Definitions
- the invention relates to a removal tool for removing an opening in a housing wall.
- the starting point for the invention are completely closed electrical empty housings with so-called knock-out areas. These knock-out areas can be knocked out of a prepared housing area with a tool such as a screwdriver.
- the prerequisites for this are a sufficiently small wall thickness and sufficiently brittle housing material properties of the empty electrical housing. Knocking out the knock-out area thus harbors the risk of unwanted damage to the empty electrical housing, the sealing surfaces and fragments remaining inside the housing. Anything can lead to general sealing problems and malfunctions.
- the break edge can have increased sharpness, which can lead to damage to the line insulation when the line is pulled in.
- the freedom of movement for knocking out the knock-out area can be severely restricted, which can result in significant practical problems.
- an improved construction of an anchor dowel which consists primarily of a drill screw rod, an anchor sleeve and a screw nut.
- the pamphlet DE 103 53 617 A1 teaches a method for removing solids from tubes of a shell and tube heat exchanger.
- the object is achieved by a removal tool for removing an opening in a housing wall, with a removal device which is arranged on an end section of the removal tool, and a thread for screwing the removal tool into a threaded connector in or on a housing wall to make an opening in a housing wall.
- the removal tool In order to screw the removal tool into the housing wall in a controlled manner and with appropriate force and to simplify the removal of the opening for a user of the removal tool, the removal tool has an actuation area for driving the removal tool by means of a tool.
- Any manually operable tool such as a screwdriver, as well as a cordless screwdriver or a drill with a corresponding adapter, can be used as a tool.
- the actuation area is designed to be radially or axially drivable from the inside or outside with a socket, ring or open-end wrench, screwdriver, Allen key or a cylindrical pin-like tool. This enables in particular that no special tool has to be available for driving the removal tool. Simple and commonly used tools can therefore be used.
- the actuation area has lateral openings in order to radially surround the removal tool with a rod-shaped tool to drive.
- the technical advantage is achieved that the actuation of the removal tool can additionally be simplified by radially inserting a rod-shaped tool. This could be of particular importance, for example, if the thread of the removal tool is fully screwed into the threaded connector of the housing wall and the removal of the opening involves increased effort or the axial space conditions for the use of frontal drive tools are not available.
- a screwdriver can be inserted into the side opening of the actuation area in order to enable easier removal with a larger lever or, in the case of axially limited space, better screwing in and unscrewing.
- the lateral openings extend completely through the actuation area of the removal tool. As a result, the tool can be guided completely through the removal tool, thus ensuring that the tool does not slip.
- the front-side cutting device is designed as a multiple cutting edge. This increases the service life of the separating device and increases the maintenance intervals.
- the front-side separating device is formed by several penetrating cylinder contours.
- the cutting device In order to implement the production and regrinding of the cutting device in a particularly simple and reliable manner, the cutting device has two cylinder contours which are arranged rotated by 90 ° with respect to one another.
- the cutting device comprises a wave-like contour.
- the removal device comprises a sawtooth-shaped contour.
- the cutting device comprises a punch-iron-like cylinder contour for punching out the opening.
- At least the separating device is made of metal.
- Metal offers particularly suitable properties for the purpose according to the invention.
- a metallic separating device can be produced in a simple manner, but it can also be reground very easily.
- the removal tool is designed in one piece.
- the technical advantage is achieved that a constant or standardized actuation area can be combined with different thread sizes or with different variants of separating devices.
- the actuation area and the removal tool are designed to be connectable by means of a plug connection.
- This connector can be designed in any conceivable way. It is only essential that the necessary torque can be transmitted through the tool to the actuation area and from the actuation area to the cutting device. This enables the cutting device to be exchangeable and exchanged if necessary. Reasons for this can be that different cutting geometries or other cutting sizes have to be used for other housing materials or a worn cutting device has to be replaced with a new cutting device.
- the object is achieved by an assembly device for cutting out an opening in a housing wall, with a removal tool according to one of the preceding embodiments and a housing wall with a threaded connector, the threaded connector having an internal thread which corresponds to the thread of the removal tool .
- the object is achieved by a method for cutting out an opening in a housing wall with a removal tool according to one of the preceding embodiments, with the provision of a threaded connector on a housing wall, the screwing of a removal tool into the threaded connector, and the removal the opening in the housing wall through the cutting device, which is arranged on the frontal section of the cutting tool.
- This results in a damage-free and chip-free production on the housing wall.
- simple operation and easy accessibility are achieved in the case of limited space, with no need to knock out housing areas. As a consequence, the risk of damage to the housing wall is reduced and sealing problems are prevented.
- FIG. 11 shows a perspective illustration of a removal tool 100.

Description
Die Erfindung betrifft ein Austrennwerkzeug zum Austrennen einer Öffnung in eine Gehäusewandung.The invention relates to a removal tool for removing an opening in a housing wall.
Ausgangspunkt für die Erfindung sind vollständig geschlossene Elektro-Leergehäuse mit sogenannten Knock out - Bereichen. Diese Knock out - Bereiche können mit einem Werkzeug, wie beispielsweise einem Schraubendreher, aus einem vorbereiteten Gehäusebereich herausgeschlagen werden. Voraussetzungen hierfür sind eine hinreichend geringe Wandstärke und hinreichend spröde Gehäusewerkstoffeigenschaften des Elektro-Leergehäuses. Das Herausschlagen des Knock out - Bereichs birgt somit das Risiko von ungewollten Beschädigungen des Elektro-Leergehäuses, der Dichtflächen und vom Verbleib von Bruchstücken im Gehäuseinneren. Alles kann zu allgemeinen Dichtungsproblemen und Störungen führen. Des Weiteren kann die Bruchkante eine erhöhte Scharfkantigkeit aufweisen, was beim Einziehen der Leitung zur Verletzung von Leitungsisolationen führen kann. Zudem kann der Bewegungsspielraum zum Herausschlagen des Knock out - Bereichs stark eingeschränkt sein, wodurch sich deutliche praktische Probleme ergeben können.The starting point for the invention are completely closed electrical empty housings with so-called knock-out areas. These knock-out areas can be knocked out of a prepared housing area with a tool such as a screwdriver. The prerequisites for this are a sufficiently small wall thickness and sufficiently brittle housing material properties of the empty electrical housing. Knocking out the knock-out area thus harbors the risk of unwanted damage to the empty electrical housing, the sealing surfaces and fragments remaining inside the housing. Anything can lead to general sealing problems and malfunctions. Furthermore, the break edge can have increased sharpness, which can lead to damage to the line insulation when the line is pulled in. In addition, the freedom of movement for knocking out the knock-out area can be severely restricted, which can result in significant practical problems.

Es ist die Aufgabe der vorliegenden Erfindung die Nachteile aus dem Stand der Technik zu überwinden und ein verbessertes Austrennwerkzeug zum Austrennen einer Öffnung in eine Gehäusewandung bereitzustellen.It is the object of the present invention to overcome the disadvantages of the prior art and to provide an improved removal tool for removing an opening in a housing wall.
Diese Aufgabe wird durch den Gegenstand mit den Merkmalen nach den unabhängigen Ansprüchen gelöst. Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Figuren, der Beschreibung und der abhängigen Ansprüche.This object is achieved by the subject matter with the features according to the independent claims. Advantageous embodiments of the invention are the subject matter of the figures, the description and the dependent claims.
Gemäß einem Aspekt der Erfindung wird die Aufgabe durch ein Austrennwerkzeug zum Austrennen einer Öffnung in eine Gehäusewandung gelöst, mit einer Austrennvorrichtung, welche an einem stirnseitigen Abschnitt des Austrennwerkzeugs angeordnet ist, und einem Gewinde zum Einschrauben des Austrennwerkzeugs in einen Gewindestutzen in oder an einer Gehäusewandung um eine Öffnung in eine Gehäusewandung einzubringen. Dadurch wird beispielsweise der technische Vorteil erreicht, dass ein beschädigungsfreies und spanfreies Arbeiten an der Gehäusewandung möglich ist. Hierbei wird zusätzlich eine einfache Bedienung sowie eine einfache Zugänglichkeit bei eingeschränkten Platzverhältnissen realisiert, wobei kein Herausschlagen von Gehäusebereichen notwendig ist. In der Konsequenz wird das Risiko von Beschädigungen der Gehäusewandung reduziert und Dichtungsprobleme können verhindert werden.According to one aspect of the invention, the object is achieved by a removal tool for removing an opening in a housing wall, with a removal device which is arranged on an end section of the removal tool, and a thread for screwing the removal tool into a threaded connector in or on a housing wall to make an opening in a housing wall. As a result, for example, the technical advantage is achieved that damage-free and chip-free work on the housing wall is possible. In this case, simple operation and easy accessibility are also implemented in the case of limited space, with no need to knock out housing areas. As a consequence, the risk of damage to the housing wall is reduced and sealing problems can be prevented.
Um das Austrennwerkzeug kontrollierter und mit angemessenem Kraftaufwand in die Gehäusewandung einzudrehen und um das Austrennen der Öffnung für einen Nutzer des Austrennwerkzeugs zu vereinfachen, weist das Austrennwerkzeug einen Betätigungsbereich zum Antreiben des Austrennwerkzeugs mittels eines Werkzeugs auf. Als Werkzeug kann hier sowohl jedes manuell betätigbare Werkzeug, wie beispielsweise ein Schraubendreher, als auch ein Akkuschrauber oder eine Bohrmaschine mit entsprechendem Adapter genutzt werden.In order to screw the removal tool into the housing wall in a controlled manner and with appropriate force and to simplify the removal of the opening for a user of the removal tool, the removal tool has an actuation area for driving the removal tool by means of a tool. Any manually operable tool, such as a screwdriver, as well as a cordless screwdriver or a drill with a corresponding adapter, can be used as a tool.
Um den Betätigungsbereich möglichst mit standardisierten Werkzeugen kompatibel zu gestalten, ist der Betätigungsbereich mit einem Steck-, Ring- oder Gabelschlüssel, Schraubendreher, Innensechskantschlüssel oder einem zylinderstiftartigem Werkzeug von innen oder von außen radial oder axial antreibbar ausgebildet. Dies ermöglicht insbesondere, dass zum Antreiben des Austrennwerkzeugs kein spezielles Werkzeug verfügbar sein muss. Es lässt sich somit auf einfache und allgemein verwendete Werkzeuge zurückgreifen.In order to make the actuation area as compatible as possible with standardized tools, the actuation area is designed to be radially or axially drivable from the inside or outside with a socket, ring or open-end wrench, screwdriver, Allen key or a cylindrical pin-like tool. This enables in particular that no special tool has to be available for driving the removal tool. Simple and commonly used tools can therefore be used.
Gemäß einer bevorzugten Ausführungsform, weist der Betätigungsbereich seitliche Öffnungen auf, um das Austrennwerkzeug mit einem stabförmigen Werkzeug radial anzutreiben. Dadurch wird beispielsweise der technische Vorteil erreicht, dass das Betätigen des Austrennwerkzeugs zusätzlich durch radiales Einstecken eines stabförmigen Werkzeugs vereinfacht werden kann. Dies könnte beispielsweise dann von besonderer Bedeutung sein, wenn das Gewinde des Austrennwerkzeugs vollständig in den Gewindestutzen der Gehäusewandung eingedreht ist und das Austrennen der Öffnung mit einem erhöhten Kraftaufwand einhergeht oder die axialen Platzverhältnisse für die Verwendung von stirnseitigen Antriebswerkzeugen nicht vorhanden sind. Hier kann ein Schraubendreher in die seitliche Öffnung des Betätigungsbereichs eingebracht werden, um dann mit einem größeren Hebel ein vereinfachtes Austrennen oder bei axial begrenzten Platzverhältnissen ein besseres Ein- und Ausschrauben zu ermöglichen.According to a preferred embodiment, the actuation area has lateral openings in order to radially surround the removal tool with a rod-shaped tool to drive. As a result, for example, the technical advantage is achieved that the actuation of the removal tool can additionally be simplified by radially inserting a rod-shaped tool. This could be of particular importance, for example, if the thread of the removal tool is fully screwed into the threaded connector of the housing wall and the removal of the opening involves increased effort or the axial space conditions for the use of frontal drive tools are not available. Here a screwdriver can be inserted into the side opening of the actuation area in order to enable easier removal with a larger lever or, in the case of axially limited space, better screwing in and unscrewing.
Um das Betätigen des Austrennwerkzeugs durch radiales Einstecken eines stabförmigen Werkzeugs zusätzlich zu vereinfachen, erstrecken sich die seitlichen Öffnungen vollständig durch den Betätigungsbereich des Austrennwerkzeugs hindurch. Dadurch kann das Werkzeug vollständig durch das Austrennwerkzeug hindurchgeführt und somit ein Abrutschen des Werkzeugs sichergestellt werden.In order to additionally simplify the actuation of the removal tool by radially inserting a rod-shaped tool, the lateral openings extend completely through the actuation area of the removal tool. As a result, the tool can be guided completely through the removal tool, thus ensuring that the tool does not slip.
Um die Zuverlässigkeit der Austrennvorrichtung zu verbessern, ist die stirnseitige Austrennvorrichtung als Mehrfachschneide ausgebildet. Dies erhöht die Lebensdauer der Austrennvorrichtung und lässt die Wartungsintervalle größer werden.In order to improve the reliability of the cutting device, the front-side cutting device is designed as a multiple cutting edge. This increases the service life of the separating device and increases the maintenance intervals.
Nach einer weiteren bevorzugten Ausführungsform, ist die stirnseitige Austrennvorrichtung durch mehrere sich durchdringende Zylinderkonturen ausgebildet. Dadurch wird beispielsweise der technische Vorteil erreicht, dass das Austrennwerkzeug besonders einfach herzustellen ist.
Um die Herstellung und ein Nachschleifen der Austrennvorrichtung besonders einfach und zuverlässig zu realisieren, weist die Austrennvorrichtung zwei Zylinderkonturen auf, die zueinander um 90° gedreht angeordnet sind.According to a further preferred embodiment, the front-side separating device is formed by several penetrating cylinder contours. This has the technical advantage, for example, that the removal tool is particularly easy to manufacture.
In order to implement the production and regrinding of the cutting device in a particularly simple and reliable manner, the cutting device has two cylinder contours which are arranged rotated by 90 ° with respect to one another.
Um ein spanfreies und splitterfreies Austrennen einer Öffnung zu gewährleisten, umfasst die Austrennvorrichtung eine wellenartige Kontur.In order to ensure a chip-free and splinter-free cutting out of an opening, the cutting device comprises a wave-like contour.
Um das Austrennwerkzeug auch für besonders harte Gehäusewandungen auszubilden, umfasst die Austrennvorrichtung eine sägezahnförmige Kontur. In einer alternativen Ausführungsform umfasst die Austrennvorrichtung eine locheisenartige Zylinderkontur zum Ausstanzen der Öffnung.In order to design the removal tool for particularly hard housing walls, the removal device comprises a sawtooth-shaped contour. In an alternative Embodiment, the cutting device comprises a punch-iron-like cylinder contour for punching out the opening.
Gemäß einer weiteren besonders bevorzugten Ausführungsform, ist zumindest die Austrennvorrichtung aus Metall ausgebildet. Metall bietet für den erfindungsgemäßen Anwendungszweck besonders geeignete Eigenschaften mit sich. So kann eine metallische Austrennvorrichtung einfach hergestellt aber auch sehr leicht nachgeschliffen werden. Alternativ ist es jedoch ebenfalls denkbar die Austrennvorrichtung oder die Austrennvorrichtung aus einem keramischen Material oder einem besonders harten Kunststoff herzustellen.According to a further particularly preferred embodiment, at least the separating device is made of metal. Metal offers particularly suitable properties for the purpose according to the invention. In this way, a metallic separating device can be produced in a simple manner, but it can also be reground very easily. Alternatively, however, it is also conceivable to manufacture the cutting device or the cutting device from a ceramic material or a particularly hard plastic.
Um den Herstellungsaufwand und die Herstellungskosten gering zu halten, ist das Austrennwerkzeug einstückig ausgebildet. Alternativ ist es jedoch ebenso denkbar, das Austrennwerkzeug modular auszubilden, um den Betätigungsbereich von dem Austrennwerkzeug zu trennen. Dadurch wird beispielsweise der technische Vorteil erreicht, dass ein gleichbleibender oder standardisierter Betätigungsbereich mit unterschiedlichen Gewindegrößen oder mit unterschiedlichen Varianten von Austrennvorrichtungen kombinierbar ist. Somit kann mit einem gleichbleibenden Betätigungsbereich und somit mit einem gleichbleibenden Werkzeug unterschiedliche Austrennwerkzeuge mit verschiedenen Varianten von Gewindegröße und Austrennvorrichtung betätigt werden.In order to keep the manufacturing effort and the manufacturing costs low, the removal tool is designed in one piece. Alternatively, however, it is also conceivable to design the removal tool in a modular manner in order to separate the actuation area from the removal tool. In this way, for example, the technical advantage is achieved that a constant or standardized actuation area can be combined with different thread sizes or with different variants of separating devices. Thus, with a constant actuation area and thus with a constant tool, different removal tools with different variants of thread size and removal device can be actuated.
Gemäß einer besonders bevorzugten Ausführungsform, sind der Betätigungsbereich und das Austrennwerkzeug mittels einer Steckverbindung verbindbar ausgebildet. Diese Steckverbindung kann auf jede denkbare Art ausgebildet sein. Wesentlich ist nur, dass das notwendige Drehmoment durch das Werkzeug auf den Betätigungsbereich und von dem Betätigungsbereich auf die Austrennvorrichtung übertragbar ist. Das ermöglicht, dass die Austrennvorrichtung wechselbar ist und bei Bedarf ausgetauscht werden kann. Gründe dafür können sein, dass andere Austrenngeometrien oder andere Austrenngrößen für andere Gehäusewerkstoffe eingesetzt werden müssen oder eine verschlissene Austrennvorrichtung gegen eine neue Austrennvorrichtung ausgetauscht werden muss.According to a particularly preferred embodiment, the actuation area and the removal tool are designed to be connectable by means of a plug connection. This connector can be designed in any conceivable way. It is only essential that the necessary torque can be transmitted through the tool to the actuation area and from the actuation area to the cutting device. This enables the cutting device to be exchangeable and exchanged if necessary. Reasons for this can be that different cutting geometries or other cutting sizes have to be used for other housing materials or a worn cutting device has to be replaced with a new cutting device.
Gemäß einem weiteren Aspekt der Erfindung wird die Aufgabe durch eine Montagevorrichtung zum Austrennen einer Öffnung in eine Gehäusewandung, mit einem Austrennwerkzeug gemäß einer der vorangehenden Ausführungsformen und einer Gehäusewandung mit einem Gewindestutzen gelöst, wobei der Gewindestutzen ein Innengewinde aufweist, welches mit dem Gewinde des Austrennwerkzeugs korrespondiert.According to a further aspect of the invention, the object is achieved by an assembly device for cutting out an opening in a housing wall, with a removal tool according to one of the preceding embodiments and a housing wall with a threaded connector, the threaded connector having an internal thread which corresponds to the thread of the removal tool .
Gemäß einem noch weiteren Aspekt der Erfindung wird die Aufgabe durch ein Verfahren zum Austrennen einer Öffnung in eine Gehäusewandung mit einem Austrennwerkzeug gemäß einem der vorangehenden Ausführungsformen gelöst, mit dem Bereitstellen eines Gewindestutzens an einer Gehäusewandung, dem Eindrehen eines Austrennwerkzeugs in den Gewindestutzen, und dem Austrennen der Öffnung in die Gehäusewandung durch die Austrennvorrichtung, welche an dem stirnseitigen Abschnitt des Austrennwerkzeugs angeordnet ist. Dadurch erfolgt ein beschädigungsfreies und spanfreies Herstellen an der Gehäusewandung. Zusätzlich wird eine einfache Bedienung sowie eine einfache Zugänglichkeit bei eingeschränkten Platzverhältnissen realisiert, wobei kein Herausschlagen von Gehäusebereichen notwendig ist. In der Konsequenz wird das Risiko von Beschädigungen der Gehäusewandung reduziert und Dichtungsprobleme werden verhindert.According to yet another aspect of the invention, the object is achieved by a method for cutting out an opening in a housing wall with a removal tool according to one of the preceding embodiments, with the provision of a threaded connector on a housing wall, the screwing of a removal tool into the threaded connector, and the removal the opening in the housing wall through the cutting device, which is arranged on the frontal section of the cutting tool. This results in a damage-free and chip-free production on the housing wall. In addition, simple operation and easy accessibility are achieved in the case of limited space, with no need to knock out housing areas. As a consequence, the risk of damage to the housing wall is reduced and sealing problems are prevented.
