Description

The invention relates to electrical engineering, namely, devices for demagnetization of parts made of magnetic materials.

A device for demagnetization, parts, comprising a demagnetization coil, a capacitor bank, a power source and a switch l)

A disadvantage of the known device is the complexity of the design.

The closest to the present invention is a device for demagnetization of parts containing a base, magnetic cores, permanent magnets in the form of rectangular parallelepipeds, the opposite planes of which serve: - poles, an electric motor with a shaft for moving permanent Magnets t2; l.

The disadvantages of this device are the low demagnetization quality and small range of application.

The purpose of the invention is to improve the quality of degaussing.

The goal is achieved by the fact that a device for demagnetization of products containing a base, magnetic cores, permanent magnesium in the form of rectangular parallels and pedals, opposite planes of which serve as poles, an electric motor with a shaft, add} 1 bnly equipped with two constant magnet and mH as two Others of the magnet are located radially on the two magnetic cores, fixed coaxially on the motor shaft so that the opposite magnets have opposite polarity, and one of the first solenoids Inonii motor shaft and keyed into an axial movement possibility.

FIG. 1 shows the device; in fig. 2 is a sectional view in FIG. one

The device for demagnetization of products consists of a base 1, magneto conduits 2 and 3 of magnetically soft material, on which permanent magnets 4-7 are attached radially

(for example, samarium-cobalt marks KS 37A GOST 21559-76) in the form of rectangular parallelepipeds, the opposite planes of which serve as poles, housings 6-10, slider 11, on which the shaft 12 of the magnetic core 2 is fixed, the keys 13, which fit symmetrically permanent magnets on magnetic cores 2 and 3 and a torque from vaAa of electric motor 14, screw 15, handwheel 16, guide 17, holder 18 and demagnetized part 19l

The magnetic module 2, fixed on shaft 12, has the possibility of axial movement, which allows adjusting the gap between the magnetic conductors (2 and 3. The shaft of the electric motor 14 is connected to shaft 12 of magnetic circuit 2 by key 13.

The device is given the demagnetization of products works as follows.

At the beginning of the rotation of the screw 15 by the handwheel 16, a gap is set across the width of the demagnetized part 19 between the housings 8 and 1Q of the magnetic cores 2 and 3.

When electric motor 14 is turned on, magnetic flues 2 and 3 with permanent magnets 4-7 begin to rotate synchronously, creating; strong alternating magnetic field. The holder 18 with the demagnetizable part 19 is inserted into the direction of the junction 17 and is inserted into the gap between the shells 8 and 10,.;. .,., -. ; . ; .. .- ..

The demagnetization of parts is carried out by holding them in an alternating magnetic field with their subsequent removal from the field.

A device for demagnetization of products allows improving the quality of demagnetization of parts by increasing the voltage of the alternating magnetic field and allows. demagnetize parts of various sizes due to the possibility of adjusting the gap between the magnetic cores.
