Continuous friction stir and extrusion production method for metal matrix composite and production device thereof

The invention provides a continuous friction stir and extrusion production method for a metal matrix composite and a production device thereof. According to the method and the device, a concave grooveis processed on a straightened matrix metal bar, a reinforcement is added into the concave groove, a composite blank is pressed into an annular groove of an extrusion wheel through a material pressing wheel and is clamped, the blank is driven to move towards a stirring head through rotation of the extrusion wheel, friction stir processing is carried out on the blank in the annular groove betweenthe material pressing wheel and a mold cavity at least once through rotation of the stirring head, the flowing direction is changed after the stirred blank is blocked by a material blocking block, theblank is extruded out from an inner hole of a mold, and therefore a continuous large-length metal matrix composite wire product is formed. 本发明提供一种金属基复合材料连续搅拌摩擦挤压生产方法及其生产装置，在经过矫直的基体金属杆料上加工凹槽并向凹槽中添加增强体，利用压料轮将复合坯料压入挤压轮的环形沟槽并夹紧，由挤
