Abstract: Metal plastic forming processes and equipment that provides a flexible skew rolling mill with dual-rotatable-shafts, including a base unit, a guide unit, two rollers, two servo main-shaft systems, a roller distance adjusting mechanism, two tilt angle adjusting mechanisms, a cooling system and a numerical control system. The two servo main-shaft systems are mounted under the support of the two beds, thereby driving the two rollers to do rotation motion; the roller distance adjusting mechanism drives the two beds, thereby enabling the two rollers to do synchronous centering and radial feed motion; the two tilt angle adjusting mechanisms drive the servo main-shaft systems respectively to rotate around a horizontal rolling center line and enable the two rollers to do tilt angle adjustment motion; and the numerical control system controls a rotating speed, radial feed and tilt angle adjustment of the two rollers, such that skew rolling mills and rollers of the same dimensions and specification can form shaft parts of different dimensions and specifications by flexible skew rolling. The flexible skew rolling mill with dual-rotatable-shafts has the advantages that the beds are synchronously centered and radial feed, the strength of the beds is high, the mounting and debugging are convenient, flexible production can be realized and the like such that the flexible skew rolling mill has broad prospects of being applied to the field of forming large-diameter shaft parts with diversified specifications.
