Description
Beschreibung
Hohlkörper, wie z. B. Rohre, Behälter, Hohlzylinder u. dgl., werden
heute aus den verschiedensten Gründen mit Kunststoffauskleidungen versehen. So dienen
diese Auskleidungen vielfach als Schutz gegen chemische Einwirkungen. Es ist weiter
bekannt, bei Drehautomaten die zum Zuführen des Stangen-oder Rohrmaterials dienenden
stählenen Führungsrohre mit Kunststoff, wie z.B. Polyäthylen, Polyamid od.
In der Praxis hat sich nun herausgestellt, daß die heute üblichen
So hat sich z. @. gezeigt, daß sich die auf die geschilderte Weise in den Führungsrohren befestigten Kunststoffauskleidungen infolge der ständigen starken Erschütterungen durch das geführte Werkstück mit der Zeit doch lockern. Ähnliche Erscheinungen zeigten sich auch an anderen Zwecken dienenden kunststoffausgekleideten Hohlkörpern bei starken mechanischen Beanspruchungen derselbeno Auch an geschlitzten Werkstoff-Führungsrohren lösten sich die Kunststoffauskleidungen nach gewisser Zeit an den Schlitzen ab und bogen sichdann nach innen.So has z. @. shown that in the manner described Plastic linings fixed in the guide tubes as a result of the constant However, over time, loosen strong vibrations from the workpiece. Similar phenomena were also found on plastic-lined items used for other purposes Hollow bodies with strong mechanical stresses the same o Also on slotted ones Material guide tubes, the plastic linings loosened after a certain time at the slits and then curved inward.
Ziel der Erfindung ist es, Lockerungen und Ablösungen der Kunststoffauskleidungen

Bei langgestreckten Hohlkörpern, wie z.B. Rohren, kann @s vorteil-
Um an mit Schlitzen versehenen Hohlkörpern Ablösungen der Kunststoffauskleidungen an den Schlitzen zu vermeiden, kann es weiter von Vorteil sein, gemäß weiterem Vorschlag Bohrungen od. dgl. auch längs der beiden Seiten der Schlitze in den Wänden der Hohlkörper anzuordneun, Zweckmäßig kann es sein, um hier die Auskleidungen im erwärmten Zustand durch eingeführtes Preßgas an die Innenseiten der Hohlkörper pressen zu können und ein Eindringen des Kunststoffes in die Bohrungen zu ermöglichen, die Schlitze erst nach dem Eindringen und Befestigen der Kunststoff Auskleidungen herzustellen.In order to detach the plastic linings on hollow bodies provided with slots to avoid at the slots, it can be further advantageous, according to another suggestion Bores or the like also along the two sides of the slots in the walls of the hollow body It can be useful to place the linings here in a heated state by injected compressed gas to the inside of the hollow body press to be able to and to allow penetration of the plastic into the holes that Make slots only after the plastic linings have penetrated and fastened.
