Abstract: The present disclosure relates to forming a metallic part to decrease residual stress and reduce springback behavior in the metallic part after forming. Target locations in the metallic part for excess material are determined based on electronic modelling prior to forming. The excess material in the target locations is configured to decrease residual stress in the metallic part after forming. The metallic part is contacted for forming at one or more contact locations away from as-cut end surfaces of the metallic part, such that the as-cut end surfaces are unconstrained during forming. The excess material is caused, based on the one or more contact locations and the excess material at the one or more target locations, to flow in one or more specific directions during forming to decrease the residual stress in the metallic part and reduce springback behavior in the metallic part after forming.

Abstract: An underbody panel for a motor vehicle is composed of a lightweight sandwich material and is configured as a single part with at least one continuous folding connection (12) that is arranged between first and second portions of the underbody panel (14). The first and second portions can be folded together via the folding connection (12) and, in the folded state, are substantially parallel to each other to reduce a size of the underbody panel during transport and storage. Additionally, the underbody panel is gap-free when installed on a motor vehicle.

Abstract: A blank steel plate is planar and used for producing a press-formed product that has an open cross-section including a bent portion. The blank steel plate is homogeneous in its entirety and includes a belt-shaped thick area that has an increased thickness, thin areas that are adjacent to both sides of the thick area and have a thickness smaller than the thickness of the thick area. On the front surface of a front surface and a back face of the blank steel plate, a step height in thickness is formed along one of both side portions of the thick area, and on the back face, a step height a thickness is formed along the other of both side portions of the thick area. By using the blank steel plate in producing the press-formed product, it is possible to optimizing the strength of the press-formed product, and suppress manufacturing costs.

Abstract: A method of manufacturing a component from a high-strength blank metal strip or sheet (MS) having a tensile strength of at least 850 MPa. The method comprises reducing the thickness (T) of the strip or sheet (MS) in a folding section (FS) so that a shaped section (SS) having a predetermined shape is obtained in at least a part of the folding section (FS). The strip or sheet (MS) is then folded along the shaped section (SS), so that a surface of a first section (1S) becomes arranged adjacent and parallel to a surface a the second section (2S) of the metal strip (MS). Finally, the first and second sections (1S,2S) are joined, so that the strip or sheet (MS) remains folded. With this method, it is possible to use high-strength steel, e.g. AISI 301 stainless steel, and still fold a thin strip or sheet (MS) without undesired cracks in the folding section. For example, the invention is applicable for manufacturing of plate-shaped hair-pulling elements (HPE) for a cutting unit (CU) of a shaving apparatus.

Abstract: A method of forming a closed cross-sectional structure press-forming the plate-shaped workpiece into portions corresponding to bottom portion and left and right side wall portions; and providing bend-facilitating lines at the plurality of bend lines; bending the workpiece in a direction that the portions corresponding to the left and right side wall portions approach each other by pressing a punch into a space between a pair of dies while clamping the portion corresponding to the bottom portion between the punch and a pad in a plate thickness direction; and bending the corresponding portions along the bend-facilitating lines by pressing the corresponding portions against an outer periphery of a plug having an outer peripheral shape the same as a final shape of the closed cross-sectional structure while the plug is placed on the portion of the workpiece corresponding to the bottom portion.

Abstract: A protruding portion is formed in a metal plate material by use of a plurality of molding tools each of which has a die and a punch. In a first step, an initial protruding portion is formed in the metal plate material by use of a first molding tool. In this step, a top of the initial protruding portion is formed to be thinner than other parts. In a second step, a sidewall of the initial protruding portion is rolled out by use of a second molding tool, and the protruding portion is formed.
