Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf den Antrieb der für das Anheben des unteren beweglichen Werkzeuges an zweischneidigen hydraulischen Pressen oder Scheren erforderlichen Gegenkolben. Sie besteht darin, daß der zum Anheben dieser Kolben erforderliche Druck durch die Preßwirkung der Presse selbst erzeugt wird.The invention relates to the drive for the lifting of the lower movable Tool on double-edged hydraulic presses or scissors. It consists in the pressure required to lift these pistons through the pressing action of the press itself is produced.
Die hierzu erforderliche Einrichtung derThe necessary setup of the
ίο Presse ist auf der beiliegenden Zeichnung durch einen Vertikalschnitt dargestellt. An den oberen Preßkopf e sind zwei Kolben u und ν angeschlossen. Diese tauchen in zwei an dem festen Gestell α der Presse vorgesehene Zylinder und verdrängen beim Vorgehen des Preßkopfes unter entsprechendem Druck Wasser. Dieses Wasser wird durch die gezeichneten besonderen Leitungen unter die Kolben s und t der im festen Untergestell angeordneten Gegenzylinder geführt und bringt dadurch das Anheben der Traverse g mit dem unteren Werkzeug h hervor. Da die Wirkung der Kolben u ν sofort mit dem Vorgehen des mit dem Werkzeug/ versehenen oberen beweglichen Pressenteiles de beginnt, so folgt daraus, daß auch gleichzeitig der Anhub des unteren beweglichen Pressenteiles eingeleitet wird und mithin gleichzeitige Bewegung beider Pressenteile unbedingt stattfindet. Die Bewegung des oberen Pressenteiles erfolgt in bekannter Weise entweder durch den Übersetzer b η oder durch Zuleitung von Druckwasser durch zum Zylinder c. Der Rückzug erfolgt durch die Zylinder i k. ίο The press is shown in the accompanying drawing by means of a vertical section. Two pistons u and ν are connected to the upper press head e. These plunge into two cylinders provided on the fixed frame α of the press and, when the press head moves, displace water under appropriate pressure. This water is led through the special lines drawn under the pistons s and t of the counter-cylinder arranged in the fixed underframe and thereby brings about the lifting of the cross member g with the lower tool h . Since the action of the piston u ν begins immediately with the action of the upper movable press part de equipped with the tool /, it follows that the lift of the lower movable press part is initiated at the same time and consequently simultaneous movement of both press parts takes place. The upper part of the press is moved in a known manner either by the booster b η or by supplying pressurized water through to the cylinder c. The retraction takes place through the cylinder i k.
Die beschriebene Anordnung gestattet mancherlei konstruktive Abänderungen, ohne daß der Grundgedanke gleichzeitiger Bewegung beider Pressenteile eine Abänderung erfährt.The arrangement described allows various structural changes without that the basic idea of simultaneous movement of both press parts is a change learns.
