Figure 6 At this time, the first fixed position pipe winding roller 401 rotates clockwise, and the second fixed position pipe winding roller 402 rotates counterclockwise. The rotating sleeve 207 is used to fix the first gear shaft 201, the second gear shaft 202 and the third gear shaft 203 and prevent the first gear shaft 201, the second gear shaft 202 and the third gear shaft 203 from rotational wear, thereby reducing maintenance costs.

[0038] Combined with attachment Figure 4 , Attachment Figure 5 and attached Figure 6 :

[0039] The double vertical plate frame 1 is provided with an adjustable arm assembly 3 that rotates coaxially with the second fixed position pipe roller 402. The adjustable arm assembly 3 is rotatably connected to a movable position pipe roller 7 near the second fixed position pipe roller 402.

[0040] Through this structure, the threaded rod 304 is rotated to adjust the distance between the first rotating shaft 303 and the second rotating shaft 301. Since the closed end of the U-shaped rotating arm 302 is rotationally connected to the third gear shaft 203, the position of the first rotating shaft 303 rotating around the third gear shaft 203 is adjusted, and then the position of the movable position pipe roller 7 is adjusted.

[0041] Combined with attachment Figure 2 , Attachment Figure 5 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 9 , Attachment Figure 10 , Attachment Figure 11 and attached Figure 12 :

[0042] An adjustable bending bracket 5 and a plate bender 6 for bending the plate are provided on the other side of the double vertical plate frame 1. A first extension shaft 205 is provided on the end of the second gear shaft 202 exposed from the second special-shaped plate 104. A second extension shaft 206 is provided on the end of the third gear shaft 203 exposed from the second special-shaped plate 104. A support shaft 8 is provided on the side of the second special-shaped plate 104 away from the first special-shaped plate 102 and is in the same horizontal plane as the second extension shaft 206. A third extension shaft 307 is provided on the end of the first rotating shaft 303 exposed from the second special-shaped plate 104.

[0043] The adjustable bending bracket 5 includes a horizontal plate 501 and a rotating plate 502. The horizontal plate 501 and the rotating plate 502 are rotatably connected via the second extension shaft 206. The end of the horizontal plate 501 away from the rotating plate 502 is sleeved with the support shaft 8. The end of the rotating plate 502 away from the horizontal plate 501 is rotatably connected to the third extension shaft 307. The end of the rotating plate 502 close to the horizontal plate 501 is provided with an angle compensation block 503 located on the rotating plate 502.

[0044] The sheet bender 6 includes a sleeve 601 rotatably connected to the first extension shaft 205, a C-shaped extension rod 602 is provided on the side of the sleeve 601 close to the first gear shaft 201, the other end of the C-shaped extension rod 602 is fixedly connected to a connecting block 603, a bending knife 605 is provided at the bottom of the connecting block 603, and a pull rod 604 is provided at the top of the connecting block 603.

[0045] By rotating the threaded rod 304 through the above structure, the distance between the first rotating shaft 303 and the second rotating shaft 301 is adjusted, and the angle between the rotating plate 502 and the horizontal plate 501 is adjusted. Figure 12 Since the threaded rod 304 cannot be adjusted to a vertical state, the angle compensation block 503 is used to compensate the angle to achieve a common bending angle of the metal plate, such as ninety degrees. At this time, pull the pull rod 604 to make the bending knife 605 close to the connection between the horizontal plate 501 and the rotating plate 502, and the metal plate can be bent.

[0046] Example 1: When curling and bending a metal plate or a metal tube, rotate the threaded rod 304 to adjust the movable tube roller 7 to a horizontal height close to the first fixed tube roller 401, place the metal plate or metal tube on the movable tube roller 7 and the first fixed tube roller 401, and place it below the second fixed tube roller 402, then rotate the threaded rod 304 to adjust the movable tube roller 7 upwards so that the movable tube roller 7, the first fixed tube roller 401 and the second fixed tube roller 402 clamp the metal plate or metal tube. Since the metal plate or metal tube has metallic properties, continuing to rotate the threaded rod 304 will cause a certain deformation. At this time, use an electric drill connected to the electric drill chuck 204, refer to the attached Figure 6 At this time, the first fixed position pipe winding roller 401 rotates clockwise, and the second fixed position pipe winding roller 402 rotates counterclockwise, thereby transmitting the metal plate or metal tube to the movable position pipe winding roller 7, and then using an electric drill to drive the electric drill chuck 204 to rotate in the opposite direction, thereby reciprocatingly transmitting the metal plate or metal tube, during which the threaded rod 304 is continuously rotated to adjust the movable position pipe winding roller 7 upward, thereby performing curling and bending.

[0047] Example 2: When bending a metal plate, rotate the threaded rod 304 according to the required bending angle, adjust the angle between the rotating plate 502 and the horizontal plate 501, place the required bending part of the metal plate on the rotating plate 502 and the horizontal plate 501, pull the pull rod 604, and move the bending knife 605 close to the connection between the horizontal plate 501 and the rotating plate 502 to bend the metal plate.

[0048] The above description of the present invention and its embodiments is non-limiting, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above description and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
