The press cylinders are each couplable to the slidable cross-piece by a coupling including a coupling rod and a stationary clamping jaw and a pressable clamping jaw cooperating with the coupling rod, the pressable clamping jaw being activated by at least one single acting hydraulic cylinder.

Description

Die Neuerung bezieht sich auf eine hydraulische Presse zum Verpressen von mit Glasfasern verstärkten Kunststoffmatten zu Formteilen, mit einer festen und einer verschiebbaren Pressentraverse sowie einem Pressenantrieb, bei der zum Antrieb der verschiebbaren Pressentraverse mindestens ein Verstellzylinder mit einer dem Arbeitshub der Presse entsprechenden Hublänge und mindestens zwei an die verschiebbare Pressentraverse ankuppelbare Preßzylinder kurzen Hubs angeordnet sind, wobei jeder Preßzylinder über eine Kupplung an die verschiebbare Pressentraverse kuppelbar ist.The innovation relates to a hydraulic press for pressing plastic mats reinforced with glass fibers into molded parts, with a fixed and a displaceable press crossmember and a press drive in which at least one adjusting cylinder with a stroke length corresponding to the working stroke of the press and at least two is used to drive the displaceable press crossmember short-stroke press cylinders that can be coupled to the displaceable press crossmember are arranged, each press cylinder being able to be coupled to the displaceable press crossmember via a coupling.

Zwei Pressen der vorgenannten Art sind in-der DE-Patentanmeldung P 33 23 931. 2 beschrieben-und dargestellt.Two presses of the aforementioned type are described and shown in DE patent application P 33 23 931.2.

Zur Erzeugung des Preßhubs sind bei beiden Pressen je vier Preßzylinder eingesetzt, von denen jeder über eine Formschlußkupplung an die verschiebbare Pressentraverse kuppelbar ist.To generate the press stroke, four press cylinders are used in each of the two presses, each of which can be coupled to the displaceable press crossmember via a form-fitting coupling.

Alle Formschlußkupplungen der ersten Presse enthalten je eine Gewindestange, alle der zweiten je eine Stange mit unterbrochenem Vielkeilprofil.All form-locking couplings of the first press each contain a threaded rod, all of the second one a rod with an interrupted multi-spline profile.

Derartige Formschlußkupplungen erlauben das Kuppeln der Preßzylinder an die verschiebbare Pressentraverse in jeder Teilungsebene des Gewindes bzw. des unterbrochenen Vielkeilprofils.Such form-locking couplings allow the coupling of the press cylinder to the displaceable press crossmember in each division plane of the thread or the interrupted multi-spline profile.

Der Abstand zweier benachbarter Teilungsebenen eines eingängigen Gewindes entspricht der Gewindesteigung. Beim unterbrochenen Vielkeilprofil ist der Abstand zweier benachbarter Teilungsebenen das Maß von Unterbrechnung zu Unterbrechung.The distance between two adjacent parting planes of a single-start thread corresponds to the thread pitch. In the case of an interrupted multi-wedge profile, the distance between two adjacent division levels is the measure of interruption to interruption.

Diesen Pressenkonstruktionen haftet der Nachteil an, daß der kurze Hub der Preßzylinder in dem gesamten Arbeitshubbereich der Presse nicht immer voll als Preßhub genutzt werden kann.These press designs have the disadvantage that the short stroke of the press cylinders cannot always be used fully as a press stroke in the entire working stroke area of the press.

Der Preßhubverlust ist in dem gesamten Arbeitshubbereich einer jeden Presse durchschnittlich die Hälfte des Abstandes zweier benachbarter Teilungsebenen.The loss of the press stroke in the entire working stroke area of each press is on average half the distance between two adjacent dividing planes.

Der Neuerung liegt die Aufgabe zugrunde, eine Presse der eingangs genannten Art so auszubilden, daß der Hub der Preßzylinder in dem gesamten Arbeitshubbereich der Presse voll als Preßhub genutzt werden kann.The innovation is based on the task of designing a press of the type mentioned in such a way that the stroke of the press cylinder can be fully used as a press stroke in the entire working stroke area of the press.

Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß zum Kuppeln eines jeden Preßzylinders an die verschiebbare Pressentraverse eine Kupplungsstange, mindestens eine fest: und mindestens eine andrückbare Spannbacke angeordnet sind.According to the invention, this object is achieved in that a coupling rod, at least one fixed: and at least one press-on clamping jaw are arranged for coupling each press cylinder to the displaceable press crossmember.

Zweckmäßigerweise sind jeweils zwischen zwei andrückbaren Spannbacken zweier Kupplungsstangen mehrere Spannzylinder übereinander angeordnet.Expediently, a plurality of clamping cylinders are arranged one above the other between two press-on clamping jaws of two coupling rods.

Die Spannzylinder sind mit je einem einfachwirkenden Kolben ausgeführt.The clamping cylinders are each designed with a single-acting piston.

Jede andrückbare Spannbacke ist quer zur Preßhubrichtung bewegbar angeordnet.Each pressable clamping jaw is movably arranged transversely to the direction of the press stroke.

Bei Übertragung großer Preßkräfte auf die verschiebbare Pressentraverse erhält jede Kupplungsstange mindestens einen Längsschlitz, wobei jedem Längsschlitz mindestens eine Spannplatte zugeordnet ist.When large pressing forces are transmitted to the displaceable press crossmember, each coupling rod is provided with at least one longitudinal slot, with at least one clamping plate being assigned to each longitudinal slot.

Jede Spannplatte ist quer zur Preßhubrichtung bewegbar angeordnet.Each clamping plate is movably arranged transversely to the direction of the press stroke.
