Description
Die Erfindung betrifft ein Werkzeug zum Bearbeiten von Werkstücken, insbesondere Blechen, welche ein Oberwerkzeug mit einem Bearbeitungswerkzeug und ein Unterwerkzeug mit einem Gegenhalter aufweist, wobei das Oberwerkzeug und das Unterwerkzeug einander gegenüberliegend anordenbar sind, so dass der Gegenhalter auf der einen Seite und das Bearbeitungswerkzeug auf der anderen Seite eines dazwischen anordenbaren Werkstücks positioniert sind.The invention relates to a tool for machining workpieces, in particular sheets, which has an upper tool with a machining tool and a lower tool with a counter-holder, wherein the upper tool and the lower tool are arranged opposite each other, so that the counter-holder on one side and the machining tool on the other side of an intermediate work piece can be positioned.

Zum Bearbeiten der Werkstücke mit den vorgenannten Werkzeugen werden diese zwischen dem Ober- und Unterwerkzeug verfahren, wobei das Ober- und Unterwerkzeug auf das Werkstück zugeführt sind und anliegen, so dass einerseits die Kugel auf der einen Seite des Werkstücks anliegt und gegenüberliegend das Bearbeitungswerkzeug an dem Werkstück angreift und mit Druck gegen die gegenüberliegende Kugel arbeitet. Dabei können auf der der Kugel zugwandten Seite des Werkstücks an der Oberfläche Kratzer, Abdrücke oder Eindellungen entstehen, welche die Qualität des Werkstücks beeinträchtigen.To edit the workpieces with the aforementioned tools they are moved between the upper and lower tool, the upper and lower tool are fed to the workpiece and rest, so that on the one hand the ball rests on one side of the workpiece and the machining tool on the opposite Workpiece attacks and works with pressure against the opposite ball. In this case, on the ball zugwandten side of the workpiece on the surface scratches, impressions or dents arise, which affect the quality of the workpiece.
Der Erfindung liegt die Aufgabe zugrunde, ein Werkzeug zum Bearbeiten von Werkstücken, insbesondere Blechen, vorzuschlagen, bei dem eine Beschädigung der Werkstückoberfläche des zu bearbeitenden Werkstücks ausbleibt, an welcher ein Gegenhalter des Werkzeugs angreift. Diese Aufgabe wird durch einen als Kugel ausgebildeten Gegenhalter gelöst, welcher zumindest eine äußere Randzone mit einer geringeren Oberflächenhärte als das zu bearbeitende Werkstück oder die zu bearbeitende Werkstückoberfläche aufweist. Dadurch wird der als Kugel ausgebildete Gegenhalter weicher als das zu bearbeitende Werkstück bzw. die zu bearbeitende Werkstückoberfläche ausgebildet, wodurch es trotz der Anpresskraft zwischen dem Oberwerkzeug und dem Unterwerkzeug weder zu Eindrücken an oder in die Werkstückoberfläche des Werkstücks kommt, noch Kratzer auf der Oberfläche des Werkstücks gebildet werden. Dadurch kann die Bearbeitungsqualität solcher Werkstücke erhöht werden.The invention has for its object to provide a tool for machining workpieces, in particular sheets, in which there is no damage to the workpiece surface of the workpiece to be machined, which acts on a counter-holder of the tool. This object is achieved by a counter-holder embodied as a ball, which has at least one outer edge zone with a lower surface hardness than the workpiece to be machined or the workpiece surface to be machined. As a result, the counter-holder embodied as a ball is softer than the workpiece to be machined or the workpiece surface to be machined, whereby, despite the contact force between the upper tool and the lower tool, neither impressions on nor in the workpiece surface of the workpiece, nor scratches on the surface of the workpiece Workpiece are formed. As a result, the processing quality of such workpieces can be increased.
Nach einer bevorzugten Ausführungsform der Erfindung ist die äußere Randzone der Kugel als Beschichtung ausgebildet, welche auf einem Kern aufgebracht ist. Dadurch kann zum einen eine einfache Herstellung eines solchen Gegenhalters erfolgen. Zum anderen kann diese Beschichtung auch als Verschleißindikator eingesetzt werden. Sobald diese Beschichtung Schädigungen, Abplatzungen oder Durchbrechungen aufweist, kann eine Abnutzung des Gegenhalters erkannt und ein Austausch durchgeführt werden.According to a preferred embodiment of the invention, the outer edge zone of the ball is formed as a coating, which is applied to a core. This can be done on the one hand, a simple production of such a counter-holder. On the other hand, this coating can also be used as a wear indicator. Once this coating has damage, flaking or perforations, wear of the counter-holder can be detected and replaced.
Alternativ kann die äußere Randzone auch durch eine Ummantelung ausgebildet werden, welche auf dem innenliegenden Kern aufgebracht ist. Eine solche Ummantelung ist zumeist deutlich dicker als eine Beschichtung ausgebildet. Dadurch steht auch eine größere Auswahl an verschiedenen Materialien zur Verfügung, die eine solche Ummantelung bilden können. Dies ermöglicht auch den Einsatz von verschiedenen Herstellungsverfahren. Beispielsweise kann die Ummantelung sowohl durch ein Aufvulkanisieren als auch durch weitere Polymerisationsverfahren hergestellt werden. Eine solche Ummantelung kann, wie auch die Beschichtung, einen Verschleißindikator bilden. Der Kern der Kugel kann aus einem härteren Material als die Beschichtung oder Ummantelung ausgebildet sein.Alternatively, the outer edge zone can also be formed by a sheath which is applied to the inner core. Such a sheath is usually much thicker than a coating formed. This also provides a wider choice of different materials that can form such a sheath. This also allows the use of different manufacturing processes. For example, the sheath can be produced both by vulcanization and by further polymerization. Such a sheath can, like the coating, form a wear indicator. The core of the ball may be formed of a harder material than the coating or sheath.
Eine alternative Ausführungsform der Erfindung sieht vor, dass die Kugel aus einem Vollmaterial ausgebildet ist, deren Oberflächenhärte geringer als die des zu bearbeitenden Werkstücks ist. Dies ermöglicht eine kostengünstige Herstellung solcher Gegenhalter.An alternative embodiment of the invention provides that the ball is formed of a solid material whose surface hardness is lower than that of the workpiece to be machined. This allows a cost-effective production of such an anvil.
Bevorzugt ist die zumindest äußere Randzone der Kugel oder die Kugel selbst aus einem Duroplasten, aus einem Thermoplasten, aus einem thermoplastischen Elastomer oder einem Elastomer, aus einem Kunstfaserwerkstoff, aus einem Buntmetall, oder aus einem elastischen Naturprodukt, wie z.B. einer Naturfaser, Filz, Kork, Fell, Leder, hergestellt. Diese Materialien eignen sich insbesondere zur Vermeidung von Kratzern an der Oberfläche und Einbringung von Deformationen. Gleichzeitig kann eine kostengünstige Herstellung erfolgen. Ebenso können für die äußere Randzone oder eine aus Vollmaterial bestehende Kugel Buntmetalle, wie beispielsweise Messing oder dergleichen, eingesetzt werden, welche beispielsweise weicher sind als die zumeist aus Stahl bestehenden Werkstücke.Preferably, the at least outer edge zone of the ball or the ball itself is made of a thermoset, a thermoplastic, a thermoplastic elastomer or an elastomer, a synthetic fiber material, a non-ferrous metal, or a resilient natural product, such as e.g. a natural fiber, felt, cork, fur, leather, made. These materials are particularly suitable for preventing scratches on the surface and introducing deformations. At the same time, a cost-effective production can take place. Likewise, non-ferrous metals, such as brass or the like, can be used for the outer edge zone or a ball made of solid material, which are, for example, softer than the mostly made of steel workpieces.
Des Weiteren kann auf die äußere Randzone der Kugel eine Beschichtung aufgebracht sein. Dies kann beispielsweise eine Farb- oder Lackschicht sein. Eine solche zusätzlich aufgebrachte Farb- oder Lackschicht dient als Verschleißindikator, um bei auftretenden Verschleißerscheinungen rechtzeitig einen Austausch des Gegenhalters zu ermöglichen.Furthermore, a coating can be applied to the outer edge zone of the ball. This can be, for example, a paint or varnish layer. Such an additionally applied paint or varnish layer serves as a wear indicator in order to enable a timely replacement of the counter-holder if signs of wear occur.
Eine alternative Ausgestaltung des Gegenhalters sieht vor, dass die äußere Randzone aus zwei oder mehreren Schichten mit voneinander abweichenden Materialeigenschaften besteht, wobei die äußere Schicht verschleißfester als die innere Schicht ausgebildet ist, jedoch die äußere Schicht eine geringere Oberflächenhärte als das zu bearbeitende Werkstück oder die zu bearbeitende Werkstückoberfläche aufweist. Dadurch kann die äußere Randzone gegenüber dem Kern der Kugel nachgiebig sein, jedoch noch ein erhöhtes Verschleißpotenzial aufweisen, ohne jedoch die Werkstückoberfläche zu beeinträchtigen.An alternative embodiment of the counter-holder provides that the outer edge zone consists of two or more layers with divergent material properties, wherein the outer layer is more resistant to wear than the inner layer, but the outer layer has a lower surface hardness than the workpiece to be machined or having machined workpiece surface. As a result, the outer edge zone may be yielding to the core of the ball, but still have an increased wear potential, but without affecting the workpiece surface.
Der Gegenhalter kann in einer Aufnahme des Unterwerkzeugs angeordnet sein, welche zum Werkstück weisend offen ausgebildet ist, wobei der Gegenhalter mit einer Halteeinrichtung zur Positionierung des Gegenhalters in der Aufnahme angeordnet ist, durch welche der Gegenhalter entlang einer Längsachse des Unterwerkzeugs in der Aufnahme nachgiebig aufgenommen ist. Dies ermöglicht eine Nachgiebigkeit des Gegenhalters in einem vorgegebenen Toleranzbereich während der Bearbeitung des Werkstücks, um eine Überbelastung auf die Werkstückoberfläche zu vermeiden.The counter-holder can be arranged in a receptacle of the lower tool, which is open towards the workpiece, wherein the counter-holder is arranged with a holding device for positioning the counter-holder in the receptacle, by which the counter-holder is resiliently received along a longitudinal axis of the lower tool in the receptacle , This allows a compliance of the counter-holder in a predetermined tolerance range during the machining of the workpiece in order to avoid an overload on the workpiece surface.
Die Haltevorrichtung kann als Federelement ausgebildet sein, welches einen Aufnahmeabschnitt zur Anordnung des Gegenhalters sowie Befestigungsabschnitte zur Fixierung des Federelementes an der Aufnahme des Unterwerkzeuges aufweist und dazwischenliegend streifenförmig Dehnabschnitte umfasst. Durch ein solches Federelement wird konstruktiv in einfacher Weise eine Positionierung des Gegenhalters zum Unterwerkzeug ermöglicht. Gleichzeitig kann durch die streifenförmigen Dehnabschnitte der Haltevorrichtung in einfacher Weise die Nachgiebigkeit des Gegenhalters relativ zum Unterwerkzeug eingestellt werden.The holding device may be formed as a spring element which has a receiving portion for the arrangement of the counter-holder and fastening portions for fixing the spring element to the receptacle of the lower tool and comprises strip-shaped expansion portions in between. By such a spring element is structurally in a simple manner allows positioning of the counter-holder to the lower tool. At the same time can be adjusted relative to the lower tool by the strip-shaped Dehnabschnitte the holding device in a simple manner, the compliance of the counter-holder.
Eine weitere bevorzugte Ausgestaltung der Halteeinrichtung sieht vor, dass bei einer Überbelastung des Unterwerkzeugs der Gegenhalter vollständig gegenüber einem äußeren Rand der Aufnahme in die Aufnahme eintaucht und die Dehnabschnitte der Halteeinrichtung plastisch verformt sind. Somit dient die Haltevorrichtung als Überlastschutz und gleichzeitig als Indikator für eine Überlast, welche beispielsweise durch Unebenheiten des Blechs, falsche Bearbeitungsparameter, Kollisionen, Blechschwingungen oder Fehlbedienungen ausgelöst sein können.A further preferred embodiment of the holding device provides that when an overload of the lower tool, the counter-holder completely immersed in the receptacle with respect to an outer edge of the receptacle and the Dehnabschnitte the holding device are plastically deformed. Thus, the holding device serves as overload protection and at the same time as an indicator of an overload, which may be triggered for example by unevenness of the sheet, wrong processing parameters, collisions, sheet metal vibrations or incorrect operation.
