Accurate control of product outer diameter deviation : due to the uninterrupted production of copper wire drawing equipment, the drawing speed will gradually be out of sync with annealing, which will cause the wire diameter to appear due to the fast and slow traction speed during drawing Intermittent and irregular changes . Carry out good lubrication to the wire storage to prevent it from causing reverse friction to the wire during high-speed operation and thus make the wire thin ; adjust the tension of the wire so that the wire drawing stroke is always close to the annealing wheel ; to ensure the annealing wheel The steel ring is in good condition to avoid unstable annealing current due to surface defects of the steel ring . Re-match the wire drawing machine according to the actual situation of the wire drawing machine: adjust the diameter of the adjustable V-belt pulley on the annealing wheel drive shaft according to the wire drawing principle , so that the annealing wheel speed / fixed speed wheel speed = forward slip coefficient × fixed speed Wheel diameter / annealing wheel diameter, where the diameters of the fixed speed wheel and annealing wheel are known, the speed of the fixed speed wheel and annealing wheel can also be measured , and the forward slip coefficient can be obtained from the slip coefficient. The machine re-matches the molds so that the matched molds can meet the requirements.
