Description
Die Erfindung betrifft eine Rüttelvorrichtung und ein Verfahren zum Entfernen des Kernsandes aus hohlen Gussstücken mittels einer Rüttelvorrichtung nach der im Oberbegriff von Patentanspruch 1 näher definierten Art.The invention relates to a vibrating device and a method for removing the core sand from hollow castings by means of a vibrating device according to the closer defined in the preamble of claim 1. Art.
Eine derartige Rüttelvorrichtung ist z. B. in der
Des Weiteren ist aus der
Es ist daher Aufgabe der vorliegenden Erfindung, eine Rüttelvorrichtung und ein zugehöriges Verfahren zum Entfernen des Kernsandes aus hohlen Gussstücken dahingehend zu verbessern, dass ein schnelles und vollständiges Entfernen des Kernsandes unter günstigen ergonomischen Bedingungen für die Bedienperson möglich ist.It is therefore an object of the present invention, a vibrator and an associated method for removing the core sand from hollow castings to the effect To improve that a quick and complete removal of the core sand under favorable ergonomic conditions for the operator is possible.
Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung mit den in Anspruch 1 genannten Merkmalen und durch ein Verfahren mit den in Anspruch 15 genannten Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.According to the invention this object is achieved by a device having the features mentioned in claim 1 and by a method having the features mentioned in
Da sich der die Aufnahmeeinrichtung für das Gussstück aufweisende Teil der Rüttelvorrichtung erfindungsgemäß im Gestellrahmen drehen lässt, kann das in der Aufnahmeeinrichtung festgelegte Gussstück von seiner Klopfstellung zum Ablösen des Kernsandes in eine Ausschüttstellung für den abgelösten Kernsand gedreht werden, ohne dass die Spanneinrichtung vorher umständlich gelöst werden müsste. Hierdurch ergibt sich eine vereinfachte Handhabung der Rüttelvorrichtung für deren Bedienperson bzw. für einen zur Automatisierung eingesetzten Roboter. Unter Klopfstellung wird hierbei die Ausgangsposition des Gussstücks verstanden, in der die Ausgießöffnung des Gussstücks nach oben oder zur Seite gewandt ist, was in Abhängigkeit der Gestalt des Gussstücks und der Lage des Hohlraums variieren kann. Unter Ausschüttstellung wird demgegenüber eine Position des Gussstücks verstanden, in der die Hohlraumöffnung des Gussstücks nach unten gewandt ist, so dass der Kernsand unter Schwerkrafteinfluss und insbesondere unter der Einwirkung von Vibrationen restlos aus dem Hohlraum des Gussstücks herausfallen bzw. herausrieseln kann.Since the receiving device for the casting having part of the vibrator can rotate according to the invention in the frame, the fixed in the receiving device casting can be rotated from its knocking position for detachment of the core sand in a discharge position for the detached core sand without the clamping device are solved before cumbersome would. This results in a simplified handling of the vibrator for the operator or for a robot used for automation. By knocking is here understood the initial position of the casting, in which the pouring of the casting is turned upwards or to the side, which may vary depending on the shape of the casting and the position of the cavity. By discharge, on the other hand, a position of the casting is understood in which the cavity opening of the casting is turned downwards, so that the Kernsand under the influence of gravity and in particular under the action of vibration completely fall out of the cavity of the casting or trickle out.
Vorzugsweise verläuft die Drehachse des drehbeweglichen Teils der Rüttelvorrichtung annähernd horizontal, da das Gussstück hierdurch während seiner Drehung innerhalb einer vertikalen Querebene der Rüttelvorrichtung verbleibt. Hierdurch bleibt die Zugänglichkeit des Gussstücks für die Bedienperson während der Drehung erhalten und das Gussstück muss mittels der Spanneinrichtung nur in einer Ebene festgelegt werden, was mit einfacheren Spannelementen möglich ist.Preferably, the axis of rotation of the rotatable part of the vibrator device is approximately horizontal, as the casting thereby remains within a vertical transverse plane of the vibrator during its rotation. As a result, the accessibility of the casting for the operator during rotation is maintained and the casting must be fixed by means of the clamping device in one plane, which is possible with simpler clamping elements.
Vorteilhaft ist die den Gusskern enthaltende Hohlraumöffnung des Gussstücks in der Ausschüttstellung in eine Stellung überführt, in der sie nach unten gewandt ist.Advantageously, the casting core containing cavity opening of the casting is transferred in the discharge position in a position in which it is turned down.
Eine sehr stabile Lagerung des drehbeweglichen Teils der Rüttelvorrichtung wird möglich, wenn dieser als Trommel ausgebildet ist, die über Drehteller an ihren Trommelenden auf entgegengesetzten Seiten am Gestellrahmen gelagert ist.A very stable storage of the rotatable part of the vibrator is possible if this is designed as a drum which is mounted on turntables at their drum ends on opposite sides of the frame frame.
Um unter den rauen Betriebsbedingungen der Rüttelvorrichtung eine sehr robuste Lagerung der Trommel zu erreichen, ist diese vorzugsweise über Führungsrollen gelagert, die über den Umfang der Drehteller verteilt angeordnet sind und die zugeordneten Drehteller am Außenumfang führen. Für den motorischen Drehantrieb der Trommel ist ein ebenfalls sehr robuster Kettentrieb besonders geeignet.In order to achieve a very robust storage of the drum under the harsh operating conditions of the vibrator, this is preferably via guide rollers mounted, which are arranged distributed over the circumference of the turntable and lead the associated turntable on the outer circumference. For the motorized rotary drive of the drum is also a very robust chain drive particularly suitable.
Um in der Rüttelvorrichtung durch Vibrationsmotoren gegenläufig wirkende Massenschwingungen erzeugen zu können, sind einer oder mehrere Vibrationsmotoren der Trommel über einen Zwischenrahmen elastisch gegenüber dem Gestellrahmen aufgehängt.In order to produce in the vibrator by vibrating motors counteracting mass vibrations, one or more vibratory motors of the drum via an intermediate frame are elastically suspended from the frame frame.
Eine bequeme Zugänglichkeit der Aufnahme für das Gussstück ergibt sich, wenn die Aufnahme auf einer zugänglichen Stirnseite eines Drehtellers der Trommel angeordnet ist. Das Gussstück lässt sich auf einfache Weise durch Aufsetzen auf zwei Tragkonsolen in die Aufnahme der Rüttelvorrichtung stellen, die im Abstand voneinander aus dem Drehteller der Trommel herausstehen. Vorteilhaft wird das Gussstück durch einen mit einer Hilfskraft schwenkbeweglichen Spannhebel, in seine Auflagestellung auf den Konsolen niedergedrückt. Aufgrund der relativ kleinen Querschnitte der beiden Konsolen und des gegenüberliegenden Spannhebels wird das Ausfließen des Kernsandes aus dem Gussstück in keiner Drehstellung der Trommel nennenswert behindert.A convenient accessibility of the receptacle for the casting is obtained when the receptacle is arranged on an accessible end face of a turntable of the drum. The casting can be easily put by placing it on two support brackets in the recording of the vibrator, which protrude at a distance from each other from the turntable of the drum. Advantageously, the casting is depressed by a pivotable with an auxiliary power clamping lever in its resting position on the consoles. Due to the relatively small cross sections of the two consoles and the opposite clamping lever, the outflow of the core sand from the casting in any rotational position of the drum is significantly impeded.
Damit automatisch eine richtige Zuordnung des Klopfhammers bzw. der Klopfhämmer zum festgelegten Gussstück erfolgt, ist jeder Klopfhammer der Rüttelvorrichtung unter Zuordnung zur Gussstückaufnahme mitdrehend am Drehteller angeordnet. Gerade bei schlagempfindlichen Gussstücken ist es zweckmäßig, anstelle eines schweren Klopfhammers mehrere leichte, parallel arbeitende Klopfhämmer zu verwenden. Bei bekannten Pneumatikhämmern nach dem Stößelprinzip besteht wegen ihrer schlanken Bauweise problemlos die Möglichkeit, der Aufnahme für das Gussstück zwei, drei oder auch mehr Klopfhämmer zuzuordnen.Thus automatically a correct assignment of the knocking hammer or the hammer to the specified casting takes place, each rapping hammer of the vibrator is arranged co-rotating with the casting holder on the turntable. Especially with shock-sensitive castings, it is expedient to use instead of a heavy knocking hammer several light, parallel-acting knock hammers. In known pneumatic hammers on the plunger principle is due to their slim design easily the opportunity to assign the recording for the casting two, three or more knock hammers.
Um die Herstellkosten für die Rüttelvorrichtung gering zu halten, wird der tragende Rahmen des Gestell vorzugsweise quaderförmig gestaltet und aus abgelängten Halbzeugprofilen zusammengesetzt. Für den Gestellrahmen besonders geeignet sind geschlossene Hohlprofile, wobei Vierkantprofile z. B. durch Schraub- oder auch durch Schweißverbindungen besonders problemlos und sauber zu fügen sind.In order to keep the manufacturing costs for the vibrator low, the supporting frame of the frame is preferably cuboid shaped and composed of cut to length semifinished profiles. For the frame frame are particularly suitable closed hollow sections, with square profiles z. B. by screw or by welding joints are particularly problem-free and clean to add.
Durch die erfindungsgemäße Rüttelvorrichtung wird ein neues Verfahren zum Entfernen des Kernsandes aus hohlen Gussstücken möglich, das eine deutlich schnellere Entkernung des Gussstücks ermöglicht als herkömmliche Verfahren, bei denen das Gussstück nur gehämmert und gerüttelt wird. Dieser Vorteil liegt darin begründet, dass das Gussstück nicht mehr umgespannt werden muss, sondern bis zum Abschluss der Entkernung in seiner Aufnahme verbleibt. Durch das Drehen der Trommel entstehen auch keine Zeitverluste, wenn während der Drehung der Trommel gleichzeitig gerüttelt wird. Möglicherweise kann die Trommel aber auch bereits in der letzten Klopfphase gedreht werden, um die Effizienz des Verfahrens weiter zu steigern.By means of the vibrating device according to the invention, a new method for removing the core sand from hollow castings is made possible, which enables a much faster gutting of the casting than conventional methods in which the casting is only hammered and shaken. This advantage is due to the fact that the casting does not have to be re-clamped, but remains in its receptacle until completion of the guttering. By turning the drum arise no loss of time if shaken during the rotation of the drum at the same time. However, it may also be possible to rotate the drum in the last knock phase in order to further increase the efficiency of the process.

Durch eine Öffnung im Drehteller 15, die im unteren Bereich angeordnet ist, stehen zwei Tragkonsolen 16 aus der Trommel 14 heraus, die sich auf gleicher Höhe befinden aber in einem seitlichen Abstand voneinander angeordnet sind. Mit ihrer überwiegenden Länge befinden sich die Tragkonsolen 16 dabei in der Nische, die am Umfang vom Portal aus Vierkantrohr begrenzt ist. Auf die Tragkonsolen 16 ist ein hohles Gussstück 17, z.B. ein Zylinderkopf aufgesetzt, dessen Gusskern aus Formsand entfernt werden soll. Oberhalb des aufgesetzten Gussstücks 17 ist ein Endbereich eines Spannhebels 18 zu sehen, der zum Festlegen des Gussstücks 17 mittels eines Spannvorganges nach unten verfahren werden kann. Hierzu dient ein doppeltwirkender Pneumatikzylinder 19, durch dessen Ansteuerung der Spannhebel 18 in der vertikalen Ebene zwischen den Tragkonsolen 16 zum Festlegen und Lösen des Gussstücks 17 in entgegengesetzten Richtungen geschwenkt werden kann. Oberhalb der Spanneinrichtung sind am Drehteller 15 zwei pneumatische Klopfhämmer 20 angeordnet, deren als Hammerkopf dienende Stößel senkrecht nach unten auf das Gussstück 17 gerichtet sind. Durch pulsierendes Ausfahren der Klopfhammerstößel und Auftreffen derselben am Gussstück, wird das Gussstück 17 somit in bekannter Weise geklopft, wodurch der Gusskern nach einiger Zeit mittelbar zu mehr oder weniger groben Brocken zerschlagen wird.Through an opening in the

Die Führungsrollen 24 stehen von der inneren Breitseite der Tragplatte 13 bzw. 13' ab und umgreifen den Umfang des zugeordneten Drehtellers 15 bzw. 15'. Der zylindrische Schaft der Führungsrollen 24 besteht hier aus drehbaren Lagerhülsen und wälzt sich dadurch beim Drehen der Drehteller 15 bzw. 15' auf dem Umfang des zugeordneten Drehtellers 15 bzw. 15' ab. Als Antriebsmittel für die Trommel 14 dient ein robuster Kettenantrieb. Hierzu ist der Drehteller 15' mit einem Zahnring versehen, auf dem eine ihn umschlingende Rollenkette 25 läuft, die ihrerseits von einem Ritzel 26 angetrieben wird. Das Ritzel 26 ist in einem Abstand oberhalb des Drehtellers 15' auf der Tragplatte 13' angeordnet, wodurch die Rollenkette 25 über Kettenspanneinrichtungen straff gespannt gehalten ist.In order to achieve a robust pivot bearing of the
