Definitions
- the present invention relates to a device for collecting the liquid jet of a liquid jet cutting machine.
- Such liquid jet cutting machines are known and are suitable for cutting a wide variety of materials, water being mostly used as the cutting liquid.
- the liquid jet flows out of a nozzle with a pressure of up to 4000 bar and allows the contact-free cutting of workpieces made of polystyrene, plasterboard, wood, non-woven fabric, leather, rubber, textiles etc.
- abrasives such as quartz sand, glass dust, corundum etc. are added to the cutting fluid.
- the radiation-shaped separation medium is directed onto the workpiece surface and the discharge nozzle is usually guided by means of a CAD control.
- the jet cuts through the material and emerges from the back of the same. Since the beam still has a very high residual energy even after it has left the cut material, it is essential to absorb it.
- the object of the present invention is to propose a light and very effective collecting device which is nevertheless robust and resistant and is not damaged or even destroyed by liquid jets which contain abrasive agents. Furthermore, the collecting device should also enable the cutting fluid and the abrasive to be collected easily and simply for reuse.
- a grate structure with an uneven surface arranged in a trough which preferably has grooves or channels running parallel to one another, forms a very resistant baffle surface on which the liquid jet always strikes at an oblique angle, so that the baffle surface is already protected by this design becomes.
- a protective covering made of ceramic plates increases the resistance of the grate construction, and the arrangement of passage points facilitates and ensures the collection of the cutting medium, which can be recycled.
- the proposed device not only enables dry cutting, but also cutting under water, which can mostly be carried out largely silently. Furthermore, when cutting underwater, the cutting quality of many objects is improved and the generation of dust is suppressed.
- the device has a tub 1, in which a grate structure 3 is installed above the tub bottom 2.
- the grate structure 3 has an uneven surface which comprises grooves or channels 9 running parallel to one another.
- the grate structure 3 is composed of a number of strips 4 and 5, all of which extend in mutually parallel directions, but lie in different planes. Two adjacent strips 4 and 5 are always in two planes which form an angle with one another, so that in the longitudinal direction of strips 4 and 5, channels or channels 9 are formed.
- the strips 4 and 5 are expediently formed from a perforated plate which can be processed by means of a sheet metal processing machine, e.g. with the help of a bending press, was brought into the form described.
- the strips 4 and 5 are provided with a covering, appropriately sized ceramic plates 6 and 7 are used, which cover the strips 4 and 5 such that a passage 8 remains between two abutting ceramic plates.
- the strips 4 and 5 or the ceramic plates 6 and 7 delimit the above-mentioned channels or channels 9, which are expediently provided with gravel or with a glass filling 10.
- the actual cutting device 3 consists of a known, only strictly schematically indicated liquid jet cutting machine 13, which is arranged on a support device 14 adjustable in at least two directions.
- the grating structure 3 formed from the perforated plates is never directly exposed to the cutting beam 15, in that the cutting beam never strikes the grating structure at a right angle, so that it is not subjected to great stress and cannot be damaged.
- the gravel or glass filling further weakens the effect of the cutting jet on the wall of the tub. It is thus possible to work with very high pressure and with abrasives, the water jet losing a large part of its energy in contact with the gravel or glass filling 10 and then escaping through the passage points 8 and the perforated plates into the tub 1, where the Cutting fluid and the abrasive can be collected for reuse.
- the tub 1 is filled with water to such an extent that the grate structure 3 together with ceramic plates 6 and 7 and together with the gravel or glass filling 10 are under water. It is also possible to arrange the grid 11 together with the workpiece 12 below the water level and to carry out the cutting entirely under water. This has the great advantage that cutting can be carried out with little noise and the cutting quality of many objects is improved. Dust generation is also prevented.
- underwater cutting cannot be used for every material and in particular porous materials cannot be cut under water.
- the water When cutting dry, the water is drained continuously, if necessary treated and recycled.

Abstract
Description
Die vorliegende Erfindung bezieht sich auf eine Einrichtung zum Auffangen des Flüssigkeitsstrahls einer Flüssigkeitsstrahl-Schneidmaschine.The present invention relates to a device for collecting the liquid jet of a liquid jet cutting machine.
Solche Flüssigkeitsstrahl-Schneidmaschinen sind bekannt und eignen sich zum Schneiden der verschiedensten Materialien, wobei als Schneidflüssigkeit meistens Wasser verwendet wird. Der Flüssigkeitsstrahl entströmt einer Düse mit einem Druck von bis zu 4000 bar und erlaubt das berührungslose Schneiden von Werkstücken aus Styropor, Rigips, Holz, Fliesstoffen, Leder, Gummi, Textilien etc. Zum Schneiden von härteren Materialien, wie Metall, Glas, Stein und dgl. werden der Schneidflüssigkeit Abrasivmittel wie Quarzsand, Glasstaub, Korund etc. beigemischt.Such liquid jet cutting machines are known and are suitable for cutting a wide variety of materials, water being mostly used as the cutting liquid. The liquid jet flows out of a nozzle with a pressure of up to 4000 bar and allows the contact-free cutting of workpieces made of polystyrene, plasterboard, wood, non-woven fabric, leather, rubber, textiles etc. For cutting harder materials such as metal, glass, stone and the like abrasives such as quartz sand, glass dust, corundum etc. are added to the cutting fluid.
Das strahlenförmige Trennmedium wird auf die Werkstückoberfläche gerichtet und die Ausströmdüse meistens mittels einer CAD-Steuerung geführt. Der Strahl durchtrennt den Werkstoff und tritt auf der Rückseite desselben wieder aus. Da der Strahl auch nach dem Austritt aus dem geschnittenen Werkstoff noch eine sehr hohe Restenergie besitzt, ist es unumgänglich, diese zu absorbieren.The radiation-shaped separation medium is directed onto the workpiece surface and the discharge nozzle is usually guided by means of a CAD control. The jet cuts through the material and emerges from the back of the same. Since the beam still has a very high residual energy even after it has left the cut material, it is essential to absorb it.
Es wurde bereits vorgeschlagen hinter oder unter dem Werkstück ein Wasserbecken anzuordnen, in welchem der Schneidstrahl aufgefangen wird. Das Wasserbecken muss dabei eine dicke und widerstandsfähige Wandung besitzen, auf welche der Schneidstrahl auftrifft, wobei es insbesondere bei der Verwendung von Abrasivmitteln oft nicht zu vermeiden ist, dass die Wandung des Wasserbeckens beschädigt oder sogar zerstört wird. Um dies zu verhüten, hat man bereits vorgeschlagen, im Wasserbecken ein Kugelbett anzuordnen, welches aus einer Wanne besteht, die mit Kugeln aus Chromstahl oder Glas gefüllt ist. Eine solche Vorrichtung hat sich grundsätzlich bewährt, ist jedoch verhältnismässig gross, dementsprechend schwer und auch teuer. Die Rückgewinnung der Abrasivmittel ist mit grossen Schwierigkeiten verbunden und oft gar nicht möglich.It has already been proposed to arrange a water basin behind or under the workpiece, in which the cutting jet is caught. The water basin must have a thick and resistant wall on which the cutting jet strikes, whereby it is often unavoidable that the wall of the water basin is damaged or even destroyed, especially when using abrasives. In order to prevent this, it has already been proposed to arrange a ball bed in the water basin, which consists of a tub which is filled with balls made of chrome steel or glass. Such a device has proven itself in principle, but is relatively large, correspondingly heavy and also expensive. The recovery of the abrasives is very difficult and often not possible at all.
Aufgabe der vorliegenden Erfindung ist es, eine leichte und sehr wirksame Auffangvorrichtung vorzuschlagen, welche trotzdem robust und widerstandsfähig ist und auch durch Flüssigkeitsstrahlen, die Abrasivmittel enthalten, nicht beschädigt oder sogar zerstört wird. Ferner soll die Auffangvorrichtung auch ein leichtes und einfaches Sammeln der Schneidflüssigkeit und der Abrasivmittel zwecks Wiederverwendung ermöglichen.The object of the present invention is to propose a light and very effective collecting device which is nevertheless robust and resistant and is not damaged or even destroyed by liquid jets which contain abrasive agents. Furthermore, the collecting device should also enable the cutting fluid and the abrasive to be collected easily and simply for reuse.
Zu diesem Zweck wird eine Einrichtung zum Auffangen des Flüssigkeitsstrahls einer Flüssigkeitsstrahl-Schneidmaschine gemäss dem Oberbegriff von Anspruch 1 vorgeschlagen, welche nach den kennzeichnenden Merkmalen dieses Anspruchs ausgebildet ist.For this purpose, a device for collecting the liquid jet of a liquid jet cutting machine according to the preamble of claim 1 is proposed, which is designed according to the characterizing features of this claim.
Durch die Verwendung einer in einer Wanne angeordneten Rostkonstruktion mit unebener Oberfläche, die vorzugsweise parallel zueinander verlaufende Rillen oder Kanäle aufweist, wird eine sehr widerstandsfähige Prallfläche gebildet, auf die der Flüssigkeitsstrahl immer unter einem schrägen Winkel auftrifft, so dass die Prallfläche schon durch diese Ausbildung geschont wird. Die Verwendung eines Schutzbelages aus Keramikplatten erhöht die Widerstandsfähigkeit der Rostkonstruktion, und die Anordnung von Durchlaßstellen erleichtert und sichert das Auffangen des Schneidmediums, welches der Wiederverwendung zugeführt werden kann.The use of a grate structure with an uneven surface arranged in a trough, which preferably has grooves or channels running parallel to one another, forms a very resistant baffle surface on which the liquid jet always strikes at an oblique angle, so that the baffle surface is already protected by this design becomes. The use of a protective covering made of ceramic plates increases the resistance of the grate construction, and the arrangement of passage points facilitates and ensures the collection of the cutting medium, which can be recycled.
Ferner wird mit der vorgeschlagenen Einrichtung nicht nur das Trockenschneiden, sondern auch das Schneiden unter Wasser ermöglicht, welches meistens weitgehend geräuschlos ausgeführt werden kann. Ferner wird beim Schneiden unter Wasser die Schnittqualität bei vielen Objekten verbessert und die Staubentwicklung unterdrückt.Furthermore, the proposed device not only enables dry cutting, but also cutting under water, which can mostly be carried out largely silently. Furthermore, when cutting underwater, the cutting quality of many objects is improved and the generation of dust is suppressed.
Auf beiliegender Zeichnung ist ein Ausführungsbeispiel einer vorgeschlagenen Einrichtung im Vertikalschnitt schematisch dargestellt.On the accompanying drawing, an embodiment of a proposed device is shown schematically in vertical section.
Die Einrichtung weist eine Wanne 1 auf, in welche oberhalb des Wannenbodens 2 eine Rostkonstruktion 3 eingebaut ist. Die Rostkonstruktion 3 weist eine unebene Oberfläche auf, die parallel zueinander verlaufende Rinnen oder Kanäle 9 umfasst. Die Rostkonstruktion 3 setzt sich aus einer Anzahl von Streifen 4 und 5 zusammen, die sich alle in parallel zueinander verlaufenden Richtungen erstrecken, aber in verschiedenen Ebenen liegen. Zwei benachbarte Streifen 4 und 5 liegen immer in zwei Ebenen, die einen Winkel miteinander einschliessen, so dass in der Längsrichtung der Streifen 4 und 5 Rinnen oder Kanäle 9 entstehen. Die Streifen 4 und 5 werden zweckmässigerweise aus einer Lochplatte gebildet, die mittels einer Blechbearbeitungsmaschine, z.B. mit Hilfe einer Biegepresse, in die erläuterte Form gebracht wurde.The device has a tub 1, in which a grate structure 3 is installed above the
Anstelle der erläuterten und in der Zeichnung dargestellten Form der Rostkonstruktion, kann diese auch anders, z.B. wellblechartig geformt sein. Wesentlich ist nur, dass die Rostkonstruktion gesamthaft keine ebene Oberfläche besitzt.Instead of the grate construction described and shown in the drawing, this can also be done differently, e.g. be shaped like a corrugated sheet. The only important thing is that the entire grate structure does not have a flat surface.
Die Streifen 4 und 5 sind mit einem Belag versehen, wobei zweckmässigerweise entsprechend bemessene Keramikplatten 6 und 7 zur Verwendung gelangen, welche die Streifen 4 bzw. 5 derart bedecken, dass zwischen zwei aneinander anstossenden Keramikplatten je eine Durchlaßstelle 8 verbleibt. In der erwähnten Weise begrenzen die Streifen 4 und 5 bzw. die Keramikplatten 6 und 7 die erwähnten Rinnen oder Kanäle 9, welche zweckmässigerweise mit Kies oder mit einer Glasfüllung 10 versehen werden.The
Oberhalb der Rostkonstruktion 3 ist ein Gitter 11 zur Aufnahme des zu schneidenden Werkstücks 12 vorhanden. Die eigentliche Schneideinrichtung 3 besteht aus einer an sich bekannten, nur streng schematisch angedeuteten Flüssigkeitsstrahl-Schneidmaschine 13, welche auf einer Tragvorrichtung 14 in mindestens zwei Richtungen verstellbar angeordnet ist.Above the grate structure 3 there is a
In der beschriebenen Weise ist die aus den Lochplatten gebildete Rostkonstruktion 3 nie direkt dem Schneidstrahl 15 ausgesetzt, indem der Schneidstrahl nie unter rechtem Winkel auf die Rostkonstruktion trifft, so dass diese nicht stark beansprucht wird und nicht beschädigt werden kann. Darüberhinaus schwächt die Kies- oder Glasfüllung die Wirkung des Schneidstrahles auf die Wandung der Wanne noch weiter ab. Es wird somit ermöglicht, mit sehr hohem Druck und mit Abrasivmitteln zu arbeiten, wobei der Wasserstrahl in Kontakt mit der Kies- oder Glasfüllung 10 einen grossen Teil seiner Energie verliert und anschliessend durch die Durchlaßstellen 8 und die Lochplatten in die Wanne 1 entweicht, wo die Schneidflüssigkeit und das Abrasivmittel zur Wiederverwendung gesammelt werden können.In the manner described, the grating structure 3 formed from the perforated plates is never directly exposed to the
Mit der beschriebenen Einrichtung ist wahlweise das Schneiden unter Wasser oder auch trocken möglich. Beim Schneiden unter Wasser wird die Wanne 1 soweit mit Wasser gefüllt, dass die Rostkonstruktion 3 samt Keramikplatten 6 und 7 und samt der Kies- oder Glasfüllung 10 unter Wasser stehen. Es ist auch möglich, das Gitter 11 samt Werkstück 12 unterhalb des Wasserspiegels anzuordnen und das Schneiden vollständig unter Wasser durchzuführen. Dies bringt den grossen Vorteil mit sich, dass das Schneiden mit geringer Lärmentwicklung erfolgen kann und die Schnittqualität bei vielen Objekten verbessert wird. Auch die Staubentwicklung wird unterbunden. Das Unterwasserschneiden ist jedoch nicht für jedes Material anwendbar und insbesondere kön- nen poröse Materialen nicht unter Wasser geschnitten werden.With the described device, cutting under water or dry is possible. When cutting under water, the tub 1 is filled with water to such an extent that the grate structure 3 together with ceramic plates 6 and 7 and together with the gravel or
Beim Trockenschneiden wird das Wasser kontinuierlich abgelassen, gegebenenfalls aufbereitet und der Wiederverwendung Zugeführt.When cutting dry, the water is drained continuously, if necessary treated and recycled.
