Hardware tells you the cause of the explosion of precision stamping parts?

It is a very common situation that the mold template of precision stamping parts bursts, but when it is serious, a template is divided into several pieces at once. There are many reasons for the direct cracking of the template, from the purchase of materials to the mold design The stamping operation process can affect it. The following author sorts out the reasons for the bursting of precision stamping parts. 1. The blanking of precision stamping parts molds is not smooth. There is no demagnetization treatment before production, no return pin; there are broken needles and springs and other jams in the production; there is no leakage, or rolling and blocking of feces when assembling the mold, this is the point It is common that if the assembling master does not pay attention, such as when there are many blanking holes, or when the mold has cushions, this situation is prone to occur. 2. The design process of precision stamping die. The die strength is not enough, the knife edge distance is too close, the die structure is unreasonable, and the number of template blocks is not enough and there is no backing board. 3. Heat treatment of precision stamping parts: improper quenching and tempering process produces deformation. 4. Improper wire cutting treatment of precision stamping parts. Wire cutting is improperly processed, and the gap between the wire cuttings is not handled properly, and there is no effect on the deteriorating layer of the corner cleaning and the wire cutting. The cutting edge of the die is mostly processed by wire cutting. Due to the thermal effect and electrolysis of the wire cutting process, a certain thickness of metamorphic layer is produced on the surface of the mold, which causes the surface hardness to decrease, and the appearance of micro cracks, etc., makes the wire cutting die prone to early wear, which directly affects the blanking gap of the die. Keeping and cutting edges are easy to chip and shorten the service life of the mold. Therefore, in the online cutting process, reasonable electrical standards should be selected to minimize the depth of the metamorphic layer. The above are the reasons for the explosion of precision stamping parts. If you need to know more, please consult:
