VERFAHREN ZUM HERSTELLEN VON BLECHTAFELN AUS METALLBANDMETHOD OF MANUFACTURING TIN PANELS FROM METAL STRIP

Die Erfindung betrifft ein Verfahren zum Herstellen von Blechtafeln atis Metallband, das einem Streckrichtprozeß unterworfen wurde. Unter dem Streckrichten versteht man die Erzeugung hoher Zugspannungen im Band, verbunden mit einer Richtungsänderung durch Biegen, wodurch das Band plastisch verformt wird, um innere Spannungen weitgehend zum Verschwinden zu bringen. Das Streckrichten wird insbesondere dann angewandt, wenn an die Planheit von Bandmaterial aus Metall hohe Anforderungen gestellt werden.The invention relates to a method for producing metal sheets atis metal strip that is subjected to a stretch-straightening process became. Stretch straightening is the generation of high tensile stresses in the strip, combined with a change in direction by bending, as a result of which the band is plastically deformed in order to bring internal stresses to a large extent to disappear. The stretch straightening is used in particular when high demands are placed on the flatness of strip material made of metal.

Wegen des erforderlichen Vorzuges vor der Streckrichtanlage hat man bisher das Metallband wieder zu einem Bund aufgewickelt, um es dann in einer Scherenlinie zu Blechtafeln zu unterteilen. Es wurde erkannt, daß durch das erneute Aufwicklen des Metallbandes um einen Haspeldorn erneut Biegespannungen und Aufwölbungen im Material entstehen, die die Planheit nachteilig beeinflussen. Die Aufwölbungen kennzeichnen sich dadurch, daß die Randbereiche des Metalibandes beim erneuten Aufwickeln die Tendenz haben, sich vom Haspeldorn weg aufzuspreizen. Diese Erscheinung beruht vermutlich darauf, daß beim Aufwickeln die innere Faser des Bandes gedrückt und die äußere gezogen wird, was sich aber nur im mittleren Bereich des Bandes in einer über die Dicke des Bandes umkehrenden Spannungsverteilung von Druckspannung nach Zugspannung auswirkt, wogegen in den Randbereichen sich die unterschiedliche Spannungsverteilung in einer Formänderung frei auswirken kann, was dann nur zu einem Abheben der Randbereiche führen kann. Diese /Aufwölbungen sind im elastischen Bereich und verschwinden durch dasBecause of the necessary preference in front of the stretch straightening system, the metal strip has so far been wound up again to form a bundle then to subdivide it into sheet metal in a scissor line. It was recognized that by rewinding the metal tape Bending stresses and bulges in the material arise again around a reel mandrel, which adversely affect the flatness. the Bulges are characterized by the fact that the edge areas of the metal tape have a tendency to pull away when rewound Spread the reel mandrel open. This phenomenon is presumably based make sure that the inner fiber of the tape is pressed and the outer fiber is pulled when winding, but this is only in the middle area of the belt has the effect of a stress distribution that is reversed over the thickness of the belt from compressive stress to tensile stress, whereas in the edge areas the different stress distribution can freely affect a change in shape, what then can only lead to a lifting of the edge areas. These / bulges are in the elastic range and disappear due to the

Aufwickeln unter Zug, jedoch federn sie zurück, wenn das Metallband zum Unterteilen wieder abgewickelt wird.Winding up under tension, however, they spring back when the metal band is unwound again for subdividing.

Der Erfindung liegt die Aufgabe zugrunde, Blechtafeln mit einem Höchstmaß von Planheit herzustellen. Dies wird gemäß der Erfindung verfahrensmäßig dadurch erreicht, daß das Metallband unmittelbar nach dem Streckrichten im fliegenden Schnitt unterteilt wird. Eine Anlage zur Durchführung des Verfahrens kennzeichnet sich somit durch eine einer Streckrichtanlage nachgeordnete, mit dieser synchronisierten Querteilschere. Die Querteilschere kann sowohl eine Schwingschere als auch eine Trommelschere sein.The invention is based on the object of producing metal sheets with a maximum degree of flatness. This is done according to the invention In terms of the method, this is achieved in that the metal strip is subdivided in a flying cut immediately after stretch straightening will. A system for carrying out the process is thus characterized by a stretch straightening system, with this synchronized cut-to-length shear. The cut-to-length shear can be rocking shears as well as drum shears.

Da der Zug durch den Aufwickelhaspel bei einer Anlage gemäß der Erfindung fortfällt, kann es erforderlich sein, zwischen der Streckrichtanlage und der Querteilschere eine zugerzeugende Vorrichtung anzuordnen, zum Beispiel ein Treibrollenpaar oder einen Doppeltreiber.Since the train by the take-up reel is omitted in a system according to the invention, it may be necessary between the Stretch straightening system and the cut-to-length shear to arrange a feeding device, for example a pair of driving rollers or one Double driver.

In der Zeichnung ist schematisch eine Anlage gemäß der Erfindung zur Herstellung von Blechtafeln größter Planheit aus Metallband dargestellt. Man erkennt eine übliche Streckrichtanlage mit zwei S-Rollengerüsten 2 und 4, zwischen denen sich die Biegeeinheit 5 mit den Biegerollen 6 befindet. Das Metallband 1 läuft in Pfeilrichtung ein.The drawing shows a system according to the invention for the production of metal sheets of the greatest flatness from metal strip shown. A conventional stretch-straightening system can be seen with two S-roll stands 2 and 4, between which the bending unit 5 is located with the bending rollers 6 is located. The metal strip 1 runs in in the direction of the arrow.

Der Streckrichtanlage nachgeordnet ist eine Schwingschere 7, die mit dem Antrieb für die S-Rollen 2 und 4 synchronisiert ist. Die Streckrichtanlage dient demgemäß für die Schwingschere 7 ebenso als Schrittmacher, wie in einer vom Bund arbeitenden Querteilanlage die der Querteilschere vorgeordnete Rollenrichtmaschine.Downstream of the stretch straightening system is an oscillating shear 7, which is synchronized with the drive for the S-rollers 2 and 4. the The stretch-straightening system accordingly serves as a pacemaker for the rocking shears 7 as well as in a cut-to-length system working from the federal government the roll straightener upstream of the cut-to-length shear.

Um den durch den Wegfall des Aufwickelhaspels fehlenden Bandzug an der Auslaufseite der Streckrichtanlage zu ersetzen, ist zwischen der Schwingschere 7 und dem auslaufseitigen S-Rol.lengerüst 4 ein Treibrollenpaar 8 vorgesehen.In order to replace the missing tape tension on the outlet side of the straightening system due to the omission of the take-up reel between the rocking scissors 7 and the outlet-side S-Rol.lengerüst 4 a pair of driving rollers 8 is provided.
