Definitions

  • the invention relates to a method for covering inner walls of a cavity of a vehicle body (10) or an attachment for a vehicle body with a protective layer of anti-corrosion wax according to the preamble of claim 1.
  • the invention further relates to a system for carrying out the method according to the preamble of claim 1.
  • Generic methods are used in vehicle construction to protect cavities of bodies and their attachments such as flaps, doors and the like against environmental influences. Typically, this is done by either applying corrosion protection wax to the surfaces concerned by spraying or by flooding the cavities with anticorrosion wax and then removing excess protective wax to cover the surfaces concerned.
  • the object of the invention is to provide a technically uncomplicated method and a system provided for this purpose, by means of which, with a low protective wax insert, a reliable covering of inner surfaces of a cavity is possible.
  • Corrosion protection wax is brought into a misted form (protective wax mist) by means of a mist generator and fed through an outlet opening to the cavity to be preserved.
  • the mist generator generates the protective wax mist by mixing pressurized protective wax and pressurized air.
  • the droplets of the protective wax mist emerge from the outlet opening at a speed ⁇ 10 m / sec.
  • the protective wax mist is deposited on the inner walls of the cavity and forms here a corrosion protection wax layer.
  • a mist atmosphere of protective wax and gas is generated or such a mist atmosphere is supplied to the cavity.
  • This consists of gas, especially air, as well as the finest droplets of corrosion protection wax. These are sufficiently small atomized to be hoverable in the surrounding air.
  • the mean droplet size of the droplets of the corrosion protection wax in the mist is preferably ⁇ 120 .mu.m, in particular preferably ⁇ 80 .mu.m or even ⁇ 60 .mu.m, on average for this purpose.
  • the production of such a protective wax mist takes place by means of a suitable mist generator.
  • the fog atmosphere of the protective wax mist which is introduced according to the invention for the purpose of surface coating in the cavity, unlike spraying the anti-corrosion wax does not directly on the walls of the cavity down, but spreads in the cavity and is also reflected in surfaces starting from the exit opening would not be directly accessible by spraying.
  • the type of precipitation of the protective wax and the layer formation can be influenced. Furthermore, it is also possible by electrostatic charging of the wax before or during the discharge and / or charge of the walls to influence the precipitation.
  • the solidification can be effected by an elevated temperature and a reduced temperature of the protective wax.
  • chemical drying, radiation drying or drying by air flow is also possible.
  • the protective wax mist can remain in the cavity at the completion of the process or be sucked out of it.
  • corrosion protection wax to be used for cavity preservation in vehicles already commonly used for spraying or flooding waxes come into question.
  • the droplets of the protective wax mist can exit from the outlet opening at a speed ⁇ 5 m / sec, preferably ⁇ 2 m / sec, in particular preferably ⁇ 0.5 m / sec.
  • the developing fog atmosphere in a targeted manner in motion.
  • This can be controlled by the speed and exit direction of the exiting protective wax mist.
  • the control of this movement by otherwise supplied energy is possible.
  • the supply of the protective wax mist can take place at several points or at changing points within the cavity to be preserved.
  • the supply of the protective wax mist can also be effected by means of several mist generators, which are arranged at different locations within the cavity to be preserved and / or are arranged in different directions relative to the cavity to be preserved.
  • the introduction of the protective wax mist at only one point of the cavity may be sufficient, since the protective wax mist is distributed in the cavity, a particularly good and rapid distribution of the mist can be promoted by said additional measures.
  • the mist atmosphere can be created from both ends.
  • a movable within the cavity outlet opening which discharges at different locations, with only one outlet opening a fairly homogeneous fog atmosphere can be created.
  • a plurality of outlet openings which point in different directions, it is particularly well ensured, in particular in conjunction with a common movement of these outlet openings through the cavity, that the mist atmosphere also reaches hard-to-reach surface areas.
  • the protective wax mist By generating a pressure difference between two offending portions of the cavity, the protective wax mist can be moved within the cavity.
  • the protective wax mist By alternately generating an overpressure and a negative pressure in at least a partial area of the cavity, a periodically repeated movement of the protective mist in the cavity can be produced.
  • the protective wax mist is distributed basically independently in the cavity largely homogeneous. However, since short cycle times are desired depending on the application, it may be particularly advantageous to selectively move the protective wax mist through a local overpressure or negative pressure in the cavity. This can be done, for example, by the introduction or suction of air at an opening of the cavity, either by a separate from the outlet pressure opening of the cavity preservation system or through the outlet opening itself. By periodically repeated increases or decreases pressure can also cyclic movement of the protective wax mist be generated in the cavity through which a particularly favorable precipitation behavior of the protective wax is achieved on the surface.
  • a typical workpiece, which is protected against corrosion by the methods according to the invention, is the partial area of a body with an elongate cavity. In such a case, it is possible to allow the protective mist to escape through the outlet opening in alignment with the main extension direction of the cavity.
  • the protective mist can also escape in a direction out of the outlet opening, which is angled relative to the main extension direction of such a cavity.
  • a similar effect can be achieved by providing an influence after exiting the mist through the outlet opening.
  • the protective wax mist can be selectively influenced after leaving the outlet opening with regard to its direction of movement, in particular by supplying air from different air nozzles from the outlet opening. By their mutually angled orientation these air nozzles are also able to effect such a helical movement of the mist atmosphere.
  • Fog nozzles are already known from other areas of the prior art.
  • a mixture of protective wax and air which are each pressurized, takes place before the protective wax mist emerges.
  • the pressurized air ruptures the liquid supplied protective wax and thereby generates the mist.
  • mist generators and outlet openings may additionally be provided that they have a rotatable component, so that the outlet openings is during the exit of the protective wax in a rotational movement, which serves the homogeneous distribution of the protective wax.
  • the outlet opening may be connected upstream of a mist production chamber.
  • the mist generator may be configured to generate the protective wax mist in the mist production chamber. It may be provided for conveying the protective wax mist to the outlet conveyor.
  • the upstream mist production chamber serves to generate a homogeneous mist even before introduction into the cavity to be preserved.
  • a conveyor such as a pump to promote the protective wax mist or to generate an overpressure in the mist production chamber, this mist is supplied in the homogenized form of the cavity.
  • the method may find application for supplying the protective wax mist into a cavity between walls of a double-walled hollow body. It can also find application for supplying the protective wax mist in a cavity whose inner walls are covered at least in sections by other wall sections, starting from the positioning of the outlet opening within the cavity. Even surfaces of curved or angled cavities are to be provided by means of the described method advantageously with protective wax. In particular, in such designs can be achieved by the protective wax mist better results than by spraying the protective wax.
  • the system has a working position at which a workpiece with a cavity to be preserved can be positioned. It has a supply device for supplying a corrosion protection wax in the cavity.
  • the supply device has a mist generator with outlet opening which can be positioned on or in the cavity to be preserved in such a way that the corrosion protection wax can be introduced into the cavity in atomised form (protective wax mist).
  • the plant has air nozzles for introducing air for the purpose of moving the generated protective wax mist inside the cavity.
  • the system may have at least one pressure generator, by means of which in a partial region of the cavity a negative pressure or an overpressure can be generated.
  • the pressure generator may be provided with a control device, is generated by the periodically changing pressure within the cavity.
  • system may have further to the described method as well as in connection with the embodiments mentioned components.
  • FIG. 1 and 2 show an exemplary workpiece 10, which may be, for example, a portion of a sill of a motor vehicle. It puts FIG. 1 a cut and FIG. 2 a perspective, sectional view. As can be seen, a cavity 12 of this sill is limited not only by a cylindrical outer wall 20, but also by partition plates 22.
  • the aim of the method described here is to cover the surfaces within the cavity with corrosion protection wax.
  • the mentioned bulkhead plates 22, however, make it impossible, starting From a front side region 14 of the cavity 12 by spraying corrosion wax to reach all surfaces.
  • FIG. 3 shows how in the method according to the invention, an applicator 30 is introduced with a nozzle, not shown in the figure with outlet opening 32 end in the cavity 12. Through the outlet opening 32 of the applicator then the protective wax mist 40 is introduced into the cavity 12.
  • the protective wax mist 40 consists of fine wax droplets with a mean diameter of less than 120 microns.
  • the protective wax mist 40 is distributed within the cavity 12 and is deposited on the surfaces of the outer wall 20 and the partition plates 22 down.
  • FIG. 4 shows the cavity with a protective wax layer 50, which has deposited on the walls.
  • a protective wax layer 50 in areas 52 which would not have been reachable directly from the outlet opening 32 by spraying, but only by the tendency of the protective wax mist 40 to homogeneously distribute in the cavity 12 and precipitate on the surfaces.
  • FIG. 5 shows again, similar to the FIG. 3 , the introduction of corrosion protection wax in the cavity.
  • the peculiarity lies in the fact that in the manner illustrated by the arrow 2, the outlet opening 32 is displaced within the cavity.
  • an even more homogeneous distribution of the mist can be effected.
  • the required time can be shortened, which it takes until the mist has been homogeneously distributed. This serves to achieve short cycle times.
  • each pressure channels 70, 72 are connected. These make it possible to specifically create an overpressure or a negative pressure in the areas 14, 16. In this way, in turn, the cloud of mist 40 can be selectively moved back and forth within the cavity 12, as is illustrated by the arrow 4a, 4b. In particular, the complete coverage of the bulkhead plates 22 with corrosion protection wax is thereby promoted.
  • FIG. 7 shows a design in which in addition to the applicator 30 two air nozzles 60 are inserted in the end region of the cavity, said air nozzles each define an exit direction of the air, which is not only in the main extension direction 1 of the cavity 12, but in contrast both clockwise or both against are angled in the clockwise direction. hereby can be a helical twist in the mist 40 generate, which causes a kind of screwing the fog into the cavity and thereby in turn favors the coverage of difficult access surfaces.
  • FIG. 8 shows that similar can also be achieved in that the mist generator itself has two outlet openings 32a, 32b, which are angled in opposite directions in order to produce the desired spin can.
  • the applicator 30 can rotate as a whole.
  • FIG. 9 shows a clear difference.
  • a mist-generating chamber 80 belonging to the plant and not to the workpiece is provided, into which the protective wax mist 40 is produced by means of a mist nozzle 31. From here, the mist is fed through a channel 90 to the actual cavity. This can be done via a pump 92 or, for example, by causing, in addition to the protective wax mist 40 via a separate channel, an overpressure in the mist production chamber 80, which pushes the protective wax mist 40 through the channel 90 into the workpiece.
