Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron magnet production technology, and in particular to a neodymium iron boron sintering furnace. Background Technology

[0002] Neodymium iron boron permanent magnets have excellent magnetic properties and are widely used in electronics, power machinery, medical devices, toys, packaging, hardware machinery, aerospace and other fields. Common applications include permanent magnet motors, loudspeakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment.

[0003] Patent document CN219829516U discloses a neodymium iron boron sintering furnace, specifically including a sintering furnace, a material placement mechanism, a transmission mechanism, and a linkage mechanism. The sintering furnace has a sintering cavity inside, and a furnace door is rotatably connected to one end of the furnace. The linkage mechanism is located within the sintering cavity, with one end extending outward through the bottom of the furnace and the other end extending to the top of the sintering cavity. The material placement mechanism is mounted on the linkage mechanism, and the transmission mechanism is located at the bottom of the sintering furnace. The working end of the transmission mechanism is rotatably connected to the end of the linkage mechanism extending out of the furnace. This application uses the material placement mechanism to fix the material, preventing it from slipping during sintering. Through the cooperation between the transmission mechanism and the linkage mechanism, the material placement mechanism can rotate within the sintering furnace, resulting in more uniform sintering of the material surface and thus improving the sintering effect.

[0004] The device described above is not convenient for handling materials, requiring workers to use other tools to retrieve them, which is cumbersome. Furthermore, it is not convenient for rapid heat dissipation inside the furnace, which can easily lead to workers being burned by heat waves, posing a certain danger. Therefore, we propose a neodymium iron boron sintering furnace to solve this problem. Utility Model Content
