Abstract
Description
Die vorliegende Erfindung betrifft ein Stanzwerkzeug, wie es zum Beispiel in einer Folienverarbeitungsanlage zum Einsatz kommen kann, um den Rand einer beschichteten Endlosfolie zu beschneiden.The present invention relates to a punching tool, such as may be used in a film processor to trim the edge of a coated continuous film.
Bei Folienverarbeitungsanlagen kommen gelegentlich bewegte Stanzwerkzeuge zum Einsatz. Das in Bandform vorliegende Folienmaterial wird in einer Materialvorschubrichtung kontinuierlich fortwährend bewegt. Das Stanzwerkzeug weist ein Oberwerkzeug und ein Unterwerkzeug auf, wobei das Oberwerkzeug über dem Folienmaterial und das Unterwerkzeug unter dem Folienmaterial angeordnet ist. Zur Durchführung des Stanzvorgangs wird das sich schließende Stanzwerkzeug synchron zur Bewegung des Folienmaterials mit diesem mitbewegt. Nach Durchführung des Stanzhubs öffnet das Stanzwerkzeug und wird dann wieder in Ausgangsposition zurück bewegt. Das Stanzwerkzeug führt somit nicht nur eine Öffnungs- und Schließbewegung, sondern zusätzlich eine Hin- und Herbewegung in und gegen die Folientransport-. bzw. gegen die Werkstücktransportrichtung durch. Die Stanzeinheit bewegt sich jeweils für die Dauer eines Stanzvorgangs mit der durchlaufenden Folie. Anschließend geht es in geöffnetem Zustand in seine Ursprungsposition zurück, um dann den nächsten Folienabschnitt zu bearbeiten.Film processing equipment sometimes uses moving punching tools. The sheet material in strip form is continuously continuously moved in a material feeding direction. The punching tool has an upper tool and a lower tool, wherein the upper tool is arranged above the film material and the lower tool below the film material. To carry out the punching process, the closing punching tool is moved along with it in synchronism with the movement of the foil material. After the punching stroke has been carried out, the punching tool opens and is then moved back into its original position. The punching tool thus not only performs an opening and closing movement, but also a reciprocating movement in and against the film transport. or against the workpiece transport direction. The punching unit moves in each case for the duration of a punching operation with the continuous film. Afterwards, it returns to its original position in the opened state, in order to then process the next film section.
Weil das Stanzwerkzeug auf einem Träger montiert und nicht fest mit dem Maschinengestell verbunden ist, sondern vielmehr eine fortwährende Vorwärts- und Rückwärtsbewegung ausführt, wirken Beschleunigungskräfte auf den Stanzstempel und die Schnittplatte, was zu Genauigkeitsproblemen führen kann. Sollen dünne und empfindliche Folien gestanzt werden und/oder werden besonders hohe Genauigkeitsanforderungen an die durchzuführenden Stanzschnitte bzw. an deren Qualität gestellt, kann es schwierig werden, die geforderte Präzision des Stanzvorgangs sicherzustellen.Because the punching tool is mounted on a carrier and is not fixedly connected to the machine frame, but rather performs a continuous forward and backward movement, acceleration forces act on the punch and the cutting plate, which can lead to accuracy problems. If thin and sensitive films are to be punched and / or if particularly high accuracy requirements are placed on the die cuts to be performed or on their quality, it may be difficult to ensure the required precision of the punching process.
Es ist Aufgabe der Erfindung, hier abzuhelfen und Maßnahmen anzugeben, durch die sich insbesondere bei beweglich gelagerten Stanzwerkzeugen hohe Genauigkeitsansprüche erfüllen lassen.It is an object of the invention to remedy this situation and to provide measures by which high accuracy requirements can be met, in particular in the case of movably mounted punching tools.
Diese Aufgabe wird mit dem Stanzwerkzeug nach Anspruch 1 gelöst:
- Das erfindungsgemäße Stanzwerkzeug eignet sich insbesondere zur Folienbearbeitung, insbesondere zur Bearbeitung dünner Metallbleche oder Metallfolien. Das erfindungsgemäße Stanzwerkzeug gestattet die Erlangung einer hohen Bearbeitungspräzision, auch bei schwierigen Verhältnissen, beispielsweise in Folge höchster Genauigkeitsanforderungen, hoher Stanzgeschwindigkeit, problematischer Folienmaterialien und/oder fortlaufender hin und her gehender Längsbewegung des Stanzwerkzeugs oder dergleichen. Beispielsweise kann das zu verarbeitende Folienmaterial eine Folie sein, wie sie für Hochleistungsakkumulatoren verwendet wird. Es kann sich bei der Folie um eine mit einer Kobalt-Graphit-Mischung beschichtete Kupferfolie handeln. Die typische Dicke kann zum Beispiel bei 0,2 mm liegen, wobei die Kupferschicht dann nur etwa 0,01 mm dick ist. Die Verarbeitung dieser Folie erfordert die Verwendung sehr scharf geschliffener Stanzstempel und die Einhaltung sehr enger Schneidspalte. Dies zu erreichen ist mit der Erfindung auch dann möglich, wenn das Stanzwerkzeug, wie eingangs beschrieben, zur Durchführung des Stanzvorgangs jeweils mit der Folie mitbewegt und danach in seiner Ausgangsposition zurückgeführt wird, also zusätzlich zu seiner Stanzbewegung eine in Folientransportrichtung hin und her gehende Bewegung ausführt.
- Das Stanzwerkzeug weist mindestens einen Stanzstempel auf, der an der Kopfplatte mit Beweglichkeit in mindestens einer quer zu der Stanzhubrichtung orientierten Querrichtung verbunden ist. Das zwischen dem Stanzstempel und der Kopfplatte gegebene Spiel entkoppelt die Querposition des Stempels von der Kopfplatte. Der Stempel ist somit an der Kopfplatte schwimmend gelagert. Die Relativpositionierung des Stempels zur zugehörigen Stanzöffnung wird nun nicht mehr von dem Gestell übernommen, sondern von der Stempelführungseinrichtung, die zwischen dem Stanzstempel und der Schnittplatte unmittelbar wirksam ist. Auf diese Weise kann eine äußerst präzise Relativpositionierung zwischen dem Stempel und der Schnittplatte erzielt werden, und zwar unabhängig von Beschleunigungs- oder Bremskräften, die durch das ständige hin und her bewegen des gesamten Stanzwerkzeugs in Werkstücktransportrichtung auf den Stempel bzw. die Schnittplatte einwirken. Es lässt sich deshalb auch bei hoher Arbeitsgeschwindigkeit eine hohe Präzision erreichen. Es sei allerdings darauf hingewiesen, dass sich die Erfindung nicht nur zum Einsatz an bewegten Stanzwerkzeugen, sondern auch zum Einsatz an ruhenden Stanzwerkzeugen eignet, wenn dort eine sehr hohe Präzision erreicht werden soll. Auch ist es möglich, den oder die Stempel an der Kopfplatte fest anzuordnen und die Schnittplatte oder Schnittplattenabschnitte relativ zu dem Stempel in Querrichtung beweglich zu lagern. Wiederum bewirkt die Stempelführungseinrichtung die präzise Relativausrichtung von Stempel und Schnittplatte, bzw. von deren Schneidkanten.
- The punching tool according to the invention is particularly suitable for film processing, in particular for processing thin metal sheets or metal foils. The punching tool according to the invention allows the achievement of a high machining precision, even in difficult conditions, for example as a result of highest accuracy requirements, high punching speed, problematic film materials and / or continuous reciprocating longitudinal movement of the punch or the like. For example, the sheet material to be processed may be a sheet used for high capacity accumulators. The film may be a copper foil coated with a cobalt-graphite mixture. The typical thickness may be, for example, 0.2 mm, with the copper layer then only about 0.01 mm thick. The processing of this film requires the use of very sharp ground punches and compliance with very narrow cutting gaps. To achieve this is possible with the invention even if the punching tool, as described above, to carry out the punching process in each case with the film moved along and then returned to its original position, so in addition to its punching movement in the direction of film transporting back and forth movement performs.
- The punching tool has at least one punch, which is connected to the top plate with mobility in at least one transversely oriented to the punching stroke transverse direction. The clearance between the punch and the top plate decouples the transverse position of the punch from the top plate. The stamp is thus floating on the top plate. The relative positioning of the punch to the associated punch opening is no longer taken over by the frame, but by the punch guide means which is directly effective between the punch and the cutting plate. In this way, a highly precise relative positioning between the punch and the cutting plate can be achieved, regardless of acceleration or braking forces acting on the punch or the cutting plate by the constant reciprocating movement of the entire punching tool in the workpiece transport direction. It is therefore possible to achieve high precision even at high operating speeds. It should be noted, however, that the invention is not only suitable for use on moving punching tools, but also for use on stationary punching tools, if a very high precision is to be achieved there. It is also possible to arrange the punch or stamps firmly on the top plate and to mount the cutting plate or cutting plate sections in a movable manner relative to the stamp in the transverse direction. Again, the punch guide device effects the precise relative alignment of the punch and the cutting plate, or of their cutting edges.
Der Stanzstempel ist vorzugsweise mindestens in einer quer zur Werkstücktransportrichtung orientierten Querrichtung bewegbar gelagert. Dazu kann er in einer entsprechenden Gleitführung gefasst sein. Sollen die Ränder eines durchlaufenden Materialbands oder sonstigen Werkstücks beschnitten werden, können an den entsprechenden Stellen des Stanzwerkzeugs zwei voneinander unabhängig schwimmend gelagerte Stempel vorgesehen sein, die jeweils in der genannten Querrichtung beweglich gehalten sind, also (Quer-)Spiel haben. Die Stempelführungseinrichtungen der beiden Stempel führen die Stempel an der Schnittplatte und stellen so das ordnungsgemäße Zusammenspiel zwischen dem jeweiligen Stempel und der jeweiligen Stanzöffnung sowie außerdem auch die präzise Einhaltung des Abstands der beiden von den Stempel erzeugten Schnittkanten an dem Werkstück sicher.The punch is preferably at least in one Transversely mounted transversely to the workpiece transport direction oriented transverse direction. For this he can be caught in a corresponding slide. If the edges of a continuous material band or other workpiece are to be trimmed, two mutually independently floating stamps can be provided at the corresponding points of the punching tool, which are each held movably in said transverse direction, ie have (transverse) play. The punch guiding devices of the two punches guide the punches on the cutting plate and thus ensure the proper interaction between the respective punches and the respective punching opening as well as the precise adherence to the distance between the two cut edges produced by the punches on the workpiece.
Das Stanzwerkzeug weist vorzugsweise an zwei einander gegenüber liegenden Seiten offene Durchgänge auf, durch die das bandförmige Werkstück in das Stanzwerkzeug ein- und austreten kann. Die Stempelführungseinrichtungen sind vorzugsweise seitlich neben dem durchlaufenden, bandförmigen Werkstück angeordnet, d.h. außerhalb eines Werkstückdurchlaufraums. Dies schafft die Möglichkeit des dauernden Eingriffs der Stempelführungseinrichtung. Diese kann beispielsweise als Linearführung ausgebildet sein. Die Linearführung kann durch einen oder mehrere runde im Querschnitt polygonale, rechteckige oder anderweitig geformte Bolzen gebildet sein, die in entsprechende Führungsöffnungen greifen. Beispielsweise können der oder die Bolzen an dem Stempel und der oder die Führungsöffnungen an der Schnittplatte angeordnet sein. Es wird darauf hingewiesen, dass diese Anordnung auch umgekehrt werden, d.h. die Führungsbolzen an der Schnittplatte und die zugeordneten oder zugehörigen Führungsöffnungen an dem jeweiligen Stempel angeordnet sein können. Dies gilt sowohl für die Ausführungsform mit beweglichem Stempel und fester Schnittplatte wie auch für die Ausführungsform mit festem Stempel und beweglicher Schnittplatte. Jedenfalls wird aber bevorzugt, die Führungsbolzen und die Führungsöffnungen in dauerndem Eingriff zu belassen. Mit anderen Worten, die Führungsbolzen sind vorzugsweise länger als der Stanzhub des Stanzwerkzeugs. Außerdem erbringt der Führungsbolzen in der Führungsöffnung vorzugsweise nicht nur eine Querführung, sondern, falls gewünscht, auch eine Kippführung. Mit anderen Worten, die Führungseinrichtung hat vorzugsweise nur einen Freiheitsgrad. Dieser ist die Bewegung in Stanzhubrichtung.The punching tool preferably has passages open at two opposite sides, through which the band-shaped workpiece can enter and exit the punching tool. The punch guide devices are preferably arranged laterally next to the continuous band-shaped workpiece, ie outside a workpiece passage space. This provides the possibility of continuous engagement of the punch guide device. This can be formed for example as a linear guide. The linear guide can be formed by one or more round in cross-section polygonal, rectangular or otherwise shaped bolts which engage in corresponding guide openings. For example, the bolt or bolts may be arranged on the punch and the guide orifices or openings on the cutting plate. It should be noted that this arrangement can also be reversed, ie the guide pins on the cutting plate and the associated or associated guide openings can be arranged on the respective stamp. This applies both to the embodiment with movable punch and fixed cutting plate as well as for the Embodiment with fixed punch and movable cutting plate. In any case, it is preferred to leave the guide pins and the guide openings in permanent engagement. In other words, the guide pins are preferably longer than the punching stroke of the punching tool. In addition, the guide pin preferably provides not only a transverse guide in the guide opening, but also, if desired, a tilt guide. In other words, the guide device preferably has only one degree of freedom. This is the movement in punching stroke direction.
Die Stempelführungseinrichtung ist mit anderen Worten eine Linearführungseinrichtung, deren Führungsrichtung mit der Stanzrichtung übereinstimmt. Das Spiel der Linearführungseinrichtung wird im Hinblick auf die zu erreichende Präzision so gering wie möglich gehalten.In other words, the punch guide device is a linear guide device whose guide direction coincides with the punching direction. The play of the linear guide device is kept as low as possible in view of the precision to be achieved.
Die Führungsbolzen oder sonstigen Führungskörper der Linearführungseinrichtung können einstückiger Bestandteil des Stanzstempels sein, d.h. nahtlos aus dem gleichen Material dieser ausgebildet sein. Es wird aber bevorzugt, den oder die Führungskörper durch gesonderte mit dem Stempel fest verbundene, beispielsweise verlötete, verschweißte oder verschraubte Elemente auszubilden.The guide pins or other guide body of the linear guide device may be an integral part of the punch, i. be made of the same material seamlessly. However, it is preferred to form the guide body (s) by separate elements fixedly connected to the stamp, for example soldered, welded or screwed.

Das Stanzwerkzeug 1 weist ein Gestell 6 auf, zu dem eine Grundplatte 7 und eine Kopfplatte 8 gehören. Die Kopfplatte 8 ist bezüglich der Grundplatte 7 auf diese zu und von dieser weg in einer Stanzhubrichtung 9 bewegbar, die in
Von der Grundplatte 7 ragen vorzugsweise (aber nicht zwingend) Führungssäulen 12, 13, 14, 15 (siehe auch
Die Grundplatte 7 trägt eine Schnittplatte 16 (
Die Schnittplatten 18, 19 weisen außerdem Stanzöffnungen 21, 22 auf, deren Kontur der gewünschten Stanzkontur folgt. In der Ausführungsform nach
Den Stanzöffnungen 21, 22 sind Stanzstempel 23, 24 zugeordnet, die zum Beispiel aus

Die Stanzstempel 23, 24 sind an der Kopfplatte 8 schwimmend, d.h. seitlich beweglich gelagert, wie es nachfolgend anhand von
Der Stanzstempel 23 ist an zwei einander gegenüber liegenden Seiten 56, 57 in Gleitführungen 58, 59 gehalten. Zu diesen gehören Gleitstücke 30, 31, die durch die in Figur 5 dargestellten Bolzen 32, 33, 34, 35 fest mit der Kopfplatte 8 verschraubt werden. Die Gleitstücke 30, 31 weisen jeweils eine Führungsrippe 36, 37 auf. Die beiden Führungsrippen 36, 37 erstrecken sich parallel zueinander und weisen aufeinander zu. Sie sind in einem definierten Abstand zu der Kopfplatte 8 angeordnet und greifen in Nuten 38, 39, die in den Endflächen an den Seiten 56, 57 des Stanzstempels 22 ausgebildet sind. Die Rippen 36, 37 haben in den Nuten 38, 39 ein geringes Spiel. Dieses Spiel kann sowohl in X- wie auch in Y-Richtung vorgesehen sein. Außerdem sind die Rippen 36, 37 und die Nuten 38, 39 in ihrer Distanz zu der Kopfplatte so aufeinander abgestimmt, dass der Stanzstempel 23 mit seiner oberen, vorzugsweisen ebenen Druckfläche 40 an der Kopfplatte 8 anliegen kann, ohne von den Gleitstücken 30, 31 gegen die Kopfplatte 8 gespannt zu werden. Damit hat der Stanzstempel 23 eine Beweglichkeit in Querrichtung 41, die quer zu der Werkstücktransportrichtung 4 orientiert ist und zusätzlich eine Beweglichkeit in Werkstücktransportrichtung 4. Zur Verdeutlichung sind in
Die Gleitführungen 58, 59 können gegebenenfalls nicht nur ein Gleitbeweglichkeit in X-Richtung (Querrichtung 41), sondern, falls erwünscht auch eine Beweglichkeit in Y-Richtung (Werkstücktransportrichtung 4) erbringen. Die Gleitführungen 58,59 können aber auch so aufeinander und auf den Stanzstempel 23 abgestimmt sein, dass eine Gleitbeweglichkeit ausschließlich in einer gegebenen Richtung, z.B. der Querrichtung 41 gegeben ist.The sliding guides 58, 59 may optionally not only provide a sliding mobility in the X direction (transverse direction 41), but, if desired, also a mobility in the Y direction (workpiece transport direction 4). However, the sliding guides 58, 59 can also be matched to one another and to the
Zur Ausrichtung des Stanzstempels 23 in Bezug auf die Schnittplatte 18 ist mindestens eine Stempelführungseinrichtung 42 vorgesehen, die von einer Linearführung 43 oder auch gleich wirkenden Mitteln gebildet werden kann. Zu der Linearführung 43 gehören im vorliegenden Ausführungsbeispiel ein Führungskörper 44 und eine Führungsöffnung 45. Im vorliegenden Ausführungsbeispiel ist eine zweite Stempelführungseinrichtung 46 vorgesehen, die wiederum durch eine Linearführung gebildet wird und einen Führungskörper 47 sowie eine dazu passende Führungsöffnung 48 umfasst.For aligning the
In
Die im Beispiel im Querschnitt rechteckigen Führungskörper 44, 47 weisen jeweils mindestens zwei, vorzugsweise parallel zu der Werkstücktransportrichtung 4 (Y-Richtung) orientierte Führungsflächen auf. Diese Flächen liegen somit vorzugsweise in der Y-Z-Ebene. Entsprechende Führungsflächen sind in den Führungsöffnungen 45, 48 ausgebildet. Wie insbesondere
Die für die Bearbeitungsgenauigkeit wesentlichen Schneidkanten der Schnittplatte 18 sind im vorliegenden Ausführungsbeispiel, die parallel zu der Werkstücktransportrichtung 4 orientierten Kanten 49, 50, 51 der Stanzöffnung 21 (
Allgemein ausgedrückt ist die Stempelführungseinrichtung 42 und gegebenenfalls auch die Stempelführungseinrichtung 46 (falls vorhanden) jeweils so ausgebildet, dass sie den schwimmend gelagerten Stanzstempel quer zu derjenigen bzw. denjenigen Kanten der Stanzöffnung 21 präzise positioniert, an der bzw. denen die gewünschte Bearbeitungsgenauigkeit und ein sehr eng definierter Schneidspalt eingestellt werden sollen. Liegt die betreffende genauigkeitsbestimmende Schneidkante einer Stanzöffnung beispielsweise in der X-Y-Ebene schräg, dann ist der Stanzstempel 23 wiederum quer, vorzugsweise rechtwinklig, zu dieser Kante verschiebbar gelagert, wobei seine Position dann relativ zu der Schneidkante präzise durch die Stempelführungseinrichtung festgelegt wird.Generally speaking, the
Die Länge der Führungskörper 44, 47 ist so bemessen, dass sie weder beim Stanzhub, noch beim Rückhub aus den zugeordneten Führungsöffnungen 45, 48 heraus geraten, sondern vielmehr im ständigem Eingriff bleiben. Alternativ können die Führungskörper 44, 47, insbesondere wenn sie den Weg für ein Werkstück freigeben müssen, auch kürzer ausgebildet sein und aus den Führungsöffnungen 45, 48 auftauchen. Sie haben dann an ihrer Stirnseite Einführhilfen, beispielsweise in Form geeigneter Schrägflächen. Außerdem können die Führungskörper 44, 47, wie in den Figuren angedeutet, mit Schmiernuten versehen sein, die sich um den Umfang der Führungskörper 44, 47 herum erstrecken. Alternativ oder ergänzend können die Führungsöffnungen 45, 48 mit Schmiernuten versehen sein.The length of the
Das insoweit beschriebene Stanzwerkzeug 1 arbeitet wie folgt:
- Im Betrieb führt die
Kopfplatte 8 fortwährend eine auf und nieder gehende Bewegung inStanzhubrichtung 9 aus. Während des Abwärtshubswird das Stanzwerkzeug 1 synchron zu dem Werkstück 2 in Werkstücktransportrichtung 4 bewegt. 23, 24 tauchen inDie Stanzstempel die Schnittplatte 18, 19 ein und führen somit den gewünschten Stanzvorgang durch. Die 23, 24 quer zu den jeweils aktiven Schneidkanten, inPositionierung der Stanzstempel Figur 5 den Schneidkanten 49, 51 (und gegebenenfalls 50) wird 42, 46 unmittelbar bezogen auf die jeweilige Schnittplatte 18 (und entsprechend 19) übernommen. Etwaige Ungenauigkeiten dervon den Stempelführungseinrichtungen von den Säulen 12bis 15 ausgehenden Führung der Kopfplatte 8 haben keinen Einfluss auf die Genauigkeit des Stanzvorgangs. Es können somit Schneidspalte mit einer Genauigkeit eingestellt werden, die wesentlich höher ist als dievon dem Gestell 6 erbrachte Genauigkeit.
- In operation, the
top plate 8 continuously performs a rising and falling movement in punching 9. During the downward stroke, thepunching tool 1 is moved in synchronism with the workpiece 2 in the workpiece transporting direction 4. The 23, 24 dive into the cuttingpunches plate 18, 19 and thus perform the desired punching operation. The positioning of the 23, 24 transversely to the respective active cutting edges, inpunches FIG. 5 the cutting edges 49, 51 (and optionally 50) is taken over by the punch guide means 42, 46 directly related to the respective cutting plate 18 (and corresponding to 19). Any inaccuracies in the outgoing of thecolumns 12 to 15 guide thetop plate 8 have no effect on the accuracy of the punching process. Thus, cutting gaps can be set with an accuracy that is substantially higher than the accuracy provided by theframe 6.
Zum präzisen Ausrichten von Stanzstempeln in Bezug auf Schneidplatten ist der betreffende Stanzstempel 23 an der ihm zugeordneten Kopfplatte 8 schwimmend, also querbeweglich gelagert. Die Ausrichtung der Schneidkanten des Stanzstempels auf die Schneidkanten 49, 50, 51 der Schnittplatte 18 erfolgt durch mindestens eine Stempelführungseinrichtung 42, die unmittelbar zwischen dem Stanzstempel 23 und der Schnittplatte 18 wirkt und eine präzise Relativpositionierung quer zu den aktiven Schneidkanten bewirkt. Die Stempelführungseinrichtung 42 umfasst Zentrierelemente, deren Querschnitt zum Beispiel rechteckig, zylindrisch oder polygonal umgrenzt ist.For precise alignment of punches in relation to cutting plates of the punch in
Die Zentrierelemente können sich vom Stanzstempel 23 durch die Matrize bez. Schnittplatte 18 erstrecken. Alternativ können sich die Zentrierelemente von der Schnittplatte 18 durch Öffnungen des Stanzstempels 23 oder an Gleit- oder Positionierflächen desselben entlang erstrecken.The centering elements can from the
