Description

Unterstempel für umlaufende Formpressen. Bei den Pressen mit umlaufendem Formtisch und gleichmittig mitumlaufenden Ober-und Unterstempeln wird bei zylindrischer , Ausbildung des Preßlings dieser nach dem Preßvorgange aus der Matrize durch Hochtreiben des Unterstempels entfernt. Bei Ringpreßlingen bot die Entfernung bisher sehr große Schwierigkeiten dar. Der eben beschriebene Vorgang war durch den im Unter- i stenipel befindlichen Dorn nicht möglich.Lower punch for rotating compression molding. In the case of the presses with a rotating Forming table and co-rotating upper and lower punches is used in the case of cylindrical , Training of the compact this after the pressing process from the die by driving up of the lower stamp removed. In the case of ring moldings, the distance has hitherto been very great Difficulties. The process just described was caused by that in the lower stenipel located mandrel not possible.

Gegenstand der Erfindung ist ein Unter- .i steinpel, bei dem trotz Vorhandenseins des Dorns dennoch der Preßling aus der Matrize durch Hochstoßen des Unterstempels zu entfernen ist. Die Aufgabe ist dadurch gelöst, claß der Dorn mit dein Untersteinpelkörper nicht fest verbunden ist, sondern sich beweglich im Unterstempel befindet und mit dem Matrizenkörper gekuppelt ist. Hat die Pressung stattgefunden und soll der Preßling aus der Matrize entfernt werden, so wird der Unterstempel hochgetrieben. Hierbei wandert der Dorn nicht mit, sondern behält seine ursprüngliche Lage zur Matrize bei, während er sich anderseits in den Oberstempel hineinschiebt. Der Oberstempel ist zu diesem j Zweck mit einer den Dorn aufnehmenden Bohrung ausgestattet. Am Dorn sitzt ein Anschlag, zweckmäßig in Gestalt eines durchtretenden Stiftes. Dieser Stiftanschlag tritt beiderseits durch Schlitze des Unterstempelschaftes hindurch und wird durch eine kräftige Feder dauernd in Anlage mit dem Unterrande des Matrizenkörpers gehalten. An der Ausstoßstelle wandert der Stempel in die Matrize hinein, und es schiebt sich der Unterstempel über den Dorn und drückt die Feder zusammen. Der Anschlag des Dornes liegt an der Unterseite des Matrizenkörpers an.The subject of the invention is a lower .i steinpel, in which despite Presence of the mandrel still the compact from the die by pushing up the Lower stamp is to be removed. The task is solved by including the mandrel your lower body is not firmly connected, but is movable in the lower temple and is coupled to the die body. Has the pressing taken place and if the compact is to be removed from the die, the lower punch is driven up. The mandrel does not move with it, but retains its original one Position to the die, while on the other hand it pushes itself into the upper punch. For this purpose, the upper punch is equipped with a bore that receives the mandrel. A stop sits on the mandrel, expediently in the form of a penetrating pin. This pin stop passes through slots in the lower punch shaft on both sides and is permanently in contact with the lower edge of the die body by means of a strong spring held. At the ejection point, the punch moves into the die, and so does it the lower punch slides over the mandrel and compresses the spring. The attack of the mandrel rests on the underside of the die body.

Auf der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.

a ist der Unterstempel mit dem Kopfe b, der in a. befestigte Stempelhals. In ihm ruht der Dorn d, durch den als Anschlag eine Querstange f tritt. Gegen einen Bund des Dornes legt sich die starke Feder g und drückt den Dorn in seine richtige Stellung, die durch den Anschlag der Querstange am Körper der Matrize m bestimmt ist. Die Lage kann auch durch die Begrenzung der Seitenschlitze im Stempelhalse festgelegt sein.a is the lower stamp with the head b, which is in a. attached punch neck. The mandrel d rests in it, through which a cross bar f passes as a stop. Against a The strong spring g lies in the collar of the thorn and pushes the thorn into its correct position Position determined by the stop of the crossbar on the body of the die m is. The location can also be achieved by limiting the side slits in the punch neck be fixed.
