Description
Sicherheitseinrichtung am Vorschubgetriebe von selbsttätigen Pressen u. dgl. An den bekannten selbsttätigen Exzenterpressen, Stanzen, Lochmaschinen u. dgl. wird vielfach der Vorschub des Preßgutes oder des Werkstückes durch einen starren zweiarmigen Hebel a (Ab-h. i) bewirkt, dessen einer Arm meistens gabelartig und mit Rollen versehen zwangläufig in einer schrägen. Ringnut der Antriebswelle geführt wird, während sein anderer Arm die Schubstange b bei jeder Umdrehung der Hauptwelle- bewegt. Sobald aber der Vorschubmechanismus festhakt, klemmt oder sonst in seiner Bewegung gehindert wird, muß eine Beschädigung der Maschine oder des Vorschu.bliebels a eintreten.Safety device on the feed gear of automatic presses On the known automatic eccentric presses, punches, punching machines and the like. Like. Often the feed of the material to be pressed or the workpiece through a rigid one two-armed lever a (Ab-h. i) causes, one arm of which is mostly fork-like and provided with rollers inevitably in a sloping position. Annular groove of the drive shaft out while his other arm pushes the push rod b with every revolution of the main shaft emotional. But as soon as the feed mechanism gets stuck, jams or otherwise in his If movement is prevented, the machine or the feed must be damaged a enter.
Die vorliegende Erfindung soll diese Beschädigungen verhindern und besteht darin, daß der den Vorschub vermittelnde, zwang-ZD I 'äuf ig von der Hauptwelle angetriebene Hebel a nach Abb. i in einen zweiarmigen Hebel c und einen einarmigen Hebel d nach Abb. 2 unterteilt ist. Der einarmige Hebel d ist mit dem freien Ende des zweiarmigen Hebels c lösbar durch eine federnde Pfannenkupplung e verbunden, so daß die Haltekraft der Kupplung durch Spannen der Kupplungsfeder f geregelt werden kann. Wird jetzt durch Festklemmen des Vorschubmechanismus der Vorschubhebel überlastet, so schnappt die Pfannenkupplung e aus, ohne daß eine Beschädigung des Getriebes eintritt.The present invention is intended to prevent this damage and consists in the fact that the forced ZD I ', which mediates the feed, is frequently operated by the main shaft driven lever a according to Fig. i into a two-armed lever c and a one-armed lever Lever d is divided according to Fig. 2. The one-armed lever d is with the free end of the two-armed lever c releasably connected by a resilient socket coupling e, so that the holding force of the clutch can be regulated by tensioning the clutch spring f can. If the feed lever is now overloaded by clamping the feed mechanism, so the socket coupling e snaps out without damaging the transmission entry.
Da die Hauptwelle weiterläuft, würde jetzt, wo das Werkstück usw. vorzeitig stehengeblieben, ist, eine Betriebsstörung eintreten können. Dies wird dadurch vermieden, daß bei Eintritt der Relativbewegung beider Hebel zueinander elektrische Kontakte g, gl betätigt werden, die ein Stillsetzen des Antriebs in bekannter Weise bewirken.Since the main shaft continues to run, now where the workpiece etc. stopped prematurely, an operational disruption can occur. this will thereby avoided that when the relative movement of the two levers occurs to one another electrical contacts g, gl are actuated, which stop the drive in cause in a known way.
