Definitions

  • the invention relates to a method for manufacturing braided metal structures and such a structure. It is therefore related to the technical sector of metal braiding and, in particular, braided metal products. These products may be, for example, plates, trays, panels, chairs, furniture.
  • FIGS. 1 and 2 show the implementation of the configuration of a braided grid. Beams of the metal strips (A - B) are alternately arranged, over and under, in perpendicular planes thereby providing an alternative overlap of the transverse strips with respect to the longitudinal strips.
  • the implementation of this method allows to obtain various forms of cutting and braiding, in visual aspects of different axial planes and in the context of a continuous manufacturing automation.
  • a braided metal structure according to the invention is defined in claim 2.
  • Claims 3 to 5 relate to uses of the structure of the invention.
  • FIG. 6 shows an example of a plate (10) to be worked by the method according to the invention.
  • This sheet metal plate is solid in dimensional characteristics established from manufacturing production considerations and mesh to achieve.
  • the plate is arranged with the formation of a plurality of holes (10a) according to a pre-established grid, these holes being of square, rectangular or other configuration, obtained using appropriate punches. whose profiles are complementary. The positioning of the holes and their shape are chosen according to the final appearance to be obtained from the braided plate.
  • the next step is to define strips to be shaped, from the dimensions, width and length of the plate to be worked and to proceed to the successive operations of stamping half-flesh, on the one hand for all bundles strips (C) located along the same longitudinal axis, and step by step with the desired offset.
  • the width of the bands worked, and thus shaped, depends on the shape of the mesh.
  • Mid-body stamping operations are done using a numerically controlled machine capable of performing the aforementioned operations.
  • the operation After executing a first line in a longitudinal plane, the operation continues with an axial offset, parallel to the first line (L1 - L2 ... LN), to form the entire useful surface of the plate in the longitudinal direction. Then the forming tools are rotated at 90 ° to make, by pressing halfway, complementary operations in the oblique direction, for example, transverse, line by line (La, Lb, Ln), to obtain a braiding complete along the axes (XX - YY) of the worked metal plate.
  • the numerically controlled machine executes the successive operations in a very short time after programming.
  • the braided metal plate according to the method of the invention, remains monoblock without interstice since there is no longer crossing zone and overlap bands.
  • the visual aspect of the finished product gives the braided appearance. Referring to Figure 3, each of the faces of the braided plate has a mid-flesh stamping appearance.
  • the method, object of the invention finds multiple applications and, by way of example, not limited to, those cited relating to braided metal structures for furnishing, making furniture, displays, panels, and a way for any product having a substantially flat face to form support planes or sitting or decoration.
  • the resulting product can remain flat or be shaped by bending or otherwise. Depending on the applications, it can be framed.

  1. Verfahren zum Herstellen von metallischen geflechteten Strukturen, bei dem die folgenden Arbeitsgänge durchgeführt werden:
    - ausgehend von einer massiven Metallplatte (10) Bildung einer Vielzahl von Löchern (10a) in einer voreingestellten und gespeicherten Position, wobei die Löcher (10a) eine festgelegte Konfiguration besitzen und mit Hilfe eines geeigneten Stanzwerkzeuges hergestellt sind,
    - Durchführung eines oberflächigen Tiefzieh-Arbeitsganges über die Hälfte der Dicke der Platte (10), Stoß für Stoß, entsprechend einer voreingestellten Maschenweite zwischen zwei aufeinanderfolgenden Löchern und entsprechend des massiven Teils der Platte (10), wobei dieser Tiefzieh-Arbeitsgang in einer Längsrichtung der Platte (10) entlang einem festgelegten Band erfolgt,
    - Durchführung sämtlicher Tiefzieh-Arbeitsgänge durch Verschiebung in den Längsebenen der Platte (10), um die Bündel der Längsbänder (C) zu begrenzen,
    - die folgende Phase besteht darin, das Werkzeug in Abhängigkeit von den herzustellenden Formen in einer axialen Ebene zur Längsrichtung der Platte (10) anders auszurichten, und einen zweiten oberflächigen Teil-Tiefzieh-Arbeitsgang in einer anderen Ebene als der ersten Formgebungslinie durchzuführen und eine Vielzahl von Bändern in derselben Ebene zu formen bzw. herzustellen, bis die Gesamtheit der Nutzfläche der Platte (10) und die entsprechende Verflechtung gebildet ist.
  2. Mittels des Verfahrens nach Anspruch 1 hergestellte metallische geflechtete Struktur, die aus einem Stück und ohne Zwischenräume in einer Längsebene eine Vielzahl von Bändern (C) und in axialer Richtung zu der Längsebene mit den Querlinien (La, Lb, Ln) eine Vielzahl von Bändern besitzt, wobei die Bänder allesamt über die Hälfte der Dicke der Platte (10) oberflächig gebildet sind, so dass ein vollständiges Geflecht erhalten wird.
  3. Verwendung einer metallischen geflechteten Struktur nach Anspruch 2 gekennzeichnet durch Einrichtungsgegenstände.
  4. Verwendung einer metallischen geflechteten Struktur nach Anspruch 2 gekennzeichnet für die Herstellung von Paneelen.
  5. Verwendung einer metallischen geflechteten Struktur nach Anspruch 2 für die Herstellung von Dekorationsartikeln.
