Abstract

The invention discloses a material charging box for bonding of a neodymium iron boron magnet, belongs to a material utilizing box for bonding of the neodymium iron boron magnet in the technical field of magnets and aims at providing the material charging box for bonding of the neodymium iron boron magnet. The material charging box comprises a material box body, a connecting shaft and a material box cover. Ventilation holes are formed in the side wall of the material box body and provided with plugs. The plugs are connected with guide rods. The guide rods are connected with the side wall of the material box body. The cylindrical face of the material box cover is attached to the arc face of the material box body. A partition plate is arranged in the material box cover and divides an inner cavity of the material box cover into a left cavity and a right cavity. The two ends of the connecting shaft penetrate the left cavity of the material box cover and then are connected with the material box body. A compression spring and a fixing base are arranged in the right cavity. One end of the compression spring is pressed on the partition plate, and the other end of the compression spring is connected with the fixing base. The fixing base is connected with an elastic rope, the other end of the elastic rope sequentially penetrates the compression spring and the partition plate and then is connected to the connecting shaft in a winding manner, and the tail end of the elastic rope and the connecting shaft are fixedly connected.

Description

technical field [0001] The invention belongs to the technical field of magnets, and relates to a neodymium-iron-boron magnet, in particular to a material box for bonding neodymium-iron-boron magnets. Background technique [0002] NdFeB magnets are permanent magnets with the strongest magnetic force so far, which are divided into bonded NdFeB magnets and sintered NdFeB magnets. Bonded NdFeB is actually injection molding, and sintered NdFeB is vacuumized and heated at high temperature. [0003] Whether it is bonded NdFeB or sintered NdFeB, a material box is usually used, and the NdFeB green body is placed in the material box, and then the cover of the material box is covered, and the material box and the NdFeB in the material box The boron green body is transported to the sintering furnace for sintering or transported to the designated position for bonding. But, the known material box overwhelming majority in the prior art comprises material box body and the material box cov...
