摘要： A spacer structure for a sandwich construction, formed from a material web which is provided with a plurality of cuts and which has a material web plane as a first plane, wherein, by forming the material web, at least one support platform is formed in portions which is spaced at a distance from the first plane and is arranged in a second plane. Spacing elements run along a direction of extent (Ε) from the first plane into the second plane in the transition zone from the first plane into the second plane and thus the spacing elements space the first plane apart from the support platform, the spacing elements having a twist about the direction of extent thereof along the direction of extent thereof (Ε), the twist being formed by the shaping of the material web being performed as bending.

摘要： This disclosure relates to methods and apparatuses for production of a workpiece. A first workpiece part is cut free from a first plate-shaped material by a separating cut made via the punch-handling tool. The first workpiece part is held in at least one of a clamped manner and tensioned manner via at least one of an upper tool and a lower tool of a punch-handling tool while being cut free. The workpiece part is aligned with the first plate-shaped material, a further plate-shaped material that differs from a material of the first workpiece part, and a second workpiece part and the aligned pieces are clinching with a clinch tool to connect the pieces at a connection point that is free from a filler material.

摘要： A method for manufacturing a body panel, the method includes drawing a metal sheet into a body panel, trimming a first and second portion of the body panel to form a first and second opening and a cross member. The cross member extends between the first and second openings. The method further includes trimming a portion of the cross member to form a first and a second retention tab and forming a flange in the edge of the first opening, the edge of the second opening and the first and second retention tabs. The method further includes trimming the first and second retention tabs at the edge of the first and second opening.

摘要： When provisionally blanking a lamination sheet by using a punch for provisional blanking and a counter punch, the displacement of pilot holes located around the lamination sheet is minimized. The progressive die machine (1) comprises a pilot hole punch (72), a punch (9) for provisionally punching an iron core laminate (2) from a strip (W) formed with pilot holes (P), a counter punch (31) provided in a lower die assembly (5) and configured to push the iron core laminate (2) against the punch (9), a stripper plate (13) for separating the strip (W) from the provisional blanking punch after a provisional punching, a punch (10) for completely separating the iron core laminate from the strip. At least a part of the stripper plate (13) associated with the provisionally blanking is not in contact with the strip, and at least a part of an outer peripheral part of the provisionally blanked lamination sheet is formed with a connecting portion (79) connected to the strip.

摘要： A bipolar plate having a surface structure for a flow field, inner forms such as holes and slots in the plate, and a reference geometry on the outer form thereof is produced by means of a hydraulic fine-blanking press having an at least three-stage progressive die, in the first stage of which a blank is cut partially free from a metal-foil strip, subsequently in a second stage the surface structure is formed in the connected blank via compression-forming using a forming force of at least 2500 to 3500 kN, the inner form, the slots and the reference geometry are formed by way of cutting in, and on, the blank and then, in a third stage, cutting of the outer contour and removal of the finished blank in the form of the bipolar plate are carried out successively in the stroke cycle.

摘要： A method for producing plate arrangements and using these for cooling gaseous blow-off in electric installation devices, produces a plate stack, which is formed in a cuboidal shape, with a stack length and a stack width. The plate stack is made of shaped rectangular sheets which are produced using a shaping process and are sheet-metal strips of a uniform thickness. First shaped sheets with a uniform length which corresponds to the stack length and second shaped sheets with a width which corresponds maximally to the stack width are used. The shaped sheets are stacked one on top of the other after being shaped such that multiple continuous cavities, i.e., slots, are formed in the longitudinal direction of the stack parallel to the uniform length, and the shaped sheets are connected to one another in a captive mariner so as to form a self-supporting structure of a plate stack.

摘要： A punch includes first and second blade sections juxtaposed relative to each other in a direction parallel or substantially parallel to a feed direction of a sheet material. The first blade section protrudes downwardly from the second blade section with a step intervening therebetween and includes lower end edges on downstream and upstream sides of the feed direction, which define respective punching edges. The first blade section includes a lower end edge following the feed direction, which defines a first notching and punching edge. The notching and punching edge includes a portion intermediate of the feed direction representing a projecting shape. The second blade section includes a lower end edge on the upstream side, which defines a punching edge and also includes a lower end edge following the feed direction, which defines a notching and punching edge. The notching and punching edge is inclined gradually upwardly towards the upstream side.
