  Vorrichtung zum   Niederführen   unterer Pressstempel, insbesondere bei Pressen mit umlaufendem
Formtisch und Ober-und Unterstempeln. 



   Die Unterstempel bei Pressen mit umlaufendem Formtisch werden durch Hubschienen zurückgezogen, die einseitig am Stempelkopf angreifen. Dieser einseitige, also ausserhalb 
 EMI1.1 
 schiene. 



   Gegenstand der Erfindung ist eine Einrichtung,   diesem Übelstand   abzuhelfen und doch die Stempel sicher aus der   Pressstellung zurückzuführen.   Es wird jeder Stempel s, wie die Zeichnung erkennen lässt, mit einer Pufferfeder f versehen und zwischen Feder f und Kopf   k.   erhält er noch eine etwas vorstehende Scheibe b. Sobald der Stempel die Pressstelle verlassen hat, wirkt die Feder f und drückt ihn   zurück.   Sollte die Feder erschlaffen und nicht vollständig den Stempel zurückführen, so läuft schliesslich die Scheibe b an eine ganz kurze Schiene n an und führt den Stempel vollständig zurück. Die Schiene n liegt kurz vor der   Füllstelle.   



   Die bisher notwendigen, verhältnismässig langen und daher schwer auswechselbaren Schienen sind dadurch vermieden. Die Hauptrückführarbeit wird durch die Federn f bewirkt und die Führung   li   in Verbindung mit der Scheibe b auf dem Stempel s stellt eine Sicherungseinrichtung dar.

  Device for lowering the lower ram, especially in presses with rotating
Form table and upper and lower punches.



   The lower punches in presses with a revolving forming table are pulled back by lifting rails that grip the punch head on one side. This one-sided, i.e. outside
 EMI1.1
 rail.



   The subject of the invention is a device to remedy this inconvenience and yet safely return the stamp from the pressing position. As the drawing shows, each punch s is provided with a buffer spring f and between spring f and head k. he receives a slightly protruding disc b. As soon as the punch has left the press point, the spring f acts and pushes it back. If the spring slackens and does not completely return the punch, the disk b finally runs against a very short rail n and guides the punch back completely. The rail n is just before the filling point.



   The previously necessary, relatively long and therefore difficult to replace rails are thereby avoided. The main return work is effected by the springs f and the guide li in connection with the disk b on the punch s represents a safety device.
