Description

Schleifscheibe Die Erfindung betrifft eine Schleifscheibe zum Schleifen von Profilen aus Holz, bei welcher auf einem einen festen Scheibenkern umschließenden elastischen Ringkörper zwei elastische kegelstumpfförmige Schleifkörper angeordnet sind, deren Außenränder im Scheitelpunkt des von ihnen gebildeten Winkels liegen.Grinding wheel The invention relates to a grinding wheel for grinding of profiles made of wood, in which on a fixed disc core enclosing elastic ring body two elastic frustoconical grinding body arranged whose outer edges lie at the apex of the angle they form.

Beim Gebrauch derartiger Schleifscheiben hat sich herausgestellt, daß beim Schleifen von winklig zueinander verlaufenden Flächen konvexe Unebenheiten im Werkstückprofil mit den Schleifscheiben nicht eingeebnet werden können, wodurch die Außenräfider der Schleifkörper vorschnell verschleißen, und zwar insbesondere dann, wenn die Werkstücke im Scheitel des Winkels stellenweise nicht scharfkantig vorgearbeitet sind.When using such grinding wheels it has been found that when grinding surfaces at an angle to one another, convex bumps in the workpiece profile cannot be leveled with the grinding wheels, which means the outer races of the grinding wheels wear out prematurely, in particular when the workpieces are not sharp-edged in places at the apex of the angle are prepared.

Um nun ein Nacharbeiten der mangelhaften Profile zu erreichen und einen vorzeitigen Verschleiß der Außenränder der Schleifkörper zu vermeiden, sind gemäß der Erfindung in dem Scheibenkern radial einstellbare Fräsmesser angebracht, deren Schneiden durch den elastischen Ringkörper hindurchgeführt sind.In order to rework the defective profiles and premature wear of the outer edges of the grinding tools are to be avoided according to the invention in the disc core mounted radially adjustable milling knives, the cutting edges of which are passed through the elastic ring body.

Mit Hilfe derart ausgebildeter Schleifscheiben ist es möglich, Holzteile mit anhaftendem Leim, eingewachsenen Ästen od. dgl., also Stoffe mit unterschiedlicher Konsistenz zu schleifen, ohne einen erhöhten Verschleiß an Schleifkörpem bzw. größere Schleiftoleranzen in Kauf nehmen zu müssen.With the help of grinding wheels designed in this way, it is possible to produce wooden parts with adhering glue, ingrown branches or the like, so substances with different Sanding consistency without increased wear and tear on sanding tools or larger ones Having to accept grinding tolerances.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Ab b. 1 eine nach der Erfindung ausgebildete Schleifscheibe in Seitenansicht und teils im Schnitt, A b b. 2 die Schleifscheibe nach A b b. 1 im Querschnitt.An exemplary embodiment of the invention is shown in the drawing. It shows Ab b. 1 a grinding wheel designed according to the invention in side view and partly in section, A b b. 2 the grinding wheel according to A b b. 1 in cross section.

Der aus Metall bestehende feste Scheibenkern 1 ist von einem elastischen Ringkörper 2 umschlossen, über den zwei vorgeformte schalenförmige Schleifkörper 3 mit kegelstumpfförmigen Schleifflächen gestülpt und mittels zweier Flansche 4 zentriert sowie an den elastischen Ringkörper 2 gepreßt werden. Nach der Montage liegen mithin die Außenränder der beiden Schleifkörper 3 im Scheitelpunkt des von ihnen gebildeten Winkels, wie es in Ab b. 2 veranschaulicht ist. In dem Scheibenkern 1 sind in dem dargestellten Ausführungsbeispiel vier gleichmäßig auf den Umfang verteilte Fräsmesser 5 mittels Schrauben 6 in radialer Richtung verstellbar befestigt. Die Schneiden dieser Messer 5 sind durch Ausnehmungen des elastischen Ringkörpers 2 und der Schleifkörper 3 hindurchgeführt und werden so auf das Profil der Schleifkörper 3 eingestellt, daß sie erst bei Auftreten von körperlichen Abweichungen (Erhöhungen) des an sich vorgearbeiteten Profils ansprechen.The solid disc core 1 made of metal is enclosed by an elastic ring body 2, over which two preformed cup-shaped grinding bodies 3 with frustoconical grinding surfaces are placed and centered by means of two flanges 4 and pressed against the elastic ring body 2. After assembly, the outer edges of the two grinding bodies 3 are therefore at the apex of the angle they form, as shown in Ab b. 2 is illustrated. In the illustrated embodiment, four milling knives 5 evenly distributed over the circumference are fastened in the disk core 1 so as to be adjustable in the radial direction by means of screws 6. The cutting edges of these knives 5 are passed through recesses in the elastic ring body 2 and the grinding body 3 and are adjusted to the profile of the grinding body 3 so that they only respond when physical deviations (elevations) occur in the pre-machined profile.

Die so ausgebildeten Schleifscheiben sind nicht nur zum Schleifen von Holzteilen verwendbar, vielmehr lassen sich damit auch Kunststoffprofile schleifen.The grinding wheels designed in this way are not just for grinding can be used for wooden parts, but can also be used to grind plastic profiles.
