Maintenance and repair of wire drawing mould

The effective maintenance and repair of the drawing die is very important to reduce the drawing cost.

Due to the vibration of the wire, the area of the wire that first came into contact in the compression zone of the drawing die first produced a slight ring-shaped wear, and then continued to expand to the sizing area, which caused the performance quality of the wire to seriously decrease and the wire size to expand. Not only that, severe wear will cause the mold to produce transverse cracks (mainly in the drawing of soft wires) or longitudinal cracks mainly in the drawing of hard wires, resulting in premature scrap of the mold.

Brushed maintenance

Therefore, according to the type of wire drawing material and the characteristics of the wire drawing machine, scientifically formulate the wire drawing die maintenance specifications. Under normal circumstances, slight ring wear needs to be polished to resume use, or a slightly enlarged diameter can also meet the drawing requirements. Excessive wear will greatly reduce the number of mold repairs and even scrap, which will increase the cost of wire drawing.
