Description

Maschine zum beiderseitigen Schleifen der Schneideflächen von Messerklingen mittels einander übergreifender umlaufender Schleifscheiben. Messerschleifmaschinen mit mehreren auf parallelen Achsen gelagerten,. ineinander übergreifenden Schleifscheiben sind bekannt.Machine for grinding the cutting surfaces of knife blades on both sides by means of overlapping rotating grinding wheels. Knife sharpening machines with several mounted on parallel axes. interlocking grinding wheels are known.

Die Erfindung betrifft eine solche Maschine mit der Neuerung, daß die Schleifscheibenspindeln in um die Achse ihrer Antriebsräder (Seil- oder Zahnrädergetriebe) sch-,vingbaren, durch Zwieselschraube einstellbaren Armen gelagert sind, die gleichzeitig die Schutzhauben für die Schleifscheiben tragen.The invention relates to such a machine with the innovation that the grinding wheel spindles in around the axis of their drive wheels (cable or gear drive) rotatable, adjustable arms by means of a twin screw are mounted, which at the same time wear the protective hoods for the grinding wheels.

In der Zeichnung ist eine Ausführungsform eeranschaulicht.One embodiment is illustrated in the drawing.

Abb. z zeigt eine Seitenansicht, Abb. a eine Oberansicht, Abb.3 einen Einzelteil und Abb. q. eine Oberansicht nach Abb. 3. Das Maschinengestell besteht aus einem Bock a mit Fußplatte b und ist mit mehreren Lagernaben c und cl versehen. Diese Naben dienen zur Aufnahme der Wellen e. Der Bock a hat einen Sattel f, auf welchem die U-förmig ausgebildeten Schutzhauben g sitzen. Die Schleifscheibenwellen d lagern in den Seitenwandungen der Hauben g, die die Schleifscheiben h teilweise umfassen. Die Schutzhauben stehen mit einer mit Rechts-und Linksgewinde versehenen Einstellschraube i in Verbindung. Die als Schutzhaube dienenden Lagergehäuse g haben entsprechend lange Schenkel und werden auf dem Bock a so befestigt, daß sie um die Wellen d schwingen können und mit ihnen die in den Hauben gelagerten Schleifscheiben, deren Achsen parallel zueinander liegen. Der Antrieb der Schleifscheiben erfolgt durch Seilscheibe j, von welcher das Seil in um die Umführungsrolle l auf die Triebscheibe k führt. Von hier wird das Seil in über die Umführungsrolle n auf die Triebscheibe o geführt. Von der Triebscheibe o führt das Seil m an der Umführungsrolle p vorbei zurück zum Antriebsrad j. Von den Seilscheiben q oder Zahnrädern wird der Antrieb auf die entsprechend kleineren, aber gleich großen Seilscheiben r oder Zahnräder übertragen. Der Antrieb kann auch nur durch Zahnräderübersetzung erfolgen. Der Umlauf der Schleifscheiben erfolgt entgegen der Messerschneide. Das Messer wird in Richtung seiner Längsachse hin und her bewegt und dabei an beiden Schneideflächen gleichzeitig geschliffen. Bei Abnutzung der Schleifscheiben erfolgt ihre Nachstellung durch Betätigung der Zwieselschraube.Fig. Z shows a side view, Fig. A shows a top view, Fig. 3 shows an individual part and Fig. Q. a top view according to Fig. 3. The machine frame consists of a bracket a with a base plate b and is provided with several bearing hubs c and cl. These hubs are used to accommodate the shafts e. The bracket a has a saddle f on which the U-shaped protective hoods g sit. The grinding wheel shafts d are supported in the side walls of the hoods g, which partially enclose the grinding wheels h. The protective hoods are connected to an adjusting screw i provided with a right-hand and left-hand thread. Serving as a protective cover bearing housing g have correspondingly long legs and are attached to the bracket a so that they can swing around the shafts d and with them the grinding wheels mounted in the hoods, the axes of which are parallel to each other. The grinding wheels are driven by a pulley j, from which the rope leads around the pulley l to the drive pulley k. From here the rope is guided over the pulley n onto the drive pulley o. From the drive pulley o the cable m leads past the pulley p back to the drive wheel j. The drive is transmitted from the pulleys q or gears to the correspondingly smaller but equally large pulleys r or gears. The drive can also only take place through gear transmission. The grinding wheels rotate against the knife edge. The knife is moved back and forth in the direction of its longitudinal axis and is sharpened on both cutting surfaces at the same time. If the grinding wheels wear out, they can be readjusted by actuating the Zwiesel screw.
