Abstract
Description
Die Erfindung betrifft eine Schweißheizung für das Herstellen von Kunststoffrohrmatten, wobei die Kunststoffrohrmatten aus einer Anzahl parallel angeordneter flexibler Kunststoffrohre bestehen, welche stoffschlüssig durch Schweißen mit einem Sammelrohr verbunden sind.The invention relates to a welding heater for the production of plastic pipe mats, the plastic pipe mats made of a number of parallel flexible Plastic pipes are made, which are cohesive by welding with a manifold are connected.
Zur Zeit werden Schweißheizungen eingesetzt, die aus einem Grundkörper bestehen. Dieser Grundkörper ist in einer Maschine angeordnet und wird durch Heizpatronen auf die benötigte Temperatur gebracht. An diesem Grundkörper sind beidseitig Schweißspiegel angeordnet, die die spezielle Form für das Erwärmen der Kunststoffteile besitzen. Es werden mit diesem Grundkörper auf der einen Seite Kunststoffteile erwärmt, die eine kleine Masse besitzen, während auf der anderen Seite die Kunststoffteile eine große Masse besitzen.Welding heaters are currently used which consist of a basic body. This Base body is arranged in a machine and is heated to the required level by heating cartridges Brought temperature. Welding mirrors are arranged on both sides of this base body have the special shape for heating the plastic parts. It will be with this Base body heated on one side plastic parts that have a small mass, while on the other hand, the plastic parts have a large mass.
Diese Ausführung der Schweißheizung hat den Nachteil, daß nur eine Temperatur zur Verfügung steht. Die flexiblen Kunststoffrohre haben aber einen ganz anderen Masseanteil wie das Sammelrohr. Die Wahl der Anheiztemperatur ist sehr schwierig und die Temperaturtoleranz muß kleingehalten werden, damit beim Anheizen die flexiblen Kunststoffrohre eine Temperatur einnehmen, die zum Verschweißen nicht zum Verbrennen der flexiblen Kunststoffrohre führt, und auch das Sammelrohr die benötigte Schweißtemperatur besitzt. Raumumgebungsbedingungen, wie Zugluft, Luftfeuchtigkeit und Raumtemperatur können sich schon nachteilig auf den Anheizprozeß auswirken. Es kann zu Verbrennungen bzw. zu nicht genügender Erwärmung der flexiblen Kunststoffrohre bzw. des Sammelrohres kommen. In beiden Fällen wird ein ungenügendes Schweißergebnis erreicht.This version of the welding heater has the disadvantage that only one temperature Available. The flexible plastic pipes, however, have a completely different mass proportion such as the manifold. The choice of the heating temperature is very difficult and that Temperature tolerance must be kept low so that the flexible Plastic pipes have a temperature that is not suitable for welding and not for burning the flexible plastic pipes leads, and also the header pipe the required welding temperature owns. Room environment conditions such as drafts, air humidity and room temperature can adversely affect the heating process. It can cause burns or insufficient heating of the flexible plastic pipes or the collecting pipe come. In both cases, an insufficient welding result is achieved.
Die Verbrennung des flexiblen Kunststoffrohres kann man vermeiden, wenn man flexibles Kunststoffrohr und Sammelrohr zeitlich unterschiedlich anheizt. Hierbei muß man allerdings mit Produktivitätsverlusten rechnen. Außerdem muß der Zeitunterschied neu eingeregelt werden, wenn man anderen Kunststoff mit einem anderen Temperaturverhalten einsetzt.The burning of the flexible plastic pipe can be avoided if you have flexible Plastic pipe and manifold heated differently in time. Here you have to expect productivity losses. In addition, the time difference must be adjusted if you use different plastic with a different temperature behavior.
Der Erfindung liegt die Aufgabe zugrunde, eine Schweißheizung für unterschiedliche Materialdicken auszuführen, bei der eine Verbrennung bzw. ungenügende Erwärmung der flexiblen Kunststoffrohre und des Sammelrohres vermieden wird, die Raumumgebungsbedingungen keinen Einfluß auf das Anheizen haben, und zeitlich keine Verluste bei der Herstellung von Kunststoffrohrmatten auftreten.The invention has for its object a welding heater for different Execute material thicknesses in which a combustion or insufficient heating of the flexible plastic pipes and the manifold is avoided Ambient conditions have no influence on the heating up, and no time Losses occur in the manufacture of plastic pipe mats.
Die Aufgabe wird erfindungsgemäß dadurch gelöst,According to the invention, the object is achieved by
- - daß auf einer Grundplatte zwei Basiskörper gleicher oder unterschiedlicher Ausführung parallel und mit Abstand zu einander angeordnet sind,- That on a base plate two base body of the same or different design are arranged in parallel and at a distance from each other
- - daß in der lösbaren Teilebene eines Basiskörpers ein oder mehrere Heizelemente längs zum Heizspiegel angeordnet sind, daß in einem anderen Basiskörper die Heizelemente nacheinander im rechten Winkel zum Heizspiegel angeordnet sind.- That in the detachable part of a base body one or more heating elements lengthways to Heating mirrors are arranged that the heating elements in another base body are successively arranged at right angles to the heating mirror.
Vorteilhaft wurde gelöst, daß die Basiskörper symmetrisch ausgeführt sind.It was advantageously solved that the base bodies are designed symmetrically.
In der Teilebene des erstgenannten Basiskörpers wird zu den vorhandenen Heizelementen ein zu- und abschaltbares Heizelement angeordnet. Es kann hiermit bei hohen Matrerialdicken eine bessere Energieanpassung vorgenommen werden.In the sub-level of the first-mentioned base body, an existing heating element is added heating element can be switched on and off. This can result in a high material thickness better energy adjustment can be made.
Die Basiskörper können aus Aluminium bzw. aus Invarstahl ausgebildet werden. Zwischen den Basiskörpern kann vorteilhaft Isolationsmaterial angeordnet sein.The base body can be made of aluminum or invar steel. Insulation material can advantageously be arranged between the base bodies.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch die Gestaltung der Basiskörper und deren bedarfsgerechten Anordnung eine zielgerichtete Aufheizung der zu verschweißenden Teile vorgenommen werden kann. Außerdem sind schädliche Raumumgebungsbedingungen ausgeschlossen und es können kürzeste Fertigungszeiten ohne Schädigungen des Kunststoffes erzielt werden, wobei Temperaturen und Aufheizzeiten von den zuverschweißenden Teilen spezifisch abgestimmt werden können.The advantages achieved by the invention are, in particular, that the design the base body and its needs-based arrangement a targeted heating of the welding parts can be made. They are also harmful Ambient conditions are excluded and shortest manufacturing times can be achieved without Damage to the plastic can be achieved, with temperatures and heating times of the parts to be welded can be specifically matched.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und im folgenden näher beschrieben. Die Zeichnung zeigt die schematische Darstellung der erfindungsgemäßen Schweißheizung, wobei ein Basiskörper mit Teilebene dargestellt ist und der andere Basiskörper keine Teilebene besitzt.An embodiment is shown in the drawing and described in more detail below. The drawing shows the schematic representation of the welding heater according to the invention, one base body is shown with a sub-plane and the other base body is not a sub-plane owns.
Auf der Grundplatte 1 ist der Isolierstoff 2 angeordnet, auf dem wiederum die beiden Basiskörper 3 und 4 parallel und mit Abstand angeordnet sind. Der Basiskörper 3 ist mit einer lösbaren Teilebene 8 dargestellt. Die Teilebene 8 wird benötigt, damit die Heizelemente 5 und 11, welche über die ganze Länge vom Basiskörper 3 reichen, angeordnet und bei Ausfall gewechselt werden können. Der Heizkörper 11 ist angeordnet, um bei großen Materialdicken zugeschaltet zu werden. Es steht somit die benötigte Energie zum Vorschweißen des Kunststoffes bei großen Materialdicken zur Verfügung. Der Basiskörper 4 ist, im Gegensatz zum Basiskörper 3, mit vielen Heizelementen 9 ausgestattet. Diese sind durch Bohrungen in der Basisplatte 1 und dem Isolierstoff 2 bis in den Basiskörper 4 durchgeführt und im rechten Winkel zum Heizspiegel 10 nacheinander angeordnet. Auch hier können, wie bei der vorhergehenden Lösung, einzelne Heizelemente 9 zum Vorschweißen von großen Kunststoffmaterialausbildungen geschaltet werden. Eine Schweißheizung kann mit zwei Basiskörper 3, mit zwei Basiskörpern 4, oder mit je einem Basiskörper 3 und 4 ausgerüstet sein.On the base plate 1 , the insulating material 2 is arranged, on which in turn the two base bodies 3 and 4 are arranged in parallel and at a distance. The base body 3 is shown with a detachable partial plane 8 . The sub-level 8 is required so that the heating elements 5 and 11 , which extend over the entire length of the base body 3 , can be arranged and replaced in the event of failure. The heater 11 is arranged to be switched on with large material thicknesses. The energy required to weld the plastic with large material thicknesses is thus available. In contrast to the base body 3 , the base body 4 is equipped with many heating elements 9 . These are carried out through bores in the base plate 1 and the insulating material 2 into the base body 4 and arranged one after the other at right angles to the heating mirror 10 . Here too, as in the previous solution, individual heating elements 9 can be switched to pre-weld large plastic material constructions. A welding heater can be equipped with two base bodies 3 , with two base bodies 4 , or with one base body 3 and 4 each.
Die Basiskörper 3, 4 besitzen Flächen 6 zur Aufnahme der Schweißspiegel 7 und 10. Die Schweißspiegel 7 und 10 sind in ihrer Form an die Schweißaufgabe angepaßt. Die Fläche 6 ist so gestaltet, daß bei einer Wärmedehnung der Basiskörper 3, 4 eine axiale Verschiebung der Schweißspiegel 7, 10 möglich ist. Die Anpassung ist nötig, wenn bei Wechsel der Kunststoffart die Verschweißtemperatur geändert werden muß, und dadurch zwangsläufig andere Ausdehnungen der Basiskörper 3, 4 auftreten.The base bodies 3 , 4 have surfaces 6 for receiving the welding mirrors 7 and 10 . The shape of the welding mirrors 7 and 10 is adapted to the welding task. The surface 6 is designed so that the thermal expansion of the base body 3 , 4, an axial displacement of the welding mirror 7 , 10 is possible. The adjustment is necessary if, when changing the type of plastic, the welding temperature has to be changed, and as a result other dimensions of the base body 3 , 4 necessarily occur.
Damit die Energie der Heizelemente 5, 9 und 11 schnell an die Schweißspiegel 7 und 10 transportiert werden kann, ist es sinnvoll, wenn die Basiskörper 3, 4 in Aluminium ausgeführt sind.So that the energy of the heating elements 5 , 9 and 11 can be quickly transported to the welding mirrors 7 and 10 , it is useful if the base bodies 3 , 4 are made of aluminum.
Es kann allerdings auch sinnvoll sein, vor allem dann, wenn durch Materialwechsel die Temperaturen ständig angepaßt werden müssen, die Grundplatte 1 und die Basiskörper 3, 4 aus Invarstahl auszubilden. Der Invarstahl besitzt einen Ausdehnungskoeffizienten, der nur 10% vom Wert des Ausdehnungskoeffizienten von Stahl entspricht. Bei Temperaturänderungen treten dann nur noch vernachlässigbare Verschiebungen auf.However, it can also be useful, especially if the temperatures have to be constantly adjusted by changing the material, to form the base plate 1 and the base body 3 , 4 from Invar steel. The Invar steel has an expansion coefficient that corresponds to only 10% of the value of the expansion coefficient of steel. With temperature changes, only negligible shifts then occur.
In der Zeichnung nicht dargestellt ist eine Lösung, bei der die beiden Basiskörper 3, 4 auf der Gegenseite der Grundplatte 1 miteinander verbunden sind. Diese Lösung hat den Vorteil, daß die Basiskörper 3, 4 in ihrer relativen Position zueinander fixiert sind, und durch die Reaktionskräfte beim Schweißen nicht verschoben werden.A solution is not shown in the drawing, in which the two base bodies 3 , 4 are connected to one another on the opposite side of the base plate 1 . This solution has the advantage that the base bodies 3 , 4 are fixed in their relative position to one another and are not displaced by the reaction forces during welding.
Zur Temperaturanpassung an die Schweißaufgabe besitzen die Basiskörper 3, 4 bei bestimmten Arbeitsaufgaben unterschiedliche Temperaturen. Es kann dabei von Vorteil sein, wenn Isolationsmaterial zwischen beiden Basiskörpern 3, 4 angeordnet wird, damit durch Strahlung die niedrige Temperatur eines Basiskörpers nicht verfälscht wird.In order to adapt the temperature to the welding task, the base bodies 3 , 4 have different temperatures for certain work tasks. It can be advantageous here if insulation material is arranged between the two base bodies 3 , 4 , so that the low temperature of a base body is not falsified by radiation.
