Description
Luftpuffer für den Karren von Zweitouren-Schnellpressen Die Erfindung betrifft einen Luftpuffer für den Karren von Zweitouren-Schnellpressen, bei denen die schädlichen Luftpufferräume durch Verstellen eines Gegenkolbens vergrößert oder verkleinert werden. Diese Vergrößerung oder Verkleinerung der schädlichen Räume ist zum Einstellen des Druckes bei den verschiedenen Geschwindigkeiten der Schnellpresse notwendig. Bei einer bekannten Vorrichtung dieser Art kann je ein Kolben nur für sich allein verstellt werden. Dies ist, da ja mindestens an jedem Hubende -in, oft aber auch zwei Luftpuffer vorhanden sind, nicht mir umständlich, sondern auch eine Quelle für Fehler, da die Kolben versehentlich verschieden weit verstellt werden können.Air buffer for the cart of two-turn high-speed presses The invention relates to an air buffer for the cart of two-turn high-speed presses in which the damaging air buffer spaces are enlarged or by adjusting an opposing piston can be reduced in size. This enlargement or reduction of the harmful spaces is for adjusting the pressure at the various speeds of the high-speed press necessary. In a known device of this type, a piston can only be used for be pretended to be alone. This is often because at least at each end of the stroke But there are also two air buffers, not cumbersome for me, but also one Source of error, as the pistons are accidentally moved differently can.
Diese Nachteile werden gemäß der Erfindung dadurch beseitigt, daß die an beiden Hubenden der Schnellpresse angeordneten Gegenkolben auf einer mit Rechts- und Linksgewinde versehenen gemeinsamen Spindel angeordnet sind. Durch Drehen dieser Spindel wird infolgedessen ein gemeinsames und gleichmäßiges Verstellen der Kompressionsräume an beiden Hubenden bewirkt. Die Verdrehung der Spindel ist dabei über einer Skala ablesbar.These disadvantages are eliminated according to the invention in that the opposed pistons arranged at both ends of the stroke of the high-speed press on one with Right-hand and left-hand threaded common spindle are arranged. Go berserk this spindle is consequently a common and uniform adjustment of the Causes compression spaces at both ends of the stroke. The rotation of the spindle is included readable from a scale.
Ein Ausführungsbeispiel der Eifindung ist auf der Zeichnung schematisch dargestellt. An jedem Ende des Karrens i sitzen ein oder zwei Kolben 2, die: in entsprechenden Luftpufferzylindern 3 arbeiten und dort abgebremst werden. Die schädlichen Räume der Luftpufferzylinder sind über eine Rohrleitung 4 mit einem Zylinder 5 verbunden. In den Zylindern 5 ist ein Gegenkolben 6 angeordnet, der durch eine Spindel? verschoben werden kann. Diese hat Rechts- und Linksgewinde und ist bei 8 drehbar, aber axial unverschiebbar gelagert. Durch Drehen des Handrades 9 werden beide Kolben 6 gemeinsam und gleichmäßig verstellt. Über eine Schnecke to und ein Schneckenrad i i wird ein Zeiger i z auf der Skala 13 eingestellt, von der die Größe der Kompressionsräume jederzeit abgelesen werden kann. Um beim Zusammenbau der Maschine die Größe der K.ompressionsräume an den beiden Hubenden einregeln zu können, ist in der Spinde17 eine Flanschverbindung 1,4 vorgesehen.An embodiment of the invention is shown schematically in the drawing shown. At each end of the cart i there are one or two pistons 2 which: in corresponding air buffer cylinders 3 work and are braked there. The harmful ones Rooms of the air buffer cylinders are connected to a cylinder 5 via a pipe 4. A counter-piston 6 is arranged in the cylinders 5, which is driven by a spindle? postponed can be. This has right-hand and left-hand threads and is rotatable at 8, but axially immovably mounted. By turning the handwheel 9, both pistons 6 become common and adjusted evenly. Via a worm to and a worm wheel i i becomes a Pointer i z set on the scale 13, of which the size of the compression spaces can be read at any time. To change the size of the To be able to regulate compression spaces at both ends of the stroke is in the locker17 a flange connection 1.4 is provided.
