ABSTRACT:
Lubricating die holder comprising a supportable body containing a die holder chamber having an entrance opening and an exit opening respectively extending therefrom to the front entrance side and rear exit side of the body and defining a die drawing path extending through the body from the entrance opening into the chamber and in turn from the chamber to the exit opening, the chamber being adapted to receive operatively movably therewithin a separate drawing die of the type capable of reducing the size of a wire passing along the path from the entrance side to the exit side of the body, and a lubricating coolant flow conduit system terminating in a feed aperture arrangement flow communicating with the chamber and entrance and exit openings and arranged for feeding lubricating coolant into direct contact with the die and wire in the chamber and in the entrance and exit openings, e.g. in a direction crosswise of the path, preferably with the chamber having a slide surface facing the entrance opening and crosswise of the path for sliding contact with the adjacent portion of the die to permit its self-centering relative to the path within the adjacent confines of the chamber, so that the die may be received operatively movably in the chamber in floating self-centering disposition therewithin relative to the path and arranged for direct contact of lubricating coolant therewith in any position of floating self-centering movement of the die relative to the feed aperture arrangement.
