1, check the stamping die manufacturing materials are appropriate, the corresponding heat buried process is reasonable. Through the stamping die heat treatment process of its great impact. If the stamping die quenching temperature is too high, the quenching method and time unreasonable, as well as the tempering number and temperature, elbow elbow between the improper selection, will lead to damage to the mold into the stamping production. Blanking hole size or depth of the design is not enough to easily block the slot, resulting in blanking plate damage. Spring force design is too small or high-set sets of high, will break the spring, blanking board tilt. Resulting in overlapping punching, damage to parts. Improper fixing of the punch or insufficient strength of the screw. Will cause the punch to fall or break.
2, stamping die used, the location of parts, such as the wrong direction or bolt fastening bad. Work height adjustment is too low, guide column lubrication insufficient. Feeding equipment is faulty, abnormal presses, etc., will cause damage to the stamping die. If there is foreign material into the stamping die, the workpiece overlap, waste blocking and other conditions are not dealt with in time to continue processing production, it is easy to damage the mold blanking plate, punch, under the template and guide column.
