Wherein the punching female die and/or the punching male die which are replaced each time are sequentially increased in number.
For example, after the first group of punching sample sheets are obtained, the punching female die with larger size is replaced, and the steel plate sample sheets with the same preset thickness specification are tested according to the steps from S1 to S4, so that the second group of punching sample sheets are obtained. And continuously increasing the size of the punching female die, and repeating the steps from S1 to S4 for testing to obtain a third group of punching sample sheets. Optionally, after the die is replaced for the first time, the punching gap corresponding to the punching die is 20% of the preset thickness.

Further, the quality/quality of the blanking quality of the steel plate sample wafer to be blanked can be determined according to the determined target quantity.
Specifically, the plurality of groups of semicircular blanking sections can be placed under an electron microscope to observe whether each semicircular blanking section has a layering phenomenon in the bright band and the tearing band, and if not, the blanking quality is judged to be good; otherwise, the blanking quality is poor. Or when the target quantity is lower than a first threshold value, determining that the blanking quality corresponding to the steel plate sample wafer to be blanked is good. Otherwise, determining that the blanking quality corresponding to the steel plate sample wafer to be blanked is poor. The first threshold is a value set by a system in a self-defining way, and may be 0, for example. When the first threshold value is 0, it indicates that a delamination phenomenon occurs or does not occur in the semicircular blanking cross section.
