Definitions

  • the invention relates to line cutting knives for processing flat materials, in particular for use in the paper, leather, plastic and the like processing industry, consisting of a band-shaped carrier material with a longitudinally, preferably by mechanical processing, created cutting edge area or with a cutting edge running on one or both sides along the belt and a coating.
  • Line cutting knives are used, for example, for the production of folding boxes or folding box blanks, for punching out adhesive-coated paper labels that adhere to peel-off foils, for creating uniformly shaped mass parts in the leather industry, for cutting out single and multi-layer and welded parts from plastic films and the like.
  • the thickness of the line cutting knives which should have a hardness of 40 to 48 HRc, is usually between 0.5 and 2 mm, whereby a high degree of elasticity of the material is required, so that when the knife band is bent into a holder, cutting patterns are also included small radii can be formed.
  • Line cutting knives are tools that are exposed to high mechanical stresses during use, whereby wear due to abrasion and chemical corrosion also limits their durability or service life. Also in the cutting processes due to surface friction from Dust that falls off the material to be cut is undesirable in many cases.
  • the invention had for its object to provide line cutting knives which, with a corresponding hardness of the base material of at least 40 to 48 HRc and with good bendability, at least in the cutting edge area, high strength against mechanical abrasion, a low tendency for adhesives to adhere and corrosion resistance against the chemical substances occurring during processing and thus have a longer service life, the paper and filler dust accumulating in practical operation possibly being low.
  • a single-layer or multilayer hard material layer is applied to the surface in the cutting edge region of a line cutting knife consisting of low-alloy stainless steel, in particular carbon steel, which layer consists of nitride and / or carbide and / or oxide and / or carbonitride and / or oxicarbonitride of the elements of groups IVb, Vb, VIb of the periodic system or of nitride of the elements boron, aluminum, and silicon is formed and may have different compositions of the individual layers. It is particularly advantageous if the coating is applied by means of the PVD method and the thickness of the hard material layer is 1 to 10 ⁇ m, preferably 3 to 5 ⁇ m. It is further preferred that the hard material layer consists of titanium carbonitride and / or titanium nitride.
  • a thickness of the hard material layer of 1 ⁇ m was an essential ver reduces the corrosion attack and from a layer thickness of 3 microns there is corrosion protection against chemical substances that are present when processing adhesive-coated plastic and leather materials, whereby the service life of the line cutting knife when processing such products and when exposed to moisture is essential is increased.
  • Line cutting knives according to the invention are described in more detail below with reference to drawings and their manufacture is explained.
  • 1 to 3 show schematic cross-sectional shapes of line cutting knives.
  • FIG. 1 a one-sided cutting line cutting knife is shown with grinding both band surfaces.
  • a cutting area 1 with a cutting line 2 of a band 3 is wedge-like, the wedge surfaces 4 and 4 'being inclined to the parallel surfaces of the band 3.
  • Fig. 2 shows a one-sided cutting line cutting knife with one-sided chamfer.
  • the cutting line 2 lies in one of the parallel surfaces of the belt 3 and forms with this and the wedge surface 4 a cutting area designed as an oblique wedge 1.
  • the wedge surface 4 ' which the part of the cutting line 2 facing Represents surface of the band 3, can also wear a hard material layer.
  • Fig. 3 is a double-sided line cutting Knives shown, with two cutting areas 1 and 1 'in a version, as shown in Fig. 1, arranged on a band 3.
  • a line cutting knife according to the invention is produced in that a strip made of a low-alloy steel, for example a carbon steel with a carbon concentration of 0.4 to 0.8% by weight carbon, is brought to a required thickness by hot and / or cold rolling, after which, if necessary, a heat treatment is carried out in a specific atmosphere to influence the strip surface.
  • a tempering consisting of at least one hardening and an annealing treatment is carried out on the strip produced in this way, whereupon one or two cutting edges and a required final dimension are set by a preferably mechanical processing.
  • a hard material layer is applied to the strip surface in the cutting edge area, preferably using a PVD process.
  • the band-shaped carrier part consisted of the material C60 (carbon steel with a carbon content of approximately 0.6% by weight).
  • Single-layer and multi-layer hard material layers made of titanium carbonitride (Ti (C, N)) and / or titanium nitride (TiN) were applied to tempered knife tapes with a hardness of 45 HRc, after which these line cutting knives parallel to those which had the conventional structure, were used in high-speed cutters.
  • the cutting number values were used or compared when determining and evaluating the tool life results posed. It was found that the line cutting knives according to the invention increase the service life of at least 65% when processing new paper.
