An object of the present disclosure is to provide an elbow-shaped duct manufacturing apparatus in which the height of a forming section is easily adjusted as a duct vane forming part has an up and down detachable structure.

The present disclosure relates to a duct cutting and forming apparatus for elbow duct manufacturing machine, the apparatus including a rotation housing that is provided with a seating groove in a first direction; an eccentric housing that is provided with a cutting roller and a forming roller at both ends, and that is slidably seated inside the seating groove; a rotation drive for applying rotation driving force to the rotation housing; and an eccentric drive for applying driving force for reciprocating the eccentric housing, wherein the eccentric drive reciprocates the eccentric housing as it rotates in both directions within a range not exceeding 180 degrees.

A formation and rotation apparatus for use in forming and rotating interconnected sections of a cylindrical workpiece, including a frame and a head arranged within the frame, the head defining two slots and being operatively rotated via an integral drive assembly. A first slide block is slidably disposed within one of the two slots, and a second slide block is disposed within another of the two slots, each of the first and the second slide blocks include a cutting wheel and a beading wheel for successively forming each of the interconnected sections. An armature having an axis of rotation is also provided, along with a gripping mechanism being operatively connected to the armature. A drive mechanism selectively rotates the armature about the axis of rotation after the gripping means has closed about one of the interconnected sections.
