KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Vorrichtungen zum Pressen von Betonrohren u. dgl. ist es wichtig, einen Formverschluß zu haben, der schnell in die Verschlußlage gebracht werden kann und außerdem ein Lockern der Verschlußschrauben möglichst ausschließt. Nach der Erfindung wird dies dadurch erreicht, daß die Form durch Schrauben zusammengehalten wird, deren Muttern sich in Gehäusen befinden, in welchen gleichzeitig ίο Exzenter lagern, durch deren Drehung um 90° die Form geschlossen wird.In devices for pressing concrete pipes and the like, it is important to have a mold fastener that quickly moves into the closed position can be brought and also excludes a loosening of the screw plugs as possible. According to the invention this is achieved in that the form is held together by screws, the nuts of which are in housings in which ίο eccentrics are stored at the same time, by rotating them by 90 ° the mold is closed.
In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und
zwar zeigt
Fig. ι den Verschluß im Gebrauch, währendIn the drawing, an embodiment of the subject invention is shown, namely shows
Fig. Ι the closure in use while
Fig. 2 und 3 Einzelheiten des Verschlusses in vergrößertem Maßstab wiedergeben.FIGS. 2 and 3 show details of the closure on an enlarged scale.
Zum Verschluß dient eine Schraube 1, deren Mutter 2 in einem Gehäuse 3 verschiebbar gelagert ist. In dem Gehäuse 3 ist ferner drehbar ein Exzenter 4 gelagert, welches durch eine Aussparung im äußeren Ende der Mutter hindurchragt.A screw 1, the nut 2 of which is displaceable in a housing 3, is used for the closure is stored. In the housing 3, an eccentric 4 is also rotatably mounted, which by a recess in the outer end of the nut protrudes.
Soll nun die Form geschlossen werden, so wird die Schraube 1, welche einen länglichen Kopf hat, durch das entsprechend länglich gestaltete Loch 5 der Flanschen 6, 7 der Rohrform hindurchgesteckt und sodann um 90° gedreht, so daß der Kopf quer zu dem Loch 5 liegt. Hierauf wird das Exzenter 4 um 90° gedreht, so daß es in die in den Fig. 2 und 3 in vergrößertem Maßstabe gezeichnete Lage gelangt und dadurch die Form fest verschließt. Durch die Drehung des Exzenters 4 um 90° wird die Mutter 2 mit der Mutter 1 dem Gehäuse 3 gegenüber in achsialer Richtung verschoben, und zwar wird das Gehäuse 3 gegen die Flanschen 6 gepreßt und die Mutter 2 von diesen entfernt, wodurch das feste Zusammenziehen der Flanschen 6, 7 unter Vermittlung der Schraube 1 bewirkt wird.If the mold is now to be closed, the screw 1, which has an elongated Head has, through the corresponding elongated hole 5 of the flanges 6, 7 of the tubular shape inserted through it and then rotated by 90 ° so that the head is transverse to the hole 5 lies. The eccentric 4 is then rotated through 90 ° so that it is in the positions shown in FIGS Arrives at an enlarged scale drawn position and thereby tightly closes the form. By rotating the eccentric 4 by 90 °, the nut 2 with the nut 1 is the Housing 3 is displaced opposite in the axial direction, specifically the housing 3 pressed against the flanges 6 and the nut 2 removed from these, whereby the solid Contraction of the flanges 6, 7 is effected by means of the screw 1.
