摘要： A forming die includes a first die component with a male bead and a second die component with a female bead. The male bead and the female bead form a bead with a reverse bead geometry with the male bead having a groove and the female bead having a protrusion complimentary with the groove such that the protrusion is aligned with the groove when the male bead extends into the female bead. The male bead includes a push surface, a pair of sidewalls extending from the push surface to a main surface of the first die component, and the groove extends inwardly into the rib. And the female bead includes a stop surface and a pair of sidewalls extending from the stop surface to a main surface of the second die component, and the protrusion extends outwardly from the stop surface into the female bead.

摘要： A method of forming a stamped part includes forming a tailor welded blank by friction stir welding (FSW) a first blank to a second blank, removing a FSW start spot and a FSW stop spot from the tailor welded blank using a machining process such that a finished tailor welded blank is formed and stamping the finished tailor welded blank into the stamped part such that a weld formed by FSW the first blank to the second blank is plastically deformed. The first blank and the second blank can be aluminum alloy blanks and a predetermined amount of material is machined from the FSW start spot and the FSW stop spot, the predetermined amount of material being equal to or greater than a thickness of the first blank and the second blank.

摘要： A reinforcement received between facing surfaces of adjacent panels that may be part of a hinge pillar of a vehicle such as a pickup truck and the panels may be aluminum. The reinforcement may be a one-piece molded structure. The reinforcement includes ribs that extend between the facing surfaces in a lattice arrangement defining a plurality of cells. The cells may have a number of transverse walls defining a perimeter of a polygon. The polygonal cells may have a facing wall on one side of the cell closing the cell. The facing wall may have an adhesive that is applied to the reinforcement and expanded in a paint bake oven to secure the reinforcement to the adjacent panels.

摘要： A method of hydroforming a vehicle rail from an extruded aluminum tube includes the steps of positioning the extruded aluminum tube into a hydroforming die and partially closing the hydroforming die. Next is the step of applying a liquid under a first level of pressure to the extruded aluminum tube in the hydroforming die. This is followed by engaging an inner radius of a bend in the extruded aluminum tube with the hydroforming die before completely closing the hydroforming die and increasing the level of liquid pressure in the workpiece to a second level to form and hydro-pierce a part from the extruded aluminum tube.

摘要： A self-piercing rivet (SPR) includes a head portion and a shaft extending from the head portion. The shaft defines a hollow bore and a sidewall surrounding the hollow bore. The sidewall has a reduced thickness towards a distal end portion of the shaft to define a cutting edge on a distal end tip of the shaft, and the SPR defines a circumferential groove disposed at least partially around the shaft and extending into the sidewall.

摘要： A value stream process or method for forming vehicle rails from extruded aluminum tubes includes the steps of extruding an aluminum tube and hydroforming the extruded aluminum tube into a vehicle rail. More specifically, the method includes extruding the aluminum tube, bending the aluminum tube, preforming the aluminum tube, hydroforming the aluminum tube into a vehicle rail, trimming the vehicle rail to length and then artificially aging the rail followed by batch chemical pretreatment. In an alternative embodiment the artificial aging and batch chemical pretreatment processes are performed in reverse order. In either of the embodiments, localized induction annealing to recover formability may be performed between bending and preforming, between preforming and hydroforming or both.
