Abstract

For fully automatic screwing together of foundry cores, partic. base (1) and water jacket (2) cores, screws (5) are conveyed to a screwdriver (6) via a hose (8) from a separating and feeding device (4). The screws are driven at adjustable torque in to the cores, held in a gripping device (3) above the screwdrivers. The position of the screwdrivers can be adjusted by spindles (7). ADVANTAGE - Cores can be associated immediately after mfr.

Description

Die Erfindung bezieht sich auf eine Schraubvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a screw device according to the preamble of claim 1.

Das Formen der Kerne in der Gießereitechnik erfolgt von Hand oder mit Hilfe von Kernformmaschinen in besonderen mehr­ teiligen Kernkästen oder Kernbüchsen. Die Kernherstellung er­ folgt im allgemeinen durch Kernblasen, Kernstopfen und Kern­ schießen. Die Vereinigung oder Zusammenführung der Kerne er­ folgt in getrennten Vorgängen, so daß das Herstellungsverfah­ ren als sehr umständlich, arbeitsintensiv und zeitraubend an­ gesehen werden kann.The cores in foundry technology are formed by Hand or with the help of core molding machines in special more part core boxes or core boxes. The core manufacturing he follows generally by core blisters, core plugs and core shoot. The union or merging of the cores follows in separate processes so that the manufacturing process are very cumbersome, labor intensive and time consuming can be seen.

Aus der DE-PS 35 26 265 ist eine Kern-Paketiermaschine für den vollautomatischen Zusammenbau von gießfertigen Kern­ paketen bekannt, die gekennzeichnet ist durch eine Entnahme­ vorrichtung zum Austragen der Kerne aus der Kernschießmaschi­ ne, eine Schwenkvorrichtung zum gemeinsamen Hochschwenken der Kerne, ein Klebstoffauftragssystem, eine Paketiervorrichtung. Die Unterlagen des deutschen Gebrauchsmusters 75 15 919 beziehen sich auf eine Vorrichtung zum Verbinden mehrteiliger, wärmeaushärtbarer Gießkerne mittels Metallstiften mit einer mit Indexmitteln zur definierten Aufnahme wenigstens eines ersten Kernteiles versehenen Arbeitsplatte, sowie mit einer auf die Arbeitsplatte absenkbaren, definiert geführten, vor­ zugsweise mit weiteren Indexierungsmitteln versehenen Gegen­ platte, die dadurch gekennzeichnet ist, daß an der Gegenplatte wenigstens eine auf Nagelpreßsitz in den noch heißen Kerntei­ len ausgelegten Nagelmaschine angeordnet ist, deren Nagelaus­ tritt entsprechend von Durchtrittsöffnungen an den zu verbin­ denden Kernteilen ausgerichtet ist.From DE-PS 35 26 265 is a core packaging machine for the fully automatic assembly of cast-ready core known packages, which is characterized by a removal device for removing the cores from the core shooter ne, a swivel device for swiveling the Cores, an adhesive application system, a packaging device. The documents of the German utility model 75 15 919 relate to a device for connecting multi-part, heat-curable casting cores using metal pins with a with index means for the defined inclusion of at least one first core part provided worktop, as well as with a can be lowered onto the worktop in a defined manner counter with additional indexing means plate, which is characterized in that on the counter plate at least one on a press fit in the still hot core len designed nail machine is arranged, the nail out occurs accordingly from passage openings to the verbin the core parts.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, die zu vereinigenden Kerne unmittelbar von der Herstellungs­ stelle ohne irgendeine Zwischenhandhabung über die Schraub­ station zu bringen.The object of the present invention is now to the cores to be combined immediately from the manufacturing place over the screw without any intermediate handling bring station.

Die Lösung dieser Aufgabe wird durch die im Kennzeichen des Patentanspruchs 1 beschriebene technische Lehre vermit­ telt.This problem is solved by the in the indicator technical teaching described in claim 1 telt.

Zwei zu vereinigende Kerne werden mittels einer Greif­ vorrichtung über einen pneumatisch arbeitenden Schrauber gebracht und mit Hilfe von Schrauben miteinander verbunden, die durch ein Vereinzelungs- und Einschießgerät einge­ bracht werden.Two cores to be merged are gripped together device via a pneumatic screwdriver brought and connected with the help of screws, turned on by a singling and shooting device be brought.

Der gesamte Prozeß ist vollautomatisch verkettet von der Einzelherstellung der Kerne bis zur Ablage der zusammen­ gefügten und verschraubten und geschwärzten Kerne auf das Transportband der Trockenöfen.The entire process is automatically linked by the individual production of the cores up to the storage of the joined and screwed and blackened cores on the Conveyor belt for drying ovens.

Die Zeichnungen erläutern in Verbindung mit der nach­ folgenden Beschreibung eine Ausführungsform der Erfindung. The drawings explain in conjunction with the following description an embodiment of the invention.  

Fig. 1 zeigt schematisch die erfindungsgemäße Schraub­ vorrichtung im Längsschnitt von der Seite gesehen, Fig. 1 shows schematically the screw device according to the invention seen in longitudinal section from the side,

Fig. 2 stellt die Vorrichtung im Schnitt in Querrich­ tung dar, Fig. 2 shows the device in section in the transverse direction is tung,

Fig. 3 zeigt die Vorrichtung von oben gesehen und Fig. 3 shows the device seen from above and

Fig. 4 stellt im Detail das Verschrauben der Kerne dar. Fig. 4 shows the screwing of the cores in detail.

Nach der Einzelfertigung von je drei Sohlen- 1 und Wassermantelkernen 2 werden diese zunächst automatisch lose miteinander vereinigt. Danach werden sie von der Greifvor­ richtung 3 ergriffen und verspannt über die Schraubvorrich­ tung transportiert.After the individual production of three sole cores 1 and two water jacket cores 2 , these are initially automatically loosely combined with one another. Then they are gripped by the Greifvor device 3 and tensioned transported over the screw device.

Es stehen nun drei verspannte Sohlen- 1 und Wasserman­ telkerne 2 über der Schraubvorrichtung. Der Abstand der Kernpakete beträgt fertigungsbedingt 220 cm.There are now three braced soles 1 and water core 2 over the screwing device. The distance between the core packages is 220 cm due to the manufacturing process.

Die Schrauben 5 werden vom Vereinzelungs- und Ein­ schießgerät 4 durch die Transportschläuche 8 in die Schrau­ ber 6 mittels Preßluft geschossen. Von diesen Schraubern 6 werden die Schrauben 5 mittels einstellbarem pneumatischem Vorschub sowie einstellbarem Drehmoment in die von der Greif­ vorrichtung 3 darüber verspannten Kerne 1, 2 eingeschraubt. Für die zwei weiteren Kernpakete wiederholt sich dieser Vor­ gang in zwei weiteren Schritten, wobei die notwendige Ver­ schiebung von 220 cm von zwei Luftzylindern 9 vorgenommen wird.The screws 5 are shot from the separating and shooting device 4 through the transport hoses 8 into the screw 6 by means of compressed air. From these screwdrivers 6 , the screws 5 are screwed by means of adjustable pneumatic feed and adjustable torque into the cores 1 , 2 braced by the gripping device 3 above them. For the two other core packages, this process is repeated in two further steps, the necessary displacement of 220 cm being carried out by two air cylinders 9 .

Danach werden die drei verschraubten Kernpakete 1, 2 von der Greifvorrichtung 3 zur Schwärzevorrichtung weiter transportiert. The three screwed core packages 1 , 2 are then transported further from the gripping device 3 to the blackening device.

Die typengebundenen Abstände der Schraubstellen werden durch die Spindeln 7 vorgenommen. Die sich je­ weils in zwei Achsrichtungen einstellen lassen.The type-specific distances between the screw points are made by the spindles 7 . Which can each be adjusted in two axial directions.
