Beschreibung
Die Erfindung betrifft eine Walze. Description
The invention relates to a roller.
in Druckmaschinen, Maschinen zur Herstellung von Kunststofffolien und ähnlichen Maschinen werden Walzen verwendet, die eine verschleißfeste Außenfläche haben müssen und auf hohe Genauigkeit bearbeitet sein müssen. Stellt man derartige Walzen massiv aus dem verschleißfesten Metall (in der Regel legierter Stahl) her, so sind die Walzen teuer und schwer.In printing machines, machines for producing plastic films and similar machines, rollers are used that must have a wear-resistant outer surface and must be machined to a high degree of precision. If such rollers are made from solid wear-resistant metal (usually alloyed steel), the rollers are expensive and heavy.
Durch die vorliegende Erfindung soll eine Walze geschaffen werden, die an ihrer Oberfläche gleiche Verschleißfestigkeit aufweist wie eine massive Walze a'..,-s verschleißfestem Metall, welche aber leichter und billiger ist.The present invention is intended to create a roller which has the same wear resistance on its surface as a solid roller made of wear-resistant metal, but which is lighter and cheaper.
Diese Aufgabe ist erfindungsgemäß gelöst durch eine Walze gemäß Anspruch 1.This object is achieved according to the invention by a roller according to claim 1.
Bei der erfindungsgemäßen Walze ist die durch Spritzen aufgebrachte Metallschicht einerseits mit den scharfkantigen Partikeln verhakt und verbunden, die ihrerseits über eine Kleberschicht mit dem aus Kunststoff bestehenden Walzenkern verbunden sind. Zudem haften andere Abschnitte der Metallschicht direkt über die Kleberschicht am Walzenkern. Man erhält so eine derart feste Anbringung der durch Spritzen hergestellten Metallschicht auf dem Walzenkern, daß diese Schicht mechanisch durch überdrehen oder Uberschleifen bearbeitet werden kann.In the roller according to the invention, the metal layer applied by spraying is on the one hand hooked and connected to the sharp-edged particles, which in turn are connected to the plastic roller core via an adhesive layer. In addition, other sections of the metal layer adhere directly to the roller core via the adhesive layer. This results in the metal layer produced by spraying being attached to the roller core so firmly that this layer can be machined by turning or grinding.
Bei der erfindungsgemäßen Walze ist nur eine einzige Metallschicht vorhanden, die aus dem die Verschleißfestigkeit gewährleistenden metallischen Material besteht.In the roller according to the invention there is only a single metal layer, which consists of the metallic material that ensures wear resistance.
Vorteilhafte Weiterbildungen der Erfindung sind in ünteran-Advantageous developments of the invention are described in

Nachstehend wird die Erfindung anhand eines Ausführungsbeispieles unter Bezugnahme auf die Zeichnung näher erläutert. in dieser zeigt die einzige Figur einen axialen Schnitt durch einen Teil einer Walze (nicht maßstäblich, um den Schichtaufbau besser zeigen zu können).The invention is explained in more detail below using an embodiment with reference to the drawing. in this, the only figure shows an axial section through part of a roller (not to scale in order to better show the layer structure).
In der Zeichnung ist ein Halbschnitt durch einer. Teil eines Walzenkernes 10 wiedergegeben, der aus thermoplastischem Kunststoff, faserverstärktem Kunststoff oder geschäumtem Kunststoff, insbesondere geschäumtem Polyurethan bestehen kann.The drawing shows a half-section through part of a roller core 10, which can consist of thermoplastic, fiber-reinforced plastic or foamed plastic, in particular foamed polyurethane.
Auf den Walzenkern 10 ist eine Kleberschicht 12 durch Auftragen mit einer Spritzpistole oder unter Verwendung eines Rakels aufgebracht. Der verwendete Kleber ist ein Kleber auf Epoxy-Basis und enthält auf 100 Gewichtsteile Binder etwa 50 Gewichtsteile Härter. Der Härter setzt sich seinerseits aus zwei Komponenten zusammen, nämlich aus einem bei Zimmertemperatur aushärtenden Härter und einem bei hohen Temperaturen aushärtenden Härter. Von den 50 insgesamt auf den Härter entfallenden Gewichtsteilen kann der Anteil an Hochtemperatur-Härter zwischen 8 und 20 Gewichtsteilen betragen.An adhesive layer 12 is applied to the roller core 10 by means of a spray gun or using a doctor blade. The adhesive used is an epoxy-based adhesive and contains approximately 50 parts by weight of hardener per 100 parts by weight of binder. The hardener is in turn made up of two components, namely a hardener that hardens at room temperature and a hardener that hardens at high temperatures. Of the total 50 parts by weight of hardener, the proportion of high-temperature hardener can be between 8 and 20 parts by weight.
In die noch nicht ausgehärtete Kleberschicht sind mit einer Strahlkanone scharfkantige mineralische Partikel 14 eingeschossen, z.B.Korundpartikel - Die Korngröße der Partikel 14 ist so auf die Dicke der Kleberschicht 12 abgestimmt, daß jeweils ein innenliegender Abschnitt der Partikel 14 in die Kleberschicht 12 eingebettet ist, während sie mit einem außenliegenden Abschnitt über die Kleberschicht überstehen.Sharp-edged mineral particles 14, e.g. corundum particles, are shot into the not yet hardened adhesive layer using a jet gun. The grain size of the particles 14 is matched to the thickness of the adhesive layer 12 in such a way that an inner section of the particles 14 is embedded in the adhesive layer 12, while an outer section protrudes above the adhesive layer.
Das Aufblasen der Partikel 14 auf die Kleberschicht 12 erfolgt ferner in solcher Konzentration, daß die Partikel 14 dieThe particles 14 are blown onto the adhesive layer 12 in such a concentration that the particles 14
2038.2/RO/p - 3 - 3.11.19862038.2/RO/p - 3 - 3.11.1986
Kleberschicht 12 nicht vollständig bedecken, vielmehr zwischen den einzelnen Partikeln 14 jeweils Abschnitte der Kleberschicht 12 freibleiben.Adhesive layer 12 is not completely covered, but rather sections of the adhesive layer 12 remain free between the individual particles 14.
Auf die so mit Partikeln 14 besetzte, noch nicht ausgehärtete Kleberschicht 12 wird dann eine Spritzmetallschicht 16 aufgetragen, z.B. durch Plasmaspritzen oder Spritzen im Lichtbogen. Als Material für die Spritzmetallschicht findet ein verschleißfestes Metall bzw. eine verschleißfeste Legierunq Verwendung, z.B. ein verschleißfester legierter Stahl.A spray metal layer 16 is then applied to the adhesive layer 12, which is thus covered with particles 14 and has not yet hardened, e.g. by plasma spraying or arc spraying. A wear-resistant metal or a wear-resistant alloy, e.g. a wear-resistant alloyed steel, is used as the material for the spray metal layer.
Das Material der Spritzmetallschicht 16 verklammert sich zum einen an den über die Kleberschicht 12 überstehenden scharfkantigen Abschnitten der Partikel 14 und haftet auch an deren von Kleber freien Oberfläche. In den nicht mit Partikeln besetzten Abschnitten der Kleberschicht 12 erhält man eine direkte Klebverbindung zwischen der Spritzmetallschicht und dem Walzenkern 10.The material of the sprayed metal layer 16 clings to the sharp-edged sections of the particles 14 that protrude above the adhesive layer 12 and also adheres to their surface that is free of adhesive. In the sections of the adhesive layer 12 that are not covered with particles, a direct adhesive bond is obtained between the sprayed metal layer and the roller core 10.
Die Spritzmetallschicht 16 wird in einer Dicke aufgetragen, die mit Sicherheit größer ist als die höchsten Abschnitte von Partikeln 14. Die Spritzmetallschicht 16 wird anschließend zur Erzeugung einer glatten Walzenaußenfläche mechanisch spanend bearbeitet, z.B. überdreht und überschliffen, wie bei 18 gezeigt.The spray metal layer 16 is applied in a thickness that is certainly greater than the highest sections of particles 14. The spray metal layer 16 is then machined to produce a smooth outer roller surface, e.g. turned and ground, as shown at 18.
In der Praxis können die scharfkantigen Partikel 14 eine Korngröße von etwa 0,1 bis etwa 1 mm aufweisen, wobei die Dicke der Kleberschicht 12 entsprechend so angepaßt wird, daß ein nennenswerter Abschnitt der Partikel 14 unbedeckt aus der Kleberschicht 12 herausragt. Als Material für die scharfkantigen Partikel 14 kommen neben Korund auch andere mineralische Stoffe in Frage, z.B. gemahlenes Glas oder Sand.In practice, the sharp-edged particles 14 can have a grain size of about 0.1 to about 1 mm, with the thickness of the adhesive layer 12 being adjusted accordingly so that a significant section of the particles 14 protrudes uncovered from the adhesive layer 12. In addition to corundum, other mineral substances can also be used as material for the sharp-edged particles 14, e.g. ground glass or sand.

Die Spritzmetallschicht 16 kann auch aus einem anderen Metall oder einer anderen Legierung bestehen/ z.B. aus Bronze, wenn dies im Hinblick auf die Oberflächeneigenschaften der Walze gewünscht wird. 5The spray metal layer 16 can also consist of another metal or another alloy, e.g. bronze, if this is desired with regard to the surface properties of the roller. 5
