Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, and in particular to a plate rolling machine that facilitates adjustment of the roller spacing. Background Technology

[0002] In the field of sheet metal processing, plate rolling machines achieve the bending and forming of sheet metal through the extrusion and transmission between rolling rollers. The precise adjustment of the roller spacing is the core link to adapt to sheet metal of different thicknesses and ensure rolling accuracy. However, the traditional roller spacing adjustment method of plate rolling machines has significant defects, which seriously restricts processing efficiency and forming quality.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Traditional roller spacing adjustment mostly relies on manual cranks or hydraulic cylinders to move the rollers. Manual adjustment has poor precision, and hydraulic adjustment is easily affected by oil pressure fluctuations. For high-precision rolling requirements, spacing deviations can lead to uneven stress on the sheet material, resulting in defects such as excessive straightness and surface indentations after rolling, with a defect rate exceeding 15%, increasing rework costs. When changing to sheets of different thicknesses, traditional adjustment methods require multiple trial and error adjustments, with each adjustment taking more than 15 minutes. For multi-variety, small-batch production, traditional structures cannot achieve stepless adjustment of the roller spacing, only adapting to a limited number of preset thicknesses, and cannot meet personalized processing needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of low adjustment accuracy, resulting in large product curvature deviation and surface scratches.

Detailed Implementation

[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 1-4As shown, this utility model provides a technical solution: a plate rolling machine that facilitates adjustment of the roller spacing, including a fixed frame 1, two fixed rollers 2 mounted on the inner surface of the fixed frame 1, two setting frames 3 fixedly connected to the surface of the fixed frame 1, a servo motor 4 fixedly connected to one side of the setting frame 3, a lead screw 5 fixedly connected to the output end of the servo motor 4, a threaded cylinder 6 threadedly connected to the arc surface of the lead screw 5, a connecting block 7 fixedly connected to one end of the threaded cylinder 6, a retaining ring 8 fixedly connected to one side of the connecting block 7, a connecting shaft 9 rotatably connected to the inner surface of the retaining ring 8, and a moving roller 10 fixedly connected to one end of the two connecting shafts 9 that are close to each other. The moving roller 10 is moved by the transmission method of the servo motor 4 driving the lead screw 5 and the threaded cylinder 6. The precise movement of the rollers and the accuracy of the roller spacing adjustment meet the requirements of high-precision rolling, effectively ensuring the quality of the rolled sheet and reducing rolling errors. A limit groove 11 is formed on the inner surface of the frame 3, and a limit plate 12 is slidably connected to the inner wall of the limit groove 11. One side of the limit plate 12 is fixedly connected to the connecting block 7. The sliding fit between the limit plate 12 and the limit groove 11 restricts the radial sway of the connecting block 7 during movement, ensuring that the connecting block 7 moves stably only along the axial direction of the lead screw 5, thereby ensuring the precise adjustment trajectory of the moving roller 10. Two support plates 13 are fixedly connected to the bottom of the fixed frame 1. An adjustment chamber 14 is slidably connected to the arc surface of the support plate 13. Sliding holes are formed on both sides of the adjustment chamber 14. A slide frame 15 is slidably connected to the inner wall of the sliding hole. A threaded rod 16 is threadedly inserted into the slide frame 15. Several threaded grooves 17 are opened on both sides of the adjustment chamber 14. The threaded rod 16 is threadedly connected to the inner wall of the threaded groove 17. The adjustment chamber 14 can slide along the support plate 13 to adjust the overall support width of the equipment and adapt to the width requirements of different work sites. A groove is opened on the inner surface of the retaining ring 8. Several balls 20 are installed on the inner wall of the groove of the retaining ring 8. The balls 20 convert the sliding friction between the connecting shaft 9 and the retaining ring 8 into rolling friction, making the connecting shaft 9 rotate more smoothly and reducing the resistance when the moving roller 10 rotates. A handle 18 is fixedly connected to one end of the threaded rod 16. The handle 18 increases the grip arm of the hand, so that the threaded rod 16 can rotate. The operation is labor-saving; a single person can complete the fixing and adjustment of the adjustment chamber 14 without the need for tools. The positioning function of the handle 18 improves the alignment accuracy of the threaded rod 16 and the threaded groove 17, shortening the operation time. A rectangular plate 19 is fixedly connected to one side of the adjustment chamber 14. The bottom of the rectangular plate 19 has an anti-slip groove, which increases the contact area between the adjustment chamber 14 and the ground. Together with the bottom anti-slip groove, it effectively prevents the equipment from shifting due to vibration during the rolling process. The size of the slide 15 is matched with the size of the sliding hole of the adjustment chamber 14. The precise fit between the slide 15 and the sliding hole limits the lateral displacement of the slide 15 during movement, ensuring that the threaded rod 16 can be accurately aligned with the threaded groove 17, avoiding adjustment jamming caused by misalignment.

[0017] Working Principle: When the plate rolling machine is working, the fixed frame 1 provides basic support for the entire equipment. The two fixed rollers 2 installed inside it serve as the rolling reference. When it is necessary to adjust the roller spacing to accommodate plates of different thicknesses, the servo motor 4 on one side of the frame 3 is activated, driving the lead screw 5 to rotate. Since the lead screw 5 is threadedly connected to the threaded cylinder 6, the rotational motion of the lead screw 5 is converted into the linear motion of the threaded cylinder 6, which in turn drives the connecting block 7, the retaining ring 8, the connecting shaft 9, and the moving roller 10 to move synchronously, thereby realizing the adjustment of the spacing between the moving roller 10 and the fixed roller 2. With the help of the servo motor 4 driving the lead screw 5 and the threaded cylinder 6, the moving roller 10 can be adjusted. The precise movement of the connecting block 7 ensures the accuracy of the roller spacing adjustment, meets the requirements of high-precision rolling, effectively reduces rolling errors, and guarantees the quality of the rolled sheet. During the movement of the connecting block 7, the sliding fit between the limiting groove 11 on the inner surface of the frame 3 and the limiting plate 12 restricts the radial sway of the connecting block 7, ensuring that the connecting block 7 moves stably only along the axial direction of the lead screw 5. This ensures the accuracy of the adjustment trajectory of the moving roller 10 and further improves the accuracy of the roller spacing adjustment. The ball bearings 20 in the groove on the inner surface of the retaining ring 8 convert the sliding friction between the connecting shaft 9 and the retaining ring 8 into rolling friction, making the rotation of the connecting shaft 9 smoother and reducing the resistance when the moving roller 10 rotates, ensuring the smooth movement of the connecting block 7. The moving roller 10 rotates flexibly during the winding process, improving winding efficiency. For the support and fixation of the equipment, the support plate 13 at the bottom of the fixing frame 1 provides a sliding track for the adjusting chamber 14. The adjusting chamber 14 slides along the support plate 13 to adjust the overall support width of the equipment to adapt to the width requirements of different work sites. The slide 15 slides in the sliding hole of the adjusting chamber 14. When the adjusting chamber 14 is adjusted to the appropriate position, the position of the adjusting chamber 14 can be locked by the threaded rod 16 in the slide 15 and the threaded grooves 17 on both sides of the adjusting chamber 14. The handle 18 at one end of the threaded rod 16 increases the hand grip lever, making operation easier and allowing a single person to complete the fixing. The adjustment and positioning function of the handle 18 improve the alignment accuracy of the threaded rod 16 and the threaded groove 17, shortening the operation time. At the same time, the size of the slide 15 is adapted to the size of the sliding hole of the adjustment chamber 14, limiting the lateral offset of the slide 15 when it moves, ensuring that the threaded rod 16 can be accurately aligned with the threaded groove 17, avoiding adjustment jamming caused by misalignment. In addition, the rectangular plate 19 on one side of the adjustment chamber 14 increases the contact area with the ground, and together with the anti-slip groove at its bottom, it effectively enhances the friction between the equipment and the ground, preventing the equipment from shifting due to vibration during the rolling process, ensuring the overall stability of the equipment, and providing a reliable guarantee for accurate 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.
