Abstract

The cable has a uniform external cross section and a specially shaped internal cross section in which an inner chamber mould is centered in the tool and can be intermittently disengaged out of its holder into the press matrix thus intermittently moulding a tubular body whilst forcing the necessary gas volume through the inner chamber mould and when disengaged moulding a solid section. Pref. the necessary wires for the cable are intermittently passed through the internal chamber mould.

Description

Titel: Strangpreß-Blasverfahren für elastisches Kabel Anwendungsgebiet: Die Erfindung betrifft ein Verfahren ur kontinuierlichen Herstellung von unendlich langen Preßteilen ii gleichbleibendem Außenquerschnitt und speziell gestaltetem, veränderlichen Irnienquerschnitt, besonders zur IIerstellung von elastischem Kabel nach Patentanmeldung 20 30 309.7 für nichtmetallische elastische Werkstoffe im Strangpreß-Blasverfahren.Title: Extrusion-blow molding process for elastic cables Area of application: The invention relates to a method for continuous production of infinity long pressed parts ii constant external cross-section and specially designed, variable irnial cross-section, especially for the creation of elastic cables according to patent application 20 30 309.7 for non-metallic elastic materials in the extrusion-blow molding process.

Zweck: Bei der Herstellung von elastischem Kabel ist es erforderlich, in einem Strangpreßteil mit gleichbleibendem Außenquerschnitt Innenkammern mit einem bemessenen Luftvolumen und Kammerwände anzubringen sowie Litze diskontinuierlich einzuführen.Purpose: In the manufacture of elastic cable, it is necessary to in an extruded part with a constant outer cross-section inner chambers with a measured air volume and chamber walls to be attached as well as discontinuous stranded wire to introduce.

Stand der Technik: Es ist bekannt, daß in einem Strangpreßverfahren nur Profile mit gleichbleibendem Innenquerschnit t und bei Blasverfahren nur einzelne EIohlkörper hergestellt werden können.Prior art: It is known that in an extrusion process only profiles with a constant internal cross-section and only individual ones in the case of blow molding processes Egg hollow bodies can be produced.

Kritik des Standers der Technik: Eine kontinuierliche Herstellung von kombinierten Blas- und Strangpreßteilen ist bisher nicht möglich.Prior Art Criticism: Continuous Manufacturing of combined blown and extruded parts is so far not possible.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, durch Kombination eines Stranpreßverfahrens mit einem Blasverfahren die erstellung von elastischem Kabel zu ermöglichen.Task: The invention is based on the task of combining an extrusion process with a blow molding process the creation of elastic cable to enable.

Lösung: Diese Aufgabe wird dadurch gelöst, daß in ein Strangpreßwerkzeug eine ausrückbare Innenkammerform zentriert in die Preßmater eingebracht wird und dazu dient, bei zeitweiligem Einrücken derselben einen Schlauchmantel zu pressen, Litze und Luft zuzuführen und beim Ausrücken die Innenkammern des elastischen Kabels zu verschließen.Solution: This object is achieved in that in an extrusion die a disengageable inner chamber mold is introduced centered in the press material and serves to press a hose jacket when the same is temporarily indented, Supplying braid and air and, when disengaging, the inner chambers of the elastic cable to close.

Weitere Ausgestaltung: Zur Steuerung des Ein- und Ausrückens der Innenkammerform sowie zur ReguLierung der Litzen- und Luftzufuhr sind Kontaktgeber vorgesehen.Further configuration: To control the engagement and disengagement of the inner chamber shape as well as for regulating the strand and air supply, contactors are provided.

Erzielbare Vorteile: Die it der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß mit der Kombination eines Strangpreßverfahrens mit einem Blasverfahren die Herstellung von elastischem Kabel mit unterschiedlichem Innenquerschnitt, der durch Kammern und Kammerwände zur Aufnahme und fixierung dcr eingebrachten Litze entsteht, ermöglicht wird.Achievable Advantages: The advantages that can be achieved by the invention exist in particular that with the combination of an extrusion process with one Blow molding the production of elastic cables with different internal cross-sections, the braid inserted through chambers and chamber walls for receiving and fixing the wire arises, is made possible.

Beschreibung eines Ausführungsbeispiels: Ein Ausführungsbeispiels der Erfindung sowie die verschiedenen Verfahrensstufen sind in den Zeichnungen (i'i'ur 1-f) näher beschrieben.Description of an exemplary embodiment: An exemplary embodiment of the invention and the various process stages are shown in the drawings (i'i'ur 1-f) described in more detail.

Figur 1 zeigt das Strangspreß-Blasverfahren beim Herstellungsbeg tl. 1 Kammer. Die Innenkammerform (4) ist durch die Halterung (3) zentriert in die gekühlte Preßmater (1) eingeführt und wird durch das Führungsstück (#) gehalten. Dadurch ist das zwangsläufige Pressen des erhitzten und unter Druck stehenden Mantelwerkstoffs (2) in Schlauchform möglich, wobei mit gleicher Geschwindigkeit wie die Preßgeschwindigkeit durch die Bohrung (5) Litze und durch die Bohrungen (6) das notwendige Luftvolumen zugeführt wird, was durch die geöffneten Kontakte (7 und 8) gesteuert wird. Figure 1 shows the extrusion blow molding process at the start of production tl. 1 chamber. The inner chamber shape (4) is centered in the holder (3) cooled press material (1) and is inserted through the guide piece (#) held. This results in the inevitable pressing of the heated and pressurized jacket material (2) possible in tubular form, with the same speed as the pressing speed through the hole (5) strand and through the holes (6) the necessary air volume is supplied, which is controlled by the open contacts (7 and 8).

Figur 2 zeigt den Zustand der Verfahrensstufe aus Figur 1 in dem Moment, in dem durch Kotaktgabe bei Kontakt (7) die Litzenzufuhr durch die Bohrung (5) kurzfristig stark erhöht wird.FIG. 2 shows the state of the process stage from FIG. 1 at the moment in which by making contact with contact (7) the litz wire feed through the hole (5) for a short time is greatly increased.

Figur 3 zeigt den Zustand nach Abschluß der erhöhten Litzenzufuhr unter gleichzeitigem eiterpressen und gleichbleibender Litzenzufuhr.FIG. 3 shows the state after completion of the increased strand supply with simultaneous pus pressing and constant strand feed.

Figur 4 zeigt die Verfahrensstufe, in der durch Kontakt abe bei KKontakt (8) die Innenkammerform in der Halterung (3) belegt, d.h. ausgerückt, und die Luftzufuhr gestoppt wurde, um durch Freigabe der Preßmater und durch Kohäsionskräfte des Preßwerkstoffes das Verschliecken der Kammern zu erreichen.Figure 4 shows the process stage in which by contact abe at KContact (8) the inner chamber shape in the holder (3) occupied, i.e. disengaged, and the air supply was stopped by releasing the press material and by cohesive forces of the press material to achieve the sealing of the chambers.

@ Fort ang des Verfahrens wird durch Öffnen des Kontaktes (#) die Innenkammerform wieder ein eruckt und die Luftzufuhr freigegeben, womit die in Figur 1 dargestellte Verfahrensstufe wieder #rreicht ist. @ Continuing the procedure, opening the contact (#) opens the Inner chamber shape again jerks and the air supply is released, bringing the in figure 1 is reached again.
