Definitions

  • the invention relates to a device for cutting through, cutting, perforating or perforating sheet material, such as paper, metal foils or plastic foils, in particular label material located on a carrier material that is not to be affected, by means of a cutting disk that can be releasably coaxially clamped between an abutment disk and a pressure disk, the outside diameter of which is somewhat is larger than the outer diameter of the abutment plate and the pressure plate.
  • the cutting disc is provided on its periphery with a cutting edge which is subjected to considerable wear during cutting work or perforation work, which leads to increasingly blurred cutting edges or perforation edges in the sheet material , so that the cutting disc must be replaced relatively often.
  • the object of the invention is to provide a device of the type mentioned, the cutting disc is less susceptible to wear.
  • the device is characterized in that the cutting disk has such a small thickness that the cutting work or perforating work can be carried out with its peripheral surface.
  • the invention was based on the finding that a cutting disc with a rounded peripheral surface can perform cutting and perforating work, such a rounded peripheral surface is relatively susceptible to wear and tear and can perform evenly clean cutting or perforating work even after wear, if it has a sufficiently small thickness.
  • the circumferential surface runs from the beginning, ie before the first use of the cutting disc, in cross section essentially symmetrical to the central plane of the cutting disc and is rounded in the apex area.
  • the outside diameter of the cutting disk is 0.50 mm to 0.70 mm, preferably 0.55 mm to 0.65 mm, larger than the outside diameter of the abutment disk or the pressure disk depending on the which of these outer diameters is the larger so that the circumferential surface performing the cutting work or the perforating work is reliably guided during its work.
  • the thickness of the cutting disc is 0.08 mm to 0.19 mm, preferably 0.1 to 0.17 mm.
  • the cutting disc is preferably made of carbon steel or chrome steel.
  • the cutting disc works particularly reliably when the sheet material to be cut or perforated is supported on the side facing away from the cutting disc by a rotatably mounted abutment roller.
  • the circumferential surface - if not the entire body - of the abutment roller is preferably made of hardened steel.
  • a particularly economical method for producing the cutting disks discussed, but also / or cutting disks that do not meet the above-mentioned requirement for their thickness is characterized in that blanks are the ring-shaped cutting disks are punched out of a sheet metal, that a large number of these blanks (52) are then placed directly next to one another on a shaft as a package, clamped together on the shaft and ground as a package while rotating the shaft, so that the rounded grinding disks are then isolated horizontally by an etching device are promoted, in which they are sprayed from above and below with an etching liquid, and that the cylindrical and etched grinding wheels are then washed and dried.
  • the round-ground, etched, washed and dried grinding discs are placed as a package directly next to one another on a shaft and clamped together on the shaft and then into the package in the circumferential area axial grooves with a depth of 0.20 mm to 0.25 mm, preferably 0.21 mm to 0.24 mm, ground or milled.
  • Fig. 1 shows an apparatus for clamping a cutting disc in an exploded view.
  • FIG. 2 shows the area II in FIG. 1 on an enlarged scale.
  • FIG. 3 shows - not to scale - a peripheral area of a perforated disc from viewing direction III in FIG. 1.
  • Fig. 4 shows schematically the interaction of a device according to Fig. 1 in the assembled state with an abutment roller.
  • FIG. 5 shows an etching device in longitudinal section.
  • FIG. 6 shows a plan view of a grating carrying blanks in the viewing direction VI of FIG. 5.
  • Fig. 1 shows an abutment plate 2 with a predetermined outer diameter and a pressure plate 4 with substantially the same outer diameter.
  • An annular cutting disk 6 is interchangeably tensioned coaxially between the abutment disk 2 and the pressure disk 4, and its circumference 8 projects slightly around the outside diameter of the abutment disk 2 and the pressure disk 4.
  • the abutment disc 2 has a hub 10 which passes through a central hole 12 in the cutting disc 6 and a central hole 14 in the pressure disc 4 and is provided with an external thread 16 for screwing on a pressure ring 18.
  • There are holes 20 in the pressure ring 18 which can be engaged with a turning tool.
  • the circumference of the hub 10 next to the abutment disc 2 is designed as a guide surface 19 for the central hole 12 in the cutting disc 6.
  • the hub 10 has four axial rotation lock recesses 22 in its circumference, which merge into the abutment disk 2 through holes 24. Two of these anti-rotation recesses 22 cooperate with anti-rotation projections projecting radially inwards into the hole 12 of the cutting disk 6.
  • the abutment plate 2 and the pressure plate 4 are delimited on their circumference by conical surfaces 28, 30 facing one another with their bases.
  • a roller bearing - not shown - to be placed on a bearing axis.
  • the peripheral surface 30 of the cutting disc 6 extends in cross section essentially symmetrically to the central plane 32 of the cutting disc 6 and is rounded in its apex region 34. To the apex region 34 lead from the side surfaces 36 and 38 of the cutting disc 6 towards each other, in the cross section shown straight flanks 40, 42.
  • the outer diameter D6 of the cutting disc 6 is somewhat larger than the outer diameter D2 of the abutment disc 2 or larger by the amount mentioned than the outer diameter D4 of the pressure plate 4 depending on which of these outer diameters D2, D4 is larger.
  • FIG 3 shows the circumferential area of a cutting disk 6 formed with perforation webs 46.
  • the perforation webs 46 are separated from one another by gaps 48.
  • the dimensions of the webs 46 and the gaps 48 can be adapted to the respective requirements without difficulty.
  • Fig. 4 shows that the cutting disc 6 cooperates with the peripheral surface of a - rotatably mounted abutment roller 44, which serves to support the back of the sheet material and optionally the carrier of the sheet material.
  • the device according to FIG. 5 has a housing 50 with an entry slot (not shown) and an exit slot (not shown) for blanks 52 to be punched on both sides. These blanks 52 have previously been punched out of sheet metal and are conveyed through the housing 50 on a grating 68. In front of the housing, in the housing and behind the housing, the grating 68 is supported horizontally by rollers 54. In the housing 50 there are distribution pipes 56 and 58 for downward and upward directed nozzles 60, 62, from which etching liquid 64 for spraying the blanks 52 emerges from above and below. The etching liquid 64 collects in the bottom region 66 of the housing 50 and is fed back to the nozzles 60, 62 in a circuit, not shown.
