Device for mechanical cleaning of wire rods for the production of drawn metallic wires

Device for mechanical cleaning of wire rods for production of drawn metallic wires, comprising a pair of elements supported by a shaft, each element comprising a truncated-conical body and a flat disk that covers the truncated-conical body, defining an internal annular space that contains steel wool;

• the flat disk being provided with openings shaped like a slot;
• the two elements being disposed one in front of the other along a plane of symmetry, wherein a space is provided between the two flat disks, said space being suitable for receiving said wire rod;
• wherein, during the operation, by means of a rapid rotation of the shaft, said steel wool expands under the effect of a centrifugal force in radial direction, thus creating an axial thrust component on said steel wool towards said flat disks in such a way that said steel wool escapes partially and elastically from the openings of the flat disks, so that the steel wool brushes against the surface of the wire rod that is in transit in the space between the two elements, thus producing a cleaning action on the surface of the wire rod in contact with the steel wool by means of high-speed rubbing.
