In the stamping process, if there is insufficient mold strength design


In the stamping process, if there is insufficient mold […]

In the stamping process, if there is insufficient mold strength design or uneven force, the mold is poorly guided, tilted, or there is foreign matter between the templates, the mold clamping will be inflexible or even stuck. At this time, it is necessary to stop the production, find out the cause of the card, and eliminate the fault. Otherwise, the fault will be enlarged, resulting in damage to the mold.
Whether the metal stamping die manufacturing material and its heat treatment process are suitable, has a great influence on the quality of the die. 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 are not suitable, and the elbow of the elbow pipe is not suitable. Improper selection will result in damage to the mold after it enters the stamping process, and the quality of the metal stamping parts is damaged.

During the processing of the mold, if foreign matter enters the stamping die, the parts overlap, the waste is blocked, etc., but it is not processed in time, and the mold is still used, it is easy to cause the blanking plate, the punch, the lower template and the mold. The guide post is damaged.

When the size or depth of the die blank hole is not enough, it is easy to 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 fixing of the punch or insufficient strength of the screw can cause the punch to fall or break and damage the mold.

When the mold is in use, the position and orientation of the parts are incorrectly installed or the bolts are not fastened. If the working height is adjusted too low, the guide column is insufficiently lubricated, the feeding equipment is faulty, and the press is abnormal, etc., the stamping die may be damaged.
