Patent ID: 10493511

Abstract:
The objective of the present invention is to provide an apparatus for manufacturing an elbow-shaped duct, comprising: a main body obliquely provided at the upper part thereof; a duct movement guiding part provided to rotate and vertically move; a duct vane forming part including forming jigs symmetrically formed and respectively slid in the opposite directions to be coupled to and separated from each other; a duct vane coupling part including a duct fixing member for guiding the fixing of a duct and a duct vane pressing member for coupling upper and lower vanes of the duct; and a rotary driving part rotatably provided inside the main body, and including an eccentric rotary roller having, at the upper part thereof, a cutting roller for cutting the duct and a forming roller for forming the upper and lower vanes of the duct, thereby enabling the duct to be manufactured, by loading the cylindrical duct on the movement guiding part, as is, and simultaneously performing cutting and forming to correspond to an elbow shape, and thus remarkably reduces manufacturing time.
