The folding machine can fold according to set parameters and generally has functions to adjust the folding angle, folding line position, and number of folds to meet different production requirements.
[0003] In the prior art, generally, a sheet is manually placed on the top surface of the folding machine. After placement, the sheet is pushed so that the top of the sheet contacts the limit inside the folding machine to achieve positioning of the sheet. However, since the positioning device in the prior art can only control the entering depth of the sheet and cannot align the center point of the sheet with the center point of the folding knife, when the folding machine bends the sheet for a long time, due to the uncalibrated position of the sheet, the folding knife will be unevenly stressed each time the folding machine stamps and bends the sheet. Long-term stamping will result in low precision of the hydraulic rod or the folding knife. Content of the Utility Model

Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment 1
[0020] Please refer to Figure 4 - Figure 5 , the present utility model discloses a positioning device for a plate bending machine, including a bending machine 1 and a placing table 2. The placing table 2 is installed on one side surface of the bending machine 1. A moving groove 3 is opened on the top surface of the placing table 2. A ball slider 4 is installed on the inner wall of the moving groove 3. A bidirectional screw 5 is installed on one side surface of the placing table 2. A driving motor 6 is installed on one side surface of the placing table 2. A contact component is installed on the top surface of the placing table 2. A bending component is installed on one side surface of the bending machine 1.
[0021] The placing table 2 is fixedly connected to the bending machine 1. There are two ball sliders 4, and the two ball sliders 4 are equidistantly distributed on the inner wall of the moving groove 3. The outer surface of the ball slider 4 is slidably connected to the inner wall of the moving groove 3. The output end of the driving motor 6 is fixedly connected to one end of the bidirectional screw 5. One end of the bidirectional screw 5 extends from the outer surface of the placing table 2 to its inner wall. The outer surface of the bidirectional screw 5 is rotatably connected to the inner wall of the ball slider 4. The bidirectional screw 5 is rotatably connected to the placing table 2.
[0022] The positioning component includes a positioning block 7. A rotating groove 8 is installed on one side surface of the positioning block 7. A pulley 9 is installed on the inner wall of the rotating groove 8. A transmission shaft 10 is installed on the top surface of the pulley 9. A driving motor 11 is installed on the top surface of the positioning block 7. The positioning block 7 is installed on the top surface of the ball slider 4.
[0023] There are two positioning blocks 7, which are respectively distributed on the top surfaces of the two ball sliders 4. On one side surface of each positioning block 7, there is a corresponding rotating groove 8. A number of pulleys 9 are evenly distributed on the inner wall of the rotating groove 8, and the pulleys 9 are movably rotatably connected to the inner wall of the rotating groove 8.
[0024] When the two ball sliders 4 drive the positioning blocks 7 to move, at this time, the pulleys 9 installed on the inner wall of the rotating groove 8 will contact one side surface of the plate. And because the positioning blocks 7 are in a moving state at this time, the positioning blocks 7 will push the plate to move on the top surface of the support plate through the pulleys 9. Since there are two positioning plates of the ball sliders 4, when the two positioning plates move simultaneously, the pulleys 9 on one side surface will contact the one side and the other side of the plate respectively. Through the extrusion movement of the pulleys 9, the plate is positioned at the center of the placement table 2, thus realizing the automatic centering function of the plate. Embodiment 2
[0025] Based on the above Embodiment 1, please refer to Figure 1 - Figure 3 , the bending assembly includes a hydraulic rod 12. The bottom surface of the hydraulic rod 12 is installed with an extrusion plate 13. The bottom surface of the extrusion plate 13 is installed with a folding knife 14. The top surface of the placement table 2 is installed with a placement plate 15. The hydraulic rod 12 is installed on one side surface of the bending machine 1.
[0026] There are two hydraulic rods 12, and the two hydraulic rods 12 are evenly distributed on one side surface of the bending machine 1. The top surface of the extrusion plate 13 is fixedly connected to the bottom surfaces of the two hydraulic rods 12.
[0027] There are two placement plates 15, and the two placement plates 15 are evenly distributed on the top surface of the placement table 2. The placement plates 15 are slidably connected to the placement table 2, and the top surface of the placement plates 15 is in movable contact with the bottom surface of the positioning blocks 7.
[0028] After finishing this, at this time, the hydraulic rod 12 is started. When the hydraulic rod 12 is started, it will drive the extrusion plate 13 installed on the bottom surface of its output to move downward. And the folding knife 14 is installed on the bottom surface of the extrusion plate 13. At this time, the moving folding knife 14 will extrude the plate due to the movement, thus realizing the function of bending the plate.
[0029] Working principle and usage process of the utility model: When the sheet metal bending machine 1 is needed, place the sheet metal to be bent on the top surface of the placement plate 15. After placement, start the drive motor 6. When the drive motor 6 starts, it will drive the bidirectional screw 5 installed at its output end to rotate. Since the ball sliders 4 are installed on the outer surface of the bidirectional screw 5, when the bidirectional screw 5 rotates, the two ball sliders 4 installed on its outer surface will move inward along the bidirectional screw 5. The positioning blocks 7 are installed on the top surfaces of the two ball sliders 4. At this time, the positioning blocks 7 will move along with the ball sliders 4. When the two ball sliders 4 drive the positioning blocks 7 to move, the pulleys 9 installed on the inner wall of the rotating groove 8 will come into contact with one side surface of the sheet metal. And because the positioning blocks 7 are in a moving state at this time, the positioning blocks 7 will push the sheet metal to move on the top surface of the support plate through the pulleys 9. Since there are two ball slider positioning plates 4, when the two positioning plates move simultaneously, the pulleys 9 on one side surface will come into contact with one side and the other side of the sheet metal. Through the extrusion and movement of the pulleys 9, the sheet metal is centered on the placement table 2, thus realizing the automatic centering function of the sheet metal.
[0030] When the pulley 9 pushes the sheet metal to the center point of the placement plate 15, start the drive motor 11 at this time. When the drive motor 11 starts, it will drive the transmission shaft 10 at its output end to rotate. At this time, the rotating transmission shaft 10 will drive the pulley 9 installed on its outer surface to rotate. Since the pulley 9 is in contact with one side surface of the sheet metal at this time, when the pulley 9 rotates, it will push the sheet metal to move on the surface of the placement plate 15. At this time, the moving sheet metal will move to directly below the pressing plate 13. And because the existing edge folding machines all have a limiting function, at this time, the moving sheet metal will come into contact with the limiter, and the movement of the sheet metal is restricted by the limiter. At this time, one side surface of the sheet metal with restricted movement will be aligned with one side of the limiter. After alignment, start the hydraulic rod 12 at this time. When the hydraulic rod 12 starts, it will drive the pressing plate 13 installed on the bottom surface of its output end to move downward. And the folding knife 14 is installed on the bottom surface of the pressing plate 13. At this time, the moving folding knife 14 will extrude the sheet metal due to the movement, thus realizing the function of bending the sheet metal.
