DEVICE AND METHOD FOR MAKING CONTINUOUS SHEAR DEFORMATION CAPABLE OF ENHANCING THE STRENGTH OF A METALLIC MATERIAL AND REMOVING LIMIT TO THE SIZE AND LENGTH OF THE METALLIC MATERIAL

摘要

PURPOSE: Device and method for making continuous shear deformation are provided to make the surface and the grain of the core of a metallic material ultrafine particles and enhance the entire strength of the metallic material to be plasticized, since strong shear plasticity change is made to the surface and core of the metallic material.;CONSTITUTION: A device for making continuous shear deformation comprises a driving die(20), an eccentric die(30), an auxiliary die and a bearing. The driving die enables an eccentric hole(22) to be eccentric to a rotating shaft(a). The driving die is rotatably installed on one side of a main mold(10). The eccentric die comprises an eccentrically processed hole(32) and is installed to be eccentric to the eccentric hole. The auxiliary die forms a processed hole on the central part of the driving die. The bearing is installed between the driving die and the eccentric die.;COPYRIGHT KIPO 2012
