This disclosure pertains to a method and device for changing a die ring to and from a die in an indirect extrusion press. Once the die-die ring assembly is exposed from the container of the press, the changing device consisting of a rotating arm having opposed relatively movable jaws is caused to engage the die ring and remove it from the extrusion axis of the press, and after treatment, if necessary, to return it to the extrusion axis and place it on the die.
