The method comprises the steps of preprocessing a copper alloy cylinder, then carrying out rotary hot-working forming through a numerical control hot-spinning machine, inputting a detection feedback system aiming at the surface emissivity of the copper alloy cylinder, setting the temperature required by hot working to be 700 plus 900 ℃, and controlling the switch of a heating torch through a set temperature range to enable the cylinder to be always in a set temperature range in the hot working process, thereby realizing the automatic temperature control closing-up forming of the seamless copper alloy gas cylinder. The method and the device solve the problems of defects such as air holes, cracks and the like generated in the welding process of the gas cylinder; the efficiency of the product is greatly improved; the performance of the product can be effectively ensured. The copper alloy gas cylinder can be molded by further processing after being automatically closed, and the processing technology is simple and high in precision.
