Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] In one embodiment, referring to Figures 1-6 , a bending device comprises a base 1, a feeding mechanism 2 and a bending mechanism 3;

[0023] The feeding mechanism 2 comprises support side plates 4 arranged at the end of the base 1, the support side plates 4 being arranged on the right end of the upper surface of the base 1 in a forward and backward manner and being inclined upward to the right, the top of the support side plates 4 being provided with feeding grooves 5, the feeding grooves 5 being in an open state at the top, and the commonly purchased metal sheet 28 in the production process being wound outside the roller, the front and rear ends of the roller being placed in the feeding grooves 5, so that the roller can be supported by the feeding grooves 5 and adaptively rotate and unwind when the metal sheet 28 is drawn out;

[0024] The bending mechanism 3 is arranged at the end of the base 1 away from the feeding mechanism 2, and comprises a vertical column 12 fixedly connected with the base 1. The end of the vertical column 12 is provided with a processing platform 13 horizontally arranged above the left side of the base 1. The upper end of the vertical column 12 is fixedly connected with the four corners of the lower surface of the processing platform 13. A gap 29 is arranged in the middle of the processing platform 13 and faces forward and backward. A guide column 17 is vertically arranged on the middle of the upper surface of the base 1 and faces forward and backward. A supporting plate 18 is arranged below the guide column 17 and faces left and right. The upper surface of the middle of the two supporting plates 18 is provided with a forward and backward facing extrusion block 19. When the extrusion block 19 moves upward, it will pass through the gap 29 and move above the processing platform 13. A pressing plate 20 is slidably connected above the guide column 17 and faces left and right. The left and right sides of the two pressing plates 20 are fixedly connected with the front and back ends of a fixed side plate 21 which faces forward and backward. The spacing between the two fixed side plates 21 is slightly larger than the left and right width of the extrusion block 19, so that the extrusion block 19 will move between the two fixed side plates 21 after moving upward. At this time, the two fixed side plates 21 and the extrusion block 19 will bend the flat metal sheet 28 into an upward protruding structure. With repeated extrusion and bending, the metal sheet 28 is extruded into multiple protrusions with the same spacing, realizing the bending of the wavy metal sheet 28.

[0025] In one case of the embodiment, since the metal sheet 28 is wound outside the roller, after the metal sheet 28 is pulled out, the metal sheet 28 itself will have a certain curvature, which will affect the subsequent bending process. Therefore, a straightening assembly 11 is arranged on the side of the supporting side plate 4.

A pressing roller 6 is rotatably connected with the side of the rotating bracket 7 away from the rotating shaft 8 and faces forward and backward. When the rotating bracket 7 rotates counterclockwise, the pressing roller 6 can fall between the two supporting rollers 10. The pressing roller 6 bends the metal sheet 28 in the opposite direction by its own weight, thereby realizing straightening. When the straightening assembly 11 is not needed, the rotating bracket 7 can be rotated clockwise, so that the pressing roller 6 can fall below the right side of the supporting side plate 4, thereby facilitating the installation of the metal sheet 28.

[0026] In one case of the embodiment, the upper surface of the processing platform 13 is fixedly connected with a fixed plate 14 on the right side, the middle part of the fixed plate 14 is rotatably connected with a feeding roller 15 arranged in front and back directions, the surface of the feeding roller 15 is provided with a certain elastic rubber material, so that after the metal sheet 28 is inserted between the feeding roller 15 and the processing platform 13, when the feeding roller 15 rotates, the feeding roller 15 drives the metal sheet 28 to move, thereby achieving the effect of feeding, and a driving motor 16 is arranged on the front fixed plate 14, the output shaft of the driving motor 16 is fixedly connected with the front end of the feeding roller 15, and the driving motor 16 drives the feeding roller 15 to rotate.
