Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a polishing device for metal sheets. Background Technology

[0002] After processing, metal surfaces often retain various irregular marks, oxide layers, or residues. These defects significantly impact the aesthetics, mechanical properties, and corrosion resistance of metal materials, necessitating polishing to achieve a smooth, glossy finish. Polishing machines are designed specifically for this purpose.

[0003] In a Chinese patent with publication number CN220094211U entitled "A Polishing Device for Metal Sheet Processing," a pressure roller is used to simultaneously press and flatten the metal sheet surface on both sides of the polishing wheel during polishing. This ensures that the metal sheet surface remains flat during polishing, resulting in higher polishing quality. Simultaneously, due to the adjustable bolt, rotating the bolt moves the lower pressure plate on its arc surface downwards, which in turn rotates the rotating block, adjusting the height of the polishing wheel and the pressure applied to the metal sheet surface. This allows for adjustment based on the strength of different metal sheet surfaces to achieve the best polishing effect. The movable block can slide on the adjusting plate to adjust its lateral position. When adjusting the lateral position, rotating the adjusting bolt upwards raises the pressure rollers on both sides, allowing for subsequent position adjustments and preventing excessive friction between the pressure rollers and the metal sheet surface caused by lateral movement.

[0004] However, this device still has shortcomings. Most polishing wheels are fixed inside the polishing machine. This fixed method makes it inconvenient to disassemble and reassemble the polishing wheel when it is damaged and needs to be replaced or repaired. The disassembly and reassembly process is cumbersome and complicated, wasting the time and energy of the staff. At the same time, since fine dust is generated during the polishing of metal sheets and is dispersed into the air, long-term inhalation of dust-containing air by staff can easily cause lung diseases and affect the health of the staff. In order to solve the above problems, the inventor proposes a polishing device for metal sheets. Utility Model Content

[0005] To address the problems of inconvenience in disassembling and assembling polishing wheels when they are damaged and need to be replaced or repaired, and the generation of fine dust during the polishing process of metal sheets, which is dispersed into the air and may affect the health of workers, the purpose of this utility model is to provide a polishing device for metal sheets.

The two symmetrical drive slides 21 can achieve synchronous movement under the control of the controller. The top of the drive slides 21 is provided with a support column 22, and a connecting plate 23 is fixedly connected between the tops of the two support columns 22. A drive slide 24 is fixedly connected to the center of the bottom end of the connecting plate 23. The bottom end of the drive slide 24 is provided with a mounting box 25. A support box 27 is provided below the mounting box 25. A rotating rod 3 is rotatably connected to the bottom end of the support box 27. An inner groove 31 is opened at the bottom end of the rotating rod 3. A connecting rod 32 is slidably inserted into the bottom end of the rotating rod 3 and located in the inner groove 31. A polishing wheel 33 is fixedly connected to the bottom end of the connecting rod 32.

[0021] A bolt 35 is threadedly connected to the side end of the rotating rod 3 near the bottom. A screw hole 34 is opened inside the connecting rod 32, and the screw hole 34 and the bolt 35 are at the same level.

[0022] By adopting the above technical solution, the screw hole 34 is set at the same level as the bolt 35 in order to facilitate the mating of the bolt 35 and achieve the effect of limiting the connecting rod 32.

[0023] A motor 28 is fixedly connected inside the support box 27, and the output end of the motor 28 passes through the support box 27 and is fixedly connected to the rotating rod 3.

[0024] By adopting the above technical solution, the motor 28 is operated, thereby causing the fixedly connected rotating rod 3 to rotate.

[0025] An electric cylinder 26 is fixedly connected inside the mounting box 25, and the output end of the electric cylinder 26 passes through the mounting box 25 and is fixedly connected to the support box 27.

[0026] By adopting the above technical solution, the electric cylinder 26 can be operated to enable the fixedly connected mounting box 25 to lift and lower with the cooperation of the auxiliary telescopic shafts on both sides.

[0027] The mounting box 25 has several heat dissipation slots on its side.

[0028] By adopting the above technical solution, a heat dissipation groove is opened on the side of the mounting box 25 in order to dissipate the generated heat.

[0029] A pull block 14 is fixedly connected to the top of the sliding plate 13 and the center of the side near the door 12.

[0030] By adopting the above technical solution, a pull block 14 is provided at the top of the sliding plate 13 to facilitate the staff to pull the sliding plate 13 out of the protective cover 2.

[0031] A pull plate 11 is fixedly connected to the center of the side end of the door 12 near the bottom.

[0035] Working principle: When using this device, the plate to be polished is first placed above the center of the sliding plate 13. Then, the limiting structures on both sides are used to limit the plate. Then, the sliding plate 13 is moved into the protective cover 2 by the pull block 14, and the box door 12 is flipped and reset, thereby achieving the effect of sealing the polishing environment. This solves the problem that fine dust is generated during the polishing process of metal plates, which can easily affect the health of workers after being dispersed into the air.

[0036] With the cooperation of two drive slides 21 and 24 and motor 28, motor 28 drives polishing wheel 33 to polish the board. The height of polishing wheel 33 can be adjusted by operating electric cylinder 26. When polishing wheel 33 needs to be repaired, the limit of connecting rod 32 in inner groove 31 is released by turning bolt 35. At this time, polishing wheel 33 can be removed. After repair, connecting rod 32 is reinserted into inner groove 31, and screw hole 34 needs to be flush with bolt 35. Finally, turning bolt 35 will complete the effect of limiting connecting rod 32. This achieves the effect of convenient replacement of polishing wheel 33, and solves the problem of inconvenience in disassembling and assembling polishing wheel 33 when it is damaged and needs to be replaced or repaired.
