Abstract

Dargestellt und beschrieben ist ein Verfahren zur Herstellung von großvolumigen Hohlkörpern (10) zumindest teilweise durch hydrostatische Umformung von kaltumformbarem Metall innerhalb einer Formhöhlung eines Gesenks.A method for is shown and described Production of large-volume hollow bodies (10) at least partly through hydrostatic forming of cold formable Metal within a mold cavity Die.

Aufgabe der Erfindung ist es, ein neues Verfahren zur Herstellung von großvolumigen Hohlkörpern zu schaffen, welches bei geringerem Materialeinsatz sowie geringen Kosten eine höhere Prozesssicherheit aufweist.The object of the invention is a new method to create large-volume hollow bodies, which with less use of material and less Has higher process reliability.

Die Lösung dieser Aufgabe ergibt sich insbesondere durch folgende Verfahrensschritte:

  • a. Zuschnitt eines Bleches
  • b. Umformung des Blechzuschnitts (11) sowie Verschweißung der gegenüberliegenden Stoßflächen zur Schaffung eines dreidimensionalen druckdichten Körpers (12) mit mindestens einer Öffnung
  • c. Hydrostatische Aufweitung des Körpers innerhalb eines Gesenks
  • d. Anschweißen eines Verschlussstücks (13).
    • Figure 00000001
    The solution to this problem results in particular from the following process steps:
  • a. Cutting a sheet
  • b. Forming the sheet metal blank (11) and welding the opposite abutting surfaces to create a three-dimensional pressure-tight body (12) with at least one opening
  • c. Hydrostatic expansion of the body within a die
  • d. Welding a closure piece (13).
