Description

Die Erfindung betrifft ein Schneidmesser für ein Schneidwerkzeug zum Durchtrennen von Klebewulsten an Fensterscheiben von Fahrzeugen, mit einem U-förmig gewinkelten Querschnitt, umfassend einen ersten als Befestigungsteil ausgebildeten Schenkel mit einer Aufnahmeöffnung zur Befestigung an einem Oszillationsantrieb, sowie einen zweiten Schenkel, der als Schneidteil ausgebildet ist und über einen Zwischensteg mit dem Befestigungsteil des Schneidmessers verbunden ist, wobei der Zwischensteg und das Schneidteil so geformt sind, daß zwischen dem Mittelpunkt der Aufnahmeöffnung und zumindest einer Schneide in radialer Richtung ein Abstand besteht. The invention relates to a cutting knife for a cutting tool for cutting adhesive beads on window panes from Vehicles, with a U-shaped angled cross section, comprising a first leg designed as a fastening part with a receiving opening for attachment to an oscillation drive, and a second leg, which acts as a cutting part is formed and via an intermediate web with the fastening part of the cutting knife is connected, the intermediate web and the cutting part are shaped so that between the center the receiving opening and at least one cutting edge in radial direction there is a distance.

Derartige U-förmig gewinkelte Schneidmesser sind beispielsweise aus der DE 33 24 676 C1 oder aus der EP 0 141 035 B1 bekannt, wobei erstere ein sichelförmig gekrümmtes Schneidteil offenbart, das in bezug auf die Einspannstelle konvex gekrümmt ist, während letztere ein sichelförmig gekrümmtes Schneidteil offenbart, das in bezug auf die Einspannstelle konkav gekrümmt ist.Such U-shaped angled cutting knives are, for example known from DE 33 24 676 C1 or from EP 0 141 035 B1, the former revealing a crescent-shaped cutting part, which is convexly curved with respect to the clamping point, while the latter reveals a crescent-shaped cutting part, which is concavely curved with respect to the clamping point.

Ferner ist aus der EP 0 369 390 A2 ein Schneidmesser mit einem gerade gerichteten Schneidteil bekannt.Furthermore, EP 0 369 390 A2 describes a cutting knife with a straight cutting part known.

Derartige Schneidmesser dienen zum Austrennen von Fensterscheiben, die an Kraftfahrzeugen mittels eines Klebewulstes verklebt sind. Hierbei kann es sich beispielsweise um eine Windschutzscheibe handeln, die auf die A-Säule eines Kraftfahrzeuges mittels eines vollständig umlaufenden Klebewulstes verklebt ist. Der Klebewulst ist hierbei zwischen den Karosserieflansch und der dem Fahrzeuginneren zugewandten Seite der Fensterscheibe durchgehend aufgetragen und besteht meist aus einem besonderen Polyurethan. Derartig verklebte Windschutzscheiben verleihen dem Fahrzeug zusätzlich eine verbesserte mechanische Stabilität der Fahrgastzelle. Es versteht sich, daß aus diesem Grunde der Klebewulst aus einem besonders zähen und widerstandsfähigen Material bestehen muß, das dem Austrennen der Windschutzscheibe einen hohen Widerstand entgegensetzt. Je nach verwendetem Klebematerial kann der Klebewulst auch eine gewisse Porosität aufweisen und insbesondere eine derartige Zähigkeit besitzen, daß ein normales Durchtrennen auch unter Wirkung des Oszillationsantriebes, der in der Regel mit hoher Frequenz in der Größenordnung von etwa 5.000 bis 25.000 Oszillationen pro Minute und mit kleinem Verschwenkwinkel zwischen etwa 0,5 und 5° oszilliert, nur schwer möglich ist. Such cutting knives are used to remove window panes, glued to motor vehicles by means of an adhesive bead are. This can be a windshield, for example act on the A pillar of a motor vehicle a completely circumferential adhesive bead is glued. The adhesive bead is between the body flange and the side of the window pane facing the vehicle interior applied throughout and usually consists of a special one Polyurethane. Give windshields glued in this way the vehicle also has improved mechanical stability the passenger compartment. It is understood that for this reason the Adhesive bead made of a particularly tough and resistant material must exist, which is the removal of the windshield opposes a high resistance. Depending on the adhesive material used the adhesive bead can also have a certain porosity and in particular have such toughness that normal cutting even under the effect of the oscillation drive, which is usually of a high frequency in the order of magnitude from about 5,000 to 25,000 oscillations per minute and oscillates with a small swivel angle between about 0.5 and 5 °, is difficult.

Die Aufgabe der Erfindung besteht demnach darin, ein Schneidmesser gemäß der eingangs genannten Art derart zu verbessern, daß auch Klebewulste, die aus einem besonders zähen und nachgiebigen Material bestehen, mit relativ geringem Kraftaufwand durchtrennt werden können.The object of the invention is therefore a cutting knife to improve in accordance with the type mentioned at the beginning, that also adhesive beads that are made of a particularly tough and compliant Material exist with relatively little effort can be severed.

Diese Aufgabe wird bei einem Schneidmesser gemäß Anspruch 1 gelöst.This object is achieved with a cutting knife according to claim 1 solved.

Es wurde nämlich festgestellt, daß dadurch, daß sich das Schneidteil vom Übergang zum Zwischensteg aus nach außen hin zunächst verbreitert, eine Art Hackeffekt auftritt, durch den ein Durchtrennen von seit neuestem zum Einsatz kommenden besonders zähen Materialien erleichtert wird.It was found that the fact that Cutting part from the transition to the intermediate web outwards initially broadened, a kind of chopping effect occurs, through which cutting through the most recently used especially tough materials is made easier.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen unter Schutz gestellt.Advantageous developments of the invention are in the subclaims put under protection.

Gemäß einer ersten Weiterbildung der Erfindung weist das Schneidteil eine erste, der Aufnahmeöffnung zugewandte und in bezug auf diese konvex gekrümmte Kante auf, sowie eine zweite, der Aufnahmeöffnung abgewandte und in bezug auf diese konkav gekrümmte Kante, wobei zumindest eine der Kanten als Schneide ausgebildet ist. According to a first development of the invention, this Cutting part a first, facing the receiving opening and in with respect to this convexly curved edge, and a second, facing away from the receiving opening and concave with respect to this curved edge, with at least one of the edges as a cutting edge is trained.

Gemäß einem weiteren Merkmal der Erfindung weist das Schneidteil eine erste, der Aufnahmeöffnung zugewandte und gerade gerichtete oder in bezug auf diese konkav gekrümmte Kante auf, sowie eine zweite der Aufnahmeöffnung abgewandte und in bezug auf diese konkav gekrümmte Kante, wobei mindestens eine der Kanten als Schneide ausgebildet ist.According to a further feature of the invention, the cutting part a first, facing the receiving opening and directed straight or with respect to this concave curved edge, and a second, facing away from the receiving opening on this concave curved edge, with at least one of the Edges is designed as a cutting edge.

Gemäß einer weiteren Ausführung der Erfindung weist das Schneidteil eine erste, der Aufnahmeöffnung zugewandte und in bezug auf diese konvex gekrümmte Kante auf, sowie eine zweite, der Aufnahmeöffnung abgewandte Kante auf, die gerade gerichtet ist oder in bezug auf die Aufnahmeöffnung konvex gekrümmt ist, wobei mindestens eine der Kanten als Schneide ausgebildet ist.According to a further embodiment of the invention, this Cutting part a first, facing the receiving opening and in with respect to this convexly curved edge, and a second, edge facing away from the receiving opening, which is directed straight is or is convexly curved with respect to the receiving opening, wherein at least one of the edges is designed as a cutting edge.

Gemäß einer weiteren Ausgestaltung der Erfindung ist das Schneidteil so geformt, daß sich der radiale Abstand zum Mittelpunkt der Aufnahmeöffnung vom Übergang aus zum äußeren Ende hin vergrößert.According to a further embodiment of the invention, this is Cutting part shaped so that the radial distance from the center the receiving opening from the transition to the outer end enlarged towards.

Diese Maßnahme trägt dazu bei, daß der Oszillationshub selbst zur Schneidwirkung ausgenutzt wird, da sich mit jedem Oszillationshub das Schneidteil weiter in das zu durchtrennende Material einschneidet.This measure contributes to the fact that the oscillation stroke itself is used for the cutting effect, since with each oscillation stroke the cutting part further into the material to be cut cuts.

Gemäß einem weiteren Merkmal der Erfindung weist das Schneidteil zwei an seinem äußeren Ende zu einer Spitze zusammenlaufende Schneiden auf.According to a further feature of the invention, the cutting part two converging to a point at its outer end Cutting on.

Dadurch wird das Einstechen des Schneidmessers durch den Klebewulst beim Beginn des Austrennvorgangs erleichtert. The sticking of the cutting knife through the adhesive bead is thereby relieved at the start of the removal process.

Gemäß einer weiteren Ausführung der Erfindung weist das Schneidteil an seiner der Aufnahmeöffnung abgewandten Seite eine Schneide auf und an seiner der Aufnahmeöffnung zugewandten Seite eine Kante, die als stumpfer Rücken ausgebildet ist.According to a further embodiment of the invention, this Cutting part on its side facing away from the receiving opening a cutting edge on and on its facing the receiving opening Side an edge, which is designed as a blunt back.

Diese Maßnahme führt dazu, daß das Schneidteil insgesamt eine größere Masse aufweist, wodurch die kinetische Energie eines Oszillationshubes vergrößert wird, was ein Durchtrennen von besonders zähen oder auch porösen Materialien erleichtert.This measure leads to a total of one cutting part has greater mass, which makes the kinetic energy of a Oscillation stroke is increased, which is a cut particularly tough or porous materials.

Es versteht sich, daß die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale der Erfindung nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the above and those below Features of the invention not yet to be explained in the specified combination, but also in others Combinations or alone can be used without the To leave the scope of the present invention.

In Fig. 1 ist ein erfindungsgemäßes Schneidwerkzeug insgesamt mit der Ziffer 10 bezeichnet.1 shows a cutting tool according to the invention as a whole designated with the number 10.

Es umfaßt einen Oszillationsantrieb 12, an dessen Antriebswelle 14 ein insgesamt mit der Ziffer 16 bezeichnetes U-förmig gewinkeltes Schneidmesser aufgenommen ist, das mit einer gemäß Fig. 2 zwölfkantförmig ausgebildeten Aufnahmeöffnung 18 formschlüssig auf einem entsprechend geformten Mehrkant 20 der Antriebswelle 14 aufgenommen ist und z.B. durch eine Mutter 24 fixiert ist, die auf einen Gewindestutzen 22 der Antriebswelle 14 aufgeschraubt ist.It comprises an oscillation drive 12 on its drive shaft 14 a U-shaped angled, designated overall by the number 16 Cutting knife is included, with a according Fig. 2 twelve-sided receiving opening 18 form-fitting on a correspondingly shaped polygon 20 of the drive shaft 14 and e.g. by a mother 24 is fixed on a threaded connector 22 of the drive shaft 14 is screwed on.

Das Schneidmesser 16 ist - wie bereits erwähnt - im Querschnitt U-förmig abgewinkelt und mit seinem ersten Schenkel, der als Befestigungsteil 32 ausgebildet ist, mit der Antriebswelle 14 verbunden. Das Befestigungsteil 32 ist über einen Zwischensteg 36 mit dem zweiten Schenkel der U-Form verbunden, der als Schneidteil 34 ausgebildet ist.The cutting knife 16 is - as already mentioned - in cross section Angled in a U-shape and with its first leg, which as Fastening part 32 is formed with the drive shaft 14 connected. The fastening part 32 is via an intermediate web 36 connected to the second leg of the U-shape, which as Cutting part 34 is formed.

Während das Schneidteil 34 und der Zwischensteg 36 etwa einen Winkel von 90° miteinander einschließen, schließt das Befestigungsteil 32 mit dem Zwischensteg 36 einen etwas größeren Winkel als 90°, vorzugsweise etwa im Bereich zwischen 93 und 100°, ein. While the cutting part 34 and the intermediate web 36 about one Include an angle of 90 °, the fastening part closes 32 with the intermediate web 36 a slightly larger angle than 90 °, preferably in the range between 93 and 100 °, on.

In Fig. 1 ist das Schneidwerkzeug 10 in seiner Arbeitsstellung dargestellt, in der mittels des Schneidteils 34 ein Klebewulst 30 durchtrennt werden kann, mittels dessen eine Fensterscheibe 26 auf ihrer dem Fahrzeuginneren zugewandten Seite durchgehend mit einem Karosserieflansch 28 verklebt ist.In Fig. 1, the cutting tool 10 is in its working position shown, in which an adhesive bead by means of the cutting part 34 30 can be severed, by means of which a window pane 26 continuously on their side facing the vehicle interior is glued to a body flange 28.

Die besondere Ausgestaltung des erfindungsgemäßen Schneidmessers wird im folgenden anhand der Figuren 2 bis 5 näher erläutert.The special design of the cutting knife according to the invention is explained in more detail below with reference to FIGS. 2 to 5.

Gemäß Fig. 2 besitzt das Schneidteil 34 eine erste gerade gerichtete Schneide 44 auf seiner der Aufnahmeöffnung 18 zugewandten Seite. Der Abstand a zwischen dem Mittelpunkt 48 der Aufnahmeöffnung 18 vergrößert sich zum äußeren Ende 40 des Schneidteils 34 hin. Mit anderen Worten ist das Schneidteil 34 derart in bezug auf die Aufnahmeöffnung 18 abgewinkelt, daß sich dieses nach außen hin von der Aufnahmeöffnung 18 entfernt.2, the cutting part 34 has a first straight Cutting edge 44 on its receiving opening 18 Page. The distance a between the center 48 of the Receiving opening 18 increases towards the outer end 40 of the Cutting part 34 out. In other words, the cutting part is 34 so angled with respect to the receiving opening 18 that this moves outward from the receiving opening 18.

Auf seiner der Aufnahmeöffnung 18 abgewandten Seite besitzt das Schneidteil 34 eine weitere Schneide 46, die an ihrem äußeren Ende 40 über einen abgerundeten Abschnitt in die erste Schneide 44 übergeht.On its side facing away from the receiving opening 18 it has Cutting part 34 a further cutting edge 46, which on its outer End 40 over a rounded section into the first cutting edge 44 passes.

In einem mittleren Bereich des Schneidteils 34 zwischen dem Übergang 38 des Schneidteils zum Zwischensteg 36 hin und dem äußeren Ende 40 besitzt das Schneidteil 34 eine Breite b, die größer ist als die Breite c im Bereich des Übergangs 38 zum Zwischensteg 36. Mit anderen Worten verbreitert sich das Schneidteil vom Zwischensteg 26 aus nach außen hin, bevor es zu seinem äußeren Ende 40 hin wieder zusammenläuft. In a central region of the cutting part 34 between the Transition 38 of the cutting part to the intermediate web 36 and the outer end 40, the cutting part 34 has a width b that is greater than the width c in the area of the transition 38 to Intermediate bridge 36. In other words, this widens Cutting part from the intermediate web 26 outwards before it closes its outer end 40 converges again.

Eine Abwandlung des Schneidmessers gemäß Fig. 2 ist in Fig. 3 dargestellt und insgesamt mit der Ziffer 16a bezeichnet. Dabei werden für entsprechende Teile entsprechende Bezugsziffern verwendet.A modification of the cutting knife according to FIG. 2 is shown in FIG. 3 shown and designated overall by the number 16a. there corresponding reference numbers are used for corresponding parts.

Auf seiner der Befestigungsöffnung zugewandten Seite besitzt das Schneidteil 34a eine in bezug auf die Befestigungsöffnung 18 konvex gekrümmte Schneide 44a. Auf seiner der Befestigungsöffnung 18 abgewandten Seite besitzt das Schneidteil 34a eine in bezug auf die Befestigungsöffnung 18 konkav gekrümmte Schneide 46a. Beide Schneiden 44a, 46a laufen am äußeren Ende 40a zu einer Spitze 42 zusammen.Has on its side facing the mounting opening the cutting part 34a one with respect to the mounting hole 18 convexly curved cutting edge 44a.
