Abstract
Description
Die Erfindung betrifft eine Schleifmaschine für Fein- und Lackschliff.The The invention relates to a grinding machine for fine and lacquer grinding.
Eine herkömmliche Handschleifmaschine, insbesondere ein Schwingschleifer weist eine Schwingplatte auf, auf der ein Schleifpapier aufgespannt ist. Durch schnelles Hin- und Herbewegen der Platte (Schwingen) wird das Holz oder das Blech geschliffen.A conventional Hand grinder, in particular an orbital sander has a vibrating plate on which an abrasive paper is stretched. By fast Shaking the plate (swinging) becomes the wood or the Sheet ground.
Die Oberflächenbehandlung, durch die das Holz eine sehr glatte, saubere Oberfläche bekommt, geschieht durch Schleifen mit Schleifpapier. Dabei werden die Holzfasern durch die scharfen Schleifkörner (Körnung) des Schleifpapiers abgeschnitten. Zum Schleifen von Hand dienen Schleifklötze aus Kork (Schleifkork) oder Handschleifmaschinen (Schwingschleifer, Exzenterschleifer, Deltaschleifer). Maschinelles Schleifen geschieht auf Maschinen mit endlosen Bändern (Bandschleifmaschine, Breitbandschleifmaschine, Kantenschleifmaschine). Sowohl beim Maschinen- als auch beim Handschleifen ist wichtig, dass mit scharfen Schleifpapieren und mäßigem Druck gearbeitet wird, damit die Oberfläche nicht beschädigt wird.The Surface treatment, through which the wood gets a very smooth, clean surface happens by sanding with sandpaper. The wood fibers get through the sharp abrasive grains (Grade) of the abrasive paper cut off. Serve for grinding by hand sanding blocks made of cork (grinding cork) or hand grinders (orbital sander, Orbital sander, delta sander). Machine grinding happens on machines with endless belts (Belt sander, wide belt sander, edge sander). Both machine and hand grinding is important that you work with sharp sandpaper and moderate pressure, so that the surface is not damaged becomes.
Die Schleifmaschinen erledigen auch das Schärfen von Werkzeugschneiden (z.B. Hobeleisen oder Stechbeitel) am Schleifbock.The Grinders also do the sharpening of tool cutting edges (e.g., planer iron or chisel) on the trestle.
Ein weit verbreiteter Schleifer ist der Dreieckschleifer. Das ist eine elektrische Handmaschine zum Schleifen von Ecken, kleinen Rundungen und Kanten. Man erkennt ihn an der dreieckigen (deltaförmigen) Schleifplatte. Beim Schleifen bewegt sich die Schleifplatte hin und her (oszilliert).One Widely used grinder is the triangle grinder. This is a electric hand machine for grinding corners, small curves and edges. It can be recognized by the triangular (delta-shaped) Sanding plate. During grinding, the sanding pad moves and forth (oscillates).
Eine Excenter-Schleifmaschine weist einem kreisrundem Schleifteller und rundem Schleifpapier. Sie wird für kleinere Schleifarbeiten verwendet.A Excenter grinding machine has a circular sanding pad and round sandpaper. She is going for used minor grinding.
Diese Maschinen liefern gute Ergebnisse, die auch von der Qualität des Schleifpapiers abhängig sind.These Machines deliver good results, which also depend on the quality of the abrasive paper dependent are.

Die
Die zugrunde liegende Aufgabe ist, eine Schleifmaschine zu schaffen, die in der Lage ist, durch eine verbesserte Schwingenergieübertragung auf die zu schleifende Flächen, sehr schnell und zuverlässig einen mikroskopisch feinen Schliff zu erzeugen.The underlying task is to create a grinding machine which is able to due to an improved swing energy transfer the surfaces to be ground, very fast and reliable to create a microscopically fine cut.
Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.The The object is solved by the features of claim 1.
Vorteile der Erfindung sind:
- – schneller Schleifvorgang,
- – weniger Lärm,
- – sehr feiner Schliff.
- - fast grinding process,
- - less noise,
- - very fine cut.

Es zeigen:It demonstrate:
Eine Variante dieser Maschine kann auch für den Diamanten-Schliff verwendet werden. Der Schliff ist mikroskopisch fein und eignet dafür sehr gut.A Variant of this machine can also be used for the diamond cut become. The cut is microscopic and is very good for it.

Die Piezo-Elemente können auch mechanisch gedreht werden, um dessen Schwingrichtung zu ändern. Die Piezo-Elemente können in einer Walze eingebaut werden, dessen Achse sich drehen lässt.The Piezo elements can also be rotated mechanically to change its direction of vibration. The Piezo elements can be installed in a roller whose axis can be turned.
Auch eine Oberflächen-Umschaltung kann die Schwingrichtung ändern. Das bedeutet, dass wenn die Anschlussstellen an dem Piezo-Element geändert werden, dann schwingt er dementsprechend anders.Also a surface switching can change the swing direction. This means that when the junctions on the piezo element are changed, then he oscillates accordingly.
Um eine höhere Amplitude zu erreichen, kann man mehre Piezo-Elemente aufeinander anordnen, die in der gleichen Schwingphase sich befinden. Dadurch wird die Amplitude verstärkt.Around a higher one To achieve amplitude, you can put several piezo elements on each other arrange, which are in the same phase of oscillation. Thereby the amplitude is amplified.
Die Schwingfrequenz kann auch unter dem Ultraschall-Bereich liegen. Nachteile entstehen wenn der Schallbereich im Hörbereich liegt und unangenehme Töne abgibt.The Oscillation frequency can also be below the ultrasonic range. Disadvantages arise when the sound field is in the listening area and unpleasant Sounds.
Ebenfalls kann ein Bandschleifer mit dem Ultraschallgeber ausgestattet werden. Das Schleifband wird durch eingebaute Piezo-Elemente in Schwingungen gebracht, während das Band läuft. Das macht den Schliff sehr fein. Die Schwingrichtung der Piezo-Elemente kann so gewählt werden, dass sie das Schleifband seitlich zum Schwingen bringen.Also a belt sander can be equipped with the ultrasonic transmitter. The grinding belt is vibrated by built-in piezo elements brought while the tape is running. That makes the cut very fine. The oscillation direction of the piezo elements can be chosen like that Be sure to cause the sanding belt to swing sideways.
