Duct wing compression unit for elbow type duct manufacturing equipment

摘要

In a process of joining upper and lower wings of a duct, the present invention is advantageous in that a horizontal moving member and a moving pressurizing member can be used to primarily pressurize an upper part of the lower wing of the duct horizontally, is capable of preventing an occurrence of scratches on a lower duct wing by a pressurizing method through two motions by lowering the lower wing of the duct by secondarily pressurizing the lower wing, thereby being capable of manufacturing good-looking products, and has an advantage of being able to produce products with excellent marketability.
