The invention relates to surface treatment and can be used to clean the surface and create microrelief products on the surface.

The purpose of the invention is the expansion of operational capabilities.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 and 4 - the surface of the product after processing the device.

The device for surface treatment of products includes a cylindrical brush consisting of a shaft 1 (Fig. 1 and 2), a pile 2 of ferromagnetic material, two electromagnets 3 and 4 placed oppositely (Fig. 2) along the periphery 5 of a pile 2 from the ends 6 and 7 cylindrical brushes. The device is equipped with a power supply unit 8 for electromagnets 3 and 4 and a current control unit 9 for electromagnets 3 and 4. The brush is driven into rotation by an electric motor 10 connected to the shaft 1 of the coupling 11. The workpiece (steel tape) is indicated with the position 12. The surface microrelief of the tape 12 after processing is indicated position 13 (Fig. 3) and position 14 (Fig. 4).

The device works as follows.

The cylindrical brush rotates from the electric motor 10 and the periphery 5 of the pile 2 of ferromagnetic material and treats the surface of the steel tape 12. During the processing using the power supply nodes 8 and 9, the electromagnet current control alternately switches the opposed electromagnets 3 and 4. It is ferromagnetic pile under the action variable magnetic field in the process of movement on the treated tape is deflected either towards the electromagnet 3 or towards the electromagnet 4. It depends on the frequency from eneni and magnetic fields that are provided by nodes and power control currents of the electromagnets is obtained varying the trajectory of movement of the villi in the area of surface treatment. The surface microrelief is obtained in the form of parallel wavy lines (Fig. 3) or intersecting lines (Fig. 4). Figure microrelief on top

Depending on the requirements for it, determined by the further use of the products, they are easily controlled by the magnitude and frequency of the current pulses supplied by the nodes

power supply and current control of electromagnets, the speed of rotation of the brush and the speed of movement of the product.

An adjustable electric pulse generator known in the art is used as power supply and current control nodes for electromagnets.

The surface of the product in many cases determines their performance characteristics. So, in order to improve the gripping of the lubricant during the subsequent processing of products (by drawing, shtampovka, etc.), it is necessary to have an isotropic surface, the microrelief of which well holds the lubricant. When gumming products, for example when using them as bead wire and tape for automotive clothing to improve the adhesion of rubber to metal, it is also necessary to have an isotropic surface developed.

The proposed device allows changing the currents of electromagnets to get

Any given surface microrelief is the most optimal from the point of view of further use of products. In addition, the device provides a decorative surface with a repeating pattern. The device has a simple and reliable design, there are no mutually moving parts. This reduces its cost and increases reliability.
