Abstract: A method of evaluating a sheet metal stamping simulation is provided. The method may include defining elements of a finite-element mesh representing a stamped panel, operating on the elements to simulate deformation of the panel during stamping to generate, for each of the elements, incremental differential major and minor plastic strain values, applying a weighting factor to temporally adjacent pairs of the values to generate smoothed values, deriving, from the smoothed values and for each of the elements, a plurality of plastic strain incremental ratios representing plastic flow direction of the elements during the deformation, and altering colors of a map based on the ratios to represent changes in severity of plastic deformation of the stamped panel.

Abstract: A method of forming a part includes extruding a billet through a die, forming a round, closed geometry tube from the billet, and hydroforming the round, closed geometry tube. The extrusion die contains an orifice with a central mandrel, a plurality of bridges, and a corresponding plurality of portholes between the bridges. A spacing of the bridges around the mandrel is non-equiangular. As a result, the round, closed geometry tube has non-equiangular welds after emerging from the die.

Abstract: An apparatus for forming a part is provided, which includes a die. The die includes a round orifice, a central mandrel disposed within the round orifice, and a plurality of bridges and a corresponding plurality of portholes between the bridges. The bridges and the portholes extending around the central mandrel. A spacing of the bridges around the mandrel is non-equiangular. The die allows a material to be extruded through the die to form a round, closed geometry tube from the material such that the round, closed geometry tube has non-equiangular welds after emerging from the die.

Abstract: The present disclosure is generally directed toward a high volume manufacturing method for forming high strength aluminum parts. The method includes acquiring material blanks that are made of 7xxx series aluminum alloy, heating the blanks to a solvus temperature of the material, and stamping and quenching the heated blanks to form multiple parts. The parts are cooled to a second temperature lower than the solvus temperature during the quenching operation. The method further includes performing one or more structural modifications of the parts within a set time period that is less than or equal to 24 hours. The method further includes racking the parts with a gap defined between two adjacent parts, artificially aging the parts with an industrial oven, and pretreating the parts with a chemical solution.

Abstract: Methods of heat treating aluminum alloys are disclosed. The method may include forming a sheet of solution heat-treated, quenched, and aged 6xxx series aluminum having a sheet average yield strength of at least 100 MPa into a component. The component may then be attached to an assembly and at least a portion of the assembly may be painted. The method may then include heat treating the assembly to cure the paint and to increase a component average yield to at least 240 MPa. In another embodiment, the method may include progressively forging a sheet of T4-tempered 6xxx series aluminum into a component using multiple dies and artificially aging the component at 210° C. to 240° C. for 20 to 40 minutes to a component average yield strength of at least 300 MPa. The methods may reduce component cycle time and may reduce strength gradients within the component.

Abstract: A method and a system are disclosed for making an article of manufacture from a blank defining an internal opening. A stack of blanks are aligned and the internal openings of the blanks in the stack of blanks are machined by a rotary cutting tool to a finished dimension. The blanks are clamped together before machining in a numerically controlled machine tool. The blanks are subsequently formed individually in a sheet metal forming operation in which the inner perimeter of the internal openings is expanded as the blank is formed.

Abstract: A method of quenching a press hardenable steel is provided. The method includes an initial step of die quenching a part stamped within a stamping die followed by a partial quenching after the initial step of die quenching. In various methods, the press hardenable steel is a 36MnB5 grade steel and/or the initial step of die quenching is performed at a temperature of approximately 200° C.±10° C. in a die configured for 36MnB5 grade steel. At least one method further includes opening the die followed by the partial quenching, the partial quenching comprising spraying a cooling liquid onto the part to reduce a temperature of the part below approximately 130° C.±10° C., with the option of spraying to reduce the temperature of the part below approximately 100° C.±10° C.
