Abstract
A horizontal metal extrusion press has a tool cassette (13) for a tool set composed of a die (134), a die holder (32) and at least one pressure ring (36), displaceable horizontally along guide rails (10,11) transversely to the press axis between an extrusion position (P) on the press axis and a changing position (W) spaced horizontally from the press axis, and replaceable by a second cassette in the changing position. The cassette has an upwardly open U shape to receive the tool set. A locking piece (14) for retaining the tool set can move in a vertical guideway (22) in the upper guide rail (10), to an upper position above the opening of the cassette and to a lower position inside the opening for closing the opening. The cassette opening has an internal bead (29), and the die holder has a corresponding annular groove. The locking piece is guided on the beads along the sides of the cassette opening.
