Description
Technical field
The present invention relates to the manufacture field of permanent magnetism ring, the preparation facilities of especially a kind of permanent-magnetic ring of radial orientation.
Background technology
The first is that the employing magnetic pole principle of same-sex repulsion mentioned in 200510086882.9 produces radially oriented magnetic field for application number. Radiation field is produced by same pole electro-magnet by one, the direct current of each electro-magnet or pulsed current produce N pole or S pole, due to the magnetic line of force that the identical generation of polarity of two electro-magnet repels each other, two are moved to die cavity direction with pole magnetic head by pressing process simultaneously, makes it form a radiation field by leading magnetic mould. The method makes annular magnetic obtain guarantee to a certain extent in the homogeneity of circumferential direction, but the homogeneity of annulus in height direction is very poor, and weak point maximum in addition is that the alignment magnetic field obtained when the internal diameter of radial ring is less can reduce greatly. Automatic Magnetic field press prepared by employing present method is such as the patent No. 02203908.2 and the patent No. 01219246.5.
2nd kind is segmentation orientation manufacture permanent magnetism ring such as application number is 200710106670.1: by annulus along the circumferential direction segmentation orientation, import magnetic field respectively to each section and carry out orientation, though the method achieves radial orientation, but along the circumferential direction orientation degree is uneven to cause annulus. The uneven overall magnetic performance that not only can seriously affect radial ring of orientation degree, and the shrinking percentage of different orientation degree position in sintering process can be caused different and cause stress to be concentrated, more serious makes radial ring opening.
The third mentions the alignment magnetic field utilizing and being produced by the alternating-current of electro-magnet to rotate for application number 200910201694.4, thus realize rotatingfield and annular magnetic is carried out orientation, can realize most strength, magnetic field successively rotation sweep cross every part of magnet, decrease kinematic pair, but magnet orientation along the circumferential direction exists ununiformity.
Summary of the invention
The technical problem to be solved in the present invention is: the preparation facilities providing a kind of permanent magnetism ring that can obtain good orientation in radial magnetic field.
The technical solution adopted for the present invention to solve the technical problems is: the preparation facilities of a kind of permanent-magnetic ring of radial orientation, comprise the upper of press, bottom end rail, produce the line bag in magnetic field, press column, upper cylinder, lower oil cylinder, frame, as the annular magnetic conductive board of outer magnetic pole, lead the outer magnetic pole connection bracket of magnetic, auxiliary oil cylinder and play the portable plate of support structure or/and retaining plate, die cavity outer wall, as lead in the die cavity of internal magnetic pole magnetic plug and non-magnetic on, lower punch, described outer magnetic pole connection bracket fixes outer magnetic pole, the thickness of outer magnetic pole is much smaller than the height of die cavity, when line bag is connected with magnetizing current, radial magnetic field is produced in the scope space of the die cavity between plug and outer magnetic pole, powder in die cavity back and forth moves up and down under the promotion of oil cylinder, powder is circulated successively the plane by outer magnetic pole place while compacting.
The line bag in generation magnetic field of the present invention is separately positioned on the upper and lower of press; The upper and lower of press arranges envelope curve and/or lower envelope curve respectively. Described die cavity outer wall is annular, is fixed on portable plate or retaining plate; Die cavity outer wall can be the integral construction of single annular, it is possible to be spliced by the tile of multiple arc. The motion of annular die cavity outer wall is that the cylinder movement connected by portable plate or retaining plate is realized.
The motion of upper and lower punch of the present invention is realized by cylinder movement, the motion of upper male mould is moved by upper cylinder and is realized, lower punch is fixed on portable plate or retaining plate, and the motion of the lower punch being fixed on portable plate is realized by the motion of auxiliary oil cylinder. Motion as internal magnetic pole plug is controlled by lower oil cylinder or auxiliary oil cylinder, and ejects after adding powder, and compacting moves downward after terminating and sloughs plug.
Top end rail of the present invention is connected between pillar with press column and outer magnetic pole to belong to be slidably connected, and driving during orientation to belong between the portable plate driving lower punch motion during portable plate or the orientation of die cavity motion and be rigidly connected, its motion is realized by the motion of auxiliary oil cylinder or lower oil cylinder.
The invention has the beneficial effects as follows: owing to outer magnetic pole thickness is much smaller than powder height in die cavity so that formed between outer magnetic pole with internal magnetic pole and compare the radial magnetic field concentrated, intensity is higher. When the powder in die cavity is through outer magnetic pole place plane, above-mentioned radial magnetic field can obtain good orientation. Along with all powders order and when iterating through the plane at outer magnetic pole place and obtain compacting, powder in whole mould can obtain fully, uniform orientation, greatly improve the radial orientation homogeneity of radial permanent magnetic ring, also improve orientation degree homogeneity in the axial direction simultaneously, particularly for highly higher radial ring, its advantage is more obvious; The preparation facilities of the present invention can adopt hand-stripping and automatic demoulding two kinds of modes in addition, and operation is more flexible, greatly improves the qualification rate suppressing radial ring.
