Verfahren und Anordnung zum Verbinden von Metallblechen miteinander durch Sprengverschweissung. Method and arrangement for joining metal sheets to one another by explosive welding.
■ Die Erfindung bezieht sich auf ein Verfahren zum Verbinden von Metallblechen miteinander durch son. Spranrcverschweissung, was bedeutet, dass auf der Aussenseite wenigstens des einen Bleches eine Schicht eines Sprengstoffes angebracht wird, bei dessen Detonation ein so starker Druck oder Stoss zwischen den Blechen erzeugt wird, dass diese metallisch miteinander verbunden werden. Dieses Verfahren wird z.3. in der schwedischen Patentschrift 183.172 beschrieben. Andererseits ist es bekannt einen Sprengstoff, wie Pentaerythritol-Tetranitrat (PETN) in einem Träger aus einem porigen Werkstoff mit offenen Zellen, wie SchaumkuBStstoff, zu verteilen. Der Sprengstoff ist dabei in den Poren in der Form von Kristallen niedergeschlagen, und die Menge je Volumeneinheit des Trägers ist klein.The invention relates to a method of connecting of metal sheets together by son. Spranrc welding, which means that a layer of an explosive is attached to the outside of at least one sheet metal Detonation, such a strong pressure or impact is generated between the sheets that they are metallically connected to one another. This procedure is z.3. described in Swedish patent specification 183,172. On the other hand it is known to be an explosive such as pentaerythritol tetranitrate (PETN) in a carrier made of a porous material with open cells, such as foam plastic to distribute. The explosive is deposited in the pores in the form of crystals, and the amount per unit volume of the Carrier is small.
Gemäss der Erfindung wird ein solcher Träger für die Verbindung von dünnen Metallblechen benutzt, was im wesentlichen dadurch erzielt wird, dass auf das eine Blech eine Scheibe einer porigen Masse mit offenen Zellen, wie aus Schaumkunststoff, aufgebracht wird, in der Teilchen eines Sprengstoffes verteilt sind und dieser Form zur Detonation gebracht werden. Da die Dichte des Sprengstoffes, gerechnet auf die Volumeneinheit, klein ist, wird vermieden, dass die von der Explosionswelle getroffene Metalloberfläche beschädigt oder verformt wird, auch wenn das Blech dünn ist und aus so weichem Merkstoff, wie z.B. Aluminium besteht.According to the invention, such a carrier for Connection of thin metal sheets used, which is achieved essentially by the fact that on one sheet a disc of a porous mass with open cells, such as foam plastic, applied in which particles of an explosive are distributed and detonated in this form. Because the density of the explosive is small in terms of volume, the metal surface hit by the explosion wave is avoided is damaged or deformed, even if the sheet metal is thin and made of such a soft material as e.g. aluminum.

Eine für die Lurchführung des Verfahrens besonders neeipnete Ausführunpsform zeichnet sich dadurch aus, dass die Scheibe auf ihrer einen Seite mit den einen Metallblech zu einer verkaufsfertio-en Einheit verbunden ist.A particularly suitable form of execution for carrying out the procedure is characterized by the fact that one side of the disc is ready for sale with one sheet of metal Unit is connected.
Die Erfindung soll nachstehend unter 3ezurnahne auf eine in der anliegenden Zeichnung schaubildlich darrestellte Ausf'ihrun<r näher beschrieben werden.The invention is intended below under 3ezurnahne on a Execution shown diagrammatically in the attached drawing are described in more detail.
In der Zeichnung ist 10 eine Matte oder Scheibe aus Schaumkunststoff, wie Polyethylen, mit niedrigen Volumenpewicht;In the drawing, 10 is a mat or disk made of foamed plastic, such as polyethylene, of low volume weight;
z.B. 10-40 g/dm , In dieser Scheibe sind Kristalle von PETf! niedergeschlagen, wie weiter unten näher beschrieben werden wird. Ein dünnes Blech 12 eines Metalls, wie Aluminium, ist mi<t der Scheibe 10 zu einer verkaufsfertiren Einheit fest verbunden. Das Blech 12 kann eine Stärke von der einer Folie bis zu 5 mm haben. Auf ihrer anderen Flachseite ist die Scheibe 10 zweckmässi^ mit einer versteifenden Schicht oder Platte 14 aus z.3. hartem Fasermaterial, überdeckt, die zur Aufrabe hat, bei Beförderung: und ähnlichen Belastungen zu verhindern, dass das dünne blech verbogen oder in anderer Weise verformt wird. Die Verbindung zwischen den Teilen 10, 12, 14 läsfit sich mit Hilfe eines Klebstoffes an sich bekannter Art erzielen.e.g. 10-40 g / dm, in this disc there are crystals of PETf! dejected, as will be described further below. A thin sheet 12 of a metal, such as aluminum, is the middle Disk 10 firmly connected to form a unit ready for sale. The sheet metal 12 can have a thickness of a foil up to 5 mm to have. On its other flat side, the disk 10 is expedient with a stiffening layer or plate 14 from z.3. hard Fiber material, covered, which has to be picked up during transport: and similar loads to prevent the thin sheet from being bent or otherwise deformed. The connection between the parts 10, 12, 14 läsfit with the help of an adhesive achieve a known type.
Die Schaumstoffscheibe 10 hat offene Zellen, deren Wände nachgiebig sind, so dass sich die Scheibe wie ein Schwamm zusammendrücken lässt, um danach ihr ursprüngliches Volumen und ihre ursprüngliche Form wieder einzunehmen.The foam disk 10 has open cells, the walls of which are flexible, so that the disc can be squeezed like a sponge to restore its original volume and to return to its original shape.
Sprengstoff in der Form von unphlegmatisiertem, getrocknetem PETN wird in Aceton zu einer Konzentration von z.B. 15 % des Sprengstoffes gelöst. Die Schaumstoffscheiben werden dann in die Lösung eingetaucht und danach in kaltes Wasser, was zur Folge hat, dass sich der Sprengstoff auf den Wänden der Schaumstoffporen in Kristallform wiederschlägt, weil er in Wasser unlöslig ist.Explosives in the form of unphlegmatized, dried PETN is in acetone to a concentration of e.g. 15% of the explosives dissolved. The foam discs are then inserted into the Solution immersed and then in cold water, which has the consequence that the explosive is reflected on the walls of the foam pores in crystal form because it is insoluble in water.
Die Auflösung des Sprengstoffes in dem Aceton kann bei Zimmertemperatur erfolgen. Die Schaumstoffscheibe kann in dieser Lösung etwa 3 Minuten gehalten werden. Ohne Ausdrücken wird die Scheibe dann in dem Wasser während etwa 10 Minuten liegen gelassen. Alternativ kann sie ausgedrückt wurden, nachdem sie während einer kürzeren Zeit 9 wie 1 Minute unter der Wasseroberfläche gehalten worden ist.The explosive can be dissolved in the acetone at room temperature. The foam disc can be held in this solution for about 3 minutes. The disc is then left in the water for about 10 minutes without being squeezed out. Alternatively, it may have been expressed after being held under the surface of the water for a shorter time 9 such as 1 minute.
