[0001] The present invention relates to the technical field of aluminum plate, strip and foil rolling working rolls, and in particular to a grinding device for processing aluminum plate, strip and foil rolling working rolls and a processing technology thereof. Background Art

[0002] With the widespread application of aluminum and aluminum alloys in aerospace, packaging, construction, home appliances, and other fields, the market demand for aluminum sheet, strip, and foil continues to increase. This requires aluminum processing companies to possess efficient and high-precision production capabilities. Rollers, as essential tools in the aluminum sheet, strip, and foil rolling process, have a direct impact on the surface quality and geometric accuracy of the rolls, significantly affecting the quality of the rolled products, production costs, and productivity. Therefore, roll processing and grinding technologies have become crucial for improving aluminum production levels.

[0003] Due to long-term processing, the surface of the processing roller will become uneven. In order to ensure the accuracy of the processing roller and the grinding surface effect, the grinding wheel needs to be aligned with the raised area outside the processing roller to avoid excessive strain on the grinding wheel. The existing grinding equipment is not convenient for calibrating the surface area of the roller, which will affect the processing accuracy of the roller and increase the damage to the grinding wheel. When processing rollers of different specifications, the grinding equipment is not convenient for adjusting the cooling mechanism of the grinding wheel, which may cause uneven cooling, local overheating or overcooling, and thus affect the surface finish and dimensional accuracy of the roller.

[0017] S1: Surface treatment:

[0018] Mechanical grinding is used to remove grease, dirt and other impurities on the surface of the roller to an average surface roughness of 0.1-2.0 microns. Then, pickling is used to remove oxides and impurities on the surface of the roller to obtain a clean surface. Finally, the roller is activated before plating to enhance the adhesion of the coating.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention can adjust the diameter of the spray head according to the size of the processing roller by providing a size adjustment component, a connecting plate and a second electric push rod. For small-sized working rollers with a small surface area, the nozzle diameter is simultaneously reduced to spray the coolant into a limited area, avoiding splashing of coolant or insufficient coverage, ensuring uniform cooling of the roller surface. For large-sized working rollers with a large surface area, the nozzle diameter is simultaneously expanded to avoid insufficient local cooling or excessive temperature gradient caused by too small a nozzle.

[0025] 2. The present invention can detect the uneven area on the roller surface and calibrate the position of the grinding wheel through the pressure sensor, mounting cylinder and resistance rod so that it contacts the raised area outside the processing roller. When grinding the roller surface, it can avoid the grinding wheel from exerting too much force, reduce the wear of the grinding wheel, and improve the processing accuracy of the roller.

[0026] 3. The present invention, through the amplitude adaptor assembly, mounting bracket, and spray head, gradually adjusts the spray head's swing amplitude as the grinding equipment gradually polishes the roller surface. As the grinding depth increases, the roller surface temperature and cutting heat distribution change. The amplitude adaptor assembly precisely matches the spray head's swing amplitude with the cooling requirements of the current polishing stage, avoiding thermal deformation and resource waste caused by insufficient or excessive cooling.

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.

[0039] The size adjustment component includes a mounting cylinder 162 mounted on the protruding end of the second electric push rod 9, a pressure sensor 161 is mounted on the top end of the mounting cylinder 162, and a resistance rod 163 is provided for limiting sliding inside the mounting cylinder 162. It also includes an adjustment cylinder 164 rotatably connected to the bottom of the spray head 15, a gear ring 165 is mounted on the bottom surface of the adjustment cylinder 164, the bottom end of the spray head 15 is rotatably connected to a gear 166 through a bracket, a sleeve 167 is mounted on the top end of the gear 166, and a fourth electric push rod 168 is mounted on the bottom end of the spray head 15. The protruding end of the fourth electric push rod 168 is limited and slides in the sleeve 167, so as to adjust the diameter of the spray head 15 according to the size of the processing roller. The surface area of the small-sized working roller is small, so the diameter of the nozzle is synchronously reduced. The surface area of the large-sized working roller is large, so the diameter of the nozzle is synchronously expanded to avoid insufficient local cooling or excessive temperature gradient due to a too small nozzle;

[0040] The existing grinding equipment is not convenient for calibrating the surface area of the roller body, and the grinding equipment is not convenient for adjusting the cooling mechanism of the grinding wheel 13. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows. When processing the roller body, the roller body is first placed inside the contact table 5. At this time, the controller pushes the contact table 5 up through the first electric push rod 6 to align the roller body with the clamping seat 3. At this time, the controller drives the clamping seat 3 to clamp and fix the roller body, and then the motor drives the roller body to rotate. The extended end of the second electric push rod 9 drives the mounting cylinder 162 to descend, so that the bottom end of the interference rod 163 contacts the surface of the roller body, and then the electric guide rail drives the support frame 7 to slide on the surface of the bottom plate 1 until the interference rod 163 detects the surface of the roller body. While the controller drives the output end of the first electric push rod 6 to rise, the controller will drive the extended end of the fourth electric push rod 168 to extend appropriately, and the extended end of the fourth electric push rod 168 is in the sleeve The fourth electric push rod 168 slides within the limited position in the spiral groove inside 167, and the fourth electric push rod 168 drives the gear 166 to rotate when sliding within the limited position inside the sleeve 167. The gear 166 rotates through the ring gear 165 to drive the adjusting cylinder 164 to rotate.

When the bottom end of the interference rod 163 contacts the surface of the roller body, the raised area on the surface of the roller body resists the interference rod 163. The pressure sensor 161 detects the maximum pressure on the interference rod 163, and drives the extended end of the fourth electric push rod 168 to retract appropriately through the controller. At this time, the extended end of the fourth electric push rod 168 drives the gear 166 to rotate in the opposite direction. The gear 166 rotates in the opposite direction and drives the adjusting cylinder 164 to rotate in the opposite direction through the ring gear 165. The rotating ring 1610 drives the closing plate 169 to slide in the sliding groove at the bottom end of the sprinkler head 15, thereby appropriately expanding the output diameter of the sprinkler head 15.

[0043] As an embodiment of the present invention, a spiral groove is opened inside the sleeve 167, and a protrusion is installed at the protruding end of the fourth electric push rod 168. The protrusion slides within the spiral groove inside the sleeve 167, and the gear 166 is engaged with the ring gear 165. The protruding end of the fourth electric push rod 168 can drive the sleeve 167 to rotate, and the sleeve 167 drives the ring gear 165 to rotate through the gear 166.

[0044] As an embodiment of the present invention, a slide groove is provided at the bottom end of the sprinkler head 15, and a closing plate 169 is slidingly limited in the slide groove. A swivel 1610 is rotatably connected to the bottom end of the sprinkler head 15, and the bottom end of the swivel 1610 is connected to the bottom of the inner wall of the adjustment cylinder 164. The adjustment cylinder 164 can adjust the diameter of the bottom end of the sprinkler head 15 when rotating.

[0045] As an embodiment of the present invention, there are six groups of closing plates 169 , which are evenly distributed in a circular shape at the bottom end of the sprinkler head 15 , and the bottom ends of the closing plates 169 slide within the rotating ring 1610 in a limited manner.

[0046] As an embodiment of the present invention, the amplitude adaptation assembly includes a first oil tank 171 installed at the back end of the fixed frame 14, and a first piston rod 172 is limited and sliding inside the first oil tank 171, and a connecting frame 173 is installed at the protruding end of the first piston rod 172, and an electromagnet 174 is installed at the bottom of the connecting frame 173. A metal plate is installed at the top of the mounting frame 10, and a fifth electric push rod 175 is installed at the side end of the fixed frame 14 through a bracket, and a movable frame 176 is installed at the protruding end of the fifth electric push rod 175, and a second oil tank 177 is installed at the top of the movable frame 176. A second piston rod 178 is limited and sliding inside the second oil tank 177, and a resistance frame 179 is installed at the end of the second piston rod 178. The bottom end of the resistance frame 179 slides within the movable frame 176, so that the swing amplitude of the spray head 15 can be gradually adjusted when the grinding equipment grinds the roller surface step by step.

[0047] As an embodiment of the present invention, a spring is sleeved on the surface of the first piston rod 172, a resistance block is installed inside the resistance frame 179, a slope is provided at the bottom end of the resistance block, and the resistance blocks are symmetrically distributed inside the resistance frame 179. The first oil tank 171 and the second oil tank 177 are connected by a hose, and the slope at the bottom end of the resistance block can adjust the movement amplitude of the sprinkler head 15.

[0048] Working principle: When processing the roller body, first place the roller body inside the contact table 5. At this time, the controller pushes the contact table 5 up through the first electric push rod 6 to align the roller body with the clamping seat 3. At this time, the controller drives the clamping seat 3 to clamp and fix the roller body, and then the motor drives the roller body to rotate. The extended end of the second electric push rod 9 drives the mounting cylinder 162 to descend, so that the bottom end of the contact rod 163 contacts the surface of the roller body, and then drives the support frame 7 to slide on the surface of the bottom plate 1 through the electric guide rail until the contact rod 163 detects the surface of the roller body. While the controller drives the output end of the first electric push rod 6 to rise, the controller will drive the extended end of the fourth electric push rod 168 to extend appropriately, and the extended end of the fourth electric push rod 168 slides within the spiral groove inside the sleeve 167, and the fourth electric push rod 168 is limited inside the sleeve 167 When sliding, it drives the gear 166 to rotate, and the rotation of the gear 166 drives the adjustment cylinder 164 to rotate through the gear ring 165, and the rotating ring 1610 drives the closing plate 169 to slide in the sliding groove at the bottom end of the sprinkler head 15, thereby reducing the output diameter of the sprinkler head 15. When the bottom end of the interference rod 163 contacts the surface of the roller body, the raised area on the surface of the roller body resists the interference rod 163. The pressure sensor 161 detects the maximum pressure on the interference rod 163 and drives the extended end of the fourth electric push rod 168 to appropriately retract through the controller. At this time, the extended end of the fourth electric push rod 168 drives the gear 166 to rotate in the opposite direction. The gear 166 rotates in the opposite direction and drives the adjustment cylinder 164 to rotate in the opposite direction through the gear ring 165. The rotating ring 1610 drives the closing plate 169 to slide in the sliding groove at the bottom end of the sprinkler head 15, thereby appropriately expanding the output diameter of the sprinkler head 15.

[0049] The controller drives the motor to rotate the grinding wheel 13, and drives the extended end of the third electric push rod 11 to drive the grinding wheel 13 to contact the raised position on the roller surface. At this time, the controller drives the extended end of the fifth electric push rod 175 to move back and forth, driving the spray head 15 to swing horizontally inside the fixed frame 14. At the same time that the extended end of the third electric push rod 11 contacts the raised position on the roller surface, the controller drives the electromagnet 174 to work. At this time, the electromagnet 174 is adsorbed on the metal plate, and the grinding wheel 13 grinds the roller surface. Afterwards, the third electric push rod 11 will push the grinding wheel 13 to grind the roller body step by step. When the cover shell 12 moves, the fixed frame 14 will pull the first oil tank 171. At this time, the oil inside the first oil tank 171 will be injected into the second oil tank 177. The oil inside the second oil tank 177 pulls the second piston rod 178 to descend, and the second piston rod 178 drives the resistance frame 179 to descend. At this time, when the extended end of the fifth electric push rod 175 moves back and forth, the swing amplitude of the sprinkler head 15 inside the fixed frame 14 will be increased.

[0051] S1: Surface treatment:

[0052] Mechanical grinding is used to remove grease, dirt and other impurities on the surface of the roller to an average surface roughness of 0.1-2.0 microns. Then, pickling is used to remove oxides and impurities on the surface of the roller to obtain a clean surface. Finally, the roller is activated before plating to enhance the adhesion of the coating.

[0053] S2: Chrome plating:

[0054] The roller that has been surface treated and activated before plating is immersed in a hard chrome plating solution composed of chromic acid, sulfuric acid, hard chrome plating additives and pure water.

9. A process for processing aluminum sheet, strip and foil rolling work rolls, applicable to the grinding equipment for processing aluminum sheet, strip and foil rolling work rolls as claimed in claim 8, characterized in that: The method comprises the following steps: S1: Surface treatment: Mechanical grinding is used to remove grease, dirt and other impurities on the surface of the roller to an average surface roughness of 0.1-2.0 microns. Then, pickling is used to remove oxides and impurities on the surface of the roller to obtain a clean surface. Finally, the roller is activated before plating to enhance the adhesion of the coating. S2: Chrome plating: The roller that has been surface treated and activated before plating is immersed in a hard chrome plating solution composed of chromic acid, sulfuric acid, hard chrome plating additives and pure water. An electric current is applied to reduce the chromium ions on the roller surface and deposit them into a hard chrome layer with a thickness of 3 microns to 15 microns. S3: Post-processing: The residual plating solution and impurities on the surface of the roller are cleaned to ensure a smooth and clean surface. The roller surface is then polished and dehydrogenated to improve the performance of the chromium layer.
