Abstract

The invention discloses a neodymium iron boron vacuum sintering furnace which comprises a furnace body, a vacuum pump, a sweeping device, a cooling device, a heating device and a containing device. Abaffle is transversely arranged in the furnace body and divides the interior of the furnace body into two spaces including a sintering cavity and a cooling cavity, the sweeping device and the heatingdevice are both arranged in the sintering cavity, the cooling device is arranged in the cooling cavity, the containing device is connected to the inner wall of the right side of the furnace body in sliding and clamped modes, a driving device is arranged on the containing device, the sintering cavity and the cooling cavity are each provided with a furnace cover, the furnace covers are connected tothe furnace body in a pivoted mode, and the vacuum pump is connected with the sintering cavity and the cooling cavity through air pipes. According to the neodymium iron boron vacuum sintering furnace,neodymium iron boron can be sintered in the sintering cavity and cooled in the cooling cavity, cooling and sintering are carried out separately, a large amount of energy is saved, the working efficiency of sintering and cooling procedures can be improved, neodymium iron boron residual substances in the sintering cavity can be automatically swept through the sweeping device, and a large amount oflabor cost is saved.

Description

technical field [0001] The invention relates to the technical field of sintering furnaces, in particular to an NdFeB vacuum sintering furnace. Background technique [0002] Sintered NdFeB permanent magnet materials have very high magnetic properties. They are used in the field of motors and have a very good energy-saving effect. At the same time, they can reduce the size of the motor. At present, sintered NdFeB permanent magnet materials have become an important supporting basis for energy-saving technology It has become an irreplaceable functional material for micro motors, and has been widely used in home appliances, automobiles, computers, communications, medical, aerospace, military and other fields. Based on its excellent magnetic properties and the needs of modern industrial development, sintered NdFeB has developed very rapidly, especially the motors using sintered NdFeB have high energy efficiency, and the development and application of sintered NdFeB permanent magne...
