Description

technical field [0001] The invention relates to the technical field of NdFeB processing, in particular to a processing device for sintered NdFeB magnetic materials. Background technique [0002] NdFeB permanent magnet material is a permanent magnet material based on the intermetallic compound ND2FE14B. The main components are rare earth, iron and boron. The sintered NdFeB permanent magnet material adopts the powder metallurgy process. Before production and processing, the sintered NdFeB permanent magnet material needs to be crushed to obtain fine powder. Generally, a jet mill is used for crushing, and the raw materials are added to the vacuum melting furnace according to the specified mass fraction, and the belt is thrown after high-temperature melting; The alloy flakes are first crushed in a hydrogenation furnace, and then made into fine powder in a jet mill; the fine powder is pressed under the protection of nitrogen to obtain a blank; the pressed blank is put into a vac...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to provide a processing device for sintered NdFeB magnetic materials, one of which is to have a material melter, a fixed melting accelerator box, a melting accelerator injector, a high-temperature production table, and a melting injector , to solve the problem that the existing processing device cannot quickly melt the material when it is in use, which makes the equipment work inefficient and consumes a long time; another purpose is to solve the problem that most of the existing processing device is in use. The equipment has only one shape and cannot shape the material in different shapes. It has the effect of enabling the device to shape the material in different shapes and improving the production capacity of the equipment. Another purpose is to have a cooling shaper , Cooler fixed table, high-efficiency cooler, and cold air injector are convenient to solve the problem that most of the existing processing devices cannot quickly cool the hot NdFeB magnets when they are in use, and it takes time to waste time after taking them out. The problem of cooling is conducive to rapid cooling of the hot junction NdFeB magnetic material, avoiding unnecessary time spent on cooling the parts when taking it out, and improving work efficiency
