Cross wedge rolling mechanism, device and method for rolling laminated shaft

Abstract

A cross wedge rolling mechanism comprises a drive mechanism and two paralleled and opposed cross rolling moulds; the drive mechanism is in transmission connection with at least one cross rolling mould and drives the cross rolling mould to move; a contact surface in contact with the laminated shaft is disposed on the cross rolling moulds, wherein a pre-squeezing stripe protruding out of the contact surface is disposed on the contact surface of at least one cross rolling mould; a shaping wedge protruding out of the contact surface is disposed on the contact surface of at least one cross rolling mould; an included angle of an extending direction of the pre-squeezing stripe and a moving direction of the cross rolling mould is limited; the pre-squeezing stripe is disposed in front of the shaping wedge such that the laminated shaft sequentially runs over the pre-squeezing stripe and the shaping wedge during moulding.
