Abstract

The flexible tube blank is made as a hydraulic hose, which is slid onto a flexible mandrel of heat-resistant material. This assembly is then laid into a mold and vulcanized. Preferred features: The hydraulic flexible hose complete, comprises an inner layer (1) and outer layer (2) of elastomeric material, with a reinforcing inlay (3) of braided steel wire, The blank is made as a hydraulic hose and pre-vulcanized. It is slid onto a flexible mandrel of heat-resistant material. This is then placed in a mold and vulcanization is completed. A flexible mandrel of thermally-resistant plastic is used.

Description

Schläuche aus elastomerem Werkstoff mit geflochtenen Stahldrahteinlagen für den Einsatz bei hydraulisch betriebenen Anlagen und Aggregaten aller Art, in der Maschinenindustrie, für Gabelstapler, Erdbewegungsmaschinen, Hebebühnen, Bagger und landwirtschaftliche Maschinen sind bekannt.Hoses made of elastomeric material with braided steel wire inserts for the Use in hydraulically operated systems and aggregates of all kinds, in the Machine industry, for forklift trucks, earth moving machines, lifting platforms, excavators and agricultural machines are known.

Derartige Hydraulikschläuche zum Durchleiten von Hydrauliköl auf Mineralölbasis, Öl- und Wasseremulsionen sowie wäßrigen Glykollösungen zeichnen sich durch eine Temperaturbeständigkeit von -40°C bis +100°C (kurzzeitig +125°C) aus. Die Innenschicht (Seele) und Außenschicht (Decke) besteht dabei insbesondere aus synthetischen Kautschukqualitäten, wobei die Decke darüber hinaus besonders abriebfest und witterungsbeständig ist. Der Festigkeitsträger ist ein Geflecht aus vergüteten, oberflächengeschützten Stahldrähten.Such hydraulic hoses for passing hydraulic oil based on mineral oil, oil and water emulsions and aqueous glycol solutions are characterized by a Temperature resistance from -40 ° C to + 100 ° C (briefly + 125 ° C). The The inner layer (soul) and outer layer (ceiling) consist in particular of synthetic rubber qualities, with the ceiling also special is resistant to abrasion and weather. The reinforcement is made of a braid tempered, surface-protected steel wires.

Die Rollenlänge der Hydraulikschläuche beträgt üblicherweise 3 m bis 150 m.The roll length of the hydraulic hoses is usually 3 m to 150 m.

Die Erfindung betrifft nun die Verwendung des oben umrissenen Schlauches als Hydraulik-Formschlauch für den Einsatz im Hochdruckbereich. Der Formschlauch kann dabei ein Krümmerschlauch (DE 199 12 304 C1) oder eine Formschlauchverzweigung (DE 34 03 727 C2) sein.The invention now relates to the use of the hose outlined above as Hydraulic molded hose for use in high pressure areas. The molded hose can a manifold hose (DE 199 12 304 C1) or a molded hose branch (DE 34 03 727 C2).

Ein weiterer Teil der Erfindung besteht darin, ein Verfahren zum Herstellen eines Hydraulik-Formschlauches bereitzustellen.Another part of the invention is a method of making a To provide hydraulic molded hose.

Die erfindungsgemäßen Verfahrensschritte sind:
The process steps according to the invention are:

  • - Herstellen des Schlauchrohlings als Hydraulikschlauch; - Manufacture of the hose blank as a hydraulic hose;  
  • - Aufschieben des Schlauchrohlings auf einen flexiblen Dorn aus hitzebeständigem Werkstoff;- Pushing the tube blank onto a flexible mandrel made of heat-resistant Material;
  • - Einlegen des aufgedornten Schlauchrohlings in eine Form; sowie- Insert the thorned tube blank into a mold; such as
  • - Vulkanisation in der Form.- Vulcanization in the mold.

Nach einer besonders vorteilhaften Verfahrensvariante erfolgt unmittelbar nach dem Herstellen des Schlauchrohlings eine Vorvulkanisation, verbunden mit einer abschließenden Endvulkanisation in der Form.According to a particularly advantageous variant of the method takes place immediately after Manufacture of the tube blank a pre-vulcanization, connected with a final vulcanization in the mold.

Weiterhin ist es zweckmäßig, wenn ein flexibler Dorn aus hitzebeständigem Kunststoff eingesetzt wird.Furthermore, it is useful if a flexible mandrel made of heat-resistant plastic is used.

Im Zusammenhang mit dem Dornwerkstoff muß erwähnt werden, daß sich ein Hydraulik-Formschlauch nicht oder nur sehr schwer auf Metalldornen herstellen läßt.In connection with the mandrel material it must be mentioned that a Hydraulic molded hose can not or only very difficult to manufacture on metal mandrels.

In Verbindung mit einer schematischen Zeichnung wird nun ein Hydraulik- Formschlauch in der Gattung eines Krümmerschlauches vorgestellt.In conjunction with a schematic drawing, a hydraulic Shaped hose presented in the genus of a manifold hose.

Der Krümmerschlauch umfaßt eine Innenschicht 1 und eine Außenschicht 2 aus elastomerem Werkstoff, d. h. aus Gummi oder gummiähnlichem Werkstoff. Eingebettet ist eine einzige Einlage 3 aus geflochtenem Stahldraht als Festigkeitsträger. Auch eine mehrlagige Festigkeitsträgervariante ist möglich.The elbow hose comprises an inner layer 1 and an outer layer 2 made of elastomeric material, ie of rubber or rubber-like material. A single insert 3 made of braided steel wire is embedded as a strength member. A multi-layer strength member variant is also possible.
