Abstract: A machining oil applying apparatus that applies machining oil onto a thin metal plate that is being conveyed toward a press apparatus includes: an upper surface applying unit that is impregnated with machining oil, contacts an upper surface of the thin plate and applies the machining oil onto the upper surface; a lower surface applying unit that is impregnated with the machining oil, contacts an lower surface of the thin plate and applies the machining oil onto the lower surface; and an applying unit moving portion that causes the upper surface applying unit and the lower surface applying unit to move reciprocally in a direction perpendicular to a conveying direction of the thin plate, wherein the upper surface applying unit and the lower surface applying unit always move in respectively opposite directions perpendicular to the conveying direction.

Abstract: The equipment for cutting a corrugated fin is capable of sufficiently cutting a corrugated fin having high ribs. The equipment comprises: a movable blade moving into a rib of a corrugated fin and cutting the corrugated fin; and a fixed blade being fixed on the opposite side of the corrugated fin from the movable blade, the fixed blade cutting the rib with the movable blade. A tip section, which has a cutting face capable of cutting the rib with the fixed blade, is provided to a front end of the movable blade. A supporting block supports one of outer faces of the rib, which corresponds to the tip section of the movable blade, and is biased upward, thereby the supporting block is moved downward together with the cut rib, which has been cut and pushed downward by the movable blade, with continuously supporting the outer face of the cut rib.
