ABSTRACT:
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.
In the operation of indirect extrusion presses it has been the normal practice to employ a composite die assembly consisting of a die and outer encircling die ring. After completion of the extrusion operation the die ring is removed from the back of the container and either the same die ring or a second one is placed back on the die after the die or the container has been moved to position the die at the front of the container.
