Abstract
PURPOSE: To eliminate generation of a burr, by forming a shearing bite of certain depth in a sheet material as left in a state of being held in a shearing mold and then reversely applying shearing force to the sheet material thus performing shearing work to the sheet material.
CONSTITUTION: Under a state of holding a sheet material W by a die 3 and pad 8, a punch 6 cooperatively actuated with the die 3 is pressed toward the sheet material W to form a shearing bite in the sheet material, for instance, to about 60W90% thickness of the plate. When the punch 6 is returned, in a state of holding the sheet material cooperatively by a floating die 11, set at a face-to- face position to the punch 6, the pad 8 and the die 3, a shearing bite is reversely applied to the sheet material, then the sheet material is cut off without causing a burr.
