Description

Bez. : "Wärmebehandlungsvorriohtung Die Erfindung betrifft eine Wärmebehandlungsvorrichtung zum Verfestigen von mittels duroplastischer Kleber hergestellten Verbindungen.Ref.: "Heat treatment device The invention relates to a heat treatment device to consolidate connections made with thermoset adhesives.

Duroplastische Kleber benötigen für die Verfestigung der dar mit hergestellten Klebeverbindungen normalerweise eine Ausl härtungszeit von ca. 24 Stunden. Zur AbkUrzung der Aushärtungsdauer ist es allgemein bekannt die Klebstelle einer W§rmehehandlung auszusetzen. Dazu werden die Elemente nach dem Klebevorgang in eine aufheizbare Kammer eingebracht, in der der Kleber bereits nach ca. 30 Min. ausgehärtet und die Klebeverbindung verfestigt ist.Thermoset adhesives need to solidify the dar with manufactured Adhesive joints normally have a curing time of approx. 24 hours. For short the curing time, it is generally known the glue point of a heating dealership suspend. To do this, the elements after the Gluing process into a Heatable chamber introduced in which the adhesive cures after approx. 30 minutes and the adhesive bond is solidified.

In einer aufheizbaren Kammer können aber nur Klebeverbin dungen verfestigt werden, wenn die Abmessungen der zu verklebenden Elemente insgesamt die Innenabmessungen der Kammer un terschreiten. Zur Beschleunigung der Aushärtung einer mittels duroplastischer Kleber hergestellten Rohrleitungsverbindung scheidet daher eine beheizbare Kammer herkömmlicher Bauart aus. Es ist aber besonders an Baustellen nachteilig, wenn von Rohrleitungsstück zu Rohrleitungsstück die unter normalen Temperaturen erforderlichen Aushärtungszeiten abgewartet wer den müssen. Vor der Beendigung des Aushärtungsprozesses führen nämlich bereits geringfügige Relativbewegungen der zu ver bindenden Teile zu einer undichten oder aber festigkeitsmäßig geschwächten Verbindung.In a heatable chamber, however, only adhesive connections can be solidified when the dimensions of the elements to be glued together match the internal dimensions fall below the chamber. To accelerate the hardening of a thermosetting plastic Pipe connection made with glue therefore separates a heatable chamber conventional design. However, it is particularly disadvantageous on construction sites if from Pipe section to pipe section the required under normal temperatures You have to wait for the curing times. Before the end of the curing process namely lead already slight relative movements of the parts to be connected to ver to a leaky or weakened connection.

Die Erfindung hat sich die Aufgabe gestellt, eine Wärmebehand lungsvorriohtung zum Verfestigen von n'ittels duroplastischer Kleber hergestellten Verbindungen zu schaffen, die insbesondere unabhängig von der Länge der einzelnen miteinander mit verbindenden Elemente einsetzbar ist, So soll die Wärmebehandlungsvorrichtung vorfzugsweise für die Verlegung von Rohrleitungen auf der Baustelle und für Anschlüsse an bereits verlegten Rohrlertungen dienlich sein.The invention has the task of providing a heat treatment device to solidify connections produced by means of thermosetting adhesives create that particular regardless of the length of each with each other connecting elements can be used, so the heat treatment device should preferably for laying pipelines on the construction site and for connections to already laid pipelines are useful.

Zur Lösung der gestellten Aufgabe schlägt die Erfindung als Wärmebehandlungsvorrichtung eine aufheizbare Manschette vor, die die miteinander zu verbindenden Elemente im Bereich der Klebetelle mit Abstand umschließt, Unabhängig von den Längsabmessungen der einzelnen Elemente bestimmt allein der freie Querschnitt der Manschette die Verwendbarkeit der erfindungsgemäßen Wärmebehandlungsvorrichtung, wobei ein verhältnismäßig geringer Abstand zwischen der Innenfläche der Manschette und der Außenfläche der einzelnen Elemente ausreicht, um eine gleichmäßige Wärmebehandlung des Klebstellenbereichs zu erzielen.To solve the problem, the invention proposes a heat treatment device a heatable sleeve that holds the elements to be joined together in the Surrounds the area of the bonding point at a distance, regardless of the longitudinal dimensions of the individual elements is determined solely by the free cross-section of the sleeve Usability of the heat treatment device according to the invention, with a relatively small distance between the inner surface of the cuff and the outer surface of the individual elements is sufficient for a uniform heat treatment of the adhesive area to achieve.

Damit die Heizwirkung der Manschette sich ohne nennenswerten Verlust auf den jeweiligen Klebstellenbereich konzentrieren kann, weist die Manschette gemäß einem weiteren Vorschlag der Erfindung zu beiden Seiten Je einen geteilten auswechselbaren, dem Außenumfang der miteinander zu verklebenden Elemente angepaßten Abdeckflansch auf.So that the heating effect of the cuff increases without any significant loss can concentrate on the respective adhesive area, the sleeve according to another proposal of the invention on both sides each with a shared interchangeable, the outer circumference of the elements to be glued together adapted cover flange on.

Durch diese erfindungsgemäße Ausbildung ist die Möglichkeit geschaffen, ein und dieselbe Wärmebehandlungsvorrichtung bei.-spielsweise für Rohrleitungen von 25 mm bis 150 mm Nennweite zu verwenden, wobei lediglich entsprechende Abdeckflansche auszuwählen sind.This inventive training creates the possibility of one and the same heat treatment device for example for pipelines from 25 mm to 150 mm nominal width to be used, whereby only appropriate cover flanges are to be selected.

Zum leichten Austausch der Abdeckflansche schlägt die Brfindung vor, daß die geteilten Flansche in die Manschette hineinreichende Vorsprünge aufweisen, die zwischen federbelasteten Kugelpaaren, welche an der Innenseite der Manschette gehalten sind, eingeklemmt werden.For easy replacement of the cover flanges, the finding suggests that the split flanges have protrusions reaching into the sleeve, between the spring-loaded pairs of balls, which are on the inside of the sleeve are held in place.

Es liegt natürlich im Rahmen der Erfindung, auch andere leicht lösbare Befestigungsmittel für die Abdeckflansche als Schnellverschlüsse auszubilden.It is of course within the scope of the invention to include other easily detachable ones Train fasteners for the cover flanges as quick-release fasteners.

Die Aufheizung des von der Manschette und den Abdeckflanschen eingeschlossenen Raumes erfolgt nach einem weiteren Vorschlag der Erfindung mittels über die Innenseite der Manschette in gleichmäßigem Abstand verteilt angeordneter Heizstäbe, denen die elektrische Energie über Kabel zugeführt wird, die in besonders vorteilhafter Weise durch einen auf der Außenseite der Manschette befestigten hohl ausgebildeten Handgriff verlegt sind.The heating of the enclosed by the cuff and the cover flanges According to a further proposal of the invention, the space is carried out by means of the inside the cuff evenly spaced arranged heating rods, which the electrical energy is supplied via cable, which is particularly advantageous by a hollow handle attached to the outside of the cuff are relocated.

Schließlich schlägt die Erfindung noch vor, daß vom freien Endteil des Handgriffs ein Stecker umschlossen wird, der mit einem die Energiezufuhr intermittierend steuernden Vorschaltgerät verbindbar ist. Das Vorschaltgerät hat die Wirkung, daß es die Wärmebehandlungsvorrichtung mit ihrer Nennleistung abwechselnd ein- und ausschaltet. So läßt sich mit einem derartigen Gerät beispielsweise durch ein beheiztes Bimetallelement die Energiezufuhr so steuern, daß bei entsprechender Einstellung bestimmte Wärmebehandlungstemperaturen, die z. B. für Epoxidharz maximal 1400 C und für Vinylesterharz maximal 900 C betragen dürfen, nicht überschritten werden.Finally, the invention also proposes that the free end part of the handle, a plug is enclosed, which intermittently supplies the energy with one controlling ballast is connectable. The ballast has the effect that it switches the heat treatment device on and off alternately with its rated power. So can be with such a Device for example by a heated bimetal element control the energy supply so that with the appropriate setting certain heat treatment temperatures, e.g. B. for epoxy resin a maximum of 1400 C and for vinyl ester resin may not exceed 900 C.
