Description

1. Die Neuerung besteht in der Verwendung eines zweiten, endlosen, aus elastischem Material bestehenden Transportbandes als Unterlage für das Schleifband.1. The innovation consists in the use of a second, endless, conveyor belt made of elastic material as a base for the sanding belt.

Der Unterschied gegenüber anderen, bisher bestehenden Bandschleifmaschinen besteht darin, daß nicht das zu schleifende Werkstück auf das Schleifband an einer Scheibe angedrückt, sondern in das zwischen den Rollen i und 2 von dem elastischen Tragband unterstützte Schleifband eingedrückt wird.The difference compared to other, previously existing belt grinders is that not the workpiece to be sanded on the sanding belt at one Washer pressed, but in that between the rollers i and 2 of the elastic Belt supported sanding belt is pressed in.

Durch diese Neuerung wird ein weitgehendstes Anschmiegen des Schleifbandes an das Werkstück erreicht und kann selbst bei hohem Schleifdruck das Schleifband nicht zerreißen.This innovation ensures that the sanding belt snuggles to the greatest possible extent reaches the workpiece and can use the sanding belt even with high sanding pressure don't tear.

Der Vorteil dieser Neuerung, die insbesondere zum Schleifen von zylindrischen oder ähnlich profilierten geraden oder gebogenen Werkstücken (Rohre, Stangen, Geländerschienen usw.) aus beliebigem Material Anwendung findet, zeigt sich in einer wesentlichen Verkürzung der Schleifzeiten bei schönem, gleichmäßigem Schliff. Außerdem wird Einsparung am Verbrauch der Schleifbänder infolge Herabminderung der Zerreißgefahr und größtmöglichste Abnutzungsdauer derselben ereicht.The advantage of this innovation, which is particularly useful for grinding cylindrical or similarly profiled straight or curved workpieces (pipes, rods, handrail rails etc.) is used from any material, shows itself in an essential one Shortening of the sanding times with beautiful, even sanding. It will also save on the consumption of the grinding belts as a result of reducing the risk of tearing and as much as possible Wear life of the same reached.

Es ist zwar die Verwendung eines starren Transportbandes für das Schleifband in Form eines Stahlbandes bei Bandschleifmaschinen bekannt; im Gegensatz hierzu wird erfindungsgemäß bei Verwendung eines aus elastischem, dehnbarem Material bestehenden Tragbandes eine wesentliche Verbesserung der bisher bestehenden Bandschleifmaschinen zum Schleifen von zylindrisch porfilierten Werkstücken verschiedenster Form erzielt.Although it is the use of a rigid conveyor belt for the sanding belt known in the form of a steel belt in belt grinders; in contrast to this is according to the invention when using an existing made of elastic, stretchable material Carrying belt is a significant improvement on the belt sanding machines that have existed up to now for grinding cylindrically pored workpieces of various shapes.

11. Die durch obige Erfindung sich ergebenden wirtschaftlichen und praktischen Vorteile werden durch die schematischen Aufzeichnungen der Bandschleifmaschine (s. Zeichnung) aufgezeigt.11. The economic and practical advantages are provided by the schematic recordings of the belt grinder (see drawing).

Auf einem Stahlblech- oder Graugußmaschinengehäuse ist das Laufwerk für das Schleifband und die elastische Bandunterlage in Form eines Dreisclleibensystems, wovon die Scheibe 2 starr mit dem Antriebsmotor verbunden ist, aufgebaut.The drive is on a sheet steel or cast iron machine housing for the sanding belt and the elastic belt underlay in the form of a three-wheel system, of which the disc 2 is rigidly connected to the drive motor.

a) Die Zugkräfte, die durch die Antriebsscheibe 2 entstehen, werden von der über die bewegliche Scheibe i mitlaufenden elastischen Bandunterlage 4 auf das Schleifband 5 übertragen. Durch die große Mittiehmerfläche der elastischen Bandunterlage wird die Zerreißgefahr gegenüber den ohne elastische Schleifunterlage getriebenen Bandschleifmaschinen um ein Vielfaches herabgemindert.a) The tensile forces created by the drive pulley 2 are from the elastic band support 4 moving along with the movable disk i the sanding belt 5 transferred. Due to the large contact area of the elastic band underlay the risk of tearing is increased compared to those without an elastic sanding pad Belt grinders reduced many times over.

b) Durch die elastische Bandunterlage 4 kann auf das Schleifband 5, welches über den oberen Teil desselben, zwischen Scheibe i und 2 und der ebenfalls beweglichen Scheibe 3 läuft, das zu schleifende Werkstück 6 mit Druck zwischen Scheibe i und 2 angepreßt werden. Die Schleifwirkung wird durch <die größere Schleiffläche und den gleichzeitig möglichen größeren Schleifdruck, gegenüber der Nichtverwendung der elastischen Bandunterlage, wesentlich erhöht, ohne daß eine Zerreißgefahr für das Schleifband entsteht.b) Through the elastic belt pad 4, the sanding belt 5, which over the upper part of the same, between disk i and 2 and the also movable disk 3 runs, the workpiece to be ground 6 with pressure between the disk i and 2 are pressed. The grinding effect is enhanced by <the larger grinding surface and at the same time possible higher grinding pressure, compared to not using it the elastic band base, significantly increased without the risk of tearing the sanding belt is created.

c) Das Schleifband verdehnt sich an den Seiten nicht, wird dadurch an den Rändern nicht verfranst, rollt von den Laufscheiben nicht ab und kann nicht zerreißen, was bei allen anderen bekannten Schleifmaschinen sonst der Fall ist. ' d) Durch die Dehnbarkeit der elastischen Bandunterlage, welche durch die bewegliche Rolle i gespannt ist, kann das Schleifband 5, welches seinerseits@ durch die bewegliche Rolle 3 auf der Bandunterlage gespannt gehalten wird, beim Schleifen zwischen Rolle i nach der einen oder anderen Seite verkantet werden.c) The sanding belt does not stretch on the sides, it will Does not fray at the edges, does not roll off the pulleys and cannot tear, which is otherwise the case with all other known grinding machines. 'd) Due to the elasticity of the elastic band base, which is due to the movable Roll i is stretched, the sanding belt 5, which in turn @ by the movable Roll 3 is held taut on the belt support when sanding between roll i be tilted to one side or the other.
