Die Erfindung betrifft eine Verwendung des Siebdruckverfahrens und eine Einrichtung zum örtlich gezielten Auftragen von Gleitmittel auf Tiefziehbleche. The invention relates to a use of the screen printing process and a device for the locally targeted application of lubricant to deep-drawn sheets. Bei der Umformung von Blechen in Umformmaschinen wird zur Minderung der Reibung zwischen Umformgut und Werkzeug ein Gleitmittel eingesetzt. When forming sheet metal in forming machines, there is a reduction A lubricant is used to reduce the friction between the material to be formed and the tool. Dieses Gleitmittel kann in fester Form, pastös oder flüssig vorgegeben werden.This lubricant can be given in solid, pasty or liquid form will. Zur Einsparung von Gleitmittel oder bei der Notwendigkeit, örtlich aus umformtechnischen Gründen hohe Reibungswerte zu erzielen, wird das Umformgut nur teilweise und örtlich gezielt mit Gleitmittel versehen. So werden bei der Blechumformung in Umformmaschinen möglichst nur wenige Stellen mit Gleitmittel beschichtet. Es ist bekannt das Gleitmittel mittels Walzen, Sprühdüsen, getränkten Schaumstoff oder - manuell - mit einem Pinsel aufzutragen. Wenn das Umformgut außerhalb des Werkzeuges der Umformmaschine mit Gleitmittel versehen wird, muß dieses noch in das Werkzeug zur Umformung eingelegt werden. Dies geschieht manuell oder mit einem umformmaschinenabhängigen Einlegegerät oder mittels eines Positionierers, der über Daten-oder End- bzw. Winkelgeber gesteuert wird. To save on lubricant or, if necessary, locally To achieve high coefficients of friction for reasons of forming technology, the material to be formed only partially and locally provided with specific lubricant. This is what happens in sheet metal forming In forming machines, only a few places as possible are coated with lubricant. It is known the lubricant by means of rollers, spray nozzles, soaked foam or - applied manually - with a brush. If the material to be formed is outside the tool the forming machine is provided with lubricant, this must still be in the tool are inserted for forming. This is done manually or with a forming machine-dependent Insertion device or by means of a positioner, which via data or end or angle encoder is controlled. Das Auftragen des Gleitmittels mit einem Pinsel oder einer Sprühdose erfordert eine zusätzliche Arbeitskraft, ist ungenau und nicht schnell genug, während ein örtlich gezieltes Aufbringen des Gleitmittels mit getränktem Schaumstoff, z. B. in einer speziellen Anlage, praktisch nur über einen aufwendigen Roboter mit einer aufwendigen Steuerung möglich und deshalb teuer ist. Applying the lubricant with a brush or a spray can requires additional labor, is inaccurate and not fast enough while a locally targeted application of the lubricant with soaked foam, e.g. B. in a special system, practically only with a complex robot a complex control possible and is therefore expensive. Das aufgetragene Gleitmittel muß vor dem Lackieren des Umformgutes wieder entfernt werden. Zuviel aufgetragenes Gleitmittel erhöht daher Entfettungskosten.The applied lubricant must be applied before painting the material to be formed be removed again. Too much lubricant applied therefore increases degreasing costs. Aufgabe der Erfindung ist es, Gleitmittel zwar örtlich möglichst genau und gleichmäßig stark aber dennoch mit apparativ einfachen Mitteln auf Tiefziehbleche aufzutragen. Diese Aufgabe wird durch die Anwendung des Siebdruckverfahrens für diese Zwecke gelöst. The object of the invention is to provide lubricants locally as possible accurate and evenly strong but nonetheless with simple equipment on deep-drawn sheets to apply. This task is accomplished by using the screen printing process for solved these purposes. Dadurch ist es möglich, sämtliche Arten von Gleitmittel einzusetzen, wobei ein örtliches gleichmäßiges Auftragen verwirklicht wird. Dies konnte bisher nur durch Walzen erzielt werden, welche das gesamte Umformgut beschichteten. Durch gezieltes Auftragen von Gleitmittel mit einer Siebdruckvorrichtung in vorbestimmter gleichmäßiger Dicke, wird Gleitmittel eingespart. Die Einrichtung arbeitet kontinuierlich und wird zweckmäßigerweise mit der Umformgut-Zuführung zur Umformmaschine gekoppelt. This makes it possible to use all types of lubricants, a local even application is realized. So far this has been possible can only be achieved by rolling, which coated the entire material to be formed. By targeted application of lubricant with a screen printing device in a predetermined uniform thickness, lubricant is saved. The facility works continuously and is expediently coupled with the feed to the forming material to the forming machine. In vorteilhafter Ausgestaltung der Erfindung kann die Siebdruckvorrichtung gebildet sein durch wenigstens ein umlaufendes teilmaskiertes Endlos-Siebband, an dessen vorzugsweise horizontaler Auftragsstrecke das Tiefziehblech außenseitig entlangführbar ist, wobei im Inneren der Siebbandschlaufe im Bereich der Auftragsstrecke die Gleitmittelzufuhr und eine Abstreif- oder Rakelvorrichtung vorgesehen sind. Durch kontinuierliches Auftragen von Gleitmittel kann nach Bedarf eine höhere Bandgeschwindigkeit eingestellt werden. Durch entsprechende leicht herstellbare, rasch auswechselbare und problemfrei stapelbare Siebbandschlaufen läßt sich für jedes Teil ein spezifisches Auftragsbild für das Gleitmittel verwirklichen. Die Gleitmittelmenge je Flächeneinheit beschichteter Oberfläche läßt sich durch Auswahl der Siebstärke und/oder der Maschenweite bestimmen. In an advantageous embodiment of the invention, the screen printing device be formed by at least one circulating, partially masked, endless screen belt whose preferably horizontal application path can be guided along the deep-drawn sheet on the outside is, with the lubricant supply inside the sieve belt loop in the area of the application path and a wiping or squeegee device are provided. Through continuous Applying lubricant can be set to a higher belt speed as required will. Due to the fact that they are easy to manufacture, quickly replaceable and problem-free stackable sieve belt loops, a specific order pattern can be created for each part realize for the lubricant. The amount of lubricant per unit area coated The surface can be determined by selecting the screen thickness and / or the mesh size. Ferner können gegenüberliegend zwei umlaufende teilmaskierte Endlos-Siebbänder angeordnet werden, wenn z. B. auch die Unterseite des Umformgutes örtlich gezielt mit Gleitmittel versehen werden soll. Furthermore, two circumferential, partially masked, endless sieve belts can be positioned opposite one another be arranged if z. B. also the underside of the material to be formed locally targeted should be provided with lubricant. Schließlich kann vor der Siebdruckvorrichtung wenigstens ein mit gleicher Arbeitsgeschwindigkeit umlaufendes Einzugswalzenpaar vorgesehen sein. Finally, in front of the screen printing device, at least one with the same working speed rotating feed roller pair can be provided. Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles soll die Erfindung näher erläutert werden. Es zeigt Fig 1 eine schematisch dargestellte Siebdruckvorrichtung zum Auftragen von Gleitmittel gemäß der Erfindung, F i g. 2 eine Draufsicht auf ein mit Gleitmittel versehenes Umformgut, F i g. 3 Aufstreichen des Gleitmittels durch einen Rakel, F i g. 4 eine Anordnung zum Aufbringen von flüssigem Gleitmittel. Based on an embodiment shown in the drawing the invention is to be explained in more detail. 1 shows a schematically represented Screen printing device for applying lubricant according to the invention, FIG. 2 a plan view of a material to be formed provided with lubricant, FIG. 3 spread of the lubricant through a doctor blade, FIG. 4 shows an arrangement for applying liquid Lubricant. Wie aus F i g. 1 zu ersehen ist, besteht die Siebdruckvorrichtung zum doppelseitigen Auftragen von Gleitmittel aus zwei umlaufenden, über Führungs-Walzen 1,2 und 3, 4 geführte Endlos-Siebbänder 5 und 6, welche bekannterweise Durchlaßflächen 7 und verschlossene Flächen 8 aufweisen. Zum Einziehen von Umformgut 9 sind Einzugswalzen 10 vorgesehen. Führungswalzen 1-4 und Einzugswalzen 10 werden durch ein nichtgezeichnetes Getriebe angetrieben, so daß alle Walzen gleiche Umfangsgeschwindigkeiten haben. Das Gleitmittel 11 wird an den Innenseiten 12 auf die Endlos-Siebbänder 5, 6 aufgebracht. Durch ein Rakel-oder Abstreifsystem 13 wird das Gleitmittel 11 in gleichmäßiger Dicke über das Endlossiebband verteilt, d. h. zu dick aufgebrachtes Gleitmittel 11 wird abgestreift. Je nach Fadendichte und Materialstärke des Siebbandgewebes läßt sich die gewünschte Auftragsmenge des Gleitmittels 11 leicht einhalten. As shown in FIG. 1, there is the screen printing device for double-sided application of lubricant from two rotating guide rollers 1, 2 and 3, 4 guided endless screen belts 5 and 6, which are known to have passage areas 7 and 8 closed surfaces. Feed rollers are used for drawing in the material to be formed 9 10 provided. Guide rollers 1-4 and feed rollers 10 are indicated by a not shown Gear driven so that all rollers have the same peripheral speeds. The lubricant 11 is applied to the inner sides 12 of the endless screen belts 5, 6. By means of a doctor blade or wiper system 13, the lubricant 11 becomes more uniform Thickness distributed over the endless screen belt, d. H. Lubricant applied too thickly 11 is stripped off. Depending on the thread density and material thickness of the belt mesh the desired application amount of the lubricant 11 can easily be adhered to.
