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.

The disclosure relates to a method for producing a overlapping connection, in which at least two overlapping components are connected to one another via a folded flange, with a first edge of a first component being folded over a second edge of a second component to form the folded flange, along with a body component that includes such an overlapping connection for a vehicle and a stamping tool for such a body component. According to the disclosure at least one connection region is formed on the folded flange, in which the stamping tool stamps the first component through the second component at least one stamping point, with displaced material of the first component passing into the second component and producing a positive connection.

A metal plate stamping method is provided for cutting a metal plate, on which a bulging portion is formed through stamping, at a cutting area that is defined in a portion other than the bulging portion. The method includes forming a bead on the opposite side of the cutting area from the bulging portion and crushing the bead prior to the cutting of the metal plate.

A container system and a method for forming a knob in a container. The container system includes a container, in particular a medical or surgical sterile container preferably having a tub-like container vessel and/or a container cover; at least one separate coupling element; and at least one coupling system for releasably connecting the coupling element to the container. The coupling system includes a male coupling portion formed on the container and a female coupling portion formed on the coupling element. The coupling portions can be coupled to and uncoupled from one another. The male coupling portion is integrally formed in a wall of the container and is designed as a protruding knob having an undercut.

Disclosed is a battery cell with improved weldability and an apparatus for processing the same, and more particularly to a battery cell including an electrode assembly received in a cell case; and a pair of electrode leads constituted by a negative electrode lead and a positive electrode lead protruding outwards from the cell case, wherein: the negative electrode lead is made of a nickel material and is provided with one or more embossed portions, and the positive electrode lead is made of an aluminum material and is provided with no embossed portion.

The disclosure relates to a method for producing a overlapping connection, in which at least two overlapping components are connected to one another via a folded flange, with a first edge of a first component being folded over a second edge of a second component to form the folded flange, along with a body component that includes such an overlapping connection for a vehicle and a stamping tool for such a body component. According to the disclosure at least one connection region is formed on the folded flange, in which the stamping tool stamps the first component through the second component at least one stamping point, with displaced material of the first component passing into the second component and producing a positive connection.

A method for preparing a modular planar interconnect plate includes steps of a) providing a metal blank sheet having a main region and two first lateral regions, b) forming two openings respectively in the first lateral regions, and c) stamping to form protrusions and depressions at the main region on lower and upper surfaces of the metal blank sheet. In the stamping step, each of two lower surrounding protrusions and two upper surrounding depressions is formed to surround a corresponding one of the openings, and each of an upper surrounding protrusion and a lower surrounding depression is formed to surround the corresponding ones of the protrusions and depressions formed at the main region and the first lateral regions.

According to an embodiment, a mold structure comprises an upper mold having a convex portion in a lower surface thereof to press-form a thin aluminum sheet, a lower mold including a main mold part having a forming recess for forming the thin aluminum sheet placed thereon and an auxiliary mold part supporting the main mold part, a back plate spaced apart from an inside of the forming recess and supporting a lower surface of the aluminum sheet, and vacuum generator connected with air passages formed from two opposite sides of the auxiliary mold part to a bottom surface of the forming recess.
