By using the moving holes 7, the extension baffle 85 can be conveniently limited to improve its stability during movement and avoid its rotation with the threaded block 86 during movement. A limiting component 8 is fixedly installed at the center of the bottom of the working plate 1;

[0021] See also Figure 1 and Figure 3 The pressing assembly 6 includes a fixing frame 61, which is fixedly welded to the top of the working plate 1, a threaded cylinder 64 is fixedly inlaid at the center of the top of the fixing frame 61, a threaded column 65 is threadedly connected to the inner cavity of the threaded cylinder 64, and a push plate 63 is fixedly welded to the bottom of the threaded column 65;

[0022] See also Figure 1 and Figure 3 The left and right sides of the top of the fixing frame 61 are slidably penetrated by limit rods 62, and a pressure plate 66 is fixedly welded between the bottom of the limit rods 62. A reset spring 67 is fixedly connected to the surface of the limit rod 62 and located between the top of the pressure plate 66 and the bottom of the fixing frame 61. By using the reset spring 67, the pressure plate 66 can be reset so that it can automatically recover after being pressed down, which saves the time of manual operation recovery and improves work efficiency.

[0023] See also Figure 3 A limit baffle is fixedly welded on the top of the limit rod 62. By using the limit baffle, the limit rod 62 can be limited to prevent it from sliding off the surface of the fixing frame 61, thereby improving its stability during movement. A hand wheel is fixedly welded on the top of the threaded column 65. By using the hand wheel, the user can conveniently rotate the threaded column 65, thereby saving the physical effort of manual operation.

[0024] See also Figure 4 and Figure 5 The limit assembly 8 includes a motor 81, which is fixedly mounted on the bottom of the working plate 1. The output shaft of the motor 81 is fixedly connected to a threaded rod 82, and a threaded block 86 is provided on the surface of the threaded rod 82;

[0025] See also Figure 5The left and right sides of the threaded block 86 are fixedly connected with connecting plates 87, and a sleeve plate 83 is fixedly welded on the side of the connecting plate 87 away from the threaded block 86. A return spring 84 is fixedly welded on the bottom of the inner cavity of the sleeve plate 83, and an extension baffle 85 is fixedly welded on the top of the return spring 84. By using the extension baffle 85, the plate can be shielded and limited, which makes it convenient for the staff to quickly locate the bending position, and the bending position can be accurately fixed to avoid shaking.

[0026] When in use, place the plate on the top of the working plate 1, then start the motor 81, and drive the threaded rod 82 to rotate through its output shaft, thereby driving the threaded block 86 on its surface to move, and then driving the sleeve plate 83 to move. During the movement of the sleeve plate 83, it drives the extension baffle 85 inside it to move inside the moving hole 7. When it moves to a suitable position, stop the motor 81, and then push the plate backward so that the rear side of the plate contacts the front side of the extension baffle 85, thereby limiting the position. After the limiting is completed, rotate the threaded column 65, and under the action of the threaded cylinder 64, it drives the push plate 63 to descend, and then pushes the pressing plate 66 downward until the pressing plate 6 The bottom of 6 is in close contact with the plate. When the pressure plate 66 contacts the top of the extension baffle 85, the extension baffle 85 moves downward and retracts into the inside of the moving hole 7. At this time, the return spring 84 is compressed until the plate is fixed on the top of the working plate 1, and then the hydraulic cylinder 4 is started to push the bending plate 5 upward and rotate upward through the extension of its telescopic end, so as to bend the plate. After the bending is completed, the threaded column 65 is rotated to drive the push plate 63 to reset. Under the action of the reset tension spring 67, the pressure plate 66 is driven to move upward and reset. After the plate is removed, the return spring 84 is reset, driving the extension baffle 85 to bounce up again for limiting, thereby achieving the bending effect.
