Definitions

  • the invention relates to a manufacturing method for producing a Lackieranlagenbauteils, in particular for the production of a component of a color changer, a paint valve, a sprayer, a robot or the like. Furthermore, the invention relates to a correspondingly manufactured Lackieranlagenbauteil.
  • a disadvantage of these known production methods is the limited design freedom in the shaping, since certain component shapes can not be realized with the respective production methods.
  • through-feeds for media eg dishwashing liquid, paint, air
  • bores which, however, can only have a straight course as a result of the production, so that changes in the direction of the passages are always associated with a kink at which turbulence can occur.
  • the usual manufacturing processes in the paint shop components lead to undercuts and dead spaces, which in turn cause pressure losses and affect the Spülbar- speed.
  • Another disadvantage of the known manufacturing method for Lackieranlagenbaumaschineer is that the production of a pattern during the development process is relatively expensive and takes a lot of time.
  • the invention has the object to provide correspondingly improved Lackieranlagenbaumaschine.
  • pid-prototyping process In contrast to conventional machining processes (eg milling, drilling), pid-prototyping process not to material-removing production processes, but to material-building manufacturing processes.
  • a difference between rapid prototyping methods and the aforementioned molding methods is the lack of a predetermined shape, so that individual component forms can be realized.
  • SLS selective laser sintering
  • a polyamide casting process can be used, which works with polyamide as a material.
  • the use of a rapid prototyping method has not yet been proposed for the production of Lackieranlagenbau former, since the known rapid prototyping method only allow an unsatisfactory surface roughness, which is not acceptable for Lackieranlagenbaumaschine, since in media-carrying Lackieranlagenbau former a lower surface roughness is required to achieve a good rinsability in a color change or work interruptions.
  • the paint shop component produced by the rapid prototyping method is therefore preferably subjected to surface-smoothing finishing after the rapid prototyping process has been carried out, in order to achieve the desired low surface roughness.
  • the surface-smoothing post-processing of the painting installation component may be effected by an electrochemical treatment, polishing, in particular electropolishing, pickling, grinding, honing, lapping, shot peening, dry ice blasting, dry snow or sizing.
  • polishing in particular electropolishing, pickling, grinding, honing, lapping, shot peening, dry ice blasting, dry snow or sizing.
  • media eg paint, detergent, air
  • paint can adhere to rough inner walls of passages, which is particularly disturbing in a color change.
  • a pressure loss occurs along the passages, since the smallest possible line cross-sections are preferred.
  • Such passages can be smoothed by passing particles through the passageway, which particles can be suspended in a carrier liquid or contained in a carrier gas.
  • the particles then act abrasive on the inner wall of the passage and thereby lead to a surface smoothing.
  • the particles may be granules, beads, spheres, moldings or dusts of glass, ceramics, alumina, polymers, nutshells, organic substances, CO 2 pellets, snow, sand or minerals.
  • the type, shape and size of the particles are selected according to the passage cross section and the desired surface quality.
  • the painting component made of plastic produced according to the invention may comprise existing parts and parts made of metal, which are preferably both formed in the context of the rapid prototyping method.
  • a metal valve seat seamless be inserted into a polymer matrix.
  • the Seal of components is used.
  • components of color changers or metering pumps with the production method according to the invention.
  • the production process according to the invention is also suitable for producing miniaturized models of paint shop components, for example models of robots, in particular painting robots or handling robots, paint booths, painting lines, paint shops or atomizers, to name just a few examples.
  • the paint shop component produced according to the invention is substantially dead space-free and / or essentially free of undercuts in order to achieve a good flushability.
  • undercuts can easily be produced.
  • connection thread for the hoses in the center of the component can be arranged because of the twisting and laying by the hand axis. Thereafter, the channel is routed close to the outer wall of the component to provide space inside for functional components (e.g., valves).
  • FIG. 3 shows a production device according to the invention with a rapid prototyping machine
  • first step S3.1 a first layer of a first material A is first applied.
  • the layered material A is then partially solidified according to the given design or control data of the Lackieranlagenbauteils at certain component sites.
  • the non-solidified residues of the material A are then removed by suction.
  • a layer of a second material B is then applied and then partially solidified in step S3.5 in accordance with the predetermined control or design data at specific component locations.
  • the non-solidified residues of the material B are then removed by suction in step S3.6.
  • the steps S3.1- S3-6 are then repeated for each layer of material until the desired Lackieranlagenbauteil is formed.

  • Figure 6A shows a conventional rotary atomizer 14, as described for example in DE 102 33 198 Al, so that the content of this patent application of the present description in terms of the structure and operation of the rotary atomizer 14 is fully attributable.
  • FIG. 6B shows a rotary atomizer 14 according to the invention, which, except for the differences mentioned below, completely coincides with the rotary atomizer described above and shown in FIG. 6A, so that reference is made to the above description to avoid repetition, the same reference numerals being used for corresponding details become.
