clamping seat. A second driving hole is opened at the middle position of the top surface of the bending table. Two support seats are slidably disposed inside the second driving hole. A support roller is rotatably connected to the top surface of the support seats. A third driving hole is opened on the top surface of the bending table near the front side. A driving seat is slidably disposed inside the third driving hole. A sliding seat is slidably disposed on the top surface of the driving seat. A pressure roller is rotatably connected to the top surface of the sliding seat.

[0007] As a further embodiment of this utility model, a first bidirectional lead screw is rotatably connected inside the second drive hole, and both support seats are threadedly connected to the outer wall of the first bidirectional lead screw. A first motor is fixed at the middle position on the left side of the bending table, and the output shaft of the first motor is fixed to the left end of the first bidirectional lead screw. A first lead screw is rotatably connected inside the third drive hole, and the drive seat is threadedly connected to the outer wall of the first lead screw. A second motor is fixed at the left side of the bending table near the front side, and the output shaft of the second motor is fixed to the left end of the first lead screw. An electric push rod is fixed on the bottom surface of the drive seat, and one end of the telescopic rod of the electric push rod is fixed to the bottom surface of the sliding seat.

[0008] As a further embodiment of this utility model, a second lead screw is rotatably connected to the inside of the first drive hole near the right side, a third motor is fixed to the rear side of the bending table near the right side, the output shaft of the third motor is fixed to the rear end of the second lead screw, and the clamping seat is threadedly connected to the outer wall of the second lead screw.

[0009] As a further embodiment of this utility model, a positioning plate is rotatably connected to the front side of the bending table. The positioning plate is made of magnetic material, and the bending table is made of iron alloy material. The positioning plate is magnetically attracted to the front side of the bending table, and a PLC controller is fixed on the left side of the bending table.

[0010] As a further embodiment of this utility model, the top surface of the clamping seat is provided with a sliding groove, and a second bidirectional lead screw is rotatably connected inside the sliding groove. Both clamping plates are threadedly connected to the outer wall of the second bidirectional lead screw. A fourth motor is fixed on the bottom surface of the clamping seat. The output shaft of the fourth motor extends into the interior of the sliding groove. Both the output shaft end of the fourth motor and the outer wall of the second bidirectional lead screw are fixed with bevel gears. The bevel gears of the fourth motor and the bevel gears of the second bidirectional lead screw mesh with each other.

[0011] As a further embodiment of this utility model, a first limiting rod is fixed inside the left side of the first driving hole, and the clamping seat is slidably disposed with the outer wall of the first limiting rod. A second limiting rod is fixed inside the rear side of the third driving hole, and the sliding seat is slidably disposed with the outer wall of the second limiting rod.

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

[0013] By setting a clamping plate to hold the steel bar that needs to be bent, and driving the clamping seat to send the steel bar to the support roller and pressure roller, the support roller fixes the bending point of the steel bar, and then the pressure roller performs the bending operation. After another bend, the pressure roller can be driven to retract into the drive seat and can move freely to both sides of the steel bar. Then, by driving the clamping seat to continue moving the steel bar, other positions on the steel bar can be moved to the pressure roller for further bending operations. This allows for multiple bends of the same steel bar without manual adjustment, meeting different working conditions while increasing bending efficiency. Attached Figure Description

[0022] like Figures 1-4As shown, a steel bar bending device for construction engineering includes a bending table 1. A bending assembly is provided on the top surface of the bending table 1. The bending assembly includes a first driving hole 2 opened on the top surface of the bending table 1 near the rear side. A clamping seat 201 is slidably disposed inside the first driving hole 2. Two clamping plates 202 are provided on the top surface of the clamping seat 201. A second driving hole 203 is opened at the middle position of the top surface of the bending table 1. Two support seats 204 are slidably disposed inside the second driving hole 203. A support roller 205 is rotatably connected to the top surface of the support seats 204. A third driving hole 206 is opened on the top surface of the bending table 1 near the front side. A driving seat 207 is slidably disposed inside the third driving hole 206. A sliding seat 208 is slidably disposed on the top surface of the driving seat 207. A pressure roller 209 is rotatably connected to the top surface of the sliding seat 208.

[0023] like Figures 2-4 As shown, in this embodiment, a first bidirectional lead screw 3 is rotatably connected inside the second drive hole 203. Both support seats 204 are threadedly connected to the outer wall of the first bidirectional lead screw 3. A first motor is fixed at the middle position on the left side of the bending table 1, and the output shaft of the first motor is fixed to the left end of the first bidirectional lead screw 3. A first lead screw 301 is rotatably connected inside the third drive hole 206, and a drive seat 207 is threadedly connected to the outer wall of the first lead screw 301. A second motor is fixed at the left side of the bending table 1 near the front, and the output shaft of the second motor is fixed to the left end of the first lead screw 301. An electric push rod is fixed to the bottom surface of the drive seat 207, and one end of the telescopic rod of the electric push rod is fixed to the bottom surface of the sliding seat 208. The steel bar is clamped and fixed on the clamping seat 201 by the clamping plate 202. Then, the first motor is started to drive the first bidirectional lead screw 3 to rotate. Under the action of the threaded connection, the support seat 204 drives the two support rollers 205 to approach each other and clamp the steel bar. Then, the second motor is started to drive the first lead screw 301 to rotate. Under the action of the threaded connection between the drive seat 207 and the outer wall of the first lead screw 301, the drive seat 207 drives the pressure roller 209 to press against the outer wall of the steel bar, thereby bending the steel bar. After one bend, the clamping seat 201 is driven to move the steel bar, so that other positions on the steel bar can be moved to the pressure roller 209 to continue the bending operation. At the same time, the electric push rod is started to drive the sliding seat 208 to retract into the interior of the drive seat 207, so that the pressure roller 209 avoids the steel bar. At this time, the pressure roller 209 can be driven to move to the left or right side of the steel bar to perform the bending operation according to the bending requirements. This allows for multiple bends of the same steel bar without manual adjustment, meeting different working conditions and increasing bending efficiency.

[0024] like Figures 2-4As shown, in this embodiment, a second lead screw 4 is rotatably connected to the inside of the first drive hole 2 near the right side. A third motor is fixed to the rear side of the bending table 1 near the right side. The output shaft of the third motor is fixed to the rear end of the second lead screw 4. The clamping seat 201 is threadedly connected to the outer wall of the second lead screw 4. By starting the third motor to drive the second lead screw 4 to rotate, under the action of the threaded connection between the clamping seat 201 and the outer wall of the second lead screw 4, the clamping seat 201 drives the bar in the clamp to move, thereby moving the position on the bar that needs to be bent to the support roller 205 and the pressure roller 209 for bending operation.

[0025] like Figures 2-4 As shown, in this embodiment, a positioning plate 401 is rotatably connected to the front side of the bending table 1. The positioning plate 401 is made of magnet material, and the bending table 1 is made of iron alloy material. The positioning plate 401 is magnetically attracted to the front side of the bending table 1. A PLC controller is fixed on the left side of the bending table 1. The first motor, the second motor, the third motor, and the electric push rod are all electrically connected to the PLC controller. By setting the positioning plate 401, when the driving clamping seat 201 moves the clamped steel bar, the end of the steel bar abuts against the positioning plate 401 to position the steel bar. Then, the positioning plate 401 can be rotated downward to avoid the end of the steel bar. At this time, the PLC controller starts the third motor and controls the stroke of the steel bar so that the bending point of the steel bar moves precisely to the support roller 205 and the pressure roller 209, and the bending operation can begin.

[0026] like Figures 2-4 As shown in this embodiment, the top surface of the clamping seat 201 is provided with a sliding groove 5. A second bidirectional lead screw 501 is rotatably connected inside the sliding groove 5. Both clamping plates 202 are threadedly connected to the outer wall of the second bidirectional lead screw 501. A fourth motor is fixed on the bottom surface of the clamping seat 201. The fourth motor is electrically connected to the PLC controller. The output shaft of the fourth motor extends into the interior of the sliding groove 5. Both the output shaft end of the fourth motor and the outer wall of the second bidirectional lead screw 501 are fixed with bevel gears. The bevel gears of the fourth motor and the bevel gears of the second bidirectional lead screw 501 mesh with each other. By starting the fourth motor, the second bidirectional lead screw 501 is driven to rotate under the meshing action of the bevel gears of the fourth motor and the second bidirectional lead screw 501. Under the action of the two clamping plates 202 being threadedly connected to the outer wall of the second bidirectional lead screw 501, the two clamping plates 202 move closer to each other and clamp and fix the reinforcing bar.

[0027] like Figures 2-4As shown, in this embodiment, a first limiting rod 6 is fixed inside the left side of the first driving hole 2, and the clamping seat 201 is slidably disposed with the outer wall of the first limiting rod 6. A second limiting rod 601 is fixed inside the rear side of the third driving hole 206, and the sliding seat 208 is slidably disposed with the outer wall of the second limiting rod 601. The first limiting rod 6 can limit and support the movement of the clamping seat 201, and the second limiting rod 601 can limit and support the sliding seat 208.

[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, by placing the steel bar to be bent on the top surface of the bending table 1, and then starting the fourth motor, the bevel gear of the fourth motor meshes with the bevel gear of the second bidirectional lead screw 501, thereby driving the second bidirectional lead screw 501 to rotate. With the two clamping plates 202 threadedly connected to the outer wall of the second bidirectional lead screw 501, the two clamping plates 202 move closer to each other and clamp and fix the steel bar. At this time, the third motor is started to drive the second lead screw 4 to rotate. With the clamping seat 201 threadedly connected to the outer wall of the second lead screw 4, the clamping seat 201 drives the clamped steel bar to move, so that the end of the steel bar abuts against the positioning plate 401. Then, the positioning plate 401 can be rotated downward to avoid the end of the steel bar, and the bending operation can begin. At this time, the PLC controller starts the third motor and controls the stroke of the steel bar, so that the bending point of the steel bar moves precisely to the support roller 205 and the pressure roller 209. At this time, the first motor is started to drive the first bidirectional lead screw 3 to rotate. Under the action of the threaded connection between the support seat 204 and the outer wall of the first bidirectional lead screw 3, the support seat 204 drives the two support rollers 205 to approach each other and clamp the steel bar. Then, the second motor is started to drive the first lead screw 301 to rotate. Under the action of the threaded connection between the drive seat 207 and the outer wall of the first lead screw 301, the drive seat 207 drives the pressure roller 209 to press against the outer wall of the steel bar, thereby bending the steel bar. After one bend, the clamping seat 201 is driven to move the steel bar, so that other positions on the steel bar can be moved to the pressure roller 209 to continue the bending operation. At the same time, the electric push rod is started to drive the sliding seat 208 to retract into the interior of the drive seat 207, so that the pressure roller 209 avoids the steel bar. At this time, the pressure roller 209 can be driven to move to the left or right side of the steel bar to perform the bending operation according to the bending requirements. This allows for multiple bends of the same steel bar without manual adjustment, meeting different working conditions and increasing bending efficiency.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
