Abstract

Working flexible band material (13) rolled onto coils (12), comprises unwinding the material in a winding unit (11) and cutting individual sections (16) to size. The individual boards are rotated about 90 [deg] in the band material plane. The boards are then moved forward and worked.

Description

Beim sogenannten flexiblen Walzen wird Bandmaterial mit sich periodisch ändernder, definiert unterschiedlicher Materialdicke hergestellt. Eine Periodenlänge des gewalzten Längsdickenprofils entspricht im wesentlichen der Länge eines aus dem Bandmaterial herzustellenden Einzelbauteils und in seiner Materialdicke dem späteren Belastungsprofil dieses Bauteils. Der Walzprozeß ist also so ausgelegt, daß im aufgewickelten Coil nach dem Walzen das Material für Einzelplatinen kontinuierlich aneinander anschließt, d. h. beim Walzen werden in Bandlängsrichtung Blechdikkenprofile erzeugt, die sich als kontinuierlich aneinandergereihte Platinen im Band darstellen. Nach dem Walzprozeß wird das Band zunächst zum Coil aufgewickelt. Der Coil wird in der Regel wärmebehandelt, wobei anschließend eine Oberflächenbehandlung stattfinden kann, die am abgewickelten Band durchgeführt wird. Danach wird das Bandmaterial wieder zum Coil aufgewickelt. Zur weiteren Bearbeitung, d. h. zur Abtrennung von Platinen und zur Weiterbearbeitung zu Blechumformteilen in Pressen, wird idealerweise das Bandmaterial in einem Bearbeitungszug vom Coil abgewickelt, zu Einzelplatinen abgetrennt und den Pressen zugeführt, um ein fertig geschnittenes und gezogenes bzw. gepreßtes Blechumformteil mit unterschiedlichen Wandstärken herzustellen.In so-called flexible rolling, strip material is changed periodically, defined different material thickness produced. A period length of the rolled Longitudinal profile corresponds substantially to the length of one of the Band material to be produced individual component and in its material thickness later Loading profile of this component. The rolling process is thus designed so that in After rolling, coil continuously wound the material for single boards connected to each other, d. H. When rolling are in the strip longitudinal direction Blechdikkenprofile produced, which are as continuously juxtaposed boards in the tape represent. After the rolling process, the tape is first wound into a coil. The coil is usually heat treated, followed by a surface treatment take place, which is performed on the unwound tape. After that The tape material is wound up again to the coil. For further processing, d. H. for the separation of blanks and for further processing to sheet metal forming parts in Pressing, ideally, the strip material is in a processing run from the coil unwound, separated into individual boards and fed to the presses to finish one cut and drawn or pressed Blechumformteil with different To produce wall thicknesses.

Aus produktionstechnischen Gründen beim flexiblen Walzen und/oder aus dem Anforderungsprofil der fertigen Blechumformteile ergibt es sich, daß die abgetrennten Einzelplatinen in der Regel größere Länge L als Breite B in Walz- bzw. Abwickelrichtung haben. Hiermit ergeben sich beim Weitertransport in Pressen, Transferwerkzeugen oder Transferstraßen ungünstige Verhältnisse hinsichtlich der Werkzeuganordnung und des von den Werkzeugen innerhalb einer Transferstraße benötigten Bauraums.For reasons of production technology during flexible rolling and / or from the requirement profile the finished Blechumformteile it turns out that the separated Single boards usually greater length L than width B in the rolling or unwinding to have. This results in further transport in presses, transfer tools or transfer lines unfavorable conditions with respect to the tool arrangement and that needed by the tools within a transfer line Installation space.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Verfahren zur Verarbeitung von auf Coils aufgewickeltem flexiblen Bandmaterial vorzuschlagen und entsprechende Vorrichtungen bereitzustellen.On this basis, the invention is based on the object, an improved method to propose for the processing of flexible strip material wound on coils and to provide corresponding devices.

Eine erste Lösung hierfür besteht in einem Verfahren zur Verarbeitung von auf Coils aufgewickeltem flexibel gewalzten Bandmaterial mit sich periodisch ändernder Materialdicke in Einzelpressen, Transferwerkzeugen oder Transferstraße zu einzelnen Blechumformteilen mit der Abfolge der Bearbeitungschritte:

  • 1. Abwickeln des flexibel gewalzten Bandmaterials in einer Haspelvorrichtung vom Coil,
  • 2. Ablängen einzelner untereinander gleicher Platinen mit größerer Länge L als Breite B quer zur Abwickelrichtung A des Bandes,
  • 3. Verdrehen der einzelnen Platinen um 90° in der Bandmaterialebene,
  • 4. schrittweises Vorschieben und Bearbeiten der einzelnen Platinen in einer mit der Abwickelrichtung A übereinstimmenden Vorschub- und Bearbeitungsrichtung A'.
    • A first solution for this is a process for processing flexibly rolled strip material wound on coils with periodically changing material thickness in individual presses, transfer tools or transfer line to individual sheet metal formed parts with the sequence of the processing steps:
  • 1. Unwinding of the flexibly rolled strip material in a coil coiler,
  • 2. cutting to length of individual mutually identical boards with a greater length L than width B transversely to the unwinding direction A of the strip,
  • 3. twisting of the individual blanks by 90 ° in the strip material plane,
  • 4. stepwise advancing and processing of the individual boards in a match with the unwinding A feed and processing direction A '.

    • Eine geeignete Vorrichtung hierfür umfaßt eine Vorrichtung zur Verarbeitung von auf Coils aufgewickeltem flexibel gewalzten Bandmaterial mit periodisch veränderlicher Banddicke in Einzelpressen, Transferwerkzeugen oder Transferstraßen zu einzelnen Blechumformteilen,
    mit einer Haspelvorrichtung zum Abwickeln des Bandmaterials vom Coil,
    einer Bandtrenn- oder Scherenvorrichtung zum Abtrennen einzelner Platinen mit größerer Länge L als Breite B quer zur Abwickelrichtung A,
    einer 90°-Verdrehvorrichtung zum Verdrehen der einzelnen Platinen in der Materialebene um 90°,
    sowie bezüglich ihrer Vorschub- und Bearbeitungsrichtung A' in Übereinstimmung mit der Abwickelrichtung angeordneten Einzelpressen, Transferwerkzeugen oder Transferstraßen, deren Werkzeuge an die Lage der um 90° verdrehten Platinen (16) angepaßt sind.    A suitable apparatus for this purpose comprises a device for processing flexibly rolled strip material wound on coils with periodically variable strip thickness in individual presses, transfer tools or transfer lines to individual sheet-metal formed parts,
    with a reeling device for unwinding the strip material from the coil,
    a strip separating or shearing device for separating individual boards with a greater length L than width B transversely to the unwinding direction A,
    a 90 ° twisting device for rotating the individual boards in the material plane by 90 °,
    and with respect to their feed and machining direction A 'arranged in accordance with the unwinding single presses, transfer tools or transfer lines, whose tools are adapted to the position of the rotated by 90 ° boards (16).

    Durch das erfindungsgemäße Verdrehen der einzelnen abgelängten Platinen kommen diese mit ihren ursprünglichen Seitenkanten des Bandmaterials aneinander zu liegen, so daß die einzelnen Platinen bezüglich ihrer Vorschub- und Bearbeitungsrichtung mit ihrer ursprünglichen Breite hintereinander gestaffelt sind. Hierdurch läßt sich eine geringere Länge der Vorschubschritte und eine engere Staffelung der einzelnen Maschinen bzw. der einzelnen Werkzeuge innerhalb der Maschinen darstellen. Es können damit kürzere Taktzeiten dargestellt werden. Ebenso ist eine raumsparende Maschinenausführung und Werkzeuganordnung möglich.By twisting the individual cut-to-length boards according to the invention come these with their original side edges of the strip material to each other lie, so that the individual boards with respect to their feed and processing direction staggered with their original width in a row. This leaves a shorter length of the feed steps and a closer staggering of the individual Represent machines or individual tools within the machines. It can be displayed with shorter cycle times. Likewise is a space-saving Machine design and tool arrangement possible.

    Eine zweite Lösung besteht in einem Verfahren zur Verarbeitung von auf Coils aufgewickeltem flexibel gewalzten Bandmaterial mit sich periodisch ändernder Materialdicke in Einzelpressen, Transferwerkzeugen oder Transferstraße zu einzelnen Blechumformteilen mit der Abfolge der Bearbeitungschritte:

  • 1. Abwickeln des flexibel gewalzten Bandmaterials in einer Haspelvorrichtung vom Coil,
  • 2. Ablängen einzelner untereinander gleicher Platinen mit größerer Länge L als Breite B quer zur Abwickelrichtung A des Bandes,
  • 3. Ändern der Transportrichtung der Platinen von der Abwickelrichtung A in eine davon um 90° abweichende Vorschub- und Bearbeitungsrichtung Aquer,
  • 4. Schrittweises Vorschieben und Bearbeiten der einzelnen Platinen unter Beibehaltung der geänderten Vorschub- und Bearbeitungsrichtung Aquer.
    • A second solution consists in a method for processing flexibly rolled strip material wound on coils with periodically changing material thickness in individual presses, transfer tools or transfer line to individual sheet metal formed parts with the sequence of the processing steps:
  • 1. Unwinding of the flexibly rolled strip material in a coil coiler,
  • 2. cutting to length of individual mutually identical boards with a greater length L than width B transversely to the unwinding direction A of the strip,
  • 3. changing the transport direction of the blanks from the unwinding direction A into one of them deviating by 90 ° feed and processing direction A trans ,
  • 4. Stepwise advancement and processing of the individual boards while maintaining the changed feed and machining direction A across .

    • Eine entsprechende Vorrichtung hierfür umfaßt eine Vorrichtung zur Verarbeitung von auf Coils aufgewickeltem flexibel gewalzten Bandmaterial mit periodisch veränderlicher Banddicke in Einzelpressen, Transferwerkzeugen oder Transferstraße zu einzelnen Blechumformteilen,
    mit einer Haspelvorrichtung zum Abwickeln des Bandmaterials vom Coil,
    einer Bandtrenn- oder Scherenvorrichtung zum Abtrennen einzelner Platinen mit größerer Länge L als Breite B quer zur Abwickelrichtung A,
    einer 90°-Transportrichtungsänderungseinheit zum Ändern der Transportrichtung der einzelnen Platinen in der Materialebene,
    sowie bezüglich ihrer Vorschub- und Bearbeitungsrichtung A quer unter einem rechten Winkel zur Abwickelrichtung A angeordneten Einzelpressen, Transferwerkzeugen oder Transferstraße, deren Werkzeuge an die Lage der quer transportierten Platinen angepaßt sind.     A corresponding device for this purpose comprises a device for processing flexibly rolled strip material wound on coils with periodically variable strip thickness in individual presses, transfer tools or transfer line to individual sheet-metal formed parts,
    with a reeling device for unwinding the strip material from the coil,
    a strip separating or shearing device for separating individual boards with a greater length L than width B transversely to the unwinding direction A,
    a 90 ° transport direction changing unit for changing the transport direction of the individual boards in the material plane,
    and with respect to their feed and machining direction A transversely at a right angle to the unwinding A arranged single presses, transfer tools or transfer line, the tools are adapted to the position of the cross-transported boards.

    Bei der hiermit vorgeschlagenen Lösung kann eine Platinendrehvorrichtung eingespart werden. Das Wesen liegt in diesem Falle darin, daß nach dem Vereinzeln der Platinen deren Vorschubrichtung und damit die nachfolgende Bearbeitungsrichtung um 90° im Verhältnis zur ursprünglichen Abwickelrichtung geändert wird. Es ergeben sich hierdurch die gleichen zuvor genannten Vorteile der dichteren Staffelung der einzelnen Platinen mit aneinanderliegenden ursprünglichen Seitenkanten des Bandmaterials in Vorschubrichtung. Daraus folgend werden auch hier geringe Taktzeiten und günstige Anordnungs- und Gestaltungsmöglichkeiten für die Werkzeuge und Maschinen erschlossen.In the solution proposed hereby, a board turning device can be saved become. The essence lies in this case in the fact that after the separation of the Blanks their feed direction and thus the subsequent processing direction changed by 90 ° in relation to the original unwinding direction. It revealed This gives the same advantages of denser staggering individual boards with abutting original side edges of the strip material in the feed direction. As a result, even here are low cycle times and favorable arrangement and design options for the tools and Machines opened up.

    Nach einer besonders günstigen Ausführung werden die einzelnen Platinen nicht gemäß fester Längseinstellung sondern aufgrund einer Detektierung der einzelnen Bandperioden abgetrennt. Entsprechend muß eine Detektiereinheit für die Banddicke zur Steuerung der Bandschere vorgesehen werden.After a particularly favorable design, the individual boards are not according to fixed longitudinal adjustment but due to a detection of the individual Band periods separated. Accordingly, a tape thickness detection unit must be provided be provided for controlling the band scissors.

    In weiterhin günstiger Ausführung ist eine Bandspeichereinheit vor der Bandschere zum Abtrennen der einzelnen Platinen vorgesehen, d. h. das flexibel gewalzte Material wird nach dem Durchlaufen eines Richtstuhls zur Geschwindigkeitsentkopplung durch eine Schlingengrube geführt. Am Auslauf der Schlingengrube befindet sich das genannte Detektiersystem, um die Schnittpositionen im Bandmaterial zu definieren. Diese Schnittposition wird geschwindigkeitssynchron auf die Querteilschere übertragen. Die Platine wird somit vor der Presse in Längsorientierung aus dem Bandmaterial geschnitten. Um beim Abhaspeln Coilknicke zu vermeiden, kann das flexibel gewalzte Material mittels einer Anti-Coil-Rolle in der Haspelvorrichtung abgewickelt werden und von da zum genannten Richtstuhl laufen, der geeignet ist, unterschiedliche Blechdicken gleichförmig zu richten.In further favorable execution is a tape storage unit in front of the band shears provided for separating the individual boards, d. H. the flexibly rolled material becomes after speeding through a Richtstuhls for speed decoupling passed through a loop pit. At the outlet of the loop pit is the called detection system to define the cutting positions in the strip material. This cutting position is transmitted synchronously to the cross cutting shear. The board is thus before the press in longitudinal orientation of the strip material cut. To avoid coil creases during unwinding, this can be flexibly rolled Material unwound by means of an anti-coil role in the coiler and from there to the mentioned Richtstuhl run, which is suitable, different Align sheet thicknesses uniformly.
