Abstract
One or more hollow billets are loaded onto an elongate mandrel bar for extrusion. The billets are 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.
Claims4
A method for continuously extruding a plurality of billets, the method comprising:
- transporting, along a non-rotating mandrel bar, the plurality of billets from a first end of the mandrel bar to a second end of the mandrel bar;
- and
- extruding the plurality of billets by pressing each of the plurality of billets through a rotating die, wherein friction from the rotation of the rotating die against the plurality of billets is the only source of heat for deforming the plurality of billets;
- wherein a mandrel bar tip is positioned within the rotating die at the second end of the mandrel bar.
