Description
Technical Field
The invention relates to the technical field of neodymium iron boron processing equipment, in particular to a neodymium iron boron forming parallel press system.
Background
Sintered Nd-Fe-B is the strongest permanent magnet of modern times, it not merely has high remanence, high coercivity, high magnetic energy product, high performance-price ratio advantage, etc., and it is easy to process into various sizes, especially suitable for various high-performance, miniaturized, light electronic products. In recent years, due to the rapid development of high-technology industries represented by information industries, higher and higher requirements are put forward on the performance of the neodymium iron boron, and the production process of sintered neodymium iron boron generally comprises the process flows of raw material detection, formula, melt spinning, hydrogen breaking, coarse mixing, powder making, fine mixing, molding and sintering.
The existing forming equipment for the neodymium iron boron permanent magnet material mainly comprises a magnetic field press, an isostatic press and a magnetic field isostatic press, wherein the forming mode of the permanent magnet material comprises vertical magnetic field pressure forming, parallel magnetic field pressure forming and magnetic field isostatic press according to the relation between the magnetic field direction and the pressure direction, so the forming equipment is also divided into the magnetic field vertical press, the magnetic field parallel press and the magnetic field isostatic press. The cylindrical blank pressed by the magnetic field vertical press has a large density difference due to the fact that the direction of the magnetic field is vertical to the forming direction, stress cracking is easily caused in the sintering process, and waste products are generated. Therefore, blanks pressed by a magnetic field vertical press often need to be further processed by an isostatic press. In comparison, the magnetic field parallel press not only can enable the blank to have good density distribution and effectively reduce stress cracking, but also can make the blank with a smaller magnetic declination angle which is basically close to 0 degree. Therefore, the blank pressed by the magnetic field parallel press can be directly subjected to subsequent sintering. However, since the technical development of the magnetic field parallel press is not mature enough, the magnetic field vertical press is mainly used in the current production of neodymium iron boron.
Although a few magnetic field parallel presses are also available on the market, from the viewpoint of feedback in practical use, there are still major disadvantages: the existing magnetic field parallel press has unreasonable structure and layout, so that the whole machine is large in size, needs to occupy a large installation space, and is relatively low in machining precision.
In view of the above, there is a need for improvement of the prior art.
