The effective repair and maintenance of the wire drawing mold can appropriately reduce the cost, and severe wear and tear will cause the mold to have transverse cracks (mainly appear in the drawing process of soft wire) or longitudinal cracks (mainly appear in the drawing of hard wire), resulting The mold was scrapped prematurely. Therefore, according to the types of wire rods to be drawn and the characteristics of wire drawing, the maintenance specifications for wire drawing dies should be scientifically formulated. Under normal circumstances, slight annular wear only needs to be polished to resume use, or a slightly enlarged diameter can meet the drawing requirements. Excessive wear will greatly reduce the number of mold repairs.
