[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0020] The metal plate rolling device according to an embodiment of this application will now be described with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, the metal plate rolling device of this application embodiment may include a rolling device 10 and a driving device 20.

[0022] The curling device 10 may include a support platform 11, a cylinder 12, a support plate 13, a clamping assembly 14, a first curling component 15, a second curling component 16, and a first telescopic mechanism 17. The support platform 11 is mounted on a support base 101, the cylinder 12 is rotatably mounted on the support platform 11 via rotating components such as bearings, and the support plate 13 is slidably mounted inside the cylinder 12.

[0023] In the embodiments of this application, one end of the cylinder 12 is an open structure and the other end is a closed structure. The inner diameter of the cylinder 12 is equal to the outer diameter of the support plate 13. Multiple slides 121 are provided on the inner wall of the cylinder 12, and multiple sliders 131 are provided on the support plate 13. The multiple sliders 131 are slidably connected to the multiple slides 121 in a one-to-one correspondence. This structural design enables the support plate 13 to slide smoothly axially within the cylinder 12.

[0024] A clamping assembly 14 is disposed at the center of the support plate 13, and is used to clamp and fix one end of the metal plate to be bent. A first coiling member 15 is disposed around the clamping assembly 14 on the support plate 13, and one end of the first coiling member 15 is connected to the clamping assembly 14. A second coiling member 16 is disposed around the first coiling member 15 on one end wall of the cylinder 12, and the second coiling member 16 is slidably connected to the first coiling member 15.

[0025] It should be noted that the first coiling component 15 and the second coiling component 16 described in this embodiment together constitute a complete Archimedean spiral coiling plate, and the width of the second coiling component 16 is half the width of the first coiling component 15. Both the first coiling component 15 and the second coiling component 16 can be made of high-strength, wear-resistant metal materials, such as high-quality alloy steel, to ensure that they can withstand greater pressure and friction during the coiling process, thereby ensuring coiling accuracy and the service life of the equipment.

[0026] The first retractable mechanism 17 is disposed on the other end wall of the cylinder 12, and the output end of the first retractable mechanism 17 penetrates into the cylinder 12 and is connected to the support plate 13. The driving device 20 is disposed on the support base 101 and is connected to the cylinder 12. The driving device 20 is used to drive the cylinder 12 to rotate the support plate 13, the clamping assembly 14, the first coiling member 15, the second coiling member 16, and the first retractable mechanism 17. It should be noted that the first retractable mechanism 17 described in this embodiment can be a cylinder, a hydraulic cylinder, or an electric telescopic rod. The initial state of the output end of the first retractable mechanism 17 is the extended state.

[0027] Specifically, when it is necessary to curl the metal sheet to be processed, the relevant personnel can place one end of the metal sheet to be curled on the clamping assembly 14 for fixation. Then, the drive device 20 is started to drive the cylinder 12 to rotate the support plate 13, the clamping assembly 14, the first curling piece 15, the second curling piece 16 and the first telescopic mechanism 17. The metal sheet to be curled is first curled onto the first curling piece 15. After the metal sheet is completely wrapped around the first curling piece 15, the output end of the first telescopic mechanism 17 is retracted, and the clamping assembly 14 and the first curling piece 15 are moved toward the cylinder 12 by the support plate 13 until the metal sheet curled on the first curling piece 15 is completely located inside the second curling piece 16.

[0028] As the cylinder 12 continues to rotate, the metal plate coiled on the first coiling element 15 continues to coil onto the second coiling element 16, thus coiling the metal plate onto an Archimedean spiral-shaped coiling plate formed by the first and second coiling elements 15, thereby coiling it into the desired shape. This method allows for the coiling of metal plates of different specifications, meeting diverse production needs, and eliminates the need for cumbersome equipment adjustments, effectively reducing equipment waiting time and improving coiling efficiency.

[0029] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 1 , Figures 4-6 As shown, the clamping assembly 14 may include a support column 141, a pressure plate 142, multiple transmission mechanisms 143, and a second telescopic mechanism 144.

[0030] The support column 141 is vertically mounted on the support plate 13, and has a clamping opening 1401 for holding one end of the metal plate to be rolled. A mounting chamber 1402 parallel to the clamping opening 1401 is formed within the support column 141. Multiple equally spaced drive blocks 1403 are arranged side-by-side within the mounting chamber 1402. Multiple equally spaced mounting channels 1404 are formed within the support column 141, located between the clamping opening 1401 and the mounting chamber 1402. For example, there can be 2, 3, or 4 mounting channels 1404, and the specific number can be selected according to the actual situation, without limitation. The mounting channels 1404 communicate with both the mounting chamber 1402 and the clamping opening 1401.

[0031] The pressure plate 142 is movably and vertically disposed within the clamping opening 1401, and the pressure plate 142 is located within the clamping opening 1401 of the portion of the support column 141 extending out of the second coiled member 16.

[0032] Multiple transmission mechanisms 143 are respectively installed in the corresponding installation channels 1404, and one end of each transmission mechanism 143 is connected to the pressure plate 142, and the other end of each transmission mechanism 143 is respectively connected to the corresponding drive block 1403.

[0033] The second retractable mechanism 144 is disposed on the end wall of the support column 141 away from the support plate 13, and the output end of the second retractable mechanism 144 penetrates into the mounting chamber 1402 and is connected to a plurality of drive blocks 1403 respectively.

[0034] It should be noted that the second retractable mechanism 144 described in this embodiment can be a pneumatic cylinder or a hydraulic cylinder.

[0035] Furthermore, in one embodiment of this application, such as Figure 6 As shown, the transmission mechanism 143 may include a guide rod 1431, a collar 1432 and a first spring 1433. The guide rod 1431 is movably disposed in the mounting channel 1404, and one end of the guide rod 1431 is fixedly connected to the pressure plate 142, while the other end of the guide rod 1431 is in contact with the inclined surface of the drive block 1403.

[0036] The collar 1432 is sleeved and fixed on the guide rod 1431, and the collar 1432 is slidably connected to the mounting channel 1404. The first spring 1433 is sleeved on the guide rod 1431, and one end of the first spring 1433 is fixedly connected to the collar 1432, and the other end of the first spring 1433 is fixedly connected to the end wall of the mounting channel 1404 near the pressure plate 142.

[0037] Understandably, when it is necessary to clamp and fix one end of the metal plate to be rolled, the worker can place one end of the metal plate to be rolled into the clamping port 1401 opened on the support column 141 and activate the second telescopic mechanism 144. The output end of the second telescopic mechanism 144 extends, pushing multiple drive blocks 1403 in the mounting chamber 1402 to move. Since the drive block 1403 abuts against the guide rod 1431 in the transmission mechanism 143, the movement of the drive block 1403 will cause the guide rod 1431 to slide in the mounting channel 1404. The guide rod 1431 drives the pressure plate 142 to move downward, and at the same time drives the collar 1432 to compress the first spring 1433, thereby tightly clamping one end of the metal plate between the pressure plate 142 and the support column 141, ensuring that the metal plate will not shift during the rolling process.

[0038] Furthermore, in one embodiment of this application, such as Figure 1As shown, the drive device 20 may include an external gear ring 21, a drive mechanism 22, and a gear 23, wherein the external gear ring 21 is tightly fitted and welded to the cylinder 12. The drive mechanism 22 is mounted on the support base 101, and the output end of the drive mechanism 22 is connected to the gear 23, wherein the gear 23 meshes with the external gear ring 21.

[0039] It should be noted that the drive mechanism 22 described in this embodiment may be a servo motor.

[0040] Understandably, by activating the drive mechanism 22 of the drive device 20, the drive mechanism 22 drives the gear 23 to rotate, and the gear 23 meshes with the external gear ring 21, causing the cylinder 12 to begin rotating. As the cylinder 12 rotates, the first coiling member 15 and the second coiling member 16 also rotate, beginning to coil the metal plate. The metal plate first winds around the first coiling member 15. After the metal plate is completely wound around the first coiling member 15, the first retractable mechanism 17 is activated, its output end retracts, driving the support plate 13 to move axially within the cylinder 12, causing the metal plate wound around the first coiling member 15 to gradually enter the second coiling member 16. The cylinder 12 continues to rotate, and the metal plate is further coiled on the second coiling member 16, finally coiled into the desired shape.

[0041] Furthermore, in one embodiment of this application, such as Figure 1 and Figure 2 As shown, the metal plate rolling equipment may also include an auxiliary rolling device 30 arranged side by side with the rolling device 10. The auxiliary rolling device 30 may include two columns 31, a U-shaped frame 32, a support 33, a third telescopic mechanism 34, and two auxiliary conveying mechanisms 35.

[0042] Two uprights 31 are fixedly mounted side-by-side and vertically on the support base 101. A U-shaped frame 32 is positioned above the two uprights 31, with one end of the U-shaped frame 32 integrally connected to the upright 31 near the support platform 11 to ensure the integrity and stability of the structure. A support bracket 33 is movably mounted within the U-shaped frame 32.

[0043] The third telescopic mechanism 34 is mounted on the U-shaped frame 32, and its output end is fixedly connected to the support 33. The third telescopic mechanism 34 may be a hydraulic telescopic rod to provide stable lifting power. Two auxiliary conveying mechanisms 35 are arranged side by side, with one auxiliary conveying mechanism 35 rotatably mounted between the two columns 31 and the other auxiliary conveying mechanism 35 rotatably mounted on the support 33.

[0044] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 2As shown, the auxiliary conveying mechanism 35 may include a spline shaft 351, a spline sleeve 352, and a second spring 353. The spline shaft 351 can be rotatably mounted via a bearing. The spline sleeve 352 is sleeved on the spline shaft 351, and the two ends of the spline sleeve 352 are respectively provided with a first retaining ring 3501. The end of the spline shaft 351 near the support platform 11 is provided with a second retaining ring 3502.

[0045] The second spring 353 is sleeved on the spline shaft 351, and one end of the second spring 353 is fixedly connected to the second retaining ring 3502, and the other end is fixedly connected to the first retaining ring 3501 near the second retaining ring 3502.

[0046] Understandably, the second spring 353 enables the spline sleeve 352 to move axially within a certain range, adapting to the positional changes of the metal plate during the rolling process. This provides auxiliary support and conveying for the metal plate, preventing it from shifting or deforming during the rolling process and ensuring the accuracy and quality of the rolling.

[0047] Specifically, when the metal sheet to be rolled needs to be rolled, the operator can pass one end of the metal sheet through the two splined sleeves 352 and place it in the clamping opening 1401 on the support column 141 for fixation. Then, the height of the bracket 33 is adjusted according to the actual situation of the metal sheet. That is, by activating the third telescopic mechanism 34, the output end of the third telescopic mechanism 34 extends and pushes the bracket 33 to drive the auxiliary conveying mechanism 35 located above the metal sheet to move downward, so that the splined sleeves 352 in the two auxiliary conveying mechanisms 35 can maintain good contact with the metal sheet, while ensuring that one edge of the metal sheet contacts the first retaining ring 3501 near the support table 11 to limit the conveying of the metal sheet.

[0048] After the metal plate is completely wound around the first coiled part 15, the output end of the first telescopic mechanism 17 retracts, causing the support plate 13 to move axially within the cylinder 12, thus moving the metal plate wound around the first coiled part 15 into the second coiled part 16. During this process, the moving metal plate causes the spline sleeve 352 to move and compress the second spring 353, so that the spline sleeve 352 plays an auxiliary support and limiting transmission role throughout the entire coiling process of the metal plate.

[0049] Once one end of the metal plate is rolled up, the drive mechanism 22 can be stopped first, causing the cylinder 12 to stop rotating. Then, the second telescopic mechanism 144 is controlled to retract its output end, causing the pressure plate 142 to rise and release the clamping of the metal plate. Next, the third telescopic mechanism 34 is controlled to retract its output end, and through the bracket 33, the auxiliary conveying mechanism 35 located above the metal plate is raised, thereby releasing the restriction on the metal plate itself.

[0050] Finally, remove the rolled metal sheet from the equipment to complete the entire rolling operation.

[0051] In summary, the metal plate rolling equipment of this application embodiment can meet the rolling tasks of various metal plates of different specifications, and does not require cumbersome equipment adjustments, effectively reducing equipment waiting time and improving rolling efficiency.
