Why does the stamping die template crack?

When stamping die processing operations, sometimes there will be template cracking. This is a relatively common situation. So what is the cause of template cracking? After asking our technicians, the author will briefly introduce you below . 1. The mold material is not good, and it is easy to chip in the subsequent processing. 2. Design process: the mold strength is not enough, the knife edge spacing is too close, the mold structure is unreasonable, the number of template blocks is not enough, and there is no backing board 3. Heat treatment: improper quenching and tempering process Deformation 4. Mold grinding flatness is not enough, resulting in deflection deformation. 5. Selection of punch equipment: punch tonnage, insufficient punching force, too deep under adjustment of the mold 6. Improper wire cutting treatment: drawing wire cutting, wrong clearance, no work Clear corner 7. Unsmooth material removal: no demagnetization treatment before production, no return tip; broken needle or spring and other jams during production 8. Unsuccessful blanking: the blade is straight and the position is too long, and the blanking slope is not enough. Mold leakage and waste holes are blocked. 9. Production awareness: laminated stamping, positioning is not in place, blowing tools are not used, and the template is cracked. The above is the reason for the cracking of the stamping die.
