Abstract

Profiled members of thermosetting plastics are continuously produced by pressing with double-layer belts, comprising steel belts to accept tension and compression with plastic belts to provide the desired shape.

Description

Doppelband-Pressverfahren zur kontinuierlichen Herstellung von Formlingen und Profilen aus Duroplasten Formlingen und Profilen aus Duroplasten Die Neuerung bringt gegenüber den bekannten Herstellungsverfahren die Vorteile der kontinuierlichen Herstelluhg von gepressten Profilen, Formlingen oder großflächiger Platten mit reliefartigen Strukturen, Oberflächen mit hohem Glasgehalt und sehr guter Maßhaltigkeit.Double belt press process for the continuous production of molded products and profiles made of thermosetting plastics Moldings and profiles made of thermosetting plastics The innovation brings the advantages of continuous over the known manufacturing process Manufacture of pressed profiles, moldings or large-area panels with relief-like shapes Structures, surfaces with a high glass content and very good dimensional accuracy.

Die kontinuierliche Herstellung der Formlinge und Profile geschieht dadurch, daß durch die am Eingangsanfang konisch geführten glatten oder profillierten Bänder mehr Material bis zur Srweichungs- bzw, Verflüssigungszone gefördert werden als normal benötigt wird, Durch die laufende Aufhärtung kann der Druck nach vorn nicht weggehen und so entsteht am Anfang der Presszone ein relativ hoher Druck, der durch Veränderung der Eingangskonizität Fig. I/12 Materialeigen schaften und Fahrgeschwindigkeit auf die optimalen Erfordernisse eingestellt werden kann.The continuous production of the moldings and profiles takes place in that through the smooth or profiled conically guided at the beginning of the entrance Belts more material are conveyed to the softening or liquefaction zone than is normally needed, the ongoing hardening can push forward do not go away and this creates a relatively high pressure at the beginning of the press zone, by changing the input taper Fig. I / 12 material properties and Driving speed can be adjusted to the optimal requirements.

Beschreibung Auf die Druck- und zugkraftaufnehmenden Stahlbänder Fig. I/1 Fig. III/1 werden die formgebenden Kunststoffbänder aufgenommen Fig. I/2 Fig. III/2, die Stahlbänder werden sit einer Spannrolle Fig. I/3 in Spannung gehalten und die Kunststoffbänder durch einen Spannrollensatz Fig. I/4, die Zugräder für die Bänder Fig. I/5/6 haben einen synchronisierten Allradantrieb und sind an der Ober# fläche beheizbar. Ein oder mehrere Stahlbänder Fig. 11/1 können je nach rrofilart Kernstücke Fig. II/7 aufnehmen, diese Kernstücke werden gegeneinander an den Stirnseiten abgedichtet und stellen so auf einer geraden Ebene einen geschlossenen Kern dar Fig. In/8, der eick auf den Zug- und Wenderädern Fig. IIJ5 konisch aufspaltet Fig. II/7 und auf den geraden Ebenen wieder schließt und so einen endlosen Kern darstellt Fig. II/8. Die Kernstücke sind beheizbar0 Alle Bänder werden durch einen, an beiden Enden offenen, kastenförmigen Druckrahien Fig. I/9 und Fig. III/9 geführt und durch deren beheizbare und verstellbare Druckleisten Fig. I/11 und Fig. III/II die die Kallibrierung bzw. Einstellung der Wandstärke der Profile oder Formlinge Durch die Hydraulik Fig. I/10 und Fig. III/10 erfolgt das Längsverstellen des Druckrahmens Fig.Description of the pressure and tensile force absorbing steel strips Fig. I / 1 Fig. III / 1 the shaping plastic strips are taken up Fig. I / 2 Fig. III / 2, the steel belts are held in tension by a tensioning roller Fig. I / 3 and the plastic straps by a set of tensioning rollers Fig. I / 4, the pulling wheels for the belts Fig. I / 5/6 have a synchronized four-wheel drive and are on the Heatable surface. One or more steel strips Fig. 11/1 can, depending on the type of profile Pick up core pieces Fig. II / 7, these core pieces are against each other on the front sides sealed and thus represent a closed core on a straight plane Fig. In / 8, which tapered apart on the pulling and turning wheels Fig. IIJ5 Fig. II / 7 and closes again on the even levels and thus represents an endless core Fig. II / 8. The core pieces are heatable0 All tapes are through a box-shaped printing frame Fig. I / 9 and Fig. III / 9 open at both ends guided and through their heatable and adjustable pressure strips Fig. I / 11 and Fig. III / II the calibration or adjustment of the wall thickness of the profiles or moldings The hydraulic system Fig. I / 10 and Fig. III / 10 adjusts the printing frame lengthways Fig.

I/9 und Querverstellen des Antriebsrades Fig. I/6 wird der zum Druckaufbau der Duroplasten erforderliche Einlaufkegel Fig. I/12 eingestellt. Die Länge des Druckrahmens ist die Bearbeitungslänge in der das eingefahrene Material geformt und polymerisiert wird.I / 9 and transverse adjustment of the drive wheel Fig. I / 6 is used to build up pressure of the thermoset required inlet cone Fig. I / 12 set. The length of the The pressure frame is the processing length in which the inserted material is formed and is polymerized.

Zur Herabsetzung des R Reibungskoeffizientes zwischen den Stahlbändern Fig. 1/1, Fig. III/1 und den Druckleisten Fig. I/11 und Fig. III/11 im Druckrahmen Fig. I/9, Fig. 111/9 sind endlose Nadellager Fig. I/13 und Fig. III/13 eingebaut.To reduce the R coefficient of friction between the steel strips Fig. 1/1, Fig. III / 1 and the print bars Fig. I / 11 and Fig. III / 11 in the print frame Fig. I / 9, Fig. 111/9, endless needle bearings Fig. I / 13 and Fig. III / 13 are installed.

Als Beispiel wurde ein Querschnitt der Zeichnung Fig. III ein U-förmige6 Profil 14 mit Kern 8 dargestellt.As an example, a cross section of the drawing Fig. III was a U-shaped6 Profile 14 shown with core 8.

Anstelle des endlosen Profilkerns Fig. III/8 können auch aus Schäumen, Holz oder Metall bestehende, volle oder hohle, rohrförmige Kerne, in Durchlauf ummantelt bzw. beschichtet werden.Instead of the endless profile core Fig. III / 8, foams, Wood or metal, solid or hollow, tubular cores, encased in continuous flow or coated.
