Application requirements of wire drawing machine

- Feb 17, 2020-

(1) The installation foundation of wire drawing machine shall be fixed firmly to avoid vibration;           

(2) During installation, the tensile axis of the wire rod shall be symmetrical with the center line of the die hole through debugging, so as to make the stress of the wire rod and the wire drawing die even;           

(3) In the process of drawing, it is necessary to avoid frequent starting and stopping, because the friction caused by the tensile stress at the beginning of drawing is much greater than that caused by normal drawing, which will increase the wear of die.           

In addition, the wire used for drawing should be pretreated: surface pretreatment and heat treatment.            (1) Surface pretreatment: for the wires with dirty surface and more impurities, they should be cleaned and dried before drawing; for the wires with more oxide skin on the surface, they should be acid fine and dried before drawing; for the wires with peeling, pit, heavy skin and other phenomena on the surface, they should be polished by a grinder before drawing;           

(2) Heat treatment: for the wire rod with excessive hardness or uneven hardness, the hardness shall be reduced by annealing or tempering, and the wire rod shall be kept with good hardness uniformity before drawing.
