Abstract
A continuous shear deformation apparatus comprises: a roller for pushing a metal sheet to be processed into dies; the dies having an inlet for introducing a metal sheet, a shear deformation zone for shear-deforming the sheet, and an exit; and a control unit for controlling a gap of the dies exit depending on the compressive stress generated at the metal sheet while the metal sheet passes through the shear deformation zone of the dies. The compressive stress generated at the metal sheet becomes constant when the metal sheet is shear-deformed, and thereby the thickness of the metal sheet is uniformly controlled in a longitudinal direction.
