The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0020] See also Figure 1-3 In order to solve the problem that the bending equipment can only fold the plate once in one bending work, and it takes multiple operations to bend a whole plate into a U shape, resulting in low bending efficiency and inconvenience in use, this technical solution is designed. The detailed technical solution is as follows;

[0021] A bridge processing device includes a base 1, support frames 2 are installed on the front and rear side walls of the base 1, a hydraulic cylinder 3 is installed on the support frame 2, a connecting frame 4 is installed on the telescopic end of the hydraulic cylinder 3, a bottom end adjustment structure is installed on the upper wall of the base 1, and a top end adjustment structure is installed on the connecting frame 4. The bottom end adjustment structure and the top end adjustment structure are symmetrically arranged, and two limit forming structures are symmetrically installed on the bottom end adjustment structure;

[0022] Specifically, the bottom adjustment structure and the top adjustment structure both include a center plate 5, and first cylinders 6 are installed on the left and right side walls of the center plate 5, and edge plates 7 are installed on the telescopic ends of the first cylinders 6;

[0023] Specifically, the two limiting forming structures each include a fixing frame 8, which is mounted on the lower wall of the edge plate 7. A second cylinder 9 is inserted into the fixing frame 8. A third cylinder 10 is mounted on the telescopic end of the second cylinder 9. A U-shaped frame 11 is mounted on the telescopic end of the third cylinder 10. A rotating column 12 is movably mounted on the U-shaped frame 11. A centering limiting assembly is mounted on the fixed end of the third cylinder 10.

[0024] Specifically, the centering limit assembly includes a fourth cylinder 13, which is installed on the side wall of the fixed end of the third cylinder 10, and a limit plate 14 is installed on the telescopic end of the fourth cylinder 13;

[0025] It should be noted that the metal sheet is placed on the center plate 5 and the edge plate 7 on the base 1, and then the fourth cylinders 13 on both sides are controlled to retract until the limit plates 14 are attached to the ends of the metal sheet, so that the metal sheet is centered on the center plate 5 and the edge plate 7, and then the hydraulic cylinder 3 is controlled to retract so that the center plate 5 and the edge plate 7 in the top adjustment structure are pressed against the upper wall surface of the metal sheet to clamp the metal sheet and prevent the metal sheet from moving, and the second cylinder 9 is controlled to retract to adjust the distance between the rotating column 12 and the edge plate 7 so that the distance is the same as the thickness of the metal sheet, and then the third cylinder 10 is controlled to extend to drive the U-shaped frame 11 and the rotating column 12 to rise until the rotating column 12 is attached to the metal sheet and the bending of the metal sheet is completed. The metal sheet can be bent at two positions at the same time, and the sheet can be bent into a U shape in one bending operation, thereby improving the bending efficiency. When the rotating column 12 is attached to the metal sheet and rises, the rotating column 12 moves on the U-shaped frame 11 to prevent the rotating column 12 and the metal sheet from wearing each other.

[0029] As a preference, further, the connecting frame 4 is an L-shaped structure;

[0030] Preferably, further, the length of the rotating column 12 is greater than the length of the edge plate 7 .
