Analysis Of Die Failure Caused By Common Failures Of Stamping Dies
Stamping die is a kind of special process equipment that processes materials into parts (or semi-finished products) in cold stamping process, which is called cold stamping die (commonly known as cold die). Stamping is a pressure processing method that uses a mold mounted on a press to apply pressure to a material at room temperature to cause separation or plastic deformation, thereby obtaining a desired part. Mold failures are the most prone to problems in stamping production, often resulting in production stoppages and affecting product production cycles.
Die damage is a common fault problem in stamping production, which is manifested as mold cracking, breaking, and opening. When dealing with mold damage, you must look for the reasons from the mold design, manufacturing process, and mold usage. First of all, it is necessary to review whether the mold manufacturing materials are suitable and whether the corresponding heat treatment process is reasonable. In general, the heat treatment process of the mold material has a great influence on it.
If the mold quenching temperature is too high, the quenching method and time is not reasonable, and the number of tempering and temperature, inappropriate choice between the elbow, will lead to damage after the mold into the stamping production. Blanking hole size or depth design is not enough, easy to make the slot hole blocked, resulting in damage to the blanking board; spring force design is too small or contour sets of unequal height, will spring break, falling plate tilt, resulting in overlapping punching, damage Parts; Improper fixing of the punch or insufficient screw strength can cause the punch to drop or break.
When the mold is used, the installation position, direction, etc. of the parts are incorrect or the bolts are not fastened. Work height adjustment is too low and guide column lubrication is insufficient. Feeding equipment failure, abnormal press, etc., will cause damage to the mold. If foreign matter enters the mold, parts are overlapped, and the waste is not treated in a timely manner, and if the processing is continued, the blanking plate, punch, template, and guide post of the mold may be easily damaged.
Therefore, in the event of a failure, the cause of the mold failure must be found as soon as possible, and reasonable repairs must be carried out in order to ensure normal production.
