The invention relates to a radial and axial roll-forming method for a large internal-stage annular piece. The method comprises the following steps of: (1) making a blank, namely performing hot-forging, upsetting, punching and slug-stamping on a bar material, and thus obtaining an annular piece blank for rolling; (2) designing a roll hole pattern, namely determining the size of the roll hole pattern according to a roll linear speed, an equipment parameter, a roll deformation condition and the size of the annular piece blank, and determining the size of the axial roll hole pattern according to the roll linear speed, the equipment parameter, the annular piece blank and the size of the annular piece blank; and (3) roll-forming, namely putting the obtained annular piece blank on an annular rolling machine for rolling, controlling an upper conical roller and a lower conical roller to move backwards in real time during rolling to make the bottom end of the annular rolling machine always contact outer diameters of the upper end face and the lower end face of the annular piece, controlling the rolling process by rationally distributing a feeding speed and a feeding amount according to three stages, namely pre-rolling, rolling and shaping rolling, and when the outer diameter of the detected annular piece reaches a preset value, finishing the rolling process. The method has the characteristics of high production efficiency, low production cost and high product quality.
