The invention discloses a multi-step flanging machine and a barrel flanging method, and relates to the field of thin-wall metal closed barrel machining, and the multi-step flanging machine comprises a mechanical part, a driving part and a control part; the mechanical part comprises a female die, a stripper plate and a male die; the female die is fixedly arranged, the male die penetrates through the stripper plate and is movably matched with the stripper plate, and the stripper plate and the male die can move back and forth relative to the female die. The end face of the female die is provided with a groove structure used for forming a turnup, and the end face of the male die is provided with a protruding structure used for correcting the shape of the turnup. The driving part is used for driving the stripper plate and the male die to move; the control part is used for controlling the driving part to operate. The pipe fitting flanging device has the advantages that the pipe fitting is corrected in the flanging
