  • Publication number: 20220088664
    Abstract: The present invention discloses a method for coreless spinning of a large-ratio multi-variable-diameter hollow shaft, belonging to the field of spinning. The present invention includes following steps: S1: clamping a blank in a lower die unit, driving the workpiece to rotate, causing a rough spinning wheel and a fine spinning wheel to be in contact with the workpiece for staggered spinning, and performing curved reciprocating feed spinning via point contact to form a roughly-spun blank; S2: shifting the rough spinning wheel and the fine spinning wheel, causing shaping spinning wheels to be in contact with the workpiece for shaping spinning, and subjecting the shaping spinning wheels to linear contact shaping and fine spinning only in a radial direction, to obtain a finely spun blank. The present invention solves the problems of high machining difficulty and poor molding quality of hollow shafts in the prior art.
