Description
Maschine zur Herstellung von Gegenständen aus pulverförmigen Preßmassen Es sind Maschinen zur Herstellung von Gegenständen auspulverförmigenPreßmassen, z. B. Kunsthorn, bekannt, bei denen Formen mit abgemessenen Mengen des Preßpulvers in ununterbrochener Folge durch ein Rohr hindurchgepreßt werden, das durch eine Heiz-und anschließende Kühlvorrichtung geführt ist. -Gemäß der Erfindung werden bei einer solchen Maschine die Preßpulver aus einem oder mehreren Fülltrichtern unter Vermittlung einer Mischschnecke in die in einem sich absatzweise drehenden Formtisch befindliche Form gefüllt, welche durch Drehung des Formtisches vor die Mündung des Preßrohres gelangt, in das sie durch einen Preßstempel hineingepreßt wird, während die letzte im Preßrohr befindliche Form durch eine federnde Hülse festgehalten wird, die sich beim Einpressen der nächsten Form öffnet.Machine for the production of objects from powder molding compounds They are machines for the production of objects from powdered molding compounds, z. B. artificial horn, known in which forms with measured amounts of the molding powder be pressed in uninterrupted sequence through a pipe that is passed through a Heating and subsequent cooling device is performed. -Be according to the invention in such a machine the molding powder from one or more filling hoppers with the mediation of a mixing screw in the one that rotates intermittently Mold table located form filled, which by rotating the mold table in front of the Mouth of the press tube reaches into which it is pressed by a ram is, while the last form located in the compression tube by a resilient sleeve that opens when the next mold is pressed in.
Die Maschine nach der Erfindung ermöglicht eine automatische Herstellung von Gegenständen, z. B. Knöpfen, aus pulverförmigen Preßmassen, wie Kunsthorn u. dgl. In der Zeichnung ist eine Ausführungsform der Erfindung veranschaulicht, und zwar zeigt: Fig. i einen Vertikalschnitt, Fig. a einen Horizontalschnitt, Fig.3 eine Einzelheit und Fig.4 eine Ansicht des Formtisches.The machine according to the invention enables automatic production of objects, e.g. B. buttons, made of powdered molding compounds, such as artificial horn u. Like. In the drawing, an embodiment of the invention is illustrated, and although it shows: FIG. i a vertical section, FIG. a a horizontal section, FIG. 3 a detail and FIG. 4 a view of the molding table.
Aus zwei getrennt liegenden Behältern k und .o (Fig. i) werden verschiedene gefärbte Pulver in einen kleinen gemeinsamen Trichter a befördert, welcher durch eine Mittelwandr bis zu einer bestimmten Tiefe geteilt ist. Von dort gelangen die Pulver zur Mischschnecke b, welche sie mischt und die Formen e im Formtisch d füllt, wodurch eine ganz natürliche Maserung erreicht wird. Durch eine Drehung des Formtisches d wird die Form vor die Öffnung des Führungsrohres lt gestellt, dessen Anfang durch eine Federhülse l nach dem Formtisch d hin verlängert ist, welche durch den geschlitzten Vorderteil die eingepreßte Form c festhält, bei jeder neu eingepreßten Form c sich öffnet und nach Eintritt sich selbst schließt und so den Rückdruck der Formen im Führungsrohr aufnimmt.Two separate containers k and .o (Fig. I) become different colored powder is conveyed into a small common hopper a, which passes through a middle wall is divided to a certain depth. From there the Powder for the mixing screw b, which mixes it and fills the molds e in the molding table d, whereby a completely natural grain is achieved. By turning the forming table d the mold is placed in front of the opening of the guide tube lt, the beginning of which is through a spring sleeve l is extended towards the mold table d, which through the slotted Front part holds the pressed-in shape c, with each newly pressed-in shape c opens and after entry closes itself and so the back pressure of the forms in the Takes up guide tube.
Zum ununterbrochenen Betrieb dient Formtisch d (Fig. z und 4), welcher in seinen Bohrungenjt eine leere Formc aufnimmt, sie in die Füllstellung vor die Mischschnecke b bringt und die gefüllte Form vor die Öffnung des Führungsrohres lt (Fig. z) stellt. Beim Dauerbetrieb befinden sich drei Formen c im Formtisch d, eine leere, eine zum Füllen und eine gefüllte. Die gefüllten Formen werden durch den Preßstempela absatzweise in an sich bekannter Art im Führungsrohr zu einer Säule zusammengestellt und durch die Heiz-und Kühlvorrichtung hindurchgeschoben.Forming table d (Fig. Z and 4), which is used for uninterrupted operation takes an empty form in its bores, it in the filling position in front of the Mixing screw b brings and the filled form in front of the opening of the guide tube lt (Fig. z) represents. In continuous operation there are three forms c in the forming table d, an empty one, one for filling and one filled. The filled shapes are through the Preßstempela intermittently in a known manner in the guide tube to a column put together and pushed through the heating and cooling device.
