Description

Technical Field

[0001] This utility model relates to the field of surface treatment device technology, and in particular to a surface treatment device for metal sheets. Background Technology

[0002] In the field of sheet metal processing, surface polishing is a key process for improving product appearance and performance. However, traditional polishing equipment generally uses single-sided sequential processing or fixed-gap roller groups, resulting in cumbersome operation procedures and poor adaptability. For example, after polishing one side, manual flipping is required, which not only increases labor costs but also reduces overall efficiency. Fixed-gap polishing roller groups are difficult to adapt to sheets of different thicknesses, and forced processing can easily lead to uneven polishing or equipment damage. Furthermore, existing equipment often relies on complex parameter control systems to adjust the roller spacing, further increasing equipment costs and maintenance complexity. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a metal sheet surface treatment device that has the advantages of simultaneously treating both ends of metal sheets and flexibly adapting to sheets of various thicknesses, thus solving some of the problems mentioned in the background technology.

[0004] This utility model provides the following technical solution: a surface treatment device for metal sheets, comprising a lifting plate and a U-shaped frame. Positioning rods are fixedly installed at the lower end of the lifting plate on both the left and right sides. Long swing rods and semi-swing rods are rotatably installed on each positioning rod. Polishing rollers are rotatably installed between the long swing rods and semi-swing rods. A bevel gear is fixedly sleeved through the long swing rod at the far end of each polishing roller. Positioning plates are fixedly installed near the upper side of each long swing rod. Drive motors are fixedly installed on each positioning plate. The output shafts of the drive motors pass through the positioning plates and are fixedly sleeved with bevel gears. Bevel gears mesh with bevel gears. Two sets of alignment plates are symmetrically installed at the middle of the upper surface of the U-shaped frame. The center lines of the two sets of alignment plates and the polishing rollers are on the same vertical plane.

[0005] Furthermore, bearing seats are fixedly installed on the long swing arm near the lower side, and the output shaft of the drive motor passes through and is fixedly connected to the inner ring of the bearing seat. The lifting plate is provided with through slots near the left and right sides, and the upper end of the long swing arm passes through and is slidably connected to the inside of the through slot. These structural designs ensure that the drive motor can move synchronously with the polishing roller and other structures, avoiding structural conflicts and transmission misalignment.

[0006] Furthermore, a U-shaped frame is fixedly installed at the middle of the upper end of the lifting plate. The U-shaped frame passes through and is slidably connected inside the U-shaped frame. A hydraulic cylinder is fixedly installed at the middle of the upper end of the U-shaped frame. The lower telescopic end of the hydraulic cylinder is fixedly connected to the U-shaped frame. Guide rods are fixedly connected at all four corners of the lifting plate. The upper ends of the guide rods pass through and are slidably connected inside the U-shaped frame. The guide rods limit the movement of the lifting plate, thereby improving structural stability and uniform force distribution.

[0007] Furthermore, rockers are rotatably mounted on both sides of the alignment plates at their opposite ends. Each rocker has a limiting rod fixedly mounted on its opposite end. Four sets of slide rails are arranged in a matrix on the upper surface of the C-shaped frame. The lower end of each limiting rod passes through and slides inside the slide rail. That is, when the alignment plates are subjected to the pressure of the metal sheet, the rockers will drive the limiting rods to slide within the slide rails. This, combined with the sliding of the fixed rods, achieves the effect of limiting and preventing tilting.

[0008] Furthermore, each of the alignment plates is fixedly connected to a fixing rod at the middle of its farthest ends. The upper end of the platform of the C-shaped frame is fixedly installed with a fixing block near the middle of both the front and rear sides. The fixing rod passes through and is slidably connected inside the fixing block. A return spring is installed on the outside of the fixing rod between the fixing block and the alignment plate. That is, the rebound effect of the return spring is used to achieve adaptive clamping and centering positioning, which is simple and practical.

[0009] The advantages of this utility model are as follows:

[0010] 1. This device achieves synchronous polishing of the front and rear ends of metal sheets through the symmetrical swing-type adaptive structure design of the polishing roller. During the processing, the polishing roller automatically adjusts the spacing and fits the surface according to the thickness of the sheet, eliminating the need for manual flipping or repeated clamping, thus shortening the processing time, effectively increasing production capacity and reducing labor costs.

[0011] 2. This device adopts a mechanical adaptive structure to replace the traditional complex parameter control system. The polishing roller naturally fits the plate of different thicknesses through gravity and the guiding mechanism, avoiding equipment wear and precision reduction caused by frequent spacing adjustments. This design not only simplifies the operation process, but also enhances the equipment's compatibility with multiple specifications of plates, reduces the production preparation cycle and equipment maintenance costs, and combines practicality and economy.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 A surface treatment device for metal sheets includes a lifting plate 1 and a U-shaped frame 2. Positioning rods 3 are fixedly installed at the lower end of the lifting plate 1 on both sides at the middle. Long swing rods 4 and semi-swing rods 5 are rotatably installed on the positioning rods 3. Polishing rollers 6 are rotatably installed between the long swing rods 4 and semi-swing rods 5. The ends of the polishing rollers 6 that are furthest apart pass through the long swing rods 4 and are fixedly sleeved with bevel gears 7. Positioning plates 8 are fixedly installed on the long swing rods 4 near the upper side. Drive motors 9 are fixedly installed on the positioning plates 8. The output shafts of the drive motors 9 pass through the positioning plates 8 and are fixedly sleeved with bevel gears 10. The bevel gears 10 and 10 mesh with each other. Two sets of alignment plates 16 are symmetrically installed at the middle of the upper end of the U-shaped frame 2. The two sets of alignment plates 16 are on the same vertical plane as the center line of the polishing rollers 6. Turning on the drive motors 9 allows the bevel gears 10 to drive the bevel gears 7 to rotate. The device is powered by a bevel gear 7, which rotates the polishing roller 6. When the polishing roller 6 descends and contacts the metal sheet, it automatically separates on both sides and, under the influence of gravity, naturally comes into contact with the front and rear ends of the metal sheet, thus simultaneously polishing both ends. Compared to some existing equipment for surface polishing of metal sheets, this device can polish both ends of the metal sheet at the same time, eliminating the need for flipping and greatly improving processing efficiency. Furthermore, the symmetrically designed, swingable polishing roller 6 structure allows for natural contact between the polishing roller 6 and the surface of the metal sheet, eliminating the need for complex parameter control. This further improves processing efficiency and reduces the production and operating costs of the equipment. Within a certain range, it enables factories to quickly perform polishing operations on the surfaces of metal sheets of different thicknesses, making it not only practical and convenient but also flexible in use.

[0018] Please see Figures 1-2 Bearing seats 11 are fixedly installed on the long swing arm 4 near the lower side. The output shaft of the drive motor 9 passes through and is fixedly connected to the inner ring of the bearing seat 11. The lifting plate 1 is provided with through slots 12 near the left and right sides. The upper end of the long swing arm 4 passes through and is slidably connected to the inside of the through slot 12, ensuring the rationality of the structural design of this device. A U-shaped frame 13 is fixedly installed at the middle of the upper end of the lifting plate 1. The U-shaped frame 13 passes through and is slidably connected to the inside of the C-shaped frame 2. A hydraulic cylinder 14 is fixedly installed at the middle of the upper end of the U-shaped frame 13. The lower telescopic end of the hydraulic cylinder 14 is fixedly connected to the C-shaped frame 2. Guide rods 15 are fixedly connected at the four corners of the lifting plate 1. The upper end of the guide rods 15 passes through and is slidably connected to the inside of the C-shaped frame 2. By opening the hydraulic cylinder 14, its telescopic end can be retracted, thereby causing the U-shaped frame 13 to descend, which can ultimately drive the polishing roller 6 to descend.

[0019] Please see Figure 1 A rocker arm 17 is rotatably mounted on both sides of the opposite end of the alignment plates 16. A limit rod 18 is fixedly mounted on the rocker arm 17 at the end away from the alignment plate 16. Four sets of slide rails 19 are installed in a matrix on the upper part of the table of the C-shaped frame 2. The lower end of the limit rod 18 passes through and slides through the inside of the slide rail 19. A fixing rod 20 is fixedly connected at the middle of the opposite end of the alignment plates 16. A fixing block 21 is fixedly mounted on the upper part of the table of the C-shaped frame 2 near the middle of the front and rear sides. The fixing rod 20 passes through and slides through the inside of the fixing block 21. A return spring 22 is installed on the outside of the fixing rod 20 between the fixing block 21 and the alignment plate 16. When in use, the metal plate is inserted between the alignment plates 16. Under the limiting action of the limit rod 18 and the slide rail 19, and the rebound action of the return spring 22, the metal plate can be made to be vertical in the middle of the two sets of polishing rollers 6, which also serves as a limiting support.

[0020] Working principle: When in use, the metal plate is inserted between the alignment plates 16. Under the limiting action of the limiting rod 18 and the slide rail 19, and the rebound action of the return spring 22, the metal plate can be made to be perpendicular to the middle of the two sets of polishing rollers 6, which also serves as a limiting support. By turning on the drive motor 9, the bevel gear 10 can drive the bevel gear 7 to rotate. The rotation of the bevel gear 7 can drive the polishing roller 6 to rotate. At the same time, by opening the hydraulic cylinder 14 to retract its telescopic end, the U-shaped frame 13 can be lowered, which can eventually drive the polishing roller 6 to descend. When the polishing roller 6 descends and contacts the metal plate, it will automatically separate on both sides and naturally fit with the front and rear ends of the metal plate under the action of gravity, thereby performing grinding and polishing operations on the front and rear ends of the metal plate simultaneously.
