Description
Prägepresse zum Herstellen von Stereotypie-Matrizen o. dgl. mit Kniehebeln zum Antrieb der Preßplatte Matrizenprägepressen sind bekannt, bei denen die Preßplatte durch Innen- oder Außenkniehebel angetrieben wird.Embossing press for producing stereotype matrices or the like with toggle levers Die stamping presses for driving the press plate are known in which the press plate is driven by inside or outside toggle levers.
Gemäß der Erfindung werden zwischen der Kraftquelle, beispielsweise einem Elektromotor, und der zum Bewegen der Kniehebel dienenden Kurbel unrunde Zahnscheiben vorgesehen, welche die Preßplatte im Augenblick des Höchstdruckes mit größter Übersetzung antreiben.According to the invention are between the power source, for example an electric motor, and the crank used to move the toggle levers non-round toothed disks provided which the press plate at the moment of maximum pressure with the greatest translation drive.
Durch die Erfindung wird es ermöglicht, entweder bei gleichbleibender Prägezeit den Prägedruck ganz erheblich zu erhöhen oder einen kleineren Motor zu verwenden.The invention makes it possible either with the same Embossing time to increase the embossing pressure quite considerably or to use a smaller motor use.
Auf der Zeichnung ist eine Prägepresse nach der Erfindung mit Innenkniehebel beispielsweise dargestellt, und zwar zeigen Abb. = eine Seitenansicht der Presse, und Abb. 2 einen teilweise geschnittenen Grundriß.The drawing shows an embossing press according to the invention with an internal toggle lever shown for example, namely Fig. = a side view of the press, and Fig. 2 is a partially sectioned plan.
Durch den Elektromotor a wird durch Vermittlung der ein- und ausschaltbaren Kupplung h, der Schnecke c, des Schneckenrades d und der Zahnräder e, f, g das große Zahnrad lz angetrieben, das auf der Welle i festgekeilt ist. Auf dieser sitzt auch ein verzahntes Ellipsenrad k, das ein zweites auf der Welle l sitzendes Ellipsenrad m. antreibt, das die Kniehebel n, o durch Vermittlung der Kurbel P und Pleuelstange q bewegt.By the electric motor a is switched on and off by mediating the Coupling h, worm c, worm wheel d and gears e, f, g the big one Gear lz driven, which is keyed onto the shaft i. Sitting on this too a toothed elliptical wheel k, which is a second elliptical wheel sitting on the shaft l m. that drives the toggle levers n, o through the intermediary of the crank P and connecting rod q moves.
Der untere Kniehebel o ist in Seitenstangen y gelagert, die den Preßkopf s tragen und ihn auf und ab bewegen.The lower toggle lever o is mounted in side bars y, which the press head s and move it up and down.
Die Ellipsenräder k, na machen die gleiche Anzahl Umdrehungen wie das Zahnrad lt, ändern aber während jeder Umdrehung ihr Übersetzungsverhältnis derart, daß sich der Preßkopf s in dem ersten leeren Teil seines Hubes schnell, allmählich aber langsamer bewegt. Im Augenblick des Höchstdruckes (Abb. x) steht der kleinste Radius des Ellipsenrades k gegenüber dem größten Radius des Ellipsenrades m, so daß der Preßkopf einen entsprechend erhöhten Druck ausübt.The elliptical gears k, na make the same number of revolutions as the gear lt, but change their transmission ratio during each revolution in such a way that the press head s moves quickly, gradually but more slowly, in the first empty part of its stroke. At the moment of maximum pressure (Fig. X), the smallest radius of the elliptical wheel k is opposite the largest radius of the elliptical wheel m, so that the press head exerts a correspondingly increased pressure.
