Claims (8)

  1. Verfahren zum Bilden eines Gehäuses (5), wobei das Verfahren umfasst:
    einen ersten Schritt des Vorbereitens von Plattenmaterial (1),
    einen zweiten Schritt, in dem eine Dicke eines Umfangsabschnitts (21) des Materials dünner als eine Dicke eines Mittelabschnitts (22) des Materials hergestellt wird, wodurch ein erstes Zwischenprodukt (2) gebildet wird, und
    einen dritten Schritt, in dem das erste Zwischenprodukt (2), das durch den zweiten Schritt erhalten wird, nach vom gezogen wird, um gleichzeitig ein zweites Zwischenprodukt (3) mit der Umfangswand (31) und dem Boden (32) des Gehäuses zu bilden, wobei das zweite Zwischenprodukt (3), das durch den dritten Schritt erhalten wird, nach vorn gezogen wird, um ein drittes Zwischenprodukt (4) mit einem Boden (42) und einer Gehäuseumfangswand (41) zu bilden, dadurch gekennzeichnet, dass das zweite Zwischenprodukt (3) nach vorn/hinten gezogen wird, um an der Innenseite des Bodens (42) einen inneren Vorsprung (43) und optional an der Außenseite des Bodens (42) einen äußeren Vorsprung (44) zu bilden.
  2. Verfahren nach Anspruch 1, wobei der erste Schritt ein Schritt des Schneidens von Blech ist.
  3. Verfahren nach Anspruch 1, wobei der zweite Schritt ein Schritt des gleichzeitigen Stanzens und Formens einer Konkavität im Mittelabschnitt (22) des Materials (1) ist.
  4. Verfahren nach Anspruch 1, wobei der zweite Schritt ein Schritt des Formens durch Schmieden ist.
  5. Verfahren nach Anspruch 1, wobei der zweite Schritt durch Stauchen ausgeführt wird.
  6. Verfahren nach Anspruch 1, wobei dann, wenn a eine Dicke der Umfangswand (31) ist und b eine Dicke des Bodens (32) ist, a < b gilt.
  7. Verfahren nach Anspruch 1, wobei ein Zwischenprodukt, das durch den dritten Schritt erhalten wird, nach vom gezogen wird, um gleichzeitig die Gehäuseumfangswand (41) und den inneren Vorsprung (43) zu bilden.
  8. Verfahren nach Anspruch 1, wobei ein erstes Zwischenprodukt (2), das durch den zweiten Schritt erhalten wird, geglüht wird, bevor es einem nachfolgenden Schritt unterworfen wird.
