[0002] Aluminum rod production is a complex process involving multiple technological steps, from raw material smelting to forming and processing. It mainly uses aluminum ingots or recycled aluminum scrap, adds alloying elements to adjust properties, cleans oil and impurities from the surface of aluminum ingots, and sorts, crushes, cleans, and removes coatings from recycled aluminum. It uses gas furnaces or electromagnetic induction furnaces, with the temperature controlled at 700-760℃, adds alloying elements according to the target composition, introduces inert gas (argon) or uses refining agents (such as chlorides) to remove hydrogen and oxides from the melt, and cools and shapes the molten aluminum through a crystallizer to form round or rectangular aluminum rods.

[0003] In the existing technology, the aluminum rod production process requires melting aluminum material before casting to form aluminum rods. Before casting, the forming quality of the aluminum rods needs to be ensured based on the actual casting volume. Therefore, it is necessary to quantitatively control the amount of molten aluminum used. Based on this problem, we propose a quantitative feeding device for molten aluminum in aluminum rod production. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, a lifting device, a feeding device, and a triggering device work together. This device is installed at the aluminum rod casting production equipment. The molten aluminum storage tank is used to store molten aluminum. The tail end of the feeding plate corresponds to the mold position that can be cast. After molten aluminum is added to the storage tank, it will cause a spring on one side to stretch. The device plate with the initial position set is set on the lower side of the connecting column. When the falling connecting column triggers the control switch on the corresponding device plate, the electromagnet column will attract the connecting column. At the same time, the hydraulic rod on one side will move with the sealing plate, thereby opening the opening for feeding and casting operations. When the molten aluminum is completely poured out, the corresponding electromagnet column will be de-energized and detach from the connecting column, allowing the molten aluminum storage tank to return to its original position. After the corresponding control switch is no longer triggered, the hydraulic rod will return with the sealing plate to its original position, thus starting the next round of feeding and casting operations. The overall design of the equipment is simple and can effectively realize the quantitative addition of molten aluminum, which is worth promoting. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-2 A quantitative feeding device for molten aluminum in aluminum rod production includes a molten aluminum storage tank 1, which has good corrosion resistance and high strength. The outer wall of the molten aluminum storage tank 1 is covered with a heat-insulating material, which is a ceramic fiber composite material, to effectively maintain the temperature of the molten aluminum and prevent heat loss. A sliding column 15 is provided on the side wall of the molten aluminum storage tank 1. The sliding column 15 has a chrome-plated surface treatment and excellent wear resistance. A connecting frame 6 is fixedly connected to the upper end of the sliding column 15. The connecting frame 6 is a welded structure to ensure the connection strength and stability of the overall device. The device can be connected to existing aluminum casting equipment. The side wall of the aluminum storage tank 1 is connected to the slide column 15 through a lifting device. The lifting device includes a connecting column 8 fixedly connected to the side wall of the aluminum storage tank 1. The connecting column 8 is precision machined to ensure smooth sliding. The connecting column 8 is slidably connected to the side wall of the slide column 15. The sliding connection part uses a self-lubricating bearing to reduce frictional resistance. A spring 7 is sleeved on the side wall of the slide column 15. The spring 7 is made of high-strength spring steel and has a stable elastic coefficient.

[0019] The aluminum molten storage tank 1 has an opening through its side wall, with rounded edges to prevent splashing. A feeding device is fixedly connected to the opening, designed to ensure accurate aluminum feeding. The feeding device includes a feeding plate 5 fixedly connected to the opening of the aluminum molten storage tank 1. The feeding trough on the feeding plate 5 is conical for easy casting. A fixing frame 2 is fixedly connected to the outer side wall of the aluminum molten storage tank 1 at the corresponding position. The fixing frame 2 is bolted for easy maintenance. A hydraulic rod 3 is fixedly connected to the fixing frame 2. The hydraulic rod 3 has an IP67 protection rating and is suitable for high-temperature working environments. A sealing plate 4 is fixedly connected to the extended end of the hydraulic rod 3. The sealing plate 4 is made of high-temperature resistant graphite material. The position of the sealing plate 4 corresponds to the position of the opening to form a complete sealing system.

[0020] Specifically, a triggering device is fixedly connected to the lower end of the sliding column 15 at the corresponding position. The triggering device can automatically sense changes in the position of the storage box. The triggering device includes a tailstock 13 fixedly connected to the lower end of the sliding column 15. The tailstock 13 is a cast iron part with sufficient structural strength. An adjusting screw 12 is rotatably connected through the side wall of the tailstock 13. The adjusting screw 12 adopts a trapezoidal thread design to ensure transmission accuracy. A device plate 10 is slidably connected to the side wall of the sliding column 15 at the corresponding position. The device plate 10 is provided with a guide groove to ensure linear movement. A threaded groove is provided through the side wall of the device plate 10, and a copper nut is embedded in the threaded groove to improve wear resistance. The adjusting screw... 12 threaded connections are formed in the threaded groove to create a precision screw drive mechanism. Control switch 9 and electromagnet column 14 are fixedly connected to the side wall of device plate 10. Control switch 9 is a push-to-trigger switch and is closed when no external force is applied. Control switch 9 and hydraulic rod 3 are electrically connected and shielded cable is used to resist electromagnetic interference. Control switch 9 and electromagnet column 14 are both located directly below connecting column 8. When connecting column 8 falls, it can trigger control switch 9 and make contact with electromagnet column 14. The power supply device of electromagnet column 14 is located inside device plate 10 and is timed by a relevant controller in the prior art.

[0021] It is worth mentioning that a scale bar 11 is provided on the side wall of the sliding column 15. The scale bar 11 is made by laser etching process, which makes the reading clear and durable. The position of the scale bar 11 corresponds to the position of the device plate 10, which makes it convenient for operators to make precise parameter observation and adjustment.

[0022] In this invention, after molten aluminum is added to the molten aluminum storage tank 1, the spring 7 on one side will be stretched and deformed, gradually moving closer to the lower device plate 10. The position of the device plate 10 can be adjusted by rotating the adjusting screw 12. The position of the device plate 10 determines the amount of molten aluminum stored. When the falling connecting column 8 triggers the corresponding control switch 9 on the device plate 10, the electromagnet column 14 on one side will attract the connecting column 8, thereby fixing the position of the molten aluminum storage tank 1. At the same time, the hydraulic rod 3 on one side will move the sealing plate 14 upward under the control of the control switch 9, thereby opening the opening for the pouring and casting operation. When the molten aluminum is completely poured out, the corresponding electromagnet column 14 will be de-energized and detached from the connecting column 8 under the control of the relevant controller in the prior art, allowing the molten aluminum storage tank 1 to return to its original position. After the corresponding control switch 9 is no longer triggered, the hydraulic rod 3 can return to its original position with the sealing plate 4, thereby starting the next round of pouring and casting operation.
