When the bending block moves downward, the connecting rod three is driven downward by the circular sliding sleeve, and the annular sleeve is driven downward after the connecting rod three moves downward. Restricted by the shape of the annular sleeve, the annular sleeve forces the circular rod to extend the inner wall of the annular sleeve to slide, thereby driving the rotating plate to rotate.

This can ensure the stability and consistency of each bending process and avoid bending errors or defective products caused by unstable plate position.
[0012] The present invention has the following beneficial effects: The present invention utilizes the force when the moving block moves forward. When the moving block moves forward, it drives the push plate to contact the strip block one, and applies an extrusion force to the strip block one, thereby forcing the strip block one and the strip block two to drive the slide bar two to slide downward. After the slide bar two slides downward, it drives the bending block to move downward, so that the bending block contacts the plate and clamps the plate to fix it. In this way, the plate can be prevented from warping when the plate is folded. When the strip block one is squeezed and drives the slide bar two to move downward, the coil spring and the arc spring are pulled by the strip block one at the same time. After the folding is completed, when the strip block one is no longer subjected to the extrusion force, the pulling force on the coil spring and the arc spring disappears, thereby completing the resetting of the bending block. By effectively fixing the plate, it can be prevented from warping or moving the plate during the folding process, thereby ensuring the folding quality of the plate.
[0013] The present invention utilizes the characteristics that the inclined plate one and the inclined plate two are inclined, starts the driving motor, and the driving motor drives the threaded rod to rotate. After the threaded rod rotates, it drives the moving block to move forward. Under the limiting action of the limit rod, it can avoid the moving block from shaking during movement, thereby improving the stability of the moving block during movement. After the moving block moves, it drives the inclined plate one to move forward. The inclined plate one is limited by the inclined surface of the inclined plate two. At this time, the return spring is in a squeezed state. As the inclined plate one continues to move forward, the squeezing force exerted on the return spring is continuously released, thereby forcing the inclined plate one to move downward. When the inclined plate one moves to no longer contact the inclined plate two, the position of the inclined plate one moves to the back side of the plate to be folded, and the moving block continues to drive the inclined plate one to move forward, thereby pushing the plate to be folded forward through the inclined plate one until the plate contacts the positioning plate. In this way, the plate can be moved to the specified position, thereby ensuring the accuracy of the plate folding.
[0014] The present invention utilizes the force generated when the bending block moves downward. When the bending block moves downward, the circular sliding sleeve drives the connecting rod three to move downward. After the connecting rod three moves downward, it drives the annular sleeve downward. Restricted by the shape of the annular sleeve, the annular sleeve forces the circular rod to extend and slide on the inner wall of the annular sleeve after moving downward, thereby driving the rotating plate to rotate. While the rotating plate rotates, the connecting rod two and the arc-shaped sliding rod rotate synchronously with the rotating plate. After the arc-shaped sliding rod rotates, it drives the bending plate to move, so that the bending plate applies an upward thrust to the bottom of the plate, so that the plate completes the folding work according to the shape of the bending block, thus ensuring the accuracy and consistency of the folding of the plate.
[0015] The present invention causes the clamping plate to slide in the second slide groove while the second connecting rod rotates with the rotating plate as the midpoint. The clamping plate is pulled by the pull rope to slide in the second slide groove, and the change in the shape of the second slide groove forces the clamping plate to move toward the position of the plate, thereby completing the centering of the plate. This can ensure the accuracy of the position of the plate during folding. When the clamping plate slides in the second slide groove, the tension spring is subjected to a pulling force. After the folding is completed, the tension applied to the clamping plate disappears, thereby forcing the tension spring to complete the resetting of the clamping plate. By clamping the plate in the center, it can be ensured that the plate always remains in the correct position and angle during the bending process, and the movement or distortion of the plate during the bending process can be effectively reduced. This can ensure the stability and consistency of each bending process, and avoid bending errors or defective products caused by unstable plate position. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] For example 2, please refer to Figure 7 - Figure 8 The present invention is a plate folding device for front processing of a switch cabinet. On the basis of Example 1, the folding mechanism 3 also includes a support rod 304 fixedly connected to the inner wall of the top of the main body 101, and a rotating plate 305 is rotatably sleeved on the outer wall of the support rod 304. A second connecting rod 306 is fixedly connected to the outer wall of the rotating plate 305. The side of the second connecting rod 306 away from the rotating plate 305 is fixedly connected to the arc sliding rod 303, and the end of the arc sliding rod 303 away from the second connecting rod 306 is fixedly connected to a bending plate 307. When the rotating plate 305 rotates, the second connecting rod 306 and the arc sliding rod 303 rotate synchronously with the rotating plate 305. After the arc sliding rod 303 rotates, it drives the bending plate 307 to move, so that the bending plate 307 applies an upward thrust to the bottom of the plate, so that the plate completes the folding work according to the shape of the bending block 208, which can ensure the accuracy and consistency of the plate folding.
[0026] The folding mechanism 3 also includes a rectangular block 308 fixedly connected to the side of the rotating plate 305 away from the support rod 304, and a circular rod 309 is fixedly connected to the side of the rectangular block 308 away from the rotating plate 305. An annular sleeve 310 is slidably sleeved on the outer wall of the circular rod 309, and a connecting rod 311 is fixedly connected to the top of the annular sleeve 310. The end of the connecting rod 311 away from the annular sleeve 310 is fixedly connected to a circular sleeve 312, and the inner wall of the circular sleeve 312 is slidably connected to the outer wall of the fixed rod 102. Then, the outer wall of the circular sleeve 312 is fixedly connected to the bending block 208. By utilizing the force generated when the bending block 208 moves downward, when the bending block 208 moves downward, the circular sleeve 312 drives the connecting rod three 311 to move downward. After the connecting rod three 311 moves downward, it drives the annular sleeve 310 to move downward. Restricted by the shape of the annular sleeve 310, the annular sleeve 310 moves downward and forces the circular rod 309 to extend the inner wall of the annular sleeve 310 to slide, thereby driving the rotating plate 305 to rotate.
[0027] The folding mechanism 3 also includes a top plate 313 fixedly connected to the top of the fixed plate 103, a second slide groove 314 is provided on the top of the top plate 313, a clamping plate 315 is slidably connected in the second slide groove 314, a guide wheel 316 is fixedly connected to the top of the main body 101, a pull rope 317 is fixedly connected to the outer wall of the clamping plate 315, the pull rope 317 passes around the guide wheel 316 and is fixedly connected to the second connecting rod 306, when the second connecting rod 306 rotates with the rotating plate 305 as the midpoint, the clamping plate 315 is pulled by the pull rope 317 to slide in the second slide groove 314, and the shape of the second slide groove 314 changes, thereby forcing the clamping plate 315 to move to the position of the plate. , thereby completing the centering of the plate, which can ensure the accuracy of the position of the plate during folding. When the clamping plate 315 slides in the second slide groove 314, the tension spring 318 is subjected to a pulling force. After the folding is completed, the pulling force on the clamping plate 315 disappears, thereby forcing the tension spring 318 to complete the reset of the clamping plate 315. By centering and clamping the plate, it can be ensured that the plate always remains in the correct position and angle during the bending process, which can effectively reduce the movement or distortion of the plate during the bending process, which can ensure the stability and consistency of each bending process and avoid bending errors or defective products caused by unstable plate position.
[0028] A specific application of this embodiment is: When it is necessary to fold the plate, first place the plate to be folded on the top of the main body 101, and then start the driving motor 106. The driving motor 106 drives the threaded rod 105 to rotate. After the threaded rod 105 rotates, it drives the moving block 107 to move forward. Under the limiting action of the limiting rod 108, it can avoid the moving block 107 from shaking during movement, thereby improving the stability of the moving block 107 during movement. After the moving block 107 moves, it drives the inclined plate 112 to move forward. The inclined plate 112 is limited by the inclined surface of the inclined plate 2 113. At this time, the reset spring 111 In the squeezed state, as the inclined plate 112 continues to move forward, the squeezing force exerted on the return spring 111 is continuously released, thereby forcing the inclined plate 112 to move downward. When the inclined plate 112 moves to the point where it no longer contacts the inclined plate 213, the position of the inclined plate 112 moves to the back side of the sheet to be folded, and the moving block 107 continues to drive the inclined plate 112 to move forward, thereby pushing the sheet to be folded forward through the inclined plate 112 until the sheet contacts the positioning plate 210. In this way, the sheet can be moved to the specified position, thereby ensuring the accuracy of the sheet folding.
[0029] When the moving block 107 moves forward, it drives the push plate 114 to contact the strip block 1 204, applying an extrusion force to the strip block 1 204, thereby forcing the strip block 1 204 and the strip block 2 206 to drive the slide bar 207 to slide downward. After the slide bar 207 slides downward, it drives the bending block 208 to move downward, so that the bending block 208 contacts the plate and clamps the plate to fix it. This can avoid the plate from tilting when folding. When the strip block 1 204 is squeezed and drives the slide bar 207 to move downward, the coil spring 202 and the arc spring 205 are pulled by the strip block 1 204 at the same time. After the folding is completed, when the strip block 1 204 is no longer subjected to the extrusion force, the pulling force on the coil spring 202 and the arc spring 205 disappears, thereby completing the resetting of the bending block 208.
[0030] When the bending block 208 moves downward, the circular sliding sleeve 312 drives the connecting rod three 311 to move downward. After the connecting rod three 311 moves downward, it drives the annular sleeve 310 to move downward. Restricted by the shape of the annular sleeve 310, the annular sleeve 310 moves downward and forces the circular rod 309 to extend the inner wall of the annular sleeve 310 to slide, thereby driving the rotating plate 305 to rotate. While the rotating plate 305 rotates, the connecting rod two 306 and the arc-shaped sliding rod 303 rotate synchronously with the rotating plate 305. After the arc-shaped sliding rod 303 rotates, it drives the bending plate 307 to move, so that the bending plate 307 applies an upward thrust to the bottom of the plate, so that the plate completes the folding work according to the shape of the bending block 208.
[0031] While the connecting rod 306 rotates with the rotating plate 305 as the midpoint, the clamping plate 315 is pulled to slide in the second slide groove 314 by the pull rope 317. The change in the shape of the second slide groove 314 forces the clamping plate 315 to move toward the position of the plate, thereby completing the centering of the plate, which can ensure the accuracy of the position of the plate during folding. When the clamping plate 315 slides in the second slide groove 314, the tension spring 318 is subjected to a pulling force. After the folding is completed, the tension on the clamping plate 315 disappears, forcing the tension spring 318 to complete the reset of the clamping plate 315.
