Description

Die Erfindung betrifft eine Drehtischpresse mit durch die obere, ertsfeste Formdeckplatte in die Preßform eindringenden Lochdornen, bei der die Lochdo-rne an einem Topfkolben befestigt sind. Sie schlägt vor, die beim Hochziell-en der Dorne durrch die Bohrunge#n der Formdeckplatte eintretenden Füllgutkörner durch eine besondere Ausgestaltung der zur Führung der Dorne dienenden Formdeckplatte in Verbindung mit einer Preßluftblaseinrichtung zu entfernen.The invention relates to a turntable press with through the upper, ertsfeste Form cover plate piercing piercing mandrels in the mold, in which the piercing mandrels are attached to a pot flask. She suggests that when Hochziell-en the thorns Product grains entering through the bores of the mold cover plate through a special Design of the mold cover plate used to guide the mandrels in conjunction with to remove a compressed air blower.

. Erfin,dungsgernäß besteht die- Formdeckplatte aus deir die Preßfonn oben abschließenden Dornführungsplatte mit einem darüberliegenden Zwischenstück und erweiterten Bohrungen für die Lochdorne, einem nur auf den bohrtingsfreien Flächen des Zwischenstücks anfliegenden Keil mit Preßluftzuführungsböhrungen und einer mit einer Gegenkeilfläche versehenen weiteren Dornführungsplatte. . Invention, the mold cover plate consists of deir the Preßfonn top closing mandrel guide plate with an overlying intermediate piece and expanded holes for the piercing mandrels, a wedge with compressed air supply holes and a further mandrel guide plate provided with a counter-wedge surface only on the surfaces of the intermediate piece free from drilling.

An. Hand des in den Zeichnungen dargestellten Ausführungsbeispiels sei die Erfindung erläutert. Die obere Führungsplatte 26 weist Bohrungen zuT Führung der mit der Platte:2o am Topfkolben ig befestigten Lochdorne7 auf, ebenso die untere Dornführungsplatte 28. Das Zwischenstück :27, dessen Bollrungen aus diesem Grunde größere Durchmesser als die der beiden Führungsplatten 26 bzw. 28 haben, dient nur der Übertragung der Nachstellbewegungen des Keils:29 bei Verschleiß der Führungsplatte:28. Der Keil:29 liegt nur auf den bohrungsfreien Flächen des Zwischensfückes 27 9,u£ Durch ihn hindurch führt eine Preßluftblasvorrichtung 38, mit welcher aus der Form durch die, Bohrungen des Zwischenstücks 27 noch gezogene Füllgutkörner entfernbar sind.At. The invention will be explained using the exemplary embodiment shown in the drawings. The upper guide plate 26 has bores for guiding the piercing mandrels 7 fastened to the pot piston ig with the plate: 2o, as is the lower mandrel guide plate 28. The intermediate piece: 27, the stanchions of which have larger diameters than those of the two guide plates 26 and 28 for this reason, serves only to transfer the adjustment movements of the wedge: 29 if the guide plate is worn: 28. The wedge: 29 lies only on the bore-free surfaces of the intermediate foot 27 9, and a compressed air blowing device 38 leads through it, with which product grains that are still drawn through the bores of the intermediate piece 27 can be removed from the mold.

Das Eindringen von Füllgutkörnern. kann ferner durch besondere elastische Dichtringe 30 am unte,-ren Rand der Führungsplattenbohrungen verhindert werden.The penetration of product grains. can also be prevented by special elastic sealing rings 30 on the lower edge of the guide plate bores.

Um den Topfkolben ig bei Erreichung seiner unteren Lage weich abzufangen, sind im Pressenholm 6 elastische Pufferstücke:25- vorgesehen, auf die der Topfkolben ig mit seinem Bund 37 aufschlägt. Diese Pufferstücke können, wie die Erfind,ung weiter vorschlägt, auswechselbar ausgebildet sein, damit sich durch Wahl unterschiedlicher Stärken die Eindringtiefe, der Lochdorne 7 in die Füllmasse einstellen läßt.In order to catch the pot piston ig softly when it reaches its lower position, elastic buffer pieces are provided in the press beam 6 , on which the pot piston ig strikes with its collar 37. These buffer pieces can, as the invention further suggests, be designed to be exchangeable so that the penetration depth of the piercing mandrels 7 into the filling compound can be adjusted by choosing different thicknesses.

Sollen zwei Steine gleichzeitig gelocht und gepreßt werden, so wird nach einem weiteren Vorschlag der Erfindung die Dornführungsplatte 28 zweiteilig ausgefühTt. Die in Tischbewegungsrich-' tung vordere Platte 28" (Fig. 2) ist dabei einige Zehntelmillimeter dünner gehalten und besteht aus weicherem Material als die dahinterliegende Platte 28b- Hierdurch wird auf einfachste Weise erreicht, daß der fertig gepreßte, unter Platte 28b liegende Fonnling bei der nun folgenden Tischdrehung nicht unter Platte 28" herschleift. Infolge der unterschiedlichen MateriaJhärtv ändert sich der Dickenunterschied beider Platten auch bei Dauerbetrieb nicht merkfid-i.If two stones are to be punched and pressed at the same time, then, according to a further proposal of the invention, the mandrel guide plate 28 is designed in two parts. The front plate 28 ″ in the table movement direction (FIG. 2) is kept a few tenths of a millimeter thinner and consists of softer material than the plate 28b behind it the following table rotation does not drag under plate 28 ". As a result of the different material hardness, the difference in thickness between the two plates does not change significantly even with continuous operation.

Die Anwendung dieses Gedankens beim Pressen einzelner, breiter Steine- besteht darin, die Dornführtingsplatte 28 (Fig. 3) in Tischdrehrichtung dünner werdend, also leicht koniscÜ auszubilden.The application of this idea when pressing individual, wide stones consists in making the mandrel guide plate 28 (FIG. 3) thinner in the direction of rotation of the table, that is to say slightly conical.
