[0004] In existing technologies, after some aluminum alloy wheel hubs are cast, the internal metal is in a high-temperature liquid or semi-liquid state, resulting in uneven heat distribution. Without a cooling device, the wheel hub will generate significant thermal stress during natural cooling due to varying cooling rates in different areas.

When the thermal stress exceeds the strength limit of the aluminum alloy, cracks will form inside the wheel hub, severely affecting its mechanical properties, reducing its load-bearing capacity, and posing safety hazards during use. Therefore, a cooling device for cast aluminum alloy wheel hubs is proposed to address these problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3This utility model provides an embodiment of a cooling device for cast aluminum alloy wheel hubs, including a support block 1. The support block 1 serves as the basic support component of the entire device, providing a stable mounting position for components such as a water bucket 2, a water tank 6, and an arc-shaped pipe 5, ensuring relative stability of each component during operation and guaranteeing the normal operation of cooling and other related processes. A water bucket 2 is fixedly connected to the right side of the support block 1. The water bucket 2 is mainly used to store cooling water, providing a water source for the water pump 3. Its capacity determines the amount of water available for circulation, and its material possesses a certain degree of corrosion resistance, enabling long-term storage of cooling water. A water pump 3 is fixedly connected inside the water bucket 2. The water pump 3 is the power source for cooling water circulation. Through its drive end, it drives the pipe 4, drawing water from the water bucket 2 and transporting it to the arc-shaped pipe 5, causing the water to circulate within the device to cool the aluminum alloy wheel hub. A pipe 4 is fixedly connected to the drive end of the water pump 3. Pipe 4 plays a crucial role in water transport, accurately transferring the water pumped by the pump 3 to the arc-shaped pipe 5. Its material possesses excellent sealing and water resistance, ensuring no leakage during water transport and guaranteeing the normal operation of the cooling system. The arc-shaped pipe 5 is fixedly connected inside the support block 1. Designed in an arc shape according to the shape of the aluminum alloy wheel hub, the arc-shaped pipe 5 conforms to the surface of the hub, increasing the contact area and allowing the cooling water to more efficiently remove heat from the hub, thus improving the cooling effect. A water tank 6 is fixedly connected to the bottom of the arc-shaped pipe 5. The water tank 6 collects the water flowing from the arc-shaped pipe 5 and performs preliminary filtration of the water through an internal filter plate 7, removing impurities and ensuring water recycling, thus extending the service life of the cooling device. The filter plate 7 is also fixedly connected inside the water tank 6. Multiple slots 8 in the filter plate 7 effectively intercept larger particles of impurities in the water, preventing these impurities from entering the subsequent circulation system. A connecting pipe 9 is fixedly connected inside the water tank 6, connecting the water tank 6 and the water bucket 2, so that the water filtered by the water tank 6 can flow back into the water bucket 2, forming a complete water circulation loop, ensuring the recycling of water resources and reducing water waste. A rotating component for uniform spraying is fixedly connected to the top of the support block 1;
[0034] Reference Figure 4 , Figure 5The rotating assembly includes a support plate 10, which provides a support platform for components such as the arc-shaped inclined block 11 and the motor 12, ensuring the stability of these components during operation. It also serves as a connection and transition element in the overall structure, enabling coordinated operation of all parts. The arc-shaped inclined block 11 is fixedly connected to the left side of the support plate 10. The arc-shaped inclined block 11 not only provides a mounting base for the motor 12, but its arc-shaped structure also facilitates cooperation with the rotating disk 13, making the rotation of the rotating disk 13 smoother. Simultaneously, its internal fixed connection to the pipe 4 ensures water transmission along a specific path, guiding and constraining the overall cooling water flow. The motor 12 is fixedly connected inside the arc-shaped inclined block 11, providing rotational power to the rotating disk 13. By controlling the speed and direction of the motor 12, the movement state of the rotating disk 13 can be precisely adjusted, thereby controlling the movement of connected components and achieving multi-angle cooling of the aluminum alloy hub. A rotating disk 13 is fixedly connected to the drive end of the motor 12. Driven by the motor 12, the rotating disk 13 rotates, causing the connecting rod 14 to move. During its rotation, the rotating disk 13 changes the position of the rotating block 15 connected to the connecting rod 14, thereby adjusting the shape and position of the pipe 4 and directing cooling water to different parts of the hub for uniform cooling. A connecting rod 14 is fixedly connected to the left side of the rotating disk 13. A rotating block 15 is rotatably connected to the left side of the connecting rod 14. The rotating block 15 is tightly connected to the pipe 4 and changes its position under the action of the connecting rod 14, thus changing the direction and shape of the pipe 4. This ensures that the cooling water flow accurately covers different areas of the aluminum alloy hub, improving the comprehensiveness and effectiveness of cooling. Two fixed rods 16 are fixedly connected to the left side of the arc-shaped inclined block 11. The fixed rods 16 provide rotational support points for the connecting frame 17, allowing the connecting frame 17 to rotate flexibly around them and work in conjunction with the rotating block 15. The rotation of the connecting frame 17 further adjusts the position of the rotating block 15 and the pipe 4, enhancing the cooling device's ability to control the cooling position of the hub. Two fixed rods 16 are rotatably connected to a connecting frame 17 on their adjacent sides. The connecting frame 17 connects the fixed rods 16 and the rotating block 15. Through its own rotation, it transmits motion and force between the fixed rods 16 and the rotating block 15. In conjunction with other components, the rotating block 15 can be finely adjusted in multiple directions, so that the cooling water flow can better adapt to the shape of the wheel hub and the cooling requirements.
[0035] Reference Figures 3 to 5The support block 1 is internally fixedly connected to the outside of the connecting pipe 9. The right side of the connecting pipe 9 is fixedly connected to the inside of the water tank 2. The support block 1 is internally fixedly connected to the outside of the water tank 6. This fixed connection ensures that the water tank 6 is in a stable installation position within the entire device structure, providing a reliable foundation environment for filtration and other operations within the water tank 6. The filter plate 7 has multiple slots 8 inside. The filter plate 7 prevents impurities from entering subsequent pipes 4 and water pumps 3, thus ensuring the normal operation of the cooling system and extending the equipment's service life. The left side of the arc-shaped inclined block 11 is rotatably connected to the right side of the rotating disk 13. The arc-shaped inclined block 11 is internally fixedly connected to the inside of the pipe 4. When the rotating disk 13 rotates, it drives the connected rod 14 to move, thereby causing the rotating block 15 to shift. Since the rotating block 15 is internally fixedly connected to the outside of the pipe 4... The rotating block 15 is internally fixedly connected to the outside of the pipe 4. Two connecting columns are fixedly connected to the adjacent sides of the two connecting brackets 17. The synergistic effect between the connecting brackets 17 and the rotating block 15 further enhances the cooling device's ability to precisely control the cooling position of the wheel hub, better adapting to the cooling needs of aluminum alloy wheel hubs of different shapes and sizes. The adjacent sides of the two connecting columns are rotatably connected to the distant sides of the rotating block 15, ensuring that the cooling water flow can accurately cover different areas of the aluminum alloy wheel hub, improving the comprehensiveness and effectiveness of cooling. A connecting block 19 is fixedly connected to the top of the support block 1. The connecting block 19 is fixed to the top of the support block 1, serving to connect the support block 1 and the push rod 20, providing a stable support point for the push rod 20, allowing the push rod 20 to reciprocate on its foundation. Two push rods 20 are fixedly connected to the right side of the connecting block 19. These push rods 20, connected to the connecting block 19 and the support plate 10, can extend and retract under power, pushing the mold clamping block to clamp and fix the aluminum alloy wheel hub. This ensures the stability of the wheel hub's position during cooling and stamping, preventing displacement that could affect processing quality. Two more push rods 20 are fixedly connected to the left side of the support plate 10. Two mold clamping blocks 21 are fixedly connected to adjacent sides of the multiple push rods 20. The mold clamping blocks 21 directly contact the aluminum alloy wheel hub and clamp it under the drive of the push rods 20. Their surface shape and material are specially designed to firmly clamp the wheel hub without damaging its surface, ensuring the stability and integrity of the wheel hub during processing. Multiple sliding columns 22 are fixedly connected to the top of the support block 1. Each sliding column 22 is fixedly connected to a stamping head 18. During the aluminum alloy wheel hub casting process, the stamping head 18 can perform stamping and forming operations on the wheel hub. It is fixed to the top of the support block 1 by multiple sliding columns 22. Its structure and material can withstand a large impact force, ensuring that the wheel hub can be processed into the required shape during stamping.
[0036] The working principle is as follows: First, water tank 2 stores a large amount of cooling water. Water pump 3, acting as the power source, starts, driving pipe 4 to draw water from water tank 2. The water accurately cools the aluminum alloy wheel hub through pipe 4. The arc-shaped pipe 5, through its arc-shaped structure that fits the surface of the wheel hub, efficiently carries away heat as the water flows over it. Subsequently, the water flows into water tank 6. The filter plate 7 in water tank 6 uses multiple slots 8 to intercept impurities in the water. The filtered water flows back to water tank 2 through connecting pipe 9, forming a circulation. The rotating component on the top of the support block 1 causes the cooling water to be sprayed evenly, covering different areas of the wheel hub, ensuring uniform and efficient cooling. The direction and position of the cooling water flow can be dynamically adjusted to ensure that all parts of the wheel hub receive uniform cooling, avoiding local overheating and improving the comprehensiveness and effectiveness of cooling. Uniform cooling can prevent internal stress concentration in the aluminum alloy wheel hub due to uneven cooling. During the casting process, uneven cooling can lead to quality problems such as cracks or deformation of the wheel hub. This water circulation system can greatly reduce water waste and make water resource utilization more efficient.
[0037] When motor 12 starts, its drive end drives rotating disk 13 to rotate. Rotating disk 13 drives connecting rod 14 to move, causing rotating block 15 to change position. This changes the shape and position of pipe 4 connected to it, thus adjusting the cooling water flow direction. Fixed rod 16 provides rotational support for connecting frame 17. Connecting frame 17 rotates around fixed rod 16 and transmits motion and force between fixed rod 16 and rotating block 15, further fine-tuning the position of rotating block 15 and pipe 4. Through the control of different speeds and directions of motor 12 and the coordinated action of various components, cooling water can accurately cover different areas of aluminum alloy hub, achieving a multi-angle, uniform, and efficient cooling effect. The rotating nozzle allows water to cover different angles and positions of hub, including the edge, spokes, and back of hub, which are easily overlooked, avoiding local overheating and making the temperature distribution of the entire hub more uniform. When the nozzle rotates, the water flow can continuously wash the surface of hub, allowing heat to be transferred from hub to water more quickly. Compared to static cooling, this dynamic cooling method can more effectively remove heat from the wheel hub, thereby shortening the cooling time and improving production efficiency.
