Definitions

  • the invention relates to an embossing device of the type specified in the preamble of claim 1.
  • Embossing devices with type wheels which have permanently mounted embossing elements (types).
  • An example EP-A-0 091 579 can be found for such a device.
  • these have the disadvantage that if a type is damaged or lost, it is necessary to procure a relatively expensive part again. Conversion to changed character combinations is also not possible.
  • a common disadvantage of these embossing devices is that the working speed is relatively limited because the stamping accuracy decreases at higher speeds.
  • the invention specified in the characterizing part of claim 1 is based on the object of specifying an embossing device of the type mentioned in the introduction, in which an exact positioning of the types with respect to the workpiece is ensured even at high working speeds.
  • the invention is based on the knowledge that the inaccuracies to be observed in the previous embossing devices have their cause in spinning movements of the embossing element fastened to an elastic spoke.
  • the embossing element has a relatively large weight to achieve a high stability. Since, on the one hand, relatively high accelerations are necessary at high working speeds and, on the other hand, the suspension of the embossing elements must be sufficiently elastic to accommodate the working stroke, the embossing elements do not have enough time at high working speed after braking to return to their rest position.
  • the measures according to the invention ensure, via an additional guide, that the types can only migrate insignificantly from their rest and embossing positions in the tangential direction. This ensures embossing with high precision.
  • the embossing elements are cylindrical, the chambers forming corresponding hollow cylindrical recesses in which the embossing elements slide to carry out the embossing stroke.
  • the hollow cylindrical recesses of the chambers are open towards the bottom and lid and thus passages for form the character shape to be embossed or the plunger pushing down the embossing element, neither the embossing process nor the access of the plunger to the rear surface of the embossing element is impeded.
  • the radially forming recesses are connected to the recesses forming the chambers, which receive the spoke when the embossing element is depressed for embossing.
  • the spokes are angled and open parallel to the axis of the embossing wheel.
  • the individual types together with their spokes can be easily replaced and are precisely positioned through holes in the embossing wheel, the ends of the embossing wheel being inserted into these holes parallel to the axis of the embossing wheel.
  • the inner ends of the spokes are secured against sliding out and twisting by means of a tension disk which presses the inner ends of the spokes against a radially directed stop surface of the embossing wheel.
  • the tensioning disk is advantageously screwed to the hub of the embossing wheel.
  • the embossing wheel consists of a light metal such as aluminum or titanium and, in the former case, is preferably provided with a coating of titanium, which increases the resistance of the surface.
  • the embossing wheel shown in FIG. 1 belongs to an embossing device of the type that corresponds in principle to the embossing device shown by the same applicant in European Patent Application EP-A-0 091 579.
  • the embossing wheel is positioned one after the other in such a way that the individual embossing element (type) is above the workpiece in the position to be embossed.
  • An anvil approaches the embossing element from its rear surface and presses the symbol present on the embossing element in mirror image into the material surface of the workpiece.
  • the characters to be embossed on embossing elements 2 are connected to a hub 4 of the embossing wheel by means of radial elastic spokes 3.
  • the embossing elements are guided in chambers 5 of the embossing wheel at least in the tangential direction.
  • the embossing element is mainly used during the braking process supported laterally so that it cannot move out of the position which is predetermined by the positioning of the embossing wheel.
  • the embossing elements 2 are cylindrical and the chambers 5 form corresponding hollow cylindrical recesses in which the embossing elements slide.
  • the hollow cylinders have a slight oversize, so that the types can be moved without significant friction.
  • the hollow cylindrical recesses of the chambers are open towards the bottom and lid and thus form passages for the character shape to be embossed or the plunger which presses down the embossing element.
  • the radially formed recesses 5 are followed by further radially directed recesses 6 which receive the spoke when the embossing element is depressed for embossing.
  • the spokes have an additional lateral guide and there is a space for actuating the types via the elastic spokes 3 radially inserted into them, which are firmly clamped at their other end to the hub 4 of the embossing wheel.
  • the spokes 3 are angled and open in one area 7 parallel to the axis of the embossing wheel. The ends of the angled ends of the spokes are inserted into bores 8 directed parallel to the axis of the embossing wheel.
  • the inner ends of the spokes are secured against sliding out and twisting by means of a tension disk 9 which presses the inner ends of the spokes against a radially directed stop surface 11 of the embossing wheel.
  • the tensioning disk maintains a distance from the stop surface which corresponds approximately to the spoke diameter, the tensioning disk being screwed to the hub of the embossing wheel.
  • the embossing wheel consists of a light metal such as aluminum or titanium, so that the inertial forces that occur are low. To further reduce the mass, the wheel has essentially circular recesses with a diameter, which leave webs between the edge supporting the chambers and the hub, which have sufficient strength and rigidity to form a rigid connection which prevents a deformation which impairs the setting accuracy.
  • the embossing wheel has a coating of titanium a few ⁇ thick.
  • An eccentric bore 12 in the vicinity of the central axial bore 13 serves for the angularly accurate transmission of the shaft position when the stamping wheel is positioned.
  • the embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different types.
