Description

Die Erfindung bezieht sich auf eine Explosionskammer gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an explosion chamber according to the preamble of claim 1.

Aus der DE-A-26 45 347 ist eine Anlage nach dem Oberbegriff des Patentanspruchs 1 zur Explosionsbearbeitung von Werkstoffen bekannt, bei welcher ein Objekttisch aus Metallplatten mit dazwischen angeordneten Zwischenlagen besteht, deren Schallhärte sich von der Schallhärte der Metallplatten unterscheidet. Insbesondere ist bei dieser Anlage nachteilig, daß die Metallplatten beweglich, z.B. durch Metallstäbe miteinander verbunden sind. Mit einem derartigen Objekttisch ist bei größeren Sprengleistungen ein hinreichendes Abklingen der Stoßwelle nicht zu erreichen, so daß eine Beschädigung des Fundaments, in welchem der Objekttisch ruht, zu befürchten ist. Außerdem können sich die Metallstäbe bei einer Sprengung aufgrund der Belastung auf den Objekttisch verbiegen, wodurch ein weiterer Einsatz der Anlage nicht mehr möglich ist.From DE-A-26 45 347 a system according to the preamble of claim 1 for explosion processing of materials is known, in which an object table consists of metal plates with interposed intermediate layers, the sound hardness of which differs from the sound hardness of the metal plates. A particular disadvantage of this system is that the metal plates are movable, e.g. are connected by metal rods. With such an object stage, sufficient decay of the shock wave cannot be achieved with larger explosive powers, so that damage to the foundation in which the object stage rests is to be feared. In addition, the metal bars can bend due to the load on the object table during a detonation, which means that further use of the system is no longer possible.

Bei der aus der DE-A-16 52 627 bekannten Anlage stützt sich der Arbeitstisch unter Zwischenschaltung von Federelementen auf einem Betonfundament ab. Die Oberseite des Arbeitstisches ist mit einer Gummiauflage beschichtet, die selbst wiederum an ihrer Oberseite mit einer Ausnehmung zur Aufnahme einer Sandschicht ausgerüstet sein soll. Der Arbeitstisch ist unstabil und weist eine relativ kurze Lebensdauer auf, so daß mit solchen Anlage im technologischen Fertigungsablauf keine Wirtschaftlichkeit erzielbar ist und größere Werkstücke nicht bearbeitet werden können.In the system known from DE-A-16 52 627, the work table is supported on a concrete foundation with the interposition of spring elements. The top of the work table is coated with a rubber pad, which in turn should be equipped with a recess on its top to accommodate a layer of sand. The work table is unstable and has a relatively short lifespan, so that no economy can be achieved with such a system in the technological production process and larger workpieces cannot be processed.

Aus der DE-A-19 33 276 ist eine Vorrichtung zum Verformen von Großronden mittels Druckwellen bekannt, die mit einem wassergefüllten Sprengbehälter arbeitet. Auch hier sind zwischen dem eigentlichen Fundament und dem Arbeitstisch Federn eingeschaltet, die eine elastische Abstützung des Arbeitstisches gegenüber dem relativ steifen und starren Fundament erbringen sollen, aber einen unstabilen Arbeitstisch schaffen. Auch hier treten bei großtechnischen Anlagen sofort Zerstörungen dieser elastischen Lagerungen auf, die die Anlage betriebswirtschaftlich nicht einsatzfähig machen.From DE-A-19 33 276 a device for deforming large round blanks by means of pressure waves is known, which works with a water-filled detonator. Here, too, springs are connected between the actual foundation and the work table, which are intended to provide elastic support for the work table in relation to the relatively rigid and rigid foundation, but which create an unstable work table. Here, too, occur in large-scale plants Immediately destroy these elastic bearings, which make the system unusable from an economic point of view.

Schließlich ist es aus der DE-A-15 27 523 bekannt, die eigentliche Sprengkammer nach Einbringen des zu bearbeitenden Werkstückes auf Vakuum leerzupumpen, um derart Stoß- und Schallwellen in der Atmosphäre und die seismischen Wellen im Erdboden weitgehend zu vermeiden. Hierbei besteht die Sprengkammer aus einem kugelförmigen Behälter, der auf einem relativ kleinen Fundament aufruht, wobei vorzugsweise die Abstützung des Behälters an diesem kleinen Fundament wiederum unter Zwischenschaltung von Federn erfolgen soll. Der Behälter weist ein geringes Innenvolumen auf und dient nicht der großtechnischen Bearbeitung von Werkstücken.Finally, it is known from DE-A-15 27 523 to pump the actual explosive chamber empty after the workpiece to be machined has been introduced in order to largely avoid shock and sound waves in the atmosphere and the seismic waves in the ground. Here, the blasting chamber consists of a spherical container, which rests on a relatively small foundation, the container being preferably supported on this small foundation again with the interposition of springs. The container has a small internal volume and is not used for the industrial processing of workpieces.

Der Erfindung liegt die Aufgabe zugrunde, eine Anlage zu schaffen, bei welcher im großtechnischen Fertigungsprogramm die Explosionsbearbeitung von Metallen vorgenommen werden kann und bei welcher nicht nur die eigentliche Sprengkammer, sondern auch der Arbeitstisch eine hohe Lebensdauer und damit hohe Leistungsfähigkeit aufweist, wobei gleichzeitig die Umweltbelastung durch Schall und seismische Wellen auf ein Minimum beschränkt wird.The invention has for its object to provide a system in which the explosion processing of metals can be carried out in the industrial production program and in which not only the actual explosive chamber, but also the work table has a long service life and thus high performance, while at the same time the environmental impact is kept to a minimum by sound and seismic waves.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Merkmals gemäß dem Patentanspruch 1 gelöst.This object on which the invention is based is achieved by the features according to patent claim 1.

Mit anderen Worten ausgedrückt: Durch die Erfindung wird erreicht, daß durch die quasi elastische Ausbildung des Arbeitstisches und sein Einlassen im und Verbinden mit dem Fundament ein langlebiger Arbeitstisch geschaffen wird, der in der Lage ist, die auftretenden Wellen zu absorbieren, wobei gleichzeitig auch das Fundament unmittelbar mit herangezogen wird, um diese seismischen Wellen zu vernichten. Es wird ein großer freier Raum, d.h. Arbeitsraum, geschaffen, wobei die eigentliche Stahlkuppel verfahrbar ausgebildet sein kann oder kippbar ausgebildet sein kann und somit entweder in einer Arbeitsstellung über dem Arbeitstisch oder in eine Freigabestellung führbar ist. Durch den Einsatz einer in vertikalen Richtung wirkenden und die Stahlkuppel gegenüber dem Fundament abdichtenden Dichtung wird dabei gleichzeitig im Einsatz einer Vakuumanlage erreicht, daß die Abdichtung und damit Abstützung der Stahlkuppel auf dem Fundament verbessert wird, da aufgrund des innerhalb der Stahlkuppel herrschenden Vakuums der atmosphärische Druck die Anlage der Stahlkuppel am Fundament verbessert. Gleichzeitig wirkt die Vakuumanlage im Inneren in an sich bekannter Welse dahingehend, daß Druckwellen vermindert werden und dadurch die Gesamtanlage umweltfreundlicher wird.In other words, the invention achieves that the quasi-elastic design of the work table and its insertion in and connection to the foundation create a long-lasting work table which is capable of absorbing the waves which occur, while at the same time also Foundation is used directly to destroy these seismic waves. It becomes a large free space, i.e. Working space, created, the actual steel dome can be designed to be movable or tiltable and can thus be guided either in a working position above the work table or in a release position. Through the use of a seal that acts in the vertical direction and seals the steel dome against the foundation, the use of a vacuum system at the same time achieves that the sealing and thus support of the steel dome on the foundation is improved, since due to the vacuum prevailing within the steel dome, the atmospheric pressure improved the position of the steel dome on the foundation. At the same time, the vacuum system inside works in a manner known per se to the effect that pressure waves are reduced and the entire system thereby becomes more environmentally friendly.

Durch die Anordnung einer die Stahlkuppel übergreifenden Krananlage, ist ein einfaches Beschicken des Arbeitstisches möglich, so daß auch große Werkstücke gehandhabt werden können.The arrangement of a crane system spanning the steel dome makes it easy to load the work table, so that even large workpieces can be handled.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert.An embodiment of the invention is explained below with reference to the drawing.

In der Zeichnung ist mit 1 ein entsprechend schweres, beispielsweise aus Beton bestehendes Fundament bezeichnet, auf dem eine Haube 12 aufruht, und zwar unter Zwischenschaltung entsprechender Dichtungen 6, wobei die Haube 12 den eigentlichen Kammerhohlraum K schafft.In the drawing, 1 denotes a correspondingly heavy foundation, for example made of concrete, on which a hood 12 rests, with the interposition of corresponding seals 6, the hood 12 creating the actual chamber cavity K.

Dieser Kammerhohlraum K kann durch eine in der Zeichnung nicht dargestellte Vakuumanlage evakuiert werden, so daß dadurch zusätzlich die Haube 12 abdichtend auf die Dichtungen 6 aufgepreßt wird.This chamber cavity K can be evacuated by a vacuum system, not shown in the drawing, so that the hood 12 is thereby additionally pressed onto the seals 6 in a sealing manner.

Innerhalb des Fundamentes 1 ist eine Ausnehmung vorgesehen, die einen Arbeitstisch 11 aufnimmt, der aus verschiedenen Zwischenschichten 4 aufgebaut ist, wobei die oberste Zwischenschicht 4 die Werkstückauflagefläche 9 schafft. Die verschiedenen Zwischenschichten 4 bestehen aus Werkstoffen, die die potentielle Energie der Druckwelle in kinetische Energie der Einbaumaterialien umwandelt, wobei die mittlere Dichte der aufeinanderfolgenden Zwischenschicten 4 zwischen Werten von 500 bis 15000 kgm⁻³ wechselt. Die Zwischenschichten 4 können dabei durchgehend in horizontaler Richtung ausgebildet sein, können aber auch - wie dies in der Zeichnung dargestellt ist - durch einzelne kassettenartige Aufnahmefächer gebildet werden.A recess is provided within the foundation 1, which receives a work table 11 which is constructed from various intermediate layers 4, the uppermost intermediate layer 4 creating the workpiece support surface 9. The various intermediate layers 4 consist of materials which convert the potential energy of the pressure wave into the kinetic energy of the installation materials, the average density of the successive intermediate layers 4 changing between values of 500 to 15000 kgm⁻³. The intermediate layers 4 can be formed continuously in the horizontal direction, but can also - as shown in the drawing - be formed by individual cassette-like receiving compartments.

Der im Fundament 1 vorgesehene Hohlraum weist in seinen Umfangsbereichen eine vorzugsweise aus einer Sand füllung od. dgl. bestehende Wandauskleidung 8 auf, die gegenüber den Zwischenschichten 4 durch eine Wand 3 abgetrennt ist, die zwar als großes Viereck einteilig ausgebildet sein kann, aber lose, d.h. ohne jede Verbindung mit dem Fundament 1, in den entsprechenden Hohlraum eingesetzt ist. Diese Sand- oder Rieselkornfüllung besteht ebenfalls aus Materialien, die die potentielle Energie der Druckwelle in kinetische Energie der Einbaumaterialien umwandeln. Die Zwischenschichten 4 können dabei aus Holz, Holzspänen, Metallspänen, Sand od. dgl. bestehen, wobei diese Materialien entsprechend gemischt sein können und vorverdichtet sein können, wobei bei Auftreten der Wellen die Sandfüllung in diesen verdichteten Vormaterialien sich bewegen kann.The cavity provided in the foundation 1 has in its circumferential areas a wall liner 8, preferably made of sand or the like, which is separated from the intermediate layers 4 by a wall 3, which is in one piece formed as a large square can, but loose, ie without any connection to the foundation 1, is inserted into the corresponding cavity. This sand or trickle grain filling also consists of materials that convert the potential energy of the pressure wave into the kinetic energy of the paving materials. The intermediate layers 4 can consist of wood, wood shavings, metal shavings, sand or the like. These materials can be mixed accordingly and can be pre-compressed, and when the waves occur, the sand filling in these compressed materials can move.

Der Obergang von der Werkstückauflagefläche 9 zu den Randbereichen des Kammerhohlraumes K wird durch sich in den Randbereichen schräg nach oben erstreckende Leitbleche 5 gebildet, die damit einen Schutz der Dichtungen 6 und der Verbindungsbereiche der Haube 12 zum Fundament 1 hin bewirken. Auch diese Leitbleche können aus kassettenförmigen Metallelementen gebildet sein, die nach außen hin offen sind und trotzdem aber eine Sand- oder Rieselkornfüllung aufweisen können.The transition from the workpiece support surface 9 to the edge regions of the chamber cavity K is formed by baffles 5 which extend obliquely upwards in the edge regions and thus protect the seals 6 and the connection regions of the hood 12 to the foundation 1. These baffles can also be formed from cassette-shaped metal elements that are open to the outside and can nevertheless have a sand or trickle grain filling.

Die Zwischenschichten 4 stützen sich am Boden 14 des im Fundament 1 ausgenommenen Raumes ebenfalls unter Zwischenschaltung einer Schicht aus Sand oder Rieselkorn ab.The intermediate layers 4 are supported on the floor 14 of the space recessed in the foundation 1, also with the interposition of a layer of sand or grit.

Der eigentliche Kammerhohlraum K wird nach oben hin durch Blechmäntel 2 abgeschlossen, wobei in dem dargestellten Ausführungsbeispiel zwei solcher Blechmäntel vorgesehen sind, zwischen denen ebenfalls eine schwingungsabsorbierende Masse eingebracht wird. Zusätzlich ist in dem Kammerhohlraum K ein Abfangssystem 7 vorgesehen, das aus kassettenförmigen Elementen besteht, wobei die Erstreckung dieser kassettenförmig ausgebildeten Deckenelemente horizontal oder - wie in der Zeichnung dargestellt - auch leicht gewolbt sein kann. Wird das leicht gewolbte Abfangsystem 7 im oberen Bereich der Haube 12 eingesetzt, kann die zu den Blechmanteln 2 hingerichtete Seite verschlossen sein und dann der so geschaffene Raum B ebenfalls eine Sandfullung aufweisen.The actual chamber cavity K is closed at the top by sheet metal shells 2, two such sheet metal shells being provided in the exemplary embodiment shown, between which a vibration-absorbing mass is likewise introduced. In addition, an interception system 7 is provided in the chamber cavity K, which consists of cassette-shaped Elements exist, wherein the extension of these cassette-shaped ceiling elements can be horizontal or - as shown in the drawing - also slightly curved. If the slightly curved interception system 7 is used in the upper region of the hood 12, the side which is directed towards the sheet metal sheaths 2 can be closed and then the space B created in this way also has sand filling.

Das ganze kann nach außen hin dann durch einen zusatzlichen Blechmantel 2a abgeschlossen werden.The whole can then be closed to the outside by an additional sheet metal jacket 2a.

Die ggf. zum Bewegen der Haube 12 erforderliche Krananlage ist ebenso wie die Vakuumanlage in der Zeichnung nicht dargestellt.The crane system that may be required to move the hood 12, like the vacuum system, is not shown in the drawing.
