AI Technical Summary

Technical Problem

Existing metal stamping forming defect prediction technologies fail to identify irreversible failures in material deformation paths, cannot provide effective early warnings before defects appear, and lack the ability to continuously characterize the evolution process of material deformation degrees of freedom.

Method used

By collecting stamping parameters and forming response data in real time, a separability index is constructed. Based on the continuous downward trend of the separability index, it is determined whether the material deformation degree of freedom has shrunk, and the material is identified as entering an irreversible failure path.

Benefits of technology

It enables the identification of implicit stages of material deformation degree of freedom loss, provides early warning of irreversible failure paths, improves the predictability and reliability of prediction, and avoids misjudgment based on explicit defect signals.

Abstract

The application discloses a hardware forming defect prediction method and system based on stamping parameters, and particularly relates to the technical field of hardware forming defect prediction, and comprises the following steps: acquiring stamping parameters corresponding to each stroke in a hardware forming process and forming response data corresponding to the stamping parameters, combining the stamping parameters and the forming response data to form a stroke data entry, and writing the stroke data entry into a cache queue of edge calculation; reading a plurality of continuous stroke data entries in the order of strokes from the cache queue of edge calculation, and calculating the difference value of the stamping parameters in adjacent stroke data entries to obtain parameter change data; collecting the stamping parameters and the forming response data in real time in continuous strokes, constructing a separability index reflecting the sensitivity of the material to the parameter change, and judging whether the deformation freedom of the material is contracted according to the continuous downward trend of the separability index, so as to identify the state of the material being forced to enter an irreversible failure path before the appearance of the explicit defect.
