  • Patent number: 9156072
    Abstract: Disclosed herein is an ultrasonic extrusion apparatus which causes resonance of an extrusion die using ultrasonic vibrations, thus reducing friction between the extrusion die and an extrusion material. The ultrasonic extrusion apparatus has an increased number of ultrasonic vibrators provided around the extrusion die in the circumferential direction to increase the vibration output, whereby when extruding a metal material such as a magnesium material, friction between the metal material and the extrusion die can be reduced, thus improving the performance of the extrusion process (preventing a reduction in an extrusion rate, generation of heat, cracking of a product, errors in measurements, etc.).

    Abstract: An extrusion press comprising a pressure ring (6) having a convex shape rear base (62) resting in a seat (71) of a platen (7). The convex shape is either spherical or truncated cone shaped so as to relieve onto the platen (7) the greatest amount of extrusion pressure exerted on the front face (61) of the pressure ring (6) of the die pack (3). This limits the deformation on the front base (61) and consequently the geometric variations of the extruded profile (5).

  • Publication number: 20140017113
    Abstract: Processes by which bulk forms can be produced in a single continuous operation, as opposed to multi-stage deformation processes that involve a series of separate and discrete deformation operations or stages. Such processes generally entail deforming a solid body using a large-strain extrusion machining technique and deformation conditions that obtain a predetermined crystallographic texture in the continuous bulk form that differs from the crystallographic texture of the solid body.

  • Publication number: 20140000332
    Abstract: Extrusion of feed materials of a high temperature formable non-ferrous metal susceptible to embrittlement during air processing uses an extrusion system having a rotatable wheel and shoe covering part of the length of a groove around the periphery of the wheel to form an arcuate passageway, the shoe having an abutment which substantially closes a second end of the passageway and an extrusion die spaced from the abutment by a die chamber. The process includes pre-heating the feed material to not less than about 390° C. in a chamber defined by a feeder device, maintaining a protective atmosphere in the chamber of the feeder device while the feed material is heated. The pre-heated feed material then is passed to an inlet end of the passageway, and drawn along the passageway, to be forced by the abutment into the die chamber and through an extrusion orifice of the die to provide extruded product.

  • Publication number: 20130243036
    Abstract: In a thermocouple, a pair of thermoelements extend within a protective sheath. The thermoelements are spaced from the sheath by an insulator. The sheath comprises an outer sheath formed from a metal alloy adapted to provide mechanical support and corrosion resistance during use of the thermocouple, typically at elevated temperature. The sheath further comprises an inner sheath positioned between the outer sheath and the thermoelements and formed from a nickel-based alloy containing less than 10 wt % Cr, to prevent diffusion of Cr and/or Mn from the outer sheath to the thermoelements.

  • Patent number: 8516868
    Abstract: Provided is a die for shear drawing capable of performing continuous drawing and shear deformation at the same time. The die for shear drawing includes a material processing channel in which a material is sheared and drawn while passing therethrough, wherein the processing channel includes an inlet path positioned at a front end thereof, and an outlet path positioned at a rear end thereof, when viewed from a movement direction of a material. The inlet path and the outlet path are connected to intersect a central axes thereof at a certain angle, and the processing channel includes a cross-section reduction segment allowing an outlet cross-sectional area of the outlet path to be smaller than an inlet cross-sectional area of the inlet path to thereby draw out a material from an exit of the outlet path with the material filled therein.
