[0016] The present invention will be further described below with reference to the accompanying drawings: Example

[0017] See attached document Figure 1-3 A steel bar bending device for construction includes a fixed frame 1, a support column 2, a rotating plate 3, and an adjustment component. The support column 2 is fixedly installed at the bottom center of the fixed frame 1, and the end of the support column 2 is rotatably connected to the rotating plate. An adjustment component is installed below the rotating plate 3, and the upper part of the outer wall of the rotating plate 3 is rotatably connected to the fixed frame 1.

The first hydraulic cylinder 403 drives the connecting seat 404 to move downwards, which in turn drives the connecting rod 410 to rotate. The connecting rod 410 drives the slider 405 to move along the outer wall of the sliding rod 406 towards the center of the rotating disk 3. The slider 405 drives the connecting block 407 to move. The connecting blocks 407 on both sides move synchronously in opposite directions. The connecting blocks 407 drive the second hydraulic cylinder 409 and the bending column 408 to move. The upper end of the sleeve 401 is fixedly connected to the rotating disk 3, and the inner wall of the sleeve 401 is rotatably connected to the support column 2. The lower end of the sleeve 401... The sleeve 401 is fixedly connected to the circular plate 402, and its outer wall is slidably connected to the connecting seat 404.

The inner wall of the slider 405 is slidably connected to the slide rod 406. A second hydraulic cylinder 409 is fixedly installed at the lower end of the connecting block 407. The output end of the second hydraulic cylinder 409 is fixedly connected to the bending column 408. The outer wall of the bending column 408 is slidably connected to the connecting block 407. The extension and retraction of the corresponding bending column 408 can be adjusted by the second hydraulic cylinder 409. Figure 1 and Figure 2 As shown, when the left bending column 408 is retracted into the connecting block 407, the drive component 5 drives the rotating disk 3 to rotate counterclockwise, and the right bending column 408 bends the steel bar. Similarly, when the right bending column 408 is retracted into the connecting block 407, the drive component 5 drives the rotating disk 3 to rotate clockwise, and the left bending column 408 bends the steel bar. This satisfies the need to bend the steel bar in different directions, thus ensuring that the steel bar does not need to be reversed when continuously bending it.

A drive assembly 5 is installed below the outer wall of the rotating disk 3. The fixed end of the drive assembly 5 is located on the side of the fixed frame 1 adjacent to the rotating disk 3. Two sets of fixed blocks 201 are installed on the upper side of the support column 2, and the fixed blocks 201 on both sides are symmetrically mirrored. Multiple teeth are distributed in annular array below the outer wall of the rotating disk 3. The drive assembly 5 is powered by a motor, and the output end of the motor is equipped with a gear that meshes with the rotating disk 3 to drive the rotating disk 3 to rotate.

Guide rods 603 are respectively provided on both sides of the connecting plate 602. The outer wall of the guide rod 603 is slidably connected to the fixing frame 1. The middle part of the connecting plate 602 is fixedly connected to the clamping block 604 on one side, and the end of the clamping block 604 on the other side is fixedly connected to the fixing frame 1. The side clamping blocks 604 are arranged symmetrically and mirror-like. The two clamping blocks 604 on both sides correspond to the two fixing blocks 201 on both sides. The output end of the third hydraulic cylinder 601 moves downward. The third hydraulic cylinder 601 drives the connecting plate 602 to move downward. The connecting plate 602 drives the guide rods 603 on both sides to slide along the fixing frame 1. The connecting plate 602 drives the clamping block 604 on the corresponding side to move downward. The distance between the clamping blocks 604 on both sides is shortened, thereby fixing the steel bar. When the steel bar is placed on the clamping block 604 on one side of the fixing frame 1, the steel bar can be inserted into the distance between the two fixing blocks 201.

[0023] Specifically, when the reinforcing bar needs to be bent a short distance, the first hydraulic cylinder 403 drives the connecting seat 404 to move downwards. The connecting seat 404 drives the connecting rod 410 to rotate. The connecting rod 410 drives the slider 405 to move along the outer wall of the sliding rod 406 towards the center of the rotating disk 3. The slider 405 drives the connecting block 407 to move. The connecting blocks 407 on both sides move synchronously and in opposite directions. The connecting block 407 drives the second hydraulic cylinder 409 to move and the bending column 408 to move. After adjusting to the appropriate position, the first hydraulic cylinder 403 is controlled to stop moving, thereby adjusting the distance between the position of the bending column 408 on both sides and the center of the rotating disk 3. According to the direction of bending the reinforcing bar, the bending column 408 on the corresponding side is retracted. Then, the reinforcing bar is placed between the fixing blocks 201 on both sides through the fixing component 6. Then, the fixing component 6 is controlled to fix the reinforcing bar. According to the direction of bending the reinforcing bar, the drive component 5 is controlled to rotate, thereby driving the bending column 408 to move circumferentially through the rotating disk 3, thereby achieving the bending of the reinforcing bar.
