[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figure 1-4 A metal sheet bending device includes a worktable 1, a slide rail 2 on one side of the upper end of the worktable 1, a movable platform 3 mounted on the upper end of the slide rail 2, an extension plate 6 forming a lifting structure with the worktable 1 via a first hydraulic cylinder 7, and a sliding structure with the worktable 1 via a slide groove 5. The movable platform 3 can be adjusted back and forth via the first hydraulic cylinder 7, allowing it to accommodate metal sheets of different lengths. A fastening rod 4 is mounted on one end of the movable platform 3, and a slide groove 5 is formed on the inner wall of one end of the worktable 1, with the extension plate 6 mounted on one end of the slide groove 5. The movable platform 3 forms a sliding structure with the worktable 1 via the slide rail 2, and the movable platform 3 is threaded to the fastening rod 4. The fastening rod 4 installed in the device can be tightened to fix the placed metal plate. A first hydraulic cylinder 7 is installed at one end of the extension plate 6. A limiting frame 8 is installed at the upper end of the worktable 1. A second hydraulic cylinder 9 is installed at the upper end of the limiting frame 8. A fastening plate 10 is installed at the lower end of the second hydraulic cylinder 9. The fastening plate 10 forms a lifting structure with the limiting frame 8 through the first hydraulic cylinder 7. The limiting frame 8 is threadedly connected to the worktable 1. The fastening plate 10 in the device can clamp the bent metal plate and maintain the stability of the metal plate when bent. A load-bearing frame 11 is installed at the upper end of the worktable 1.
