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 which is not to be affected, by means of a cutting disk which 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 disc and the pressure disc, the cutting disc being so thin that the cutting or perforating work is to be carried out with its peripheral surface.
  • a cutting disk which 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 disc and the pressure disc, the cutting disc being so thin that the cutting or perforating work is to be carried out with its peripheral surface.
  • a device is known from DE-A-4.006.611.
  • 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 leads, 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 disc has a peripheral surface, the cross section of which is substantially symmetrical to the central plane of the cutting disc and is rounded in its apex region, and that straight flanks are to be striven towards the apex region from the side surfaces of the cutting disc to lead.
  • the invention was based on the finding that a cutting disc with a rounded circumferential surface can perform excellent cutting work and perforating work, and is relatively susceptible to wear is, even after wear, can still perform a uniformly clean cutting or perforating work if it has only a sufficient thickness, which is achieved in that it has straight flanks to be strived for from side surfaces of the cutting disc.
  • the circumferential surface runs from the beginning, that is before the first use of the cutting disc, in cross section essentially symmetrically 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 this outer diameter 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 peripheral surface - if not the entire body - of the abutment roller is preferably made of hardened steel.
  • 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 in 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 region of a perforated disc from the 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 top view of a grating carrying blanks in 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 limited 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 disk 6 extends in cross section essentially symmetrically to the central plane 32 of the cutting disk 6 and is rounded in its apex region 34.
  • the outer diameter D 6 of the cutting blade 6 at said level slightly larger than the Outside diameter D 2 of the abutment disc 2 or larger than the outer diameter D 4 of the pressure plate 4 depending on which of these outer diameters D 2 , D 4 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 circumferential 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 inlet slot (not shown) and an outlet 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.
