[0034] In specific use, when the staff places the mold in the cavity of the mold groove 13 of the workbench, the top wall surface of the top plate 17, the mold can be moved up and down by the up-and-down movement of the top plate 17, which facilitates the staff to replace the mold, and the limiting device can limit the displacement of the guard plate during the bending process.

[0035] In summary, by arranging the lifting device and the limiting device, the top plate 17 can be moved up and down by the lifting device, the mold can be moved by the up-and-down movement of the top plate 17, which facilitates the staff to replace the mold, and the limiting device can limit the displacement of the guard plate during the work, compared with the prior art, has the characteristics of convenient use and simple structure.

[0036] As shown in Figure 2 and Figure 3 , a mold groove 13 is arranged on the top wall surface of the workbench 10, two threaded holes 14 are arranged on the bottom wall surface in the cavity of the mold groove 13, and a side groove 27 is arranged on the left and right side wall surfaces in the cavity of the threaded hole 14.

[0037] The top wall surfaces of the two first threaded rods 18 are rotationally connected with the top plate 17, and the first threaded rod 18 is threadedly connected with the threaded hole 14.

[0038] A bottom plate 26 is fixedly installed on the bottom wall surface of each of the two motors 19, and the bottom plate 26 corresponds in shape to the threaded hole 14 and the side groove 27. The motor 19 is electrically connected with the power supply and the switch.

[0039] In specific use, when the output ends of the two motors 19 rotate, the first threaded rod 18 can be driven to rotate, the rotation of the two first threaded rods 18 can drive the top plate 17 to move up and down, the top plate 17 cannot rotate due to the limitation of the two first threaded rods 18, the bottom plate 26 is limited by the threaded hole 14 and the side groove 27, so that the motor 19 cannot rotate, and the first threaded rod 18 moves up and down, thereby driving the mold placed on the top wall surface of the top plate 17 in the cavity of the workbench 10 to move.

[0040] Therefore, the top plate 17, the first threaded rod 18, the motor 19, the bottom plate 26, the threaded hole 14 and the side groove 27 are arranged, so that the two top plates 17 are driven to move up and down by the rotation of the two motor 19 output ends, and the mold is driven to move up and down, and the mold can be taken when the mold moves up, which is convenient and simple in structure.

[0041] As shown in Figure 2 , Figure 4 and Figure 5 , the top wall surface of the workbench 10 is fixedly provided with a moving plate 22 on both sides, and the side wall surface of the two moving plates 22 close to each other is in a hollow state.

The fixed rod 24 is located in the cavity of the spring 25, and the moving rod 20 and the rubber plate 21 are movably connected with the penetrating portions of the moving rod 20 and the rubber plate 21.

[0044] In specific use, when the staff rotates the two handles 29, the second threaded rod 28 is driven to rotate, and the rotation of the second threaded rod 28 drives the two moving plates 22 to move close to or away from each other. The two moving plates 22 can move through the opposite threads at the front and rear ends of the second threaded rod 28. The moving plate 22 is limited by the limiting groove 15, and the movement of the two moving plates 22 drives the fixed rod 24 to move, and the movement of the fixed rod 24 drives the moving rod 20 to move, and the movement of the moving rod 20 drives the rubber plate 21 to move. The staff lifts up the two moving rods 20, and then places the guard plate in the cavity on the mold. The top wall surface of the mold corresponds to the position of the top wall surface of the workbench 10, and then the rubber plate 21 is moved downward under the tension of the spring 25, and the guard plate is pressed to limit the guard plate.

[0045] Therefore, by setting the moving plate 22, the handle 29, the second threaded rod 28, the rubber plate 21, the fixed rod 24, the spring 25, the moving rod 20, the rubber plate 21 and the limiting groove 15, the two rubber plates 21 can play a limiting role, and different specifications of the guard plates can be limited by moving the rubber plate 21.
