It is a very common phenomenon for metal stamping dies to burst. Generally, metal stamping dies will only burst with a small gap, but in severe cases, stamping dies may be split into several pieces. There are many reasons for metal stamping dies to burst. Die design, Manufacturing materials, metal stamping process and other factors may affect the quality of the mold.

It is a very common phenomenon for metal stamping dies to burst. Generally, metal stamping dies will only burst with a small gap, but in severe cases, stamping dies may be split into several pieces. There are many reasons for metal stamping dies to burst. Die design, Manufacturing materials, metal stamping process and other factors may affect the quality of the mold.
1. Reasons for metal stamping die design
Under normal circumstances, if the structure of the metal stamping die is unreasonable, the strength is not enough, the distance between the knife edges is too close, the number of template blocks is not enough or there is no pad foot, then the die faces a great risk of bursting. The mold design mainly includes the following points:
(1) Nesting and overlapping: The reciprocating feeding nesting method often causes damage to the mold, and if the overlapping value is too small, it will also aggravate the wear degree of the stamping die, so choosing a reasonable nesting method and overlapping value can Extend the life of the mold and avoid bursting.
(2) Accuracy of the guiding mechanism: accurate and reliable guiding can reduce the wear of the mold and avoid the occurrence of gnawing of the convex and concave molds, especially suitable for the use of no gap and small gap blanking dies, compound dies and multi-station progressive dies. In addition, in order to improve the life of the mold, it is necessary to select the correct guide form and the accuracy of the guide mechanism according to the nature of the processing technology and the accuracy of the mold parts.
