Effective protection and repair of wire drawing dies are crucial for reducing costs. Due to the oscillation of the wire, the first touch area of the wire in the compression zone of the drawing die undergoes slight circular wear, and then continues to expand until the sizing area, resulting in severe deterioration of the surface quality of the wire and expansion of the wire scale.
Not only that, severe wear and tear can also lead to transverse cracks (mainly during the drawing process of soft metal wires) or longitudinal cracks (mainly during the drawing process of hard metal wires) in the mold, which can result in premature invalidation of the mold. Therefore, it is necessary to scientifically formulate protection standards for wire drawing molds based on the type and characteristics of wire drawing. Generally speaking, minor circular wear can only be restored after polishing, and perhaps a slightly larger diameter can meet the requirements of wire drawing.
Excessive wear will greatly reduce the number of mold repairs and even render them useless, resulting in an increase in wire drawing costs.
