Description
Von den bekannten Bandsägen, deren zurücklaufender Sägeblatteil genau über dem schneidenden Sägeblatteil läuft, unterscheidet sich der Erfindungsgegenstand dadurch, daß durch entsprechendes Schrägstellen der Radscheiben und die Anordnung von Führungen ein Hintereinanderlaufen des Sägeblatttrumms erreicht wird, ohne das- Sägeband erheblich, zu verdrehen. Durch diese Anordnung wird dieFrom the well-known band saws, the saw blade part of which is running back exactly above the cutting saw blade part runs, the subject invention differs in that by appropriately inclining the wheel disks and arranging guides the saw blade strand running one behind the other is achieved without significantly increasing the saw band twist. With this arrangement, the
ίο Lebensdauer des Sägebandes erheblich verlängert. Die Fig. ι stellt eine Vorderansicht der Bandsäge dar. Die Fig. 2 stellt eine Seitenansicht dar. Die Fig. 3 stellt eine schematische Draufsicht dar. Die Fig. 4 zeigt einen Schnitt z-z der Fig. 3. Bei der vorliegenden Bauart werden die Radscheiben α in einem Winkel α zur eigentlichen Zahnspitzenebene χ geneigt angeordnet. Die Radscheiben α sind außerdem dem ziehenden Teil der Bandsäge entsprechend anzuordnen. Die beiden Radscheiben α werden in bekannter Weise z. B. durch den Bügel b verbunden. Die Spannung des Sägeblattes c geschieht durch die eigene Federung des Bügels b oder durch Spannvorrichtungen. Durch die geneigte Anordnung der Radscheiben α läuft das schneidende und das zurücklaufende Sägeblatt c in verschiedenen Ebenen. Zum Zusammenführen des Sägeblattes c dienen bekannte Führungen mit zwei seitlichen Führungsrollen e und einer als Anschlag dienenden Rückenrolle /. Die Rollenführungen müssen nun senkrecht zur eigentlichen Zahnspitzenebene χ eingebaut werden, also die seitlichen Führungsrollen e müssen senkrecht zur Ebenen stehen. Durch die geneigte Anordnung der Radscheiben α und der Anordnung der Führungsrollen e entsteht nur eine ganz minimale Verdrehung des Sägeblattes c. Das zurücklaufende Sägeblatt läuft genau hinter dem schneidenden Sägeblatt c. Zwischen dem schneidenden und zurücklaufenden Sägeblatt c befindet sich ein Abstand, der sich genau nach der Neigung der Radscheiben α richtet. Zur besseren Einführung des Sägeblattes c empfiehlt es sich, die Rollenführungen lösbar anzubringen. ίο The service life of the saw band is significantly extended. FIG. 1 shows a front view of the band saw. FIG. 2 shows a side view. FIG. 3 shows a schematic plan view. FIG. 4 shows a section zz of FIG α arranged inclined at an angle α to the actual tooth tip plane χ. The wheel disks α must also be arranged according to the pulling part of the band saw. The two wheel disks α are in a known manner, for. B. connected by the bracket b . The tension of the saw blade c is done by the own suspension of the bracket b or by clamping devices. Due to the inclined arrangement of the wheel disks α , the cutting and the returning saw blade c run in different planes. Known guides with two lateral guide rollers e and a back roller / serving as a stop are used to bring the saw blade c together. The roller guides must now be installed perpendicular to the actual tooth tip plane χ , i.e. the lateral guide rollers e must be perpendicular to the plane. The inclined arrangement of the wheel disks α and the arrangement of the guide rollers e result in only a very minimal twisting of the saw blade c. The returning saw blade runs exactly behind the cutting saw blade c. There is a distance between the cutting and returning saw blade c , which is based exactly on the inclination of the wheel disks α . For a better introduction of the saw blade c , it is advisable to attach the roller guides in a detachable manner.
Der Antrieb der neuen Maschine kann, wie bekannt, durch Riemenscheibe oder angebauten Motor, der in Verbindung mit einer Radscheibe α steht, oder durch biegsame Welle erfolgen.As is known, the new machine can be driven by a belt pulley or a built-on motor connected to a wheel disk α , or by a flexible shaft.
