Abstract

Device for shaping a preferably flat or plate-shaped workpiece wih two robot units for automatic guiding a shaping tool simultaneously along each side of the workpiece.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Umformen von Werkstücken, wie tafelförmigen Platten, dünnem Blech, stabförmigen Materialien, Rohre, o.dgl., aus Metall, Kunststoff und anderen umformfähigen Materialien.The The present invention relates to an apparatus and a method for forming workpieces, like tabular Plates, thin Sheet metal, rod-shaped Materials, pipes, or the like, of metal, plastic and other formable materials.

Stand der Technik sind Umformverfahren mit und ohne Gegenform (Matrize).was standing The technique is forming processes with and without counterform (die).

Zu den Umformverfahren ohne Matrize gehört das inkrementelle Umformen, wie in der DE 103 17 880 B3 dargestellt. Dieses Verfahren stößt aber bei verschiedenen Umformgeometrien an seine Grenzen. So ist es z.B. schwer oder gar unmöglich senkrechte Vertiefungen, Kanten o.dgl. herzustellen oder Erhöhungen und Vertiefungen an einem Werkstück zu realisieren.Forming processes without a die include incremental forming, as in the DE 103 17 880 B3 shown. However, this method reaches its limits with different forming geometries. For example, it is difficult or even impossible vertical recesses, edges or the like. produce or elevations and depressions on a workpiece to realize.

Bei Umformverfahren mit Matrize wird eine kostenintensive Matrize für das Werkstück angefertigt.at Forming process with die is a costly die for the workpiece made.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung und ein Verfahren zum Umformen von Werkstücken anzugeben, die ein kostengünstiges Umformen ohne formgebundene Matrize ermöglichen, wobei trotzdem eine Vielzahl von Umformgeometrien erreichbar sind.task It is the object of the present invention to provide an apparatus and a method for forming workpieces indicate that a cost effective Allow forming without a molded matrix, while still a Variety of forming geometries are achievable.

Die obige Aufgabe wird insbesondere durch eine Vorrichtung gemäß Anspruch 1 oder ein Verfahren gemäß Anspruch 4 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The The above object is achieved in particular by a device according to claim 1 or a method according to claim 4 solved. Advantageous developments are the subject of the dependent claims.

Die hier vorgestellte Bearbeitungsvorrichtung zeigt ein Umformverfahren, bei dem mindestens zwei Handhabungseinheiten jeweils ein Bearbeitungswerkzeug, ein Gegenwerkzeug, eine Werkstückhalterung oder eine Niederhaltung geführt bewegen. Insbesondere führt jede Handhabungseinheit jeweils ein Bearbeitungswerkzeug derart, daß das vorzugsweise plattenförmige oder flache Werkstück koordiniert von entgegengesetzten Seiten berabeitet wird. Optional ist die Einspannung bzw. Niederhaltung ungeführt oder passiv.The here presented processing device shows a forming process, in each case a machining tool in the case of the at least two handling units, a counter tool, a workpiece holder or a holddown move. In particular, leads each handling unit each a machining tool so, that preferably disc-shaped or flat workpiece coordinated from opposite sides. Optional is the clamping or hold down unguided or passive.

Als Handhabungseinheiten sind insbesondere Industrieroboter, Portalroboter, CNC-Maschinen, die steuerungstechnisch miteinander gekoppelt sind und gemeinsam ein Werkstück bearbeiten, o.dgl. vorgesehen.When Handling units are in particular industrial robots, gantry robots, CNC machines that Control technology coupled with each other and together workpiece edit, or the like. intended.

Die Bearbeitung erfolgt durch zwei Handhabungs- bzw. Bearbeitungseinheiten, die jeweils mit einem eigenen formungebundenen Bearbeitungswerkzeug ausgerüstet sind, welches die aktive bearbeitende impulsgebende Rolle (schlagend, drückend, pressend, rotierend, strahlausendend) sowie auch die passive Rolle als Gegenstück (Widerlager, Matrize, Pressform, Amboss) übernehmen kann.The Processing is carried out by two handling or processing units, each with its own form-free machining tool equipped are the active working impulsive role (striking, oppressive, pressing, rotating, jet-milling) as well as the passive role as a counterpart (Abutment, die, die, anvil) can take over.

Je nach Bearbeitungsrichtung wechseln sich die Bearbeitungseinheiten mit ihrem Werkzeug in der passiven und aktiven Bearbeitung ab. Es ist auch eine gleichzeitige aktive bzw. passive Rolle möglich.ever The machining units change according to the machining direction with their tool in passive and active editing. It is also a simultaneous active or passive role possible.

Nachfolgend wird die Erfindung anhand der Zeichnung erläutert. Es zeigt:following the invention will be explained with reference to the drawing. It shows:

1 Bearbeitungseinheit 1 passiv
Gegenhaltend
Bearbeitungseinheit 2 aktiv

Das formungebundene Bearbeitungswerkzeug besteht beispielsweise aus einem Kugelkopf, der an einem Schlagwerkzeug eingespannt ist. Es ist auch ein Kopf möglich. der durch Anpressdruck die Umformung vornimmt, dieser kann auch rotierend ausgeführt sein.The Shaped machining tool consists, for example a ball head, which is clamped on a striking tool. It is also a head possible. which makes the deformation by contact pressure, this can also rotating executed be.

In den Werkzeugkopf können z.B. Strahlkanäle eingearbeitet sein, um damit auch Laserstrahlen, Kugelstrahlen, Wasserstahlen usw. zur Umformung einzusetzen.In the tool head can e.g. beam channels be incorporated, so that also laser beams, shot peening, Use water steel etc. for forming.

Kombinationen aus den Bearbeitungsarten (schlagend, rotierend, usw.) können auch zum Einsatz kommen.combinations from the processing types (hitting, rotating, etc.) can also be used.

Die Bearbeitungsvorrichtung kann noch durch weitere Handhabungseinheiten sowie Zusatzachsen, Lineareinheiten oder Dreheinheiten ergänzt werden.The Processing device can still by further handling units and additional axes, linear units or rotary units are added.

Bei sehr komplizierten und großen Formen bzw. Werkstücken kann zur besseren Bearbeitung die Werkstückhalterung bzw. Niederhaltung über weitere Handhabungseinheiten flexibel geführt werden.at very complicated and big Shapes or workpieces can for better editing the workpiece holder or hold down on more Handling units are guided flexibly.

Der Vorteil dieser Umformeinrichtung besteht in dem formungebundenen Werkzeug und in der wechselseitigen und/oder koordinierten, vorzugsweise automatisierten Bearbeitung des Werkstücks, ohne daß die Herstellung einer spezifischen Form erforderlich ist. Insbesondere können durch das gleichzeitige oder abwechselnde Bearbeiten von entgegengesetzten Seiten auch schwierige Umformgeometrien, wie senkrechte Vertiefungen, Kanten, sowohl Erhöhungen als auch Vertiefungen u.dgl., an einem Werkstück realisiert werden.The advantage of this forming device consists in the non-forming tool and in the mutual and / or coordinated, preferably automated processing of the workpiece, without the production of a specific form he is necessary. In particular, the simultaneous or alternating processing of opposite sides can also realize difficult forming geometries, such as vertical depressions, edges, both elevations and depressions and the like, on a workpiece.

Vorzugsweise kann die Bearbeitung grundsätzlich wie in der DE 103 17 880 B3 beschrieben, erfolgen.Preferably, the processing can basically as in the DE 103 17 880 B3 described, done.
