Patent number: 10286610Abstract: Joining regions in sandwich sheets having a plastic core layer disposed between two metal cover layers are desirable for purposes of joining sandwich sheets to other components by, for instance, fasteners and/or welded joints. Methods and apparatuses for producing such joining regions in sandwich sheets allow for durably form-fitting and/or force-fitting joints between the sandwich sheets and other components. Some methods may involve displacing plastic material of the core layer of the sandwich sheet out of the region to be joined. A predetermined force may be exerted perpendicular to a surface of the region to be joined when the core layer of the sandwich sheet is heated so that the plastic material of the core layer is softened and at least partially displaced. In turn, the metal cover layers of the sandwich sheet may be brought into contact with one another in the region to be joined.Type: GrantFiled: August 29, 2014Date of Patent: May 14, 2019Assignee: THYSSENKRUPP STEEL EUROPE AGInventors: Azeddine Chergui, Jürgen Goldmann, Mustafa Al

Patent number: 7685857Abstract: A curved extrusion includes a body that has indefinite length and a cross-section, and that is formed to contour and at least one channel cut into the cross-section that is filled with deposited material such that said cross-section of said body is restored. By cutting the channels into the cross-section of the extrusion, the extrusion may be easily formed onto a contoured tool to be curved with lower forming and residual stresses and distortion. By filling the channels with deposited material, the original cross-section and strength of the extrusion can be restored. By adding a transverse stiffener, the strength of the original extrusion may not only be restored but also further improved. By depositing material to create structural features the cross-section of the extrusion may be locally changed. The method for forming curved extrusions of the present invention may be used, for example, to produce T-chords of an aircraft.Type: GrantFiled: May 14, 2008Date of Patent: March 30, 2010Assignee: The Boeing CompanyInventors: Tracy MacDonald-Schmidt, Kevin T.

Patent number: 7654002Abstract: A side member for a vehicle is formed by an extruded profile as well as a closed profile which are both constructed as open profiles with an approximately L-shaped cross-section. On the interior side of the extruded profile, a hollow chamber is situated which is removed in sections along the longitudinal course of the side member in order to achieve a targeted compression behavior (folding) of the side member in the event of an impact of the vehicle. Bushes for receiving the chassis components are inserted in the extruded profile. Like the partial weakening of the hollow chamber, the insertion of bushes takes place before the closing of the side member by connecting the profiles.Type: GrantFiled: July 14, 2005Date of Patent: February 2, 2010Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Cristian Dragoi, Nils Drecoll

Publication number: 20090072506Abstract: According to the invention, in extrusion molding of a control arm of aluminum, control arm is manufactured by a variable curvature extruding process that simultaneously form straight sections and a curved section in extruding a raw material, without pressing forming that is accompanied by solution heat-treatment for forming a carrier fastening end and a bush fastening end at both ends of control arm. Therefore, since the press forming that is required in the extrusion molding of control arm is removed, the manufacturing process is simplified and the manufacturing cost is reduce. Further, the entire extrusion profile cross section of control arm has a double-hollow closed cross section to distribute loads, such that durability of a load-concentrated portion of control arm is increased and the loads can be more effectively distributed.Type: ApplicationFiled: September 5, 2008Publication date: March 19, 2009Applicants: HYUNDAI MOBIS CO., LTD., HWASHIN CO., DONGYANG GANGCHUL CO., LTD.Inventors: Gyewon Jang, Woosik Lee, Daeup Kim, Byungcheol Park, Kaehee Oh

Publication number: 20080138163Abstract: A process by which nanostructured monolithic bodies can be produced in a single continuous operation, as opposed to multi-stage deformation processing. The process generally entails continuously producing a chip having a nanostructured microstructure by engaging a solid body with a cutting edge of a tool while the solid body and the cutting edge move relative to each other, and simultaneously extruding the chip in the immediate vicinity of the cutting edge, such as with a constraining member, as the chip is separated from the solid body by the cutting edge to continuously plastically deform the chip and produce a nanostructured monolithic body immediately downstream of the cutting edge. The shape and size of the chip can be simultaneously controlled by the extrusion process so that the nanostructured monolithic body has a predetermined geometry. The nanostructured monolithic body can be in the form of a product suitable for immediate use, or undergo further processing to yield a product.Type: ApplicationFiled: December 6, 2006Publication date: June 12, 2008Applicant: PURDUE RESEARCH FOUNDATIONInventors: Wilfredo Moscoso, James B.

Patent number: 7340978Abstract: A method for manufacturing a rotary tool for chip removing machining with at least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the mixture body by chip-removing machining. When the chisel is displaced away from the mixture body, a non-fluted shaft portion is formed. By rotating the mixture body while contacted by the chisel, a helical chip flute can be formed. Alternatively, the body could be twisted after a straight flute has been formed, whereupon the flute becomes helical.Type: GrantFiled: July 2, 2004Date of Patent: March 11, 2008Assignee: Sandvik Intellectual Property ABInventors: Jören Kugelberg, Roine Ericsson, Jonathan Fair, Anders Micski

Patent number: 7328600Abstract: A process and apparatus for extruding aluminum into products, wherein aluminum logs are first heated to a predetermined temperature in a furnace, then are cut into billets of predetermined lengths, and then the billets, while still hot, are extruded into predetermined products in an extruder. In the process, the logs are cut into billets with a cross cut circular saw immediately after the logs are heated and before the logs are permitted to cool to a temperature below a suitable extruding temperature. The circular saw is cooled and lubricated during the cutting to as to restrain the saw from sticking in the heated aluminum and so as to maintain the temperature of the log at the cut within a predetermined range wherein the aluminum is relatively easy to cut and waste is minimized.Type: GrantFiled: May 5, 2006Date of Patent: February 12, 2008Assignee: Belco Industries, Inc.Inventor: Thomas F.

Patent number: 7219522Abstract: 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.Type: GrantFiled: July 25, 2003Date of Patent: May 22, 2007Assignee: Taisai Kako Co., Ltd.Inventors: Yuji Maeda, Sigetomi Miyoshi, Takahiro Yamaguchi
