Abstract:
Method for producing a component system having a first component with a first component portion and a second component with a second component portion, including the following steps: connecting, in particular welding or soldering, the first component portion, which consists of an aluminum alloy, to the second component portion, which in particular consists of a naturally aged aluminum alloy, a copper alloy or an iron alloy, in particular a steel alloy, so as to form a connection seam; artificially aging the connection seam such that the yield strength of the connection seam is above the yield strength of the first component portion and/or of the second component portion; and deforming, in particular deep-drawing and/or stretch-drawing, the component system.
Abstract:
Provided is a method for manufacturing vehicle body parts, including: rolling a blank such that the blank has two or more regions with different thicknesses; trimming the rolled blank; and performing hot press forming on the trimmed blank, and cooling the trimmed blank. The blank to be rolled has an absorption hole, and a flange protrudes from an edge region of the blank corresponding to a position of the absorption hole. The blank is rolled in two or more different directions.
Abstract:
A yoke housing includes a tubular case and a flange. The tubular case is formed from a metal sheet in a drawing process. The flange is formed at an end of the tubular case. The flange has a width in the lateral direction that is equal to the outer diameter of the tubular case. The flange has a base including beads and a thick portion. Each of the beads is formed by compressing the base. A portion of the base in which the beads are not formed defines a thick portion. The thick portion is located at a middle portion of the flange in the lateral direction. The beads are located on opposite sides of the thick portion in the lateral direction.

Abstract:
A mold for hot stamping is disclosed. The mold for hot stamping according to an exemplary embodiment of the present invention may include an upper mold and a lower mold so as to stamp a heated blank having a welding portion. A recess may be formed at an upper forming surface in the upper mold corresponding to the welding portion of the blank and may define a cooling space between the recess and the blank such that a cooling fluid directly cools the welding portion of the blank after the blank is stamped.

Abstract:
A one-piece seat back frame for use in a vehicle seat assembly including a first side portion, a second side portion, an upper cross portion, a lower cross portion coupled together to form a rectangular unitary frame structure. The seat back frame also includes an inner wall extending from a front surface and an inner edge of the back frame, and an outer wall extending from the front surface and an outer edge of the back frame, thereby forming a channel on the front surface. A plurality of formations are formed in the back frame to enhance the strength and stiffness of the back frame. The seat back frame also includes a plurality of apertures for attaching other seat components, such as a head restraint assembly. The seat back frame is formed from at least one of a monolithic blank, a tailored welded blank, and/or a tailored welded coil.
Abstract:
A method for forming a tubular structural member includes the steps of cold forming a tube blank to have a longitudinally variable but circumferentially constant wall thickness (t1, t2, t3) and forming the blank into the desired structural member. Preferably, the forming step involves hydroforming.
Abstract:
A metal forming process and welded coil assembly that may be used to form complex metal components in a manner that is efficient, reduces scrap material, and maintains the structural integrity of the components. Generally, a number of individual metal blanks are welded to one or more sheet metal coils in order to produce a welded coil assembly. The metal blanks may be welded along the length of the inner sides of two sheet metal coils, or the metal blanks may be welded along the length of the outer sides of a single sheet metal coil, to cite a couple of possibilities. The welded coil assembly can then be fed through a progressive stamping apparatus or other machine to create a complex metal part.
Abstract:
The invention relates to a method for the manufacture a profile with a cross-section of different thicknesses from a flat metal strip (7) by means of roll-profiling. In this process, a roller pair (2.1, 2.2) produces at least one first recess on at least one side of the metal strip (7), said recess being widened by following roller pairs with incrementally enlarged recess width to form a region with a reduced material thickness (12.1, 12.2). The aim of the invention is to improve the production process, in particular to avoid the formation of undulations during the production of the profile. For this purpose, the invention provides that regions of the flat metal strip (7) which are arranged adjacent to the at least one recess (9.1, 9.2) are bent up before and/or during an engagement of a roller pair (2.1, 2.2).
