The present invention relates to a manufacturing apparatus for an elbow pipe to connect a duct, which enables an elbow pipe used for connecting and assembling a duct for a pipe to be semipermanently used with excellent chemical resistance by applying an appearance of a metal material and an inner pipe structure of synthetic resin material quality, and enables the elbow pipe having different material quality to be easily manufactured. To achieve this, according to the present invention, the manufacturing apparatus for an elbow pipe comprises: a body unit (100) wherein a stage (110) is provided; a transfer unit (200) wherein a gripper (220) is provided; an inner pipe press unit (300) installed on the stage (110); a heating contact unit (400) enabling an inner pipe (13) to be in contact with an inner circumferential surface of an outer pipe (11); a heating unit (500) heating an end (13a) of the inner pipe protruding to an end (11a) of the outer pipe at a predetermined temperature; and a pressurization bending unit (600) bending and forming a second bending unit (15b). |
