Description
Damit Riemen aus plastischem Kunststoff, -beispielsweise aus Polyamiden, Polyurethanen u. a., nach Verlassen der Schneckenpresse, in der sie hergestellt werden, im verkürzten Verfahren die richtige Oberflächenbeschaffenheit und'die genau profilierte Stärke bekommen, um sie anschließend zur Verbesserung ihrer Festigkeitseigenschaften der R:eckmaschine zuführen zu können, muß eine mechanische Zwischenbehandlung eingeschaltet werden. So that belts made of plastic, e.g. made of polyamides, Polyurethanes, inter alia, after exiting the screw press in which they were manufactured are, in the shortened process, the correct surface quality and'the exact Get profiled strength in order to subsequently improve their strength properties To be able to feed the bending machine, a mechanical intermediate treatment must be switched on will.
Nach dem bisherigen Verfahren war es notwendig, das die Schneckenpresse verlassende Endprodukt in noch warmem, bildsamem Zustande einen längeren Luftweg zwischen Rollen und Walzen durchlaufen zu lassen, um eine Abkühlung zu erreichen. Dabei haben sich naturgemäß die Riem,en ih gewissen Grenzen noch deformiert, und eine genaue Maßhaltigkeit war nicht zu erreichen.According to the previous method it was necessary to use the screw press The end product leaves a longer airway when it is still warm and malleable to pass between rollers and rollers in order to achieve a cooling. Naturally, the straps have deformed within their limits, and exact dimensional accuracy could not be achieved.
Die Nachteile werden gemäß. der Erfindung dadurch vermieden, daß die Kunststoffriemen in noch warmem, plastischem Zustande unter geringem Druck eine mechanische Nachbehandlung erfahren. The disadvantages are according to. the invention avoided that the plastic belts while they are still warm and plastic under low pressure experience mechanical aftertreatment.
Hierbei wird sowohl eine Glättung der Oberfläche als auch eine Kalibrierung in der- Stärke des Materials erzielt.This involves both a smoothing of the surface and a calibration achieved in the strength of the material.
Eine geeignete Vorrichtung zur Durchführung den Verfahrens besteht gemäß der Erfindung aus zwei einander gegenüberliegenden gekühlten Walzenpaaren, über welche endlose Metallbänder laufen, sowie ' zwei über und unter den Metallbändern angeordneten Behältern, die von einer Kühlflüssigkeit durchströmt werden-und deren Abstand voneinander einstellbar ist. Durch diese Behälter wird gleichzeitig ein Druck auf die Metallbänder und damit auch auf den zwischen diesen Metallbändern hindurchgeführten Kunststoffriemen ausgeübt, wobei dieser gleichzeitig gekühlt und genau kaltilbriert wird. There is a suitable device for carrying out the method according to the invention of two opposing pairs of cooled rollers, over which endless metal belts run, as well as two above and below the metal belts arranged containers through which a cooling liquid flows - and their Distance from each other is adjustable. Through this container a Pressure on the metal bands and thus also on the one between these metal bands plastic belts passed through, which are cooled and at the same time is precisely cold-etched.
In der Zeichnung ist die Vorrichtung in einem Ausführungsbeispiel gemäß der- Erfindung veranschaulicht, und zwar zeigt Abb. I eine Ansicht der Vorrichtung von der Seite bei abgenommener Seitenplatte und Abb.. 2 -einen Schnitt nach der.Linie.X-24 der Abb. 1. In the drawing, the device is in one embodiment illustrated according to the invention, namely Fig. I shows a view of the device from the side with the side plate removed and Fig. 2 - a section along the line.X-24 of Fig. 1.
Hierbei bedeuten a die beiden Walzenpaare, b die endlosen Metallbänder, c die Stellschraube zur-Einstellung der Walzen, d die Walzenachsen, die durchbohrt sind zwecks Einführung von Kühlwasser in -das -Walzeninnere, e, f die beiderseits der endlosen Metallbänder angeordneten Kühlkästen, von welchen der untere Kühlkasten e feststeht, während der. obere Kühlkasten f durch eine Stellschraube g auf und ab gesenkt werden kann zwecks Ausübung eines Druckes auf die endlosen Metallbänder. Bei dieser Bewegung wird der obere Kühlkasten f durch die-weiteren SchraubenS geführt. i bezeichnen die Eintrittsöffnungen für die Kühlflüssigkeit, k die Austrittsöffnungen. Diese beiden Kühlkästen wirken als- Preßbalken zwecks Einstellung des Zwischenraumes zwischen den Metallbändern entsprechend der - gewünschten Stärke des Riemens 1. Der ausgeübte Druck entspricht dem Eigengewicht der Kästen - einschließlich Wasserfüllung. Da auch die Walzen gekühlt sind, erfährt der Riemen auf der -ganzen, zwischen den Metallbändern durchlaufenen Strecke eine Abkühlung, so daß er in gekühltem Zustande, mit glatter Oberfläche und in der gewünschten Stärke der Reckmaschine zugeführt werden kann. Here a denotes the two pairs of rollers, b the endless metal belts, c the adjusting screw for adjusting the rollers, d the roller axles that pierced are for the purpose of introducing cooling water into the interior of the rollers, e, f on both sides of the endless metal belts arranged cooling boxes, of which the lower cooling box e is established while the. Upper cooling box f by an adjusting screw g on and Ab can be lowered for the purpose of exerting pressure on the endless metal belts. During this movement, the upper cooling box f is guided through the additional screws S. i denote the inlet openings for the cooling liquid, k the outlet openings. These two cooling boxes act as a pressure beam for the purpose of adjusting the gap between the metal bands according to the - desired strength of the belt 1. The pressure exerted corresponds to the dead weight of the boxes - including the water filling. Since the rollers are also cooled, the belt experiences on the whole, between the Metal strips traversed a cooling, so that it is in a cooled state, fed to the stretching machine with a smooth surface and in the desired thickness can be.
