Analysis of the Causes of the Burst of the Stamping Die

During the production and processing of stamping dies, some problems may occur, such as bursting of stamping dies, which is also a relatively common situation. There are many reasons for the bursting of the stamping die, but the stamping factory can analyze the specific problems according to the actual production practice, which can effectively control the occurrence of the problems. We can refer to the following reasons. 1. The blanking is not smooth. There is no demagnetization treatment before production and no return pin; there are jammed materials such as broken needles and broken springs during production; when assembling the mold, there is no leakage or rolling blocking of feces, stepping and blocking of feces, this is common, the master of assembly If you are not careful, such as when there are many blanking holes, or when the mold has cushions, this situation is easy to occur. 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, there is no backing board. 3. Improper wire cutting treatment The wire cutting gap is not handled properly, and there is no effect on the metamorphic layer of the clear angle and the wire cutting. The cutting edge of the die is mostly processed by wire cutting, and a reasonable electrical gauge should be selected to minimize the depth of the metamorphic layer. 4. Heat treatment: deformation caused by improper quenching and tempering process 　Practice has proved that the thermal processing quality of the mold has a great impact on the performance and service life of the mold, which can be known from the analysis and statistics of the causes of mold failure. 5. Selection of punch equipment 　The punch tonnage, the punching force is not enough, and the die adjustment is too deep. The accuracy and rigidity of stamping equipment (such as presses) have an extremely important impact on the life of the die. The stamping equipment has high precision and good rigidity, and the life of the die is greatly improved.
