Abstract: 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.

Abstract: A hot press processing device 1 includes steps of: a heating step of heating a workpiece W; a press step of press-molding the workpiece W heated in the heating step; a cooling step of cooling a part of the workpiece W press-molded in the press step and causing it to undergo martensite transformation to form a hard zone Zh in the workpiece W, and cooling another part of the workpiece W and causing it to undergo ferrite/bainite transformation to form a soft zone Zs in the workpiece W. In the cooling step, the hot press processing device 1 cools a predetermined portion Zb in the soft zone Zs after increasing rigidity and hardness of the predetermined portion Zb.

Abstract: In certain embodiments described herein, a heated line forming system includes a heating coil system configured to produce a heated line on a surface of a metal part. The heated line forming system also includes an air knife cooling system configured to maintain a dry area for the heated line, and to direct a coolant (e.g., cooling water, liquified gases such as liquid argon, solidified gases such as carbon dioxide snow, and so forth) around the heated line via a spray mechanism such that the coolant does not flow or splash into the heated line on the metal part. In certain embodiments, the heated line forming system includes multiple induction coils arranged along a line and spaced a short distance apart, but which, when operated simultaneously together, form a heated line on a surface of a metal part.

Abstract: An energy-dissipating cover for covering a component sensitive to mechanical impulse includes a sheet of selected ferrous or aluminum alloy, the sheet having a top surface, a bottom surface, an outer perimeter, an overall area within the outer perimeter and a nominal thickness of no more than 2.5 mm. The sheet is configured for connection with one or more external structures at a plurality of connection points within the outer perimeter, wherein the overall area comprises a plurality of supported areas and at least one unsupported area. Embossments are formed within the at least one unsupported area and extend outward from the bottom surface. The embossments are shaped, sized and arranged so as to limit orthogonal deflection of the sheet from a mechanical impulse directed normal to the bottom surface of the sheet at the plurality of embossments.

Abstract: Disclosed herein are systems and method for forming a final hollow body from a metal strip. A forming system may include a forming station, a joining station, an inline heater, and a hydroforming station. Forming the final hollow body from the metal strip may include receiving the metal strip at the forming station and bending the metal strip to a desired cross-section with the forming station and such that longitudinal edges of the metal strip are abutting. In some aspects, the forming station includes at least one roller. The method may include welding the abutting longitudinal edges together as a seam region via the joining station and to form an intermediate hollow body. The method may include heating the seam region of the intermediate hollow body with the inline heater and hydroforming the intermediate hollow body to the final hollow body with the hydroforming station.
