The invention relates to a rotary reciprocating extrusion device for a superfine crystal magnesium alloy and a processing method, and belongs to the technical field of non-ferrous metal plastic processing. The device and the method can solve the problem that an existing magnesium alloy mechanical property improvement method is not beneficial to batch production. According to the device and the method, a rotating wheel is additionally arranged in the deformation process to enable a cavity of an extrusion mold to rotate to change the extrusion path so as to realize the introduction of the torsion deformation in the extrusion process, then the magnesium alloy undergoes deformation processing through multi-pass reciprocating rotary extrusion, continuous deformation of a magnesium alloy blank is realized, and the magnesium alloy material with fine grains and uniform structure is prepared. According to the rotary reciprocating extrusion device and the processing method, the extrusion mold issimple in structure and easy to process, and is suitable for preparation of superfine crystal products such as the magnesium-based material and other light metal.
