Description

Technical Field

[0001] This utility model relates to cooling technology for aluminum alloy production, specifically a water-saving cooling device for aluminum alloy production. Background Technology

[0002] Molten aluminum alloy is poured into an aluminum alloy mold from a container and solidified into an aluminum alloy workpiece. This process, also known as die casting, is the final step in aluminum alloy smelting. The qualified molten aluminum alloy produced in the smelting furnace must be cast into aluminum alloy billets of specific cross-sectional shapes and dimensions before it can be machined to obtain aluminum alloy workpieces for various applications.

[0003] Existing aluminum alloy production cooling devices are broadly classified into two categories. One type uses water cooling, which requires a large volume of flowing condensate to contact the workpiece for heat exchange. However, the condensate after heat exchange is too hot to be reused for cooling and must be discharged, resulting in high water consumption and significant water resource depletion. The other type uses air cooling. However, air cooling has a drawback when cooling aluminum alloy workpieces moving on conveyors: the surface of the workpiece in contact with the conveyor is difficult to cool directly. Even with grooves in the conveyor belt, the bottom of the workpiece cannot be adequately cooled by airflow. This necessitates moving the workpiece to a fixed position using external equipment for air cooling, followed by manual or specialized unloading after cooling. This slows down the cooling rate for large batches of aluminum alloy workpieces and increases the complexity of the cooling process. Therefore, we propose a water-saving aluminum alloy production cooling device to address these problems. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-4 As shown, a water-saving aluminum alloy production cooling device includes a body 1. The top and bottom of the body 1 are equipped with air-cooling structures 2. The air-cooling structures 2 are composed of a common combination of a fan and an air collection hood. The fan supplies air to increase the air speed, and the air collection hood guides the exhaust air. Several fans can be installed to improve the continuous cooling effect over long distances.

[0025] Conveyor 3 is symmetrically arranged on the left and right sides of the bottom inner wall of the machine body 1. The two sets of conveyors 3 have the same conveying direction. The aluminum alloy workpiece is fed from one side of the conveyor and unloaded from the other side. The conveyor belt on the surface of the conveyor 3 is a high-temperature resistant mesh chain or mesh belt to avoid being corroded by the aluminum alloy at high temperature.

[0026] The annular guide rail assembly 4 includes an annular seat 5 fixedly connected to the top inner wall of the machine body 1. Several movable seats 6 are provided on the annular seat 5. The annular guide rail assembly 4 adopts an existing mature mechanism and is driven by a motor. The movable seats 6 are connected by a belt and move. The width of the annular guide rail assembly 4 can be set to be small, and the length is tested before leaving the factory. The longest dimension is tested first. The length of the aluminum alloy workpiece under it is recorded after the temperature change during the movement reaches the set cooling value. The length of the annular guide rail assembly 4 can be designed and arranged according to this length. At the same time, in order to ensure the continuous feeding of aluminum alloy workpieces, when the annular seat 5 is installed on the annular guide rail assembly 4, the time difference between two aluminum alloy workpieces to be cooled moving to one end of the feeding conveyor 3 should be the same as or less than the time difference between two adjacent movable seats moving to one end of the conveyor 3 on that side, so as to ensure that each aluminum alloy workpiece to be cooled can be fed smoothly.

[0027] The moving assembly includes a rotating shaft 7 rotatably connected to the bottom of the moving base 6. A moving plate 8 is fixed to the bottom end of the rotating shaft 7, and a gear 9 is fixed to the outside of the rotating shaft 7. T-shaped plates 10 are symmetrically arranged on the annular base 5, and a rack 11 is fixed on the T-shaped plate 10. The rotating shaft 7 is damped and rotates at the bottom of the moving base 6 to increase the friction required for the natural rotation of the rotating shaft 7, so as to avoid its deflection in the natural state as much as possible. When the rotating shaft 7 moves with the moving base 6, when its outer gear 9 meshes with the rack 11, the gear 9 will drive the rotating shaft 7 to rotate. The length of the rack 11 should be set to allow the gear 9 to rotate 180 degrees so that the aluminum alloy workpiece on the moving plate 8 is closest to the unloading point.

[0028] In this embodiment, the unloading assembly includes a fixed arm 12 fixed to the top of the outer side of the rotating shaft 7. A motor 13 is fixed to the front side of the fixed arm 12. A swing arm 14 is rotatably connected to the output end of the motor 13. One end of the swing arm 14 is rotatably connected to the fixed arm 12. A pusher 15 is fixed inside the swing arm 14. The fixed arm 12 is used to adjust the rotation center of the swing arm 14. When the swing arm 14 rotates with the output shaft of the motor 13, it can drive the push rod 19 through the end pusher 15 to push the adjacent aluminum alloy workpiece to move one distance. When the bottom of the aluminum alloy workpiece contacts the surface of the conveyor 3, the aluminum alloy workpiece naturally moves off the moving plate 8 under the action of friction, which facilitates the unloading of the aluminum alloy workpiece.

[0029] In this embodiment, the adjustment assembly includes a fixed plate 16 fixed on the top left side of the push frame 15. A screw 17 is internally threaded onto the fixed plate 16. An adjustment plate 18 is provided at the end of the screw 17. The adjustment plate 18 is slidably connected to the top of the push frame 15. A push rod 19 is slidably connected to one end of the push frame 15. A spring 20 is fixed between the push rod 19 and the adjustment plate 18. The screw 17 can rotate to drive the adjustment plate 18 to move left and right on the surface of the push frame 15. By compressing the spring 20, the elastic force on the push rod 19 is increased, so as to adjust the pushing force according to the aluminum alloy workpieces of different masses.

[0030] In this embodiment, the movable plate 8 is provided with a number of air holes, and a slope is provided at one end of the top of the movable plate 8. The air holes facilitate the air intake area below the aluminum alloy workpiece after it is placed on the movable plate 8, so as to ensure the cooling effect of the bottom of the aluminum alloy workpiece. The slope facilitates the loading and unloading operation of the aluminum alloy workpiece from the movable plate 8.

[0031] In practical implementation, the device is connected to an external power source. The controller controls the operation of the air-cooling structure 2 and the conveyor 3. The aluminum alloy workpiece to be cooled is placed on one side of the conveyor 3. During the movement of the workpiece on the conveyor 3, a movable plate 8 remains at the end of that side of the conveyor 3. When the front end of the workpiece just contacts the movable plate 8, it continues to move upwards onto the movable plate 8 under the frictional force provided by the conveyor 3 until the frictional force is insufficient to support its continued upward movement. Then, the controller controls the annular guide rail assembly 4 to operate. The movable plate 8, carrying the aluminum alloy workpiece, moves along the annular seat 5 under the movement of the movable seat 6. When the gear 9 on the rotating shaft 7 meshes with the rack 11, the rotating shaft 7 synchronously drives the fixed arm 12 and the movable plate 8 to rotate 180 degrees, causing the movable plate 8 to... As the aluminum alloy workpiece to be cooled approaches the other side of the conveyor 3, the air-cooling structures 2 on the upper and lower sides continuously blow air onto the surface of the aluminum alloy workpiece on the moving plate 8 to accelerate its cooling speed. When the moving plate 8 carrying the aluminum alloy workpiece contacts the other side of the conveyor 3, the controller controls the motor 13 to work, which drives the pusher 15 and push rod 19 to rotate through the swing arm 14, so that the push rod 19 contacts and squeezes the cooled aluminum alloy workpiece. When the pushing force is greater than the friction between the aluminum alloy workpiece and the moving plate 8, the aluminum alloy workpiece moves off the moving plate 8. Then, driven by the forward friction of the belt on the surface of the contacting conveyor 3, it moves further down until it is completely removed, completing the loading, cooling and unloading process of a single aluminum alloy workpiece.
