Description

Technical Field

[0001] This invention relates to the field of aluminum plate processing technology, and more specifically to a precision leveling device for aluminum plate processing. Background Technology

[0002] Aluminum sheets are prone to problems such as poor flatness and uneven internal stress distribution during rolling, cutting, and stamping processes, requiring correction through leveling devices. Currently, most conventional aluminum sheet leveling equipment relies solely on multiple sets of rollers for mechanical pressing, lacking supporting structures for temperature control of the rollers and aluminum sheets, surface cleaning, and simultaneous drying. In continuous leveling operations, the rollers are prone to overheating due to friction, affecting the plasticity of the aluminum sheet. Simultaneously, aluminum shavings and impurities easily adhere to the roller surface, directly scratching the aluminum sheet. After spray cooling, the aluminum sheet cannot dry quickly, and residual liquid affects the quality of subsequent processing. Furthermore, traditional devices lack real-time cleaning mechanisms for the roller surfaces, making it difficult to consistently guarantee leveling accuracy and aluminum sheet surface quality, thus failing to meet the requirements for continuous, efficient, and high-surface-quality leveling of high-precision aluminum sheets.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Please see Figures 1-6The present invention provides a technical solution: a precision leveling device for aluminum plate processing, which is particularly suitable for continuous leveling processing of high-precision decorative aluminum plates, electronic equipment aluminum plates, and aerospace-grade aluminum plates. It can effectively eliminate defects such as bending, twisting, wave deformation, and uneven internal stress generated in the processing of aluminum plates during rolling, cutting, stamping, stretching and other processes, and achieve high-precision, high-surface-quality and high-stability leveling processing.

[0021] The overall structure of this device includes a frame 1, a feeding rack 2, a feeding assembly 3, a leveling main unit 4, a support roller group 5, a baffle 6, an intermediate roller 7, a temperature control system, a spray cooling system, an air knife drying system, an automatic roller surface cleaning system, a lateral limiting and guiding system, and an electrical control system. All systems work together to achieve fully automated operation of aluminum plates from feeding, guiding, preheating / temperature control, precision roller leveling, cooling and shaping, surface drying, roller surface cleaning, and discharge.

[0022] The frame 1 is made of thick-walled square steel pipe and steel plate welded together. After welding, it is subjected to stress-relief annealing, machining, sandblasting and rust removal, and anti-rust coating to ensure that the frame 1 has sufficient structural rigidity, strength and stability, and will not deform, vibrate or shift under long-term continuous heavy load operation, thus ensuring stable leveling accuracy.

[0023] The top surface of frame 1 is precision milled to ensure a flatness error of ≤0.05mm / m, and is used to fix and install the leveling main unit 4 and the support roller group 5. The bottom of frame 1 is equipped with adjustable support feet and anti-slip pads, which can be adjusted according to the flatness of the ground to ensure the levelness of the whole machine and avoid problems such as aluminum plate deviation and uneven roller pressure caused by the tilt of the whole machine. The side of frame 1 is equipped with inspection door, heat dissipation holes and cable trays to facilitate the layout of internal pipes and wiring and subsequent maintenance.

[0024] The support roller group 5 is fixedly installed on the top of the frame 1, located at the feed and discharge ends of the leveling host 4. The support roller group 5 consists of multiple high-precision, smooth support rollers of equal height and diameter. The support rollers are made of 40Cr alloy steel, treated with tempering, quenching, precision grinding, and chrome plating, achieving a surface hardness of HRC60-65, roundness error ≤0.005mm, and surface roughness Ra≤0.4μm. The support rollers are connected to the frame 1 via bearing seats. The bearings are high-precision double-row angular contact ball bearings, sealed with grease, resulting in low rotational resistance, long service life, and good precision retention. The function of the support roller group 5 is to provide stable support for the aluminum plate before it enters the leveling host 4 and after it leaves the leveling host 4, preventing the aluminum plate from sagging, scratching, or bumping due to its own weight, ensuring that the aluminum plate enters the leveling area in a horizontal and stable posture.

[0025] The feeding system consists of a feeding rack 2 and a feeding assembly 3, located on the left side of the leveling host 4, to achieve continuous, stable, and centered feeding of aluminum plates.

[0026] The feeding rack 2 adopts a welded profile structure, with a guide ramp and rollers at the top, facilitating manual or robotic placement of the aluminum sheet to be leveled. The rollers are made of nylon to prevent scratching the surface of the aluminum sheet. The height of the feeding rack 2 can be finely adjusted according to the thickness of the aluminum sheet and the conveying height to ensure that the feeding height of the aluminum sheet is consistent with the feeding port height of the leveling host 4.

[0027] The feeding assembly 3 is an active conveying structure, including an upper pressure roller, a lower support roller, a drive motor, a reducer, a synchronous transmission mechanism, and a pressure adjustment mechanism. The lower support roller is the active roller, driven by a servo motor and reducer, with its speed infinitely adjustable within the range of 0.5m / min to 10m / min, adapting to the leveling speed requirements of aluminum plates of different thicknesses and materials. The upper pressure roller is the driven roller, with adjustable pressure achieved through a cylinder or spring mechanism, ensuring uniform and appropriate clamping force applied to the aluminum plate, preventing slippage and indentations on the aluminum plate surface. The feeding inlet of the feeding assembly 3 is equipped with a photoelectric sensor to detect the aluminum plate's arrival signal, enabling automatic start-up and automatic shutdown of the conveying process.

[0028] Baffle 6 and hydraulic cylinder 601 form a lateral limiting and guiding system, symmetrically arranged on both sides of the aluminum plate conveying path. Baffle 6 is made of wear-resistant stainless steel plate, with polyurethane wear-resistant strips pasted on the inner side to prevent scratching the edges of the aluminum plate. Hydraulic cylinder 601 is a bidirectional miniature hydraulic cylinder, fixedly mounted on the frame 1, with the piston rod end connected to baffle 6. The hydraulic system controls the baffles 6 on both sides to move synchronously inward or outward, realizing the centering guidance and lateral limiting of aluminum plates of different widths. The stroke of hydraulic cylinder 601 can be preset, and the pressure can be adjusted to ensure that the force exerted by baffle 6 on the edge of the aluminum plate is moderate, without causing edge deformation, flaking, or other problems. During the aluminum plate conveying process, the lateral limiting system corrects the aluminum plate deviation in real time, ensuring that the aluminum plate always travels along the central axis of the device, ensuring uniform leveling force on both sides, and improving leveling accuracy and consistency.

[0029] The leveling host 4 is the core working unit of the device. It has an enclosed box structure and features dustproof, noise reduction, and safety protection functions. It integrates intermediate roller 7, retainer 701, mounting frame 703, adjusting and locking assembly 704, movable roller frame 706, cleaning roller 707 and other structures to achieve precision roll pressing and leveling of aluminum plates.

[0030] The intermediate roller 7 is the leveling actuator, with two sets symmetrically arranged along the aluminum plate conveying direction. Each set contains multiple leveling rollers arranged in an alternating pattern, forming a continuous and gradually changing roller gap. As the aluminum plate passes through the gap, it eliminates internal stress and flatness defects under repeated bending and stretching. The intermediate roller 7 is made of high-strength, high-wear-resistant, and high-thermal-conductivity alloy steel, and undergoes integral forging, heat treatment, precision centerless grinding, and surface chrome plating and polishing. The roller surface roundness and cylindricity error are ≤0.003mm, and the surface roughness Ra is ≤0.2μm, ensuring that the roller surface does not scratch the aluminum plate, does not stick to aluminum, and maintains excellent precision.

[0031] The intermediate roller 7 has an axially continuous flow channel 702 inside. The flow channel 702 has a circular or elliptical cross-section and is used to circulate the heat transfer medium, realizing the heating and cooling temperature control of the intermediate roller 7. The inner wall of the flow channel 702 is smooth and burr-free, with low flow resistance, smooth medium circulation, and ensures uniform roller surface temperature with a temperature difference ≤ ±2℃. The two ends of the intermediate roller 7 are connected to the cage 701 through high-precision bearings. The cage 701 is a cast steel or welded steel plate structure with good rigidity and high positioning accuracy. It is used to fix the position of the intermediate roller 7, ensuring the parallelism and concentricity of the roller system and avoiding problems such as jumping, offset, and jamming during operation. The mating part between the cage 701 and the intermediate roller 7 is equipped with a seal to prevent coolant and debris from entering the bearing, thus improving service life.

[0032] The clearance between the two sets of intermediate rollers 7 can be precisely adjusted according to the thickness of the aluminum plate, with an adjustment accuracy of up to 0.01mm. The adjustment method combines manual fine-tuning and electric adjustment to adapt to the leveling requirements of aluminum plates of different specifications. The clearance adjustment mechanism is equipped with a scale display and locking device, which reliably locks after adjustment to ensure stable long-term operating accuracy.

[0033] The temperature control system consists of a heating box 708, an electric heating tube 709, a cooling box 710, a heat sink 711, a cooling fan 712, and an internal flow channel 702 for the intermediate roller 7. It enables real-time and precise control of the temperature of the intermediate roller 7 and is compatible with various process modes such as hot leveling, cold leveling, and room temperature leveling.

[0034] The heating chamber 708 is fixedly installed on the front of the leveling host 4. Multiple U-shaped or straight electric heating tubes 709 are installed inside. The electric heating tubes 709 are sheathed with stainless steel, providing good insulation, high heating efficiency, and long service life. The heating chamber 708 is connected to the flow channel 702 of the intermediate roller 7 via pipelines and is filled with heat-conducting oil, water, or other heat-conducting media. When the electric heating tubes 709 are energized, they heat the heat-conducting media. Driven by a pump, the media circulates through the flow channel 702, evenly transferring heat to the surface of the intermediate roller 7, thus heating the roller. The temperature control system is equipped with a temperature sensor and a PID temperature controller, which can control the temperature of the intermediate roller 7 within the range of room temperature to 200℃, with a temperature control accuracy of ±1℃. This meets the temperature requirements for hot leveling of different grades of aluminum alloy sheets, effectively reducing the yield strength of the aluminum sheet, improving the leveling effect, and avoiding problems such as springback and cracking caused by cold leveling.

[0035] The cooling box 710 is fixedly installed on the back of the leveling host 4, forming a convection heat dissipation structure with the heating box 708. The interior of the cooling box 710 is also connected to the flow channel 702. The heat sink 711 is a high-efficiency aluminum alloy heat dissipation fin, with one end extending into the interior of the cooling box 710 to contact the heat-conducting medium, and the other end exposed to the external environment. The cooling fan 712 is a high-speed axial flow fan, fixedly installed on the side of the cooling box 710, with the airflow directed directly towards the heat sink 711. When cooling or temperature reduction is required, the electric heating tube 709 is turned off, and the cooling fan 712 is started. The heat sink 711 quickly absorbs the heat from the medium and dissipates it into the air, achieving rapid cooling, constant temperature control, or cooling and shaping of the intermediate roller 7. The cooling system can reduce the roller temperature from 200℃ to room temperature within 5 minutes, meeting the production requirements of continuous process switching.

[0036] The temperature control system is linked with the overall electrical control system. It can preset temperature curves to achieve automatic heating, automatic temperature control, automatic cooling, and automatic shutdown protection. When the temperature exceeds the limit or the sensor fails, it will automatically alarm and cut off the power supply, thus improving the safety of use.

[0037] The spray cooling and lubrication system consists of a liquid storage tank 401, a micro pump 402, an inlet pipe 403, a spray pipe 404, and a fan-shaped nozzle 405. Its main function is to cool, lubricate, and clean the aluminum plate and the intermediate roller 7, reduce roller friction, reduce aluminum adhesion, control the processing temperature, and improve surface quality.

[0038] The liquid storage tank 401 is fixedly installed on top of the leveling unit 4. It is a sealed enclosure made of stainless steel or engineering plastic, with anti-corrosion and leak-proof functions. The volume is designed from 10L to 50L depending on the model, and it is used to store coolant, rust inhibitor, or special lubricant for aluminum plates. The top of the liquid storage tank 401 is equipped with a liquid filling port, a level gauge, and a filter screen for easy observation of the liquid level and filtration of impurities. The bottom is equipped with a drain port for easy periodic liquid replacement and tank cleaning.

[0039] The micro pump 402 is a micro gear pump or diaphragm pump, fixedly installed on the top of the liquid storage tank 401. The inlet end is connected to the liquid storage tank 401 through the inlet pipe 403, and the outlet end is connected to the spray pipe 404. The micro pump 402 has stable pressure and adjustable flow rate, and the spray volume can be adjusted according to the thickness of the aluminum plate, speed and temperature to ensure cooling and lubrication effects.

[0040] The spray pipe 404 is a precision stainless steel tube, horizontally arranged along the length of the mounting frame 703 and passing through the mounting frame 703, located above the intermediate roller 7 and above the aluminum plate. Multiple fan-shaped nozzles 405 are evenly arranged on the spray pipe 404. The spray angle of the fan-shaped nozzles 405 is 60°-120°, with a wide spray coverage and uniform mist, which can fully cover the upper surface of the aluminum plate and the roller surface of the intermediate roller 7, avoiding uneven cooling in some areas.

[0041] When the spray system is working, the micro pump 402 pressurizes and delivers liquid to the spray pipe 404, which is then evenly sprayed onto the working area through the fan-shaped nozzles 405. This reduces the temperature of the aluminum plate and roller surface, preventing overheating, deformation, and aluminum adhesion; lubricates the contact surface between the roller surface and the aluminum plate, reducing frictional resistance and improving surface smoothness; washes away debris, dust, and oil from the aluminum plate surface, keeping it clean; and helps remove heat generated during leveling, improving temperature control efficiency. The spray liquid can be recycled and reused. The bottom of the device is equipped with a liquid receiving tray and a return pipeline, which filters the used liquid and returns it to the storage tank 401, reducing operating costs and meeting environmental protection requirements.

[0042] The air knife drying system consists of a fan box 406, an air duct 407, and an air knife 408. It is used to quickly blow away residual coolant, lubricant, and water stains on the surface of aluminum plates, ensuring that the aluminum plates are dry and clean when they are discharged, without any residue, which facilitates subsequent cutting, coating, packaging, and deep processing.

[0043] The fan box 406 is fixedly installed on the top of the leveling host 4. A high-pressure centrifugal fan or vortex fan is installed inside, which has high air pressure, stable air volume and low noise. The air outlet of the fan box 406 is sealed to the air duct 407. The air duct 407 is a pressure-resistant and sealed pipeline that delivers high-pressure airflow to the air knife 408.

[0044] The air knife 408 is a precision aluminum alloy air knife with an internal guide cavity and a narrow-slit air outlet. The width of the air outlet is finely adjustable to ensure uniform airflow and high air velocity. The air knife 408 is arranged at a 30° angle relative to the aluminum plate surface, with the tilt direction consistent with the aluminum plate conveying direction. This allows the airflow to sweep the aluminum plate surface at the optimal angle, effectively removing liquids without causing the aluminum plate to shake or shift.

[0045] The air knife drying system is linked to the feeding speed; the faster the aluminum plate is conveyed, the higher the fan speed, ensuring a consistently stable drying effect. After air knife drying, the surface moisture content of the aluminum plate is ≤0.1%, with no visible liquid marks, water stains, or oil residue, meeting the surface quality requirements for high-precision aluminum plates.

[0046] The automatic roller surface cleaning system consists of a mounting frame 703, an adjusting and locking assembly 704, a mounting plate 705, a movable roller frame 706, and a cleaning roller 707. It is used to remove aluminum chips, oxide scale, oil stains, coolant impurities attached to the surface of the intermediate roller 7 in real time, so as to avoid foreign objects on the roller surface scratching the aluminum plate surface and affecting the leveling accuracy, and to ensure the stability of long-term continuous production.

[0047] The mounting bracket 703 is fixedly installed inside the leveling host 4 and is a rigid support structure used to support the cleaning mechanism. The adjusting and locking assembly 704 is a high-precision screw adjustment mechanism, including an adjusting screw, a locking nut, and a guide post. It can manually or electrically adjust the front and rear positions of the mounting plate 705, thereby adjusting the contact pressure between the cleaning roller 707 and the intermediate roller 7. After adjustment, it is reliably locked to ensure stable and non-loose contact pressure.

[0048] Mounting plate 705 is fixedly connected to movable roller frame 706, which can be either swing-type or fixed. Cleaning roller 707 is installed inside through high-precision bearings. Cleaning roller 707 is made of wear-resistant, oil-resistant, non-stick aluminum polymer material or wool felt or rubber material. Its surface is soft and will not damage the surface of intermediate roller 7. It also has good adsorption and scraping capabilities.

[0049] The outer surface of the cleaning roller 707 maintains rolling contact with the outer surface of the intermediate roller 7, with moderate contact pressure. When the intermediate roller 7 rotates, the cleaning roller 707 rotates synchronously and follows suit, wiping and removing impurities from the roller surface in real time, keeping the surface of the intermediate roller 7 clean and smooth. The cleaning roller 707 has a detachable structure, which can be quickly replaced when it is worn or heavily contaminated, making maintenance convenient.

[0050] This device adopts a fully automatic electrical control system, equipped with a touch screen, PLC controller, servo drive system, sensor module, and alarm module to achieve fully automated control of the entire process.

[0051] The complete workflow is as follows: Feeding: Place the aluminum plate to be leveled on the feeding rack 2 and feed it into the feeding assembly 3 via the guide rollers; Centering guidance: Hydraulic cylinder 601 drives baffle 6 to move, centering and limiting the aluminum plate; Feeding and conveying: The feeding component 3 smoothly feeds the aluminum plate into the leveling host 4 at a set speed; Temperature control preheating: According to process requirements, the electric heating tube 709 heats the intermediate roller 7 to the set temperature; Precision leveling: The aluminum plate is repeatedly rolled and leveled between two sets of intermediate rollers 7 to eliminate deformation and internal stress; Spray cooling and lubrication: The spray system sprays water onto the aluminum plate and roller surface in real time for cooling and lubrication; Roller surface cleaning: Cleaning roller 707 simultaneously cleans the surface of intermediate roller 7 to prevent scratches from foreign objects; Air knife drying: After the aluminum plate leaves the leveling area, it is dried by the high-pressure airflow of air knife 408; Supported discharge: Supported by the 5th support roller group, the material is discharged smoothly, completing the leveling operation.

[0052] The device has safety functions such as overload protection, deviation protection, over-temperature protection, liquid shortage protection, fault alarm, and emergency shutdown to ensure the safety of operators and equipment.
