Description
Verfahren und Vorrichtung zur Herstellung hohlzylindrischer Formlinge
mit gelochten Wandungen
Die Gestalt der Öffnungen spielt für die Ausbildung der Einrichtung keine entscheidende Rolle. Voraussetzung ist nur, daß die übergestülpte Hohlform in ihren Öffnungen den hindurchtretenden Stößeln entspricht.The shape of the openings plays a role in the design of the facility not a crucial role. The only prerequisite is that the hollow shape is put over it corresponds in their openings to the tappets passing through.
ähere Einzelheiten der neuen Einrichtung sind aus den Zeichnungen zu ersehen, in denen Abb. i eine Draufsicht auf den benutzten Fördertisch, Abb. 2 einen senkrechten Schnitt durch die Locheinrichtung entsprechend Linie II-II von Abb. i darstellen.further details of the new facility are from the drawings can be seen in which Fig. i is a top view of the conveyor table used, Fig. FIG. 2 shows a vertical section through the hole device according to line II-II of FIG Fig.i represent.
Auf der Oberfläche i des Fördertisches werden die noch ungelochten hohlzylindrischen Formlinge 2 mittels der Klauen 3, die an der endlosen Kette ,I sitzen, absatzweise weitergeschoben. Die Kette läuft um das Antriebsrad 5 und das Umlenkrad 6. Wenn ein noch ungelochter Formling an diejenige Stelle vorgerückt ist, die in der Abb. i an dem Durchtritt der Führungsstangen 7 für den Oberstempel 8 erkennbar ist, so kommt er auf einen in einer ringförmigen Aussparung des Fördertisches eingelassenen Unterstempel zu stehen. Der Unterstempel (Tragring) wird alsdann abgesenkt, und der Oberstempel folgt ihm mit kurzer Verzögerung nach.On the surface i of the conveyor table they are still unperforated hollow cylindrical bricks 2 by means of the claws 3, which are attached to the endless chain, I sit, pushed forward in sections. The chain runs around the drive wheel 5 and that Deflection wheel 6. When a molding that has not yet been perforated has advanced to the point the one in Fig. i at the passage of the guide rods 7 for the upper punch 8 can be seen, it comes to one in an annular recess of the conveyor table recessed lower stamp to stand. The lower punch (support ring) is then lowered, and the upper stamp follows it with a short delay.
Abb. 2 zeigt die Locheinrichtung mit versenktem Formling 2. Der Formling steht auf dem Unterstempel io, der von einem Gerüst i i getragen wird, das mittels eines um den Punkt 12 drehbaren Hebels 13 von dem um die Welle 14 drehbaren Exzenter 15 gehoben und gesenkt wird. Durch entsprechende Mitnehmerwird auch der Oberstempel 8 mittels der Führungsstangen 7 gesenkt und wieder angehoben.Fig. 2 shows the hole device with recessed molding 2. The molding stands on the lower stamp io, which is supported by a frame i i, which is made by means of a lever 13 rotatable about point 12 from the eccentric rotatable about shaft 14 15 is raised and lowered. Appropriate drivers also make the upper punch 8 lowered by means of the guide rods 7 and raised again.
Beim Absinken ist der Formling über eitlen Hohlzylinder 16 gestülpt worden, in dem sich Öffnungen 17 befinden, die den in dem anliegenden Formling zu erzeugenden Öffnungen entsprechen. Rings um Gien Formling verteilt befinden sich die Stößel oder Messer 18, die sich radial nach innen bewegen und dabei die aus dem Formling ausgeschnittene Masse durch die Öffnungen 17 in den innerhalb des Zylinders 16 gebildeten Hohlraum werfen, wo sie herunterfällt, um durch das schräg liegende Ablaufrohr i9 ausgetragen zu werden. Bei dem dargestellten Ausführungsbeispiel lialicn die Messer den Querschnitt eines hochkant gestellten Parallelogramms; es sind je drei 'Messer senkrecht übereinander angeordnet und am hinteren Ende an einem Messerhalter 20 befestigt. Die Bewegutig dieser rings um die Hohlform verteilte» Messerhalter geschieht dadurch, daß der eine Schenkel des um den Punkt 21 drehbaren Kniehebels 22 gelenkig mit dem Messerhalter 2o verbunden und der andere Schenkel des Kniehebels 22 an einen Hebel 23 angelenkt ist, der an dem Ring 24 sitzt. Der Ring 24 wird mittels des Gestells 23 über zwei um die Punkte 26 drehbare 1 lebel 27, die vor und hinter dem Hebel 13 liegen, mittels ebenfalls auf der Welle 14 laufender Erzenterscheiben 28 angehoben und gesenkt.As it descends, the molding has been slipped over a hollow hollow cylinder 16 in which there are openings 17 which correspond to the openings to be produced in the adjacent molding. Distributed around Gien molding are the plungers or knives 18, which move radially inward and throw the mass cut out of the molding through the openings 17 into the cavity formed within the cylinder 16, where it falls down to pass through the inclined Drain pipe i9 to be discharged. In the illustrated embodiment, the knives line the cross-section of an upright parallelogram; there are three 'knives arranged vertically one above the other and attached to a knife holder 20 at the rear end. The movement of these knife holders distributed around the hollow shape is achieved by the fact that one leg of the toggle lever 22 rotatable about point 21 is articulated to the knife holder 2o and the other leg of the toggle lever 22 is hinged to a lever 23 which is attached to the ring 24 sits. The ring 24 is raised and lowered by means of the frame 23 via two 1 lebel 27 rotatable about the points 26, which are located in front of and behind the lever 13 , by means of orner disks 28 also running on the shaft 14.
