Abstract
Description
Technical Field
[0001] This utility model relates to an automatic casting device, and more particularly to an automatic casting device for a weight-sensing adaptive assisted vacuum rapid solidification casting furnace. Background Technology
[0002] Neodymium iron boron (NdFeB) magnets are widely used in electronic devices, the automotive industry, and wind power generation due to their high energy product and excellent coercivity. However, traditional preparation methods such as sintering (high-temperature treatment leads to grain enlargement, affecting performance) and bonding (limited magnetic properties and heat resistance) have limitations. To overcome these problems, the strip spinning method, a rapid solidification technique, is employed. This method involves attaching molten NdFeB alloy to a rotating cooling wheel for rapid cooling, forming a fine, uniform, or amorphous structure, significantly improving the material's magnetic properties.
[0003] Neodymium iron boron (NdFeB) sheets prepared by the strip casting method possess excellent magnetic properties, temperature stability, and anti-demagnetization capabilities, and can be further processed into high-performance bonded magnets or used directly. However, traditional automatic casting devices for vacuum rapid solidification furnaces rely on angle gauges and proportional valves to control the crucible tilting angle, making precise adjustments based on the real-time state of the molten steel in the tundish difficult, resulting in inconsistent product quality. Therefore, it is necessary to develop a novel automatic casting device based on weight-sensor adaptive control to improve the quality of strip-cast sheets and meet the demands of high-end products. Utility Model Content
[0004] To overcome the shortcomings of traditional casting devices, such as the inability to detect changes in the weight of molten steel in the tundish in a timely and accurate manner, unstable molten steel flow, and inconsistencies in product quality, this utility model provides a weight-sensing adaptive assisted vacuum rapid solidification casting furnace automatic casting device.

The connecting rod is rotatably connected to the stabilizer frame and is fixedly connected to the furnace. A hydraulic cylinder is installed near the furnace on the stabilizer frame. The piston rod of the hydraulic cylinder is connected to the connecting rod, and the hydraulic cylinder is electrically connected to the control cabinet.

Detailed Implementation
[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.
[0020] Example: A device for automatic casting in a weight-sensing adaptive assisted vacuum rapid solidification casting furnace, such as... Figures 1-4 As shown, the system includes a control cabinet 1, a stabilizer 2, a crucible 3, a furnace 4, an intermediate ladle 9, a gravity sensor 14, a support platform 16, and a tilting mechanism. The stabilizer 2 is located on one side of the control cabinet 1, and the tilting mechanism is mounted on the stabilizer 2. The tilting mechanism is connected to the furnace 4, and the crucible 3 is fixedly connected inside the furnace 4. The support platform 16 is fixedly connected to the side of the stabilizer 2 closest to the furnace 4. The gravity sensor 14 is installed at the center of the top of the support platform 16, and the intermediate ladle 9 is located above the support platform 16. Both furnace 4 and furnace 4 are electrically connected to control cabinet 1. Here, the tilting mechanism includes hydraulic cylinder 6 and connecting rod 7. Connecting rod 7 is rotatably connected to stabilizer 2 and fixedly connected to furnace 4. Hydraulic cylinder 6 is installed in the movable chamber of stabilizer 2 near furnace 4. The piston rod of hydraulic cylinder 6 is hinged to connecting rod 7. Hydraulic cylinder 6 is electrically connected to control cabinet 1. The piston rod of hydraulic cylinder 6 extends outward and pushes connecting rod 7 to rotate, thereby tilting furnace 4 to pour material.
[0021] like Figures 1-2 As shown, a guide plate 5 is fixedly connected to the opening of the crucible 3. Here, the guide plate 5 of the crucible 3 corresponds to the tundish 9. The function of the guide plate 5 is to provide guidance for the molten steel when the crucible 3 is poured, so that the molten steel can flow into the tundish 9 accurately, prevent the molten steel from leaking, and improve work efficiency.
[0022] like Figures 3-4 As shown, a buffer plate 8 is fixedly connected to the top of the tundish 9. The buffer plate 8 is designed to be inclined. Here, the design of the buffer plate 8 can provide guidance for the falling molten steel, prevent the molten steel from falling vertically into the tundish 9 and causing splashing, effectively improve the safety of the operation and reduce material waste.
[0023] like Figures 3-4 As shown, a flow limiting plate 10 is fixedly connected to the tundish 9. Here, the function of the flow limiting plate 10 is to limit the flow of molten steel in the tundish 9, prevent a large amount of molten steel from flowing out, ensure the uniformity and stability of the molten steel flow, and further improve the work quality.
[0024] like Figure 4As shown, a guide rod 15 is fixedly connected to the support platform 16. A lower flip plate 13 is slidably connected to the guide rod 15. An upper flip plate 11 is rotatably connected to the lower flip plate 13. The upper flip plate 11 is fixedly connected to the tundish 9, and the upper flip plate 11 and the lower flip plate 13 are fixed to each other by bolts 12. Here, the bolts 12 are loosened to release the upper flip plate 11 from the fixed state. Then, the tundish 9 is pulled, and the tundish 9 drives the upper flip plate 11 to flip, causing the tundish 9 to tilt. This allows the residual molten steel in the tundish 9 to flow out, preventing molten steel residue and effectively improving the utilization rate of resources.
[0025] This device is used for casting aluminum sheets. During operation, sufficient molten material is added to crucible 3. Then, furnace 4 is started via control cabinet 1. Furnace 4 heats crucible 3, melting the molten material inside. Control cabinet 1 then controls hydraulic cylinder 6, extending its piston rod outwards. The piston rod pushes connecting rod 7 to rotate, causing furnace 4 to tilt away from control cabinet 1. The molten steel in crucible 3 then flows through guide plate 5 to buffer plate 8. After falling onto buffer plate 8, the molten steel is guided by the inclined surface of buffer plate 8 and flows into tundish 9. The molten steel is then connected to tundish 9... The flow-limiting effect of the flow-limiting plate 10 allows the molten steel to pass through the flow-limiting plate 10 evenly and stably, and finally fall onto the casting drum for casting. When the molten steel flows to the tundish 9, the gravity sensor 14 senses the weight in the tundish 9 in real time. When the gravity sensor 14 senses that the weight of the molten steel in the tundish 9 has decreased, the gravity sensor 14 sends a signal to the control cabinet 1. After receiving the signal, the control cabinet 1 adjusts the extension length of the hydraulic cylinder 6 according to the actual situation, so that the molten steel in the crucible 3 can be poured into the tundish 9 stably and evenly, thereby ensuring the stability and smoothness of the casting work. The work is then completed.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
