Description

Technical Field

[0001] This application belongs to the field of precision machining of rolling mill rolls and plate shape control, specifically relating to a rolling mill roll anti-convexity grinding and positioning device. Background Technology

[0002] In recent years, with the increasing demands for dimensional accuracy and yield of copper-aluminum composite sheets from downstream industries such as new energy, electronics manufacturing, and automotive lightweighting, our company faces growing challenges in sheet shape control during the casting and rolling process. In actual production, there are significant differences in the transverse thickness of the sheets, with the center being thicker and the sides thinner, and the center thickness exceeding the sides by 0.23–0.25 mm. This problem becomes more pronounced after slitting, leading to insufficient edge thickness and frequent dimensional deviations in customer products. This severely impacts the consistency and yield of downstream processing. Simultaneously, reduced edge utilization increases material consumption per unit output, lowers the yield, and creates cost pressures and customer quality complaint risks for the company. Sheet shape deviation has become a major bottleneck restricting the company's stable product delivery and entry into the high-end market.

[0003] Currently, most roll grinding devices on the market use a single fixed grinding path, which makes it difficult to accurately match the anti-convexity design requirements and lacks a targeted cooling mechanism. During the grinding process, on the one hand, due to insufficient positioning accuracy, it is impossible to achieve precise processing of the preset curved surface of the roll; on the other hand, the heat generated by grinding can easily cause the local temperature of the roll to be too high, causing thermal deformation, which further affects the processing accuracy and cannot meet the requirements of high-precision sheet metal production for roll use. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] To address this, this application provides a roll anti-convexity grinding positioning device. Through the coordinated design of a precise positioning grinding structure and an all-around cooling system, it solves the problems of insufficient positioning accuracy and the impact of grinding thermal deformation on processing quality in traditional roll grinding devices, meeting the processing requirements for roll anti-convexity in high-precision sheet metal production. Structurally, the device uses a mounting frame as a base support, placing the roll body on a support bed. Multi-dimensional precise adjustment is achieved through a processing mechanism: the sliding bracket can move laterally along the first and second guide rails, providing a stable movement path for the grinding head along the roll's axial direction; the first height adjustment component drives the mounting plate to rise and fall as a whole, adapting to the initial processing distance requirements of rolls with different diameters; the telescopic plate extends and retracts along the length of the mounting plate, finely adjusting the radial processing range of the grinding head; the second height adjustment component realizes the grinding... The grinding head undergoes micron-level height fine-tuning, coupled with preset anti-convexity parameters in the height control box, ensuring precise matching between the grinding head's movement trajectory and the roll's anti-convexity design contour. Ultimately, a preset curved surface is machined on the rotating roll body surface. Simultaneously, the cooling mechanism works in sync with the machining mechanism: the water tank supplies water to the cooling water nozzles and internal cooling channels of the support bed through pipelines. The cooling water nozzles spray cooling water directly towards the contact area between the grinding head and the roll body, quickly dissipating grinding heat. The first, second, third, and fourth cooling water channels within the support bed are connected, forming a comprehensive cooling network to cool the roll body and support bed as a whole. After the cooling water is fully cooled by the guide plate, it is discharged through the outlet, preventing the roll from deforming due to localized overheating during the grinding process and further ensuring machining accuracy.

[0042] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects:

[0043] 1. This utility model achieves a breakthrough improvement in the positioning accuracy of roll grinding. It solves the positioning deviation problem of traditional devices through a dual height adjustment mechanism. Traditional devices often rely on a single fixed adjustment structure, which is difficult to match complex anti-convexity contours. In this application, the first height adjustment component can drive the entire mounting plate to rise and fall, adapting to the initial processing distance of rolls with different diameters. The second height adjustment component can achieve fine-tuning of the height. Combined with the anti-convexity parameters preset in the height control box, it ensures that the movement trajectory of the grinding head precisely matches the design contour of the roll. The processed roll can significantly improve the lateral thickness deviation of the sheet metal, completely solving the problem of the sheet metal being thicker in the middle and thicker on both sides. Addressing the industry pain point of thinness; simultaneously, it innovatively designs a targeted cooling and full-area heat dissipation synergistic cooling system, overcoming the problem of heat deformation during grinding in traditional equipment. Traditional cooling methods are mostly single external sprays, and uneven heat dissipation can easily lead to local overheating and deformation of the rolls. In this application, the cooling water nozzles directly and precisely spray towards the grinding contact area, quickly removing the high temperature from the heat source. Multiple sets of cooling water channels inside the support bed are interconnected, forming a full-area cooling network covering the area below the rolls and both sides of the support bed. With the help of guide plates to guide the cooling water to flow fully, the surface temperature of the rolls remains stable during the grinding process, significantly reducing the amount of heat deformation and avoiding the problem of heat deformation caused by grinding. Temperature fluctuations affect processing accuracy, necessitating the maintenance of roll surface profile stability. Furthermore, this device boasts strong adaptability and high operational efficiency, reducing usage costs and lowering the operational threshold. Traditional devices are often designed for specific roll specifications, lacking versatility. This application, through the lateral movement of the sliding bracket, adjustment of the telescopic plate length, and adaptability adjustment of the first height adjustment component, is compatible with various roll specifications, eliminating the need for separate equipment for different rolls. Simultaneously, the height control box can preset anti-convexity processing parameters, and the water storage tank ensures a continuous supply of cooling water, reducing manual adjustment and water replenishment operations, significantly improving processing efficiency, and simplifying the operation process. Technicians can learn to operate the equipment with simple training, reducing labor costs and operational error risks. Finally, structural optimization achieves a dual improvement in processing quality and production efficiency, providing a guarantee for the production of high-end sheet materials. On the one hand, precise anti-convexity grinding significantly improves the compliance rate of edge thickness of sheet materials rolled by the rolls, reducing the scrap rate caused by dimensional deviations and significantly improving material utilization. On the other hand, stable processing accuracy and cooling effect extend the service life of the rolls, reduce the frequency of roll replacement, and reduce quality complaints from downstream customers. This helps enterprises break through the bottleneck of high-end market access and enhance product competitiveness and market share.

[0100] The grinding path of the processing mechanism 300 matches the anti-convexity design contour of the roll body 1, and a preset curved surface is formed by lateral movement and height adjustment.

[0101] In this embodiment, the rotation of the roll body 1, combined with the lateral movement and height adjustment of the grinding head 311, can achieve full circumferential grinding of the roll surface; the grinding path of the processing mechanism 300 is preset by the height control box 307 and precisely matched with the anti-convexity design contour, ensuring that the final processed roll surface can offset the deformation of the plate during the rolling process and solve the problem of the plate shape that is thick in the middle and thin on both sides.

[0102] Working principle: The roll anti-convexity grinding and positioning device uses the mounting frame 2 as the overall support base. The support bed 401 at the bottom of the mounting frame 2 is used to place the roll body 1, and the roll body 1 can rotate freely on the support bed 401, providing conditions for circumferential grinding. The processing mechanism 300 is the core processing component. Its sliding bracket 301 is set on the mounting frame 2 and can move laterally along the first guide rail 306 inside the sliding bracket 301 and the second guide rails 402 on both sides of the support bed 401, driving the grinding head 311 to move along the axial direction of the roll body 1 to form an axial grinding path. The first height adjustment component 302 on the sliding bracket 301 is connected to the mounting plate 304, which can drive the mounting plate 304 to rise and fall as a whole, initially adjusting the distance between the grinding head 311 and the surface of the roll body 1 to adapt to the processing requirements of rolls with different diameters; the telescopic plate 305 slidably connected to the inner side of the mounting plate 304 can extend and retract along the length of the mounting plate 304 to further fine-tune the radial processing range of the grinding head 311, ensuring that the grinding head 311 can cover the curved surface profile of the roll anti-convexity design.

The second height adjustment component 309 is connected to the first mounting shell 310 and can drive the first mounting shell 310 to perform micron-level height fine adjustment. The grinding head 311 is set inside the first mounting shell 310, which ultimately achieves precise control of the height of the grinding head 311. At the same time, the height control box 307 on the telescopic plate 305 can preset and adjust the height adjustment parameters in real time to ensure that the movement trajectory of the grinding head 311 is precisely matched with the anti-convexity design contour of the roll body 1. Through the synergistic effect of lateral movement and height adjustment, a preset curved surface is processed on the surface of the rotating roll body 1. The cooling mechanism 400 works in conjunction with the processing mechanism 300 to cool down the grinding process. The water outlet 407 at the end of the support bed 401 is used to discharge the cooling water that has completed heat dissipation. The second mounting housing 312, which is sleeved on the outside of the first mounting housing 310, is provided with a cooling water nozzle 313. The cooling water nozzle 313 faces the contact area between the grinding head 311 and the roll body 1, and can directly spray cooling water onto the heat source to quickly remove the grinding heat. The guide plate 314 at the bottom of the second mounting housing 312 can guide the flow direction of the cooling water to ensure that the cooling water fully contacts the heat dissipation area.The support bed 401 has a first cooling water channel 403 and a second cooling water channel 404 inside. The first cooling water channel 403 is located below the roll body 1, and the second cooling water channel 404 is parallel to the second guide rail 402 and is set on both sides of the support bed 401. The support bed 401 also has a third cooling water channel 405 and a fourth cooling water channel 406 at both ends, which are connected to the first cooling water channel 403 and the second cooling water channel 404 respectively, forming a comprehensive cooling channel network. The water storage tank 303, which is adjacent to the height control box 307, is connected to the cooling water nozzle 313 and each cooling water channel through pipes to continuously provide cooling water. Ultimately, it can achieve comprehensive cooling of the grinding area, the roll body 1 and the support bed 401, avoid the heat of grinding from causing the roll to deform, and ensure the processing accuracy.
