Abstract

The method specified in Patent Application P 3840939.9-14 is to be improved according to the invention such that not all of the projections, especially narrow radii and sharp-edged profiles, are realised exclusively by a fluid-shaping method. The solution according to the invention consists in superimposing a mechanical deformation on the fluid-shaping method. The advantages obtained by the invention consist, in particular, in that even complicated shaped parts made of sheet metal can be produced in the final form in one working operation, i.e. even when, for example, narrow radii exist, subsequent shaping - in a further working station - is not necessary. Furthermore, an improvement in the product is to be noted, since all of the deformations occurring, whether in wide arcs or in narrow radii or in sharp-edged portions, can be optimally produced; all of the deformations are realised in one working step, each deformation being assigned the working method suitable for it. The less problematical deformations are formed by means of the fluid-shaping method, while narrow radii and the like are realised by additional, superimposed mechanical deformation. By proceeding in this way according to the invention, the deformation pressure for the fluid-shaping method can be reduced, which entails great advantages for the water hydraulics. In addition, the water pressure of the fluid-shaping process can perform a retaining function, which the ... Original abstract incomplete.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung von flachen Bauteilen, wobei mit einer einen Stößel aufweisenden Presse, welche eine aus einem Werkzeugoberteil und einem Werkzeugunterteil bestehende Form aufweist, ein Blech verformt wird, bei dem das Blech in die Form eingelegt und die Form durch den Stößel verschlossen wird, daß mit Hilfe von in dem Pressenrahmen geführten Keilen der Stößel verriegelt und gleichzeitig an dem zu verformenden Blech ein umlaufender Dichtring eingeformt und daß anschließend das Blech in der Form einem Hydroform-Verfahren unterworfen wird, wobei die durch den Hydroform-Arbeitsdruck am Werkzeug und der Presse wirksamen Kräfte mit Hilfe der Hydroform-Hydraulik kompensiert werden, nach Patentanmeldung P 38 40 939.9-14.The invention relates to a method for producing flat components, with a plunger having press, which one from one Tool upper part and a lower tool part existing Has shape, a sheet is deformed, in which the sheet inserted into the mold and the mold through the pestle is closed that with the help of in the press frame guided wedges of the plunger locked and at the same time a circumferential sealing ring on the sheet to be deformed molded in and then the sheet in the mold is subjected to a hydroforming process, the due to the hydroform working pressure on the tool and the Press effective forces with the help of hydroform hydraulics can be compensated, according to patent application P 38 40 939.9-14.

Weitere Überlegungen haben ergeben, daß es zweckmäßig sein kann, dem Hydroform-Verfahren es nicht allein zu überlassen, alle vorkommenden Radien und Profile zu verwirklichen. Das gilt vor allem für enge Radien und scharfkantige Profile in dem herzustellenden flachen Bauteil.Further considerations have shown that it is appropriate The hydroforming process may not be the only one leave to all occurring radii and profiles realize. This applies especially to tight radii and sharp-edged profiles in the flat to be produced Component.

Diese Aufgabe wird erfindungsgemäß bei einem Verfahren der eingangs näher bezeichneten Art dadurch gelöst, daß dem Hydroform-Verfahren eine mechanische Verformung überlagert wird.This object is achieved according to the invention in a method of the type specified at the outset in that the hydroform process a mechanical deformation is superimposed.

Die erfindungsgemäße zusätzliche mechanische Verformung kann gleichzeitig mit dem Hydroform-Verfahren ablaufen, sie kann aber auch, immer in der Hydroform-Station, nach oder vor dem Hydroform-Verfahren erfolgen. The additional mechanical deformation according to the invention can run simultaneously with the hydroforming process, but it can also, always in the hydroforming station or before the hydroforming process.  

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß auch komplizierte Formteile aus Blech in einem Arbeitsgang bis zur Endform gefertigt werden können, d.h. auch beim Vorliegen von z.B. engen Radien ist kein Nachformen - in einer weiteren Arbeitsstation - erforderlich. Darüber hinaus ist eine Verbesserung des Produkts zu verzeichnen, weil alle vorkommenden Verformungen, ob in weiten Bögen oder in engen Radien oder in scharfkantigen Abschnitten, optimal herstellbar sind; in einem Arbeitsschritt werden alle Verformungen verwirklicht, wobei jeder Verformung die ihr zukommende Arbeitsmethode zugeordnet wird. Die weniger problematischen Verformungen werden über das Hydroform- Verfahren aufgebracht, während enge Radien usw. durch zusätzliche, überlagerte mechanische Verformung realisiert werden. Wird in dieser Weise, gemäß der Erfindung gearbeitet, dann kann der Verformungsdruck für das Hydroform-Verfahren verringert werden, was große Vorteile für die Wasser-Hydraulik mit sich bringt. Außerdem kann der Wasserdruck des Hydroform-Prozesses eine Haltefunktion übernehmen, was das zu verformende Blech anbelangt.The advantages achieved by the invention are, in particular, that even complicated shaped parts made of sheet metal can be produced to the final shape in one operation, ie even if narrow radii are present, no post-forming - in a further work station - is required. In addition, there is an improvement in the product because all occurring deformations, whether in wide arches or in narrow radii or in sharp-edged sections, can be optimally produced; All deformations are carried out in one work step, with each deformation being assigned its working method. The less problematic deformations are applied using the hydroforming process, while tight radii etc. are achieved by additional, superimposed mechanical deformation. If this is done in accordance with the invention, the deformation pressure for the hydroforming process can be reduced, which has great advantages for the water hydraulics. In addition, the water pressure of the hydroforming process can take on a holding function with regard to the sheet to be deformed.

Gemäß der Hauptanmeldung erfolgt das Anbringen aller Ausbuchtungen bzw. Vertiefungen ausschließlich mit Hilfe des Hydroform-Verfahrens. Kommen enge Radien usw. vor, dann sind dabei sehr hohe Drücke in der Wasser- Hydraulik erforderlich, was erhebliche Nachteile hat. Enge Radien können natürlich auch durch Nachformen in einer separaten, der Hydroform-Station nachgeschalteten Arbeitsstation erfolgen. Diese Arbeitsweise ist umständlich und mit verhältnismäßig hohen Kosten verbunden. According to the main registration, everyone is attached Bulges or depressions only with the help of the hydroform process. There are tight radii etc. then there are very high pressures in the water Hydraulics required, which has considerable disadvantages. Narrow radii can, of course, also be formed in a separate, downstream of the hydroforming station Work station. This way of working is cumbersome and at a relatively high cost connected.  

Dagegen besteht die Erfindung im wesentlichen in einem kombinierten Verfahren, einem Verfahren mit einem Hydroform-Verfahren und einer diesem Prozeß überlagerten mechanischen Verformung.In contrast, the invention consists essentially in one combined procedure, one procedure with one Hydroform process and one of these processes superimposed mechanical deformation.

Die Zeichnung zeigt schematisch, ausgehend von Fig. 2 der Hauptanmeldung, eine Vorrichtung zum Durchführen des erfindungsgemäßen Verfahrens. In der Hauptanmeldung wurde schon das Hydroform-Verfahren beschrieben, das im wesentlichen darin besteht, daß über den Weg 9 Wasser hohen Druckes zugeführt wird, wodurch das Blech 10 in die Vertiefungen 51 der Matrize 15 gedrückt wird. Die Wirkungsrichtung des Wassers, aus dem Weg 9 kommend, ist mit den Pfeilen 52 angedeutet.The drawing schematically shows, starting from FIG. 2 of the main application, a device for carrying out the method according to the invention. In the main application, the hydroforming process has already been described, which essentially consists in that high pressure water is supplied via the path 9 , as a result of which the sheet 10 is pressed into the depressions 51 in the die 15 . The direction of action of the water, coming from path 9 , is indicated by arrows 52 .

Gemäß der Erfindung ist zusätzlich eine Mechanik vorgesehen, die beispielsweise aus weiteren Stößeln 53 bestehen kann. Mit Hilfe dieser Stößel 53 werden z.B. scharfkantige Profile 54 und sehr enge Radien 55 realisiert. Die Stößel 53 bewegen sich in Richtung der Doppelpfeile 56.According to the invention, a mechanism is additionally provided, which may consist of further plungers 53 , for example. With the aid of these plungers 53 , for example, sharp-edged profiles 54 and very narrow radii 55 are realized. The plungers 53 move in the direction of the double arrows 56 .

Mit Hilfe der dargestellten Anordnung kann beispielsweise so verfahren werden, daß in der aus der Hauptanmeldung bekannten Weise zuerst das Hydroform-Verfahren für problemlosere Vertiefungen abläuft, mit dem aus dem Hydroform-Verfahren vorhandenen Druck das Blech 10 an der Matrize 15 gehalten wird und danach der/die Stößel 53 betätigt werden, um scharfkantige Vertiefungen und beispielsweise enge Radien über diesen Weg herzustellen. Der dabei nötige Wasserdruck kann wesentlich geringer sein, als bei dem Verfahren nach der Hauptanmeldung.With the aid of the arrangement shown, it is possible, for example, to proceed in such a way that, in the manner known from the main application, the hydroforming process for trouble-free depressions first takes place, with the pressure from the hydroforming process the sheet 10 is held on the die 15 and then the / the plunger 53 are actuated to produce sharp-edged depressions and, for example, narrow radii in this way. The water pressure required can be much lower than in the procedure after the main application.
