Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron alloy processing technology, specifically to a device for melting and casting copper rolls of neodymium iron boron alloy. Background Technology

[0002] Neodymium iron boron alloy processing refers to the process of producing high-performance magnetic materials from elements such as neodymium, iron, and boron through a series of technological steps. In the smelting process of making neodymium iron boron alloy sheets, smelting and casting rapidly solidified wafers are key steps in the production of high-quality sintered neodymium iron boron magnets.

[0003] A search revealed that the announcement number CN214263817U, entitled "A Neodymium Iron Boron Casting Alloy Preparation Device," includes a machine body containing a feeding hopper, a condensing copper roller, and a stirring mechanism. Research and analysis revealed that although the coolant entering the condensing copper roller first contacts the middle of the cylinder to concentrate heat dissipation in the middle before flowing to both ends of the cylinder, thus maintaining a consistent surface temperature of the condensing copper roller and improving the quality of the produced Neodymium Iron Boron castings, it still has the following drawbacks to some extent.

[0004] For example, due to the large gap between the guide box and the inner wall of the roller, the coolant flow rate of the condensing copper roller in the above device is slow during operation, which affects the cooling efficiency of the copper roller and is uneven, ultimately affecting the service life of the copper roller and production efficiency. In order to solve the above technical problems, we have designed a neodymium iron boron alloy melting copper roller casting device. Utility Model Content

[0005] The purpose of this invention is to provide a copper roller casting device for melting NdFeB alloy, which has the ability to cool the copper roller more quickly, evenly and comprehensively, extend the service life of the copper roller, improve production efficiency and quality, and can quickly discharge the coolant after heat exchange. It solves the problems of low and uneven heat exchange efficiency between the coolant and the inner wall of the copper roller, and short service life of the copper roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper roller casting device for melting NdFeB alloy, comprising a copper roller body, a right cover plate connected to the right side of the copper roller body by bolts, a water jacket shell welded to the inner side of the right cover plate, an installation partition plate welded to the inner cavity of the water jacket shell, a water distribution end cap connected to the left side of the installation partition plate by bolts, a water supply shaft inner sleeve installed on the right side of the inner cavity of the water distribution end cap, a water outlet opened on the right side of the inner cavity of the water jacket shell, an adjusting bolt threaded through the left side of the inner cavity of the water jacket shell, a water supply shaft outer sleeve inserted into the inner cavity of the right cover plate, a left cover plate connected to the left side of the copper roller body by bolts, and a guide block fixedly connected to the inner side of the left cover plate.

[0007] Preferably, the copper roller body includes a roller body, and mounting grooves are provided on both the left and right sides of the roller body, and threaded grooves are provided on the inner side of the inner cavity of the mounting groove.

[0008] Preferably, a transmission wheel is fixedly fitted onto the surface of the water supply shaft sleeve, and a support base is mounted on the surface of the water supply shaft sleeve via a bearing.

[0009] Preferably, the right side of the inner sleeve of the water supply shaft extends into the inner cavity of the outer sleeve of the water supply shaft, and a small water flow gap is provided between the inner cavity of the copper roller body and the water jacket shell.

[0010] Preferably, a locking nut is threaded on the left side of the outer surface of the water supply shaft sleeve, and a washer is fitted between the locking nut and the right cover plate.

[0011] Preferably, sealing gaskets are installed between the inner sides of the left and right cover plates and the left and right sides of the copper roller body, and the number of water outlets is several, arranged at equal intervals.

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

[0013] The coolant flows through the inner sleeve of the water supply shaft to the left side of the mounting plate and into the water flow slot. Because the water flow slot is small, the coolant can quickly fill the entire water flow slot and fully contact the inner wall of the copper roller body. This makes the cooling of the copper roller body faster and more uniform, effectively improving production quality and efficiency.

[0014] The small gap between the water flow slots accelerates the flow of coolant within the slots, allowing it to quickly flow into the space to the right of the mounting baffle and be discharged through the outer sleeve of the water supply shaft. This speeds up the flow rate of the coolant after heat exchange, preventing it from prolonged contact with the inner wall of the copper roller body and effectively improving cooling efficiency.

[0015] By setting up a flow guide block, the cooling water injected into the inner sleeve of the water supply shaft can be diverted, allowing it to flow quickly and evenly into the water flow gap. At the same time, it avoids the impact force acting directly on the left cover plate, which would reduce the flow rate of the coolant and cause turbulence. Attached Figure Description

[0020] Please see Figures 1-3 A copper roller casting device for melting NdFeB alloy includes a copper roller body 1. A right cover plate 14 is bolted to the right side of the copper roller body 1. A water jacket shell 10 is welded to the inner side of the right cover plate 14. An installation partition 11 is welded to the inner cavity of the water jacket shell 10. The installation partition 11 facilitates the separation of the low-temperature coolant and the coolant after heat exchange, preventing mixing and affecting the cooling effect. A water distribution end cap 6 is bolted to the left side of the installation partition 11. The water distribution end cap 6 facilitates the support and fixation of the left side of the water supply shaft inner sleeve 4. The water supply shaft inner sleeve 4 is installed on the right side of the inner cavity of the water distribution end cap 6. A water outlet 17 is opened on the right side of the inner cavity of the water jacket shell 10. The water outlet 17 allows for... The cooling water in the water flow gap 18 can flow into the right side space of the water jacket shell 10. The left side of the inner cavity of the water jacket shell 10 is threaded with an adjusting bolt 9. By setting the adjusting bolt 9, the size of the gap between the left side of the water jacket shell 10 and the inner wall of the copper roller body 1 can be adjusted by rotating it forward or backward. The inner cavity of the right cover plate 14 is inserted with the water supply shaft sleeve 3. The left side of the copper roller body 1 is bolted with a left cover plate 8. The inner side of the left cover plate 8 is fixedly connected with a guide block 7. By setting the guide block 7, the cooling water injected into the inner sleeve 4 of the water supply shaft can be diverted so that it flows into the water flow gap 18 quickly and evenly, while avoiding the impact force directly acting on the left cover plate 8, which would cause the coolant flow rate to decrease and turbulence to form.

[0021] Please see Figure 3 The copper roller body 1 includes a roller body 16. The roller body 16 has mounting grooves 19 on both the left and right sides. By setting the mounting grooves 19, the left cover plate 8 and the right cover plate 14 can be easily installed and placed. The inner side of the inner cavity of the mounting groove 19 has a threaded groove 15. By setting the threaded groove 15, it can be easily connected to the bolts that fix the two cover plates.

[0022] Please see Figure 1 The surface of the water supply shaft sleeve 3 is fixedly fitted with a transmission wheel 2. By setting the transmission wheel 2, it can be connected to an external drive mechanism via belt drive to drive the copper roller to rotate. The surface of the water supply shaft sleeve 3 is mounted with a support base 5 through a bearing. By setting the support base 5, the copper roller mechanism can be supported and installed.

[0023] Please see Figure 2 and Figure 3 The right side of the inner sleeve 4 of the water supply shaft extends into the inner cavity of the outer sleeve 3 of the water supply shaft, and a water flow gap 18 is provided between the inner cavity of the copper roller body 1 and the water jacket shell 10.

[0024] Please see Figure 2 A locking nut 12 is threaded on the left side of the outer surface of the water supply shaft sleeve 3. By setting the locking nut 12, the water supply shaft sleeve 3 can be installed and fixed. A pad 13 is sleeved between the locking nut 12 and the right cover plate 14.

[0025] Please see Figure 3 Sealing gaskets are installed between the inner sides of the left cover plate 8 and the right cover plate 14 and the left and right sides of the copper roller body 1. There are several outlets 17, which are arranged at equal intervals.

[0026] During use, after the copper roller body 1 rotates, the coolant flows through the inner sleeve 4 of the water supply shaft into the space on the left side of the mounting partition 11, and then flows through the opening on the left side of the water jacket 10 into the water flow slot 18. Because the space of the water flow slot 18 is small, the gap between the inner wall of the copper roller body 1 and the water jacket 10 is smaller. In this way, the coolant can quickly pass through and fill the entire interior of the water flow slot 18 and make full and comprehensive contact with the inner wall of the copper roller body 1. This makes the cooling of the copper roller body 1 faster and more uniform, effectively improving production quality and efficiency. After the coolant in the water flow slot 18 exchanges heat with the copper roller body 1, the small gap will accelerate the flow of the coolant in the water flow slot 18, allowing it to quickly flow into the space on the right side of the mounting partition 11, and finally be discharged through the outer sleeve 3 of the water supply shaft. This speeds up the flow rate of the coolant after heat exchange, preventing it from contacting the inner wall of the copper roller body 1 for a long time, effectively improving cooling efficiency.

[0027] In summary, this neodymium iron boron alloy smelting copper roller casting device, through the coordinated use of the copper roller body 1, water supply shaft outer sleeve 3, water supply shaft inner sleeve 4, water distribution end cover 6, left cover plate 8, adjusting bolt 9, water jacket shell 10, mounting partition 11 and water outlet 17, solves the problems of low and uneven heat exchange efficiency between the coolant and the inner wall of the copper roller, and short service life of the copper roller.
