Description

Die Erfindung betrifft ein Eintreibgerät, insbesondere ein handgeführtes Eintreibgerät, nach dem Oberbegriff des Anspruchs 1.The invention relates to a tacker, in particular a hand-held tacker, according to the preamble of claim 1.

DE 102 26 878 A1 beschreibt ein Eintreibgerät zum Eintreiben eines Nagels in ein Werkstück, bei dem eine Brennkammer mit einem Brenngas beschickt wird, wobei nach einem Zündvorgang ein Eintreibkolben gegen den Nagel beschleunigt wird. Die Brennkammer hat einen verstellbaren Brennkammerboden, wobei eine Stellstange mittels einer Durchführung durch ein Gehäuse der Brennkammer geführt ist und mit dem verstellbaren Brennkammerboden verbunden ist. Der Brennkammerboden ist durch eine umlaufende Dichtung gegen die Brennkammerwand abgedichtet. Ein ähnliches Eintreibgerät ist auch aus EP 2 465 643 A2 bekannt. Es ist die Aufgabe der Erfindung, ein Eintreibgerät anzugeben, das einen besonders zuverlässigen Betrieb auch bei niedrigen Umgebungstemperaturen ermöglicht.
Diese Aufgabe wird für ein eingangs genanntes Eintreibgerät erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch den axialen Vorstand bzw. das Vorragen der Dichtung vor die Abschlussebene der Nut wird Wasser, das auf der Brennkammerwand haftet, bei einem Verstellen des Bodens effektiv abgestreift, ohne übermäßig in die Nut einzutreten. Insbesondere bei Temperaturen unter dem Gefrierpunkt wird hierdurch ein Einfrieren von Wasser im Nutbereich vermieden.
Der gegenüber der Brennkammerwand verstellbare Boden der Brennkammer erlaubt es allgemein, dass die Brennkammer zum Beispiel als Teil einer Sicherheitseinrichtung kollabiert werden kann, wenn das Gerät nicht ordnungsgemäß auf ein Werkstück aufgesetzt ist. Bei solchen Geräten wird die Brennkammer vor jedem Setzborgang durch das Aufsetzen aufgespannt, so dass jeweils ein Überstreifen der Brennkammerwand erfolgt. DE 102 26 878 A1 describes a driving tool for driving a nail into a workpiece in which a combustion chamber is charged with a fuel gas, wherein after a firing process, a driving piston is accelerated against the nail. The combustion chamber has an adjustable combustion chamber floor, wherein an actuating rod is guided by means of a passage through a housing of the combustion chamber and is connected to the adjustable combustion chamber floor. The combustion chamber bottom is sealed by a circumferential seal against the combustion chamber wall. A similar tacker is also off EP 2 465 643 A2 known. It is the object of the invention to provide a tacker that allows a particularly reliable operation even at low ambient temperatures.
This object is achieved according to the invention for a drive-in device mentioned above with the characterizing features of claim 1. By the axial board or the protrusion of the seal in front of the final plane of the groove water that adheres to the combustion chamber wall, effectively stripped when adjusting the soil without excessively entering the groove. In particular, at temperatures below freezing, thereby freezing of water in the groove area is avoided.
The bottom of the combustion chamber, which is adjustable with respect to the combustion chamber wall, generally allows the combustion chamber to be collapsed, for example as part of a safety device, if the device is not properly seated on a workpiece. In such devices, the combustion chamber is clamped before each Setzborgang by placing it, so that in each case a Überstreifen the combustion chamber wall takes place.

Bei einer allgemein bevorzugten Ausführungsform der Erfindung ragt die vordere Fläche der Dichtung in Richtung der Achse über eine Abschlussebene des Bodens vor. Dies erlaubt ein besonders effektives Ableiten des abgestreiften Wassers vorbei an dem Spalt zwischen Boden und Brennkammerwand.In a generally preferred embodiment of the invention, the front surface of the gasket protrudes in the direction of the axis beyond a plane of termination of the bottom. This allows a particularly effective discharge of the stripped water past the gap between the bottom and the combustion chamber wall.

Allgemein vorteilhaft wird das Ableiten des abgestreiften Wassers dadurch unterstützt, dass ein in radial inneres Ende der vorderen Fläche einen scharfkantigen Abschluss aufweist. Bevorzugt hat der scharfkantige Abschluss eine Kante mit einem Winkel zwischen 30° und 120°, besonders bevorzugt zwischen 70° und 110°. Einer solche Kante bildet eine Sperre für das abgestreifte Wasser, das hierdurch kaum um die Kante herum in den Spalt zwischen Boden und Brennkammer eindringen kann.Generally, the discharge of the stripped water is assisted by having a sharp-edged termination in the radially inner end of the front surface. Preferably, the sharp-edged finish has an edge with an angle between 30 ° and 120 °, more preferably between 70 ° and 110 °. Such an edge forms a barrier to the stripped water, which thereby can hardly penetrate around the edge into the gap between the bottom and the combustion chamber.

Zur weiteren Verbesserung der Ableitung des Wassers ist an dem Brennkammerboden und/oder im Bereich der Brennkammerwand eine Ausnehmung zur Abführung von durch die Dichtung abgestreiftem Wasser angeordnet. Dies erlaubt auch das Ableiten größerer Mengen von an der Brennkammerwand kondensiertem Wasser.To further improve the discharge of the water, a recess for discharging water stripped off by the seal is arranged on the combustion chamber bottom and / or in the region of the combustion chamber wall. This also allows the discharge of larger amounts of condensed water on the combustion chamber wall.

Allgemein vorteilhaft ragt die Dichtung beiderseitig über die Abschlussebene der Nut vor, so dass ein Eindringen von Wasser in den Spalt in beiden axialen Bewegungsrichtungen des Bodens vermieden wird. Bei einfachen Ausführungsformen kann die Dichtung insbesondere symmetrisch ausgeformt sein.Generally advantageous, the seal protrudes on both sides over the final plane of the groove, so that penetration of water into the gap in both axial directions of movement of the bottom is avoided. In simple embodiments, the seal may in particular be formed symmetrically.

Bei einer besonders bevorzugten Ausführungsform der Erfindung umfasst die Dichtung einen in Umfangsrichtung offenen Dichtungsring. Hierdurch können auch Dichtungsringe aus formsteifem Material in die Nut eingesetzt werden. Allgemein bevorzugt besteht der der Dichtungsring dabei aus einem harten Dichtstoff. Unter einem harten Dichtstoff wird dabei ein Material verstanden, das im dichtenden Zustand nicht bzw. nicht sichtbar elastisch deformiert ist. Ein solches Material kann zum Beispiel ein Metall wie Stahl, Kupfer oder Aluminium sein oder auch ein harter, insbesondere faserverstärkter Kunststoff. Hierzu abzugrenzen sind weiche Dichtmaterialien wie etwa Gummi oder Silikon, die bei Verwendung als Dichtung in sich deformiert werden, um eine ausreichende Dichtwirkung zu erzielen.In a particularly preferred embodiment of the invention, the seal comprises a sealing ring open in the circumferential direction. As a result, sealing rings made of dimensionally stable material can be inserted into the groove. Generally preferred, the sealing ring consists of a hard sealant. Under a hard sealant is understood a material that is not or not visibly elastically deformed in the sealing state. Such a material may be, for example, a metal such as steel, copper or aluminum or else a hard, in particular fiber-reinforced plastic. To delineate this are soft sealing materials such as rubber or silicone, which are deformed in themselves when used as a seal in order to achieve a sufficient sealing effect.

Im Interesse einer hohen Dichtwirkung sind zumindest zwei in axialer Richtung hintereinander angeordnete Dichtungsringe vorgesehen, Besonders bevorzugt sind beide Dichtungsringe in der Nut eingesetzt, so dass eine geringe Bauhöhe erzielt wird. Offene Stöße der Dichtungsringe können dabei im Umfangsrichtung versetzt zueinander orientiert werden, um eine gute Dichtheit auch bei hohen Drücken zu gewährleisten.In the interest of a high sealing effect, at least two sealing rings arranged one behind the other in the axial direction are provided. Particularly preferably, both sealing rings are inserted in the groove, so that a low overall height is achieved. Open shocks of the sealing rings can be oriented offset in the circumferential direction to each other to ensure a good seal even at high pressures.

Zur Verbesserung der Dichtwirkung ist es dabei bevorzugt vorgesehen, dass unter dem Dichtungsring ein elastisches Stützglied angeordnet ist. Ein solches Stützglied kann insbesondere ein umlaufender, in die Nut eingesetzter Ring aus einem elastischen Material sein, zum Beispiel aus einem Elastomer oder aus einem Federblech. Das Stützglied kann an Stelle eines umlaufenden Ringes auch aus mehreren einzelnen elastischen Gliedern bestehen.To improve the sealing effect, it is preferably provided that under the sealing ring, an elastic support member is arranged. Such a support member may in particular be a circumferential ring inserted into the groove from an elastic material, for example an elastomer or a spring plate. The support member may consist of several individual elastic members instead of a circumferential ring.

Eine bevorzugte Ausführungsform des Eintreibgeräts weist ein Gehäuse auf, mit welchem die Brennkammerwand starr verbunden ist. Der Boden stellt dann in dem Eintreibgerät ein bewegtes Teil dar. Eine alternative Ausführungsform des Eintreibgeräts weist ein Gehäuse auf, mit welchem der Boden starr verbunden ist. Die Brennkammerwand stellt dann in dem Eintreibgerät ein bewegtes Teil dar.A preferred embodiment of the tacker has a housing with which the combustion chamber wall is rigidly connected. The floor then constitutes a moving part in the tacker. An alternative embodiment of the tacker has a housing to which the floor is rigidly connected. The combustion chamber wall is then in the tacker a moving part.

Bevorzugt ist der Boden gegenüber der Brennkammerwand so weit verstellbar, dass sich zwischen dem Boden und der Brennkammerwand eine Ein- und/oder Auslassöffnung der Brennkammer für Luft und/oder Brennstoff bildet. Besonders bevorzugt bilden der Boden und die Brennkammerwand ein Ein- und/oder Auslassventil der Brennkammer.Preferably, the bottom is so far adjustable relative to the combustion chamber wall that forms an inlet and / or outlet opening of the combustion chamber for air and / or fuel between the bottom and the combustion chamber wall. Particularly preferably, the bottom and the combustion chamber wall form an inlet and / or outlet valve of the combustion chamber.

Weitere Vorteile und Merkmale der Erfindung ergeben sich aus dem nachfolgend beschriebenen Ausführungsbeispiel sowie aus den abhängigen Ansprüchen.Further advantages and features of the invention will become apparent from the embodiment described below and from the dependent claims.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel der Erfindung beschrieben und anhand der anliegenden Zeichnungen näher erläutert.

Das Eintreibgerät aus Fig. 1 ist ein handgeführtes Gerät, umfassend ein Gehäuse 19 sowie eine Brennkammer 1 mit einer abschnittsweise zylindrischen Brennkammerwand 2, welche starr mit dem Gehäuse 19 verbunden ist. An die Brennkammer 1 grenzt ein Zylinder 3 mit einem darin geführten Eintreibkolben 4 an. Eine Sicherheitsmechanik des Gerätes umfasst eine Aufsetzhülse 5, die auf ein Werkstück (nicht dargestellt) aufgesetzt wird und gegen den Druck einer Feder eingedrückt wird. Nur in diesem Zustand kann ein Eintreibvorgang durch Zünden eines Brenngases in der Brennkammer ausgelöst werden. In der Brennkammer 1 ist zudem eine Wirbelplatte 6 angeordnet, die vor einer Zündung durch die Brennkammer 1 bewegt werden kann.The tacker off Fig. 1 is a hand-held device, comprising a housing 19 and a combustion chamber 1 with a partially cylindrical combustion chamber wall 2, which is rigidly connected to the housing 19. Adjacent to the combustion chamber 1 is a cylinder 3 with a drive piston 4 guided therein. A safety mechanism of the device comprises a Aufsetzhülse 5, which is placed on a workpiece (not shown) and is pressed against the pressure of a spring. Only in this state, a driving operation can be triggered by igniting a fuel gas in the combustion chamber. In the combustion chamber 1, a swirl plate 6 is also arranged, which can be moved by the combustion chamber 1 before ignition.

Ein Boden 7 der Brennkammer 1 ist entlang einer mit der Eintreibrichtung zusammenfallenden Achse bewegbar, so dass das Volumen der Brennkammer veränderlich ist. Der Boden 7 ist hierzu mit einer umlaufenden Dichtung 8 gegenüber der zylindrischen Brennkammerwand 2 abgedichtet. In den Fig. 1 und 2 ist die Dichtung 8 nur schematisch dargestellt. Eine erfindungsgemäße Detailgestaltung der Dichtung 8 ist nur in Fig. 3 detailliert gezeigt.A bottom 7 of the combustion chamber 1 is movable along an axis coincident with the driving direction, so that the volume of the combustion chamber is variable. The bottom 7 is sealed for this purpose with a circumferential seal 8 with respect to the cylindrical combustion chamber wall 2. In the Fig. 1 and 2 the seal 8 is shown only schematically. An inventive detailed design of the seal 8 is only in Fig. 3 shown in detail.

Bei nicht gezeigten Ausführungsbeispielen ist der Boden starr mit dem Gehäuse verbunden und die Brennkammerwand ist als axial bewegbare Hülse ausgebildet. Bei ebenfalls nicht dargestellten Ausführungsbeispielen ist die Brennkammerwand gegenüber dem Boden so weit verstellbar, so dass sich zwischen dem Boden und der Brennkammerwand eine Ein- und/oder Auslassöffnung der Brennkammer für Luft und/oder Brennstoff bildet.In embodiments not shown, the bottom is rigidly connected to the housing and the combustion chamber wall is formed as an axially movable sleeve. In embodiments also not shown, the combustion chamber wall is so far adjustable relative to the ground, so that forms an inlet and / or outlet opening of the combustion chamber for air and / or fuel between the bottom and the combustion chamber wall.

Der Boden 7 kann über eine Stellstange 9 in Richtung der Achse bewegt werden, wobei die Stellstange 9 eine Durchführung in einem vorderen, zweiten Boden der Brennkammer durchgreift. Das Eindrücken der Aufsetzhülse 5 spannt zunächst eine Feder und wirkt auf die Stellstange 9, welche wiederum den Boden 7 verschiebt. Hierdurch wird ein für eine Zündung ausreichendes Volumen der Brennkammer erst aufspannt. Bei dieser Bewegung des Bodens entlang der Brennkammerwand wird regelmäßig kondensiertes Wasser abgestreift. Zur Vermeidung von Schwergängigkeit des Mechanismus sollte möglichst wenig Wasser in den Bereich der Dichtung 8 eindringen und gefrieren. Hierzu weisen der Boden 7, die Brennkammer 1 und die Dichtung 8 besondere Weiterentwicklungen auf, die nachfolgend beschrieben werden.The bottom 7 can be moved via an adjusting rod 9 in the direction of the axis, wherein the adjusting rod 9 passes through a passage in a front, second bottom of the combustion chamber. The impressions of the attachment sleeve 5 initially tensions a spring and acts on the adjustment rod 9, which in turn displaces the base 7. As a result, sufficient for an ignition volume of the combustion chamber is only opened. During this movement of the soil along the combustion chamber wall condensed water is regularly stripped off. To avoid binding of the mechanism, as little water as possible should penetrate into the region of the seal 8 and freeze. For this purpose, the bottom 7, the combustion chamber 1 and the seal 8 special developments, which are described below.

Die Dichtung 8 ist als Satz von zwei in axialer Richtung unmittelbar aufeinander liegenden Dichtungsringen 10, 11 ausgebildet. Beide Dichtungsringe 10, 11 sind in derselben Nut 12 an einer äußeren Umfangswand 7a des Bodens 7 aufgenommen. Die Dichtungsringe 10, 11 bestehen aus einem harten Material, vorliegend einem Stahl. Die Dichtungsringe 10, 11 haben jeweils einen offenen Stoß 13, um in die Nut 12 einsetzbar zu sein. Zudem erlaubt der Stoß ein definiertes Andrücken der Dichtungsringe an die Brennkammerwand. Hierzu ist unterhalb der Dichtungsringe ein elastisches Stützglied 14 in der Nut angeordnet. Bei eingesetzten Dichtungsringen 10, 11 ist das Stützglied 14 in radialer Richtung eingedrückt und federelastisch mit einer Kraft beaufschlagt. Die Stöße 13 der Dichtungsringe 10, 11 sind in Umfangsrichtung versetzt zueinander orientiert. In der Darstellung nach Fig. 3 liegt der Stoß 13 des vorderen Dichtungsrings 11 in der Schnittebene und ist daher sichtbar.The seal 8 is formed as a set of two sealing rings 10, 11 lying directly one above the other in the axial direction. Both seal rings 10, 11 are received in the same groove 12 on an outer peripheral wall 7 a of the bottom 7. The sealing rings 10, 11 are made of a hard material, in the present case a steel. The sealing rings 10, 11 each have an open shock 13 to be inserted into the groove 12. In addition, the impact allows a defined pressing of the sealing rings to the combustion chamber wall. For this purpose, an elastic support member 14 is disposed in the groove below the sealing rings. When using sealing rings 10, 11, the support member 14 is pressed in the radial direction and resiliently acted upon by a force. The joints 13 of the sealing rings 10, 11 are circumferentially offset from each other. In the illustration after Fig. 3 is the shock 13 of the front seal ring 11 in the sectional plane and is therefore visible.

Die Dichtungsringe 10, 11 haben vorliegend einen jeweils L-förmigen Querschnitt und sind spiegelsymmetrisch zu einer Mittelebene der Nut angeordnet. Insbesondere können die Dichtungsringe 10, 11 als gleiche Bauteile ausgeformt sein. Der jeweils eine Schenkel des L-förmigen Querschnitts greift in die Nut 12 ein. Der jeweils andere Schenkel erstreckt sich in axialer Richtung in dem Spalt 15 zwischen der Umfangswand 7a des Bodens 7 und der Brennkammerwand 2. Eine in axialer Richtung jeweils vordere Fläche 10a, 11a der Dichtungsringe 10, 11 ragt jeweils vor eine Abschlussebene E1, E2 der Nut 12. Insbesondere ragt die vordere Fläche 10a, 11a in axialer Richtung auch vor eine jeweilige Abschlussebene A1, A2 des Bodens 2. Ein jeweils radial inneres Ende der vorderen Flächen 10a, 11a hat einen scharfkantigen Abschluss 10b, 11b in Form einer Kante mit einem Winkel von 90°. Die Kante liegt dabei jeweils vor der Abschlussebene A1, A2 des Bodens 2. Ein Krümmungsradius der Kante beträgt bevorzugt weniger als 0,5 mm, insbesondere weniger als 0,2 mm.The sealing rings 10, 11 in the present case have a respective L-shaped cross section and are arranged mirror-symmetrically to a median plane of the groove. In particular, the sealing rings 10, 11 may be formed as the same components. The respective one leg of the L-shaped cross-section engages in the groove 12 a. The respective other leg extends in the axial direction in the gap 15 between the peripheral wall 7a of the bottom 7 and the combustion chamber wall 2. A respective front surface 10a, 11a of the sealing rings 10, 11 protrudes in front of a final plane E1, E2 of the groove in the axial direction 12. In particular, the front surface 10a, 11a in the axial direction also projects in front of a respective termination plane A1, A2 of the bottom 2. A respective radially inner end of the front surfaces 10a, 11a has a sharp-edged end 10b, 11b in the form of an edge at an angle of 90 °. The edge lies in each case before the termination plane A1, A2 of the bottom 2. A radius of curvature of the edge is preferably less than 0.5 mm, in particular less than 0.2 mm.

Um das durch die Bewegung des Bodens abgestreifte Wasser besser abzuführen und einen Wasserstau nebst Eindringen in den Spalt 15 zu vermeiden, ist an dem Boden 7 eine Ausnehmung 16 vorgesehen. Die Ausnehmung 16 ist als ringförmiger Raum ausgeformt, der zwischen dem Boden 7 und einem Anschlagring 17 verbleibt. Bei vollständig aufgespannter Brennkammer ist der Boden 7 an dem Anschlagring 17 abgestützt. Durch Öffnungen 18 kann das abgestreifte Wasser zudem an dem Anschlagring 17 vorbei in andere Gehäusebereiche abfließen.In order to better dissipate the water stripped off by the movement of the soil and to avoid a build-up of water along with penetration into the gap 15, a recess 16 is provided on the bottom 7. The recess 16 is formed as an annular space which remains between the bottom 7 and a stop ring 17. With the combustion chamber fully open, the bottom 7 is supported on the stop ring 17. Through openings 18, the stripped water can also flow past the stop ring 17 in other housing areas.
