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： It is an object of the present invention to provide a novel aluminum tube of an oval cross section that has a wider range of applications and added values. A disk-shaped metal slug (21) is impact-extruded with the use of a die (14) and a punch (13) each having an optimally designed structure to form a metal tube (T) integrally including a mouth, a shoulder and a body of an oval cross section. A hem portion of the oval body of the tube (T) thus formed and hardened by the impact extrusion is once deformed into a circular shape, and then trimmed off by a turning operation.

摘要： This invention discloses a monolithic aluminum foot for use with a tractor trailer landing gear. The monolithic foot has a pocket that is adapted to receive the landing gear and one or more support members extending radially outward from the walls of the pocket. The support members are integrally extruded with the walls of the pocket during the extrusion of the foot. The foot and the landing gear have one or more aligned apertures that are adapted to receive one or more locking members, which lock the foot to the landing gear. This invention also discloses an extrusion method of fabricating monolithic foot in tractor trailer gear.

摘要： An improved cooling system is provided in a piercing mandrel used in extruding tubular material made of metals having extruding temperatures above the annealing temperature of H13 tool steel such as brass, copper and the like. The piercing mandrel has a replaceable tip fitted on the end of the stem portion for the mandrel. A cooling channel system is provided at the distal end of the stem and comprises a disperser for dispersing cooling fluid in equi-distant, multi-radial directions as the cooling fluid flows out of the stem distal end. An annular channel is provided at the perimeter of the mating faces of the bore in the tip and the stem distal end and which is in communication with the disperser to direct radially cooling fluid annularly of the perimeter of the mating faces at the stem distal end. The cooling channel system further comprises about the perimeter of the stem distal end a plurality of equi-distant, longitudinally directed channels which are in communication with the annular channel. Cooling fluid flows from the annular channel longitudinally of the tip along the longitudinal channels. The stem distal end has a cooling fluid outlet device for collecting cooling fluid and directing spent cooling fluid outwardly along the stem.

摘要： A press for hydrostatic extrusion of tubes includes a high pressure cylinder axially displaceable in a press stand with a die insertable into the cylinder and a pressure generating punch insertable into the cylinder to generate the pressure for extrusion. A mandrel is carried by a rod which passes through the pressure generating punch. Seals are provided between the mandrel and the pressure generating punch and between the pressure generating punch and the pressure cylinder. These seals are so located that during the actual extrusion they are arranged in the same transverse plane.
