Claims (3)

  1. Verfahren zum Pressformen eines Stahlrohrs, um eine Stahlplatte in ein Stahlrohr zu formen, wobei das Verfahren umfasst:
    Ausüben eines Druckbiegens, indem die Stahlplatte mehrere Male nach unten gedrückt wird, um ein geschlitztes Nahtrohr (3) zu formen, um es in ein Stahlrohr zu formen; dadurch gekennzeichnet, dass eine Beziehung im Voraus zwischen einem zusätzlichen Betrag eines Herunterdrückens, der ferner erforderlich ist, nachdem eine vorgegebene Nahtlücke während des Ausübens eines Druckbiegens zu einem Endzeitpunkt zu dem geschlitzten Nahtrohr (3) geformt wird, und der vorgegebenen Nahtlücke erhalten wird, und
    das Herunterdrücken bei dem Druckbiegen zu einem Endzeitpunkt auf das geschlitzte Nahtrohr (3) mit dem zusätzlichen Betrag des Herunterdrückens ausgeübt wird, der auf der Grundlage der Beziehung ausgeübt wird, nachdem die vorgegebene Nahtlücke einmal geformt ist.
  2. Verfahren zum Pressformen eines Stahlrohrs nach Anspruch 1, wobei die vorgegebene Nahtlücke eine Nahtlücke zu dem Zeitpunkt ist, zu dem offene Nahtkanten der Stahlplatte in einen Kontakt mit einem Stanzstab (21) eines oberen Stanzstempels (2) gebracht werden.
  3. Verfahren zum Herstellen eines Stahlrohrs, das die folgenden Schritte umfasst:
    Herstellen der offenen Nahtkanten des geschlitzten Nahtrohrs (3), das nach den Ansprüchen 1 oder 2 geformt worden ist, in der Weise, dass die Nahtkanten gegenseitig anstoßen und gegenseitig anliegen; und Zusammenschweißen der offenen Nahtkanten.
