[0002] With the rapid development of aluminum alloy technology, aluminum alloys are being used more and more widely, which has also put forward higher requirements for the processing of aluminum alloys. For example, in the bending process of aluminum alloy sheets, traditionally, manual bending is carried out using tools such as wrenches and bench vises.

[0003] A bending machine is a common metal processing equipment, mainly used to bend metal sheets into the required shape. Before bending metal materials, it is necessary to use limiting components to limit the metal sheets to prevent them from shifting during bending and causing deviations in the bending of the metal sheets.

[0004] Existing bending machine limit devices are inconvenient for adjusting the bending position of sheet metal during use, have poor equipment versatility, and cannot adapt to sheet metal with certain protrusions on the surface, thus failing to guarantee the stability of the fixed position.

[0005] Therefore, it is necessary to invent an adjustable limiting device for bending and forming metal sheets to solve the above problems. Utility Model Content

[0024] The fixing mechanism 7 includes a fixing frame 71, the top of the fixing frame 71 is fixedly connected to the bottom of the fixing plate 6, a sliding block 72 is slidably connected to the inner wall of the fixing frame 71, a spring 73 is fixedly connected between the top of the sliding block 72 and the top of the inner wall of the fixing frame 71, a connecting block 74 is fixedly connected to the bottom of the sliding block 72, the bottom of the connecting block 74 passes through the fixing frame 71 and extends to the outside of the fixing frame 71, and a fixing plate 75 is fixedly connected to the bottom of the connecting block 74.

[0025] A threaded block 8 is connected through the top of the connecting frame 5. A threaded post 9 is connected inside the threaded block 8. The bottom end of the threaded post 9 is rotatably connected to the top of the fixing plate 6. A rotating disk 10 is fixedly connected to the top of the threaded post 9.

[0026] The rotating disk 10 drives the threaded column 9 to rotate, and the threaded column 9, through the action of the threaded block 8, drives the fixed plate 6 to move.

[0027] Multiple telescopic rods 11 are fixedly connected between the top of the fixed plate 6 and the top of the inner wall of the connecting frame 5. The telescopic rods 11 are used to improve the stability of the fixed plate 6. A support plate 12 is fixedly connected to the top of one side of the side plate 4. An electric push cylinder 13 is fixedly connected between the bottom of the support plate 12 and the top of the connecting frame 5.

[0028] The electric push cylinder 13 adopts existing technology. The electric push cylinder 13 drives the connecting frame 5 to move, so that the height of the connecting frame 5 is adapted to the lower mold of the bending machine.

[0029] The drive assembly 3 includes a drive motor 31. One side of the drive motor 31 is fixedly connected to one side inside the mounting plate 1. The output shaft of the drive motor 31 is fixedly connected to a lead screw 32. One end of the lead screw 32 is rotatably connected to the other side inside the mounting plate 1.
