Definitions

  • the invention relates to a method for forming workpieces from a strip of material using a Ausformtosstoffes by means of a tool which at least partially or completely penetrates along a contour in the strip of material.
  • workpieces are punched out of sheet metal from corresponding metal strips or cut in a fine blanking process.
  • a corresponding fine blanking method is, for example, in the GB-A 1 224 543 described.
  • the fine blanking tool used here ensures during the punching movement that a lubricating film is present between the die of the fine blanking tool and the sheet material to be punched, for which normal lubricant is used.
  • the invention relates to separation and forming processes such as shearing and fine blanking but also to other methods of forming and forming workpieces, for example.
  • the bending, drawing, extrusion, stretching, expressing, deep drawing, notching, cutting, half-cutting, etc. .. refers to all methods in which for Aus- and forming the workpieces a Ausformangesstoff, z.
  • Object of the present invention is to make the application of Ausformysschers on the material strip substantially consumption-optimized and functionally efficient.
  • the tool could be associated with a corresponding device which applies the lubricant when lowering the tool on the strip of material on the latter by spraying or spraying.
  • a corresponding device which applies the lubricant when lowering the tool on the strip of material on the latter by spraying or spraying.
  • fine nozzles which are similar to the ink jet printer or a single or multi-row spray bar with juxtaposed nozzles are provided which record the Stanfordformende workpiece contour with a certain line thickness.
  • the amount and duration of these nozzles are then freely programmable, and the points can be kept larger or smaller.
  • the Ausformysstoff is applied before the molding process itself on the strip of material. Again, this can be done by spraying or spraying or even drops. But it can also be done by rolling or printing. In this way, the lubricant can be relatively accurately limited to the contour of the Schwarzformenden workpiece, so that a very effective volume and consumption-optimized and thus cost-saving application process is offered.
  • a structured surface is present on the cylindrical surface of the punch of a punching or fine blanking tool, in which the Ausformangesstoff can store for the purpose of depot formation.
  • the cylinder can therefore have on the surface of a pore-shaped structure or an "orange peel".
  • the necessary lubricant or additive cocktail can be applied in all possible forms and states to the material strip, for example also as a paste or as a solid lubricant.
  • the lubricant is added.

    caractérisé par le fait
    que le lubrifiant n'est appliqué sous forme de matière auxiliaire de façonnage que le long du contour des pièces à façonner, avant ou pendant le façonnage des pièces, d'un ou des deux côtés sur la bande de matériau.
  2. Procédé selon la revendication 1, caractérisé par le fait que la matière auxiliaire de façonnage est appliquée des deux côtés le long du contour sur la bande de matériau.
  3. Procédé selon l'une des revendications 1 ou 2, caractérisé par le fait que la matière auxiliaire de façonnage est appliquée depuis l'outil directement sur la bande de matériau le long du contour.
  4. Procédé selon l'une des revendications 1 à 3, caractérisé par le fait qu'une partie de l'outil, par exemple un poinçon, présente une structure de surface dans laquelle est reçue au moins une partie de la matière auxiliaire de façonnage.
