Definitions

  • the invention relates to an axially divided intermediate ring or cutting ring for the lower knife shaft in longitudinal cutting machines, the surfaces of the separating joints perpendicular to the end faces of the ring being congruent with one another and meanderingly eroded from a full ring, so that the central radial separating surface section is removed over part of its radial extent , and a spacer element bridging the erosion gap in the circumferential direction is fastened between the central radial surface sections of the two separation points of each ring composed of two ring segments.
  • Such rings are known from DE-C 3 042 621 and have the advantage that they can be easily replaced, despite the fact that they are inexpensive to manufacture, if the cutting width program of the circular knife machine is to be changed. To do this, only the axial clamps on both ends of the lower knife shaft have to be loosened, whereupon the segments of the ring to be replaced are pushed apart axially and removed and possibly replaced by another ring, without the other rings having to be removed from the lower knife shaft. Finally, all rings are axially clamped against each other from the end faces of the lower knife shaft, and thereby fixed. Thus, the cutting widths can only be varied in stages, with a corresponding number of rings that are usually graduated in whole millimeters having to be kept in stock.
  • the dowel pins which are secured against unintentional falling out, for example by the centrifugal force during operation, expediently by means of overlapping retaining screws, result in an axially backlash-free coupling of the cutting ring segments, which is essential, above all for cutting sleeves, because the cutting edges formed by two ring segments must not be interrupted by joints or protrusions .
  • only one anti-rotation element per ring is required per ring, for example a radial clamping screw with a non-ferrous metal clamping plate, which prevents damage to the shaft surface when the clamping screw is tightened.
  • the ring segments 1, 2 each have two diagonally opposed separating surfaces which are produced by spark erosion and are interrupted twice and run perpendicular to the end faces.
  • the respective central surface sections in the circumferential direction are distanced by a grub screw 10, which was screwed in from a threaded hole of the meander in the right-hand segment 2 in FIG the left segment 1 just by the thickness of the spark erosion gap from the central radial surface section of the right segment 2.
  • the corresponding cutting edges 7 of the respective segment halves 1, 2 lie against one another without joints.
  • a dowel pin 5 is inserted into a corresponding radial fitting bore 8 formed by the adjacent ring segments in each coupling zone and then secured against falling out by the screw 6 with a washer.
  • the cutting sleeve as a whole can be continuously adjusted axially on the smooth lower knife shaft according to the desired cutting width program, whereupon the radial clamping screw 3 is tightened and the non-ferrous metal clamping plate 9 below is gently pressed onto the smooth shaft. The procedure for removing the cutting sleeve is reversed.

1. Anneau d'espacement ou anneau coupant fractionné axialement pour l'arbre du couteau inférieur sur des machines pour coupe longitudinale, les surfaces des joints de séparation, perpendiculaires aux faces frontales de l'anneau, étant érodées par étincelage à partir d'un anneau complet, de manière à obtenir des surfaces coïncidentes, en vis-à-vis et en forme de méandre, de sorte que la partie centrale de la face radiale de séparation est enlevée sur une partie de son étendue radiale, et un élément d'espacemant (10) recouvrant périphériquement la fente obtenue par érosion étant fixé entre les parties centrales des surfaces radiales des deux joints de séparation de chaque anneau constitué de deux segments d'anneau (1, 2), caractérisé en ce que chacun des joints de séparation est traversé par une goupille de positionnement radiale (5), et l'anneau (1, 2) présente au moins, un élément (3), en soi connu, d'immobilisation en rotation par rapport à l'arbre du couteau inférieur.
2. Anneau selon la revendication 1, caractérisé en ce que l'élément d'immobilisation en rotation (3) est réalisé sous la forme d'une vis d'arrêt avec une plaque d'arrêt (9) en métal lourd non ferreux.
3. Anneau selon la revendication 1 ou 2, caractérisé en ce que la goupille de positionnement (5) est bloquée par une vis fixation (6) qui la recouvre.
4. Anneau selon l'une quelconque des revendications précédentes, caractérisé en ce que l'élément d'espacement est une vis sans tête (10), vissée en partie dans un trou fileté prévu dans la partie centrale de la surface radiale d'un segment (2).
5. Procédé pour la fabrication d'anneaux fractionnés axialement pour les arbres de couteaux sur des machines pour coupe longitudinale, les surfaces des joints de séparation, perpendiculaires aux faces frontales de l'anneau s'étendant de manière coïncidente, en vis-à-vis et de préférence en forme de méandre, caractérisé en ce que les joints de séparation sont entièrement ébauchés à partir d'au moins un anneau complet par une opération d'électro-érosion, à la suite de quoi les segments d'anneau (1, 2) sont conjointement enfilés et serrés sur l'arbre du couteau inférieur, puis le finissage s'effectue sur l'anneau complet trempé, serré et bloqué par des goupilles de positionnement.
