Definitions

  • the invention relates to a cutting knife for cutting stacked, sheet-like material, the cutting knife having a wedge shape, with a Cutting surface and, for the material being cut, a deflecting surface at a wedge angle are arranged to each other and the line of intersection of the cutting edge of the cutting knife.
  • the invention further relates to a method for manufacturing of such a cutting knife.
  • Such cutting knives are used in particular to stack, sheet-like material, for example a stack of paper, in a pulling cut cut.
  • the good rests on a flat surface and it occurs if not is cut in the counter cut, the cutting knife in bottom dead center a cutting bar.
  • the cutting surface of the cutting knife defines the Cutting plane, while the cut material in the area of the deflecting surface of the Cutting knife is deflected.
  • the cut good is either for a benefit or for cutting waste.
  • Such devices for cutting stacked, sheet-like material are designed, for example, as single-knife cutting machines or three-knife trimmers.
  • DE 31 01 911 A1 describes a cutting machine in which the deflecting surface a brush device is assigned to the cutting knife. through This facility is intended to ensure that when lifting the Cutting knife adhering to the cutting knife after the cut has been made Cutting waste can be removed completely. In practice, this can be used in generally achieve satisfactory results. However, you cannot Always prevent material to be cut from getting stuck in the brush.
  • DE 34 44 952 A1 describes a cutting machine in which one separate blowing air nozzle is provided, with the blowing air in the direction of the deflecting surface of the cutting knife can be blown.
  • the air jet kicks in on the cutting knife essentially parallel to the deflecting surface.
  • Cutting knives are also known from the prior art, at where blown air is used to influence the cutting process. It but these are rotating cutting knives and devices for Cutting a leaf. Reference is made, for example, to DE 101 08 234 A1.
  • the object of the present invention is to provide a cutting knife of the input to create the type mentioned, which ensures that generated during the cut Cutting waste does not adhere to it. This should especially apply when cutting with the cutting knife material that tends to become charge electrostatically.
  • the object of the invention is also a method to specify for the manufacture of such a knife.
  • the task is solved with a cutting knife of the type mentioned in that there is in the area the deflecting surface with outlet openings for blowing air is provided.
  • the blowing air from the cutting knife emerges and consequently any cutting material which has a tendency to Sticking cutting knife is blown away by the cutting knife.
  • This is particularly so an advantage for material to be cut, which has the tendency to become electrostatic charge. This material to be cut is safely removed from the deflecting surface of the cutting knife blown away.
  • blowing air from the cutting knife through it Outlets.
  • the appropriate pressure level of the blown air is selected. It can do this absolutely compressed air, thus air with a relatively high pressure.
  • the blowing air can be directed through the cutting knife in different ways and way.
  • a structurally particularly simple design provided that holes in the cutting knife for the passage of the Blown air are integrated, with the holes in the area of the deflector Emerge from this.
  • the passage cross section for the blown air is essentially unchanged.
  • the holes can be very easily insert into the cutting knife.
  • Cutting knife nozzles are formed, for example, by the passages for the blowing air is in the direction of the outlet openings or in the region of the outlet openings taper conically.
  • the bores or passages for the blowing air are arranged parallel to the cutting surface of the cutting knife.
  • the cutting knife that this has a knife holder and a hard metal cutting edge inserted in it having. Both the knife holder and the carbide cutting edge are preferably provided with the deflecting surface.
  • the Bores and / or a connecting channel into which the bores open advantageously formed between the knife carrier and the hard metal cutting edge.
  • the blowing air is fed to the cutting knife, for example, by means of at least one hose, the side of the cutting knife, based on a side perpendicular to the cutting plane, with the cutting knife connected is.
  • This hose is connected to a compressed air source.
  • the cutting knife is preferred by first making channels in the Knife holder of the cutting knife are introduced.
  • the arrangement of the Channels are made according to the air flow in the cutting knife.
  • the knife holder is connected to the carbide edge of the cutting knife. Due to the arrangement of the knife carrier and carbide cutting edge the blow air passages formed in the cutting knife, which in the outlet openings lead.
  • there is no need to drill holes in it Introduce cutting knife but first the channels in the knife holder generated, especially by milling.
  • the channels are closed, to form the passages in the cutting knife, by connecting knife carriers and carbide cutting edge. This connection is made advantageously by Soldering.
  • the cutting knife shown in FIGS. 1 and 2 is found, for example, in a cutting machine use, as in DE 31 01 901 A1 or DE 37 13 897 A1 is disclosed.
  • the cutting knife 1 for cutting stacked, sheet-like material is wedge-shaped. It has a cutting surface 2 and a deflection surface 3 on. These are arranged at a wedge angle to each other. Their intersecting line forms the cutting edge 4 of the cutting knife 1.
  • the cutting knife 1 consists of a knife holder 5, which has a recess is provided for receiving a hard metal cutting edge 6.
  • the carbide cutting edge 6 is positioned with respect to the knife carrier 5 such that the deflecting surface sections 3a and 3b form a flat deflecting surface 3.
  • the cutting knife arranged side by side, has various hole arrangements 7, each hole arrangement 7 by three arranged one above the other Threaded bores 8 is formed. These are used to attach the Cutting knife 1, specifically the knife carrier 5 on a not shown Cutter bar of a cutting machine using screws.
  • the one above the other Arranged holes 8 are therefore provided to grind the Cutting knife 1 due to its regrinding, the reduced height extension to compensate for the cutting knife 1.
  • the cutting knife 1 penetrates, parallel to the cutting edge 4, an air duct 9, and a large number of further air ducts 10 extend vertically from it, whose outlet openings 11 are located in the area of the deflecting surface 3.
  • the air ducts 9 and 10 are produced by before soldering the hard metal cutting edge 6 to the knife carrier 5, grooves in the knife carrier 5 are milled in the area of the recess. In these Cutout of the knife carrier 5, the hard metal cutting edge 6 is then used and soldered to the knife carrier 5. When placing the hard metal cutting edge 6 on the knife carrier 5, the grooves are closed, making the Air channels 9 and 10 are formed. On opposite sides of the cutting knife 1, thus in the area of the outlet openings of the air duct 9 Connections 12 fastened with the cutting knife 1, with which hoses 13th get connected. Through this, compressed air becomes the air channels 9 and 10 fed.
  • the compressed air supply is preferably clocked so that it is in decline the cutting knife, thus when cutting, and when returning the Cutting knife is fed.
  • a connection between the cutter bar and the cutter holder be provided through which compressed air can be guided.
  • the Knife holder When attaching the Knife holder on the cutter bar are air holes in the cutter bar and coupled in the knife carrier.
  • the cutter bar or cutter carrier To provide coupling elements which when connected to the cutter bar Knife carriers interact and create a fluid-tight connection between ensure these parts. The cutting knife can be changed thus proceed as usual, automatically coupling the air connections he follows.
