Abstract
A cutting device for a thin metallic plate is provided which shortens time for shaping or the like on a cut edge to improve manufacturing efficiency, and increases the life of a cutter. The cutting device for cutting a thin metallic plate W with a predetermined width includes a shearing cutterwhich is made of a metal having a higher hardness than the thin plate W and has a blade angle of 50 to 90°. A contacting memberis provided which includes a groovefacing the shearing cutterand makes contact with the back side of the thin plate W. In the groove, an interval a between upper edgesandof inner wallsis set at 15 to 30 times a thickness b of the thin plate W. A depth c of a deepest portionin the grooveis set at one to three times the thickness b of the thin plate W. The inner wallsof the grooveinclude curved surfaces, each of which has a curvature radius of 15 to 50 times the thickness b of the thin plate.
