Description

Beschreibung.Description.

Es sind Maschinen zum Entfernen von Übermaterial, wie Angüssen u.dgl. von Stahl- und Temperguß sowie von FormguJß aus Leicht- und Schwermetallen bekannt, die einen in der vertikalen Schneidebene verschiebbaren Tragarm für eine Trennscheibe und einen senkrecht zu dieser Ebene verschiebbaren Arbeitstisch aufweisen.They are machines for removing excess material such as sprues and the like from steel and malleable cast iron as well as from Form casting from light and heavy metals known, which has a support arm that can be displaced in the vertical cutting plane for have a cutting disc and a work table that can be displaced perpendicular to this plane.

Obgleich dieses Konstruktionssystem in grundsätzlicher Hinsicht einwandfrei ist, ergab die Arbeit der- Maschinen Ungenauigkeiten, die sich zunächst nicht klären ließen.Although this construction system is more fundamental Is flawless, the work of the machines resulted in inaccuracies that could not be clarified at first.

Sorgfältige Überprüfungen haben schließlich zu der Feststellung geführt, daß zwischen den aneinander geführten Maschinenteilen trotz deren sorgfältiger Bearbeitung einCareful checks have finally led to the finding that between the abutting Machine parts despite their careful processing

gewisses Spiel bestand, das Relativbewegungen, wenn auch nur in sehr geringen Ausmaßen, und damit ein nachteiliges Vibrieren der Trennscheibe zuließ. Aus dieser Erkenntnis ergab sich die Aufgabe, den Mangel zu vermeiden, und dies ist in vollkommener Weise gemäß der Neuerung dadurch möglich geworden, daß den Führungen des Arbeitstisches und des Tragsie
arms je eine· während desThere was a certain amount of play that allowed relative movements, even if only to a very small extent, and thus a disadvantageous vibration of the cutting disc. From this knowledge the task arose of avoiding the defect, and this has become possible in a perfect way according to the innovation by the fact that the guides of the work table and the Tragsie
arms each one · during the

arms each have a clamping device that relieves the load

Eine einfache Ausführungsform der Neuerung besteht darin, daß eine Führungsnut am einen Teil von dem Kolben eines am anderen Teil gelagerten und nur während des Tischvorschubs entlasteten Hydraulikzylinders hintergriffen ist.A simple embodiment of the innovation consists in that a guide groove on one part of the piston of a bearing on the other part and relieved only during the table feed Hydraulic cylinder is engaged from behind.

Hierbei ist es vorteilhaft, daß die hinterschnittene Führungsnut am Maschinenkörper und der Hydraulikzylinder am Arbeitstisch vorgesehen sind.It is advantageous that the undercut guide groove on the machine body and the hydraulic cylinder on Work table are provided.

Ebenso ist es zweckmäßig, daß auf dem Maschinenkörper als Führung für einen Schlitten des Tragarmes der Trennscheibe ein Wellenpaar gelagert ist, und daß gegen jede dieser beiden Wellen als Spannvorrichtung ein gegenläufiges Kolbenpaar von Hydraulikzylindern wirkt, die am Tragarm gelagert sind.It is also useful that on the machine body as Guide for a carriage of the support arm of the cutting disc, a pair of shafts is mounted, and that against each of these two Shafts as a clamping device act as an opposing pair of pistons of hydraulic cylinders that are mounted on the support arm.

Anhand der Zeichnung ist die Neuerung beispielsweise erläutert.The innovation is explained using the drawing, for example.

Die DruckEittelleitungen Ih, "'5 sind über d^s .jeweilige Betätig\mgsventil für die Verstellung des Arbeitstisches und mit dem für die Verstellung des Trenr.arnschlittens verbunden.The pressure central lines Ih, "'5 are about the respective Activate \ mgsventil for the adjustment of the work table and connected to the one for adjusting the door slide.

Sobald der Arbeitstisch seitlich verschoben werden soll, wird der Hvdraulikkolben 7 beaufschlagt, die Spannscheiben 8 lösen sich vom Maschinenkörper 1.As soon as the work table is to be shifted sideways, the hydraulic piston 7 is acted upon, the clamping disks 8 detach themselves from the machine body 1.

Nach erreichter Einstellung gehen die Verstellventile selbsttätig in ihre O-Stellung zurück, vomit bewirkt wird, daß der Öldruck voll auf die Spannkolben wirkt und damit eine absolute Arretierung von Arbeitstisch und Trennarmschlitten erreicht wird.If the dividing area should graze steeply, they loosen the pistons 12 by actuation; of the corresponding valve. After the setting has been reached, the adjustment valves operate automatically back to their O position, vomit causes the Oil pressure acts fully on the clamping piston and thus achieves an absolute locking of the work table and cutting arm slide will.
