    摘要： Systems, devices, and methods are described for extruding materials. In certain embodiments, one or more hollow billets are loaded onto an elongate mandrel bar and transported along the mandrel bar to a rotating die. The billets are transported through fluid clamps, which engage the mandrel bar and provide cooling fluid to the mandrel bar tip, and through mandrel grips, which engage the mandrel bar and prevent the mandrel bar from rotating. One or more press-rams advance the billets through a centering insert and into the rotating die. A quench assembly is provided at an extrusion end of the extrusion press to quench the extruded material. A programmable logic controller may be provided to control, at least in part, operations of the extrusion press system.

    摘要： A process for extruding a section or the like body from an ingot is such that an ingot is introduced into a bore of a container and, by means of an extrusion stem, is fed in the direction of extrusion into a shape-giving opening in a die. Before the ingot enters the die opening, it is pushed out of the container by an amount corresponding to the width (t) of a collar whereupon a disk-shaped slice is sheared off the free end of the ingot and removed. The free end of the ingot is then pushed onto the die opening. In order to carry out this process a shearing tool is provided after the end of the container facing the die and a moveable shearing blade positioned over that entrance to the container bore The disk-shaped slice should preferably be sheared away together with a residual butt of the previously extruded ingot which faces away from the die. To that end a shearing tool with two shearing blades is provided and can be moved radially with respect to the longitudinal axis (A) of the container bore.

    摘要： Apparatus for the continuous extrusion of metals in which feed is introduced into two (or more) speed apart circumferential grooves in a rotating wheel (or rotating wheels) to contact an arcuate shoe portion and abutments extending into the grooves. The feed is constrained by the abutments to flow through frusto-conical exit apertures of cone angles in the range of 5.degree.-45.degree. in the shoe portion to a chamber which may also be of the divergent frusto-conical form, and is extruded as relatively thin-walled, large-cross-section products. Mixer plates are profiled to distribute flow evenly from the apertures to around the die opening. An extrusion die body for cylindrical extrusions is located and axially centered by set screws. Where an even number of grooves are utilized, an extrusion mandrel may be secured to the shoe portion by a bolt positioned centrally of the grooves and having a passage for injection of lubricant or oxidation inhibiting fluids. Since the volume feed rate is enhanced and the distance travelled by the material from the grooves is reduced, friction losses and the likelihood of discontinuities arising in extrudate products of relatively large hollow cross-section are thereby reduced.
