Description

Vorrichtung zur Verriegelung von Schutztüren bei Pressen. Gegenstand der Erfindung ist eine Sicherheitsvorrichtung füt Pressen, inshesondere Exzenterpressen, mit auf und ab gehendem Preßstempel, bei welcher der Stempel durch aufklapphare Schntztüren abgeschlossen ist. Das Wesen der Erfindung besteht darin, daß die Schutztür durch einen Hebel und eine an der Tür angebrachte Nase gesichert oder freigegeben werden kann, dergestalt, daß der Verriegelungshebel nur bei stillgesetzter Presse aus der Sicherungsstellung gebracht werden kann, während die Bewegung des Einrückhebels in die Arbeitsstellung nur bei geschlossener und gesicherter Stellung der Tür vorgenommen werden kann.Device for locking protective doors on presses. object The invention is a safety device for presses, in particular eccentric presses, with up and down going press ram, in which the stamp by aufklapphare Protective doors is locked. The essence of the invention is that the protective door secured or released by a lever and a tab attached to the door can be, such that the locking lever only when the press is stopped can be brought out of the locking position while the movement of the engagement lever to the working position only when the door is closed and secured can be.

Auf der Zeichnung zeigt: Abb, i einen PressenantrieS in Vorderansicht, Abb. 2 einen Schnitt nach der Linie A-B der Abb. i. Die Presse wird von dem lose auf der Welle i laufenden'Schwungrad 2 angetrieben und bewegt in,nicht dargestellter Weise mittels Exzenter den Preßstempel, dessen Arbeitsfeld durch Schutztüren 3 gesichert werden soll. Die Türen 3 sind an dem Ständer 4 der Presse angelenkt. Das Schwungrad 2 kann mit der Welle i durch eine Kupplung 5 verbunden werden, die mittels der Gabel 6 und einer Zahnstange 7 bewegt werden kann. In die Zahnstange 7 greift ein Zahnsegnient 8 des Ausrückhebels 9 ein, der bei io am Maschinengestell 4 gelagert ist. Am Gestell 4 ist ferner ein Hebel i i bei 12 drehbar gelagert, der eine Nase 13 besitzt, die mit einem Vorsprung 14 an der SchutztÜr 3 zusammenwirken kann. Der Hebel i i besitzt ferner eine flache Vertiefung 15 und eine tiefere 16, die mit einem Zapfen 17 am Ausrückhebel 9 zusammenarbeitet.The drawing shows: Fig. I a front view of a press drive, Fig. 2 shows a section along the line AB in Fig. I. The press is driven by the flywheel 2 running loosely on the shaft i and moves the press ram, the working area of which is to be secured by protective doors 3, by means of an eccentric in a manner not shown. The doors 3 are hinged to the stand 4 of the press. The flywheel 2 can be connected to the shaft i by a coupling 5 which can be moved by means of the fork 6 and a rack 7 . A toothed segment 8 of the release lever 9 , which is mounted on the machine frame 4 at io, engages in the rack 7. On the frame 4, a lever ii is rotatably mounted at 12, which has a nose 13 which can interact with a projection 14 on the protective door 3 . The lever ii also has a shallow recess 15 and a deeper 16 which cooperates with a pin 17 on the release lever 9 .

Die Wirkungsweise der Vorrichtung ist folgende: In der Stellung gemäß Abb. i befindet sich die Nase 13 des Hebels i i gegenüber dem Vorsprung 14 der Tür 3, so daß diese nicht geöffnet werden kann. Der Zapfen 17 liegt in der flachen Vertiefung 15, so daß die Kupplung 5 sich in eingerückter Stellung befindet. Soll die Tür3 geöffnet werden, so muß zunächst die Kupplung 5 ausgerückt werden, was durch Linksbewegung des Ausrückhebels 9 geschieht. Damit kommt der Zapfen 17 gegenüber der Vertiefung 16 zu liegen, so daß sich der HeM ii über den Zapfen 17 senk-en kann. Hierdurch geht die Nase 13 nach oben und kommt aus dem Bereich der Stirnfläche des Vorsprunges 14, so daß die Schutztür 3 geöffnet werden kann. Ein Einrücken des Hebels 9 ist jetzt unmöglich, weil die Nase 13 oberhalb des Vorsprunges 14 liegt und der Hebel i i mittels der Vertiefung 16 den Ausrückhebel 9 festhält. Erst bei geschlossener Tür 3 kann der Hebel i i von dem Zapfen 17 abgehoben werden, um den Ausrückhebel 9 bewegen zu können. Es ist also der Ausrückhebel 9 mit dem Sicberungshebel i i derart gekuppelt, daß die Bewegung des einen Hebels von der des anderen abhängig ist.The mode of operation of the device is as follows: In the position according to Fig. I, the nose 1 3 of the lever ii is opposite the projection 14 of the door 3, so that it cannot be opened. The pin 17 lies in the shallow recess 1 5, so that the clutch 5 is in the engaged position. If the door 3 is to be opened, the clutch 5 must first be disengaged, which is done by moving the disengaging lever 9 to the left. The pin 17 thus comes to lie opposite the recess 16 so that the HeM ii can lower itself over the pin 17 . As a result, the nose 13 goes up and comes out of the area of the end face of the projection 14, so that the protective door 3 can be opened. Engagement of the lever 9 is j ow impossible, because the nose is located 13 above the projection 14 and the lever ii means of the recess 1 6 the release lever 9 holds. Only when the door is closed, the lever 3 can be lifted ii, to be able to move the release lever 9 of the pin 1. 7 The release lever 9 is thus coupled to the safety lever ii in such a way that the movement of one lever is dependent on that of the other.
