Description

Metallsträngpressen , werden.- -mit einer Vorrichtung ausgerüstet, die dazu dient, den unverpreßten Rest eines ausgepreßten Blockes von dem den Preßzylirnder abschließenden Matrizenhalt"-r" an dem -derselbe %fest"'haftet,'zn -lögen. An -dem. Preßrest seinerseits haftet meist .der Preßring, wshalb .die Trennvorrichtung mit einem Stößel versehen -wird,. mit dessen Hilfe der Preßring vom Preßrest abgestoßen wird. Die bauliche Gestaltung der bekannten. Vorrichtungen ist so, daß ein Schneidmesser an einem hydraulisch hin und -her bewegbaren Träger angeordnet ist, der .gleichzeitig Träger eines in geringem Abstand von dem Messer diesem vorgeordneten Stößels ist. -Die Arbeitskante des Stößels steht gegenüber der Messerschneide etwas vor, so daß der Stößel beim Vorwärtsbewegen des Messers- diesem -voreilend, vor Aufsetzen der Trennschneide den Preßring vom Preßrest abdrückt. Vorgenömüzeriwird dieser Arbeitsvorgang, nachdem der -Matrizenkopf. _ aus dem Preßzylinder entfernt und Preßrest mit Preßring freigelegt sind. _ -Bei besonders fest anhaftenden Preßresten-stößt der Trennvorgang auf Schwierigkeiten .dadurch, daß die Trennschneide des Messers besonders tief einschneideern - muß, bis der Preßrest sich ganzflächig vom Matrizenhalter löst. In diesem Falle zwängt sich der Preßrest zwischen. Trennmesser und Stößel. Das bringt unliebsame Betriebsstörungen, die zu vermeiden Zweck der Erfindung ist.Metal extrusion presses are equipped with a device which serves to remove the unpressed remainder of a pressed block from the press cylinder final die stop "-r" to which -the same% firmly "'adheres,' zn -logen. Press residue on its part mostly adheres to the press ring, which is why the separator also provided with a plunger ,. with the help of which the press ring is repelled from the press residue will. The structural design of the well-known. Devices is such that a cutting knife is arranged on a hydraulically movable back and forth, the .simultaneously Is a carrier of this upstream ram at a small distance from the knife. -The working edge of the ram protrudes slightly from the knife edge, so that the ram when moving the knife forward this-leading, before touching down the The cutting edge pushes the press ring off the press residue. This work process is carried out, after the die head. _ removed from the press cylinder and press residue with press ring are exposed. _ -When pressing residues are particularly firmly adhering, the separation process hits difficulties, because the cutting edge of the knife cuts particularly deep - Must, until the rest of the press releases from the die holder over its entire surface. In this case the press residue wedges itself between. Cutting knife and ram. That brings unpleasant ones Operational disruptions, which the purpose of the invention is to avoid.

Erfindungsgemäß wird vorgeschlagen, den Stößel ausweichbar anzuordnen. Das kann durch Anlenkung .desselben am Messerträger- geschehen, in welchem Falle es sich empfiehlt, die Druckberührung des Stößels mit dem Preßring zwischen- -die Abscherebene und die-Parallelebene durch den Gelenkzapfen zu legen. Dadurch wird ein Ausknicken des Stößels beim Aufsetzen auf den Preßring vermieden.According to the invention it is proposed to arrange the plunger in an evasive manner. This can be done by articulating the same on the knife carrier, in which case it is recommended that the pressure contact of the plunger with the press ring between -the Lay the shear plane and the parallel plane through the pivot pin. This will avoids buckling of the plunger when it is placed on the press ring.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

Mit i ist das Trennmesser und mit 2 der Stößel bezeichnet. Die zylindrische Druckfläche des Stößels ist mit 3 bezeichnet; -ihre Druckberührung liegt; wie .die Zeichnung zeigt, zwischen der Abscherebene und der durch die Gelenkachse 4 gehenden Parallelebene.-Trennmesser-und-Stößel sind an einem gemeinsamen Träger g angeordnet. Dieser ist an dem äußeren Ende des Kolbens 6 befestigt. Mit 7 ist der zugehörige Zylinder angedeutet.The separating knife is denoted by i and the plunger is denoted by 2. The cylindrical The pressure surface of the plunger is denoted by 3; - their pressure contact is; as the The drawing shows, between the shear plane and that passing through the joint axis 4 Parallel plane.-cutting-knife-and-ram are arranged on a common carrier g. This is attached to the outer end of the piston 6. With 7 is the associated Cylinder indicated.

Unterhalb der beschriebenen Vorrichtung ist der freigelegte Matrizenhalter 8 mit .dem hier anhaftenden Preßrest 9, und dem Preßring io dargestellt. Die Bereitschaftslage der genannten Teile ist derart, daß beim Niedergehen vom Messer i und Stößel 2 ersteres sich in der Trennebene i i und der Stößel sich auf den Preßring io aufsetzt. Dieser Vorgang vollzieht sich, wie schon oben gesagt, in zeitlicher Hintereinanderfolge so, daß nach Abstoßen des Preßrinzes io vom Preßrest g sich die Messerschneide in der Ebene i i aufsetzt und zwischen Preßrest und dem" Teil 8 eindringt. Dabei schiebt sich, falls der Preßrest besonders fest anhaftet, dieser zwischen Trennmesser und Stößel. Letzterer schwenkt dabei aus, ohne daß Störungen des Betr iebes zu befürchten sind.Below the device described is the exposed die holder 8 with .dem adhering press residue 9, and the press ring io shown. The preparedness of said parts is such that when going down from knife i and plunger 2 the former in the parting plane i i and the plunger sits down on the press ring io. This As already said above, the process takes place in chronological order so that after pushing off the press pin io from the press residue g the knife edge is in the level i i touches down and penetrates between the press residue and the "part 8. It pushes if the residue adheres particularly tightly, this between the cutting knife and Plunger. The latter swings out without fear of disruptions to operations are.
