Heizmanschette für Kunststoff-FormlingeHeating jacket for plastic moldings

Kunststoff-Formlinge neigen zu Spannungskorrösionsrissen. Es ist bekannt, daß solche Formlinge verschweißt werden können. Bei solchen geschweißten Formlingen treten auch an der Stelle der Schweißnaht Spannungskorrosionsrisse auf. Dies ist bei allen bekannten Schweißmethoden der Fall, sei es bei Direktschweißung wie Spiegelschweißung, sei es bei Draht«- oder Pul verschweißung. Hierbei ist auch beobachtet worden, daß Brüche im Gebiet der Schweißstelle durch Spannungen im Schweißgut und Versprödungen des Schweiß« lings vorkommen. Diese Versprödungen und Spannungen kommen daher, daß in einem sehr eng begrenzten Bereich das zu schweißende Gut starken Temperaturwechseln unterworfen wird.Plastic moldings are prone to stress corrosion cracks. It is known, that such moldings can be welded. With such welded Moldings also show stress corrosion cracks at the point of the weld seam on. This is the case with all known welding methods, be it with Direct welding such as mirror welding, be it wire or powder welding. It has also been observed that fractures in the area of the Welding point due to tension in the weld metal and embrittlement of the sweat " lings occur. These embrittlement and tension are due to the fact that in In a very narrowly limited area, the material to be welded changes in temperature is subjected.

Um derartige Fehler zu unterbinden ist es günstig, den notwendigen Temperaturweehsel auf einer größeren Länge des Sehweißstüeks so vorzunehmen, daß ein nur langsam ansteigender Temperaturgradient zur Schweißstelle hin vorhanden ist und daß das Schweißgut auch nur langsam wieder abgekühlt wird.In order to prevent such errors, it is beneficial to take the necessary temperature change on a larger length of the Sehweißstüeks so that a there is only a slowly increasing temperature gradient towards the welding point and that the weld metal is also only slowly cooled down again.

Eine Vorrichtung, die dies ermöglicht,, und dies ist der Inhalt der vorliegenden Erfindung, wird im folgenden besehrieben:A device that makes this possible, and this is the content of the present Invention is described below:

Es handelt sich hierbei um eine Vorrichtung zum Anwärmen von Kunststoff-Formlingen zum Verschweißen, dadurch gekennzeichnet, daß sie aus einer Heizmanschette mit Abschlußstücken (1) besteht, die so ausgebildet sind, daß sieThis is a device for heating plastic moldings for welding, characterized in that it consists of a heating jacket with terminators (1) which are designed so that they

auf dem Formling einen Temperaturgradienten erzeugen, der am jeweils zu verschweißenden Ende der Formlinge (4) sein Maximum erreicht.Generate a temperature gradient on the molding that corresponds to the one to be welded The end of the moldings (4) has reached its maximum.

Diese Manschette besteht, wie aus Zeichnung I hervorgeht, aus zwei Abschlußstücken (1), in die die zu schweißenden Profile eingesetzt werden. Die Abschlußstüeke haben eine, von innen nach außen verlaufende Abschrägung (2), die nicht/oder schwächer beheizt ist als die Hittelstücke der Manschette (3)· Dadurch entsteht beim Aufheizen ein Temperaturgradient, der nur die Profilenden (4) stark aufheizt und so Spannungen verlaufend anbaut. Beim Schweißen selbst wird die Manschette abgeklappt oder anderweitig entfernt und die Profilenden können nun mit einer der üblichen Schweißtechniken miteinander-verschweißt werden. Gleichzeitig kann die Manschette, um Oxydationen des jeweiligen Kunststoffs bei der Aufwärmung zu verhindern, mit einem Inertgas-Einlaß (5) versehen sein, durch den ein Schutzgas in die Manschette gepresst wird.As can be seen from drawing I, this cuff consists of two end pieces (1) into which the profiles to be welded are inserted. The final pieces have a bevel (2) running from the inside to the outside, which is not / or less heated than the middle sections of the cuff (3) a temperature gradient is created during heating that affects only the profile ends (4) heats up strongly and thus builds up tensions. When welding itself the cuff is folded down or otherwise removed and the profile ends can now be welded together using one of the usual welding techniques will. At the same time, the sleeve can be provided with an inert gas inlet (5) in order to prevent oxidation of the respective plastic when it is heated through which a protective gas is pressed into the cuff.

Eine andere beanspruchte Ausbildungsform'derselben Heizmanschette ist in Zeichnun II dargestellt. Hier sind die Abschlußstücke (1) nicht verlaufend, sondern im Verhältnis zur beheizten Mantelfläche (3) sehr viel kurzer gehalten, so daß sich auch hier ein Temperaturgradient auf den zu schweißenden Profilstücken aufbaut.Another claimed form of the same heating jacket is shown in the drawing II shown. Here the terminators (1) are not running, but kept much shorter in relation to the heated jacket surface (3), so that Here, too, there is a temperature gradient on the profile pieces to be welded builds up.

Zeichnung III zeigt eine weitere beanspruchte Ausbildungsform derselben Manschette, die hier in der Mitte einen beheizten Schweißspiegel (6) trägt, so daß hier die Schweißmanschette beim Sehweißvorgang nicht entfernt zu werden braucht. Es wird hier zum Durchschweißen lediglich der beheizte Schweißspiegel (6), an dem die Profilenden (4) für kurze Zeit angelegt sind, durch Herausziehen durch den Schlitz (7) entfernt. Diese Form hat den Vorteil, daß die verschweißten Profilenden (4), wenn dies aus Materialgründen gewünscht wird, auch langsam abgekühlt werden können, indem man die Schweißmanschette nicht entfernt, Dieser Abkühlungsvorgang kann noch verlangsamt werden. Man kann über einen Regelwiderstand und einen Hegeltransformator die Mantelheizung langsam zurückstellen. Drawing III shows a further claimed embodiment of the same cuff, which here in the middle carries a heated welding mirror (6), see above that here the welding cuff cannot be removed during the welding process needs. Only the heated welding mirror is used here for welding through (6), on which the profile ends (4) are placed for a short time, removed by pulling them out through the slot (7). This shape has the advantage that the welded Profile ends (4), if this is desired for material reasons, too can be cooled slowly by not removing the welding cuff, This cooling process can be slowed down. You can use a rheostat and a Hegel transformer slowly turn back the jacket heating.

In Zeichnung IV ist eine weitere beanspruchte Form der Heizmanschette gezeigt, die sich besonders für dickwandige Hohlprofile eignet. Hier wird durch eine Innenheizung (8) von innen zusätzlich die Wand erwärmt* In diesem Fall müssen vor der Schweißung die Hohlprofile aus der Heizmanschette herausgezogen werden.In drawing IV, another claimed form of the heating jacket is shown, which is particularly suitable for thick-walled hollow profiles. Here is through an interior heater (8) also heats the wall from the inside * In this case the hollow profiles must be pulled out of the heating jacket before welding.

Zeichnung T zeigt eine weitere beanspruchte Form,, bei der für dickwandige Hohlprofile die innere Beheizung (8) konisch ausgebildet ist, damit sieh im Rohrinnern ein Temperaturgradient noch besser verlaufend aufbaut. Auch die Außenheizung (3) ist hier konisch ausgebildet, um den Temperaturgradientenverlauf zu verbessern. Selbstverständlich kann die Manschette, statt mit der gezeigten elektrischen Widerstandsheizung auch durch andere bekannte Heizungen beheizt werden, wie z.B. eine Induktionsheizung.Drawing T shows a further claimed form, in which for thick-walled Hollow profiles, the inner heating (8) is conical, so see in the Inside the pipe a temperature gradient builds up even better. Also the The external heater (3) is conical here to accommodate the temperature gradient to improve. Of course, instead of the electrical resistance heater shown, the cuff can also be provided with other known heaters such as induction heating.
