ABSTRACT:
A wiredrawing diestock having wire inlet and outlet openings aligned coaxially with the a die aperture there-between. The diestock has a first chamber disposed around the wire inlet. It has a second chamber surounding the die. Several openings provide communication between the two chambers and allow the flow of liquids from the first to the second chamber. These latter openings have positions equally spaced from the axis of a wire being drawn through the wire inlet opening and the die. The openings have individual axes which converge at the axis of the wire at a point where the wire enters the die. The lubricating cooling liquid, fed under pressure to the first chamber, flows through these openings in streams having flow paths converging on the wire being drawn. The pressure of the liquid is maintained in the second chamber. Liquid can escape from that chamber only through the wire inlet and outlet openings, and these openings are largely filled by the wire passing through them. Preferably the diestock comprises a body which has two pivoted halves, capable of being opened and closed and housing the die therein.
