Description
Die Erfindung bezieht sich auf die Verwendung von zwei unterschiedlich großen, gewölbten und mit ihren konkaven Seiten einander zugekehrten Spannflanschen, von denen einer auf einem mittigen Spanndorn des anderen aufgeschoben und mittels einer Mutter festgespannt ist, zum Einspannen faserstoffarmierter, flexibler Trennschleifscheiben.The invention relates to the use of two different sizes, arched and with their concave sides facing clamping flanges, one of which is on a central mandrel of the is pushed onto the other and tightened by means of a nut, for clamping fiber-reinforced, flexible cut-off wheels.
Man kennt einerseits besonders für Heimwerker-Handwerkzeugmaschinen zum Einspannen faserstoffarmierter, flexibler Trennscheiben Spannflansche in Form von flachen Anlageflanschen, welche jedoch keine einwandfreie und stabilisierende Spannverbindung ergeben.On the one hand, it is known especially for do-it-yourself hand machine tools For clamping fiber-reinforced, flexible cutting discs, clamping flanges in the form of flat contact flanges, which, however, do not have a perfect and stabilizing clamping connection result.
Ferner kennt man andererseits zur Halterung der Schleiffolie bei Schleifkissen als Handwerkzeug zwei gegeneinander gewölbte und verspannte Spannflansche mit mittigem zugleich als Griff dienendem Spanndorn. Hier wird das über das Schleifkissen gelegte Schleifpapier an den Flanschrändern umgelegt und sodann zwischen denselben verspannt.Furthermore, on the other hand, two are known for holding the abrasive film in the case of sanding pads as a hand tool Clamping flanges arched and braced against each other with a central clamping mandrel that also serves as a handle. Here the sandpaper placed over the sanding pad is folded over at the flange edges and then tense between them.
Es hat sich nun überraschend gezeigt, daß sich die gegeneinander gewölbten und verspannten Spannflansche mit unterschiedlichem Durchmesser zum sicheren und stabilisierenden Festspannen einer eingelegten Trennscheibe in l'aserstoffarmierter, flexibler Ausführung besonders eignen. Die Trennscheibe wird beim Festspannen schv/ach verformt (gewölbt) und durch ihre Raumform stabilisiert, so daß kein Flattern beim Arbeiten auftritt.It has now been shown, surprisingly, that the clamping flanges, which are arched and braced against one another, are with different diameters for secure and stabilizing clamping of an inserted Cutting disc in a fiber reinforced, flexible design particularly suitable. The cutting wheel is deformed (arched) and through when it is clamped their three-dimensional shape is stabilized so that there is no fluttering when working.
Die Erfindung kennzeichnet sich damit durch dieThe invention is thus characterized by the
ίο Verwendung zweier unterschiedlich großer gewölbter und mit ihren konkaven Seiten einander zugekehrten Spannflanschen, von denen einer auf einem mittigen Spanndorn des anderen aufgeschoben und mittels einer Mutter festspannbar ist, zum Einspannen faserstoffarmierter, flexibler Trennschleifscheiben.ίο Use of two differently sized arched ones and clamping flanges with their concave sides facing each other, one of which is on a central one The clamping mandrel of the other is pushed on and can be tightened by means of a nut, for clamping fiber-reinforced, flexible cut-off wheels.
Die Zeichnung stellt beispielsweise schematisch ein bevorzugtes Ausführuügsbeispiel der Erfindung dar. Und zwar zeigtThe drawing shows, for example, a schematic example of a preferred embodiment of the invention. And that shows
F i g. 1 den Längsschnitt eines erfindungsgemäßen Spannflansches in Explosionsdarstellung und
F i g. 2 den Zusammenbau hierzu.
Hierbei ist in der Zeichnung der gewölbte Spannflansch 2 mit einstückigem Spanndorn 4, auf dessen
Gewinde 5 die Gewindemutter 10 paßt, dargestellt mit dem kalottenförmigen Gegenflansch 8. Die faserstoffarmierte,
flexible Trennscheibe 7 wird hierbei zwischen die Flansche 1 und 8 eingeklemmt. Wie aus F i g. 2
ersichtlich wird, liegt der Rand 3 des Spannflansches 2 der Trennscheibe 7 in anderem Abstand vom Zentrum
an als der Rand 9 des Gegenflansches 8. Hieraus ergibt sich die überraschend feste Halterung und Stabilisierung
der flexiblen Trennscheibe 7. Der Ansatz 6 des Spanndorns 4 wird sodann im Maschinenfutter festgeklemmt.
F i g. 1 shows the longitudinal section of a clamping flange according to the invention in an exploded view and
F i g. 2 the assembly for this.
The drawing shows the arched clamping flange 2 with a one-piece mandrel 4, on whose thread 5 the threaded nut 10 fits, shown with the dome-shaped counter flange 8. The fiber-reinforced, flexible cutting disk 7 is clamped between the flanges 1 and 8. As shown in FIG. 2, the edge 3 of the clamping flange 2 of the cutting disk 7 is at a different distance from the center than the edge 9 of the counter flange 8. This results in the surprisingly firm support and stabilization of the flexible cutting disk 7. The shoulder 6 of the clamping mandrel 4 is then stuck in the machine chuck.
