Description
Schäleinrichtung mit mindestens einem Brenner und einem seine Austrittsbreite regelnden Steuerventil Schäleinrichtungen werden im allgemeinen für das Bearbeiten von Werkstücken verschieden großer Querschnitte eingerichtet. Da aus fertigungstechnischen Gründen die Schälbrenner und bei Pulverschälbrennern auch die Pulververteiler zur gegebenenfalls erforderlichen Zuführung eines Hilfspulvers in den Schälsauerstoffstrom in Standardgrößen von z. B. 180, 270 und 360 mm Breite hergestellt werden, ist es erforderlich, zur Erzielung eines großen Schälbreitenbereichs bis zu etwa 2 m oder größer, mehrere Brenner nebeneinander anzuordnen. Dieser große Schälbreitenbereich muß einstellbar sein, um auch Werkstücke von z. B. 500 mm Breite ohne Umbau der Schäleinrichtung bearbeiten zu können.Peeling device with at least one burner and one of its outlet widths regulating control valve peeling devices are generally used for machining set up of workpieces of different sized cross-sections. Because from production engineering Establish the peeling burners and, in the case of powder peeling burners, also the powder distributors if necessary, supply of an auxiliary powder into the peeling oxygen stream in standard sizes from z. B. 180, 270 and 360 mm width are produced, it is required to achieve a large peeling width range up to about 2 m or larger to arrange several burners next to each other. This large peel width range must be adjustable to accommodate workpieces of z. B. 500 mm width without conversion of the To edit peeling device.
Es ist bei Schäleinrichtungen mit einem einzigen Brenner bekannt, die Breite des aus mehreren öffnungen austretenden Sauerstoff- und Brenngasstromes durch je einen Kolbenschieber zu regulieren, der im Brenner angeordnet ist. Hierbei tritt das Problem der Regulierung mehrerer nebeneinander angeordneter Brenner nicht auf.It is known in peeling devices with a single burner, the width of the oxygen and fuel gas flow exiting from several openings to be regulated by a piston valve each, which is arranged in the burner. Here the problem of regulating several burners arranged next to one another does not arise on.
Gemäß der Erfindung wird bei Schäleinrichtungen mit mindestens einem Brenner, insbesondere Pulverschälbrenner, und je einem, die Austrittsbreite von-Brenngas und Sauerstoff oder Brenngas, Sauerstoff und Pulver regelnden Steuerventil, das eine Anzahl von axial nebeneinander angeordneten Steueröffnungen aufweist, die durch einen axial beweglichen Kolben verschließbar sind, vorgeschlagen, das Steuerventil getrennt und mit Abstand von dem Brenner anzuordnen.According to the invention, peeling devices with at least one Burners, especially powder peeling burners, and one each, the exit width of fuel gas and oxygen or fuel gas, oxygen and powder regulating control valve that has a number of axially juxtaposed control openings through an axially movable piston are closable, proposed the control valve to be arranged separately and at a distance from the burner.
Durch die Herausnahme des Steuerventils aus dem Brenner kann dieser klein und einfach ausgebildet werden. Da die Brenner die am meisten beanspruchten Teile .einer Schäleinrichtung sind und des öfteren ersetzt werden müssen, wird dadurch die Ersatzteilhaltung wesentlich verbilligt. Außerdem sind die beim gleichzeitig mehrseitigen Schälen zur Anpassung an den Schälquerschnitt zu verschiebenden Brenner entsprechend leichter und daher einfacher zu bewegen. Ferner entfallen durch das Herausnehmen des Steuerventils aus dem Brenner die Maßnahmen, die bisher erforderlich waren, um ein Funktionieren des Steuerventils auch bei der in unmittelbarer Nähe des Brenners beim Schälvorgang entstehenden großen Hitze Rechnung zu tragen.By removing the control valve from the burner, it can can be made small and simple. Because the burners are the most stressed Parts of a peeling device are and often have to be replaced the stock of spare parts is significantly cheaper. In addition, they are at the same time Multi-sided peeling to adapt to the peeling cross-section to be displaced burner accordingly lighter and therefore easier to move. Furthermore, the Removing the control valve from the burner the measures previously required were to ensure that the control valve was working even in the immediate vicinity of the burner during the peeling process to take into account the high heat.
Es wird außerdem durch die getrennte Anordnung des Steuerventils erfindungsgemäß die Möglichkeit geschaffen, einer Steueröffnung im Zylinder des Steuerventils mehrere Düsenkanäle für Sauerstoff, Brenngas oder Pulver zuzuordnen. Dabei kann an Stelle von mehreren kleinen Düsenkanälen eine einzige entsprechende schlitzförmige Austrittsöffnung vorgesehen sein. Durch eine im Steuerventil dicht beieinander liegende Anordnung der Anfänge der Leitungen zwischen Ventil und Brenner ist die Länge des Steuerventils zu verkürzen.It is also according to the invention by the separate arrangement of the control valve created the possibility of a control opening in the cylinder of the control valve several Allocate nozzle channels for oxygen, fuel gas or powder. Doing so can in place from several small nozzle channels a single corresponding slot-shaped outlet opening be provided. Due to an arrangement close together in the control valve the beginning of the lines between valve and burner is the length of the control valve To shorten.
Die vom Brenner getrennte Anordnung des Steuerventils hat ferner noch den Vorteil, daß die Steuerkolben jeweils für Sauerstoff, Brenngas und Pulver miteinander verbunden und mittels eines einzigen Betätigungsgliedes bewegt werden können. Beim gleichzeitig mehrseitigen Schälen können z. B. bei Werkstücken mit quadratischem Querschnitt 4 - 3 = 12 Brenner mittels eines einzigen Steuerventils reguliert werden.The separate arrangement of the control valve from the burner also has the advantage that the control pistons each for oxygen, fuel gas and powder with each other can be connected and moved by means of a single actuator. At the at the same time multi-sided peeling can be done, for. B. for workpieces with a square Cross-section 4 - 3 = 12 burners can be regulated by means of a single control valve.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung an Hand eines einem nicht dargestellten Brenner zugeordneten Pulververteilers veranschaulicht.An embodiment of the invention is shown in the drawing illustrates a powder distributor associated with a burner, not shown.
F i g. 1 zeigt einen Schnitt durch mehrere nebeneinander angeordnete Pulververteiler und das Steuerventil, F i g. 2 einen Schnitt gemäß Linie 11-I1 in F i g. 1. Die Pulververteiler 1 sind mit mehreren nebeneinander angeordneten Düsenkanälen 3 versehen, aus denen das Trägermedium in die Kanäle 10 tritt und das Pulver aus diesen herausbläst. Das Trägermedium, in vorliegendem Beispiel Preßluft, gelangt über eine Zuleitung 8 in den Kanal 4 des Steuerventils und von dort durch Öffnungen 9 über mehrere Schläuche 2 zu den Düsenkanälen 3. Um eine Verkürzung des Kanals 4 zu erreichen, werden drei Düsenkanäle 3 an je einen Schlauch 2 angeschlossen. Das Pulver fällt in die Kanäle 10 durch die Bohrung 7.F i g. 1 shows a section through several powder distributors arranged next to one another and the control valve, FIG. 2 shows a section along line 11-I1 in FIG. 1. The powder distributors 1 are provided with several juxtaposed nozzle channels 3, from which the carrier medium enters the channels 10 and blows the powder out of them. The carrier medium, in the present example compressed air, arrives via a feed line 8 in the channel 4 of the control valve and from there through openings 9 via several hoses 2 to the nozzle channels 3. To shorten the channel 4, three nozzle channels 3 are connected to one each Hose 2 connected. The powder falls into the channels 10 through the bore 7.
Die Regelung der Austrittsbreite des Pulvers aus den Kanälen 10 erfolgt durch Absperren bzw. Anschließen einer oder mehrerer Schläuche 2. an den Kanal 4, was mittels des Kolbenschiebers 5 geschieht. Da in den abgesperrten Schläuchen 2 und damit auch in den Kanälen 3 und 10 keine Preßluft vorhanden ist, kann kein Pulver aus den Kanälen 10 herausgeblasen werden.The control of the exit width of the powder from the channels 10 takes place by shutting off or connecting one or more hoses 2 to the channel 4, which is done by means of the piston valve 5. Since there is no compressed air in the blocked hoses 2 and thus also in the channels 3 and 10 , no powder can be blown out of the channels 10 .
Das Gestänge 6 des Kolbenschiebers 5, das durch Verkürzung des Kanals 4 kaum über die Pulververteiler 1 hervorsteht, weist eine Skala auf, auf der die eingestellte Flämmbreite ersichtlich ist.The linkage 6 of the piston valve 5, which by shortening the channel 4 barely protrudes over the powder distributor 1, has a scale on which the the set flame width can be seen.
