Description

Die Erfindung betrifft ein pulverkraftbetriebenes Setzgerät gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a powder-operated setting tool according to the preamble of Claim 1.

Zum Eintreiben von Befestigungselementen in harte Untergründe wie Beton, Gestein oder Stahl werden Setzgeräte verwendet, die mit Treibmittel enthaltenden Kartuschen antreibbar sind. Ein derartiges Setzgerät ist beispielsweise aus der FR-1 355 370 bekannt. Dieses Setzgerät weist in einem Führungszylinder einen Treibkolben und einen eine Kartuschenaufnahme aufweisenden Träger auf.For driving fasteners into hard surfaces such as concrete, stone or Steel setting tools are used, the cartridges containing propellant are drivable. Such a setting tool is known for example from FR-1 355 370. This setting tool has a driving piston and a one in a guide cylinder Cartridge having carrier.

Der Treibkolben befindet sich in einer Laufbohrung des Führungszylinders und ist parallel zur Setzrichtung versetzbar. Der Träger ist in einem entgegen der Setzrichtung liegenden Endbereich des Führungszylinders angeordnet und mit dem Führungszylinder verbunden. Neben der in einem entgegen der Setzrichtung weisenden Endbereich des Trägers angeordneten Kartuschenaufnahme besitzt der Träger eine erste Wirkfläche, die von einer in Setzrichtung weisenden Stirnseite des Trägers gebildet ist. Von dieser ersten Wirkfläche ragt zentral ein zylindrischer Vorsprung ab. Dieser Vorsprung ist mit einer ebenfalls in Setzrichtung weisenden zweiten Wirkfläche versehen. Eine die Kartuschenaufnahme mit der Laufbohrung verbindende Verbindungsbohrung durchsetzt den Träger.The driving piston is located in a running bore of the guide cylinder and is parallel can be moved to the setting direction. The carrier is in a direction opposite to the setting direction End region of the guide cylinder arranged and connected to the guide cylinder. In addition to the end region of the carrier pointing in the opposite direction to the setting direction arranged cartridge holder, the carrier has a first effective area, which of a is formed in the direction of the end face of the carrier. From that first A cylindrical projection protrudes centrally from the active surface. This lead is one also provided in the setting direction of the second effective surface. A the Cartridge receptacle with connecting bore connecting the barrel bore the carrier.

Der Treibkolben weist in einem entgegen der Setzrichtung weisenden Endbereich eine Vertiefung auf, die entgegen der Setzrichtung offen ausgebildet ist und in die der Vorsprung des Trägers eindringen kann. Da der Aussendurchmesser des Vorsprungs im wesentlichen dem Innendurchmesser der Vertiefung entspricht, erfolgt beim Zünden einer Kartusche nach einer anfänglichen hohen Beschleunigung ein abrupter Übergang auf eine geringe Beschleunigung, wenn der Vorsprung die Vertiefung verlässt. Durch diesen abrupten Übergang kommt es in der Brennkammer zu einem plötzlichen Druckabfall, so dass das Treibmittel nicht mehr zur Gänze verbrennen kann. Diese unvollständige Verbrennung führt zu einer übermässigen Verschmutzung des Setzgerätes. The driving piston has an end region pointing in the opposite direction to the setting direction Well, which is open against the setting direction and in which Protrusion of the wearer can penetrate. Since the outer diameter of the projection in corresponds essentially to the inner diameter of the recess, when igniting one Cartridge makes an abrupt transition to an after an initial high acceleration little acceleration when the protrusion leaves the recess. Through this abrupt transition there is a sudden drop in pressure in the combustion chamber, so that the blowing agent can no longer burn completely. This incomplete Combustion leads to excessive contamination of the setting tool.

Der Erfindung liegt die Aufgabe zugrunde, ein pulverkraftbetriebenes Setzgerät zu schaffen, bei dem zwecks einer vollständigen Verbrennung des Treibmittels der Treibkolben nach dem Zünden einer Kartusche anfangs eine hohe Beschleunigung erfährt, die im wesentlichen gleichmässig in eine geringe Beschleunigung übergeht, damit der Druckabfall in der Brennkammer nicht plötzlich erfolgt.The invention has for its object to a powder-powered setting tool create, in order to completely burn the propellant Driving piston after the ignition of a cartridge initially a high acceleration experiences, which changes substantially evenly into a low acceleration, so the pressure drop in the combustion chamber does not occur suddenly.

Die Lösung dieser Aufgabe erfolgt durch ein pulverkraftbetriebenes Setzgerät, welches die im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist.This problem is solved by a powder-operated setting tool, which the has in the characterizing section of claim 1 features.

Mit Hilfe des erfindungsgemässen Verbindungskanals wird bereits vor dem Beschleunigen bzw. kurz nach dem Beschleunigen des Treibkolbens in Setzrichtung ein Teil der bei der Zündung einer Kartusche entstehenden Treibgase zur ersten Wirkfläche des Trägers abgeleitet. Mit zunehmender Versetzung des Treibkolbens in Setzrichtung können sich die Treibgase und somit der von den Treibgasen erzeugte Druck auf die erste Wirkfläche verteilen. Der Druckabfall in der Vertiefung des Treibkolbens erfolgt dadurch langsam, sobald der Vorsprung des Trägers die Vertiefung verlässt.With the aid of the connection channel according to the invention, acceleration is carried out even before or shortly after accelerating the driving piston in the setting direction, part of the Ignition of a cartridge creates propellant gases to the first active surface of the carrier derived. With increasing displacement of the driving piston in the setting direction, the Propellants and thus the pressure generated by the propellants on the first active surface to distribute. The pressure drop in the recess of the driving piston takes place slowly, as soon as the protrusion of the wearer leaves the recess.

Aus herstelltechnischen Gründen erstreckt sich vorteilhafterweise der Verbindungskanal wenigstens teilweise über den Umfang des zylindrischen Vorsprungs und über die gesamte Länge des Vorsprungs.For technical reasons, the connecting channel advantageously extends at least partially over the circumference of the cylindrical projection and over the entire length of the projection.

Damit der von den Treibgasen erzeugbare Druck gleichmässig und auf die gesamte erste Wirkfläche verteilt werden kann, ist vorzugsweise der Verbindungskanal von einem Ringspalt zwischen der Aussenkontur des zylindrischen Vorsprungs und der Innenkontur der zylindrischen Vertiefung gebildet.So that the pressure that can be generated by the propellant gases is uniform and applies to the entire first Active area can be distributed, is preferably the connecting channel of one Annular gap between the outer contour of the cylindrical projection and the inner contour of the cylindrical recess.

Eine besonders gute und vollständige Verbrennung des pulverförmigen Treibmittels wird erreicht, wenn vorzugsweise die Querschnittsfläche des Verbindungskanals der 0,04 bis 0,5-fachen Querschnittsfläche der ersten Wirkfläche, reduziert um die zweite Wirkfläche, entspricht.A particularly good and complete combustion of the powdery propellant is reached when preferably the cross-sectional area of the connecting channel of 0.04 to 0.5 times the cross-sectional area of the first effective area, reduced by the second effective area, corresponds.

Um vor Beginn der Versetzung des Treibkolbens eine gute Ausbreitung des bei der Zündung einer Kartusche entstehenden Treibgasdruckes zwischen der zweiten Wirkfläche des Trägers und einem Boden der Vertiefung erreichen zu können, entspricht zweckmässigerweise die Länge des zylindrischen Vorsprungs der 0,5 bis 0,9-fachen Tiefe der zylindrischen Vertiefung. In order to ensure a good spread of the at the beginning of the displacement of the driving piston Ignition of a cartridge resulting propellant pressure between the second effective area to be able to reach the carrier and a bottom of the depression suitably corresponds the length of the cylindrical protrusion 0.5 to 0.9 times the depth of the cylindrical recess.

Ausgehend von einem entgegen der Setzrichtung weisenden freien Ende des Treibkolbens 6 - einer Anschlagfläche 13 - erstreckt sich im Kopf 8 in Setzrichtung eine zylindrische Vertiefung 12 mit dem Innendurchmesser D2. In diese Vertiefung 12 ragt der Vorsprung 11 des Trägers 3. Die parallel zur Setzrichtung gemessene Länge L1 des Vorsprungs 11 entspricht der 0,5 bis 0,9-fachen Tiefe L2 der Vertiefung 12. In Setzrichtung schliesst sich an die Vertiefung 12 beispielsweise ein sich verjüngender Bodenbereich an, der in Setzrichtung zu einer Spitze zuläuft.The driving piston 6 is composed of a head 8 and one in the setting direction to the head 8 adjoining shaft 7, the diameter of which is smaller than that Diameter of the head 8. The diameter of the head 8 essentially corresponds the diameter D of the bore 2.
