Description

Die Erfindung betrifft eine Vorrichtung zum Anbringen von Löchern in zueinander geneigten Flächen eines Blechteils, wie Trapezblechen und dergleichen.The invention relates to a device for mounting holes in mutually inclined surfaces of a sheet metal part, such as trapezoidal sheets and the like.

Trapezbleche sind im Querschnitt gekantete Profilbleche. Sie werden vielfach für Dach-, Decken- und Wandkonstruktionen verwendet.Trapezoidal sheets are profile sheets folded in cross section. They are widely used for roof, ceiling and wall constructions.

Bei der Montage von Bauteilen an Trapezdächern müssen häufig die Trapezdächer gelocht werden, um den Trapezhalter an das Trapezdach mit einer Schraube zu befestigen. Die Herstellung derartiger Löcher ist wegen der teilweise erschwerten Zugänglichkeit durch andere Bauteile oder im Randbereich durch Wände vielmals mit herkömmlichen Lochzangen nicht möglich.When mounting components to trapezoidal roofs, the trapezoidal roofs often need to be perforated to secure the trapezoidal support to the trapezoidal roof with a screw. The production of such holes is not possible because of the sometimes difficult accessibility by other components or in the edge region through walls many times with conventional hole pliers.

Bei herkömmlichen Lochzangen ist nicht nur der hohe Platzbedarf nachteilig, auch der hohe manuelle Kraftaufwand, besonders bei dicken Materialstärken des Trapezdaches auf Grund schwerer Dachlasten.In conventional punching pliers, not only the high space requirement is disadvantageous, also the high manual effort, especially with thick material thicknesses of the trapezoidal roof due to heavy roof loads.

In DE 20 2004 006 600 U1 ist eine handbetätigbare Lochzange beschrieben, die zwei über ein Drehgelenk verbundene schwenkbare Hebel aufweist, deren hintere Enden als Handgriffe ausgebildet sind, und am vorderen Ende eines Hebels eine einsetzbare Matrize und am vorderen Ende des anderen Hebels ein einsetzbarer Lochstempel vorhanden ist.In DE 20 2004 006 600 U1 is a hand-operated punching pliers described having two pivotally connected via a pivot lever whose rear ends are formed as handles, and at the front end of a lever an insertable die and at the front end of the other lever an insertable punch is present.

Aus DE 35 21 132 A1 ist eine Stanzvorrichtung zum Bearbeiten von winklig zueinander angeordneten Profilabschnitten bekannt, in die Löcher in einem Arbeitsgang dadurch eingebracht werden, dass zwei Stanzwerkzeuge in einem Stanzkopf winklig zueinander angeordnet sind, wobei die Stanzwerkzeige in Richtung der Profilabschnitte mittels eines Druckkolbens angetrieben werden. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangsgenannten Art zu schaffen, die ohne hohen Kraftaufwand bedient werden kann und bei kompakter Ausbildung eine exakte Lochung der Blechteile ermöglicht.Out DE 35 21 132 A1 is a punching device for editing of angularly arranged profile sections are known, are introduced into the holes in a single operation characterized in that two punching tools are arranged in a punching head at an angle to each other, wherein the punching tool display are driven in the direction of the profile sections by means of a pressure piston. The invention has for its object to provide a device of the type mentioned above, which can be operated without much effort and with a compact design allows accurate perforation of the sheet metal parts.

Die Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen.The object is achieved by a device having the features specified in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Vorrichtung zum Anbringen von Löchern in Blechteilen mit zueinander geneigten Flächen verwendet für die Lochung zwei zweiarmige Hebel. An einem Hebelarm jedes Hebels ist ein Lochstempel angeordnet, mit dem das Blechteil an der erforderlichen Position gelocht werden kann. An dem jeweils anderen Hebelarm wird die Betätigungskraft zur Ausführung einer Schwenkbewegung eingeleitet. Jeder Hebel ist mittels eines Drehgelenks mit einem Träger verbunden. Aufgrund der zweiarmigen Ausbildung der Hebel zeichnet sich die Vorrichtung durch eine kompakte Gestaltung aus.The inventive device for mounting holes in sheet metal parts with mutually inclined surfaces used for the hole two two-armed lever. On a lever arm of each lever, a punch is arranged, with which the sheet metal part can be punched in the required position. At the other lever arm, the actuating force is initiated to perform a pivoting movement. Each lever is connected by means of a rotary joint with a carrier. Due to the two-armed design of the lever, the device is characterized by a compact design.

Bei einer vorteilhaften Ausgestaltung sind an dem Träger zwei Lagerbolzen angeordnet. Die Lagerbolzen ragen in an den Hebeln angebrachte Bohrungen hinein. Die Lagerbolzen definieren damit die Drehachse für die Schwenkbewegung der Hebel.In an advantageous embodiment, two bearing bolts are arranged on the carrier. The bearing bolts protrude into holes mounted on the levers. The bearing pins thus define the axis of rotation for the pivotal movement of the lever.

Eine weitere vorteilhafte Ausgestaltung sieht vor, dass am Träger eine Aufnahme zur Verbindung der Vorrichtung zum Lochen mit einer Antriebsvorrichtung angeordnet ist.A further advantageous embodiment provides that on the carrier a receptacle for connecting the device for punching with a drive device is arranged.

Bei einer weiteren vorteilhaften Ausgestaltung ist zwischen den Hebeln eine als Biegefeder ausgestaltete Feder angeordnet. Die Feder drückt die Hebelarme der Hebel, die für die Krafteinleitung vorgesehen sind, auseinander und damit die Hebelarme, an denen die Lochstempel befestigt sind zusammen Die Feder ist so bemessen, dass sie ohne Kraftanstrengung von Hand überwunden werden kann. Damit ist es möglich, die Vorrichtung in einfacher Weise an der Sollstelle für die vorzunehmende Lochung zu positionieren. Die Vorrichtung verbleibt dann nach dem Loslassen an der abgesetzten Position.In a further advantageous embodiment, a spring configured as a bending spring is arranged between the levers. The spring pushes the levers of the lever, which are provided for the introduction of force, apart and thus the lever arms to which the punches are attached together The spring is so measured that it can be overcome by hand without effort. This makes it possible to position the device in a simple manner at the desired location for the hole to be made. The device then remains after releasing at the remote position.

Eine weitere Ausgestaltung entsteht dadurch, dass an Innenkonturen der Betätigungsarme eine Antriebvorrichtung angreifen kann, mit der die Betätigungsarme gegeneinander schwenkbar sind. Mit der Antriebsvorrichtung werden die Schwenkarme auseinander gepresst und damit die Hebelarme, an denen die Lochstempel angebracht sind, zueinander bewegt, sodass die Lochstempel durch das Werkstück dringen und die gewünschten Lochungen erzeugen.A further embodiment arises from the fact that on inner contours of the actuating arms can engage a drive device with which the actuating arms are pivotable relative to each other. With the drive device, the pivot arms are pressed apart and thus the lever arms to which the punches are attached to each other moves so that the punches penetrate through the workpiece and produce the desired perforations.

Das Auseinanderbewegen der Hebelarme erfolgt vorteilhaft mit einem Schiebeelement, das an der Antriebsvorrichtung angebracht ist und in Innenkonturen der Betätigungsarme gepresst wird. Zweckmäßigerweise sind die Innenkonturen der Betätigungsarme an korrespondierende Flächen eines Schiebeelementes der Antriebvorrichtung angepasst.The moving apart of the lever arms is advantageously carried out with a sliding element, which is mounted on the drive device and is pressed into inner contours of the actuating arms. Conveniently, the inner contours of the actuating arms are adapted to corresponding surfaces of a sliding element of the drive device.

Als Antriebsvorrichtung dient vorzugsweise ein Elektrowerkzeug, welches das Schiebeelement mechanisch, pneumatisch oder hydraulisch antreibt.As a drive device is preferably a power tool, which drives the sliding element mechanically, pneumatically or hydraulically.

Eine vorteilhafte Ausführung hierfür sieht vor, dass das Schiebeelement als eine Druckrollen tragende Stange ausgebildet ist, wobei die Druckrollen auf schräge Innenkonturen der Betätigungsarme laufen.An advantageous embodiment for this provides that the sliding element is designed as a pressure rollers supporting rod, wherein the pressure rollers run on inclined inner contours of the actuating arms.
