Under the restriction of the threaded rod 304, the distance between the folding roller 310 and the pressure plate 209 can be adjusted to fold the tank plates of different thicknesses. The auxiliary unit 400 is placed on the side of the fixed unit 200 away from the folding unit 300. The auxiliary unit 400 includes a sliding ball 405, which is used to smoothly transport the panels placed on the processing table 100 to the fixed unit 200 and the folding unit 300, avoiding time-consuming and labor-intensive manual handling by operators.

[0033] During use, when folding the automobile fuel tank, the plate is transported to the fixing unit 200 and the folding unit 300 through the auxiliary unit 400. Under the restriction of the fixing unit 200, the plate can be pressed and fixed, and under the restriction of the folding unit 300, the plate can be folded. The internal electronic control components of the fixing unit 200 and the folding unit 300 can be controlled by the control panel 101.

[0034] Example 2 Reference Figure 3 and Figure 4 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment is further optimized based on the above embodiment, specifically as follows: The fixing unit 200 includes a frame 201 fixedly mounted on the top surface of the processing table 100, a bracket 202 fixedly mounted on the side wall of the frame 201, a motor 203 fixedly mounted on the end of the bracket 202, a rotating rod 204 fixedly mounted on the output end of the motor 203, a convex plate 205 fixedly mounted on the outer wall of the rotating rod 204, a first magnetic ring 206 fixedly mounted on the top surface of the frame 201, a sliding rod 207 slidingly arranged inside the frame 201, and a fixedly mounted end of the sliding rod 207. The second magnetic ring 208 and the end of the slide rod 207 away from the second magnetic ring 208 are fixedly installed with a pressure plate 209, and the side wall of the pressure plate 209 is fixedly installed with a slide column 210. The top surface of the processing table 100 is provided with a slide groove 211, and a slider 212 is slidably arranged inside the slide groove 211. A folding frame 213 is fixedly installed on the outer wall of the slider 212, and a prism 214 is slidably arranged inside the folding frame 213. The outer wall of the prism 214 is provided with a spring 215, and the end of the prism 214 is fixedly installed with a centering plate 216.

[0035] Among them, the first magnetic ring 206 and the second magnetic ring 208 magnetically repel each other, the outer wall of the slide rod 207 is set to slide inside the first magnetic ring 206, and the convex disk 205 is elliptical. Under its restriction, when the elliptical convex disk 205 no longer presses the top surface of the pressure plate 209, under the restriction of magnetic repulsion, the first magnetic ring 206 pushes the second magnetic ring 208, the slide rod 207 and the pressure plate 209 to reset the pressure plate 209.

[0036] Among them, the side wall of the folding frame 213 is provided with an inclined groove, and is slidably arranged with the outer wall of the slide column 210. The bottom of the center plate 216 is slidably arranged with the top surface of the processing table 100. Under its restriction, the downward moving slide column 210 can slide and squeeze the inside of the folding frame 213, so that the folding frame 213 drives the prism 214, the spring 215 and the center plate 216 to move. Since the bottom of the center plate 216 is slidably arranged with the top surface of the processing table 100, under its restriction, the two center plates 216 can stably move in opposite directions.

[0037] During use, when the automobile fuel tank is being processed, the plate needs to be folded. At this time, the plate needs to be accurately fixed to improve the folding accuracy. The plate is transported to the bottom of the pressure plate 209 through the auxiliary unit 400. At this time, the motor 203 is started, and the rotating rod 204 fixedly installed at its output end rotates accordingly. The rotating rod 204 drives the convex disc 205 fixedly installed on its outer wall to rotate accordingly. Since the convex disc 205 is set in an elliptical shape, under its restriction, the top surface of the pressure plate 209 is squeezed, so that the pressure plate 209 drives the sliding rod 207 fixedly installed on the top surface to slide inside the frame 201. When the pressure plate 209 moves downward, its The slide column 210 fixed on the side wall moves downward accordingly. Since the side wall of the folding frame 213 is provided with an oblique groove, and the outer wall of the slide column 210 slides with the oblique groove of the side wall of the folding frame 213, under its restriction, the inside of the folding frame 213 can be squeezed. Since the slider 212 fixed on the bottom of the folding frame 213 slides with the slide groove 211 provided on the top surface of the processing table 100, under its restriction, the two folding frames 213 move in opposite directions. Since the outer wall of the prism 214 slides with the inside of the folding frame 213, under its restriction, the moving folding frame 213 drives the prism 214, the spring 215 and the center plate 216 to move accordingly. The two center plates 216 always clamp the plate in the center, and the clamping force applied to the outside of the plate increases until the pressure plate 209 is pressed against the outer wall of the prism 214. The bottom contacts the top surface of the plate, and the cam 205 no longer rotates at this time. The pressure plate 209 cooperates with the two centering plates 216 to center and fix the plate on the top surface of the processing table 100. The folding work can be performed accurately through the folding unit 300. When the folding is completed, the reverse function of the motor 203 is started, and the cam 205 no longer presses the top surface of the pressure plate 209. Under the magnetic repulsion restriction of the first magnetic ring 206 and the second magnetic ring 208, it pushes the slide bar 207 and the pressure plate 209 upward to reset the pressure plate 209. At the same time, under the restriction of the slide column 210, the two centering plates 216 move in the opposite direction to reset.

[0038] Example 3 Reference Figure 5 and Figure 6 , which is the third embodiment of the present invention. Different from the above embodiment, this embodiment is further optimized on the basis of the above embodiment, specifically as follows: The folding unit 300 includes a telescopic rod 301 fixedly installed inside the processing table 100, a movable plate 302 is fixedly installed on the end of the telescopic rod 301, a fixed block 303 is fixedly installed on the top surface of the movable plate 302, a threaded rod 304 is rotatably connected inside the fixed block 303, a sleeve plate 305 is sleeved on the outer wall of the threaded rod 304, a sleeve ring 306 is fixedly installed on the end of the sleeve plate 305, a rod frame 307 is slidably arranged inside the sleeve ring 306, a vertical plate 308 is fixedly installed on the top surface of the sleeve plate 305, a rotating shaft 309 is fixedly installed on the side wall of the vertical plate 308, and a folding roller 310 is rotatably connected to the outer wall of the rotating shaft 309.

[0039] Among them, the end of the rod frame 307 is fixedly installed on the top surface of the movable plate 302. There are two rod frames 307, which are symmetrically distributed about the center line of the top surface of the movable plate 302. Under the sliding restriction of the ring 306 and the rod frame 307, the rotating threaded rod 304 can drive the sleeve plate 305 to move, so as to adjust the distance between the folding roller 310 and the pressure plate 209.

[0040] When in use, after the fixing unit 200 has fixed the fuel tank panel, the distance between the folding roller 310 and the pressure plate 209 needs to be adjusted according to the thickness of the panel. At this time, the threaded rod 304 is rotated. Since the ring 306 fixedly installed at the end of the sleeve plate 305 slides with the outer wall of the rod frame 307 fixedly installed on the top surface of the movable plate 302, under its restriction, the rotating threaded rod 304 can drive the sleeve plate 305 sleeved on its outer wall. The moving sleeve plate 305 drives the vertical plate 308, the rotating shaft 309 and the folding roller 310 to move, and adjust the distance between the folding roller 310 and the pressure plate 209. At this time, the telescopic rod 301 is started, which pulls the movable plate 302 upward, and the folding roller 310 folds the panel. Since the folding roller 310 is rotatably connected to the rotating shaft 309, under its restriction, it can avoid scratching the panel when folding. This structure can fold the panel, and can fold the fuel tank panels of different thicknesses.

[0041] Example 4 Reference Figure 7 and Figure 8 , which is the fourth embodiment of the present invention. Different from the above embodiments, this embodiment is further optimized on the basis of the above embodiments, specifically as follows: Auxiliary unit 400, the auxiliary unit 400 includes a sliding tube 401 fixedly installed inside the processing table 100, a third magnetic ring 402 is fixedly installed on the inner wall of the sliding tube 401, a fourth magnetic ring 403 is slidingly arranged inside the sliding tube 401, a top column 404 is fixedly installed on the side wall of the fourth magnetic ring 403, and a sliding ball 405 is slidably connected to the end of the top column 404.

[0042] During use, when the automobile fuel tank is being folded, the plate needs to be transported. In order to reduce the wear between the plate and the top surface of the processing table 100 and the manual handling, it is necessary to assist in its transportation. The plate is placed on the top surface of the sliding ball 405. Since the outer wall of the sliding ball 405 is rotatably connected to the inside of the top column 404, under its restriction, the plate can be assisted in transportation to reduce the friction between the plate and the top surface of the processing table 100. When the pressing plate 209 presses down and fixes the plate, the plate squeezes the sliding ball 405, and the sliding ball 405 drives the top column 404. The fourth magnetic ring 403 slides toward the inside of the slide tube 401 to keep the processing table 100 in a flat state. When the plate is folded, the pressure plate 209 no longer presses the plate. Under the magnetic repulsion restriction of the fourth magnetic ring 403 and the third magnetic ring 402, the fourth magnetic ring 403, the top column 404 and the sliding ball 405 can be pushed toward the outside of the slide tube 401 to transport the folded plate. This structure can transport the plate smoothly, avoid the need for human handling, and avoid wear on the plate.

[0043] Example 5 Reference Figures 1 to 8 , which is the fifth embodiment of the present invention. Different from the above embodiments, this embodiment provides a method for using the hemming forming device for automobile fuel tank processing, which is applicable to the hemming forming device for automobile fuel tank processing described in any of the above embodiments, and includes the following steps: S1. When processing the fuel tank of an automobile, it is necessary to fold the plate. At this time, the plate needs to be fixed accurately to improve the folding accuracy. The plate is transported to the bottom of the pressure plate 209 through the auxiliary unit 400. At this time, the motor 203 is started, and the rotating rod 204 fixedly installed at its output end rotates accordingly. The rotating rod 204 drives the convex disc 205 fixedly installed on its outer wall to rotate accordingly. Since the convex disc 205 is set in an elliptical shape, it squeezes the top surface of the pressure plate 209 under its restriction, so that the pressure plate 209 drives the sliding rod 207 fixed on the top surface to slide inside the frame 201. When the pressure plate 209 moves downward, its side wall The fixed slide 210 moves downward accordingly. Since the side wall of the folding frame 213 is provided with an oblique groove, and the outer wall of the slide 210 slides with the oblique groove of the side wall of the folding frame 213, under its restriction, the inside of the folding frame 213 can be squeezed. Since the slider 212 fixedly installed at the bottom of the folding frame 213 slides with the slide groove 211 provided on the top surface of the processing table 100, under its restriction, the two folding frames 213 move in opposite directions. Since the outer wall of the prism 214 slides with the inside of the folding frame 213, under its restriction, the moving folding frame 213 drives the prism 214, the spring 215 and the center plate 216 to move accordingly. When the center plate 216 contacts the plate, the two center plates 216 clamp the plate in the center. At this time, the clamping force of the center plate 216 is small, and the plate can be pushed to align the folding part with the side of the pressure plate 209 away from the slide column 210, and the next folding work can be carried out. As the pressure plate 209 continues to move downward, the slide column 210 continues to squeeze the folding frame 213, causing the folding frame 213 to slide on the outer wall of the prism 214 and compress the spring 215 set on the outer wall of the prism 214. The two center plates 216 always clamp the plate in the center, and the clamping force applied to the outside of the plate increases until the bottom of the pressure plate 209 When the cam 205 contacts the top surface of the plate, the cam 205 no longer rotates, and the pressure plate 209 cooperates with the two centering plates 216 to center and fix the plate on the top surface of the processing table 100. The folding unit 300 can accurately perform the folding work. When the folding is completed, the reverse function of the motor 203 is started, and the cam 205 no longer presses the top surface of the pressure plate 209. Under the magnetic repulsion restriction of the first magnetic ring 206 and the second magnetic ring 208, it pushes the slide bar 207 and the pressure plate 209 upward to reset the pressure plate 209. At the same time, under the restriction of the slide column 210, the two centering plates 216 move in the opposite direction to reset. After the cam 310 is in the process of being moved, the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved, and the cam 310 is in the process of being moved. S3. When the automobile fuel tank is being folded, the plate needs to be transported. In order to reduce the wear between the plate and the top surface of the processing table 100 and the need for manual handling, the plate needs to be assisted in transportation. The plate is placed on the top surface of the sliding ball 405. Since the outer wall of the sliding ball 405 is rotatably connected to the inside of the top column 404, under its restriction, the plate can be assisted in transportation to reduce the friction between the plate and the top surface of the processing table 100. When the pressing plate 209 presses down and fixes the plate, the plate is squeezed against the sliding ball 405, and the sliding ball 405 drives the top column 404 and the sliding ball 405 to move. The fourth magnetic ring 403 slides toward the inside of the slide tube 401, so that the processing table 100 is in a flat state. When the folding of the plate is completed, the pressure plate 209 no longer presses the plate. Under the magnetic repulsion restriction of the fourth magnetic ring 403 and the third magnetic ring 402, the fourth magnetic ring 403, the top column 404 and the sliding ball 405 can be pushed toward the outside of the slide tube 401 to transport the folded plate. This structure can smoothly transport the plate, avoid the need for human handling, and avoid wear on the plate.
