The purpose of this utility model is achieved by the following technical solution:
A kind of portable Magnetizing and demagnetizing machine, comprise shell, fill demagnetization line bag, fill the control circuit in demagnetization switch and shell, the magnet-wire bag that magnetizes is fixedly mounted with in the enclosure, and the magnet-wire bag that magnetizes is coaxially arranged with the workpiece that magnetizes and places mouthful, and what control circuit was installed on shell fills demagnetization switch.
And; the structure of described control circuit is: fill demagnetization line bag by normally opened relay J, fill demagnetization K switch and connect the Darlington transistor being formed by two diode group 3DGIT and 3DD1 and carry out voltage stabilizing, oscillator coil L exchanges cut-off circuit with diode 2CP12 composition and protects Darlington transistor.
Advantage of the present utility model and good effect are:
1, this Magnetizing and demagnetizing machine adopts AC power, form current-limiting circuit by diode and resistance, individual event SCR control break-make, fill the time of demagnetization by the normally opened contact control of relay, two diode group 3DGIT become Darlington transistor to carry out voltage stabilizing with 3DD1, improved current amplification factor and power output, coil J exchanges cut-off circuit protection Darlington transistor with diode 2CP12 composition; While magnetizing, bidirectional triode thyristor conducting, by discharging and recharging of capacitor C 1, coil L1 produces alternating magnetic field, and the element being opposite in magnetic field magnetizes.This Magnetizing and demagnetizing machine adopts 220V50Hz mains-supplied, and plant capacity only has 2000W, has greatly reduced power consumption, save special supply line, dwindled the volume of Magnetizing and demagnetizing machine, alleviated weight, real realization portable, for convenience of transport provide may.
2, this Magnetizing and demagnetizing machine utilizes the enamelled wire coiling of 2mm diameter to fill demagnetization line bag, has reduced power consumption, has saved manufacturing cost, easy to process and relatively cheap; Control circuit board is also to adopt conventional electronic devices and components to weld, for later maintenance is provided convenience.
3, this Magnetizing and demagnetizing machine has been installed aluminum metal shell, and outward appearance is beautiful, solid, durable.
