Description

The invention relates to mechanical engineering and can be used, for example, in continuous surface grinding machines for demagnetizing parts converging from the table.

The purpose of the invention is to reduce energy consumption during demagnetization of products of various shapes.

FIG. 1 shows a device for demagnetization (a mechanism for symmetrically varying the angle between the coils is not shown); in fig. 2 is a diagram of a device with an angle adjustment mechanism between coils.

The degaussing device comprises a tray 1 passing through the windows of the inner coil 2 and the outer coil 3.

Coils 2 and 3 are offset one relative to the other by an angle a and are connected to voltages that are out of phase by an angle p. To adjust the angle a (rotation of the coils around the axis A), a rotation mechanism is used, which is made as follows: levers 4 are attached to coils 2 and 3. The latter are attached to bars 5, which are threaded (on one right ). The nut 6 is screwed on the bolt 5 with the thread.

To adjust the phase angle, tap coils are used, allowing them to be connected either to direct or phase voltages of a three-phase network.

The device for demagnetization works as follows.

Parts pass through tray 1 through a demagnetizer under their own weight or force. The choice of the angle a and p provide such a sum so that the shape of the demagnetizing field most closely matches the shape of the demagnetized product. So, if this sum is 180 °, then the field is

circular and it is intended for demagnetization of parts such as rings. The indicated amount is less than 180 °, the more elongated along the axis of the tray the shape is.

the demagnetizing field thaws, and in it the efficiency of the 5th tray is rollers, pieces of pipes and the like, effectively demagnetizing sliding parts, along the tray the slats, rollers and the like.

The more the angles are and the greater the 180, the more elongated across the tray the shape becomes the field of the demagnetizer and it is more efficiently demagnetized rolling along
