[0001] This invention relates to the field of plate forming technology, and more particularly to a plate rolling machine and a plate rolling method. Background Technology

[0002] In the existing technology, metal sheets are generally wound into cylinders using a winding machine, and the plate roller is an important component of the winding machine; the plate roller is also called a steel roller, which is divided into hollow roller and solid roller, and roller with shaft and roller without shaft.

[0003] The invention disclosed in application number 201922064615.1 is a steel plate winding forming roller, including a winding device body; the bottom of the winding device body is provided with a mounting base, and frames are provided on both the left and right sides of the mounting base. A winding steel roller is connected between the two frames, and bearings are respectively installed at the left and right ends of the winding steel roller. The frames are provided with transmission holes adapted to the bearings; a drive structure is installed inside the transmission holes; a correction cylinder with its opening facing the winding steel roller is provided on the side of one frame opposite to the bearing, and a stripping cylinder is connected to the side of the correction cylinder away from the frame. A baffle plate is provided on the other side of the correction cylinder; an auxiliary pressure roller is installed on one side of the winding steel roller.

[0004] However, the existing steel plate winding forming rollers are prone to positional displacement during use. The forming rollers can only be removed after the brackets at both ends of the guide roller used for installation after forming are removed, which makes unloading difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a plate rolling machine and a plate rolling method to address the shortcomings of the prior art.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A plate rolling machine includes a machine base, on which a lower guide roller and front and rear side rollers are located on either side of the lower guide roller. An upper guide roller is positioned at the top of the lower guide roller for winding the formed plate. The surfaces of the upper and lower guide rollers are respectively formed with serrated surface textures to increase friction with the steel plate. The upper guide roller can rotate in both directions, and the upper and lower guide rollers clamp and press the steel plate forward or backward. The lower guide roller, front side rollers, and rear side rollers are radially arranged around the upper guide roller. The front side rollers can bend the steel plate by moving radially towards the upper guide roller, and the rear side rollers can also bend the steel plate by moving radially towards the upper guide roller.

[0007] Furthermore: the machine is also equipped with a roller mounting bracket and an inner support plate for installing the upper guide roller, as well as a support swing mechanism that drives the roller mounting bracket to swing longitudinally; the inner end of the upper guide roller is rotatably mounted on the inner support plate, and the roller mounting bracket provides movable support for the outer end of the upper guide roller; the machine is equipped with a pair of side support seats for installing the lower guide roller, the front side roller, and the rear side roller.

[0008] Furthermore: the support swing mechanism includes a movable groove formed on the top of the outer side support, the movable groove is fitted with a hinge shaft, the bottom of the roller mounting bracket is formed with a connecting leg, the connecting leg is hinged to the hinge shaft, and the connecting leg is able to swing around the hinge shaft.

[0009] Furthermore: a telescopic drive module and a module support base for mounting the telescopic drive module are provided on one side of the machine. The body of the telescopic drive module is rotatably mounted on the module support base.

[0010] Furthermore: the telescopic drive module is a telescopic servo electric cylinder.

[0011] Furthermore: the side support is provided with a first mounting seat for mounting the guide roller, a first roller drive seat for mounting the front side roller, and a second roller drive seat for mounting the rear side roller. The first roller drive seat and the second roller drive seat are respectively inclinedly arranged on both sides of the first mounting seat, and bearing seats are respectively mounted on the first roller drive seat and the second roller drive seat.

[0012] Furthermore, the side support seat is formed with a first inclined mounting groove for mounting the first roller drive seat and a second inclined mounting groove for mounting the second roller drive seat. The first roller drive seat can move along the length direction of the first inclined mounting groove to adjust its position, and the second roller drive seat can move along the length direction of the second inclined mounting groove to adjust its position.

[0013] Furthermore: The machine is equipped with an inner support frame, which is used to install the inner end of the guide roller.

[0014] A plate rolling method includes the following steps: Step 1: Insert the steel plate to be wound between the upper guide roller and the lower guide roller, and clamp the steel plate by the upper guide roller and the lower guide roller; Step 2: Rotate the guide roller clockwise to position the steel plate in the coil position, lower the side rear roller to the desired position, and raise the side front roller to the desired position to pre-bend the steel plate. Step 3: The front side roller descends to the desired position, the rear side roller rises to the desired position, and the guide roller rotates counterclockwise to roll the steel plate; Step 4: The steel plate is rolled to the required length, the side and rear rollers descend to the required position, and the guide rollers rotate counterclockwise to move the steel plate to the required position; Step 5: The side and rear rollers rise to pre-bend the steel plate; Step Six: The side rear roller descends to the desired position, the side front roller rises to the desired position, and the guide roller rotates clockwise to roll the steel plate; Step 7: Lower the front side roller to the desired position, and rotate the upper guide roller counterclockwise so that the seam faces upward; Step 8: The front and rear side rollers rise simultaneously, and the top-wound roller is rolled up, reducing the seam.

[0015] The beneficial effects of this invention are as follows: The machine base is equipped with a guide roller and side front rollers and side rear rollers located on both sides of it. These guide rollers are radially arranged around the guide roller. They can guide and support the forming roller during the steel plate winding process, restricting the lateral movement of the forming roller, thereby effectively preventing the roller from shifting position during use and improving the accuracy and quality of the rolled plate. The machine base is equipped with a bracket swinging mechanism that drives the roller mounting bracket to swing longitudinally. When unloading is required, the roller mounting bracket can be swinged longitudinally by the bracket swinging mechanism, thereby changing the position of the guide roller. Unlike the traditional method of removing the brackets at both ends of the guide roller, the forming roller can be easily removed, greatly simplifying the unloading process and improving unloading efficiency.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1-7 As shown, a plate rolling machine includes a machine base 1. The machine base 1 is equipped with a guide lower roller 29 and side front rollers 21 and side rear rollers 22 located on the front and rear sides of the guide lower roller 29. A guide upper roller 2 is provided on the top of the guide lower roller 29 for winding the plate after forming. The surfaces of the guide upper roller 2 and the guide lower roller 29 are respectively formed with serrated surface textures to increase the friction with the steel plate. The guide upper roller 2 can rotate in both directions, and the guide upper roller 2 and the guide lower roller 29 clamp and press the steel plate forward or backward. The guide lower roller 29, the side front rollers 21 and the side rear rollers 22 are respectively arranged radially around the guide upper roller 2. The side front roller 21 can bend the steel plate by moving in the radial direction of the guide upper roller 2, and the side rear roller 22 can bend the steel plate by moving in the radial direction of the guide upper roller 2.

[0026] During the forming process, the steel plate forms an arc shape by sequentially passing the front side roller 21, the lower guide roller 29, and the second support roller. It is then wound around the upper guide roller 2, and with the upper guide roller 2 as the axis, a cylindrical roller structure is continuously formed.

[0027] The machine base 1 is equipped with a lower guide roller 29 and two side front rollers 21 and side rear rollers 22 located on either side of it. These guide rollers are radially arranged around the upper guide roller 2. They can guide and support the forming roller during the steel plate winding process, restrict the lateral movement of the forming roller during forming, thereby effectively preventing the roller from shifting position during use and improving the accuracy and quality of the rolled plate.

[0028] The machine base 1 is equipped with a roller mounting bracket 14 for mounting the guide roller 2, an inner support plate 3, and a bracket swing mechanism 10 for driving the roller mounting bracket 14 to swing longitudinally. The inner end of the guide roller 2 is rotatably mounted on the inner support plate 3, and the roller mounting bracket 14 provides movable support for the outer end of the guide roller 2. When unloading is required, the roller mounting bracket 14 can be swinged longitudinally by the bracket swing mechanism 10, exposing the outer end of the guide roller 2. At this time, it is not movablely supported by the roller mounting bracket 14, and the gravure roller sleeved on the guide roller 2 can be removed from the guide roller 2. Unlike the traditional method of removing the brackets at both ends of the guide roller 2, the forming roller can be easily removed, greatly simplifying the unloading process and improving unloading efficiency.

[0029] A plate rolling method specifically includes the following steps: Step 1: Insert the steel plate to be wound between the upper guide roller 2 and the lower guide roller 29, and clamp the steel plate by the upper guide roller 2 and the lower guide roller 29; Step 2: The guide roller 2 rotates clockwise to position the steel plate in the coil position, the side rear roller 22 descends to the desired position, and the side front roller 21 rises to the desired position to pre-bend the steel plate. Step 3: The front side roller 21 descends to the desired position, the rear side roller 22 rises to the desired position, and the upper guide roller 2 rotates counterclockwise to roll the steel plate. Step 4: The steel plate is rolled to the required length, the side rear roller 22 is lowered to the required position, and the guide roller 2 rotates counterclockwise to move the steel plate to the required position; Step 5: The side rear roller 22 rises to pre-bend the steel plate; Step 6: The side rear roller 22 descends to the desired position, the side front roller 21 rises to the desired position, and the guide roller 2 rotates clockwise to roll the steel plate. Step 7: The front side roller 21 descends to the desired position, and the upper guide roller 2 rotates counterclockwise so that the seam faces upward; Step 8: The front side roller 21 and the rear side roller 22 rise simultaneously, top-coiling the prepared roller to reduce the seam.

[0030] The above-mentioned plate rolling scheme has the following advantages; 1. The finished roll has a smaller seam than traditional rolls.

[0031] 2. The finished roll greatly reduces the unevenness of the left and right end faces.

[0032] 3. Effectively reduces the phenomenon of uneven edges at the seams after rolling.

[0033] 4. With the seam facing upwards, it is suitable for connecting to the next welding process, realizing an automated process.

[0034] The machine base 1 is equipped with a pair of side support seats 11 for mounting the guide roller 29, the front side roller 21, and the rear side roller 22. Each side support seat 11 has a first mounting seat 23 for mounting the guide roller 29, a first roller drive seat 24 for mounting the front side roller 21, and a second roller drive seat 25 for mounting the rear side roller 22. The first roller drive seat 24 and the second roller drive seat 25 are respectively inclinedly positioned on both sides of the first mounting seat 23, and each is equipped with a bearing seat 26. The machine base 1 uses the pair of side support seats 11 to uniformly mount the guide roller 29, the front side roller 21, and the rear side roller 22, forming a symmetrical frame support structure. The first roller drive seat 24 and the second roller drive seat 25 are respectively inclinedly positioned on both sides of the first mounting seat 23, so that the front side roller 21 and the rear side roller 22 are symmetrically inclined and distributed around the guide roller 2. This tilted structure can provide a lateral wrapping constraint on the steel plate and forming roller during the winding process. It not only restricts the lateral translation of the roller, but also generates a radial force through the tilt angle to counteract the lateral thrust during steel plate winding, further reducing the risk of roller deviation. It is especially suitable for thick steel plates or high-tension winding scenarios.

[0035] Preferably, the side support 11 is formed with a first inclined mounting groove 27 for mounting the first roller drive seat 24 and a second inclined mounting groove 28 for mounting the second roller drive seat 25. The first roller drive seat 24 can move along the length direction of the first inclined mounting groove 27 to adjust its position, and the second roller drive seat 25 can move along the length direction of the second inclined mounting groove 28 to adjust its position. The first roller drive seat 24 can move along the length direction of the first inclined mounting groove 27, and the second roller drive seat 25 can move along the length direction of the second inclined mounting groove 28, so that the positions of the front side roller 21 and the rear side roller 22 can be flexibly adjusted according to processing requirements. For example, by changing the distance, inclination angle, or relative spacing between the front side roller 21 and the upper guide roller 2, and between the rear side roller 22 and the upper guide roller 2, the winding requirements of steel plates with different thicknesses, widths, or radii of curvature can be precisely adapted. Steel plate winding is a dynamic process, and the diameter of the rollers gradually increases with the increase of the number of winding layers. By adjusting the position of the guide rollers through the inclined mounting slots, the constraint range and pressure of the guide rollers on the printing rollers can be adjusted in real time during the winding process, thus avoiding guide failure caused by changes in the diameter of the printing rollers.

[0036] Preferably, telescopic cylinders can be arranged along the length direction of the first inclined mounting groove 27 and the second inclined mounting groove 28 respectively. The telescopic cylinders are connected to the corresponding first roller drive seat 24 and second roller drive seat 25. The position of the first roller drive seat 24 and the second roller drive seat 25 in the corresponding inclined mounting groove can be adjusted by the telescopic movement of the telescopic cylinders to adapt to the winding requirements of steel plates with different thicknesses, widths or curvature radii.

[0037] Furthermore, a rolling bearing 31 is installed at the inner end of the guide roller 2, and an inner support plate 3 for installing the inner end of the guide roller 2 is provided on the inner side support seat 11 located on the inner side. The inner support plate 3 has a built-in servo motor, and the servo motor drives the guide roller 2 to rotate through a transmission structure composed of a transmission belt.

[0038] Preferably, the bottom of the inner support plate 3 is also formed with an arc-shaped slot 33 that mates with the first roller drive seat 24 and the second roller drive seat 25. The arc-shaped slot 33 at the bottom of the inner support plate 3 mates with the first roller drive seat 24 and the second roller drive seat 25 to form a structural clearance and cooperation space. Since the first and second roller drive seats 25 can be moved and adjusted along the inclined mounting groove, the curved surface design of the arc-shaped slot 33 can adapt to the outer contour of the drive seat at different adjustment positions, avoiding mechanical interference between the support plate and the drive seat.

[0039] When unloading the formed printing roller, the roller mounting bracket 14 is movably connected to the inner end of the guide roller 2, meaning the roller mounting bracket 14 provides movable support for the guide roller 2. After the roller mounting bracket 14 swings outward, the front end of the guide roller 2 is not stopped and is exposed. At this time, the printing roller can be clamped and then movably removed from the front end of the guide roller 2, thus achieving unloading. Unloading can be achieved without disassembling the brackets at both ends of the guide roller 2.

[0040] Specifically, the support swing mechanism 10 includes a movable groove 12 formed on the top of the outer side support seat 11. A hinge shaft 13 is mounted on the movable groove 12. A connecting leg 15 is formed at the bottom of the roller mounting bracket 14. The connecting leg 15 is hinged to the hinge shaft 13 and can swing around the hinge shaft 13. The movable groove 12 of the outer side support seat 11 is hinged to the connecting leg 15 of the roller mounting bracket 14 via the hinge shaft 13, forming a stable rotation fulcrum. The movable groove 12 allows the connecting leg 15 at the bottom of the roller mounting bracket 14 to swing. During unloading, the roller mounting bracket 14 swings outward from an upright position to a horizontal position, and simultaneously the connecting leg 15 is inserted into the movable groove 12. At this time, the roller mounting bracket 14 does not provide active support to the front end of the guide roller 2. The roller can then be clamped and can be movably removed from the front end of the guide roller 2, thus achieving unloading. Unloading can be achieved without disassembling the supports at both ends of the guide roller 2.

[0041] The side support 11 is equipped with a servo motor, which drives the guide roller 29 to rotate through a transmission structure consisting of a transmission belt.

[0042] Furthermore, a tilted swing telescopic cylinder 16 and a cylinder support 17 for mounting the swing telescopic cylinder 16 are provided on one side of the machine base 1. The cylinder body of the swing telescopic cylinder 16 is rotatably mounted on the cylinder support 17. The drive end of the swing telescopic cylinder 16 is hinged to the roller mounting bracket 14. The swing telescopic cylinder 16 can drive the roller mounting bracket 14 to swing around the hinge axis 13 through the extension and retraction of the piston rod. Since the printing roller has a certain weight, a high-torque swing telescopic cylinder 16 is provided on the machine base 1 to drive the roller mounting bracket 14 to swing around the hinge axis 13. The direction of its driving force forms a reasonable angle with the swing trajectory of the roller mounting bracket 14. When the cylinder piston rod extends and retracts, the driving force can be efficiently converted into the swing torque of the roller mounting bracket 14 through the hinge point, which can directly drive the guide roller 2 to swing without additional transmission components, reducing power transmission loss.

[0043] Preferably, the swing telescopic cylinder 16 can be replaced with a servo telescopic electric cylinder.

[0044] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0045] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
