Description

Technical Field

[0001] This invention belongs to the field of bending equipment technology, and particularly relates to a bending equipment for construction engineering. Background Technology

[0002] Construction engineering refers to the production activities during the construction implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. In the construction process, steel bars are used, and bending equipment is needed when bending steel bars to build the framework for concrete pouring, etc.

[0003] Most existing methods of bending steel bars involve manual bending, where positioning screws are welded onto a workbench and then the bars are bent manually. This results in high labor intensity and unsatisfactory bending quality. Some steel bar bending uses equipment, but the automation level of bending and steel bar clamping is low. Bending and steel bar clamping require multiple people to work together, which is not safe or fast enough. Moreover, debris is scattered randomly during the bending process, which is inconvenient to clean up.

[0004] The existing patent (publication number: CN202221474950.4) discloses a steel bar bending device for construction engineering. It features a first motor that drives a first pulley to rotate. The first pulley, via a belt, drives a second pulley to rotate. The second pulley, through a first bevel gear, drives a gear disc to rotate. The gear disc drives a driven gear to rotate, which in turn drives a disc to rotate. The disc's rotation causes a connecting block to move left and right. The connecting block, through an mounting block, drives a pressing block to move left and right, thereby bending the steel bar. This achieves automatic bending, reducing labor intensity. Furthermore, a clamping component and a transmission component are installed on the fixed base. The motor automatically clamps and fixes the steel bar, reducing manual operation, improving bending efficiency and quality. It is safe and practical.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in practical applications, when steel bars need to be bent multiple times, it is inconvenient to adjust the bending surface of the steel bars. Manual adjustment is time-consuming, labor-intensive, and prone to errors, affecting the efficiency and quality of steel bar bending. Therefore, improvements are needed.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-6 This invention provides a technical solution: a bending device for construction engineering, comprising an operating table 1, symmetrical vertical plates 2 slidably disposed on the side of the operating table 1, a movable block 3 fixedly installed between the vertical plates 2, a sleeve rod 4 rotatably disposed in the middle of the movable block 3, a vertical rod 5 fixedly installed on the outer wall of the sleeve rod 4, a symmetrical clamping plate 6 disposed inside the sleeve rod 4, and a symmetrical sliding groove 7 opened on the inner wall of the sleeve rod 4 on the side of the clamping plate 6, a sliding plate 8 slidably disposed on the sliding groove 7, and a fixed plate 8 slidably disposed within the sliding groove 7. A holding spring 9 is fixedly installed between the sleeve rod 4 and the slide plate 8. A hinge column 10 is provided between the slide plate 8 and the clamping plate 6. A symmetrical mounting plate 11 is fixedly installed on one side of the operating table 1. A bending roller 12 is fixedly installed on the top surface of the mounting plate 11. A rotating plate 13 is rotatably arranged between the mounting plates 11. A cylinder 14 is fixedly installed on the top surface of the rotating plate 13. A pressure bar 15 is fixedly installed at the end of the output shaft of the cylinder 14. A driving component 16 is provided at the bottom of the operating table 1.

[0031] When steel bars need to be bent multiple times during construction, the steel bars are first inserted between the clamping plates 6. After insertion, the side walls of the steel bars press against the clamping plates 6, and the clamping plates 6 move towards the inner wall of the sleeve rod 4 under the force. During the movement of the clamping plates 6, the sliding plate 8 is pushed on the sliding groove 7 by the hinge column 10, compressing the holding spring 9. The restoring force of the return spring 19 on the sliding plate 8 and the hinge column 10 presses the clamping plates 6 onto the steel bars to limit the steel bars. Then, the operator pushes the movable block 3, which slides above the operating table 1 through the sliding of the vertical plate 2. The movable block 3 drives the steel bars to move and insert between the insert and the bending roller 12, so that the bending position of the steel bars is aligned with the bending roller 12. At this time, the cylinder 14 is activated, and the output shaft of the cylinder 14 pushes the pressure bar 15 to move and press the pressure bar 15 onto the steel bars. The drive component 16 is activated, and the drive component 16 drives the rotating plate 13 to rotate on the mounting plate 11. The rotation of the rotating plate 13 brings The cylinder 14 and the pressure bar 15 deflect, bending the steel bar during the deflection process. After bending, the steel bar is flipped over for the next bending. The pressure bar 15 is reset, the movable block 3 and the steel bar are moved, and the next bending point of the steel bar is moved to the bending roller 12. The operator rotates the vertical rod 5 on the sleeve rod 4. The vertical rod 5 deflects, causing the sleeve rod 4 to rotate on the movable block 3. During the rotation of the sleeve rod 4, the steel bar is flipped over. When the steel bar is flipped to the designated position, the bending point is aligned with the pressure plate 24. Repeating the above bending operation can perform a second bending. By repeating the above process, the steel bar can be bent multiple times. This bending equipment for construction engineering can facilitate the adjustment of the bending surface of the steel bar during multiple bending without the need for frequent manual adjustment by holding the steel bar, reducing adjustment errors. At the same time, the steel bar has strong stability during bending, which can improve the bending efficiency and bending quality.

[0032] A symmetrical horizontal plate 17 is provided inside the sleeve rod 4. The side of the clamping plate 6 near the inner wall of the sleeve rod 4 is in contact with the side of the horizontal plate 17. The two ends of the hinge column 10 are respectively hinged to the sliding plate 8 and the horizontal plate 17. A symmetrical slide rail 18 is provided on the side of the horizontal plate 17 near the clamping plate 6. A return spring 19 is fixedly installed in the slide rail 18. A symmetrical slide bar 20 is fixedly installed on the side of the clamping plate 6 near the horizontal plate 17. The slide bar 20 is slidably arranged on the slide rail 18. The return spring 19 is pressed between the horizontal plate 17 and the slide bar 20. During the bending process, the reinforcing bar will have a small displacement. When the reinforcing bar is displaced, it drives the clamping plate 6 to slide on the slide rail 18 of the horizontal plate 17 through the slide bar 20, so that the clamping plate 6 slides simultaneously during the small displacement of the reinforcing bar. After the reinforcing bar is bent, the elastic restoring force of the return spring 19 will reset the clamping plate 6, which can effectively reduce the pressure on the clamping plate 6 and protect the hinge column 10.

[0033] An elastic telescopic column 21 is fixedly installed on the inner wall of the vertical plate 2. The end of the elastic telescopic column 21 is fixedly installed on the side of the movable block 3. An electric push rod 22 is fixedly installed on the side of the cylinder 14 on the operating table 1. A bracket 23 is fixedly installed on the end of the output shaft of the electric push rod 22. A pressure plate 24 is fixedly installed on the bracket 23. After the pressure plate 24 holds the steel bar, the electric push rod 22 is activated. The electric push rod 22 pushes the bracket 23 and the pressure plate 24 to move horizontally towards the steel bar, pressing the pressure plate 24 onto the steel bar. This can further improve the stability of the steel bar during bending and improve the bending quality. The elastic telescopic column 21 allows the movable block 3 to move slightly to avoid damage to the clamping plate 6 due to the deflection force of the steel bar when it abuts against the bending roller 12.

[0034] The driving component 16 includes a motor 161 fixedly installed at the bottom of the operating table 1, a drive wheel 162 rotatably installed at the bottom of the operating table 1, a driven wheel 163 rotatably installed on the bottom surface of the mounting plate 11, and a belt 164 sleeved on the drive wheel 162 and the driven wheel 163. The output shaft end of the motor 161 is fixedly installed at the center point of the drive wheel 162. The drive wheel 162, the driven wheel 163 and the belt 164 are meshed and connected for transmission. When the motor 161 at the bottom of the operating table 1 is started, the output shaft of the motor 161 rotates and drives the drive wheel 162 to rotate. The rotation of the drive wheel 162 drives the driven wheel 163 to rotate through the belt 164. The rotation of the driven wheel 163 drives the rotating plate 13 to deflect on the mounting plate 11, which can drive the rotating plate 13 and the pressure strip 15.

[0035] The side of the clamping plate 6 away from the horizontal plate 17 is set as an arc surface, the sliding groove 7 and the sliding plate 8 are both set as arc shapes, the side of the pressure plate 24 away from the bracket 23 is set as an arc surface, and the side of the pressure strip 15 near the bending roller 12 is set as an arc surface; this can improve the stability of pressing and clamping the steel bars and improve the stability during the bending process.

[0036] An annular angle gauge 25 is provided on the side of the movable block 3 near the vertical rod 5, and an indicator block 26 is fixedly installed on the side of the vertical rod 5 near the annular angle gauge 25. When the operator rotates the vertical rod 5, it causes the indicator block 26 to deflect on the annular angle gauge 25. By observing the angle of the annular angle gauge 25 corresponding to the position of the indicator block 26, the bending surface of the steel bar can be precisely adjusted, thereby further improving the bending quality.

[0037] The control panel 1 is equipped with a controller, which is electrically connected to the cylinder 14, the electric push rod 22 and the motor 161 respectively; the controller can automatically control the cylinder 14, the electric push rod 22 and the motor 161 of the device.

[0038] Working principle:

[0039] When steel bars need to be bent multiple times during construction, the steel bars are first inserted between the clamping plates 6. After insertion, the side walls of the steel bars press against the clamping plates 6, and the clamping plates 6 move towards the inner wall of the sleeve rod 4 under the force. During the movement of the clamping plates 6, the sliding plate 8 is pushed on the sliding groove 7 by the hinge column 10, compressing the holding spring 9. The restoring force of the return spring 19 on the sliding plate 8 and the hinge column 10 presses the clamping plates 6 onto the steel bars to limit their movement. Then, the operator pushes the movable block 3, which slides above the operating table 1 through the sliding of the vertical plate 2. The movable block 3 moves the steel bars to be inserted between the insert and the bending roller 12, aligning the bending position of the steel bars. The bending roller 12 is activated, and the electric push rod 22 is started. The electric push rod 22 pushes the bracket 23 and the pressure plate 24 to move horizontally towards the steel bar, pressing the pressure plate 24 onto the steel bar. The cylinder 14 is activated, and the output shaft of the cylinder 14 pushes the pressure bar 15 to move, pressing the pressure bar 15 onto the steel bar. The motor 161 at the bottom of the operating table 1 is activated, and the output shaft of the motor 161 rotates, driving the drive wheel 162 to rotate. The rotation of the drive wheel 162 drives the driven wheel 163 to rotate through the belt 164. The rotation of the driven wheel 163 drives the rotating plate 13 to rotate on the mounting plate 11. The rotation of the rotating plate 13 drives the cylinder 14 and the pressure bar 15 to deflect. During the deflection of the pressure bar 15, the steel bar is bent.

[0040] During the bending process, the steel bar will have a small displacement. When the steel bar is displaced, it will cause the clamping plate 6 to slide on the slide rail 18 of the horizontal plate 17 through the slide bar 20 to compress the return spring 19. This allows the clamping plate 6 to slide simultaneously during the small displacement of the steel bar. After the steel bar is bent, the elastic restoring force of the return spring 19 will reset the clamping plate 6, which can effectively reduce the pressure on the clamping plate 6 and protect the hinge column 10.

[0041] After bending, when flipping the steel bar for the next bending, reset the pressure strip 15 and pressure plate 24, move the movable block 3 and the steel bar, and move the next bending point of the steel bar to the bending roller 12. The operator rotates the vertical rod 5 on the sleeve rod 4. The vertical rod 5 deflects and drives the sleeve rod 4 to rotate on the movable block 3. During the rotation of the sleeve rod 4, the steel bar is flipped. When the steel bar is flipped to the designated position, the bending point is aligned with the pressure plate 24. Repeat the above bending operation to perform a second bending. By repeating the above process, the steel bar can be bent multiple times.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
