Definitions

  • the invention relates to a method and an apparatus of the genera specified in the preambles of claims 1 and 5.
  • embossing depth has scoring or groove depth z. B. is 0.2 mm.
  • embossing depth is practically impossible and the embossing devices commonly used not ensure that a given embossing depth is actually achieved and adhered to, methods and devices of the type described are required by means of which the embossing depth automatically determined and compliance with a preselected embossing depth are automatically ensured can.
  • the DE 20 2006 002 052 discloses an apparatus for marking a workpiece by creating a recess in a surface to create a recess by material deformation.

  • the technical problem underlying the invention is to further develop the method and the device of the generic types described at the beginning in such a way that a rapid determination taking place during the stamping process and with high accuracy is carried out the embossing depth is possible and thus incorrectly marked workpieces are largely avoided.
  • the invention has the advantage that the distance sensor, since it is moved together with the needle perpendicular and parallel to the workpiece surface, constantly indicates its distance from the workpiece surface during the embossing process, including one at the beginning of the embossing process and the rest of the embossing needle At the same time, the reference value determined on the workpiece surface supplies an exact measure of the current embossing depth. The closer the Abstandssenor is arranged on the embossing needle, the more accurate is the determined embossing depth, since in this way a possible deflection of the workpiece is neutralized. Finally, the influence of any wear of the embossing needle can be largely compensated by determining a new reference value before the generation of each character.
  • Fig. 1 shows a device in the form of an embossing unit 1 for producing markings according to the method of the so-called scratch marking.

  • a stamping or needle head 17 is fixed, in which an embossing needle 18 is movably mounted and parallel to the Z-axis of the imaginary coordinate system can be moved back and forth.
  • the embossing unit 1 described so far can be designed in such a way as corresponds to the general state of the art. Therefore, in particular, the stepping motors 8 and 11, as is common in the case of XY tables, can be rotated in rotation with control units, not shown, in such a way that the embossing needle 18 in the X and Y directions along the surface of an in Fig. 1 Unillustrated workpiece is moved to write one or more characters and form by a scratching operation in the workpiece surface. Since such controls are familiar to those skilled in the art, their detailed description is omitted.

  • a radially extending bracket 31 is fixed, which by a lateral recess 32 (FIG. Fig. 2 ) of the bottom part 25 protrudes to the outside.
  • a parallel to the embossing needle 18 extended distance sensor 33 is fixed, wherein the recess 32 is formed so that the holder 31 and thus the distance sensor 33 can join all occurring in the Z direction movements of the embossing needle 18.
  • the lower end of the distance sensor 33 has a distance A from the underside or tip 18a of the embossing needle 18, (FIG. Fig. 3 ) which is at least as large as corresponds to the desired embossing depth of the characters to be produced.
  • the distance A is also so much greater than the embossing depth, as corresponds to a tolierbaren wear of the embossing tip 18a in use. It is thereby achieved that the distance sensor 33 is always arranged above a workpiece surface and therefore does not touch it, even if the embossing needle 18 is pressed into the workpiece surface with the maximum embossing depth.

  • the sensor signals obtained in this way can be determined in the manner of a motion detector, whether the embossing unit 1 moves during a stamping phase in the X and / or Y-direction relative to the workpiece 34 or if no such relative movement takes place as required. If necessary, the embossing process can be interrupted and provided for a shift-free storage of the embossing unit 1 on the workpiece 34.
  • FIGS. 5 and 6 show how, by means of the distance sensor 33, an exact measurement of the embossing depth can be made if the surface 34a is marked by scratches with a mark 34b (FIG. Fig. 6 ) should be provided.
  • the embossing needle 18 is first characterized in that the piston 22 ( Fig. 3 ) is acted upon by the opening 23 through a first, relatively low pressure, advanced in the Z direction so far that it sits with its tip 18a on the surface 34a, without penetrating into it.

  • the final state obtained is in Fig. 5 in which the distance sensor 33 (or its underside facing the surface 34a) shows a first distance L1 from the workpiece surface 34a.
  • the pressure of the pressure medium introduced through the opening 23 is now increased so much that the tip 18a of the embossing needle 18 correspondingly Fig. 6 penetrates into the surface 34a to a desired embossing depth L3.
  • the difference L3 L1-L2 at each position of the image character 34b gives the current actual value of the embossing depth at. Consequently, it is possible according to the invention to not only permanently measure the current embossing depth L3 during an embossing process, but also to modify it, if necessary, by controlling the pressure acting on the piston 22. A provision of the embossing needle 18 in a direction away from the workpiece surface 34 a direction is effected in each case by the compression spring 30.
  • the control device includes a regulator 38, a connected thereto adjusting device 39, for example in the form of a pressure control valve, which in one with the opening 23 (FIG. Fig. 1 ) is connected and controls the pressure of the force acting on the piston 22 pressure medium, and acted upon by the actuator 39 embossing needle 18 which is fixedly connected to the distance sensor 33.

  • a particular advantage of the invention is therefore that the determination of the reference value L1 can be made anew before the embossing of each individual character.
  • the embossing needle 18 slightly wears during embossing of a character or the distance between the tip 18a and the bottom of the sensor 33 should have changed for some reason, the next character is still scribed with the predetermined embossing depth, since in this case the reference value L1 changes accordingly and the differential value formed in the setpoint generator 41 is adjusted accordingly. In this way, the embossing depth L3 at least as long as kept absolutely constant until the embossing needle 18 is worn to a no longer tolerable value.
  • a further advantage of the invention results from the fact that any deflections of the workpiece 34 are also included in the formation of the reference value L1. Namely, if the workpiece 34 is slightly deflected by the embossing needle 18 before it penetrates into the surface 34a, the reference value L1 required for the control does not change because the distance sensor 33 constantly participates in the movements of the embossing needle 18. Therefore, it is particularly advantageous if the distance sensor 33 as close as possible, d. H. as close as the installation conditions permit, is arranged next to the embossing needle 18. Any deformations of the workpiece 34 then have at most a negligible effect on the reference value L1.

  • the embossing unit 1 is supported by means of at least one support foot 49 on the workpiece surface 34a.
  • Relative displacements of the embossing unit 1 and of the workpiece 34 in the X and / or Y direction therefore result in a pivoting of the probe 45 in the ball joint 46.
  • This pivoting is by means of a z. B. inductively acting, the top of the probe 45 associated sensor 50 is scanned and used when exceeding the preselected tolerance range for switching off the embossing process.
  • the invention is not limited to the described embodiment, which could be modified in many ways. This applies in particular to the type and design of the various sensors.
  • the distance sensor 33 which is particularly preferably an inductively or according to the eddy current principle working sensor that provides analog or digital distance signals, for example, a capacitive or optical sensor could be provided.
  • a capacitive or optical sensor could be provided.
