Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Schneiden von Dämmstoff, insbesondere zum Schneiden von Mineral-, Stein- oder Glaswolle, als ein besonders kritisches Beispiel für mit Fasern gebildete Dämmstoffe.The invention relates to a device for cutting insulating material, in particular for cutting mineral, stone or glass wool, as a particularly critical example of insulating materials formed with fibers.
Für Isolationszwecke an Gebäuden werden mit Fasern gebildete Dämmstoffe eingesetzt. Diese werden häufig als plattenförmige Gebilde zur Verfügung gestellt. Vor Ort müssen diese dann auf die jeweils erforderlichen Abmaße zugeschnitten werden. Üblicherweise werden dabei Schneidwerkzeuge eingesetzt, da sich diese zum Trennen der faserigen Dämmstoffe als geeigneter, als andere Trennwerkzeuge herausgestellt haben.For insulation purposes on buildings insulating materials formed with fibers are used. These are often provided as plate-shaped structures. These must then be cut to the required dimensions on site. Usually cutting tools are used because they have been found to be more suitable for separating the fibrous insulation than other cutting tools.
Dabei wird ein Schneidmesser mit Hilfe einer Mechanik vertikal von oben nach unten bewegt und ein plattenförmiger Dämmstoffverbund entlang der Schneidkante eines Schneidmessers durchtrennt.In this case, a cutting blade is moved vertically from top to bottom by means of a mechanism and a plate-shaped insulation composite is cut along the cutting edge of a cutting blade.
Insbesondere beim Zuschnitt von Glaswolle hat es sich aber herausgestellt, dass die Schärfe der Schneidmesser bereits nach kurzem Gebrauch soweit nachlässt, dass ein aufwändiges Nachschleifen oder gar ein Austausch der Schneidmesser erforderlich wird.In particular, when cutting glass wool, it has been found that the sharpness of the cutting blade decreases after a short use so far that a complex regrinding or even replacement of the cutting blade is required.
Außerdem führen nicht ausreichend scharfe Schneidkanten zur Ausbildung einer Schnittkante am Dämmstoff oder von Glaswolle, die den Ansprüchen nicht genügt.In addition, not sufficiently sharp cutting edges lead to the formation of a cut edge on the insulating material or glass wool, which does not meet the requirements.
Die bekannten Schneidvorrichtungen sind außerdem sehr aufwändig konstruiert und können daher nicht einfach von einem Ort zu einem anderen Ort transportiert und dann vor Ort wieder einfach und schnell betriebsbereit gemacht werden.The known cutting devices are also very complicated in design and therefore can not be easily transported from one location to another location and then made easy and fast on the ground again.
Es ist daher Aufgabe der Erfindung, Möglichkeiten anzugeben, mit denen die Standzeiten von Schneidmessern beim Schneiden von Dämmstoff erhöht werden können und eine einfache Handhabbarkeit der eingesetzten Vorrichtung dabei erreichbar ist.It is therefore an object of the invention to provide ways in which the life of cutting blades when cutting insulation material can be increased and easy handling of the device used is achievable.
Erfindungsgemäß wird diese Aufgabe mit einer Vorrichtung, die die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen können mit in untergeordneten Ansprüchen bezeichneten Merkmalen erreicht werden.According to the invention, this object is achieved with a device having the features of claim 1. Advantageous embodiments and further developments can be achieved with features described in the subordinate claims.
Die erfindungsgemäße Vorrichtung kann vorteilhaft mit einer Führung für ein Schneidmesser versehen sein. Außerdem ist zumindest eine Seite der Schneide des Schneidmessers angeschliffen. Durch den Anschliff sind mit dem Stahlwerkstoff der Schneide an der Schneidkante Mikrozähne ausgebildet. Durch das Anschleifen können an der jeweils angeschliffenen Seite Riefen ausgebildet sein, deren Enden die Mikrozähne bilden. Dabei ist es besonders vorteilhaft, dass unregelmäßige Mikrozähne ausgebildet sind. Dabei kann deren jeweilige Größe, Tiefe, Winkel, der Abstand von nebeneinander angeordneten Mikrozähnen und/oder geometrische Gestalt der vorhandenen Mikrozähne entlang der Schneidkante variieren.The device according to the invention may advantageously be provided with a guide for a cutting blade. In addition, at least one side of the cutting edge of the cutting blade is ground. By the bevel are formed with the steel material of the cutting edge on the cutting edge micro teeth. By grinding can be formed on the respective ground side grooves, the ends of which form the micro teeth. It is particularly advantageous that irregular micro-teeth are formed. In this case, their respective size, depth, angle, the distance of juxtaposed micro-teeth and / or geometric shape of the existing micro-teeth vary along the cutting edge.
Für die Ausbildung der Mikrozähne und/oder der Riefen oder ein Nachschleifen kann bevorzugt eine Trennschleifscheibe mit grober Körnung eingesetzt werden. Bei einem Nachschleifen können die Mikrozähne ohne weitere zusätzliche Maßnahen mit gleichen Eigenschaften ausgebildet werden. Der erforderliche Aufwand ist gering.For the formation of the micro-teeth and / or the grooves or regrinding, it is possible with preference to use a coarse grain cut-off wheel. In a regrinding, the micro-teeth can be formed without any additional measures with the same properties. The required effort is low.
Es hat sich als besonders günstig herausgestellt für das Schneidmesser einen un- oder niedriglegierten Edelstahl, wie z. B. einen Stahl C 75 S oder ein Federbandblech 1600 + 50 – 50 M, bevorzugt C 100 S (Werkstoffnummer 1.1274 nach EN 10132-4) einzusetzen. Der Stahl sollte gehärtet und anschließend angelassen, geglüht und kalt gewalzt werden.It has proven to be particularly favorable for the cutting blade a non-alloyed or low-alloy stainless steel, such. B. a steel C 75 S or a spring band sheet 1600 + 50 - 50 M, preferably C 100 S (material number 1.1274 according to EN 10132-4) use. The steel should be hardened and then tempered, annealed and cold rolled.
Die Riefen sollten zumindest annähernd senkrecht zur Längsachse des Schneidmessers ausgerichtet sein. Sie sind dadurch parallel zur Schneidbewegung ausgerichtet.The grooves should be aligned at least approximately perpendicular to the longitudinal axis of the cutting blade. They are thereby aligned parallel to the cutting movement.
An der Vorrichtung kann auch eine Halterung für Dämmstoff vorhanden sein. Dabei können dann eine Führung für das Schneidmesser und eine Halterung für Dämmstoff senkrecht zueinander ausgerichtet sein.On the device may also be a holder for insulation material. In this case, then a guide for the cutting blade and a holder for insulation material can be aligned perpendicular to each other.
Mit einer Halterung kann ein Verrutschen des Dämmstoffs beim Schneiden vermieden und ein maßgenaues Schneiden erreicht werden.With a holder slippage of the insulating material can be avoided when cutting and a dimensionally accurate cutting can be achieved.
An der Halterung für Dämmstoff oder der Führung kann mindestens eine Längenmesseinrichtung angeordnet sein, mit der ein maßgenaues Schneiden erleichtert werden kann.At the holder for insulation material or the guide can be arranged at least one length measuring device with which a dimensionally accurate cutting can be facilitated.
Vorteilhaft ist es, an der Führung für das Schneidmesser und/oder der Halterung für Dämmstoff Stützelemente anzubringen. Besonders vorteilhaft sind die Stützelemente gelenkig befestigt.It is advantageous to attach to the guide for the cutting blade and / or the holder for insulation supporting elements. Particularly advantageously, the support elements are hinged.
Stützelemente können auch einen Anschlag für Dämmstoff bilden.Support elements can also form a stop for insulation.
Dadurch kann die Vorrichtung Platz sparend für einen Transport oder bei einer Lagerung sein. Bei Bedarf kann sie so einfach und in kurzer Zeit einsatzbereit gemacht werden, indem die Stützelemente einfach in ihre Funktionsstellung geklappt werden.This allows the device to save space for transport or storage. If necessary, it can be made so easy and quickly ready for use by the support elements are easily folded into their functional position.
Nachfolgend soll die Erfindung beispielhaft näher beschrieben werden.The invention will be described in more detail by way of example below.
