Description
Technical field
The utility model relates to a kind of magnetic material process equipment, is specially a kind of magnet charger.
Background technology
Magnetic material is widely used in a lot of fields such as sound appliances, motor, instrument, magnetic machinery processing.Magnetic material is before carrying out the magnetic detection or before being assembled into the device that possesses certain function, need magnetize in magnet charger just can have magnetic.Magnetic material magnetizes and need carry out under high-intensity magnetic field, and for example the Nd-Fe-B permanent magnetic material generally is more than the 2T (tesla) to the magnetic field requirement of magnet charger, the Nd-Fe-B that coercive force SH shelves are above
Permanent magnetic material requires magnet charger to provide the above magnetic field ability of 3T (tesla) saturated.Existing magnet charger is divided into three kinds by the power supply presentation mode that magnetizes: pulsed magnet charger, capacitive magnetizing apparatus and electromagnet type magnet charger.Existing pulsed magnet charger is powered with two-phase power supply, and its voltage is low, energy is little, can only produce enough magnetic field in the solenoid of very little at internal diameter (Φ is below 30), and the scope of application is very narrow; The pulse high current that existing capacitive magnetizing apparatus utilizes capacitor discharge to produce produces magnetic field by solenoid magnetic material is magnetized, can in the solenoid of any specification, produce enough magnetic field theoretically, but its charging capacitor price is very high, complete machine cost height, the electric capacity charging needs the long period again, the solenoid cooling is bad, and easily heating is so continuous operation for a long time; The electromagnet type magnet charger can be accomplished very big, magnetic field does not need to charge and directly sets up, it is overheated that the solenoid cooling better is difficult for, but because its solenoid is to be fixed on the iron core, the workpiece that is magnetized during work is positioned at the solenoid outside, its magnetic field can only reach 2-2.4T, and cost is also high, and practical application effect is not good.
Summary of the invention
The utility model solves problem and the defective that existing magnet charger exists, be that its supply voltage of pulsed magnet charger is low, energy is little, it is very high to produce enough magnetic field, capacitive magnetizing apparatus charging capacitor price in can only the solenoid of very little at internal diameter (Φ is below 30), complete machine cost height, the problem that electromagnet type magnet charger magnetic field intensity is low provide a kind of magnet charger.
The utility model is to adopt following technical scheme to realize: magnet charger, and comprise frame, be positioned at the solenoid of central rack and be positioned at the solenoid elevating mechanism of frame lower, also comprise three-phase high-voltage pulse power cabinet to the solenoid power supply; Simultaneously, be provided with at the top of frame and middle part and be positioned on the solenoid center line and polarizable magnetic pole that the position is relative.This magnet charger has adopted three-phase high-voltage pulse power cabinet to power to solenoid, and its voltage height, energy are big, therefore, can increase the internal diameter (can increase to Φ 200) of solenoid; Simultaneously, the frame that permeability magnetic material is made has formed the magnetic circuit of solenoid, can reduce the magnetic resistance loss of magnetic circuit, help improving magnetic field intensity, particularly polarizable magnetic pole (is used polarizable material, make as pure iron etc.) setting, not only further reduced the magnetic resistance of magnetic circuit, and polarizable magnetic pole is magnetized under the action of a magnetic field that solenoid produces, generation and solenoid be the earth magnetic field in the same way, the magnetic field intensity of the inner chamber of the solenoid after internal diameter increases is fully improved, make the magnetic field of solenoid inner chamber generation greater than 3T.
During work, part to be magnetized is placed between the polarizable magnetic pole, the elevating mechanism of frame lower is with solenoid jack-up, make polarizable magnetic pole and between the part that magnetizes waited enter the inner chamber of solenoid fully, three-phase high-voltage pulse power cabinet is powered to solenoid, and the solenoid inner chamber produces the highfield, polarizable magnetic pole is magnetized fast and produces the magnetic field identical with the magnetic direction of solenoid, two magnetic field superposition produce highfield (magnetic field intensity is greater than 3T), and part to be magnetized is magnetized; Then, elevating mechanism descends coil, takes out and is magnetized part.
From the above-mentioned course of work as can be seen, the effect of the elevating mechanism of solenoid is placement and the taking-up for the ease of being magnetized part.The structural design of the elevating mechanism of solenoid is for the technical staff of mechanical field, need not performing creative labour just can easily finish, can adopt multiple known structural design, as the mechanical elevating mechanism of various motors or hand drive, hydraulicefficiency elevation structure etc.
In the described three-phase high-voltage pulse power cabinet pulse-generating circuit is arranged.Three phase mains produces high hard pulse by known pulse-generating circuit.Described pulse-generating circuit is that the technical staff of electricity field is very easy to realize.Therefore, three-phase high-voltage pulse power cabinet is existing known products.
Magnet charger described in the utility model has adopted the three-phase high-voltage pulse power to provide enough energy for solenoid, and form magnetic circuit by permeability magnetic material in the solenoid periphery, reduce the magnetic resistance loss, add the setting of polarizable magnetic pole, make this magnet charger realize producing magnetic field greater than 3T at the solenoid inner chamber of internal diameter Φ 200.The increase of solenoid internal diameter can realize that the highfield has guaranteed fully magnetizing to workpiece to the magnetizing of big workpiece.Magnet charger structural design novelty described in the utility model, reasonable, cost performance is higher, and is better compatible, overcome the defective and the deficiency of existing magnet charger, is a kind of desirable upgrading products of magnet charger.
