Abstract

The corrugated fin production equipment is capable of easily separating a corrugated fin having high ribs from a die after forming the ribs. The corrugated fin production equipment comprises: a lower block; an upper block being moved to and away from the lower block; the die being provided to the lower block and having a concave section; a punch being inserted into the concave section so as to form the rib when the lower block and the upper block are closed; and a movable die constituting a part of the die including the concave section, the movable die being upwardly moved above other parts of the die so as to lift a part of the corrugated fin, in which the rib has been formed, from the underside after the lower die and the upper die are closed to form the corrugated fin.
