Description

Vorrichtung zum Schleifen von gebogenen Sensen- o. dgl. Schneiden. Das Schleifen von Sensen geschah bisher von Hand, indem die Sense an den sich drehenden Schleifstein gedrückt wurde. Dieses Verfahren ist unzweckmäßig, weil ein gleichmäßiger Schliff hierbei nicht zu erreichen ist.Device for grinding curved scythes or similar cutting edges. The sharpening of scythes used to be done by hand by attaching the scythe to the rotating one Whetstone was pressed. This method is inexpedient because it is more uniform Grinding cannot be achieved here.

Zweck der Erfindung ist, das Werkstück mit stets gleichmäßigem Druck und in beliebigem Abstand an die Schleifscheibe heranzubringen und an dieser selbsttätig entlangzuführen. Das wird dadurch erreicht, daß die Sense mit der Schneide an zwei verstellbaren Anschlagrollen zu liegen kommt und gleichzeitig durch zwei Paar geriffelter, in ihrem Abstande einstellbarer Walzen, die vom Schleifscheibenantrieb in Bewegung gesetzt werden, gleichmäßig vorgeschoben wird.The purpose of the invention is to always apply even pressure to the workpiece and bring it up to the grinding wheel at any distance and automatically on it to lead along. This is achieved by placing the scythe with the cutting edge on two adjustable stop rollers come to rest and at the same time by two pairs of corrugated, in their spacing of adjustable rollers from the grinding wheel drive be set in motion, is advanced evenly.

In der Zeichnung ist eine derartige Vorrichtung dargestellt.Such a device is shown in the drawing.

Abb. z zeigt die Vorderansicht, Abb. 2 die Seitenansicht, Abb: 3 die verstellbaren Anschlagrollen a und Abb. q. den Antrieb der Führungsrollen b. Eine Schleifscheibe c wird bei Handantrieb durch Vorgelege, bei Kraftantrieb unmittelbar in schnelle Umdrehung versetzt. Auf einer Grundplatte d ist eine die Schleifscheibe umfassende Gabel e schwenkbar und mittels 'Stellschraube s einstellbar befestigt. Beiderseits der Schleifscheibe sind an der Gabel die Anschlagrollen a gelagert, die je nach der gewünschten Breite des Dangels an der Gabel einzustellen sind (Abb.3). Außerdem sind zwei Paar geriffelter Führungsrollen b angeordnet. Letztere sind durch Zahnräder verbunden und haben gemeinsamen Antrieb (4bb. .i) von der Hauptwelle aus. Um ein geringes Anheben der oberen Walzen b zu ermöglichen, sind diese in schwenkbaren Bügeln f und g federnd gelagert. Zum @chleifen wird die Sense so weit zwischen die Führungsrollen b geschoben, bis die Sohneide die Anschlagrollen a berührt. Beim Ingängsetzen des Antriebes bewirkt die Schleifscheibe den erforderlichen Hohlschliff der Sense und zieht diese gleichzeitig gegen die Anschlagrollen. Die Vorrichtung dient nicht nur zum Schleifen neuer, sonldern auch alter, wellenförmiger Sensen- o. dgl. Schneiden.Fig. Z shows the front view, Fig. 2 the side view, Fig: 3 the adjustable stop rollers a and fig. q. the drive of the guide rollers b. One Grinding wheel c is driven by a back gear with manual drive and directly with power drive set in rapid rotation. On a base plate d is the grinding wheel Comprehensive fork can be swiveled and fastened so that it can be adjusted by means of adjusting screws. The stop rollers a are mounted on the fork on both sides of the grinding wheel, which can be adjusted on the fork depending on the desired width of the tang (Fig.3). In addition, two pairs of corrugated guide rollers b are arranged. The latter are through Connected gears and have a common drive (4bb. .I) from the main shaft. In order to allow a slight lifting of the upper rollers b, they are pivotable Brackets f and g are spring-loaded. For @grinding the scythe is so far between the Guide rollers b pushed until the son side touches the stop rollers a. At the When the drive is engaged, the grinding wheel produces the required hollow grinding the scythe and pulls it against the stop rollers at the same time. The device is not only used for grinding new, but also old, wave-shaped scythe or the like. Cutting.

PATENTANSPRUCH: Vorrichtung zum Schleifen von .gebogenen Sensen- o. dgl. Schneiden durch Entlangführen an einer umlaufenden Schleifscheibe in Anlage mit einstellbaren seitlichen Führungsrollen, dadurch gekennzeichnet, daß die Führungsrollen aus zwei Paaren geriffelter, in ihrem Abstande einstellbarer Walzen (b) bestehen, die vom Schleifscheibenantrieb aus in vorschiebende Bewegung versetzt werden, und tlaß die Arbeitslage des Werkstückes gegenüber dem Werkzeug zwischen den Führungsrollen (b) durch verstellbare, an der Schneide anliegende Anschlagrollen (a) bestimmt wird. Claim: device for grinding curved scythes o. The like. Cutting by guiding them along a rotating grinding wheel in contact with adjustable lateral guide rollers, characterized in that the guide rollers consist of two pairs of corrugated, spaced adjustable rollers (b) which be set in forward motion by the grinding wheel drive, and the working position of the workpiece relative to the tool between the guide rollers (b) is determined by adjustable stop rollers (a) resting on the cutting edge.
