Abstract
Description
Die Erfindung betrifft eine Schutzabdeckung mit erhöhter Durchschlagfestigkeit nach dem Oberbegriff des Anspruchs 1.The invention relates to a protective cover with increased dielectric strength according to the preamble of claim 1.
Schutzabdeckungen der oben genannten Art dienen beispielsweise zur Abdeckung von beweglichen Teilen an Werkzeugmaschinen. Dabei wird der Bereich, in dem die beweglichen Teile angeordnet sind, durch die Schutzabdeckung vom Außenbereich, in dem sich beispielsweise ein Bediener der Werkzeugmaschine aufhält, abgeschirmt, so dass zum Einen ein versehentliches Eingreifen des Bedieners in die beweglichen Teile der Werkzeugmaschine verhindert und zum Anderen ein unbeabsichtigtes Austreten von beispielsweise Spänen und Hilfsstoffen wie z. B. Bohremulsion und Schmiermitteln verringert oder ausgeschlossen wird. Wenngleich bei den bekannten Schutzabdeckungen diese Aufgaben in der Regel zuverlässig erfüllt werden, reicht die Schutzwirkung möglicherweise dann nicht aus, wenn sich Teile mit hoher Geschwindigkeit und/oder größerer Masse von der Werkzeugmaschine oder dem bearbeiteten Werkstück lösen.Protective covers of the above type are used, for example, to cover moving parts on machine tools. In this case, the area in which the moving parts are arranged, shielded by the protective cover from the outside, in which, for example, an operator of the machine tool resides, so that on the one hand prevents accidental intervention of the operator in the moving parts of the machine tool and on the other unintentional leakage of, for example chips and excipients such. As drilling emulsion and lubricants is reduced or excluded. Although in the known protective covers these tasks are usually reliably met, the protective effect may not be sufficient if parts detach at high speed and / or greater mass from the machine tool or the machined workpiece.
Ausgehend von diesem Stand der Technik ist es die Aufgabe der vorliegenden Erfindung, eine Schutzabdeckung zu schaffen, die eine erhöhte Durchschlagsfestigkeit aufweist.Based on this prior art, it is the object of the present invention to provide a protective cover which has an increased dielectric strength.
Diese Aufgabe wird durch eine Schutzabdeckung nach der Lehre des Anspruchs 1 gelöst.This object is achieved by a protective cover according to the teaching of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Die Schutzabdeckung der Erfindung weist zunächst einen konventionellen Aufbau mit einer mit einer Mehrzahl Schutzabdeckungselementen auf, die gegeneinander verschiebbaren derart angeordnet uns ausgebildet sind, dass sie einander zumindest abschnittsweise teleskopartig übergreifen. Dabei kann die Schutzabdeckung balglos ausgebildet sein oder aber zusätzlich mit einem Faltenbalg auf der Rückseite versehen sein.The protective cover of the invention initially has a conventional construction with one having a plurality of protective cover elements, which are arranged so as to be displaceable relative to one another and designed to telescopically engage one another at least in sections. In this case, the protective cover may be formed without bellows or be additionally provided with a bellows on the back.
Erfindungsgemäß sind die Schutzabdeckungselemente zumindest in dem Abschnitt, in dem sie zum abzudeckenden Bereich weisen, mehrlagig, insbesondere doppellagig, ausgeführt. Dadurch ergibt sich eine im Vergleich zur einlagigen Ausgestaltung deutliche verbesserte Durchschlagfestigkeit. Im Vergleich zu einem einlagigen Aufbau mit doppelter Materialstärke ergibt sich zudem eine verbesserte Flexibilität der Schutzabdeckungselemente und damit der Schutzabdeckung insgesamt.According to the invention, the protective cover elements, at least in the section in which they point to the area to be covered, multi-layered, in particular double-layered executed. This results in a significantly improved dielectric strength compared to the single-layer design. Compared to a single-layer construction with double the thickness of the material also results in an improved flexibility of the protective cover elements and thus the protective cover as a whole.
Die Gestalt der Schutzabdeckungselemente ist grundsätzlich beliebig und hängt im wesentlichen vom jeweiligen Anwendungsfall, insbesondere der Länger der Schutzabdeckung, deren räumliche Orientierung und den zu erwartenden Angriffskräften von abzuhaltenden Partikeln. Nach einem bevorzugten Ausführungsbeispiel der Erfindung jedoch sind die Schutzabdeckungselemente im wesentlichen L-förmig und insgesamt mehrlagig, insbesondere doppellagig, ausgebildet. „Insgesamt” in diesem Zusammenhang bedeutet insbesondere, dass die Mehrlagigkeit an beiden Schenkeln der L-förmigen Schutzabdeckungselemente gegeben sein soll.The shape of the protective cover elements is basically arbitrary and depends essentially on the particular application, in particular the length of the protective cover, their spatial orientation and the expected attack forces of particles to be held. According to a preferred embodiment of the invention, however, the protective cover elements are substantially L-shaped and overall multi-layered, in particular double-layered, formed. "Overall" in this context means in particular that the multi-layer should be given on both legs of the L-shaped protective cover elements.
Vorzugsweise bestehen die Lagen aus im wesentlichen identischen Schutzabdeckungselementen, die über- bzw. nebeneinander angeordnet sind. Dadurch ergibt sich ein einfacher Aufbau mit geringer Anzahl unterschiedlicher Teile.Preferably, the layers consist of substantially identical protective cover elements, which are arranged above or next to each other. This results in a simple structure with a small number of different parts.
Im einfachsten Fall liegen die Lagen der Schutzabdeckungselemente lediglich über- bzw. nebeneinander und werden lediglich beispielsweise im Bereich der seitlichen Führungen miteinander fixiert. Nach einem weiteren Ausführungsbeispiel der Erfindung jedoch sind die Lagen zumindest abschnittsweise miteinander verbunden, insbesondere miteinander verschraubt, vernietet oder verklebt. Dabei kann die Verbindung punktuell, flächig oder teilflächig erfolgen.In the simplest case, the layers of the protective cover elements are only above or next to each other and are merely fixed together, for example, in the region of the lateral guides. According to a further embodiment of the invention, however, the layers are at least partially connected to each other, in particular screwed together, riveted or glued. In this case, the connection can be made pointwise, flat or partial area.
Nach einem weiteren Ausführungsbeispiel sind die Lagen derart miteinander verklebt, dass sich ein im wesentlichen vollflächiger sandwichartiger Aufbau ergibt.According to a further embodiment, the layers are glued together in such a way that results in a substantially full-surface sandwich-like structure.
Das Material der Schutzabdeckungselemente ist grundsätzlich beliebig und hängt wiederum im wesentlichen vom jeweiligen Anwendungsfall ab. Vorzugsweise jedoch bestehen die die Schutzabdeckungselemente aus Kunststoff, Metall oder einer Kombination dieser Werkstoffe. Die Materialstärke der Schutzabdeckungselemente beträgt vorzugsweise zwischen 0,2 und 0,5 mm, insbesondere zwischen 0,25 und 0,35 mm. Dabei kann die Materialstärke der einzelnen Lagen gleich oder unterschiedlich sein.The material of the protective cover elements is basically arbitrary and in turn depends essentially on the particular application. Preferably, however, the protective cover elements are made of plastic, metal or a combination of these materials. The material thickness of the protective cover elements is preferably between 0.2 and 0.5 mm, in particular between 0.25 and 0.35 mm. The material thickness of the individual layers may be the same or different.
Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel zeigenden Zeichnung näher erläutert. Es zeigtIn the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. It shows
