The ratio of the height the thickness of the half shells is 1-3: 1. Preferred Features: The half shells are identical. The alloy is AlMg4.5Mn. The wall thickness of the half shells is 3.0-3.5

Description

Die Erfindung betrifft eine Gasfläche, die aus zwei Gasflaschen- Halbschalen zusammengesetzt, die aus einer Aluminium- Legierung bestehen.The invention relates to a gas surface consisting of two gas cylinders. Half shells composed of an aluminum Alloy.

Die Gasfläche ist als Flüssiggaslager­ behälter oder Transportbehälter meist mit Propan, Butan oder deren Gemischen gefüllt. Das Gas wird beispielsweise als Brenngas im Küchenbereich, für Heizungen, für gewerbliche Zwecke etc. eingesetzt oder aber als Motorgas, um beispielsweise soge­ nannte Flurförderfahrzeuge wie Hubstapler anzutreiben.The gas area is used as a liquid gas storage facility Containers or transport containers mostly with propane, butane or their mixtures filled. The gas is, for example, as Fuel gas in the kitchen area, for heating, for commercial purposes etc. used or as engine gas, for example, so-called called industrial trucks such as forklifts.

Bisher bestehen Gasflaschen der betrachteten Art aus Stahl mit der Folge, daß sie ein beträchtliches Gewicht haben. Dies wirkt sich nachteilig beim Transport der Gasflaschen und bei deren Handhabung aus.So far, gas bottles of the type under consideration are made of steel the consequence that they have a considerable weight. This works disadvantageous in the transport of gas bottles and in their Handling off.

Der vorliegenden Erfindung liegt daher die Auf­ gabe zugrunde, eine Gasflasche anzugeben, die ein geringeres Gewicht hat und die dabei verhältnismäßig billig herstellbar ist.The present invention is therefore based on based on specifying a gas bottle that a smaller Has weight and which is relatively cheap to manufacture is.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Pa­ tentanspruchs 1 gelöst.This object is achieved by the features of Pa claim 1 solved.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unter­ ansprüchen gekennzeichnet. Advantageous embodiments of the invention are in the sub claims marked.  

Die erfindungsgemäße Gasflasche ist aus zwei Gasflaschen-Halb­ schalen zusammengesetzt, die miteinander verschweißt sind, wobei die Gasflaschen-Halbschalen aus einer Aluminium-Legierung beste­ hen, womit die Gasflasche erheblich leichter als eine Stahl­ flasche ist.The gas bottle according to the invention consists of two gas bottle halves shells assembled, which are welded together, whereby the gas bottle half shells made of an aluminum alloy hen, which makes the gas bottle considerably lighter than a steel bottle is.

Weiter ist vorgesehen, daß die Gasflaschen-Halbschalen aus einem Blech bzw. einer Ronde hergestellt sind, deren Wandstärke maxi­ mal 4 mm beträgt, was ebenfalls zu einer beträchtlichen Ge­ wichtsreduzierung der Gasflasche führt.It is also provided that the gas bottle half-shells from one Sheet or a round blank are made, the wall thickness maxi times 4 mm, which also leads to a considerable Ge weight reduction of the gas bottle leads.

Obwohl die Ronde damit im Hinblick auf die gesetzlichen Sicher­ heitsansprüche besonders dünn ist, werden die Gasflaschen-Halb­ schalen erfindungsgemäß ferner im Tiefziehverfahren in einem einzigen Arbeitsgang ohne Zwischenglühen hergestellt, wobei ferner erfindungsgemäß vorgesehen ist, daß das Verhältnis von Höhe zu Durchmesser der Halbschalen etwa 0,75 bis 1,3 beträgt. Dieser in einem einzigen Arbeitsgang erfolgende Tiefziehvorgang bringt es mit sich, daß die erfindungsgemäße Gasflasche verhält­ nismäßig kostengünstig herstellbar ist.Although the Ronde is so in terms of legal security is particularly thin, the gas cylinder will be half shell according to the invention also in the deep-drawing process in one single operation without intermediate annealing, being it is further provided according to the invention that the ratio of Height to diameter of the half-shells is about 0.75 to 1.3. This deep-drawing process takes place in a single operation entails that the gas bottle according to the invention behaves is reasonably inexpensive to manufacture.

Dies ist erst recht der Fall, wenn nach einem weiteren Vorschlag der Erfindung die zwei Gasflaschen-Halbschalen, aus denen die Gasflasche zusammengesetzt wird, eine identische Form haben, so daß nur ein einziges Ziehwerkzeug erforderlich ist.This is even more so when looking for another proposal the invention, the two gas bottle half-shells from which the Gas bottle is assembled to have an identical shape, so that only a single drawing tool is required.

In näheren Einzelheiten ist vorgesehen, daß die Gasflaschen- Halbschalen jeweils in einem ersten Stufenzug bis zu einer ersten Ziehtiefe, die bevorzugt etwa 50% der endgültigen Zieh­ tiefe beträgt, mit einem ersten Durchmesser gezogen werden, der größer als der endgültige Durchmesser der fertigen Halbschalen bzw. Gasflasche ist. In einem unmittelbar anschließenden zweiten Stufenzug werden dann die Halbschalen über die gesamte Ziehtiefe mit dem endgültigen Durchmesser gezogen. Die beiden Stufenzüge werden unmittelbar aufeinanderfolgend in dem Ziehwerkzeug ausge­ führt, ohne daß Zwischenprodukte aus dem Ziehwerkzeug entnommen werden müssen. Die Herstellung einer Gasflaschen-Halbschale dauert auf diese Weise nur etwa 15 Sekunden. Bei der herkömm­ lichen Herstellungsweise der Halbschalen sind hingegen folgende Schritte durchzuführen: Einfetten der Ronde, Einlegen in die Tiefziehpresse, Tiefziehen der ersten Stufe, Herausnehmen der ersten Stufe aus der Tiefziehpresse, Entfetten (als Vorbedingung für das anschließende Weichglühen), Transport zum Ofen, Weich­ glühen, Herausnehmen aus dem Ofen, Abkühlenlassen auf Raumtempe­ ratur, Wiedereinfetten, Einlegen in die Tiefziehpresse, Tiefzie­ hen der zweiten Stufe und eventuell einer dritten Stufe. Der Zeitbedarf bei zwei Stufen liegt beim Stand der Technik bei mindestens 12 Minuten.In more detail it is provided that the gas bottle Half shells each in a first tier up to one first draw depth, which is preferably about 50% of the final draw depth is drawn with a first diameter that larger than the final diameter of the finished half-shells or gas bottle. In a second immediately following The half-shells then become step-wise over the entire depth of the draw drawn with the final diameter. The two levels are successively made out in the drawing tool leads without intermediate products removed from the drawing tool  Need to become. The production of a gas bottle half-shell takes only about 15 seconds in this way. With the conventional However, the manufacturing method of the half-shells are as follows Steps to perform: grease the round blank, insert it into the Deep drawing press, deep drawing of the first stage, removal of the first stage from the deep drawing press, degreasing (as a prerequisite for the subsequent soft annealing), transport to the furnace, soft glow, take out of the oven, let cool to room temperature temperature, relubrication, insertion in the deep drawing press, deep drawing hen the second stage and possibly a third stage. The The time required for two stages is included in the prior art at least 12 minutes.

In einer bevorzugten Ausführungsform ist vorgesehen, daß die Wandstärke der Ziehbleche nur etwa 3,0 bis 3,5 mm beträgt, womit die erfindungsgemäße Gasflasche ein minimales Gewicht erhält. Dieses Gewicht beträgt nur etwa 5 kg, während eine herkömmliche Stahlflasche etwa 15 kg wiegt.In a preferred embodiment it is provided that the Wall thickness of the drawing plates is only about 3.0 to 3.5 mm, which means the gas bottle according to the invention receives a minimal weight. This weight is only about 5 kg, while a conventional one Steel bottle weighs about 15 kg.

In einer Ausführungsform der Gasflasche, die ein Fassungsver­ mögen von 11 kg Gas hat und deren Füllung bevorzugt als Brenngas verwendet wird, hat die Gasflasche eine Höhe von etwa 470 mm bei einem Durchmesser von etwa 300 mm. Derartige 11 kg-Gasflaschen sind in Stahlausführung weit verbreitet.In one embodiment of the gas bottle, the Fassungsver May have gas of 11 kg and their filling preferably as fuel gas is used, the gas bottle has a height of about 470 mm a diameter of about 300 mm. Such 11 kg gas bottles are widely used in steel.

Um die Wechsel- und Rüstzeiten insbesondere bei Flurförderfahr­ zeugen zu verkürzen, wäre es wünschenswert, wenn eine Flasche mit 14 kg Inhalt bereitgestellt würde, zumal nach den hiesigen Gesetzen erlaubt ist, bis zu 14 kg Gas in einer Flasche in geschlossenen Räumen zu lagern und zu verwenden. Aus diesem Grund wird vorgeschlagen, daß die erfindungsgemäße Gasflasche in einer Ausführungsform eine Höhe von etwa 560 mm hat bei einem Durchmesser von etwa 300 mm, womit diese Flasche ein Fassungs­ vermögen von 14 kg Flüssiggas hat und damit bestens für Motorgas geeignet ist. The changeover and set-up times, especially for industrial trucks to shorten witnesses, it would be desirable if a bottle would be provided with 14 kg content, especially according to the local ones It is allowed to put up to 14 kg of gas in a bottle in law store and use in enclosed spaces. For this Reason is proposed that the gas bottle according to the invention in one embodiment has a height of about 560 mm in one Diameter of about 300 mm, which makes this bottle a holder has a capacity of 14 kg LPG and is therefore ideal for engine gas suitable is.  

Als Aluminium-Legierung kann beispielsweise Al Mg 4,5 Mn ver­ wendet werden, ohne daß die Erfindung hierauf beschränkt ist.As the aluminum alloy, for example, Al Mg 4, 5 Mn ver be, turns without the invention being limited thereto.

Die Erfindung sieht demnach eine Gasflasche vor, die aus einem besonders dünnen Aluminiumblech im Tiefziehverfahren in einem einzigen Arbeitgang hergestellt ist. Das große Verhältnis von Höhe zu Durchmesser der Halbschalen in Höhe von etwa 0,75 bis 1,3 läßt sich im Tiefziehverfahren bisher allgemein nur dann erreichen, wenn die Wandstärke der Ronde deutlich oberhalb 6 bis 7 mm liegt. Überraschenderweise läßt sich das große Tiefziehver­ hältnis mit sehr viel niedrigerer Blechstärke erreichen, wenn in zwei aufeinanderfolgenden Stufenzügen zunächst eine erste Zieh­ tiefe mit einem größeren Durchmesser und in einem zweiten Stu­ fenzug die Halbschale über die gesamte Ziehtiefe auf den endgül­ tigen Durchmesser gezogen wird.The invention accordingly provides a gas bottle consisting of a particularly thin aluminum sheet in the deep-drawing process in one single operation is made. The large ratio of Height to diameter of the half-shells in the height of about 0.75 to So far, 1.3 can generally only be used in the deep-drawing process reach if the wall thickness of the round blank is clearly above 6 to 7 mm. Surprisingly, the large thermoformed achieve ratio with a much lower sheet thickness if in two consecutive level moves, first a first move deep with a larger diameter and in a second stu pull the half-shell over the entire depth of the draw onto the endgül term diameter is drawn.

Die Erfindung wird nachfolgend in näheren Einzelheiten mit Bezug auf die Zeichnung näher beschrieben. Dabei zeigen:The invention is described in more detail below with reference described in more detail on the drawing. Show:

Die in Fig. 1 dargestellte Gasflasche 1 besteht aus zwei Halb­ schalen 2, die eine identische Form haben und entlang einer mittigen Schweißnaht 3 zusammengesetzt sind. Die Gasflasche steht auf einem Fußring 4, der bevorzugt ebenfalls aus einer Aluminiumlegierung besteht und angeschweißt ist.The gas bottle 1 shown in Fig. 1 consists of two half-shells 2, which have an identical shape and are assembled along a central welding seam 3. The gas bottle stands on a foot ring 4 , which preferably also consists of an aluminum alloy and is welded on.

Im Zentrum des Kopfabschnitts der oberen Gasflaschen-Halbschale 2 sitzt eine Ventilmuffe 5, die bevorzugt eingeschweißt ist. Daneben sind Handgriffe 6 angeschweißt, die den Transport der Gasflasche erleichtern. In the center of the head section of the upper gas bottle half-shell 2 is a valve sleeve 5 , which is preferably welded in. In addition, handles 6 are welded on, which facilitate the transport of the gas bottle.

Die in Fig. 1 dargestellte Gasflasche hat eine Höhe von 472 mm bei einem Durchmesser von 300 mm und eine Wandstärke von 3,2 mm. Die Halbschalen 2 sind im Tiefziehverfahren in einem Arbeitsgang ohne Zwischenglühen hergestellt.The gas bottle shown in Fig. 1 has a height of 472 mm with a diameter of 300 mm and a wall thickness of 3.2 mm. The half-shells 2 are produced in a deep-drawing process in one operation without intermediate annealing.

Dies trifft auch für die Gasflasche gemäß Fig. 2 zu, die eine Höhe von 556 mm bei einem Durchmesser von 300 mm und einer Wandstärke von 3,5 mm hat. Bei dieser 14 kg-Gasflasche ist der Ventilbereich von einem Ventilschutzkragen 7 mit integrierten Handgriffen umgeben, der eine Beschädigung des Ventils bei der Handhabung der Flasche ausschließt.This also applies to the gas bottle according to FIG. 2, which has a height of 556 mm with a diameter of 300 mm and a wall thickness of 3.5 mm. In this 14 kg gas bottle, the valve area is surrounded by a protective valve collar 7 with integrated handles, which prevents damage to the valve when handling the bottle.
