Definitions

  • the present 'invention relates to a hot-stamping cylinder made of metal, having arranged in the cylinder cavity heating.
  • a hot-stamping cylinder made of metal having arranged in the cylinder cavity heating.
  • printing or embossing cylinders for hot stamping processes were heated with oil by filling the interior of the cylinder with oil and connecting it to an oil circuit with an external oil heating unit.
  • Another method of heating the cylinders is based on the use of an electrical heating cartridge in the middle of the cylinder with energy supply via slip rings.
  • the object of the present invention was to design a heating system for heat embossing cylinders in such a way that the known disadvantages no longer occur, optimized heat distribution is possible and the whole can be achieved with the simplest possible means.
  • This object was achieved according to the invention in a hot stamping cylinder of the type defined in the introduction by the features of the characterizing part of claim 1.
  • a simple clamping of the tools in the desired position on the cylinder can be achieved (expansion or shrinkage of the cylinder jacket greater than that of the ring-shaped or sleeve-shaped tools).
  • the thinnest possible cylinder made of aluminum with brass tools is used.
  • the thermal expansion of the cylinder is used as a clamping device for the tools.
  • the heating power 'in predetermined areas for example, be higher at the cylinder end to compensate for the higher heat loss through the cylindrical bearing.
  • a uniform contact pressure of the heating foil against the inner wall of the cylinder is preferably achieved by expansion clamps, which at the same time enable the heating foil to be replaced quickly and easily if necessary.
  • the thinner the wall of the cylinder the lower its heat capacity and the faster the heating and cooling times, and thus the faster the reactivity with non-constant heat flow during operation.
  • the cooling time can also be significantly reduced by additional forced air cooling of the cylinder (cooling fan).
  • the surface temperature of the cylinder is preferably regulated to a desired temperature and kept constant.
  • a temperature sensor belongs to the control, which e.g. is integrated in the heating foil, in the cylinder jacket or otherwise inside the cylinder.
  • the subject of the invention enables a much easier process change in the pressure part (stamping part), a much more homogeneous heat distribution on the stamping cylinder (also in peripheral zones), a constant working temperature thanks to fast temperature control, short warm-up and cool-down times and a high efficiency thanks to local heat generation.
  • the heating elements heatating foils
  • the invention also allows simple attachment of the tools due to the thermal expansion occurring between the cylinder and the tools (shrinking, clamping).
  • FIG. 1 shows a longitudinal section through a hot stamping cylinder according to the invention
  • Fig. 2 shows a cross section through a cylinder according to Fig. 1 (on an enlarged scale).
  • the hot stamping cylinder 1 shown in the drawing has a cylinder jacket 2 made of aluminum and a. heating film 3 pressed against the inner wall of the cylinder, the pressing being carried out by means of a plurality of resilient expansion clamps 4 (the clamps 4 can be arranged at a mutual distance or directly adjacent to one another).
  • the cylinder 1 is in a manner known per se
  • Stamping tools 10 made of brass are placed on the cylinder outer surface (they are held in the set position by thermal expansion of the cylinder jacket 2).
  • a temperature sensor 11 is integrated in the cylinder wall.
  • the electrical connections of both the sensor 11 and the heating foil 3 (energy supply) are made via conductors (schematically designated 11 'or 3') which are arranged in the rotating cylinder 1 and in a known manner to slip rings 11 '' or 3 '' to lead.
  • the heating film 3 made of heat-resistant metal, has a large number of conductors which are matched to the local requirements (looks similar to a perforated plate or an expanded metal film).
  • the geometric design is similar to a perforated plate or an expanded metal film.
  • the heating foil 3 is preferably covered on both sides with a thin mica-like layer 12, 13 (FIG. 2). Towards the inside of the cylinder, the heating film 3 is also covered with an insulating mat 14 (FIG. 2), which comes to lie between the heating film 3 and the clips 4 (heat insulation against the inside).
  • the heating foil 3 and clips 4 can be inserted into the cylinder 2 from the side with the hub 6 removed.
