    摘要： The invention relates to a method for embossing and cutting into workpieces (4), having the following method steps: - providing a flat workpiece (4), - inserting the flat workpiece (4) between a stamp (2) and a cutting die (5), said stamp (2) having a notch (3) which lies opposite a cutting edge (6), and - pressing the workpiece (4) between the stamp (2) and the cutting die (5), wherein the cutting edge (6) cuts into the workpiece (4), and the material from which the workpiece (4) is made is drawn. The aim of the invention is to provide a method and an embossing tool for embossing and cutting into workpieces, in particular workpieces made of steel sheets, such that a warping in the workpiece can be minimized using said method and embossing tool, said method and embossing tool being characterized in that the material of the workpiece (4) is slowed at least in some regions during the cutting and drawing process and the flow of the material is controlled. This is achieved by an embossing tool (1) for carrying out a method of the aforementioned type, comprising a stamp (2) in which a notch (3) for receiving a material of a workpiece (4) is formed and comprising a cutting die (5) which lies opposite the stamp (2) and which has a cutting edge (6) that can cut into the material of the workpiece (4) such that the material is forced into the notch (3) lying opposite the cutting edge (6), said stamp (2) and cutting die (5) being movable relative to each other, wherein slowing means (7) are provided which retain the material at least in some regions.

    摘要： Provided are a method for splitting longitudinally an end part of a metal plate or a metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed; a metal part manufactured by such method; and a method for bonding such metal part. The present invention is characterized by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

    摘要： Die Erfindung betrifft ein Rohr (1) mit einem verjüngten Rohrende. Derartige Rohre können ineinandergesteckt werden und finden insbesondere im Gerüstbau Anwendung. Erfindungsgemäß ist vorgesehen, dass der verjüngte Abschnitt mit dem Rest des Rohrs (1) einstückig über einen Doppelfalz (30) verbunden ist, wobei die Falzlagen (2,3,4) des Doppelfalzes (30) unmittelbar aneinander anliegen. Die Erfindung stellt ferner ein Verfahren zur Herstellung eines derartigen Rohrs (1) bereit. Dazu wird zunächst das Rohrende eines Rohrs (1) mit konstantem Durchmesser in einer Formhülse eingezogen. Zwischen dem verjüngten Abschnitt (20) und dem unverformten Teil des Rohrs (10) wird in einem nächsten Verfahrensschritt durch Stauchen des Rohrs (1) ein umlaufender nach außen abstehender Wulst (6) erzeugt. Anschließend wird der Wulst (6) in Richtung des freien Endes des Rohrs (1) umgeschlagen, sodass ein Doppelfalz (30) entsteht, dessen Falzlagen (2,3,4) unmittelbar aneinander anliegen.

    摘要： A method of producing support pillars for use in the fabrication of evacuated glass panels and, in particular, for use in the fabrication of evacuated glazing. The method comprises the steps of: (a) forming in opposite surfaces (15, 16) of a metal blank (10) periodically spaced pairs of aligned linearly extending indentations (13, 14 and 17, 18) and, as a consequence, creating regions of weakness (23) that extend between troughs (24) of the respective pairs of indentations, and (b) parting individual support pillars (28) from the metal blank (in which the indentations are formed) at the respective regions (23) of weakness.
