The invention relates to the technical field of metal plastic forming technologies and apparatuses, and provides a double-rotation-shaft skew rolling mill. The double-rotation-shaft skew rolling millcomprises a base unit, a guide plate unit, a left machine frame rotation shaft, a right machine frame rotation shaft, a left machine frame, a right machine frame, a left synchronous gear, a right synchronous gear, a left roll system, a right roll system, a left roll, a right roll, inclination angle adjusting bolts and a roll spacing adjusting unit; the guide plate unit is fixed to the top of the base; the two machine frame rotation shafts are symmetrical about the axis of a blank; the left synchronous gear and the right synchronous gear are engaged, so that the two machine frames are synchronously centered and pressed downwards; the two rolls are coaxially fixed through the two roll systems; the inclination angle adjusting bolts are used for adjusting the inclination angles of the two rolls; the roll spacing adjusting unit is used for adjusting the opening degree of the two machine frames to change the roll spacing of the two rolls; and under the action of friction force of the rolls/the blank, the blank is subjected to skew rolling between the two rolls to be formed. The double-rotation-shaft skew rolling mill has the advantages that synchronous centering and pressing down can beconducted, a vertical center line does not skew, the strength of the machine frames is high, and installing and debugging are easy, and can be applied to mass skew rolling forming of middle and small-sized parts.
