FIELD: metallurgy. ^ SUBSTANCE: soap dish is comprised of a body consisting of several sections, condensing elements and the drawing mechanism. Increase in the firmness of draw rings, owning to equalization of resistance to friction and reduction of resistance to drawing, can be provided with the soap dish that contains vibration mechanism equipped with either one or a few vibrators of lateral ultrasound vibrations. These are set outside the soap dish's frame in the horizontal and vertical axes which traverse across the drawing axis. This creates an opportunity of alternating the direction of vibrations and turning the lateral vibrations of concentrates in the curved vibrators of waveguides that are delivered at the drawing instrument. The waveguides are linked with the concentrates of vibrators and set in such a manner that it may be possible to extract them from the soap dish itself, to shift them both vertically and horizontally within the support frames assembled at the vibration junctions. Herewith the drawing instrument is supplied with clamps that enter through the grand box in the tight tapped, conical or wedge-type connexion with the waveguides that are, in turn, tightly connected through the grand boxes with the concentrates of vibrators. ^ EFFECT: vibration mechanism's location outside the soap dish permits to use the vibrating movements without having to change or complicate its construction. ^ 7 dwg3311998 |
