Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, and in particular to a device for rolling a cone body on a plate rolling machine. Background Technology
[0002] Plate rolling machines are the core equipment for rolling and forming sheet metal, and are widely used in industries such as pressure vessels, pipe manufacturing, and aerospace.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: When traditional plate rolling machines roll conical workpieces, they rely on manual adjustment of the support structure. Faced with the complex characteristics of cone diameter change and generatrix tilt, it is difficult to accurately control the force on the plate, which can easily lead to local deformation, wrinkles, and generatrix bending, and cannot meet the requirements for high-precision cones. Manual adjustment of support position and pressure is repeated, which relies on experience and takes a long time. In small-batch, multi-variety production, the rhythm is disordered, and fatigue and errors can easily cause the lead screw to jam. Utility Model Content
[0004] The technical problem to be solved by this utility model is that in the existing technology, when rolling cones with traditional plate rolling machines, the support structure is manually adjusted. Due to the geometric characteristics of the cone workpiece, such as variable diameter and inclined generatrix, manual adjustment is difficult to accurately control the stress balance of each area of the plate, which easily leads to the defects of local deformation, wrinkles and non-straight generatrix of the plate. Therefore, we propose a plate rolling cone rolling device.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0016] Reference Figures 1-5 As shown, this utility model provides a technical solution: a plate rolling machine cone rolling device, including a plate rolling machine body 1, a fixing plate 2 fixedly connected to one side of the plate rolling machine body 1, a first servo motor 3 fixedly connected to the surface of the fixing plate 2, a first lead screw 4 fixedly connected to the output end of the first servo motor 3, a first threaded cylinder 5 threadedly connected to the arc surface of the first lead screw 4, and a support plate 19 fixedly connected to one end of the first threaded cylinder 5. The first servo motor 3 drives the first lead screw 4 to achieve 19 mm-level adjustment of the support plate, automatically adapting to cones of different specifications. The support adjustment time is short, the equipment failure rate is reduced, and production problems caused by frequent adjustments are avoided. To mitigate the delay, a mounting plate 8 is fixedly connected to the other side of the plate rolling machine body 1. A second servo motor 9 is fixedly connected to one side of the mounting plate 8. A second lead screw 10 is fixedly connected to the output end of the second servo motor 9. A second threaded cylinder 11 is threadedly connected to the arc surface of the second lead screw 10. A connecting frame 12 is fixedly connected to one end of the second threaded cylinder 11. Several conveying cylinders 13 are fixedly connected to the inner surface of the connecting frame 12. The second servo motor 9 drives the second lead screw 10 to rotate, causing the conveying cylinders 13 to move linearly. This synchronizes the plate feeding speed with the plate rolling machine's processing rollers, avoiding material discharge jams and uneven tension caused by manual unloading, and reducing plate wrinkles. The support plate 19 has a protective pad 15 fixedly connected to its surface. The protective pad 15 buffers the contact stress between the support plate 19 and the plate, preventing scratches and indentations caused by direct metal contact. A semi-circular plate 6 is fixedly connected to one side of the fixing plate 2. A limiting rod 7 is slidably inserted into the semi-circular plate 6. One end of the limiting rod 7 is fixedly connected to the support plate 19. The limiting rod 7 slides within the semi-circular plate 6, limiting the radial sway of the support plate 19 and ensuring that it only moves along the axial direction of the lead screw when under stress, thus improving support accuracy. A sliding rod 14 is slidably inserted into the mounting plate 8. One end of the sliding rod 14 is fixedly connected to the connecting frame 12. The sliding rod 14 slides in conjunction with the mounting plate 8 to ensure... When the connecting frame 12 drives the conveyor cylinder 13 to move linearly, there is no deviation, and it forms a double constraint guide with the second lead screw 10. Several connecting seats 16 are fixedly connected to the inner surface of the plate rolling machine body 1. Two setting frames 17 are fixedly connected to the surface of the connecting seats 16. Rollers 18 are fixedly connected to the surface of the setting frames 17. The rollers 18 are located below the processing roller of the plate rolling machine body 1. The rollers 18 share part of the rolling pressure, reduce the bending deformation of the processing roller, extend the service life of the processing roller, and reduce energy consumption. The arc surface of the conveyor cylinder 13 is covered with a protective sleeve. The protective sleeve provides flexible contact and avoids scratches and dents caused by hard friction between the conveyor cylinder 13 and the plate.
[0017] Working principle: The plate rolling machine body 1 serves as the core processing carrier. On one side, the first servo motor 3 drives the first lead screw 4 to rotate, causing the first threaded cylinder 5 to move the support plate 19 precisely along the axial direction. Combined with the radial constraint of the semi-circular plate 6 and the limiting rod 7, this ensures that the support plate 19 moves stably only along the direction of the lead screw, quickly adapting to the support requirements of different sized cones and reducing the time spent on manual adjustments and the risk of failure. On the other side, the second servo motor 9 drives the second lead screw 10, which, in conjunction with the double constraint guidance of the slide rod 14 and the mounting plate 8, causes the second threaded cylinder 11 to drive the connecting... The frame 12 and the conveyor cylinder 13 move linearly to synchronize the feeding speed of the sheet metal with the processing roller, avoiding material jamming and uneven tension, and reducing wrinkle defects. During the rolling process, the protective pad 15 on the surface of the support plate 19 and the protective sleeve of the conveyor cylinder 13 form flexible contact to prevent scratches and indentations on the sheet metal surface. The roller 18 on the connecting seat 16 is located below the processing roller and works with the support plate 19 and the conveyor cylinder 13 to share the rolling pressure, reduce the deformation of the processing roller, reduce energy consumption, and ensure the straightness and taper accuracy of the cone generatrix, ultimately achieving efficient and stable cone rolling.
[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
