A study of edge characteristics of sheared and bent steel plate

Journal of Applied Metalworking volume 3, pages 381–390 (1985)Cite this article

Abstract

The objective of this investigation was to gain an understanding of the phenomenon of edge crack formation during the bending of plate cut to size by shearing. The stages of sheared edge creation as well as the effect which blade gap and dullness have on the sheared edge properties were studied using the microhardness scanning technique.

The material used throughout this experimental work was AISI 1020 hot-rolled steel 6.4 mm (0.25 in.) thick. Bending of actual sheared edges was performed to evaluate the effect of shearing process control and subsequent sheared edge treatments prior to bending on the magnitude of edge cracking. Significant results of this study show that shearing blade gap and dullness affect the magnitude of edge cracking. The presence of a burr on the sheared edge did not significantly affect the magnitude of edge cracking. Annealing of the sheared edge eliminated edge cracking completely.
