Abstract
A press operated by the reverse method comprising a fixed tubular die casing defining a pressing axis, a main jack operative to displace a cross beam supported for displacement along the pressing axis, a displaceable holder disposed between the cross beam and the tubular die casing and having a bore disposed along the pressing axis for receiving a billet to be pressed. The bore has open ends and the holder is capable of fitting over the die casing by axial displacement thereof. A closure member is carried by a slide for closing one end of the bore in the holder; the slide is displaceable on the cross beam transversely with respect to the pressing axis. A support is slidably mounted parallel to the slide and is carried by an auxiliary cross beam which is slidably mounted on the main cross beam for movement parallel to the pressing axis. The support and the slide are simultaneously displaceable under the action of a jack or other suitable device. A rod is connected to the support and is slidably mounted axially in the slide for operating auxiliary members slidably mounted in the slide.
