Description
Verfahren und Vorrichtung zur Aufbereitung von Formsand und zur Herstellung von Formen für Massenguß. Zusatz Patent 4zq422*j. Nach dem Patent 414422 erfolgt die Aufbereitung des Sandes und die Herstellung der Herdformen auf maschinellem Wege absatzweise nacheinander in der Weise, daß eine die Formmodelle tragende Platte oder Tisch auf den Formsand aufgesetzt und sich infolge Eigengewichts eindrücken soll. Die Praxis hat nun gezeigt, daß das Eindrücken auf große Flächen nicht oder nicht gleichmäßig vor sich geht, wenn man nicht zu übergroßen Gewichten kommen will.Method and device for the preparation of molding sand and for its production of molds for mass casting. Addition patent 4zq422 * j. According to the patent 414422 done the preparation of the sand and the production of the stove forms on machine Paths in steps one after the other in such a way that a plate carrying the shape models or table placed on the molding sand and pressed in due to its own weight target. Practice has now shown that pressing on large areas is not or does not proceed evenly if one does not want to get too heavy weights.
Gemäß der Erfindung werden nun die von dem Tisch verschiebbar getragenen Modelle nacheinander in das Bett eingeschlagen oder eingepreßt. Infolgedessen wird die ganze Anlage leichter und stellt sich billiger. *) Früheres Zusatzpatent 4i6959. In der Zeichnung ist in Abb. i eine Seitenansicht und in Abb. 2 eine Aufsicht einer Ausführungsform dargestellt, wobei die Teile zur Aufbereitung des Formsandes weggelassen sind.According to the invention, the slidably carried by the table are now Models hammered or pressed into the bed one after the other. As a result, will the whole system lighter and cheaper. *) Former additional patent 4i6959. In of the drawing is in Fig. i a side view and in Fig. 2 a plan view of a Embodiment shown, with the parts for processing the molding sand omitted are.
In dem die Modelle tragenden Tisch 39 ist ein Längsschnitt 40 vorgesehen, von dem eine Anzahl Längsschlitze 41 senkrecht abzweigen, und die zusammen der Form einer Muttermassel mit anhängenden Töchtermasseln entsprechen. Diese Schlitze dienen zur Führung der Modelle 42, die T-förmig derart gestaltet sind, daß sie eine Tochtermassel und ein anhängendes Stück Muttermassel bilden und gewissermaßen eine Taste darstellen. Alle Tasten zusammen entsprechen dem ganzen Masselkamm. Die Tasten können durch einen Hammer 43 einzeln nacheinander in den Sand eingedrückt werden. Selbstverständlich kann man den Hammer auch durch eine Vorrichtung ersetzen, welche hydraulisch, mechanisch oder sonstwie die einzelnen Tasten eindrückt. Auch kann eine Taste mehrere Formen bilden. An sich ist die Anordnung von Modellen nach Art von Tasten bekannt, jedoch werden hierbei in üblicher Weise Modelle, Modellplatten, Formkästen und Formkästenaufsätze verwendet.A longitudinal cut 40 is provided in the table 39 carrying the models, from which a number of longitudinal slots 41 branch off vertically, and together form the shape correspond to a mother's bill with attached daughter's bill. These slots serve to guide the models 42, which are T-shaped in such a way that they are a daughter pig and form an attached piece of chuck and, in a sense, represent a key. All buttons together correspond to the whole pig comb. The buttons can go through a hammer 43 are pressed one after the other into the sand. Of course you can replace the hammer with a device that is hydraulic, mechanical or otherwise press the individual buttons. A button can also have multiple forms form. The arrangement of models in the manner of buttons is known per se, however are here in the usual way models, model plates, molding boxes and molding box attachments used.
