MANUFACTURING DEVICE FOR HEAT EXCHANGER FIN

摘要

The problem addressed by the present invention is to provide a manufacturing device for a heat exchanger fin that can execute adjustments of the number of punches and penetrating holes or cutout parts in the actual product without slackening a metal band shaped body or striking punches twice. As a solution, a mold (46) is provided with a plurality of punches (75) and a plurality of dies (76) that form a plurality of penetrating holes or a plurality of cutout parts along the feed direction of a metal band shaped body (49);the manufacturing device is provided with a feeding device (50) that feeds the plurality of penetrating holes and cutout parts that have been formed in the feeding direction by one feeding movement; a cutoff device (60) that cuts the metal band shaped body (49) into a prescribed length has cutoff punches (68) disposed in the same number as the number of punches and dies along the feed direction of the band shaped body (49); the manufacturing device is provided with a plurality of cutoff punch drive units (72) that operate each of the cutoff punches (68) individually; and the manufacturing device is provided with a control unit (80) that controls each of the cutoff punch drive units (72).
