Abstract
A demagnetizer with ring magnetic field is composed of machine frame and a special magnetic circuit consisting of upper and lower two groups of magnetic poles, each of which is composed of two magnetic poles in different directions to form a longitudinal magnetic field and a transverse magnetic field.
Description
The utility model relates to a kind of improved demagnetizer, belongs to the demagnetizer field.
At present, the demagnetizer of widespread usage in the research and production field is that the inductance coil with a ribbon core passes to alternating current, produces an alternating magnetic field, when the workpiece of needs demagnetization is put into and shifted out thereupon, can carry out demagnetization.Demagnetizer is generally established a pair of magnetic pole, the upper and lower surface of the workpiece that is placed in.This demagnetizer still can be competent at the demagnetization of general workpiece, but concerning the comparatively complicated workpiece of some structures and shape, demagnetization effectiveness is not satisfactory, and this is because complicated structure needs the magnetic field of corresponding different directions to adapt to, and just can reach best demagnetization effectiveness.Therefore, only adopt a pair of magnetic pole to oversimplify processing, can not finish this task.
The purpose of this utility model provides a kind of design of improved demagnetizer, and it can effectively demagnetize to the structure and the comparatively complicated workpiece of shape of abnormal shape.
The purpose of this utility model is achieved in that the magnetic circuit of redesign demagnetizer, makes its existing longitudinal magnetic field, and a transverse magnetic field is arranged again, to adapt to the needs of workpiece different piece demagnetization respectively.
A basic toroidal magnetic field demagnetizer is made up of frame and the magnetic circuit that is used for workpiece demagnetization, two groups of magnetic poles about its magnetic circuit is divided into, and every group of magnetic pole is made up of magnetic pole 1-1,1-2 and magnetic pole 2-1,2-2 respectively again.Magnet ring band 3 is the annular of a sealing.Each magnetic pole all is fixed on the inboard of magnet ring band 3, and the magnetic direction of each magnetic pole and the magnetic direction of adjacent pole are all inequality.
In order further to improve demagnetization effectiveness, the iron core in the utility model also can be designed to be made up of 2～5 little iron cores, and the dividing plate made from nonferromagnetic material between each little iron core 4 separates.
When demagnetizer is handled the workpiece of different sizes, in order to improve demagnetization effectiveness, magnet ring band 3 in the utility model is connected with a distance adjustor, described distance adjustor is made up of leading screw 9, thick stick mother 8, transverse slat 6 and adjustment disk 11, establish one between transverse slat 6 and the magnet ring band 3 and be connected 7, it is fixed together magnet ring band 3 and transverse slat 6, and the thick stick on the transverse slat 6 is female to be meshed with leading screw, can drive transverse slat 6 and move up and down.Two ends at transverse slat 6 are porose, are placed in respectively on the feed rod 13, and its effect is to make transverse slat 6 directed slips.The upper end secured adjusted dish 11 of leading screw 9.
Press the demagnetizer of said structure design, 1-1 in the magnetic pole and 2-1; 1-1 and 2-2 will constitute a longitudinal magnetic field respectively; 1-1 and 1-2; 2-1 and 2-2 will constitute a transverse magnetic field respectively.When demagnetizing operation, the magnetic field of both direction in workpiece, is improved its demagnetization effectiveness with acting in conjunction greatly.
Below with reference to accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A profile that has amplified.
Frame in the utility model is assembled by transverse slat 12,14 and feed rod 13, and feed rod also provides guide effect for moving up and down of transverse slat 6 except that working the binding effect of going up lower cross plate.The magnetic circuit bottom of demagnetizer is fixed on the transverse slat 14, and top is fixed on the transverse slat 6.When rotating adjustment disk, leading screw drives link 7 motions, and the distance between the upper and lower of magnet ring band 3 is adjusted.Like this, big spacing can be put bigger workpiece into, and little spacing can be put into less workpiece, thereby makes the magnetic field intensity that acts on workpiece big as far as possible, to improve demagnetization effectiveness.
Iron core in the utility model is made up of some little iron cores, during operate as normal, the magnetic line of force will concentrate on the iron core part more, and near the magnetic field intensity the iron core is greater than the magnetic field intensity at dividing plate place, thereby making up and down the magnetic field between two groups of magnetic poles is not a uniform magnetic field, but the magnetic field of a variation.She Ji purpose like this is when workpiece 15 is moved with workbench 10, and its magnetic field intensity will experience decay several times, and the magnetic field of this variation will help the raising of demagnetization effectiveness.
Iron core in the utility model adopts the ordinary silicon steel disc, and the sheet metal choosing dress that magnet ring band 3 can utilize soft magnetic material to make forms, and certainly, also can manage to adopt common belt silicon steel sheet.The parameter of solenoid can be by the coil design of common demagnetizer, and winding wiring should be able to guarantee that the magnetic direction of each magnetic pole is different with the magnetic direction of adjacent pole, and dividing plate 4 can adopt plastic plate or laminated sheet
