Abstract
PURPOSE: To reduce the cutting-off load upon a cutting-off member and shear a hollow piece such as a pipe well, by cutting a groove on the hollow piece and thereafter cutting off the piece at the cut groove in a method and a device for shearing the hollow piece.
CONSTITUTION: Circular saws 20 are moved toward a continuously traveling round pipe A synchronously therewith to cut grooves C of prescribed depth on the round pipe A. A cutting-off member B is moved toward the cut grooves C synchronously with the round pipe A and thrusted into the groove C to cut off the round pipe A. Since the pipe A is cut off as described above, the cutting-off load upon the cutting- off member B is reduced and the round pipe A is prevented from buckling at its cut- off portion.
