SHEAR METHOD OF FORMING BLADE IN SHAPE AND MAKING BOTH SHEAR DROP SURFACES

摘要

PROBLEM TO BE SOLVED: To form a blade in shape so that a surface of a shorn material is molded as a shear drop surface in both the surfaces. ;SOLUTION: When a material is shorn, a shear surface is made in a burr surface and a shear drop surface, so as to require the burr surface to be changed into the shear drop surface. Consequently, by forming a blade in shape, after the shear drop surface is made in a shorn material, shear work is performed so as to be successively advanced. A device is suited for, for instance, an object with a shear drop surface required for a surface, small object and a continuous work object like a nameplate.;COPYRIGHT: (C)1997,JPO
