Extrusion press systems and methods

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.

主权项

1. A method for continuously loading and extruding a plurality of billets, the method comprising:
loading a first billet at a receiving end of an elongate mandrel bar; transporting the first billet along the mandrel bar and through gripping elements that secure in place and prevent rotation of the mandrel bar, wherein at any given time at least one of the gripping elements is gripping the mandrel bar; transporting the first billet along the mandrel bar and through cooling elements that clamp to the mandrel bar and deliver cooling fluid to the mandrel bar, wherein at any given time at least one cooling element is clamped to the mandrel bar; and extruding the first billet to form an extruded material by pressing the first billet through a rotating die rotating at a speed between 200 RPM and 1000 RPM, wherein the first billet is followed by an adjacent second billet that forms a part of the extruded material.
