An L-shaped frame 3 is fixedly arranged on the rear side of the top of the stamping box 1, and a stamping plate 8 is arranged at the bottom of the top of the L-shaped frame 3 through a first hydraulic cylinder 5. The stamping plate 8 includes an intermediate plate 9, and movable plates 10 are movably installed on both sides of the intermediate plate 9 through a rotating shaft. A limiting mechanism 11 is arranged between the top of the intermediate plate 9 and the movable plate 10, and the limiting mechanism 11 includes a U-shaped frame 19 and an L-shaped rod 20. The U-shaped frame 19 is fixedly arranged on both sides of the top of the intermediate plate 9. The movable plate 10 can be fixed to the intermediate plate 9 through the provided limiting mechanism 11, so that the intermediate plate 9 and the movable plate 10 can be driven to descend by the first hydraulic cylinder 5, so that the metal plate can be flattened and corrected, which is convenient for subsequent stamping of the metal plate and improves the processing efficiency of the distribution cabinet.

[0022] In this embodiment, the adjustment mechanism 6 includes a slide groove 17, which is opened inside the convex plate, and a screw rod 16 is installed inside the slide groove 17 for limiting rotation. A servo motor 15 is fixedly installed at one end of the convex plate, and the output shaft of the servo motor 15 is fixedly connected to one end of the screw rod 16. The baffle plate 7 is in a "T" shape, and the bottom end of the baffle plate 7 is limitedly slidably installed inside the slide groove 17. The bottom end of the baffle plate 7 is screwed on the screw rod 16 through a screw hole. The baffle plate 7 can be adjusted by the servo motor 15 and the screw rod 16, which is convenient for limiting the position of metal plates of different specifications, thereby improving the stability of the metal plates.

[0023] In this embodiment, rotating rollers 12 are provided on both sides of the top of the inner side of the stamping box 1 for limited rotation, and legs 2 are fixedly provided at the four corners of the bottom of the stamping box 1. A second hydraulic cylinder 14 is fixedly provided inside the legs 2, and an adjusting plate 13 is fixedly provided on the top of the output rod of the second hydraulic cylinder 14. The adjusting plate 13 is slidably installed inside the stamping box 1. The rotating rollers 12 can rotate when stamping the metal sheet, thereby reducing the wear of the metal sheet; the adjusting plate 13 can be raised and lowered by the second hydraulic cylinder 14, so that the adjusting plate 13 can support the metal sheet, thereby preventing the metal sheet from sinking and causing the bending position to shift, and also facilitating the support of the flattening process.

[0024] In this embodiment, limit rods 4 are symmetrically fixedly arranged on both sides of the top of the middle plate 9, and the limit rods 4 are slidably installed inside the top of the L-shaped frame 3. The first hydraulic cylinder 5 is fixedly arranged on the top of the L-shaped frame 3, and the output rod of the first hydraulic cylinder 5 is fixedly connected to the top of the middle plate 9. The first hydraulic cylinder 5 is arranged between the limit rods 4 on both sides. The middle plate 9 can be limited by the limit rods 4 to improve the stability of the middle plate 9 during the lifting and lowering process. The middle plate 9 can be lifted and lowered by the first hydraulic cylinder 5, which is convenient for subsequent flattening and stamping operations on the metal sheet.

[0025] In this embodiment, one end of the L-shaped rod 20 is slidably installed inside the U-shaped frame 19, and a third hydraulic cylinder 18 is fixedly arranged on one side of the U-shaped frame 19 corresponding to the top of the middle plate 9. The output rod of the third hydraulic cylinder 18 is fixedly connected to the L-shaped rod 20, and one end of the L-shaped rod 20 is arranged on the top of the movable plate 10. The third hydraulic cylinder 18 can drive the L-shaped rod 20 to move horizontally, so that one end of the L-shaped rod 20 moves to the top of the movable plate 10, thereby limiting the movable plate 10 and preventing the movable plate 10 from rotating at both ends of the middle plate 9, which is convenient for the subsequent flattening operation of the metal plate.

[0026] When using the non-destructive stamping device of the distribution cabinet, according to the specifications of the metal sheet, the servo motor 15 is started. The servo motor 15 drives the baffle 7 to move on the convex plate through the screw 16, adjusts the distance between the two baffles 7, places the metal sheet between the baffles 7 on both sides, and limits the two ends of the metal sheet by the baffle 7. If it needs to be flattened, the third hydraulic cylinder 18 is started. The third hydraulic cylinder 18 drives one end of the L-shaped rod 20 to move inside the U-shaped frame 19, so that one end of the L-shaped rod 20 moves to the top of the movable plate 10, and the movable plate 10 is limited by the L-shaped rod 20 to prevent the movable plate 10 from rotating at both ends of the middle plate 9. The second hydraulic cylinder 14 and the first hydraulic cylinder 5 are started. The second hydraulic cylinder 14 drives the adjusting plate 13 to rise, and adjusts the adjusting plate 13 to the top of the stamping box 1, so that the top of the adjusting plate 13 and the top of the stamping box 1 are in the same plane. The first hydraulic cylinder 5 drives the stamping plate 8 to descend, which can flatten the metal sheet. When the specification of the metal sheet is greater than the stamping When the specifications of the plate 8 are adjusted, the metal plate is manually moved, and the metal plate is flattened for multiple times. After the flattening is completed, the metal plate is straightened, and the L-shaped rod 20 is driven by the third hydraulic cylinder 18 to move in the opposite direction. One end of the L-shaped rod 20 is removed from the top of the movable plate 10, so that the movable plate 10 can rotate at both ends of the middle plate 9, and the middle plate 9 is driven to descend by the first hydraulic cylinder 5, and the metal plate is squeezed by the middle plate 9. At the same time, the adjusting plate 13 is driven by the second hydraulic cylinder 14 to descend synchronously with the metal plate and the middle plate 9. The adjusting plate 13 can prevent the metal plate from sinking and causing the bending position to shift. The set rotating roller 12 can rotate with the descent of the metal plate to reduce the wear between the metal plate and the stamping box 1. At this time, the movable plate 10 is adjusted to a vertical state under the action of the stamping box 1 and the metal plate. After the stamping is completed, the adjusting plate 13 is driven to rise by the second hydraulic cylinder 14, so that the formed plate can be ejected from the inside of the stamping box 1, which can improve the processing efficiency of the distribution cabinet.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
