Description

Technical Field

[0001] The utility model relates to the technical field of leveling machines, in particular to a precision leveling machine for metal plates. Background Art

[0002] Precision sheet metal levelers are crucial equipment in the metalworking industry, primarily used for high-precision leveling of sheet metal, ensuring that it meets the flatness requirements of subsequent processing. In the modern metalworking industry, as demands for sheet metal quality continue to rise, precision levelers are widely used due to their ability to effectively improve sheet metal flatness and enhance product quality stability.

[0003] Traditional sheet metal levelers typically consist of a drive motor, a transmission, and a set of leveling rollers spaced at a fixed interval. During operation, a sheet metal is fed from the feed end between the leveling rollers. The drive motor, through the transmission, drives the rollers, which compress and stretch the sheet metal using pressure and friction between the rollers, gradually eliminating any bending or deformation. Throughout this process, the sheet metal is primarily driven between the rollers by the force of the feed device.

[0004] However, traditional sheet metal levelers have certain defects during actual use. During the movement of the sheet metal, when affected by external factors such as collisions or vibrations, the sheet metal is prone to positional displacement. This positional displacement not only causes uneven force on the sheet metal during the leveling process, affecting the correction effect and making the leveled sheet metal unable to meet high-precision flatness requirements, but also causes friction or collision between the sheet metal and the internal components of the leveler, damaging the equipment, increasing equipment maintenance costs and downtime, and seriously restricting the production efficiency and product quality improvement of metal processing equipment. Therefore, a sheet metal precision leveler is proposed to solve the above problems. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a metal sheet precision leveling machine, comprising a base plate 1, a working chamber 2 fixedly connected to the top of the base plate 1, leveling cylinders 21 are provided on both sides of the working chamber 2, and an adjustment component is provided on the outer wall of the leveling cylinder 21, and roller conveyor belts 3 are provided on both sides of the leveling cylinder 21, and each roller conveyor belt 3 is fixedly connected to a fixed base 4 at the bottom, and the bottom of the fixed base 4 is fixedly connected to the top of the base plate 1, and a limit component is provided on the outer wall of the roller conveyor belt 3 on one side;

[0035] The limiting assembly includes multiple limiting cylinders 9, which are located on the outer wall of the roller conveyor belt 3 on one side. The limiting cylinder 9 is a cylindrical structure and is mainly used to block and limit the items on the conveyor belt at a specific position to prevent the items from excessively shifting. An electric telescopic rod 5 is fixedly connected to the inside of the fixed base 4 on one side, and a slide 6 is fixedly connected to the output end of the electric telescopic rod 5. The slide 6 is slidably connected to the inside of the roller conveyor belt 3 on one side. The slide 6 is a flat structure and can slide smoothly inside the roller conveyor belt 3 under the push of the electric telescopic rod 5. A plurality of beveled chutes 7 are provided inside the slide 6. The beveled chutes 7 are at a certain inclination angle and are used to cooperate with the connecting shaft 8 to change the position of the connecting shaft 8. A plurality of fixed brackets 10 are fixedly connected to the top of the roller conveyor belt 3 on one side. The fixed bracket 10 plays a supporting and fixing role. A linear chute 11 is provided on both sides of the interior of each fixed bracket 10. The linear chute 11 is a linear groove that provides a guide for the sliding of the connecting shaft 8. A connecting shaft 8 is rotatably connected to the interior of each limiting cylinder 9. The connecting shaft 8 can rotate flexibly in the limiting cylinder 9. One end of each connecting shaft 8 is slidably connected to the inner wall of the linear chute 11, and the other end of each connecting shaft 8 is slidably connected to the inner wall of the beveled chute 7;

[0036] Specifically, during the use of the equipment, the metal plate is first placed on the top of the roller conveyor belt 3, and the metal plate is smoothly introduced into the interior of the working chamber 2. To ensure the stability and accuracy of the metal plate in the subsequent processing process, the electric telescopic rod 5 is started next. The function of the electric telescopic rod 5 is to drive the slide plate 6 to slide along the inside of the roller conveyor belt 3 through its output end. The movement of the slide plate 6 can accurately control the position of the metal plate during the transportation process. In this process, the angled slide groove 7 guides the connecting shaft 8 to slide smoothly on the inner wall of the straight slide groove 11. As the connecting shaft 8 slides, the two sides of the metal plate will be evenly driven to move to the opposite side. Once the sliding of the connecting shaft 8 is completed, the limit cylinder 9 will automatically move to the two sides of the metal plate with the movement of the slide groove structure, forming a physical limit for the metal plate. This limit can effectively prevent the metal plate from positionally offset during movement.

[0037] Reference Figure 2 、 Figure 4 and Figure 5The adjustment assembly includes a plurality of connecting rings 25, which are located on both sides of each leveling cylinder 21. The connecting rings 25 are annular metal structures, and their function is to connect related components and transmit power to achieve the adjustment of the leveling cylinder 21. The inside of the working chamber 2 is fixedly connected to the fixed bracket 2 12 on both sides, and each fixed bracket 2 12 is fixedly connected to a motor 24 on one side. The output end of each motor 24 is fixedly connected to the connecting shaft 2 13, which is a metal round shaft that can effectively transmit the power of the motor 24 and can be fixed on the fixed bracket 2 12. The inner portion is flexibly rotated, and a plurality of linear slide grooves 22 are provided on both sides of each connecting shaft 213. The linear slide grooves 22 are straight grooves for guiding the slider 23 on the connecting ring 25 to slide to adjust the position. The outer wall of each fixed bracket 212 is fixedly connected to a two-way cylinder 15. The output ends on both sides of each two-way cylinder 15 are fixedly connected to a connecting block 16. The connecting block 16 plays a connecting transition role. The outer wall of each connecting block 16 is fixedly connected to a connecting block 217 and a support frame 18. The connecting block 217 and the support frame 18 are fixedly connected. The two connecting blocks 17 are vertically fitted together, and the support frame 18 provides stable support for the whole. Each connecting block 217 is rotatably connected to the outer wall of the connecting ring 25 to ensure that the connecting ring 25 can rotate flexibly. The inner wall of each connecting ring 25 is fixedly connected with a plurality of sliders 23. The sliders 23 fit with the inner wall of the linear slide 22 to achieve the linear displacement of the connecting ring 25 along the connecting shaft 213. One end of each connecting ring 25 is fixedly connected with a bevel gear 14. The inside of the bevel gear 14 fits with the outer wall of the connecting shaft 213. The bevel gear 14 is a conical tooth structure. The structure is used to change the direction of power transmission. A rotating shaft 20 is rotatably connected between the support frames 18 on both sides. The rotating shaft 20 is a metal circular shaft that can stably rotate and transmit power. Each rotating shaft 20 is fixedly connected to a bevel gear 2 19 at both ends. The bevel gear 2 19 is meshed with the bevel gear 1 14. The bevel gear 2 19 also has conical teeth. The power is transmitted to the rotating shaft 20 through meshing to drive the leveling cylinder 21 to rotate and adjust. Each rotating shaft 20 is rotatably connected to the inside of the leveling cylinder 21, so that the leveling cylinder 21 can rotate under the drive of the rotating shaft 20 to achieve material leveling.

[0038] Specifically, when the metal plate moves to one side of the leveling cylinder 21, the motor 24 is started, and the motor 24 drives the connecting shaft 2 13 to rotate through its output end. The rotational movement of the connecting shaft 2 13 further drives the bevel gear 1 14 to rotate through the connecting ring 25. The motive force brought by the rotation of the bevel gear 14 will be transmitted to the surface of the bevel gear 2 19, so that the rotating shaft 20 rotates synchronously on the outer wall of the leveling cylinder 21. Through this series of power transmission, the leveling cylinder 21 obtains rotational movement, thereby generating an extrusion effect, uniformly correcting and flattening the surface of the metal plate. Since the metal plate will deform during the processing, the rotation of the leveling cylinder 21 can effectively eliminate these deformations, making the surface of the metal plate tend to be flat, ensuring that its quality meets the required standards. In addition, when the thickness of the metal plate changes, the equipment can automatically adapt and adjust. When the thickness of the metal plate is larger or smaller, in order to ensure the accuracy and effect of the leveling process, the system starts the two-way cylinder 15, and the two-way cylinder 15 drives the connecting shaft 2 1 through the output ends on both sides. The connecting block 21 and the support frame 18 on the outer wall move synchronously. During the movement, the connecting block 21 drives the slider 23 to slide on the inner wall of the linear slide groove 22 through the connecting ring 25, ensuring that the rotational movement of the bevel gear 14 is not affected during the equipment adjustment process, thereby ensuring the stability and efficiency of the leveling device. The movement of the support frame 18 can not only adjust the position of the connecting block 21, but also drive the leveling cylinder 21 and the bevel gear 2 19 to move synchronously through the rotating shaft 20, so as to ensure that the leveling cylinder 21 rotates while adjusting the distance between the leveling cylinders 21 on both sides to adapt to metal plates of different thicknesses. When the metal plate is thicker, the equipment automatically increases the distance between the leveling cylinders 21 to avoid applying excessive extrusion force and preventing damage to the metal plate; when the metal plate is thinner, the distance between the leveling cylinders 21 will be appropriately reduced, ensuring the consistency and accuracy of the correction effect, improving the adaptability of the equipment, avoiding the tedious process of stopping the equipment and manually adjusting the equipment spacing when the thickness of the metal plate changes, and improving the operation efficiency of the production line.

[0039] Working principle: During the use of the equipment, the metal plate is placed on the top of the roller conveyor belt 3 and guided into the interior of the working chamber 2. During this process, the electric telescopic rod 5 is started, and the output end of the electric telescopic rod 5 is used to drive the slide plate 6 to slide inside the roller conveyor belt 3, and the angled slide 7 is used to drive the connecting shaft 18 to slide on the inner wall of the linear slide 11, so that the connecting shafts 18 on both sides move to the opposite side until the limiting cylinder 9 is moved to both sides of the metal plate, thereby limiting the movement of the metal plate and avoiding position deviation during the movement, which leads to unsatisfactory subsequent correction effects. When the metal plate moves to one side of the leveling cylinder 21, the motor 24 is started at this time, and the output end of the motor 24 is used to drive the connecting shaft 2 13 to rotate, and the bevel gear 14 is synchronously driven to rotate through the connecting ring 25. The rotational force of the bevel gear 14 will be transmitted to the surface of the bevel gear 2 19, thereby driving the rotating shaft 20 on the outer wall of the leveling cylinder 21 The rotation movement is performed synchronously, and the rotation of the leveling cylinder 21 is used to extrude and correct the surface of the metal plate to ensure that the surface of the metal plate tends to be flat. When the thickness of the metal plate is large or small, the two-way cylinder 15 is started, and the output ends on both sides of the two-way cylinder 15 are used to drive the connecting block 217 and the support frame 18 on the outer wall of the connecting shaft 213 to move synchronously. During the movement, the connecting block 21 will drive the slider 23 to slide on the inner wall of the linear slide groove 22 through the connecting ring 25. This can adjust the position of the bevel gear 14 without affecting its rotation movement. During the movement of the support frame 18, the leveling cylinder 21 and the bevel gear 2 19 will be driven to move synchronously through the rotating shaft 20. By ensuring that the leveling cylinder 21 rotates while adjusting the distance between the leveling cylinders 21 on both sides, the thickness of different metal plates can be matched, avoiding the need to stop the equipment and adjust the distance between the leveling cylinders 21 on both sides when the thickness of the metal plate is too large or too small, thereby improving the applicability and work efficiency of the equipment.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
