[0018] Example 1
[0019] like Figures 1 to 4 As shown, the present invention proposes a rebar straightening device, including a processing table 1 and a movable frame 2; a clamping component 102 is provided on one side of the top of the processing table 1, and a horizontal moving mechanism 101 is provided on the other side. The clamping component 102 is the prior art and is used to clamp and limit the rebar; the movable frame 2 is installed on the horizontal moving mechanism 101, and the movable frame 2 is driven by the horizontal moving mechanism 101 to slide and adjust horizontally along the processing table 1. Multiple sets of first straightening units are evenly arranged on the inner wall of the movable frame 2.
[0020] The first straightening unit includes a first hydraulic cylinder 3, a second hydraulic cylinder 4, and a straightening mechanism; the first hydraulic cylinder 3 is vertically installed at the bottom inside the movable frame 2; the second hydraulic cylinder 4 is vertically installed at the top inside the movable frame 2; the straightening mechanism is provided in two sets, which are symmetrically installed on the first hydraulic cylinder 3 and the second hydraulic cylinder 4. The straightening mechanism consists of a mounting frame installed on the first hydraulic cylinder 3 or the second hydraulic cylinder 4 and a straightening wheel that rotates and connects to the mounting frame. The straightening wheel is provided with a straightening groove 605, and the two sets of straightening grooves 605 on the upper and lower sets of straightening wheels are respectively rolledly connected to the upper and lower ends of the outer wall of the steel bar.
[0021] Furthermore, the inner wall of the movable frame 2 is also provided with multiple sets of second correction units. The second correction unit has the same structure as the first correction unit. The first hydraulic cylinder 3 and the second hydraulic cylinder 4 in the second correction unit are horizontally installed on the inner side walls of the movable frame 2 to straighten the left and right ends of the outer wall of the steel bar, thereby improving the straightening efficiency of the steel bar.
[0022] In this embodiment, the horizontal moving mechanism 101 is activated to move the moving frame 2 to a position close to the clamping assembly 102, clamping one end of the rebar through the clamping assembly 102. The controller activates the first hydraulic cylinder 3 and the second hydraulic cylinder 4 to adjust the rebar, so that the portion of the rebar near the clamping assembly 102 is clamped between the two sets of straightening wheels in the upper and lower straightening mechanisms. It should be noted that the clamping assembly 102 is equipped with an infrared transmitter, and the straightening mechanism is equipped with an infrared receiver. Adjustment allows the rebar to be straightened while remaining parallel to the processing table 1. The water flow is then restarted. The translation mechanism 101 drives the moving frame 2 to move horizontally along the processing table 1, gradually moving away from the clamping assembly 102. By rolling along the outer wall of the steel bar with two sets of straightening wheels, the steel bar can be straightened, reducing friction on the outer wall of the steel bar and reducing secondary damage. By adjusting the angle at which the steel bar is clamped by the clamping assembly 102, the bent sections of the steel bar in other directions can be straightened. With the setting of multiple sets of first and second straightening units, the outer wall of the steel bar can be corrected in different directions at the same time, without having to adjust the clamping angle of the clamping assembly 102 on the steel bar many times, further improving the straightening efficiency.
[0023] Example 2
[0024] like Figures 2 to 4 As shown, the present invention proposes a rebar straightening device. Compared with Embodiment 1, the mounting frame consists of a mounting plate 5 and an adjusting plate 7 that is adjustablely connected to the mounting plate 5. The mounting plate 5 is L-shaped and is connected to the first hydraulic cylinder 3 or the second hydraulic cylinder 4.
[0025] Furthermore, a guide rod 701 is installed at the top of the adjusting plate 7. The guide rod 701 is slidably connected to the inner cavity of the mounting plate 5. A screw 702 is rotatably connected to the mounting plate 5. The screw 702 is threadedly connected to the adjusting plate 7.
[0026] Furthermore, the straightening wheel is composed of a first abutment plate 6 of the rotating connecting mounting plate 5, a second abutment plate 703 of the rotating connecting adjusting plate 7, and a replacement plate 603 detachably installed between the first abutment plate 6 and the second abutment plate 703. The straightening groove 605 is provided on the outer wall of the replacement plate 603. The replacement plate 603 is provided in multiple sets, and the corresponding straightening grooves 605 on the multiple sets of replacement plates 603 are provided with different sizes to adapt to the straightening of steel bars of different specifications.
[0027] Furthermore, a pin 601 is installed on the first abutment plate 6 at the center of the end away from the mounting plate 5. The pin 601 is slidably inserted into the center of the replacement plate 603. Multiple sets of first rods 602 are evenly installed around the pin 601 on the first abutment plate 6. Multiple sets of second rods 704 are evenly installed on the second abutment plate 703 at the end away from the adjusting plate 7. Multiple sets of slots 604 are provided at both ends of the replacement plate 603. The first rods 602 and the second rods 704 are respectively inserted into the corresponding slots 604.
[0028] In this embodiment, rotating the screw 702, guided by the guide rod 701, causes the adjusting plate 7 to move away from the mounting plate 5 until the second insert 704 on the second abutment plate 703 moves away from the slot 604 at one end of the replacement plate 603. At this time, the replacement plate 603 is slid away along the insert post 601 until the replacement plate 603 separates from the first abutment plate 6 and the insert post 601, and the replacement plate 603 can be removed. Then, the replacement plate 603 with the appropriate size straightening groove 605 is slid into the insert post 601 until the slot 604 at the other end of the replacement plate 603 is inserted into the first insert rod 602, and the replacement plate 603 abuts against the first abutment plate 6. Then, the screw 702 is reversed, causing the adjusting plate 7 to move the second abutment plate 703 closer to the replacement plate 603 until it is pressed tightly, thus completing the installation of the new replacement plate 603. This method is convenient for straightening steel bars of different sizes, and the replacement is quick and easy, with a wide range of applications.
[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
