Abstract

The grinding plate has a flat front face onto which abrasive paper can be adhered. The plate has a cylindrical outer face and a cylindrical drive pin. One end of the pin is connected to the plate and the other can be fitted into a hand held power drill. The front face is roughened and the plate periphery can have equally spaced sharp edges grooves (11).

Description

Die Erfindung betrifft einen Schleifteller aus Kunststoff zum Schleifen und Entgraten von Schneidwerkzeugen mit einer ebenen Stirnfläche, auf der ein Schleifpapier aufgeklebt ist, und mit einer zylindrischen Außenmantelfläche sowie mit einem Antriebsstift, der mit einem Ende in das Bohrfutter einer Handbohrmaschine eingreift.The invention relates to a grinding plate made of plastic for grinding and deburring of cutting tools with a flat face on which an abrasive paper is glued, and with a cylindrical outer surface and with a Drive pin with one end in the chuck of a hand drill intervenes.

Ein derartiger Schleifteller ist aus der DE 35 16 474 C2 bekannt. Dabei ist es von Nachteil, daß das Wechseln des Schleifpapiers mit Schwierigkeiten verbunden ist, da dieses nur schwer vom Schleifteller abzulösen ist und festklebende Schleifpapierreste mühsam manuell entfernt werden müssen, wobei die Stirnfläche des Schleiftellers beschädigt werden kann.Such a grinding plate is known from DE 35 16 474 C2. It is from Disadvantage that changing the sanding paper is difficult, since this is difficult to remove from the sanding plate and is sticky Sandpaper residues must be laboriously removed manually, leaving the face of the sanding plate can be damaged.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schleifteller anzugeben, an dem das aufgeklebte Schleifpapier leicht gewechselt werden kann und bei dem der Zeitbedarf für das Schärfen und das Entgraten deutlich verringert ist.The invention is therefore based on the object of specifying a grinding disc where the glued sandpaper can be easily changed and where the Time required for sharpening and deburring is significantly reduced.

Gelöst wird diese Aufgabe bei dem eingangs genannten Schleifteller dadurch, daß die Stirnfläche rauh ist und daß in der zylindrischen Außenmantelfläche scharfkantige Nuten über der gesamten Breite der Mantelfläche vorhanden sind.This problem is solved in the abrasive disc mentioned above in that the end face is rough and that in the cylindrical outer surface there are sharp-edged grooves over the entire width of the lateral surface.

Durch die rauhe Stirnfläche klebt das Schleifpapier nicht an der gesamten Stirnfläche fest, sondern nur partiell, so daß sich das Schleifblatt leicht wieder ablösen läßt. Dadurch, daß ein zuvor mittels des Schleifblatts geschliffenes Schneidwerkzeug mit der mit Nuten versehenen Mantelfläche des Kunststoffschleiftellers in Kontakt gebracht wird, läßt sich der beim Schleifen entstandene Grat leicht entfernen.Due to the rough face, the sandpaper does not stick to the whole Face firmly, but only partially, so that the sanding sheet is easy again can be replaced. The fact that a previously ground by means of the sanding sheet Cutting tool with the grooved surface of the Plastic grinding plates is brought into contact, the grinding can Remove any burrs that may have formed.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend erläutert.An embodiment of the invention is shown in the drawing and will explained below.

Dabei zeigt Fig. 1 eine Schnittdarstellung des Schleiftellers und Fig. 2 eine Draufsicht auf die Stirnseite des Schleiftellers.Here, FIG 1. 2 shows a sectional view of the grinding plate and Fig. Is a plan view of the front side of the grinding plate.

Der Schleifteller 1 besteht aus Kunststoff und weist eine zylindrische Außen­ mantelfläche 3 auf. Zentral mittig ist ein Antriebsstift 6 vorgesehen, der mit einer Schulter 7 und mit einem unrunden Endstück 8 versehen ist, welches in das Bohrfutter 9 einer Bohrmaschine eingespannt werden kann und von dieser in Drehung versetzt wird. Die dem Antriebsstift 6 gegenüberliegende Seite ist als im wesentlich ebene Stirnfläche 2 ausgebildet, wobei die Stirnfläche 2 eine rauhe Oberfläche aufweist, die in Fig. 2 mit 10 bezeichnet ist. Mittels eines Klebemittels 5 ist darauf ein Schleifpapier 4 aufgeklebt. Aufgrund der Rauhigkeit der Stirnfläche 2 ist das Schleifpapier 4 nicht vollflächig mit der Stirnfläche 2 des Schleiftellers 1 verklebt, sondern haftet nur an denjenigen Stellen fest, die sich wegen der Rauhigkeit über der Oberfläche 10 der Stirnfläche hinaus erheben.The grinding plate 1 is made of plastic and has a cylindrical outer surface 3 . A drive pin 6 is provided in the center, which is provided with a shoulder 7 and with a non-circular end piece 8 , which can be clamped into the drill chuck 9 of a drill and is rotated by the latter. The side opposite the drive pin 6 is designed as an essentially flat end face 2 , the end face 2 having a rough surface, which is designated by 10 in FIG. 2. An abrasive paper 4 is glued thereon by means of an adhesive 5 . Due to the roughness of the end face 2 , the sanding paper 4 is not glued over the entire surface to the end face 2 of the sanding plate 1 , but only adheres firmly to those points which rise above the surface 10 of the end face because of the roughness.

Radial außen ist der Schleifteller 1 mit einer zylindrischen Außenmantelfläche 3 versehen. Darin sind axial verlaufende scharfkantige Nuten 11, 11a eingearbeitet.Radially on the outside, the grinding plate 1 is provided with a cylindrical outer surface 3 . Axially extending sharp-edged grooves 11 , 11 a are incorporated therein.

Ein zu schärfendes Schneidwerkzeug wird zunächst an seiner zu schleifenden Stelle mit dem an der Stirnfläche 2 aufgeklebten Schleifpapier 4 in Kontakt gebracht. Dabei ist der Schleifteller 1 in Drehung, so daß der Schärfvorgang stattfinden kann. Es bleibt jedoch am Schneidwerkzeug ein Grat zurück, der noch beseitigt werden muß. Dazu wird das Schneidwerkzeug an die rotierende Außenmantelfläche 3 gehalten. Durch die dort vorhandenen Nuten 11, 11a wird der Grat in kürzester Zeit entfernt. Der gesamte Schärfvorgang dauert nur etwa vier bis fünf Sekunden. Es ergibt sich somit ein erheblicher Zeitvorteil gegenüber dem herkömmlichen Schärfen, bei dem zunächst das eigentliche Schärfen durchgeführt werden muß, dem sich dann noch ein separater Arbeitsgang zum Entgraten anschließen muß.A cutting tool to be sharpened is first brought into contact at its point to be ground with the abrasive paper 4 adhered to the end face 2 . The grinding plate 1 is rotating so that the sharpening process can take place. However, a burr remains on the cutting tool, which still has to be removed. For this purpose, the cutting tool is held on the rotating outer surface 3 . By the present there grooves 11, 11a of the ridge in the shortest time is removed. The entire sharpening process only takes about four to five seconds. This results in a considerable time advantage over conventional sharpening, in which the actual sharpening must first be carried out, which must then be followed by a separate work step for deburring.

Der erfindungsgemäße Schleifteller 1 ist überall dort anwendbar, wo eine geeignete Antriebsmaschine, wie etwa eine Bohrmaschine, zur Verfügung steht. Als Beispiel sei der Einsatz auf Baustellen genannt. Der Schleifteller 1 ist einfach in der Handhabung und kann auch von Laien ohne Schwierigkeiten verwendet werden.The grinding plate 1 according to the invention can be used wherever a suitable drive machine, such as a drilling machine, is available. One example is the use on construction sites. The grinding plate 1 is easy to use and can also be used by laypersons without difficulty.
