Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and in particular to a washing device for aluminum ball production. Background Technology

[0002] In the metal processing industry, aluminum balls are widely used in high-end manufacturing scenarios such as precision bearings, aerospace components, and automotive engines due to their low density, excellent electrical conductivity, and stable mechanical properties. During the production of aluminum balls, after processes such as rolling and forging, impurities such as rolling oil, metal debris, and oxide scale remain on the surface. If cleaning is not thorough, it will directly affect the uniformity of subsequent heat treatment, the adhesion of the coating, and the assembly accuracy, and may even lead to premature product failure. Therefore, the cleaning process is a critical step in ensuring the quality of aluminum ball products.

[0003] Currently, aluminum ball cleaning equipment in the industry suffers from the following technical defects, which restrict the improvement of production efficiency and product quality: Existing spraying equipment mostly uses fixed-angle nozzles, while aluminum balls have spherical or irregular shapes with natural curvature and grooves on their surfaces (such as the arc grooves of aluminum balls used in bearings). Fixed nozzles cannot adapt to the curved surface features of aluminum balls of different specifications, resulting in an oil residue rate of over 30% in the grooves, requiring secondary manual wiping. This not only increases labor costs but also leads to significant fluctuations in product qualification rates (±10%) due to the randomness of manual operation.

[0004] While some equipment integrates spraying and ultrasonic functions, it suffers from structural design flaws: the ultrasonic transducers are scattered, failing to form a 360° surround sound field, resulting in weak cleaning effects on the bottom and sides of the aluminum balls; furthermore, the spray pipes conflict with the ultrasonic transducers, and the water flow impact disrupts the stability of the cavitation field, leading to an oil removal efficiency of less than 60%, especially for high-viscosity rolling oils (kinematic viscosity ≥15 mm). 2 / s) The cleaning effect is even worse.

[0005] Existing conveyor belts are mostly planar structures, which makes the aluminum balls prone to rolling and shifting during transport, leading to misalignment of the cleaning positions. Furthermore, the conveyor belt surface lacks drainage design, causing water accumulated after cleaning to be carried into the drying process along with the aluminum balls, resulting in secondary contamination. Additionally, there is a lack of anti-slip structures for aluminum balls of different diameters (2-50mm), causing small-diameter balls to easily get stuck and large-diameter balls to easily slip off, affecting production continuity.

[0006] Traditional drying equipment typically has vertically downward or horizontally laid-out air ducts, preventing hot air from flowing tangentially along the surface of the aluminum balls. This causes water droplets to flow back into the cleaned area under gravity, resulting in a surface water residue rate of up to 15% after drying. Furthermore, the hot air distribution is uneven, with aluminum balls near the air outlet prone to oxidation and discoloration due to localized high temperatures, while those further away from the outlet are not thoroughly dried, requiring an extended drying time of 15-20 minutes, which restricts production cycle.

[0007] Existing equipment lacks online detection and intelligent control functions: it cannot automatically identify aluminum ball specifications and match cleaning parameters, requiring manual adjustment; there is no cleanliness testing step after cleaning, and substandard products can easily flow into the next process, leading to batch quality risks. Meanwhile, the wastewater collection system is poorly designed, with cleaning wastewater and drying condensate being mixed and discharged, increasing environmental treatment costs.

[0008] To address the aforementioned issues, there is an urgent need to develop a washing device that integrates dynamic spray adjustment, synergistic ultrasonic cleaning, directional high-efficiency drying, and intelligent detection functions. This device would solve the problems of incomplete cleaning, low efficiency, poor adaptability, and unstable quality in existing equipment, and meet the needs of large-scale production of high-end aluminum balls.

[0015] Preferably, the ultrasonic mechanism includes a support module, an ultrasonic transducer, a fixing block, and an ultrasonic generator; The support module is fixedly connected inside the cleaning unit and located in the middle of the conveyor belt, and a set of ultrasonic transducers is fixedly connected to the upper end of the support module.

[0018] Compared with the prior art, the beneficial effects of this utility model are: (1) The washing device for aluminum ball production, after the variable frequency speed control motor starts, drives the transmission rollers at both ends to rotate synchronously through gears and chains, and drives the conveyor belt to run at an adjustable speed of 0.5-2m / min. The aluminum ball enters the conveyor belt from the left end of the support frame. The anti-slip module on the surface prevents the aluminum ball from rolling and deviating, and the front and rear baffles prevent the aluminum ball from falling. When the aluminum ball enters the detection area with the conveyor belt, the laser detector inside the support frame scans the diameter of the aluminum ball (2-50mm) in real time. The detection data is synchronously transmitted to the control box module at the front end of the cleaning unit to provide a basis for subsequent cleaning parameter adjustment.

[0019] (2) The washing device for aluminum ball production, the control box module automatically adjusts the electromagnetic flow valve and pressure transmitter according to the laser detection results, and stabilizes the water inlet pressure of the main pipe at 0.2-0.5MPa (lower value for small diameter aluminum balls, higher value for large diameter / irregular aluminum balls). At the same time, it commands the rotating motor of the spray assembly to start, and rotates the fan-shaped nozzle to the target angle of 30°-120° through the limit block (the groove area is specifically adjusted to 30°-60°). The main pipe supplies water to each secondary pipe through the connecting pipe one. Each fan-shaped nozzle on each secondary pipe one sprays the top and curved surface of the aluminum ball. The secondary pipe one supplies water to each group of front and rear ends of each secondary pipe two through the connecting pipe two. Each group of fan-shaped nozzles on each secondary pipe two rinses from the side at an angle, forming a staggered coverage with the top nozzle to avoid water flow interference. The control box module synchronously starts the ultrasonic generator, so that the ultrasonic transducer in the cleaning unit generates a high frequency vibration of 20-40kHz. The ultrasonic transducer on the support module below the conveyor belt acts upward on the bottom of the aluminum ball.

[0020] (3) The washing device for aluminum ball production: After cleaning, the aluminum balls enter the transition zone with the conveyor belt. The residual cleaning liquid on the surface drips off through the through hole. The stamped arc on the surface of the conveyor belt guides the liquid to the water receiving tray to avoid it from entering the drying unit. After the aluminum balls enter the drying unit, the control box module starts the centrifugal fan and finned electric heater to generate hot air at 60-80℃. The hot air enters the four sets of drying pipe groups through the connection module. Each set of two air outlet pipes blows downward at a 45° angle onto the surface of the aluminum balls. The airflow flows along the tangential direction of the aluminum balls, forcing the residual water droplets to converge at the bottom. The water droplets fall into the water receiving tray through the through hole of the conveyor belt and are finally treated by the wastewater discharge tank to avoid secondary pollution.

Simultaneously, it instructs the rotary motor 27 of the spray assembly to start, rotating the fan-shaped nozzles 29 to a target angle of 30°-120° via the limit block 28 (adjusted to 30°-60° for the grooved area). Main pipe 1... 3. Water is supplied to three secondary pipes 22 through connecting pipe 1 23. The six fan-shaped nozzles 29 on each secondary pipe 22 spray the top and curved surface of the aluminum ball. The secondary pipe 22 supplies water to two sets at the front and rear ends of four secondary pipes 2 12 through connecting pipe 2 11. The two fan-shaped nozzles 29 on each set of secondary pipes 2 12 rinse from the side at an angle, forming a staggered coverage with the top nozzle to avoid water flow interference. The control box module 8 synchronously starts the ultrasonic generator 31, so that the ultrasonic transducer 25 in the cleaning unit 5 generates a high frequency vibration of 20-40kHz.

Four identical drying tube groups are fixedly connected to the output end of the finned electric heater 18. Each drying tube group consists of two identical air outlet pipes 26, and the four identical drying tube groups are located inside the drying unit 16. The cleaned aluminum balls enter the transition zone with the conveyor belt, and the surface residue... The cleaning fluid drips through the through hole 14. The stamped arc on the surface of the conveyor belt guides the liquid to the water receiving tray 19, preventing it from entering the drying unit 16. After the aluminum balls enter the drying unit 16, the control box module 8 starts the centrifugal fan 17 and the finned electric heater 18 to generate hot air at 60-80℃. The hot air enters the four sets of drying pipe groups through the connection module. Each set has two air outlet pipes 26 that blow downwards at a 45° angle onto the surface of the aluminum balls. The airflow flows along the tangential direction of the aluminum balls, forcing the residual water droplets to gather at the bottom. The water droplets fall into the water receiving tray 19 through the through hole 14 of the conveyor belt and are finally centrally treated by the sewage discharge tank 21 to avoid secondary pollution. A water receiving tray 19 is fixedly connected inside the cleaning unit 5 and the drying unit 16. The water receiving tray 19 is located at the lower end of the support module 24 and inside the conveyor belt 2. The rear end of the right end of the water receiving tray 19 is fixedly connected to the right sewage discharge tank 21.

[0028] Working principle: After the variable frequency speed control motor 6 starts, it drives the transmission rollers 7 at both ends to rotate synchronously through the gear and chain 20, which drives the conveyor belt 2 to run at an adjustable speed of 0.5-2m / min. The aluminum ball enters the conveyor belt 2 from the left end of the support frame 1. The anti-slip module 4 on the surface prevents the aluminum ball from rolling and deviating, and the front and rear baffles 3 prevent the aluminum ball from falling. When the aluminum ball enters the detection area with the conveyor belt, the laser detector 15 inside the support frame 1 scans the diameter of the aluminum ball (2-50mm) in real time. The detection data is synchronously transmitted to the control box module 8 at the front end of the cleaning unit 5 to provide a basis for subsequent cleaning parameter adjustment. Based on the laser detection results, the control box module 8 automatically adjusts the electromagnetic flow valve 10 and the pressure transmitter 9 to stabilize the inlet pressure of the main pipe 13 at 0.2-0.5 MPa (lower value for small-diameter aluminum balls, higher value for large-diameter / irregular-shaped aluminum balls). Simultaneously, it instructs the rotary motor 27 of the spray assembly to start, rotating the fan-shaped nozzles 29 to a target angle of 30°-120° via the limit block 28 (adjusted to 30°-60° for the grooved area). The main pipe 13 supplies water to three secondary pipes 22 through the connecting pipe 23. Each secondary pipe 22... The six fan-shaped nozzles 29 spray the top and curved surface of the aluminum ball. The secondary pipe 1 22 supplies water to two sets of the front and rear ends of the four secondary pipes 2 12 through the connecting pipe 2 11. The two fan-shaped nozzles 29 on each set of secondary pipes 2 12 rinse from the side at an angle, forming a staggered coverage with the top nozzle to avoid water flow interference. The control box module 8 synchronously starts the ultrasonic generator 31, so that the ultrasonic transducer 25 in the cleaning unit 5 generates a high frequency vibration of 20-40kHz. The ultrasonic transducer 25 on the support module 24 below the conveyor belt 2 acts upward on the bottom of the aluminum ball. The ultrasonic transducer 25 on the front and rear fixed blocks 30 of the cleaning unit 5 provides side-assisted vibration to form a 360° sound field coverage. The ultrasonic cavitation effect and high-pressure spray work together: first, the ultrasonic waves loosen stubborn impurities such as rolling oil, and then the fan-shaped nozzles 29 directionally flush the impurities. The impurities fall into the water receiving tray 19 through the through hole 14 of the conveyor belt 2 with the water flow. After cleaning, the aluminum balls enter the transition zone via the conveyor belt. The residual cleaning liquid on the surface drips off through the through-hole 14. The stamped arc on the surface of the conveyor belt guides the liquid to the water receiving tray 19, preventing it from being carried into the drying unit 16. After the aluminum balls enter the drying unit 16, the control box module 8 starts the centrifugal fan 17 and the finned electric heater 18 to generate hot air at 60-80℃. The hot air enters four sets of drying pipe groups through the connection module. Each set has two air outlet pipes 26 that blow downwards at a 45° angle onto the surface of the aluminum balls. The airflow flows along the tangential direction of the aluminum balls, forcing the residual water droplets to converge at the bottom. The water droplets fall into the water receiving tray 19 through the through-hole 14 of the conveyor belt and are finally centrally treated by the sewage discharge tank 21 to avoid secondary pollution. After drying, the aluminum balls enter the second inspection area. The laser detector 15 scans the surface again and analyzes the residual impurity rate through infrared spectroscopy. If the threshold is ≤0.5%, the aluminum balls are discharged from the right end of the support frame 1. If they are not qualified, the control box module 8 instructs the conveyor belt to reverse and send the aluminum balls back to the cleaning unit for reprocessing until they meet the standard.
