[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] According to the announcement number CN222094578U, the name is a steel bar bending device for construction engineering, including a processing table. Through research and analysis, it was found that although the steel bar bending device has advantages such as easy adjustment of the bending length of the steel bar, easy clamping and fixing of the steel bar, and efficient bending of the steel bar, it also has the following disadvantages to a certain extent.

They require frequent interruptions of the processing flow for manual calibration, making it difficult to balance efficiency and accuracy, thus reducing applicability. In order to solve the above technical problems, it is necessary to design a rebar bending device for construction engineering. Utility Model Content

An extrusion plate 9 is rotatably connected to the bottom of the stud 8. An extrusion roller 16 is rotatably connected to the inner wall of the extrusion plate 9. A placement groove 10 is opened on the surface of the support plate 7. One side of the extrusion plate 9 is connected to the support plate 7. By setting the support plate 7, a stable and sturdy support platform is provided for installing the stud 8 component.

[0021] Please see Figure 1 The stud 8 is threaded to the inner wall of the support plate 7. A handle is welded to the surface of the stud 8. By setting the handle, a stable and comfortable grip is provided to ensure that the user can accurately and powerfully operate the stud 8.

[0022] Please see Figure 1The workbench 1 has a through hole 11 on its surface. One side of the support block 607 penetrates the workbench 1 and is in contact with the inner wall of the through hole 11. The bottom of the workbench 1 is welded with a support leg. By setting the through hole 11, the movement range of the fixed support block 607 is limited, ensuring that the support block 607 operates within a predetermined trajectory. By setting the support leg, a stable support foundation is provided for the workbench 1, ensuring the stability and safety of the workbench 1 structure.

[0023] Please see Figure 2 The shaft of the drive motor 4 passes through the base plate 2 and is fixedly connected to the screw 3. A bearing is provided at the connection between the shaft of the drive motor 4 and the inner wall of the base plate 2. The outer ring of the bearing is fixedly connected to the inner wall of the base plate 2, and the inner ring of the bearing is sleeved on the surface of the shaft of the drive motor 4. By setting the bearing, the shaft of the drive motor 4 is supported, and the friction and wear between the shaft and the inner wall of the base plate 2 during the movement are reduced.

[0024] Please see Figure 1 A fixed frame 12 is welded to the top of the workbench 1. A hydraulic rod 13 is installed through the top of the fixed frame 12.

[0025] In use, first, place the reinforcing bar horizontally in the placement slot 10 on the fixed base 604. Use the measuring ruler 601 to adjust the bending position of the reinforcing bar according to the bending requirements, so that the bending point of the reinforcing bar corresponds to the end of the extrusion rod 5, thereby improving the accuracy of the reinforcing bar bending. Next, rotate the handle to rotate the stud 8, so that the extrusion plate 9 moves under the thrust of the stud 8, so that the extrusion roller 16 contacts the top of the reinforcing bar. Finally, turn on the drive motor 4, so that the screw 3 rotates and drives the moving block 605 to move, so that the extrusion rod 5 moves horizontally under the drive of the moving block 605. The reciprocating motion compresses and bends the reinforcing bar. During bending, the horizontal movement distance of the moving block 605 is measured and observed through the scale line 603. The first electric telescopic rod 606 is activated to extend and retract, causing the extrusion rod 5 supported by the support block 607 to descend away from the top of the workbench 1. The screw 3 causes the moving block 605 to move the first electric telescopic rod 606 and the extrusion rod 5 to the other side. The second electric telescopic rod 609 is activated to push the fixed seat 604 to move laterally along the scale line 603 on the surface. Without the need for manual calibration during the processing, the screw 3 can once again drive the extrusion rod 5 to bend and contact the other side of the reinforcing bar.

[0026] In summary, this steel bar bending device for construction engineering, through the cooperation of workbench 1, base plate 2, screw 3, drive motor 4, extrusion rod 5 and adjustment mechanism 6, solves the problem of frequent interruptions in the processing flow for manual calibration, which makes it difficult to balance efficiency and accuracy.
