Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, in particular to an isostatic pressing charging device for neodymium iron boron. Background Art

[0002] The traditional production process of neodymium iron boron magnets includes smelting process, forming process, sintering process (including isostatic pressing), etc. The working principle of isostatic pressing is Pascal's principle: the pressure of the medium (liquid or gas) in a closed container can be evenly transmitted in all directions. After the product to be pressed is loaded into the equipment, the product is subjected to equal ultra-high pressure in all directions, increasing the product density. The shrinkage of the compact depends on the compressibility of the material and the magnitude of the pressure during pressing.

[0003] The isostatic pressing work includes: putting the blank products produced in the forming process into the isostatic pressing charging device one by one. Using water as the medium, after the product to be pressed is loaded into the cold isostatic press, the product density is increased, and some defects in the sintering process of the product are reduced. In the actual production process, the isostatic pressing operator needs to put the formed products into the isostatic pressing device one by one. When the daily production volume is large, this working method not only has a high working intensity, but also causes poor product edge chipping during the placement and transfer process, with a low qualified rate and product waste.
