摘要

PURPOSE: A corrugated fin cutting device is provided to prevent a cutting fail and damage to a movable blade because the outer side of a rib is supported with a support block.;CONSTITUTION: A corrugated fin cutting device comprises a movable blade(32), a fixed blade(34), and a support block(40). The movable blade moves into a rib(12) of a corrugated fin in order to cut the corrugated fin. The fixed blade is fixed opposite to the movable blade around the corrugated fin and cuts the rib by cooperating with the movable blade. The movable blade has a tip portion(31) with a cutting face(32a) that cuts the rib by cooperating with the fixed blade. The support block supports one of exterior surfaces of a rib corresponding to the tip portion of the movable blade and is elastically pressed upward to support the rib pushed down by the movable blade and move downward with the cut rib.;COPYRIGHT KIPO 2012
