Description

Technical Field

[0001] This utility model relates to the technical field of rare earth permanent magnet alloy material production and manufacturing equipment, and in particular to an intermediate tundish device for neodymium iron boron strip spinning. Background Technology

[0002] Neodymium iron boron (NdFeB) is an important magnetic material with excellent magnetic properties, earning it the nickname "King of Magnets." The preparation method for NdFeB involves first adding raw materials to a melting furnace for smelting. The smelted raw materials are then poured from the crucible nozzle into the upper tundish of an intermediate ladle device, flowing to the lower tundish, and finally being cast through the outlet of the lower tundish onto rotating cooling copper rollers. Following this, the material undergoes powdering, molding, and sintering to obtain the NdFeB magnetic material. The application number is CN20211034. Patent 6862.X discloses a smelting system comprising a first preparatory chamber, a second preparatory chamber, a secondary cooling unit, a primary cooling unit, a smelting chamber, and a feeding unit. The first and second preparatory chambers are respectively connected to the smelting chamber, and the first and second preparatory chambers can generate the same vacuum environment as the smelting chamber. The feeding unit can sequentially enter the first preparatory chamber and the smelting chamber, and the primary cooling unit can sequentially enter the second preparatory chamber and the smelting chamber. The discharge end of the smelting chamber is connected to the secondary cooling unit. Regardless of whether the primary cooling unit is used for primary cooling of the alloy liquid, or whether maintenance of the primary cooling unit is required, or whether materials are added to the smelting chamber or the feeding unit is used for feeding, the vacuum level of the smelting chamber is not disrupted. Repeated evacuation of the smelting chamber is unnecessary, ensuring continuous operation of the smelting chamber and improving production efficiency.

[0003] The height of the outlet in the melting chamber of the aforementioned patent is limited, and the height of the water-cooled roller is already set. Therefore, the height of the tundish device located between the two is also limited. After casting one batch, the upper and lower tundishes need to be replaced before the next casting. Since the upper tundish is located above the lower tundish, it is difficult and time-consuming to install and remove the lower tundish. Moreover, in order to ensure the installation and removal of the lower tundish, the distance between the upper and lower tundishes must be large. First, when the alloy liquid flowing down from the upper tundish falls into the lower tundish, it is easy to splash out of the lower tundish due to the high falling height, resulting in waste of resources. Second, under the limited height, the upper tundish is shallow in order to enter the melting chamber smoothly. In order to prevent the alloy liquid from overflowing from it, the interior of the upper tundish has a rectangular cavity structure with an outlet at the bottom. However, the area around the outlet of the upper tundish is prone to accumulating alloy liquid, which also leads to waste of alloy liquid. Utility Model Content

[0004] The main purpose of this utility model is to provide an intermediate tundish device for neodymium iron boron strip spinning, which facilitates the installation and removal of the intermediate tundish, saves time and effort, avoids waste of alloy liquid, and reduces the cost of replacing the intermediate tundish.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an intermediate bag device for neodymium iron boron strip spinning, which includes a support platform and a support frame. An upper placement platform and a lower placement platform are respectively provided on the support frame. One end of the upper placement platform is rotatably mounted on the support frame. A funnel frame is connected and fixed on the upper placement platform. An upper intermediate bag is placed in the funnel frame. A lower intermediate bag is provided on the lower placement platform below the funnel frame.

[0006] Furthermore, a support shaft is vertically fixed above one end of the support frame, and one end of the upper placement platform is rotatably sleeved on the outer surface of the support shaft via a bearing.

[0007] Furthermore, a first connecting rod is horizontally fixed above the other end of the support frame, a first bushing is rotatably mounted on the first connecting rod, a first screw is fixedly mounted on the outer surface of the first bushing, a first through groove matching the first screw is opened at the other end of the upper placement platform, and a first wing nut is screwed onto the first screw above the upper placement platform.

[0008] Furthermore, the bottom outlet of the upper intermediate package is a strip-shaped hole, and the side walls on both sides of the strip-shaped hole are inclined.

[0009] Furthermore, two connecting plates are fixed on the lower surface of the lower placement platform. The two ends of the two connecting plates are respectively fixed on the support frames on both sides. A second connecting rod is horizontally fixed between the two connecting plates at both ends of the lower placement platform. A second bushing is rotatably mounted on the second connecting rod. A second screw is fixed on the outer surface of the second bushing. A second through groove matching the second screw is opened on the fixing plates at both ends of the lower intermediate rim. A second wing nut is screwed onto the second screw above the fixing plate.

[0010] This utility model has the following beneficial effects: This utility model has a simple structure and is easy to implement. By rotating the upper placement platform onto the support frame, it is convenient to install and remove the intermediate ladle, saving time and effort. It also reduces the distance between the upper and lower intermediate ladles, thus preventing the alloy liquid from splashing out of the lower intermediate ladle during the fall and avoiding waste of resources. At the same time, it provides sufficient space for the upper intermediate ladle, so that the inner cavity of the upper intermediate ladle is inclined while ensuring that the alloy liquid does not overflow, thus avoiding the problem of alloy liquid accumulation and waste. In addition, the upper intermediate ladle can be reused, and only the lower intermediate ladle needs to be replaced each time, reducing the cost of replacing the upper intermediate ladle.
