Description
Technical Field
[0001] This utility model relates to the field of polishing equipment technology, specifically a roller polishing device that can rapidly cool down. Background Technology
[0002] Rolls are the main working components and tools on rolling mills that cause continuous plastic deformation of metal. In the production and processing of rolls, it is necessary to improve their surface finish, so polishing is performed on the roll surface to remove machining marks, oxide scale, burrs, etc. Rolls can be polished using polishing rollers. The polishing rollers contact and move relative to the roll body surface to remove surface defects, improving surface finish and precision. Its working principle is mainly based on friction and material removal mechanisms, and can be combined with auxiliary materials such as abrasive media and polishing fluids to achieve efficient polishing.
[0003] Based on this, a search on the patent website revealed that application number 202320939194.6 discloses a roller surface polishing device, including a polishing mechanism and a clamping mechanism.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This utility model discloses a roller polishing device with rapid cooling capability. When using the device, the roller is pre-fixed to the first fixed component via a second fixing component. Before installing the roller, the distance between the second and first fixing components is at its maximum and greater than the length of the roller. The two ends of the roller are aligned with the second and first fixing components respectively. One end of the roller is placed in the cavity turntable of the first fixing component, with the roller end positioned between the first and second clamping plates. Based on the length of the roller, the third motor is activated, driving the first threaded rod to rotate forward. The first threaded rod drives the moving block and the mounting block to move horizontally towards the roller until the other end of the roller is in the cavity turntable on the second fixed component. The third motor is then turned off, and simultaneously, two sets of automatic telescopic rods are activated. The telescopic rod extends the second clamping plate until it tightly clamps the first clamping plate on the upper and lower sides of the roll end. The second and first fixing components position the two ends of the roll. Then, the user simultaneously drives two sets of hydraulic cylinders, which move the two sets of support plates and the polishing roller closer to the roll body until the outer wall of the polishing roller contacts the outer wall of the roll body. The hydraulic cylinders are then closed. The first motor is turned on, which drives the polishing roller to rotate clockwise. At the same time, the user turns on two sets of second motors, which simultaneously drive the two sets of groove turntables to rotate counterclockwise. In turn, the two sets of groove turntables drive the roll to rotate counterclockwise. The polishing roller rotates in the opposite direction to the roll being processed, and the two rollers are in contact with each other. The surface of the roll body section on the roll can be polished by the polishing roller. The operation is simple and quick, and convenient for users.
[0022] 2. Pre-fill the water tank with cooling water. During the polishing process of the rolls, as the surface temperature of the rolls rises, the user can turn on the water pump. The water pump draws the cooling water from the water tank into the water passage chamber through the pipes, and multiple sets of spray nozzles spray the cooling water onto the rolls, cooling them down. Simultaneously, the cooling water helps to wash away debris from the roll surface. Water entering the support base will also exit through multiple drain holes. Cooling water on the top surface of the base will flow into the collection chamber through multiple drain channels. The filter screen in the collection chamber filters the cooling water, leaving debris and impurities on the screen. The filtered cooling water then drains through the drain pipe. After leaving the device, this operation allows for the unified treatment of used cooling water, preventing the direct discharge of cooling water mixed with waste materials into the external environment and avoiding environmental pollution. To prevent filter clogging, the user can turn on the drive motor when using the collection chamber. The drive motor drives the reciprocating screw rod to rotate, which in turn drives the reciprocating block and cleaning brush plate to reciprocate. The cleaning brush plate can reciprocate to clean the filter screen, preventing clogging and accelerating the discharge efficiency of filtered cooling water. This setup, through the cooling mechanism, facilitates the cooling of the roll surface, preventing excessive temperature during roll polishing and improving polishing quality.

[0042] In summary, this utility model discloses a roller polishing device with rapid cooling capability. The roller body is the main working part of the roller, and it is the middle part of the roller. The polishing device mainly removes defects on the roller body and improves the surface smoothness of the roller body. When using the device, the roller is pre-fixed to the first fixing component 22 via the second fixing component 23. Before installing the roller, the distance between the second fixing component 23 and the first fixing component 22 is at its maximum and is greater than the length of the roller. The two ends of the roller are respectively fixed to the second fixing component 23. Corresponding to the first fixing component 22, one end of the roll is first placed in the grooved turntable 232 of the first fixing component 22, with the end of the roll positioned between the first clamping plate 233 and the second clamping plate 234. Based on the length of the roll, the third motor 235 is activated, driving the first threaded rod 236 to rotate forward. The first threaded rod 236 drives the moving block 237 and the mounting block 238 to move horizontally towards the roll until the other end of the roll is positioned in the grooved turntable 232 on the second fixing component 23. The third motor 235 is turned off, and the two sets of automatic telescopic rods 239 are simultaneously activated. The automatic telescopic rods 239 drive the second clamping plate 234 to extend until the second clamping plate 234 and the first clamping plate 233 are tightly clamped on the upper and lower sides of the roll end. The two ends of the roll are positioned by the second fixing component 23 and the first fixing component 22. Then, the user simultaneously drives the two sets of hydraulic cylinders 24. The two sets of hydraulic cylinders 24 drive the two sets of support plates 26 and the polishing roller 27 to move closer to the roll body until the outer wall of the polishing roller 27 is flush with the outer wall of the roll body. The hydraulic cylinder 24 is closed due to mutual contact; the first motor 25 is turned on, which drives the polishing roller 27 to rotate clockwise. At the same time, the user turns on two sets of second motors 231, which simultaneously drive two sets of cavity turntables 232 to rotate counterclockwise. In turn, the two sets of cavity turntables 232 drive the roll to rotate counterclockwise. The polishing roller 27 rotates in the opposite direction to the rotation direction of the roll being processed, and the two rollers are in contact with each other. The surface of the roll body section on the roll can be polished through the polishing roller 27. The operation is simple and quick, and convenient for users.
[0043] In this application, the hydraulic cylinder 24, the first motor 25, the third motor 235, the drive motor 16, and the two sets of second motors 231 all use waterproof drive components. The first threaded rod 236 and the reciprocating threaded rod 17 are made of corrosion-resistant materials, using stainless steel with a hard chrome plating finish. Therefore, they can completely adapt to acidic or alkaline environments. Thus, the first threaded rod 236 and the reciprocating threaded rod 17 mentioned in this application will not be corroded by liquids. Cooling water is pre-filled into the water tank 31. During the polishing of the rolls, as the surface temperature of the rolls rises, the user can turn on the water pump 32. The water pump 32 draws the cooling water from the water tank 31 into the water passage chamber 33 through the pipes, and multiple sets of spray nozzles 34 spray the cooling water onto the rolls to cool them down. At the same time, the cooling water helps to wash away debris on the surface of the rolls. Water entering the support base 21 will also exit through multiple sets of drain holes 211. The cooling water flows into the collection chamber 13 through multiple sets of drain channels 111. The filter screen 14 in the collection chamber 13 filters the cooling water, leaving debris and impurities on the filter screen 14. The filtered cooling water then leaves the device through the drain pipe 12. This operation allows for unified treatment of the used cooling water, avoiding the direct discharge of cooling water mixed with waste into the external environment, which would cause environmental pollution. To prevent the filter screen 14 from clogging, the user can turn on the drive motor 16 when using the collection chamber 13. The drive motor 16 drives the reciprocating threaded rod 17 to rotate, which in turn drives the reciprocating block 18 and the cleaning brush plate 15 to reciprocate. The cleaning brush plate 15 can perform reciprocating cleaning of the filter screen 14, preventing clogging and accelerating the discharge efficiency of the filtered cooling water. This setup, through the cooling mechanism, allows the device to easily cool the surface of the roll, avoiding excessive temperature during the roll polishing process and improving the polishing quality.
