An upper mounting plate 45 is fixedly mounted at the bottom of the movable frame 44. An upper roller 46 is rotatably mounted inside the upper mounting plate 45. Support wheels 43 are installed inside both the lower mounting plate 41 and the upper mounting plate 45. The support wheels 43 inside the upper mounting plate 45 are located at the top of the upper roller 46, and the support wheels 43 inside the lower mounting plate 41 are located at the bottom of the lower roller 42.
[0030] In practical use: A lower mounting plate 41 is installed on the surface of the frame 1. A lower roller 42 is rotatably installed inside the lower mounting plate 41. A movable frame 44 is provided inside the frame 1. An upper mounting plate 45 is installed at the bottom of the movable frame 44. An upper roller 46 is installed inside the upper mounting plate 45. Support wheels 43 are installed inside both the lower mounting plate 41 and the upper mounting plate 45. The support wheels 43 inside the upper mounting plate 45 are installed at the top of the upper roller 46, and the support wheels 43 inside the lower mounting plate 41 are installed at the bottom of the lower roller 42. When the upper roller 46 and the lower roller 42 are leveling the sheet metal, the support wheels 43 play a role in stabilizing the rollers.
[0031] Please see Figure 2 , Figure 4 The lifting mechanism 5 includes hydraulic cylinders 51 arranged around the top of the frame 1. The internal piston of the hydraulic cylinder 51 is equipped with a lifting rod 52. One end of the lifting rod 52 is fixedly installed at the four corners of the frame 1. The top of the frame 1 is provided with a lifting frame 53. The hydraulic cylinders 51 are fixedly installed around the lifting frame 53. The lifting rod 52 slides through the inside of the lifting frame 53. The movable frame 44 is fixedly installed at the bottom of the lifting frame 53.
[0032] In practical use: Hydraulic cylinders 51 are provided around the top of the machine frame 1. The piston inside the hydraulic cylinders 51 is equipped with lifting rods 52. One end of the lifting rods 52 is fixedly installed at the four corners of the machine frame 1. The hydraulic cylinders 51 are installed around the top of the lifting frame 53 and the lifting rods 52 are inserted inside the lifting frame 53. When the hydraulic cylinders 51 work, the lifting rods 52 rise and fall, thereby pushing the hydraulic cylinders 51 and the lifting frame 53 to rise and fall relative to the machine frame 1. The rise and fall of the lifting frame 53 drives the movable frame 44 to rise and fall together, thereby adjusting the distance between the upper roller 46 and the lower roller 42 at the bottom of the upper mounting plate 45, replacing the motor belt lifting adjustment method, improving the adjustment accuracy and ensuring processing requirements.
[0033] Please see Figure 2 , Figure 3 A gearbox 6 is fixedly installed on one side of both the frame 1 and the lifting frame 53. A drive motor 7 is fixedly installed on the outside of the gearbox 6. Several transmission gears 8 that mesh with each other are rotatably installed inside the gearbox 6. The output end of the drive motor 7 meshes with one of the transmission gears 8. A coupling 9 is fixedly installed on one end of the transmission gear 8. One end of the coupling 9 is connected to the lower roller 42 and the upper roller 46.
[0034] In practical use: Gearboxes 6 are fixedly installed on one side of both the frame 1 and the lifting frame 53. Drive motors 7 are fixedly installed on the outside of gearboxes 6. Multiple transmission gears 8 are meshed inside gearboxes 6. Several transmission gears 8 inside the two gearboxes 6 are connected to their respective upper rollers 46 and lower rollers 42 through couplings 9. Drive motor 7 is connected to one of the transmission gears 8 inside gearboxes 6, so that all transmission gears 8 are driven to rotate through the meshing between the gears, thereby driving the upper rollers 46 and lower rollers 42, which facilitates the leveling process of the sheet metal.
[0035] Please see Figure 3 The two ends of the lower mounting plate 41 are fixedly mounted with limiting brackets 10, and the side of the upper mounting plate 45 slides inside the limiting brackets 10.
[0036] In practical use: the two ends of the lower mounting plate 41 are fixedly installed with limiting angle brackets 10, and the side of the upper mounting plate 45 slides inside the limiting angle brackets 10. When the hydraulic cylinder 51 drives the movable frame 44 to move up and down, the side of the upper mounting plate 45 slides along the inside of the limiting angle brackets 10, so that the upper mounting plate 45 and the lower mounting plate 41 slide stably, ensuring the alignment accuracy between the rollers.
[0037] Please see Figure 2 Inspection doors 11 are installed on both sides of the frame 1, and the inspection doors 11 correspond to the hydraulic cylinders 51.
[0038] In practical use: the inspection doors 11 installed on both sides of the frame 1 correspond to the hydraulic cylinder 51, which facilitates the inspection and maintenance of the hydraulic cylinder 51.
[0039] Please see Figure 4 The top of the lifting frame 53 is equipped with a reinforcing rib plate 12.
[0040] In practical use: The reinforcing rib plate 12 installed on the top of the lifting frame 53 enhances the structural strength of the lifting frame 53.
[0041] Please see Figure 1 The hydraulic cylinder 51 and the drive motor 7 are both electrically connected to the control panel 3, and the control panel 3 is electrically connected to an external power supply.
[0042] In practical use: When the control panel 3 is connected to the external power supply, the hydraulic cylinder 51 and the drive motor 7 are powered on and controlled to run. When the control panel 3 is disconnected from the external power supply, the equipment stops running.
[0043] Hydraulic cylinders 51 are provided around the top of the machine frame 1. Lifting rods 52 are installed inside the pistons of the hydraulic cylinders 51. One end of the lifting rods 52 is fixedly installed at the four corners of the machine frame 1. The hydraulic cylinders 51 are installed around the top of the lifting frame 53 and the lifting rods 52 are inserted inside the lifting frame 53. When the hydraulic cylinders 51 work, the lifting rods 52 rise and fall, thereby pushing the hydraulic cylinders 51 and the lifting frame 53 to rise and fall relative to the machine frame 1. The rise and fall of the lifting frame 53 drives the movable frame 44 to rise and fall together, thereby adjusting the distance between the upper roller 46 and the lower roller 42 at the bottom of the upper mounting plate 45. This replaces the motor belt lifting adjustment method, improves the adjustment accuracy, and ensures processing requirements.
