The invention discloses a differential pressure forming method for local large-deformation hollow pieces and belongs to the technical field of manufacturing of metal hollow members. The differential pressure forming method includes steps of firstly placing a pipe billet into a rear die, loading a punch into the pipe billet and sealing; injecting high-pressure liquid to the inner and outer surfaces of the pipe billet at the same time, keeping pressure in the pipe billet larger than the pressure of the outer surface of the pipe billet and forming controllable pressure difference; pushing the punch to axially feed to realize material supplement by the aid of a hydraulic cylinder, and enabling the pipe billet to generate local large deformation under the action of inside and outside hydraulic differential pressure; finally, discharging the high-pressure liquid and obtaining a local large-deformation hollow piece. By controlling inside and outside pressure difference of the pipe billet, stress state during local expansion of the pipe billet can be improved, expansion can be sufficiently realized and expansion limit is increased. Hydraulic oil is injected onto the outer surface of the pipe billet, lubricating between the outer surface of the pipe billet and a form cavity of the die is evidently improved, friction is reduced, and axial supplement and final forming are facilitated.
