Metal pipe heating anti-oxidation conveying integrated device and hot gas bulging process

The invention belongs to the technical field of metal plastic processing, and particularly relates to a metal pipe heating anti-oxidation conveying integrated device and a hot air bulging technology.The metal pipe heating anti-oxidation conveying integrated device comprises a carrying robot body, a tooling, a heating power source, a heating system and an air knife system, and the heating power source is electrically connected with the heating system; the air knife system is arranged on a gripper of the transfer robot body, the air knife system is of a cavity structure provided with an opening, gas formed by jetting of the air knife system forms an air curtain to seal the opening, and the tooling and the heating system are both arranged in an inner cavity of the air knife system. The equipment space is small, the heating amount and the nitrogen usage amount are reduced, energy consumption is reduced, the number of stations is reduced, the carrying time is saved, the cost is low, and the anti-oxidation effect o
