WIRE DRAWING

摘要

An apparatus for wire drawing including a die and a rotatble block around which the wire leaving the die is arranged to be wrapped, a cooling means located between the die and the block for cooling the wire using a coolant and a wiping means for wiping substantially all the liquid coolant from the wire before it passes onto the block. The cooling means is in the form of an elongated chamber through which the wire is arranged to pass whilst in a substantially straight configuration and moving in the direction of its length. The chamber is provided with nozzles arranged to direct jets of the liquid coolant onto the straight moving wire and with a slot which extends longitudinally from one end of the chamber to the other. A deformable baffle which forms part of the wall of the chamber extending across this slot and allows a substantially straight length of wire to be inserted into and withdrawn from the chamber through the slot by movement of the straight length relative to the chamber in a direction substantially at right angles to the longitudinal axis of the straight length thus deflecting the baffle.
