Description
Technical field
The present invention relates to a kind of compaction apparatus and method, particularly a kind of compaction apparatus and method of utilizing electromagnetic driven.
Background technology
At present, the manufacturing step of general permanet magnet is by the pulverizing of magnetite raw material, orientation, pressurization, heat treatment, finally carries out sintering to complete magnetite.The action that magnetite raw material is pulverized is, utilize bruisher or pulverizer magnetite raw material meal to be broken into the size of 200 μ m left and right, then, utilize jet mill to carry out Crushing of Ultrafine in the magnetite powder of coarse crushing, be made as and there is following (for example, the micropowder of 0.1 μ m ~ 5.0 μ average grain diameter m) of specific dimensions.
The process of orientation and pressurization is that fine magnetite powder is put into mould, from outside, magnetite powder is applied to magnetic field on the one hand, must be required shape to magnetite powder extrusion forming on the other hand.
Heat treated action is, under hydrogen environment, with 200 DEG C ~ 900 DEG C, the formed body that utilizes press-powder shaping formed thereby kept to a few hours (for example 5 hours), carries out by this preheating in hydrogen.In this hydrogen in preheating, make organo-metallic compound thermal decomposition and reduce the so-called decarburization of the carbon amount in pre-burning body.Again, in hydrogen, preheating is that carbon amount in making pre-burning body does not reach 0.2wt%, is more preferred under the condition that does not reach 0.1wt% and carries out.By this, utilize sintering processes subsequently and sintering permanet magnet entirety densely, can not reduce relict flux density or coercive force.
The action of last sintering is that the formed body of preheating in hydrogen is carried out to sintering processes.Moreover, as the sintering method of formed body, except general vacuum-sintering, also can utilize and will under the state of formed body pressurization, carry out the pressure sintering etc. of sintering.
U.S. Patent Publication No. US20100310408 discloses a kind of orientation and pressue device of permanet magnet, after material powder is filled in filled chamber, carries out magnetic field orientation in magnetic field.Now, for the material powder in filled chamber, for example, from the direction identical with the filling direction of the material powder for filled type, pushing means are done to pushing with specific pressure and adhered to.In this, these pushing means and material powder between the area of contact-making surface (pushing face), because being is set to compared with the cross sectional area of filled chamber as less, therefore, adhere to if pushing means are done to pushing for material powder, the space Raw powder between pushing means and filled chamber inner side is to be urged to retreat.Then, in the combination of the crystallization plane of fracture in the alignment direction of magnetic field, the chance that the crystallization plane of fracture with more equal crystal orientation relation is done to combine becomes many, once and if there is the crystallization plane of fracture combination of equal crystal orientation relation, can form strong marriage chain, utilize this, in the alignment direction of magnetic field, be engaged and unanimously crystallization plane of fracture tight.Then, utilization will be in the alignment direction of magnetic field and the crystallization plane of fracture is tight is engaged and unanimously does compression molding, and becomes the highdensity permanet magnet of the entanglement without orientation, and can obtain high-performance magnetism stone.
U.S. Patent Publication No. US20100034688 is disclosed in when alloy raw material powder is carried out to magnetic field orientation, because apply magnetic field on one side, stir alloy raw material powder simultaneously in filled chamber, so mutual position relationship of particle of the alloy raw material powder in filled chamber, be that state from being filled in filled chamber changes, there is the chance that the crystallization plane of fracture of the alloy raw material powder of more equal crystal orientation relation is combined and become many.
But the alignment direction of the permanet magnet that patent US20100310408 discloses with patent US20100034688 is vertical each other with compression aspect, therefore will be limited in shape of magnetite.The orientation of the permanet magnet in aforementioned and pressue device all must utilize the magnetic pressue device (complex mechanical structure of for example Hydraulically Operated Equipment) of complicated frame for movement to carry out the step of magnetic pressurization in addition.Moreover orientation and the pressue device of the permanet magnet in aforementioned all must provide respectively the energy to coil and magnetic pressue device, cannot carry out with the single energy step of magnetic orientation and magnetic pressurization.
Orientation and the pressue device of the permanet magnet in TaiWan, China patent publication No. TW201201226.Pair of magnetic field generating coil is disposed to the upper-lower position of die cavity, the magnetite powder that is filled to die cavity is applied to the magnetic line of force.The magnetic field that need are applied is made as for example 1MA/m.Then,, in the time carrying out press-powder shaping, first dry magnetite powder is filled to die cavity., drive low punch and upper punch, the magnetite powder that is filled to die cavity is exerted pressure and made its shaping along the direction of arrow thereafter.In the time of pressurization, to being filled to the magnetite powder of die cavity, utilize magnetic field generating coil to apply pulsed magnetic field along the direction of arrow parallel with compression aspect again.The magnetic line of force that this design produces is easily a parabola, and on each position of magnetite apart from the difference of coil, cause the inequality of magnetic force on same plane.
The orientation of the permanet magnet in aforementioned and pressue device all must utilize the magnetic pressue device (complex mechanical structure of for example Hydraulically Operated Equipment) of complicated frame for movement to carry out the step of magnetic pressurization in addition.Moreover orientation and the pressue device of the permanet magnet in aforementioned all must provide respectively the energy to coil and magnetic pressue device, cannot carry out with the single energy step of magnetic orientation and magnetic pressurization.
Therefore, just have a kind of method of manufacturing the device of magnetite and manufacturing magnetite need to be provided, to solve aforesaid problem.
