Description

Technical Field

[0001] The utility model relates to an aluminum-lithium alloy, in particular to a cooling device for spray-formed aluminum-lithium alloy. Background Art

[0002] Lithium is the lightest metal element in the world. When lithium is added to aluminum as an alloying element, an aluminum-lithium alloy is formed. After adding lithium, the specific gravity of the alloy can be reduced, the rigidity can be increased, and at the same time, high strength, good corrosion resistance and fatigue resistance, and suitable ductility can be maintained. Spray forming is a process in which a high-pressure inert gas is used to atomize the alloy liquid flow into fine molten droplets, which fly and cool under high-speed airflow and are deposited into a blank before they are completely solidified. It has various advantages of rapid solidification technology, such as fine grains of the obtained material, uniform structure, and the ability to suppress macro-segregation. When cooling the spray-formed aluminum-lithium alloy, a cooling device for spray-formed aluminum-lithium alloy is required.

[0003] In the prior art, the existing cooling device for spray-formed aluminum-lithium alloy generally uses gas and water for cooling when in use, wherein the water is transported by a pump and the gas is transported by a fan. Since the ambient temperature is relatively high when cooling the spray-formed aluminum-lithium alloy, the wind transported by the fan is hot wind, which greatly reduces the cooling effect of the spray-formed aluminum-lithium alloy. Moreover, after cooling, it is not convenient to collect liquid water, resulting in water flowing and causing waste. Now, a cooling device for spray-formed aluminum-lithium alloy is urgently needed to solve the above problems. Utility Model Content

When the aluminum-lithium alloy is conveyed to the inside of the inverted U-shaped plate 3, the water pump 9 is operated to deliver the cold water source external to the water pipe 6 to the inside of the water conveying plate 5. At the same time, the fan 8 is operated to deliver the gas to the inside of the air guide plate 7 and discharge it from the blowing pipe 18. The blowing pipe 18 penetrates the water conveying plate 5 and is inserted into the inverted U-shaped plate 3, so that the cold water inside the water conveying plate 5 cools the gas inside the exhaust pipe, so that the cooled gas blows cold air to cool the aluminum-lithium alloy. The cold water is sprayed from the water spraying plate 2 along the connecting pipe 4 to spray water to cool the aluminum-lithium alloy, which facilitates the cooling of the aluminum-lithium alloy and enhances the cooling effect.

[0026] Reference Figure 1 and Figure 2 A plurality of first nozzles 10 are arranged on the inner walls on both sides of the opposite sides of the inverted U-shaped plate 3, the first nozzle 10 is connected to the water spray plate 2, and a second nozzle 181 is arranged at the bottom of the blowing pipe 18. This design uses the first nozzle 10 to facilitate the spraying of cold water liquid inside the water spray plate 2 to cool the aluminum-lithium alloy. In order to control the flow rate of the water sprayed by the first nozzle 10, a valve can be set to control and adjust it according to needs. By using the second nozzle 181, the gas from the blowing pipe 18 can be sprayed to cool the aluminum-lithium alloy.

[0027] Reference Figure 2The blowing pipe 18 is respectively provided with sealing rings 182 at the connection places with the water conveying plate 5 and the inverted U-shaped plate 3. The design improves the sealing performance of the connection by using the sealing ring 182.

An inclined surface 102 is provided between the inner wall of the roller conveyor 1 and the top wall of the roller conveyor 1. The design facilitates the avoidance of the aluminum-lithium alloy by using the avoidance groove 11, thereby avoiding the interference between the aluminum-lithium alloy conveyed by the roller conveyor 1 and the first nozzle 10. By using the inclined surface 102, the liquid can flow into the water receiving box 12 along the inner wall of the roller conveyor 1.

[0028] Reference Figure 1 A water receiving box 12 is provided at the bottom of the roller conveyor 1. The length of the inverted U-shaped plate 3 is smaller than the length of the water receiving box 12. The width of the water receiving box 12 is the same as the width of the roller conveyor 1. This design directly connects the top of the water receiving box 12 with the bottom of the roller conveyor 1, thereby facilitating the direct collection of liquid from the inside of the inverted U-shaped plate 3 to avoid waste caused by the flow of liquid.

[0029] Reference Figure 1 and Figure 3 A liquid level sensor 14 and a PLC controller 13 are provided on the side wall of the water receiving tank 12.

This design facilitates the detection of the height of the liquid inside the water receiving tank 12 by using the liquid level sensor 14. When liquid is detected, a signal is sent to the PLC controller 13. The PLC controller 13 controls the drain valve 16 to open, so that the collected liquid is discharged to a suitable position through the drain valve 16 to prevent the liquid from overflowing from the water receiving tank 12.

[0030] Reference Figure 3 A plurality of exhaust holes 17 are provided on the opposite side walls of the water receiving box 12 and are placed above the liquid level sensor 14. A waterproof breathable membrane 19 is embedded in the inner wall of the water receiving box 12 for shielding the exhaust holes 17. This design facilitates the discharge of gas entering the water receiving box 12 by using the exhaust holes 17. Under the action of the waterproof breathable membrane 19, gas can pass through to prevent liquid from flowing out.

[0031] Reference Figure 1 and Figure 3 Extension plates 121 are provided on the opposite side walls of the water receiving box 12, and fixing bolts 1211 are provided between the extension plate 121 and the roller conveyor 1. This design facilitates the connection between the water receiving box 12 and the roller conveyor 1 and improves the stability of the connection.

[0032] Reference Figure 1-Figure 3As an embodiment of the utility model: when the injection-formed aluminum-lithium alloy needs to be cooled, the staff places the aluminum-lithium alloy on the roller conveyor 1 through a manipulator, and then the roller conveyor 1 works to convey the aluminum-lithium alloy. When the aluminum-lithium alloy is conveyed to the inside of the inverted U-shaped plate 3, the water delivery pump 9 is operated to deliver the cold water source connected to the water delivery pipe 6 to the inside of the water delivery plate 5, and at the same time, the fan 8 is operated to deliver the gas to the inside of the air guide plate 7 and discharge it from the multiple second nozzles 181 on the blowing pipe 18. Since the blowing pipe 18 penetrates the water delivery plate 5 and is inserted into the inside of the inverted U-shaped plate 3, the water delivery plate 5 The internal cold water cools the gas inside the exhaust pipe, so that the cooled gas is discharged from the second nozzle 181 to blow cold air to cool the aluminum-lithium alloy. The cold water is sprayed from the first nozzle 10 on the water spray plate 2 along the connecting pipe 4 to spray water to cool the aluminum-lithium alloy, which facilitates the cooling of the aluminum-lithium alloy and enhances the cooling effect. While the cold air is blowing and cooling the aluminum-lithium alloy, it helps the liquid on the surface of the aluminum-lithium alloy to flow downward, speeding up the flow of the cooled liquid in the aluminum-lithium alloy, so that new cold water continues to exist on the surface of the aluminum-lithium alloy, further enhancing the cooling effect on the aluminum-lithium alloy.

[0033] When it is necessary to collect the cooled liquid, since the top of the water receiving box 12 is directly connected to the bottom of the roller conveyor 1 and is placed directly below the inverted U-shaped plate 3, it is convenient to directly collect the liquid from the inside of the inverted U-shaped plate 3 to avoid waste caused by the flow of liquid. When the liquid level sensor 14 detects the liquid, it sends a signal to the PLC controller 13, and the PLC controller 13 controls the drain valve 16 to open, so that the collected liquid is discharged to a suitable position through the drain valve 16, avoiding the liquid from overflowing the water receiving box 12, thereby improving the practicality of the utility model.
