Description
Widerlager auf der Innenseite des wandernden Schleifbands von Bandschleifmaschinen. Die Erfindung betrifft eine weitere Ausgestaltung des Widerlagers auf der Innenseite des wandernden Schleifbands von Bandschleif- und Poliermaschinen.Abutment on the inside of the moving sanding belt of belt sanding machines. The invention relates to a further embodiment of the abutment on the inside of the traveling sanding belt from belt sanding and polishing machines.
Es hat sich herausgestellt, daß bei den bekannten Maschinen während des Betriebes sehr leicht eine übermäßige Erwärmung des Schleifbandes eintritt, durch die die Schleifvorrichtung selbst und auch die zu schleifenden Teile nachteilig beeinflußt werden.It has been found that in the known machines during excessive heating of the sanding belt occurs very easily during operation, disadvantageous by the grinding device itself and also the parts to be ground to be influenced.
Diese Nachteile können beseitigt werden, wenn für eine ausreichende Kühlung des Schleifbandes Sorge getragen wird. Zu diesem Zweck wird> erfindungsgemäß das am Bande anliegende Widerlager auf der ganzen Anlagefläche mit .durchgehenden, längs oder diagonal verlaufenden Nuten versehen, dwrch ctie die vom Bande mitgenommene Luft hindurchstreichen kann.These disadvantages can be eliminated if sufficient cooling of the grinding belt is ensured. For this purpose> according to the invention provided the signal at the band abutment around the contact surface with .durchgehenden along diagonal or grooves dwrch ctie the entrained air from the band can pass deleted.
In der Zeichnung ist ein gemäß der Erfindung ausgebildetes Widerlager für eine Bandschleifmaschine beispielsweise dargestellt, und zwar zeigen Abb. r die Schleif- und Poliervorrichttu@g in schematischer Darstellung in Seitenansicht und Abb. z eine Draufsicht auf die Unterseite des Widerlagers in vergrößertem Maßstabe. Die Schleif- und Poliervorrichtung besteht im wesentlichen aus zwei Walzen a, b, die in geeigneter Weise, z. B. durch einen Elektromotor, mit der nötigen Umdrehungszahl angetrieben werden. Über die Walzen ist ein endloses Schleifband c geführt. Die Spannung des Schleifbandes känn durch Nähern oder Entfernen der Walzen .a, b voneinander eingestellt werden. Oberhalb der Schleifstrecke befindet sich das Schleifbandwider-Iagerd, das fest oder nachgiebig nv.t den Konsolen der Vorrichtung verbunden ist. Das Schleifband c wird durch das Widerlager d mit bestimmtem Druck auf die durch ein -Transportbande unter die Schleifvorrichtung geführten Schleifteile gedrückt.In the drawing, an abutment designed according to the invention for a belt grinder is shown, for example, namely Fig. R shows the grinding and polishing device in a schematic representation in side view and Fig. Z is a plan view of the underside of the abutment on an enlarged scale. The grinding and polishing device consists essentially of two rollers a, b, which in a suitable manner, for. B. driven by an electric motor at the required number of revolutions. An endless sanding belt c is guided over the rollers. The tension of the sanding belt can be adjusted by moving the rollers a , b closer to or away from each other. Above the sanding section is the sanding belt counter-bearing, which is connected firmly or flexibly to the consoles of the device. The grinding belt c is pressed by the abutment d with a certain pressure onto the grinding parts guided by a conveyor belt under the grinding device.
Da infolge der verhältnismäßig hohen Umdrehungszahl des Schleifbandes durch dessen Reibung an dem Widerlager d leicht ,eine unzulässig hohe Erwärmung eintreten kann, muß für ausreichende Kühlung Sorge getragen werden.As a result of the relatively high number of revolutions of the sanding belt due to its friction on the abutment d easily, an inadmissibly high heating can occur, sufficient cooling must be ensured.
Zu diesem Zweck ist das Widerlager d an der dem Schleifband zugekehrten Seite mit durchgehenden, längs oder diagonal verlaufenden Nuten f versehen (Abb. z). Die durch das Schleifband mitgerissene Luft wird durch die Nuten zwischen Widerlager und Schleifband geführt und sorgt für eine genügende Wärmeabführung.For this purpose, the abutment d is on the one facing the grinding belt Provide the side with continuous, longitudinal or diagonal grooves f (Fig. z). The air entrained by the sanding belt is passed through the grooves between the abutments and sanding belt and ensures sufficient heat dissipation.
Das neue Schleifbandwiderlager kann für alle Bandschleif- und Poliermaschinen Verwendung finden.The new grinding belt abutment can be used for all belt grinding and polishing machines Find use.
