Description
Es sind nach ,dem Reibun@gsprinztip arbeitende Grubenstempel bekannt, welche die hohen S@chloßkräfte in ,der Weise herabsetzen, daß .eine Vieleahl von Dnuclc bzw. Zug übertrageivden (Lamellen) neberneinandergeschaltet und durch die gleiche Schloßkraft belastet wird. Bei allen diiesen Stempeln sind idie langen Lamellen :im bzw. am Innenstempel befestigt, bzw. der Innenstempel wird durch diese gebildet (Drucklamellen). Diese Anordnung der Lamellen hat große Nachteile. Die Lamellen liegen frei und sind d eer Verschmutzung ausgesetzt, oder aber die Einschübmöglichkeit des Stempels ist stark reduziert. Das sich am Stempeil befindende Schloß ist beim Bruchbau besonders hinderlich. Das Auswechselnder Lamellen :ist umständlich, da der Stempel vollständig dem onttert werden muß.Pit punches working according to the friction principle are known, which minimize the high locking forces in such a way that a variety of Dnuclc or train transferring (lamellas) connected side by side and through the same lock force is loaded. All of these stamps have the long lamellae : fixed in or on the inner punch, or the inner punch is formed by this (Pressure lamellas). This arrangement of the lamellae has major disadvantages. The slats are exposed and exposed to soiling, or the insertion option of the stamp is greatly reduced. The lock on the stamp is at Fractional construction particularly obstructive. Replacing the slats: is cumbersome, there the stamp must be completely onttert.
Alle diese Nachteile vermeidet die vorliegende Erfindung. Sie besteht darin, daß die ,langen Lamellen nunmehr im bzw. am Außenstempel. angeordnet sind und ein: am unteren Ende des Innen, stempels ibefindli:ohes Paket von" kurzen Zwiscben-bzw. Drucklamellen an den langen Lamellen entlang gleitet. Der die Lamellen zusammenpres!s#ende Druck wird durch einen am Kopf des Stempels angeordneten, an sich bekannten Mechanismus geregelt.The present invention avoids all of these disadvantages. she consists in that the long lamellae are now in or on the outer die. are arranged and a: at the lower end of the inside, stamp ibefindli: ohes package of "short interim or. Pressure slats slide along the long slats. Which presses the slats together Pressure is applied by a known mechanism located at the head of the stamp regulated.
Zwei Aus.fühnungsbeispiele zeigen die Z-eichnungen.The drawings show two examples.
D:ie Eig. i und 2 ,stellen einen Stempel mit' geteiltem Innenstempel i und 2 dar. Die zusätzliche Innenversippung 3 dient einmal zur Erhöhung dLs Widerstandsmoments und zum anderen zur Aufnahme der Kurzlamellen 4. -Die Platte 5 hält die beiden Stempelteile zusammen und bfldiet gleichzeitig die Auflage bzw, den Drehpunkt für das durdh dem Mechanismus im Kopf des Irinenstempiels durch Vermittlung des Gestänges 6 und 7 zu betätigende Druckelement, z. B. einen Exzenter B. Die langen Lamellen 9 sind um' den Steg io herumgelegt, der seinerseits am Außenstempel ii befestigt ist. Eine zweite Ausfüb;nungsform zeigen die Fig. 3 und 4. Der Innenstempel wird duirch ein Doppel-T-Profil 12 gebildet, welches ebenfalls am unteren Endre die Kurzlamellen 13 trägt. An Konsolen 14 des Außenstempels hängen die langen Lamellen 15. Der Reibungsdruck wird durch einen vom Mechanismus .im Stempelkopf mittels eines Gestänges 16 zu betätigenden Keil 17 erzeugt. Die langen Lamel'len können auch als druckbelastete Körper ausgebildet sein. Sie können auch auf ihrer ganzen Länge am Außenstempel befestigt oder ganz oder teilweise durch eine Innenverrippung dies Außenstempels ersetzt werden.T: he prop. i and 2, represent a stamp with 'split inner stamp i and 2. The additional internal bracing 3 serves once to increase the drag torque and on the other hand to accommodate the short lamellae 4. - The plate 5 holds the two stamp parts together and bfldiet at the same time the support or , the fulcrum for the durdh the mechanism in the head of the Irinenstemspiels by mediation of the linkage 6 and 7 to be actuated pressure element, z. B. an eccentric B. The long lamellae 9 are placed around 'the web io, which in turn is attached to the outer die ii. A second embodiment is shown in FIGS. 3 and 4. The inner punch is formed by a double-T profile 12, which also carries the short lamellae 13 at the lower end. The long lamellae 15 hang on brackets 14 of the outer punch. The frictional pressure is generated by a wedge 17 to be actuated by the mechanism in the punch head by means of a rod 16. The long lamellae can also be designed as a pressure-loaded body. They can also be attached to the outer die over their entire length or replaced in whole or in part by internal ribbing on the outer die.
