A stock lifter for metal forming dies includes a self-contained assembly. The assembly includes a guide pin that reciprocates within a base. A hardened end cap, which contacts the stock, is attached to the guide pin. A spring is located on the exterior surface of a portion of the base and surrounds the guide pin body. One end of the spring contacts a surface on the cap, while the other end of the spring contacts a surface on the base or an optional mounting flange that is attached above the base. Thus, the stock lifter assembly has a hardened cap for the stock to slide on and a larger, externally mounted spring that provides longer life for the stock lifter. The stock lifter assembly can be made of several different lengths and sizes by using longer or wider guide pins and springs.

A progressive die machine improves forming quality of a low formability material such as an ultra-high strength steel material, or the like, and enhances productivity by adopting rapid heating to a progressive method. The progressive die machine includes: a lower die; an upper die installed to vertically reciprocate with respect to the lower die; a material transfer unit to sequentially transfer a material in a length direction between the upper die and a lower die; a plurality of forming stations installed in the upper die and the lower die; and a rapid heating station installed to be adjacent to at least one of the plurality of forming stations.

The present invention relates to a method of manufacturing formed aluminum components. The method comprises the steps: i. Providing a hollow profile of aluminum or aluminum allow, the profile having a predetermined length and comprising an outer wall having a pre-determined thickness; ii. Placing a hollow aluminum profile in a cavity of a bending tool and press bending the profile using the bending tool; and iii. Transferring the profile to a cavity of a forming tool and subjecting the interior of the profile to elevated gas pressure, whereby the section of the profile is distended until the outer wall of the profile abuts the forming tool, thereby providing a formed aluminum component; wherein the steps ii. and iii. are performed at a tool temperature of 350-470? C. The present invention further relates to formed aluminum components manufactured by such a method.

The present invention provides a hot-stamping formed article which is long and formed of a single steel sheet, the hot-stamping formed article including: two standing wall portions; a top sheet portion adjacent to the two standing wall portions; and a protrusion portion including an overlapping portion in which a portion of the steel sheet extending from at least one standing wall portion of the two standing wall portions and a portion of the steel sheet extending from the top sheet portion overlap, in which an angle between the top sheet portion and the protrusion portion in a case where a plane perpendicular to a longitudinal direction of the hot-stamping formed article is viewed in a cross section is larger than 90.

A pilot assembly and method for metal forming dies has a generally cylindrical pilot with a stripper that strips stock from the pilot when metal forming dies diverge. The pilot assembly is secured to one die member by a fastener by itself or in combination with a window mount. A spring within the pilot assembly contacts the stripper to force the stripper to reciprocate when the dies are pulled apart. Thus, the pilot assembly helps locate the stock within the metal forming die while also having a stripper to help strip the stock from the pilot.

Disclosed is a die having a plurality of divisions through which a source material plate is repeatedly moved and pressed into various types of shims, which are in turn automatically sorted and collected by the types without being mixed.

A method for producing a motor vehicle component from a light metal alloy includes: extruding an extruded profile with, in cross section, at least two mutually different wall thicknesses and at least one closed hollow chamber and with an extrusion width, at least partially flattening and/or widening the cross section to a processing width, wherein the processing width is greater than the extrusion width, before or after the flattening and/or widening, performing separation to form blanks, processing the blanks by deformation to form the motor vehicle component.
