  9. Biegeanlage (9) gemäß Anspruch 8, wobei die Formgebungsvorrichtung (22) umfasst:
    - einen Rahmen (23), der parallel zur Vorschubrichtung zwischen einer hinteren Position und einer vorderen Position beweglich montiert ist, wobei der Rahmen (23) mit einem vierten Stellglied (24) verbunden ist, welches den Rahmen (23) zwischen der hinteren Position und der vorderen Position bewegen kann; und
    - einen Stempel (25), der vertikal beweglich auf dem Rahmen (23) der Formgebungsvorrichtung (22) zwischen einer Ruheposition und einer Formgebungsposition montiert ist, wobei der Stempel das Metallblech (1) verformt, um die Form einer Querwelle zu ändern, die zuvor durch die Biegevorrichtung (12) gebildet wurde, wobei der Stempel (25) mit einem fünften Stellglied (26) verbunden ist, welches dazu geeignet ist, den Stempel (25) zwischen der Ruheposition und der Formgebungsposition zu bewegen.
  10. Biegeanlage (9) gemäß Anspruch 9, wobei die Steuereinheit (29) so konfiguriert ist, dass sie das vierte Stellglied (24) und das fünfte Stellglied (26) steuert.
  11. Biegeanlage (9) gemäß Anspruch 10, wobei die Steuereinheit (29) so konfiguriert ist, dass sie die Antriebsvorrichtung (11) so steuert, dass das Metallblech (1) mit einer Geschwindigkeit V1 von hinten nach vorne vorgeschoben wird, und wobei die Steuereinheit (29) so konfiguriert ist, dass das vierte Stellglied (24) den Rahmen (23) der Formgebungsvorrichtung (22) aus der hinteren Position in die vordere Position mit einer Geschwindigkeit V3 bewegt, die bei der Bewegung des Stempels (16) der Biegevorrichtung (12) aus der Ruheposition in eine Zwischenposition, in der der Stempel (16) der Biegevorrichtung das Metallblech (1) berührt, gleich V1 ist und bei der Bewegung des Stempels (16) der Biegevorrichtung (12) aus der Zwischenposition in die Biegeposition gleich null ist.
  12. Verfahren zum Betreiben einer Biegeanlage (9) gemäß einem der Ansprüche 1 bis 11, wobei das Verfahren umfasst:
    - Positionieren eines Metallblechs (1), so dass die Antriebsvorrichtung (11) für einen Vorschub des Metallblechs (1) sorgt; und
    - Ansteuern des ersten Stellglieds (14) und des zweiten Stellglieds (17) mittels der Steuereinheit (29), um gleichzeitig den Rahmen (13) der Biegevorrichtung (12) aus der hinteren Position in die vordere Position und den Stempel (16) aus der Ruheposition in die Biegeposition zu bewegen.
  13. Verfahren gemäß Anspruch 12, bei dem das zweite Stellglied so gesteuert wird, dass:
    - das zweite Stellglied (17) den Stempel (16) in Richtung der Biegeposition mit einer Geschwindigkeit V7 zwischen 0,95 V 1 2 × 1 sin ∝ − 1 tan ∝ |
    Figure imgb0034
     und 1,05 V 1 2 × 1 sin ∝ − 1 tan ∝ |
    Figure imgb0035
    , bewegt; mit
    α: der Winkel zwischen einer der Seiten des Querschnitts des Stempels (17) und einer horizontalen Achse.
  14. Verfahren gemäß Anspruch 12 oder 13, bei dem das erste Stellglied (14) so gesteuert wird, dass es den Rahmen (13) der Biegevorrichtung (12) von der hinteren Position in die vordere Position mit einer Geschwindigkeit, die zwischen 0,95 × 1 2 V 1
    Figure imgb0036
     und 1,05
    Figure imgb0037
     × 1 2 V 1
    Figure imgb0038
     liegt bei der Bewegung des Stempels (16) von einer Zwischenposition, in der der Stempel (16) der Biegevorrichtung (12) das Metallblech (1) berührt, in die Biegeposition, bewegt.
  15. Verfahren gemäß einem der Ansprüche 12 bis 14, wobei das erste Stellglied (14) und das zweite Stellglied (17) so angesteuert werden, dass der Rahmen (13) bei der Bewegung des Stempels (16) aus der Biegeposition in die Ruheposition weiter in die Vorwärtsposition bewegt wird.
  16. Verfahren gemäß einem der Ansprüche 12 bis 15, wobei die Biegeanlage (9) weiterhin stromabwärts der Biegevorrichtung (12) eine Formgebungsvorrichtung (22) umfasst, die zum Modifizieren einer zuvor mittels der Biegevorrichtung (12) gefalteten Welle konfiguriert ist, wobei die Formgebungsvorrichtung (22) umfasst:
    - einen Rahmen (23), welcher parallel zur Vorschubrichtung zwischen einer hinteren Position und einer vorderen Position beweglich angebracht ist, wobei der Rahmen (23) mit einem vierten Stellglied (24) verbunden ist, welches dazu geeignet ist, den Rahmen (23) zwischen der hinteren Position und der vorderen Position zu bewegen; und
    - einen Stempel (25), welcher vertikal beweglich an dem Rahmen (23) der Formgebungsvorrichtung (22) zwischen einer Ruheposition und einer Biegeposition angebracht ist, wobei der Stempel (25) das Metallblech (1) verformt, um die Form einer Querwelle zu ändern, die zuvor durch die Biegevorrichtung (12) gebildet wurde, wobei der Stempel (25) mit einem fünften Stellglied (26) verbunden ist, welches den Stempel zwischen der Ruheposition und der Biegeposition bewegen kann,
    und wobei das vierte Stellglied (24) so gesteuert wird, dass es den Rahmen (23) der Formgebungsvorrichtung (22) aus der hinteren Position in die vordere Position mit einer Geschwindigkeit V3 bewegt, die gleich V1 ist, wenn der Stempel (16) der Biegevorrichtung (12) aus der Ruheposition in eine Zwischenposition, in welcher der Stempel (16) der Biegevorrichtung (12) das Metallblech (1) berührt, bewegt wird und die gleich null ist, wenn der Stempels (16) der Biegevorrichtung (12) von einer Zwischenposition, in der der Stempel (16) der Biegevorrichtung (12) das Metallblech (1) berührt, in die Biegeposition bewegt wird.
