Technical Field

[0001] This utility model relates to the field of bending device technology, specifically to a bending device for alloy bars. Background Technology

[0002] During processing, bar stock needs to be bent. However, current bending devices have the following problems: they can generally only bend once and cannot bend the bar stock again, resulting in a limited range of bending methods. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A bending device for alloy bars includes a worktable with a support wheel rotatably connected to it. A first hydraulic cylinder and a second hydraulic cylinder are mounted on the right side of the support wheel on the worktable, parallel to each other, with the second hydraulic cylinder positioned above the first. The telescopic end of the first hydraulic cylinder is connected to a first U-shaped seat, and a first pressure roller is rotatably connected inside the first U-shaped seat, aligned with the support wheel. The telescopic end of the second hydraulic cylinder is connected to a second U-shaped seat, and a second pressure roller is rotatably connected inside the second U-shaped seat. A third hydraulic cylinder is located on the worktable below and to the left of the support wheel, perpendicular to the line where the first hydraulic cylinder is located. The telescopic end of the third hydraulic cylinder is connected to a third U-shaped seat, and a third pressure roller is rotatably connected inside the third U-shaped seat.

[0006] Preferably, a fourth hydraulic cylinder is installed on the workbench below the support wheel, and a stop block is connected to the telescopic end of the fourth hydraulic cylinder, with the straight line containing the right tangent edge of the support wheel located at the center of the stop block.

[0007] Preferably, a touch screen is provided on one side of the workbench.

[0008] Preferably, the workbench is equipped with a controller, and the touch display, the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder are all electrically connected to the controller.

[0009] Preferably, the workbench is provided with a plurality of screw holes, and the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder and the fourth hydraulic cylinder are all installed on the workbench by screws and screw holes.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] One side of the bar is pressed against the support roller. Then, the first hydraulic cylinder is extended to press the bar tightly against the support roller. The second hydraulic cylinder is then extended to squeeze the bar, causing it to bend along the support roller for the first time until it forms an L-shape. At this point, the third pressure roller is still pressed against the side of the bar away from the support roller. The third hydraulic cylinder is then extended to squeeze the bar, causing it to bend along the second pressure roller for the second time, thus bending the bar into a Z-shape.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1

[0017] Please see Figure 1 A bending device for alloy bars includes a worktable 1, on which a support wheel 2 is rotatably connected. A first hydraulic cylinder 3 and a second hydraulic cylinder 4 are mounted on the right side of the support wheel on the worktable 1. The first hydraulic cylinder 3 and the second hydraulic cylinder 4 are parallel, and the second hydraulic cylinder 4 is located above the first hydraulic cylinder 3. The telescopic end of the first hydraulic cylinder 3 is connected to a first U-shaped seat 5. A first pressure roller 6 is rotatably connected inside the first U-shaped seat 5 and is aligned with the support wheel 2. The telescopic end of the second hydraulic cylinder 4 is connected to a second U-shaped seat 7. A second pressure roller 8 is rotatably connected inside the second U-shaped seat 7. A third hydraulic cylinder 9 is located on the worktable 1 below the left side of the support wheel. The third hydraulic cylinder 9 is perpendicular to the line where the first hydraulic cylinder 3 is located. The telescopic end of the third hydraulic cylinder 9 is connected to a third U-shaped seat 10. A third pressure roller 11 is rotatably connected inside the third U-shaped seat 10.

[0018] A fourth hydraulic cylinder 12 is installed on the workbench 1 below the support wheel. The telescopic end of the fourth hydraulic cylinder 12 is connected to a stop block 13, and the straight line containing the right tangent edge of the support wheel 2 is located at the center of the stop block 13. When placing the bar, the fourth hydraulic cylinder 12 can be controlled to move the stop block 13 to the desired position. Then, one end of the bar is placed against the stop block 13, providing a support point for the end face of the bar and preventing it from moving downwards when bending.

[0019] A touch screen display 14 is provided on one side of the workbench 1. A controller is installed inside the workbench 1, and the touch screen display 14, the first hydraulic cylinder 3, the second hydraulic cylinder 4, the third hydraulic cylinder 9, and the fourth hydraulic cylinder 12 are all electrically connected to the controller. The touch screen display has touch buttons for controlling the operation of the first, second, third, and fourth hydraulic cylinders. The controller contains a control program to facilitate the orderly operation of the aforementioned components.

[0020] The working principle of this embodiment is as follows:

[0021] like Figure 2 As shown, one side of the bar is placed against the support roller. Then, the first hydraulic cylinder is extended to press the bar tightly against the support roller. The second hydraulic cylinder is then extended to squeeze the bar, causing it to bend along the support roller for the first time until it forms an L-shape. At this point, the third pressure roller is still against the side of the bar away from the support roller. The third hydraulic cylinder is then extended to squeeze the bar, causing it to bend along the second pressure roller for the second time, thus bending the bar into a Z-shape.

[0023] Based on Embodiment 1, the workbench 1 is provided with several screw holes 15. The first hydraulic cylinder 3, the second hydraulic cylinder 4, the third hydraulic cylinder 9, and the fourth hydraulic cylinder 12 are all installed on the workbench 1 by screws and screw holes, so as to facilitate the adjustment of the positions of the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, and the fourth hydraulic cylinder according to the bending requirements of the bar.
