Description

Technical Field

[0001] The invention belongs to the technical field of aluminum plate casting and rolling, and in particular relates to a surface treatment device for a casting roll of a metal aluminum plate casting and rolling machine. Background Art

[0002] The casting and rolling mill is an important metal processing equipment, which is mainly used to perform plastic processing on metal billets to deform them into the required shape and size. The principle of the casting and rolling mill is to go through a series of process steps to heat, roll and cool the metal billets, and finally obtain metal products that meet the requirements. After rolling the metal aluminum plate, the metal aluminum plate will have a significant impact on the casting roller. Due to the continuous contact and friction between the metal aluminum plate and the casting roller during the rolling process, this will cause the surface of the roller to gradually wear, adhere to metal fragments, and may cause defects such as scratches or pits. These defects will not only affect the dimensional accuracy and surface quality of the roller, but may also have an adverse effect on the quality and stability of subsequent rolled products.

[0003] Therefore, in order to eliminate these wear and defects, restore the original performance of the rolls, and ensure the quality and production efficiency of rolled products, it is necessary to perform regular grinding operations on the cast rolls. Grinding can remove the wear layer, adhered metal fragments and defects on the roll surface, restore the roll surface to a smooth and precise size, thereby improving the service life of the roll and the quality of the rolled products. Through this operation, the stability and sustainability of the rolling process can be ensured, providing strong support for the processing of metal aluminum plates, so cast roll surface treatment equipment is needed.

[0004] When the surface of the cast roll is processed and the cast roll is ground by a diamond grinding wheel, the diamond grinding wheel and the cast roll rotate relative to each other and grind, which will cause wear to the grinding wheel. In addition, the grinding of the cast roll requires high precision. After the cast roll is ground by the grinding wheel for a period of time, the grinding wheel is worn, which will cause the contact between the cast roll and the grinding wheel to fail to meet the grinding requirements, thereby causing the grinding degree to fail to meet the established requirements.

The first supporting frame 11 is threadedly connected to the threaded rod 10. The threaded rod 10 is driven to rotate in the sliding seat 9 by an external driving motor, thereby driving the first supporting frame 11 to move on the sliding seat 9, driving the grinding wheel 25 to move and grind along the casting roller. The second supporting frame The support frame 12 is rotatably connected to the top of the first support frame 11, and the pushing component 14 includes a rubber sliding frame 141, and the rubber sliding frame 141 is connected to the top of the first support frame 11. A first limiting plate 142 is slidably connected in the rubber sliding frame 141, and a fixing seat 143 is provided between the first limiting plate 142 and the inner wall of the rubber sliding frame 141. The first metal magnetic block 144 is limited by the fixing seat 143 to prevent the first metal magnetic block 144 from being pulled by the attraction of the second metal magnetic block 18. The first metal magnetic block 144 is connected to the side of the first limiting plate 142 close to the second support frame 12, and a ratchet 145 is provided at the bottom of the first limiting plate 142. The bottom of the inner wall of the rubber sliding frame 141 is provided with a There is a strip pawl 146, and the ratchet 145 cooperates with the strip pawl 146. Through the ratchet 145 and the strip pawl 146, it is convenient to adjust the first metal magnetic block 144 in the rubber sliding frame 141, and it can be adjusted and used according to different needs. The second support frame 12 is rotatably connected to the side close to the first support frame 11 with a push rod 15, and the other end of the push rod 15 is connected to the second limit plate 16. The second metal magnetic block 18 is provided with a driving coil 33. Through the driving coil 33, when the first piezoelectric ceramic block 22 is subjected to pressure to generate electricity, the driving coil 33 is powered, so that the driving coil 33 generates suction to the first metal magnetic block 144, and through cooperation with the second metal magnetic block 18, the second support frame 12 is kept The second support frame 12 is stable, both sides of the second limit plate 16 are limited by the sliding rheostat 17, the sliding rheostat 17 can only move in one direction toward one side of the second support frame 12, and cannot move in the opposite direction, the second metal magnetic block 18 is connected to the side of the second limit plate 16 close to the first support frame 11, and is aligned with the first metal magnetic block 144, the top of the second support frame 12 is connected to the protective shell 13, one side of the protective shell 13 is rotatably connected to the rotating shaft 19, one end of the mounting spindle 20 is connected to the end of the rotating shaft 19 located in the protective shell 13, and the grinding wheel 25 is supported by the annular support seat 21, and the first piezoelectric ceramic block 22 arranged on the annular support seat 21 can generate an electric charge when subjected to the force of the grinding wheel 25; During the grinding process of the cast roll, the cast roll also acts on the grinding wheel 25, so that the annular support seat 21 is subjected to the reaction force transmitted by the cast roll to the grinding wheel 25, thereby causing the first piezoelectric ceramic block 22 on the annular support seat 21 to be deformed by force. When the first piezoelectric ceramic block 22 is deformed by force, based on the piezoelectric effect, when an external force acts on the first piezoelectric ceramic block 22, the positive and negative charges inside it will be relatively displaced, resulting in redistribution of charges, thereby generating an electric potential difference, and then forming an electric current; since the deformation of the first piezoelectric ceramic block 22 when subjected to force is very small, this deformation is far from sufficient to cause the longitudinal movement of the grinding wheel 25 on the rotating shaft 19, and the grinding wheel 25 is driven by the rotating shaft 19 to rotate. During the dynamic process of the movement, the reverse force on the grinding wheel 25 is continuous and uniform, which helps to maintain the dynamic balance of the system; thus, even if the first piezoelectric ceramic block 22 produces a slight deformation, this deformation will be adjusted and balanced by the system itself during the dynamic process, and will not have a significant impact on the grinding operation of the grinding wheel 25. The surface of the annular support seat 21 is connected with a latch tooth 32, and the latch tooth 32 is used to limit the sleeved grinding wheel, so that the rotating shaft 19 can drive the grinding wheel 25 to rotate, and the fixing ring 24 prevents the grinding wheel 25 from moving on the annular support seat 21, and can better transmit the reaction force of the casting roller to the annular support seat 21 during the grinding process, so that the annular support seat The first piezoelectric ceramic block 22 on 21 is more fully stressed; and in the process of the rotation of the grinding wheel 25, for the convenience of installation, there is a gap between the grinding wheel 25 itself and the annular support seat 21. Therefore, when the grinding wheel 25 is in contact with the cast roller and rotates and grinds, the reverse force transmitted by the cast roller to the grinding wheel 25 will cause the grinding wheel 25 itself to vibrate on the annular support seat 21. During the vibration of the grinding wheel 25, it will collide with the baffle plate 23 located on one side of the grinding wheel 25, causing the second piezoelectric ceramic block 34 on the side of the baffle plate 23 close to the grinding wheel 25 to be forced to vibrate. Similarly, based on the piezoelectric effect, the second piezoelectric ceramic block 34 will vibrate to generate electricity, and by cooperating with the first piezoelectric ceramic block 22, The power generation operation is performed at the same time, and neither of them is indispensable. The first piezoelectric ceramic block 22 and the second piezoelectric ceramic block 34 generate electricity at the same time. The generated current flows out through the wire, is adjusted by the converter, and then the driving coil 33 is powered at the same time. The grinding wheel 25 is located in the protective shell 13, and the mounting spindle 20 is provided with a baffle 23 and a fixing ring 24. The baffle 23 and the fixing ring 24 are used to limit and fix the installed grinding wheel 25 to prevent the grinding wheel 25 from moving on the rotating shaft 19, so as to facilitate the replacement of the grinding wheel 25. The baffle 23 and the fixing ring 24 are respectively located on both sides of the annular support seat 21, and the plurality of the second piezoelectric ceramic blocks 34 are all located on the side of the baffle 23 close to the grinding wheel 25.

[0021] Embodiment 2 Based on Example 1, please refer to Figure 2 , Figure 4 and Figure 6 , Specifically, the spray assembly 29 includes a connecting frame 291, the connecting frame 291 is connected to one side of the second support frame 12, the bottom of the connecting frame 291 is connected to a delivery pipe 292, the delivery pipe 292 is located on one side of the grinding wheel 25, and one side of the inner wall of the delivery pipe 292 is connected to two flow heads 294, the two flow heads 294 are evenly distributed on the inner wall of the delivery pipe 292, and the two flow heads 294 are each provided with a nozzle 295, and the two nozzles 295 are located between the two flow heads 294. On the side away from the grinding wheel 25, the two nozzles 295 provided on the two jet heads 294 spray toward both sides, so that the gas generated by the high-pressure air pump 30 and the coolant put into the delivery pipe 292 through the connecting pipe 28 are mixed, and the water pressure of the coolant is increased, so that the water pressure of the coolant sprayed out becomes larger, and the cooling effect on the grinding wheel 25 and the casting roller is better, and the cleaning effect of the debris remaining on the casting roller is better. One side of the delivery pipe 292 is connected to a plurality of nozzles 293, and the spraying direction of the plurality of nozzles 293 is toward the grinding wheel. 25 is in contact with the casting roll, one side of the first support frame 11 is connected to a coolant tank 26, the bottom of the inner wall of the coolant tank 26 is connected to a water pump 27, the output end of the water pump 27 is connected to a connecting pipe 28, the other end of the connecting pipe 28 passes through the coolant tank 26 and the delivery pipe 292 and is connected to the inner wall of the delivery pipe 292, and is located between the two flow jet heads 294, one side of the second support frame 12 is connected to a high-pressure air pump 30, the output end of the high-pressure air pump 30 is connected to a ventilation pipe 31, the The other end of the ventilation pipe 31 is connected with the two flow heads 294 in the conveying pipe 292. A collecting groove 5 is provided on the top of the base 1, and the collecting groove 5 is located in the middle of the two chutes 3. A filter screen 6 is placed in the collecting groove 5 to flush the debris generated by the casting roller mill and let it fall into the collecting groove 5. The coolant is filtered through the filter screen 6 to facilitate the recycling of the coolant. A water outlet 7 is provided on one side of the base 1, and the water outlet 7 is connected with the collecting groove 5. A connecting valve 8 is provided on the water outlet 7.

[0022] The working principle and use process of the present invention: When the present invention is in use, the staff adjusts the second operating table 4 to make the second operating table 4 slide in the slide groove 3 on the base 1, approach or move away from the first operating table 2, and adjusts the casting rolls of different lengths. After the adjustment, the second operating table 4 is fixed. After the second operating table 4 is fixed, the used casting roll is placed between the first operating table 2 and the second operating table 4 for limited fixation. After fixation, the staff installs the grinding wheel 25 on the mounting spindle 20, moves the grinding wheel 25 to the position of the annular support seat 21, supports the grinding wheel 25 through the annular support seat 21, and then sleeves the fixing ring 24 on the mounting spindle 20, and cooperates with the baffle 23 to fix the grinding wheel 25. The grinding wheel 25 is fixed, and the staff aligns the grinding wheel 25 with the surface of the cast roll in use, drives the fixed cast roll to rotate through the first operating table 2 and the second operating table 4, drives the rotating shaft 19 to rotate through the external driving motor, drives the installation spindle 20 to rotate through the rotating shaft 19, thereby driving the grinding wheel 25 to rotate in the protective shell 13, and the cast roll and the grinding wheel 25 rotate in opposite directions, so that the cast roll is ground by the grinding wheel 25. During grinding, the threaded rod 10 is driven to rotate by the external driving motor, thereby driving the first support frame 11 to move on the sliding seat 9, thereby driving the grinding wheel 25 to perform an overall grinding operation on the surface of the cast roll. During grinding, the water pump 27 works, and the water pump 27 is in the coolant tank 26. The cooling liquid is extracted from the inner part of the cooling device, and is passed through the connecting pipe 28, and is put into the delivery pipe 292. The cooling liquid is divided through the delivery pipe 292 and sprayed out at multiple nozzles 293 to spray and cool the grinding wheel 25 that is grinding, and to cool and clean the grinding position of the casting roller, so that the debris generated by the grinding can fall smoothly into the collecting tank 5, which is convenient for the subsequent application of the protective agent to the casting roller. When the cooling liquid is sprayed out from the nozzle 293, the high-pressure air pump 30 works, and the high-pressure air pump 30 extracts air and compresses the extracted gas, and then puts the compressed gas into the ventilation pipe 31, and sprays out through the flow nozzle 294 on the inner wall of the delivery pipe 292 through the ventilation pipe 31, so as to pressurize the cooling liquid put into the delivery pipe 292, thereby cooling the cooling liquid. When the liquid is sprayed out from the nozzle 293, the water pressure is greater, and the circulation of the coolant is accelerated, which can make the cooling effect better and the cleaning effect of the casting roller better. The sprayed coolant carries the debris generated by grinding and falls into the collecting tank 5. The coolant can be simply filtered through the filter screen 6 in the collecting tank 5. The filtered coolant is discharged through the water outlet 7. The staff can connect the pipeline to the connecting valve 8 to extract the coolant for reuse, and the delivery pipe 292 is connected to one side of the second support frame 12. Therefore, it can be ensured that during the mobile grinding process, the delivery pipe 292 moves synchronously with the movement of the grinding wheel 25 to ensure that the spraying position of the nozzle 293 is maintained at the contact position between the grinding wheel 25 and the casting roller.

[0023] During the process of grinding the cast roller by the grinding wheel 25, the grinding wheel 25 and the cast roller interact with each other, and then the grinding wheel 25 exerts force on the cast roller to achieve the purpose of grinding. Similarly, the cast roller will also generate an opposite force on the grinding wheel 25. During grinding, the force generated by the cast roller on the grinding wheel 25 is transmitted to the center of the grinding wheel 25, and through the center position of the grinding wheel 25, pressure is generated on the annular support seat 21 on which the main shaft 20 is installed at the position of the grinding wheel 25. The first piezoelectric ceramic block 22 on the annular support seat 21 is also subjected to pressure. Based on the principle of piezoelectric effect, when the first piezoelectric ceramic block 22 is compressed, the positive and negative charges inside it will undergo relative displacement, resulting in bound charges of opposite signs at both ends of the material. The current generated by the material contacts the connecting wire and is converted into After the conversion, it is transmitted to the second metal magnetic block 18. Similarly, there is a gap between the grinding wheel 25 itself and the annular support seat 21. Therefore, when the grinding wheel 25 is fitted to the cast roller and rotates and grinds, the reverse force transmitted from the cast roller to the grinding wheel 25 will cause the grinding wheel 25 itself to vibrate on the annular support seat 21. During the vibration of the grinding wheel 25, it will collide with the baffle 23 located on one side of the grinding wheel 25, causing the second piezoelectric ceramic block 34 on the side of the baffle 23 close to the grinding wheel 25 to vibrate under force. Similarly, based on the piezoelectric effect, the second piezoelectric ceramic block 34 will vibrate to generate electricity, and the first piezoelectric ceramic block 22 will cooperate with the first piezoelectric ceramic block 22 to generate electricity at the same time. Both are indispensable. The first piezoelectric ceramic block 22 and the second piezoelectric ceramic block 34 generate electricity at the same time. The current flows out through the wire, is adjusted by the converter, and is powered to the drive coil 33 at the same time. The drive coil 33 set on the second metal magnetic block 18 works, thereby strengthening the magnetism of the second metal magnetic block 18, so that the second metal magnetic block 18 increases the attraction to the first metal magnetic block 144, and the magnetism of the first metal magnetic block 144 and the second metal magnetic block 18 are in opposite states, opposite charges attract each other, and the second metal magnetic block 18 will be attracted by the first metal magnetic block 144, thereby pulling the push rod 15 to remain stable, so that the tension on the second metal magnetic block 18 and the downward gravity on the second support frame 12 are balanced, so that the grinding wheel 25 maintains the contact pressure with the casting roller, thereby completing the grinding operation, but the first metal magnetic block 144 A fixing seat 143 is arranged on one side, and the fixing seat 143 provides support for the first metal magnetic block 144. The ratchet 145 arranged at the bottom of the first limiting plate 142 and the strip pawl 146 arranged at the bottom of the inner wall of the rubber sliding frame 141 cooperate to facilitate the adjustment of the position of the first metal magnetic block 144. The adjustment is made according to different usage requirements to prevent the first metal magnetic block 144 from moving due to the attraction of the second metal magnetic block 18. During the grinding process, the second support frame 12 can be kept fixed on the first support frame 11, so that the grinding wheel 25 can be normally ground on the casting roller. During the grinding process, the surface grinding accuracy of the casting roller is high. The casting roller will also wear the surface of the grinding wheel 25. When the grinding wheel 25 is worn,This will cause the gap between the grinding wheel 25 and the casting roller to become larger, and the grinding degree of the casting roller by the grinding wheel 25 will not meet the established requirements. When the grinding wheel 25 is worn and the gap between the casting rollers becomes larger, the pressure generated by the casting roller on the grinding wheel 25 will decrease, which will cause the force transmitted by the grinding wheel 25 to the center position to decrease, thereby causing the force on the first piezoelectric ceramic block 22 to decrease, resulting in a decrease in the charge generated by the first piezoelectric ceramic block 22, and a decrease in the current transmitted to the drive coil 33, thereby causing the current generated by the drive coil 33 to decrease. At this time, the downward gravity applied to the second support frame 12 is greater than the attraction generated between the first metal magnet 144 and the second metal magnet 18. Therefore, the second support frame 12 will rotate on the first support frame 11, driving the second limit plate 16 to move, and driving the second metal magnet 18 to move to the side away from the first metal magnet 144, through the second support The support frame 12 rotates downward, so that the grinding wheel 25 moves downward and approaches the position of the casting roller. After the casting roller is attached to the predetermined position, the force on the first piezoelectric ceramic block 22 is restored, so that the current generated by the first piezoelectric ceramic block 22 is restored, so that the magnetism generated by the driving coil 33 set on the second metal magnetic block 18 is in cooperation with the second metal magnetic block 18, and the gravity on the second support frame 12 itself is balanced again. In addition, due to the sliding rheostat 17 set on both sides of the second limit plate 16, the second metal magnetic block 18 is prevented from being attracted by the first metal magnetic block 144, driving the second support frame 12 to rotate in the opposite direction, so that the second support frame 12 is kept stable, and the grinding wheel 25 at the bottom of the second support frame 12 is kept stable and will not fall or rise, so that the overall grinding degree of the casting roller is kept consistent. In the process of continuous grinding, the grinding wheel 25 is adjusted in time until the grinding is completed.
