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.
Claims17
An extrusion press system comprising:
- a mandrel bar having a first end and a second end, the first end for receiving a billet having a hole therethrough and the second end coupled to a mandrel bar tip;
- a plurality of cooling elements configured to be clamped to the mandrel bar, each of the plurality of cooling elements having a respective port through which cooling fluid is delivered into an interior of the mandrel bar for cooling the mandrel bar tip, wherein at any given time at least one but fewer than all of the plurality of cooling elements are clamped to the mandrel bar;
- a plurality of gripping elements configured to grip the mandrel bar, each of the plurality of gripping elements comprising moveable grips for securing in place and preventing rotation of the mandrel bar, wherein at any given time at least one but fewer than all of the plurality of gripping elements are gripping the mandrel bar;
- and
- a rotating extrusion die, rotating at a speed between 200 RPM and 1000 RPM, configured to receive the billet from a centering insert having a frictional surface that frictionally engages the billet to prevent the billet from rotating prior to entry of the billet into the rotating extrusion die,
- wherein the mandrel bar tip is positioned within the rotating die.
