Detailed implementation mode
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] The present invention provides a technical solution: as Figures 1-4 shown, in this embodiment, a plate bending machine for pressure vessel production includes a plate bending machine base 1. Two auxiliary rollers 4 are rotatably connected inside the plate bending machine base 1. Above the two auxiliary rollers 4 and inside the plate bending machine base 1 is provided a pressure roller 3. One side of the plate bending machine base 1 is fixedly connected with a transmission box 2. Inside the transmission box 2 is rotatably connected a transmission roller group 5. Between the inner walls of the transmission box 2 is fixedly connected a fixed rod 6. Outside the fixed rod 6 is provided a calibration structure. Above the transmission box 2 is fixedly connected a U-shaped mounting plate 7 and a U-shaped connecting plate 8. Between the U-shaped mounting plate 7 and the U-shaped connecting plate 8 is provided a pressure plate 13. Inside the U-shaped mounting plate 7 is provided a lifting structure for driving the pressure plate 13 to move. One side of the pressure plate 13 is a bevel structure.
[0022] When performing plate curling processing, first adjust the calibration mechanism according to the usage requirements, so that the calibration mechanism limits the moving distance of the plate outside the fixed rod 6. Then adjust the lifting mechanism to move the pressure plate 13 to the corresponding position. Then place the plate to be curled on the upper side of the transmission roller group 5 and the fixed rod 6, and make it move towards the plate bending machine base 1. Through the cooperation of the calibration mechanism and the lifting mechanism, the plate to be curled is smoothly moved to the plate bending machine base 1 and contacts the pressure roller 3 and the two auxiliary rollers 4. Further, the pressure roller 3 and the two auxiliary rollers 4 are used to curl the plate. Thus, through this plate bending machine, it is further avoided that the plate is skewed during the moving process. At the same time, by using the bevel surface of the pressure plate 13 to contact the plate, the plate with an arc surface can be effectively flattened, thereby facilitating the improvement of the quality and efficiency of plate curling.
[0023] As Figures 1-4As shown in the figure, the calibration structure includes two calibration rings 14. Both of the two calibration rings 14 are slidably connected to the outer side of the fixed rod 6. A chute 15 is formed inside the calibration ring 14. A U-shaped slider 16 is slidably connected between the inner walls of the chute 15. A second threaded rod 17 is rotatably connected to the top of the U-shaped slider 16. One end of the second threaded rod 17 extends to the outside of the calibration ring 14 and is fixedly connected to a rotary handle 18. The outer side of the second threaded rod 17 is threadedly connected to the U-shaped slider 16. A rubber pad 19 is fixedly connected to the inner side of the arc edge of the U-shaped slider 16.
[0024] By moving the calibration rings 14, the two calibration rings 14 are moved to the positions required for use. Then, rotate the rotary handle 18 to drive the second threaded rod 17 to rotate on the top of the U-shaped slider 16. Since the outer side of the second threaded rod 17 is threadedly connected to the U-shaped slider 16, the U-shaped slider 16 moves towards the fixed rod 6 and contacts it between the inner walls of the chute 15. At the same time, the rubber pad 19 is used to increase the friction between the fixed rod 6 and the U-shaped slider 16, making the fixation of the calibration ring 14 more firm.
[0025] As Figures 1-4 shown in the figure, the lifting structure includes a first threaded rod 9. The first threaded rod 9 is rotatably connected between the top of the U-shaped mounting plate 7 and the transmission box 2. A first connecting slide plate 11 is threadedly connected to the outer side of the first threaded rod 9. One side of the first connecting slide plate 11 is fixedly connected to a pressure plate 13. A servo motor 10 is fixedly installed on the top of the U-shaped mounting plate 7. The output end of the servo motor 10 extends into the U-shaped mounting plate 7 and is fixedly connected to the first threaded rod 9. A second connecting slide plate 12 is slidably connected between the inner walls of the U-shaped connecting plate 8. One side of the second connecting slide plate 12 is fixedly connected to the other side of the pressure plate 13.
[0026] The servo motor 10 drives the first threaded rod 9 to rotate between the top of the U-shaped mounting plate 7 and the transmission box 2. Further, due to the threaded connection between the first threaded rod 9 and the first connecting slide plate 11, the first connecting slide plate 11 moves between the inner walls of the U-shaped mounting plate 7. Further, through the cooperation with the second connecting slide plate 12, the pressure plate 13 is moved to the specified height.
[0027] The utility model provides a plate rolling machine for the production of pressure vessels, and the specific working principle is as follows: when performing plate curling processing, first move the calibration rings 14 according to the usage requirements, so that the two calibration rings 14 move to the positions required for use. Then rotate the handle 18 to drive the second threaded rod 17 to rotate on the top of the U-shaped slider 16. Since the outer side of the second threaded rod 17 is threadedly connected to the U-shaped slider 16, the U-shaped slider 16 moves towards the fixed rod 6 between the inner walls of the chute 15 and contacts it. At the same time, the rubber pad 19 is used to increase the friction force between the fixed rod 6 and the U-shaped slider 16, so that the calibration rings 14 are firmly fixed. Then drive the first threaded rod 9 to rotate between the top of the U-shaped mounting plate 7 and the transmission box 2 through the servo motor 10. Further, due to the threaded connection between the first threaded rod 9 and the first connecting slide plate 11, the first connecting slide plate 11 moves between the inner walls of the U-shaped mounting plate 7. Further, through the cooperation with the second connecting slide plate 12, the pressure plate 13 moves to the specified height. Then place the plate to be curled on the top of the transmission roller group 5 and the fixed rod 6, and make it move towards the plate rolling machine base 1 and contact the pressure roller 3 and the two auxiliary rollers 4. Further start the plate rolling machine base 1, and use the pressure roller 3 and the two auxiliary rollers 4 to perform curling processing on the plate.
[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
