1.Check whether the manufacturing material of the stamping die is suitable, and whether the corresponding heat treatment process is reasonable. The heat treatment process of the stamping die material usually has a great influence on it. If the quenching temperature of the stamping die is too high, the quenching method and time are unreasonable, and the number of tempering and temperature, and the improper selection of the elbow between the elbow fittings, the mold will be damaged after entering the stamping production.
The size or depth of the blanking hole is not designed enough to easily block the slot and cause the blanking plate to be damaged. If the spring force design is too small or the height is not equal, the spring will break and the blanking plate will tilt, causing overlapping punching and damage to the parts. Improper punch or insufficient screw strength. Will cause the punch to fall or break.
2.When the stamping die is used, the position and orientation of the parts are incorrectly installed or the bolts are not fastened. The working height is adjusted too low and the guide column is insufficiently lubricated. If the feeding equipment is faulty, the press is abnormal, etc., the stamping die will be damaged.
If the foreign matter enters the stamping die, the overlap of the parts, the blockage of the waste, etc., it is not processed in time, and the processing and production are continued, and the blanking plate, the punch, the lower die plate and the guide post of the die are easily damaged.
