Description
Technical field
The utility model relates to machining manufacturing technology field, is a kind of portable demagnetizer simple, easy operating that is easy to carry, regulates.
Background technology
At present existing industrial demagnetizer can be divided into two kinds, and a kind of is after adding AC power by degaussion coil, to produce alternating magnetic field in degaussion coil, and when workpiece is at the uniform velocity passed by from alternating magnetic field, magnetic field intensity is demagnetized because of linear attenuation.Another kind is the magnetic field that produces a concussion decay by discharging and recharging between the inductance capacitance, makes to act on to be changed by the magnetic direction of demagnetization workpiece and strength decrease reaches the purpose of demagnetization.
Handle though these two kinds of demagnetizers can carry out the demagnetization of a plurality of workpiece simultaneously, because it need use the pulse phase shift technology, and adopts the nonpolarity big electric capacity of oil-immersed and high-voltage, less stable does not have autgmentability, keeps in repair more loaded down with trivial details yet.
The utility model content

Demagnetization principle of the present utility model is:
When feeding the 220V power-frequency voltage, demagnetizer utilize the characteristic of thermistor (PTC) in circuit, to produce the alternating current of a concussion decay, thereby produce the progressively magnetic field of decay, utilize logical circuit intelligent controller control DC motor positive and negative rotation, judge whether the demagnetization workpiece is placed to station A, be the position on motor side top with photoelectric sensor, the magnetic flux of the workpiece before can measuring the Ci that do not disappear with gaussmeter on this position.Stepping motor running back workpiece is transferred band and is transported to station B, is the lower end of iron core, when transducer is measured to workpiece arrival iron core below, the demagnetization circuit is connected, the alternating voltage of decay makes the decay magnetic field that produces alternation in the degaussion coil, this magnetic field all changes the direction and the intensity in the magnetic field of workpiece, magnetic field intensity is successively decreased, thereby reaches the purpose of demagnetization.In order to reduce remanent magnetism, when the erasing current effect behind the certain hour, the stepping motor entry into service is taken workpiece the lower end of iron core out of with speed slowly, to the motor drive direction motion, forms the distance increase in workpiece and magnetic field, this also is the process of further demagnetization; Cancellation remanent magnetism comparatively completely.
Degaussing process of the present utility model is:
Insert the 220V power-frequency voltage earlier, the workpiece that needs demagnetization is placed on the conveyer belt, the erasing time of different demagnetization materials is determined by the logical circuit intelligent controller: if the demagnetization workpiece is a hard magnetic material, the time of connecting the anti-magnetized coil electric current so can be longer; If the demagnetization workpiece is a soft magnetic material, the time can lack so.Press starting switch, represent operating state by indicator light.After the demagnetization, be that the workpiece of motor upper end carries out magnetic detection with gaussmeter, confirm whether the demagnetization workpiece has finished demagnetization resting on station A place.
The good effect of a kind of portable demagnetizer of the utility model is:
(1) adopt logical circuit intelligent controller (LOGO) to carry out the control of demagnetization, and utilize the magnetic flux of the measurement function on-line monitoring workpiece of gaussmeter, solve different ferromagnetic materials magnetic permeability, rectify problems such as stupid rate, magnetic hysteresis loop be variant, can carry out demagnetization to different irony magnetic materials, improved the demagnetizer reliability of products, can adapt to than the wide industrial environment;
(2) can eliminate the magnetic field that metal parts produces in the course of processing, be particularly useful for the demagnetization of micro metal part, anchor clamps, little mould, small workpiece, gadget, and can carry out demagnetization to a plurality of workpiece simultaneously and handle, demagnetization efficiency obviously improves, and the demagnetization cost obviously reduces;
(3) on demagnetizer, be connected with magnetic detection device, can the workpiece after the demagnetization be detected immediately;
(4) equipment volume is small and exquisite, makes, uses and carry all very convenient.
