Description
Bandsägemaschinen für Werkstoffe hoher und geringer Festigkeit erfordern verschiedene Schnittgeschwindigkeiten. Bekannt sind diese Maschinen für Metalle und Holz. Da die Schnittgeschwindigkeiten für diese zwei Arten sehr weit auseinanderliegen: und die Bauarten der Metallsägen nicht für die hochdrehzahligen Holzsägen geeignet sind, so ist es notwendig, daß kleinere Maschinenwerkstatten beide Maschinen anschaffen müssen, obgleich in der Regel die Holzsäge für die Modellschreinerei und Verpackungsherstellung nicht ausgenutzt werden kann. Es sind zwar Bandsägemaschinen mit Wechselgetriebe bereits bekannt, jedoch läßt sich bei diesen die Schnittgeschwindigkeit nur in geringen Grenzen ändern.Band saw machines for high and low strength materials require different ones Cutting speeds. These machines are known for metals and wood. There the cutting speeds for these two species are very far apart: and the Types of hacksaws are not suitable for high-speed wood saws, so is it is necessary that smaller machine shops have to purchase both machines, although usually the wood saw for model carpentry and packaging production cannot be exploited. There are band saw machines with change gears already known, but the cutting speed can only be low with these Change boundaries.
Die Erfindung bezweckt nun, eine Bandsägemaschine zu schaffen, die sich durch Einbau einfacher Mittel für beide Werkstoffarten verwenden läßt. Zu diesem Zweck ist erfindungsgemäß außer der bekannten Riemscheibe zum Antrieb der unteren Bandrolle noch ein mit dieser zusammenwirkendes, ausrückbares Untersetzungsgetriebe angeordnet, so daß der Antrieb der unteren Bandrolle entweder unmittelbar über die Riemscheibe für hohe Schnittgeschwindigkeiten oder über das eingerückte Untersetzungsgetriebe für geringe Schnittgeschwindigkeiten erfolgen kann. Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung dargestellt, und zwar zeigt Abb. ι die Bandsägemaschine von vorn gesehen, The invention now aims to create a band saw machine that can be built in can be used more easily means for both types of material. To that end is according to the invention except for the known pulley for driving the lower belt roll another disengageable reduction gear that interacts with this is arranged, so that the drive of the lower reel is either directly via the pulley for high cutting speeds or via the engaged reduction gear for low Cutting speeds can be done. An embodiment of the invention is shown on the drawing, namely Fig. ι shows the band saw machine seen from the front,
Abb. 2 die Getriebeanordnung im Grundriß mittels Riemenantriebes und Abb. 3 die Getriebeanordnung im Grundriß mittels elektromotorischen Antriebes.Fig. 2 the gear arrangement in plan by means of belt drive and Fig. 3 the gear arrangement in plan by means of an electric motor drive.
Der Antrieb erfolgt entweder mittels Riemens auf Leer- und Vollscheibe α (Abb. 1 und 2) oder durch Elektromotor b (Abb. 3). Im letzteren Falle bildet die Motorwelle zugleich die Vorgelegewelle c, auf welcher die Antriebsscheibe d für . die . hohe Schnittgeschwindigkeit und die Stufenscheiben e für das Untersetzungsgetriebe/ für die niederen Schnittgeschwindigkeiten sitzen.It is driven either by means of a belt on an empty and full pulley α (Fig. 1 and 2) or by an electric motor b (Fig. 3). In the latter case, the motor shaft also forms the countershaft c on which the drive pulley d for. the . high cutting speed and the stepped pulleys e for the reduction gear / for the low cutting speeds.
Bei Benutzung der Maschine als schnelllaufende Holzsäge wird das Untersetzungsgetriebe/, welches aus Zahn- oder Reibrädern bestehen kann, ausgerückt und der Riemen auf die Scheiben d, g aufgelegt, während bei Benutzung als Metallsäge der Riemen von den Scheiben d, g abgenommen, dafür der Riemen auf die Scheiben e, h aufgelegt und das Untersetzungsgetriebe f eingerückt wird.When using the machine as a high-speed wood saw, the reduction gear /, which can consist of toothed or friction wheels, is disengaged and the belt is placed on the pulleys d, g , while when using the machine as a hacksaw, the belt is removed from the pulleys d, g Belt is placed on the pulleys e, h and the reduction gear f is engaged.
