Abstract
An arrangement for obtaining proper alignment of parts and proper sealing of parts in an extrusion press having an offset supporting shaft rotatably carrying a container holder assembly and two or more containers into which heated billets are placed to be brought to the extrusion station. A set of aligning keys diametrically opposite each other on both ends of each container engage with a corresponding set of keyways in a sealing member and a die slide respectively. Clearances provided between the containers and the container holder and between other keys and keyways used to mount the containers in the container holder allowing the containers to be moved in a direction to enable the sets of aligning keys to engage the keyways in the die slide and the sealing member to align the containers when in the extrusion station to other components of the press and to maintain these three elements in the aligned position with respect to the slide and sealing member, and in addition, the sealing member is guided on the same guideways as the main crosshead carrying the extrusion stem and mandrel.
