Abstract

PURPOSE: To obtain the title device of simple structure and of low cost capable of cutting perpendicular part of a work with certainty and without any trouble by utilizing the rocking movement which occurs at the lowering of the cope of the oscillation cutter blade which constitute a perpendicular part of the cutter at a cope.
CONSTITUTION: Oscillation cutter blade 9 is maintained by the stopper 13 at a position remote from the fixed cutter blade 6 of the cope 6 by the force of the spring 10 before cutting operation, and at the cutting operation, part 1a is cut by the scissors action with the sequence as below: (a) together with the lowering of the cope 2, the lower edge of the oscillation cutter blade 9 contacts with the tilted face 11a of the cum 11 being fixed at the drag 3, (b) the cutter blade 9 slides and oscillates toward the direction approaching the fixed cutter blade 6 along the tilted surface 11a resisting against the force of the spring 10, and (c) thru this movement, the cutter blade 9 hits against the perpendicular part 1a of the work 1 while the cutter blade 9 is maintaining a tilted posture, and cuts the part 1a by the same function as of scissors. Portions of the work 1 other than the portions 1a are cut by the fixed cutter blade 6 of the cope 2 which comes down upon them.
