Fig. 4 Profil des Messers zum Längsschneiden von Papierbahnen/-strängen. Fig. 4 Profile of the knife for longitudinally cutting paper webs / strands.
Ein Schneidmesser 1 z. B. für einen Schneidmesserzylinder zum Querschneiden oder Längsschneiden einer Papierbahn oder eines Papierbahnstranges in einem Falzapparat weist an seiner dem Druckträger zugewandten Seite eine Schneidkante 4 auf. Zwei an der Schneidkante 4 beginnende Schneidflächen 2; 3 verlaufen in einem Öffnungswinkel Alpha < 90°.A cutting knife 1 z. B. for a cutting knife cylinder for cross cutting or longitudinal cutting of a paper web or a paper web strand in a folder has a cutting edge 4 on its side facing the printing medium. Two cutting surfaces 2 beginning at the cutting edge 4 ; 3 run in an opening angle alpha <90 °.
Die Schneidkante 4 kann durchgehend ausgebildet sein oder nebeneinander angeordnete Zähne 6 aufweisen.The cutting edge 4 can be continuous or have teeth 6 arranged next to one another.
Das Schneidmesser 1 besteht aus Metall, z. B. bekanntem Werkzeugstahl. Nur eine der beiden Schneidflächen 2 oder 3 ist von der Schneidkante 4 aus verlaufend über einen Teil einer Breite oder über eine gesamte Breite a sowie über die gesamte Länge mit Hartstoffüberzug 7 zwischen 0,5 µm und dicker, z. B. 15 µm, beschichtet. Es ist bezüglich der Breite a des Hartstoffüberzuges 7 auch möglich, daß der Hartstoffüberzug 7 erst in der Nähe der Schneidkante 4, d. h. ca. 0,5 mm von der Schneidkante 4 entfernt beginnt.The cutting knife 1 is made of metal, e.g. B. known tool steel. Only one of the two cutting surfaces 2 or 3 is from the cutting edge 4 extending over part of a width or over an entire width a and over the entire length with hard material coating 7 between 0.5 microns and thicker, z. B. 15 microns coated. With regard to the width a of the hard material coating 7, it is also possible for the hard material coating 7 to begin only in the vicinity of the cutting edge 4 , ie approximately 0.5 mm from the cutting edge 4 .
Der Hartstoffüberzug 7 besteht aus einem Werkstoff aus der Gruppe der Metallcarbide, -nitride, -oxide, -boride der -silicide der Elemente der vierten bis sechsten Nebengruppe des Periodensystems, einzeln oder in Kombinationen verwendet. Dieser Hartstoffüberzug 7 wird z. B. mittels PVD-Beschichtungsverfahrens (physical vapour deposition) aufgebracht.The hard material coating 7 consists of a material from the group of metal carbides, nitrides, oxides, borides and silicides of the elements of the fourth to sixth subgroups of the periodic table, used individually or in combinations. This hard material coating 7 is z. B. applied by means of PVD coating method (physical vapor deposition).
Nach einer weiteren Ausführungsvariante kann eine der beiden Schneidflächen 2 oder 3 mit einer Substanz 8 dauerhaft beschichtet sein, welche aus metallfreien amorphen Kohlenstoffschichten "a-C : H" (auch "DLC"-Schichten-diamond-like-carbon-Schichten genannt), besteht. Diese amorphen Kohlenstoffschichten bestehen aus einem hoch quervernetzten Kohlenstoffnetzwerk, an das Wasserstoff angelagert ist. Diese amorphen Kohlenstoffschichten haben außer ihren ausgezeichneten tribologischen Eigenschaften auch noch eine hohe Härte (HV = 2000 - 3500) und einen extremen Verschleißwiderstand. Durch Modifizierung der Netzwerkstruktur Fluor (F), Silicium (Si), Sauerstoff (O) und Stickstoff (N) und den prozentualen Anteilen kann die Oberflächenenergie der DLC-Schichten beeinflußt werden und damit das Benetzungsverhalten, die Härte und der Verschleiß wahlfrei beeinflußt werden.According to a further embodiment one of the two cutting surfaces 2 or 3 may be coated permanently with a substance 8 which consists of metal-free amorphous carbon layers (also referred to as "DLC" -Schichten- d iamond- l IKE c arbon layers) "aC H" , consists. These amorphous carbon layers consist of a highly cross-linked carbon network to which hydrogen is attached. In addition to their excellent tribological properties, these amorphous carbon layers also have high hardness (HV = 2000 - 3500) and extreme wear resistance. By modifying the network structure fluorine (F), silicon (Si), oxygen (O) and nitrogen (N) and the percentages, the surface energy of the DLC layers can be influenced and thus the wetting behavior, hardness and wear can be influenced optionally.
Es kann auch DLC + Fluor (F-DLC); DLC + Silicium (Si-DLC), DLC + Sauerstoff (O-DLC) und DLC + Stickstoff (N-DLC) und DLC + Bor (B-DLC) verwendet werden. Besonders geeignet sind F-DLC und Si-DLC.It can also use DLC + fluorine (F-DLC); DLC + silicon (Si-DLC), DLC + oxygen (O-DLC) and DLC + nitrogen (N-DLC) and DLC + boron (B-DLC) can be used. F-DLC and Si-DLC are particularly suitable.
Eine Beschichtung mit den Substanzen 8 erfolgt in einer Dicke, die zwischen 0,5 und 10 µm liegt.A coating with the substances 8 takes place in a thickness that is between 0.5 and 10 μm.
Während der Benutzung des so behandelten Schneidmessers 1 wird das Metall, z. B. der normale Werkzeugstahl infolge Verschleißes ausgearbeitet, so daß die nichtbeschichtete Schneidfläche 3 eine Aushöhlung 9 erhält, wodurch ein Selbstschärfeffekt des Schneidmessers 1 eintritt.While using the cutting knife 1 treated in this way, the metal, e.g. B. the normal tool steel as a result of wear, so that the uncoated cutting surface 3 receives a cavity 9 , whereby a self-sharpening effect of the cutting knife 1 occurs.
Bei dem Einsetzen des Schneidmessers 1 in den Schneidzylinder zum Querschneiden einer Papierbahn oder -stranges ist darauf zu achten, daß stets die nachlaufende Schneidfläche 2 des Schneidmessers 1 den Hartstoffüberzug 7 bzw. die Substanz 8 aufweist, da die vorlaufende Schneidfläche 3 eine "schabende" Bewegung in der Schneidnut der Gegenschneidleiste 5 ausführt, welche einen gewollten Verschleiß des Werkzeugstahls zur Folge hat, der den Selbstschärfeffekt herbeiführt. Diese "schabende" Bewegung des Schneidmessers 1 ist auf eine höhere Umfangsgeschwindigkeit der Schneidkante 4 gegenüber der jeweiligen Umfangsgeschwindigkeit des Schneidmesserzylinders sowie des Gegenschneidzylinder zurückzuführen.When inserting the cutting knife 1 into the cutting cylinder for cross-cutting a paper web or strand, care must be taken that the trailing cutting surface 2 of the cutting knife 1 always has the hard material coating 7 or the substance 8 , since the leading cutting surface 3 has a "scraping" movement in the cutting groove of the counter-cutting bar 5 , which results in a deliberate wear of the tool steel, which brings about the self-sharpening effect. This "scraping" movement of the cutting knife 1 is due to a higher peripheral speed of the cutting edge 4 compared to the respective peripheral speed of the cutting knife cylinder and the counter-cutting cylinder.
Nach einer anderen Ausführungsvariante kann auch analog eine einseitige Beschichtung einer endlosen, d. h. ringförmigen Schneidfläche eines Kreismessers mit dem Hartstoffüberzug 7 oder der genannten Substanz 8 in seinem Randbereich erfolgen. Solche Kreismesser werden zum Längsschneiden von Papierbahnen verwendet. Beim Einbau eines jeden Kreismessers ist darauf zu achten, daß eine Sollverschleißseite jeweils z. B. mit einer harten bzw. beschichteten Kante oder Fläche der umlaufenden Schneidnut einer Nutwalze zusammenwirkt, um eine Selbstschärfeffekt herbeizuführen.According to another embodiment variant, a one-sided coating of an endless, ie annular cutting surface of a circular knife with the hard material coating 7 or the substance 8 mentioned can also take place in its edge region. Such circular knives are used for slitting paper webs. When installing each circular knife, make sure that a target wear side z. B. interacts with a hard or coated edge or surface of the circumferential cutting groove of a grooving roller to bring about a self-sharpening effect.
