Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Längsrandbearbeitungsvorrichtung der eingangs genannten Art bereit zu stellen, die die Bearbeitung von Blechplatten, beispielsweise für die Herstellung von Rohren vereinfacht.The present invention has for its object to provide a longitudinal edge processing device of the type mentioned, which simplifies the processing of metal plates, for example, for the production of pipes.
Diese Aufgabe wird mit den Merkmalen des Anspruches 1 gelöst. Hierbei ist vorgesehen, dass die untere und die obere Formwerkzeuganordnung über die gesamte Länge des Längsrandes des Bleches erstreckt sind und von denen zumindest die obere oder die untere Formwerkzeuganordnung zum Ausführen des Anbiegeprozesses in vertikaler Richtung bezüglich der Blechplatte verstellbar und mit einstellbarer Biegekraft in Verstellrichtung beaufschlagbar ist.This object is achieved with the features of
Vorteil der so ausgebildeten Längsrandbearbeitungsvorrichtung ist, dass sich das Anbiegen und Bearbeiten der Kanten in derselben Anlage mit relativ wenig Aufwand zuverlässig durchführen lassen, auch wenn dicke Bleche vorliegen, wie sie für Rohre großen Durchmessers (z. B. größer als 50 cm) verwendet werden.The advantage of the longitudinal edge machining device formed in this way is that the bending and machining of the edges in the same installation can be carried out reliably with relatively little effort, even if thick sheets are present, such as are used for pipes of large diameter (for example greater than 50 cm) ,
Ein für die Steuerung des Biegeprozesses vorteilhafter Aufbau besteht darin, dass die untere und/oder die obere Formwerkzeuganordnung zum Verstellen an eine hydraulische Verstellvorrichtung angeschlossen ist/sind.An advantageous for the control of the bending process construction is that the lower and / or the upper mold assembly is connected for adjusting to a hydraulic adjusting device / are.
Für den Aufbau und die Funktion sind des Weiteren die Merkmale von Vorteil, dass die untere und/oder die obere Formwerkzeuganordnung in zum Längsrand des Bleches paralleler Richtung aus mehreren Segmenten aufgebaut ist/sind.Furthermore, the features of the structure and the function are advantageous in that the lower and / or the upper die arrangement is / are constructed in a direction parallel to the longitudinal edge of the metal sheet from a plurality of segments.
Eine gute Anpassung an unterschiedliche Bleche und Biegeradien ergibt sich dadurch, dass die Segmente der unteren Formwerkzeuganordnung jeweils einen Stellzylinder und einen Formwerkzeugstempel mit Pressschuh und die Segmente der oberen Formwerkzeuganordnung jeweils einen weiteren Stellzylinder und einen weiteren Formstempel mit einem weiteren Pressschuh aufweisen. Dabei kann die Ausbildung derart sein, dass die Pressschuhe austauschbar sind.A good adaptation to different plates and bending radii results from the fact that the segments of the lower mold assembly each have a control cylinder and a mold punch with press shoe and the segments of the upper mold assembly each have a further actuating cylinder and another Have mold with another press shoe. The training may be such that the press shoes are interchangeable.

Die Blechbearbeitung wird ferner dadurch begünstigt, dass die Kantenbearbeitungsvorrichtung bezüglich des Längsrandes des zu bearbeitenden Bleches außerhalb der Biegevorrichtung angeordnet ist, wobei ein Bearbeitungswerkzeug entlang dem Längsrand verfahrbar ist. Hierdurch kann die geometrische Ausdehnung der Anlage relativ platzsparend ausgeführt werden.The sheet metal processing is further facilitated by the fact that the edge processing device is arranged outside the bending device with respect to the longitudinal edge of the sheet to be processed, wherein a processing tool can be moved along the longitudinal edge. As a result, the geometric extension of the system can be carried out relatively space-saving.
Eine vorteilhafte Ausgestaltung für die Kantenbearbeitung besteht darin, dass das Bearbeitungswerkzeug ein Fräswerkzeug ist.An advantageous embodiment for edge processing is that the machining tool is a milling tool.
Ist vorgesehen, dass zusätzlich eine Richtvorrichtung zum Richten wellenförmiger Bleche vorhanden ist, können auch wellenförmige Bleche in derselben Anlage für die weitere Bearbeitung vorbereitet werden. Beispielsweise kann das Richten durch die sich in Längsrichtung über das Blech erstreckende Biegevorrichtung bewirkt werden oder es kann eine zusätzliche Anordnung von Richtmitteln vorgesehen sein.It is envisaged that in addition a straightening device for straightening wave-shaped sheets is available, wave-shaped sheets can be prepared in the same system for further processing. For example, the straightening may be effected by the bending device extending longitudinally over the sheet, or an additional arrangement of straightening means may be provided.
Eine automatische Durchführung des Biegeprozesses wird dadurch zuverlässig erreicht, dass die Einspannvorrichtung und die Biegevorrichtung an eine gemeinsame Steuerungseinrichtung angeschlossen sind, die zur aufeinander abgestimmten Einspannung und Biegesteuerung ausgebildet ist.An automatic implementation of the bending process is achieved reliably in that the clamping device and the bending device are connected to a common control device, which is designed for coordinated clamping and bending control.
Weiterhin tragen die Maßnahmen, dass auch die Zuführvorrichtung und die Kantenbearbeitungsvorrichtung an die Steuerungseinrichtung angeschlossen sind, zu einer vereinfachten automatischen Bearbeitung bei.Furthermore, the measures that also the feeding device and the edge processing device are connected to the control device contribute to a simplified automatic processing.
Eine vorteilhafte weitere Ausgestaltung für die Bearbeitung besteht darin, dass die Biegevorrichtung zum Anbiegen ausgebildet ist, und dass die Einspanneinrichtung eine Widerlagereinrichtung aufweist, die zum Bewirken der für das Anbiegen aufzubringenden Gegenkräfte ausgebildet ist, wobei die Blechspannvorrichtung mit Presszylindern und Pressschuhen so dimensioniert ist, dass ein Fixieren des Bleches sowohl beim Fräsen, Hobeln oder Schneiden als auch beim Anbiegen und/oder Richten sichergestellt ist.An advantageous further embodiment for the machining is that the bending device is designed for bending, and that the clamping device has an abutment device, which is designed to effect the counterforces to be applied for the bending, wherein the sheet clamping device is dimensioned with pressing cylinders and press shoes so that a fixing of the sheet both during milling, planing or cutting and when bending and / or straightening is ensured.
Anstelle eines Fräswerkzeugs für die Kantenbearbeitung kann auch ein Hobelwerkzeug oder ein anderes Schneidwerkzeug (z. B. Säge) vorgesehen sein.Instead of a milling tool for edge processing, a planing tool or another cutting tool (eg saw) may also be provided.

Außerhalb des Blech-Längsrandes ist ferner eine Kantenbearbeitungseinrichtung 30 angeordnet, die an den Blechrand verfahrbar ist oder der das Blech B mittels der Zuführvorrichtung 20 zuführbar ist. Zur Bearbeitung der oberen und/oder unteren Blechkante ist das Bearbeitungswerkzeug der Kantenbearbeitungseinrichtung 30 entsprechend geformt, um z. B. eine Schweißnahtvorbereitung in V-, Y- oder X-Form herzustellen. Das Bearbeitungswerkzeug ist vorzugsweise ein Fräswerkzeug, kann aber auch ein Hobelwerkzeug oder anderes Schneidewerkzeug sein. Zur Bearbeitung kann der Aufbau so ausgeführt sein, dass das Bearbeitungswerkzeug entlang der Blech-Längskante bei ruhendem Blech B bewegt wird oder das Blech B entlang dem ruhenden Bearbeitungswerkzeug bewegt wird.Outside the sheet longitudinal edge, an
Ferner ist eine Einspannvorrichtung 10 vorgesehen, mit der das plattenförmige Blech B gegen die Auflage 14 oder eine andere Abstützung 11 (vgl.
Die Steuerung der Zuführvorrichtung 20, der Einspannvorrichtung 10 und der Anbiegevorrichtung erfolgt mittels einer gemeinsamen Steuerungseinrichtung 5 abgestimmt aufeinander, wobei auch die Steuerung der Kantenbearbeitungseinrichtung 30 mit in die Steuerung durch die Steuerungseinrichtung 5 einbezogen sein kann. Zunächst wird für die Bearbeitung das Blech B mittels der Zuführvorrichtung an die Bearbeitungsstelle der Kantenbearbeitungseinrichtung 30 geführt und dann die Einspannvorrichtung 10 betätigt. Sodann erfolgt die Steuerung der Anbiegevorrichtung. Anschließend kann die so an ihrem Rand bearbeitete Blechplatte gedreht und entlang ihrem anderen Längsrand mit derselben Biegevorrichtung und Kantenbearbeitungseinrichtung entsprechend bearbeitet werden. Alternativ kann entlang dem anderen Blech-Längsrand eine entsprechende Randbearbeitungsvorrichtung vorgesehen sein, so dass auch eine parallele entsprechende Bearbeitung der beiden Längsränder gleichzeitig oder zeitversetzt durchgeführt werden kann. Nach der Längsrandbearbeitung kann das Blech B dann dem weiteren Biegeprozess zugeführt werden, beispielsweise in einer getrennten Anlage.The control of the

Die
Die der Oberseite der Blechplatte B zugekehrten Endabschnitte der Formwerkzeugstempel 1 sind mit Pressschuhen 1.1 versehen, deren Enden konisch angeschrägt oder konvex nach außen gerundet sind, so dass sie den Biegevorgang entsprechend der eingestellten Krümmung begünstigen. Auch der zur Unterseite der Blechplatte B gerichtete Endabschnitt der betreffenden Formstempel 3 ist mit einem weiteren Pressschuh 4 versehen, dessen zu der unteren Oberfläche der Blechplatte B hin gerichtete Stirnfläche ebenfalls konisch abgeschrägt oder konvex nach außen gerundet ist, so dass zu Beginn der Biegebearbeitung die flache Blechplatte B lediglich punktartig oder linienartig auf dem Pressschuh 4 aufliegt und beim Biegevorgang eine Neigungsänderung der unteren Blechoberfläche relativ zur Stirnseite des Pressschuhs 4 ungehindert fortschreiten kann, wodurch der Biegevorgang zusätzlich begünstigt wird. Die Formwerkzeugstempel 1 und die Formstempel 3 werden vorzugsweise mittels hydraulisch angetriebener Stellglieder, insbesondere Stellzylinder 2 bzw. 6, zur Einstellung auf die vorgegebene Krümmung einerseits und für den Biegevorgang andererseits betätigt, wobei die Steuerung oder Regelung der Betätigung mittels der Steuerungseinrichtung 5 erfolgt. Anstelle eines hydraulischen Antriebs kann insbesondere für die Formstempel 3 ein pneumatischer Antrieb vorgesehen sein. Sind die Pressschuhe 1.1 und/oder weiteren Pressschuhe 4 bei einer Ausführungsvariante auswechselbar an den Endabschnitten der Formwerkzeugstempel 1 bzw. der Formstempel 3 angebracht, so können Pressschuhe 1.1, 4 mit unterschiedlich geformter Stirnseite leicht gegeneinander ausgetauscht werden, oder sie können bei Verschleiß einfach ersetzt werden. Auch wird durch den Austausch von Pressschuhen 1.1 bzw. 4 eine Anpassung an unterschiedliche Materialien zu biegender Blechplatten B ermöglicht. Bei der Abstimmung der Materialpaarung Pressschuhe/Blechplatte ist es vorteilhaft, den Reibwert so zu wählen, dass eine Rutschhemmung erreicht wird oder aber eine gute Gleitfähigkeit je nach Biegekontur oder Blechmaterial, Blechstärke oder dgl.The top of the metal plate B facing end portions of the
Bei einer alternativen Ausgestaltung ist vorgesehen, dass die Reihe der Formstempel 3 für den Biegevorgang mit der zugehörigen Antriebseinrichtung über der Oberseite der Blechplatte B angeordnet ist, während die Reihen der Formwerkzeugstempel 1 für die Einstellung der Krümmung unter der Unterseite der Blechplatte B angeordnet sind.In an alternative embodiment, it is provided that the row of forming dies 3 is arranged for the bending operation with the associated drive means on top of the sheet metal plate B, while the rows of
Mittels der Steuerungseinrichtung 5 können die Einstellung der Formwerkzeugstempel 1 auf die vorgegebene Krümmung und die Ansteuerung der Formstempel 3 für den Biegevorgang in Abstimmung aufeinander erfolgen, wozu die Steuerung eine für eine Programmierung geeignete Rechnereinheit aufweist. Vorteilhaft weist die Blechbiegemaschine ein Messsystem mit einer Messsensorik auf, welches die Kontur des Bleches beim Anbiegen und gegebenenfalls weiteren Einbiegen aufnimmt und dessen Daten der Steuerungseinrichtung zugeführt und in dieser verarbeitet werden, um die Biegedaten anzupassen. Ferner umfasst die Steuerungseinrichtung 5 vorteilhaft eine Speichereinrichtung, in der Vorgabewerte für die Bearbeitung bestimmter Produkttypen hinterlegt und für den Bediener leicht abrufbar sind. Mit der Steuerungseinrichtung 5 kann auch die Einspannvorrichtung 10 gekoppelt sein, um die Spannanordnung 12 beim Zuführen oder Abnehmen der Blechplatte B freizugeben und beim Bearbeiten während des Biegevorgangs und der Kantenbearbeitung einzuspannen. Für einen automatisierten Ablauf ist weiterhin vorteilhaft vorgesehen, dass auch die Zuführvorrichtung 20 für die Blechplatte B an die Steuerungseinrichtung 5 angeschlossen und von dieser gesteuert wird. Damit kann die Zuführung der Blechplatte B zu der Bearbeitungsstelle für das Biegen und/oder Bearbeiten der Kante(n) mittels der Steuerungseinrichtung 5, abgestimmt auf den Biegevorgang bzw. die Kantenbearbeitung und die Einspannung, erfolgen. Die Einspannvorrichtung 10 ergibt eine eindeutige Festlegung der Blechplatte B, so dass die Biegung über die Reihen der mit den Pressschuhen 1.1 versehenen Formwerkzeugstempel 1 bei stabiler Ausrichtung und mit hoher Genauigkeit durchgeführt werden kann. Dabei bietet die Abstützung 11 mit ihrer Stirnseite eine eindeutige Bezugslage für die Einstellung der Formwerkzeugstempel 1 und die darüber vorgegebene Krümmung der Blechplatte B, wobei die jeweilige Stärke der Blechplatte B in der Steuerungseinrichtung 5 zur erforderlichen Kraftbeaufschlagung mit berücksichtigt wird.By means of the
Mit der Biegemaschine kann das Anbiegen und, bei entsprechender Ausbildung, die gewünschte Form des Bleches, beispielsweise eine zylindrische Rohrform, einfach und genau über die mittels der Steuerung bzw. Regelung vorgegebene Einstellung der hydraulischen oder pneumatischen Stellzylinder mittels einer Segmentbiegebearbeitung und Endstellung der Reihen der Formwerkzeugstempel 1 erreicht werden, wobei unterschiedliche Einstellungen einfach und genau ermöglicht werden. Die Reihen der Formwerkzeugstempel 1 sind dabei mit ihren Stirnseiten auf gleiche Höhenlage bzw. gleichen Abstand von der betreffenden Oberfläche der Blechplatte B eingestellt, während der Abstand von Reihe zu Reihe zur Kante des bearbeiteten
Blechabschnitts hin zunehmend entlang einer Geraden oder konvex nach außen gekrümmten Kurve zunehmen kann. Beim Biegen des Bleches mittels der Formstempel 3 treten somit die einzelnen Reihen der Formwerkzeugstempel 1 mit ihren Stirnseiten bzw. Pressschuhen 1.1 zur Blechkante hin nacheinander mit der betreffenden Oberfläche des Blechs in Kontakt, wobei sich der Hebelarm zwischen der betreffenden Reihe der Formwerkzeugstempel 1 und der Reihe der Formstempel 3 zunehmend verkürzt und damit die aufzubringenden Biegekräfte erhöhen. Vorzugsweise sind die Formstempel 3 für höhere Kräftebeanspruchungen ausgelegt als die Formwerkzeugstempel 1, da sie auch dynamisch stärker beansprucht werden. Einem Pressschuh 4 können mehrere Formstempel 3 mit hydraulischen bzw. pneumatischen Antrieben zugeordnet sein, so dass die Anzahl der weiteren Pressschuhe 4 in diesem Falle geringer ist als die Anzahl der Formstempel 3. Auch kann insgesamt die Anzahl der Formstempel 3 in einer Reihe geringer sein als die Anzahl der Formwerkzeugstempel 1 in einer Reihe, wodurch die dynamische Steuerung der Formstempel 3 begünstigt und auch Verschleißteile verringert werden. Um bis zu der der betreffenden Blechkante am nächsten liegenden Reihe der Formwerkzeugstempel 1 eine zuverlässige Anbiegung oder Biegung durchzuführen, ist die Reihe der Formstempel 3 höchstens so weit von der Blechkante entfernt, wie die dieser am nächsten liegende Reihe der Formwerkzeugstempel 1.With the bending machine, the bending and, with appropriate training, the desired shape of the sheet, such as a cylindrical tube shape, easily and accurately on the means of the control or regulation predetermined adjustment of the hydraulic or pneumatic actuating cylinder by means of a segment bending processing and end position of the rows of
Sheet increasingly towards along a straight line or convex curved outward curve can increase. When bending the sheet metal by means of the forming dies 3, the individual rows of the forming dies 1 with their end faces or press shoes 1.1 come into contact with the sheet metal edge in succession with the relevant surface of the sheet, with the lever arm between the relevant row of the forming dies 1 and the row the forming
Mittels der Steuerungseinrichtung 5 kann die Steuerung bzw. Regelung beim Anbiegen bzw. Biegen auf die Eigenschaften unterschiedlicher Materialien des Werkzeugs der Blechplatte B geeignet abgestimmt werden.By means of the
Eine ähnliche Ausführung einer Längsrandbearbeitungsvorrichtung wie in
Mit den gezeigten Biegevorrichtungen wird ein ungünstiges Quetschen des Blechrandes vermieden, wobei die Blechrandbearbeitung rationell durchführbar ist und auch dicke Bleche von z. B. mehr als 30 mm oder 50 mm für Rohre großen Durchmessers (z. B. größer als 300 mm oder 500 mm) exakt gebogen werden können.With the bending devices shown unfavorable squeezing of the sheet edge is avoided, the sheet edge machining is rationally feasible and thick sheets of z. B. more than 30 mm or 50 mm for pipes of large diameter (eg greater than 300 mm or 500 mm) can be bent exactly.
