Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1:

[0024] In this embodiment, the metal sheet folding assembly includes a hydraulic cylinder 10, a transmission rack 11, a driven gear 12 and a folding plate 16. A connecting plate 9 is welded to the top of the supporting base plate 8. The hydraulic cylinder 10 is fixed to the top of the supporting base plate 8 by bolts. The connecting plate 9 is located on one side of the hydraulic cylinder 10. A transmission rack 11 is fixed to the output end of the hydraulic cylinder 10. The two ends of the transmission rack 11 are meshed and connected with the driven gear 12. In order to effectively ensure the transmission effect of the driven gear 12, a connecting shaft 17 is fixed to the inner side of the driven gear 12, and one side of the connecting shaft 17 is rotatably connected to the connecting plate 9.

[0025] When folding, the metal sheet is placed on the lining support plate 7 and located between the two folding plates 16. The transmission rack 11 can be driven downward by the hydraulic cylinder 10 to move the two folding plates 16 closer to each other until the folding is completed. Finally, the transmission rack 11 is reset to move the transmission rack 11 upward, so that the two folding plates 16 are moved away from each other, waiting for the next metal sheet to be folded.

[0026] A connecting frame 13 is provided on one side of the driven gear 12, a folding push block 14 is fixed on the top of the connecting frame 13, a folding extension plate 15 is provided on the ends of the two folding push blocks 14 close to each other, and the driven gear 12 and the connecting frame 13, the folding push block 14 and the folding extension plate 15 are connected by butterfly screws, so that the driven gear 12 and the connecting frame 13, the folding push block 14 and the folding extension plate 15 can be conveniently disassembled and separated, and parts can be quickly replaced, and a folding plate 16 is fixed on the ends of the two folding extension plates 15 close to each other, and extension ribs 19 are fixed on both ends of the folding push block 14, and the pushing effect of the folding push block 14 on the folding extension plate 15 during the folding process is further extended by the extension ribs 19, so that the cooperation between the folding push block 14 and the folding extension plate 15 is more stable, thereby ensuring the folding effect of the folding plate 16.

[0027] A guide plate 18 is fixed to the side of the transmission rack 11 close to the connecting plate 9, and a slide groove is provided on the side of the connecting plate 9 close to the transmission rack 11. The side of the guide plate 18 away from the transmission rack 11 is slidably connected in the slide groove, thereby helping to limit the moving direction of the transmission rack 11, making the operation of the transmission rack 11 more stable.

[0028] Embodiment 2:

[0029] Please refer to Figure 4 and Figure 5 This embodiment is an improvement made on the basis of the first embodiment. A push rod 20 is fixed to the top of the transmission rack 11, and a soft pad 21 is pasted on the top of the push rod 20. The setting of the soft pad 21 can prevent the push rod 20 from scratching the metal bridge frame, thereby ensuring the processing effect. A through groove for the push rod 20 and the soft pad 21 to move up and down is provided on the inner side of the lining support plate 7, so that when the transmission rack 11 drives the two folding plates 16 away from each other, it can simultaneously drive the push rod 20 and the soft pad 21 to move upward, so that the soft pad 21 moves out of the through groove and pushes the folded metal bridge frame to move upward, thereby separating the metal bridge frame from the lining support plate 7.

[0030] In summary, the metal bridge processing equipment provided by the present invention, when working, is loaded through the conveyor frame 1, and then the metal sheet is cut and pre-processed through the cutting component 3, and punched through the punching component 6;

[0031] When folding is required, the metal sheet is placed on the lining support plate 7 and located between the two folding plates 16. The hydraulic cylinder 10 is then started to drive the transmission rack 11 to move downward, thereby driving the two driven gears 12 to rotate in the opposite direction, so that the two folding plates 16 are brought closer to each other until the folding is completed. Finally, the transmission rack 11 is reset to move upward, thereby moving the two folding plates 16 away from each other. At the same time, the transmission rack 11 will move upward with the push rod 20 and the cushion 21, so that the top of the cushion 21 lifts up the metal bridge.
