摘要： A hot-stamping furnace includes a housing defining a heating chamber partitioned into compartments configured to have different temperatures. The heating chamber includes an opening that is at least partially covered by a door movably mounted on the housing. The door is configured to extend over only a portion of the opening when in a closed position. A detachable panel extends from an edge of the door such that the panel extends over a portion of the opening that the door does not extend over.

摘要： A die apparatus including a first die element, a plurality of second die elements, a plurality of actuators, and a controller is provided. Each of the plurality of actuators is mounted to one of the plurality of second die elements. The controller is programmed to activate the actuators to contact and compress portions of a blank disposed between the die elements at separate pressures to influence microstructure forming for one of a geometry transition region, a deformation region, and a joining region. One of the separate pressures applied to one of the portions of the blank may be approximately 5 N/mm2 or less to form a soft strength zone. The pressure of approximately 5 N/mm2 or less may be applied to the one of the portions of the blank for approximately one to two seconds.

摘要： A method of assembling vehicle-body components includes positioning a first component on a second component. The first component has a different coefficient of thermal expansion than the second component and one of the first and second components defines a slot. The method also includes loosely installing a bolt though the slot and the first and second components, and creating a joint in the first and second components. The method further includes heating the first and second components, which causes the first and second components to move relative to each other due to thermal expansion in response to the heating. This movement causes the joint to fail. The method also includes tightening the bolt.

摘要： Dies for forming components, such as sheet components, and methods of producing the dies are disclosed. The die may include a bulk material and a forming surface. A solid conductor may be formed in the bulk material. The solid conductor may be spaced from and extend adjacent to the forming surface and have a melting point that is greater than a melting point of the bulk material. The solid conductor may be configured to absorb heat from the forming surface. There may multiple solid conductors within the bulk material, for example spaced apart and extending along an axis. The solid conductor may be a bundle of carbon fibers, which may be pitch-based. The solid conductor may be conformal to the forming surface, for example, having a constant spacing therefrom. The solid conductor may be cast-in to the die during its production.

摘要： In at least one embodiment, an assembly is provided comprising a first member including a 6xxx series aluminum alloy heat treated to have a yield strength of at least 200 MPa and an r/t (bendability) ratio of up to 0.4. One or more members may be secured to the first member with a rivet (e.g., a self-piercing rivet). The heat treated alloy may have a yield strength of at least 260 MPa and may have a bendability ratio of up to 0.3. A method of forming an assembly is also provided, including heat treating a 6xxx series aluminum alloy to produce an alloy having a yield strength of at least 200 MPa and an r/t (bendability) ratio of up to 0.4 and riveting a member including the heat treated alloy to one or more additional members.

摘要： A system and method of verifying that a part is heat treated to strengthen the part. The part is marked with a thermo-chromatic composition before heat treating. The part is then heat treated to strengthen the part and change the color of the thermo-chromatic composition to indicate successful completion of the heat treating process. A detector may act to prevent the inclusion of a non-heat treated part in an assembly by disabling an assembly tool. A controller may also provide data related to the completion of the heat treating process to be recorded in a database.

摘要： A method of processing high strength aluminum sheet is provided. The method may comprise uncoiling a coil of O or F-temper 6xxx or 7xxxx series aluminum alloy sheet, tailored rolling the sheet to form a tailored rolled sheet having at least two different thicknesses, blanking the tailored rolled sheet to form a tailored rolled blank (TRB), hot stamping the tailored rolled blank to form a component, and age hardening the component. The tailored rolling operation may reduce the thickness of the aluminum sheet by up to 60% in selected regions. The method may include a hot stamping process for age hardening aluminum alloys that solution heat treats and quenches the TRB. The method may be used to form lightweight, high-strength aluminum vehicle components having a controlled thickness profile to reduce component part weight.
