Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, specifically to an anti-springback plate rolling machine. Background Technology

[0002] Plate rolling machines are important equipment that use rollers to continuously bend and shape metal sheets, and are widely used in pressure vessels, pipe manufacturing, shipbuilding, and steel structure processing. Traditional plate rolling machines apply pressure to the sheet metal through the coordinated action of multiple rollers, causing it to undergo plastic deformation and ultimately form the desired arc or cylindrical structure. However, in actual processing, due to the elastic properties of metal materials, the sheet metal often exhibits varying degrees of springback after roll forming, causing the radius of curvature of the final formed workpiece to deviate from the preset target value, seriously affecting product accuracy.

[0003] A search revealed an anti-rebound plate rolling machine with authorization announcement number CN219766619U. In operation, a second button switch controls the first telescopic rod to operate, pushing the anti-rebound plate downwards. The plate is then stopped by a limiting groove, preventing springback during bending and facilitating faster bending operations, thus improving the machine's efficiency. The protective pad, in direct contact with the plate during stopping, protects it from scratches caused by the anti-rebound plate, enhancing the machine's safety.

[0004] However, the existing plate rolling machines use limiting grooves to limit the plate material. In actual use, the rebound of the plate material mainly occurs at both ends. Existing plate rolling machines do not have good positioning or limiting functions at these points. Therefore, we propose an anti-rebound plate rolling machine. Utility Model Content

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0025] like Figures 1-3As shown, this embodiment proposes an anti-rebound plate rolling machine, including a bottom frame 1. A support frame 2 is detachably connected to the surface of the bottom frame 1. A movable block 6 is slidably connected to the inner side of the support frame 2. An upper roller 3 is rotatably connected to the inner side of the movable block 6. A lower roller 4 is rotatably connected to the inner side of the support frame 2. An anti-rebound structure 5 is connected to the outer surface of the support frame 2. An adjustment structure 7 is connected between the movable block 6 and the support frame 2. A motor 8 is fixedly connected to the outer surface of the bottom frame 1. A first gear 10 is rotatably connected to the outer surface of the support frame 2. Pulleys 11 are fixedly connected to the output end of the motor 8 and the outer surface of the first gear 10. A transmission belt 12 is wound between the two sets of pulleys 11. A second gear 13 is meshed with the outer surface of the first gear 10. The second gear 13 is fixedly connected to the lower roller 4, and both are rotatably connected to the support frame 2. A cover 9 is detachably connected to the outer side of the support frame 2 near the transmission belt 12.

[0026] The motor 8 drives the pulley 11 to rotate, which causes another set of pulleys 11 to rotate. The rotation of the pulley 11 drives the first gear 10 to rotate. The rotation of the first gear 10 drives the other two sets of second gears 13 to rotate. The second gear 13 is fixedly connected to the lower roller 4. Both the second gear 13 and the lower roller 4 are rotatably connected to the support frame 2.

[0027] The anti-rebound structure 5 includes a groove 51 formed on the outer surface of the support frame 2. A slider 52 is slidably connected to the inner side of the support frame 2 corresponding to the groove 51. An electric cylinder 53 is fixedly connected to the outer surface of the support frame 2 corresponding to the slider 52. An extension rod 54 is fixedly connected to one side of the outer surface of the slider 52. A positioning post 55 is rotatably connected to the outer surface of the extension rod 54.

[0028] The slider 52 slides along the length of the groove 51. The output end of the electric cylinder 53 is fixedly connected to the slider 52, and the output end of the electric cylinder 53 passes through the support frame 2 to the inside of the groove 51. The output end of the electric cylinder 53 moves back and forth along its own length. The positioning column 55 is parallel to the upper roller 3 and the support frame 2. The maximum distance that the slider 52 can slide in the groove 51 is less than or equal to the maximum stroke of the electric cylinder 53.

[0029] In this embodiment, during use, the position of the positioning post 55 can be freely adjusted by extending or retracting the electric cylinder 53. The positioning post 55 positions and guides the two ends of the rolled-up sheet, thereby preventing the two ends of the sheet from springing back first and effectively avoiding the occurrence of sheet springback. While positioning and guiding, a certain top force can be provided at both ends of the sheet, thus making the sheet roll forming effect better. Example 2

[0030] like Figure 4As shown, based on Embodiment 1, an adjustment structure 7 is also proposed, which includes a threaded column 71 rotatably connected to the upper end of the movable block 6. A rotating part 72 is fixedly connected to the top of the threaded column 71. A through plate 73 is fixedly connected to the upper end of the movable block 6. A scale 74 is opened on the outer surface of the through plate 73.

[0031] The threaded column 71 is rotatably connected to the movable block 6 via a bearing. The surface of the support frame 2 is provided with a slot for the movable block 6 to slide up and down. The through plate 73 is slidably connected to the support frame 2. The threaded column 71 passes through the support frame 2 and is threadedly connected to the support frame 2. The height of the movable block 6 can be adjusted by turning the rotating part 72 in both directions. The upper roller 3 is rotatably connected to the movable block 6 via a bearing.

[0032] In this embodiment, the rotating part 72 can be freely rotated forward or backward according to the user's actual needs during use, thereby freely adjusting the height of the movable block 6. At the same time, the setting of the scale 74 can make the height of the movable blocks 6 at both ends of the upper roller 3 more accurately approach the same, thereby making the posture of the upper roller 3 and the interval between the lower roller 4 more stable, which can greatly reduce the generation of errors.

[0033] In summary, the working principle of this utility model is as follows:

[0034] During use, the user can place the sheet material to be bent between the upper roller 3 and the lower roller 4 and drive the corresponding pulley 11 to rotate via the motor 8. This set of pulleys 11 drives another set of pulleys 11 to rotate via the transmission belt 12. The other set of pulleys 11 drives the first gear 10 to rotate. The rotation of the first gear 10 drives the other two sets of second gears 13 to rotate in the opposite direction. The rotation of the second gears 13 drives the lower roller 4 to rotate, thereby bending the sheet material during the conveying process.

[0035] During the bending process of the sheet metal, the electric cylinder 53 can be extended to push the slider 52 to slide inside the groove 51. The slider 52 drives the extension rod 54 to move until the positioning post 55 is in contact with the outer surface of the bent sheet metal. As the sheet metal moves, the positioning post 55 will rotate accordingly, thereby providing positioning and guidance for the sheet metal and preventing the springback at both ends of the sheet metal. At the same time, the electric cylinder 53 can slightly push the slider 52 so that the positioning post 55 provides a certain pushing force to the surface of the sheet metal, thereby effectively preventing the springback at both ends of the sheet metal during the bending and rolling process, resulting in a better final sheet metal product.

[0036] Meanwhile, when it is necessary to adjust the height of the upper roller 3, the user can rotate the rotating part 72 in the forward or reverse direction. The rotating part 72 drives the threaded column 71 to rotate accordingly. Under the rotation of the threaded column 71, the movable block 6 moves up or down. The up and down movement of the movable block 6 will drive the through plate 73 to move up and down accordingly. During the movement of the through plate 73, the scale 74 can make it easy for the user to observe the height position of the movable block 6, so that the height of the movable blocks 6 at both ends of the upper roller 3 can be precisely adjusted and controlled, thereby greatly reducing the error generated during the plate rolling process.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
