Definitions

  • the invention relates to a coating method for mass parts as bulk goods according to the preamble of claim 1.
  • mass parts made of steel, for example in the form of Bolts, nails and screws etc., as bulk goods with a coating, for example made of zinc, of different thicknesses.
  • this coating can which are placed on the finished product by processes such as galvanizing, mechanical plating, hot dip galvanizing, etc.
  • No. 5,393,346 describes a coating method for bulk parts as bulk material is known in which on the bulk material located in a rotating drum liquid coating is sprayed onto the bulk material through an opening in the drum. The liquid coating is then heated by the bulk material dried, so that a film forms on the individual parts in the drum, which also is not excessively thick in the recesses of these parts.
  • the invention has for its object an environmentally friendly and inexpensive To develop coating processes for the coating of bulk parts as bulk goods, in which no harmful hydrogen entry into the individual parts of the bulk material he follows.
  • the bulk material is continuously turned with the help of the rotating drum kept in motion so that the individual parts of the bulk material are never for one Touch for a longer period in the same place.
  • the coating material is from provided in a coating system arranged outside the drum heated and atomized under high pressure and thereby onto the bulk material spun.
  • the coating material is applied at a rate of, for example 30 m / sec to 650 m / sec hurled onto the bulk material.
  • spray duration melting rate set can be. Heating causes the coating material to melt brought.
  • the coating material is a fusible material that is wire-shaped - for example zinc wire - or powdered - for example zinc powder, metal alloys, plastic or Ceramics - available.
  • a strong cooling of the heated and atomized coating material due to a large distance between the bulk material and that area of the coating system, in which the coating material is atomized, for example can be prevented by expediently heating the coating material with a spray gun of the coating system arranged close to the bulk material.
  • the surface of the bulk material is roughened and activated by means of a blasting process. This Roughening and activation of the surface of the bulk material contributes to better adhesion of the coating material that is applied to the bulk material during coating becomes.
  • the bulk material is expediently blasted outside the Drum, for example in a compressed air, sandblasting or centrifugal wheel system at fine-grained blasting medium is thrown onto the bulk material at high speed, roughened.
  • the bulk material has, for example, a surface roughness after the blasting process from RZ 16-20 ⁇ m.
  • the applied coating is relatively rough. If necessary, preferably the surface of the bulk material in a process step following the coating to be smoothed. The roughness typical of the process is leveled and the Layer compacted so that the properties of the coating in terms of appearance and Corrosion behavior can be improved.
  • Particularly high coating qualities can be achieved by smoothing the bulk material advantageously outside the drum in a smoothing device with at least an additional aid.
  • the tool is, for example around small polished steel balls with a diameter of, for example, 0.3 mm to 5 mm.
  • the container of the tumble mixer can, for example, rotate during the smoothing process or tumble. But it can also be cylindrical and with a conveyor spiral be equipped with the bulk material to be smoothed and the tool for smoothing one filling-side, first end transported to an ejection-side, second end of the container.
  • the bulk material 5 in which it is for example pin-shaped elements such as nails are roughened.
  • This blasting process does not result only clean surfaces, but also roughen them, so that the following Coating applied coating can adhere particularly well.
  • Method step B relates to coating, in which, for example, a Corrosion protection serving, heated and atomized coating material on the Surface of the bulk material is thrown.
  • FIG. 2 there is the bulk material 5 - a large one Number of nails - in a rotating drum 1.
  • a rotation axis 12 of the Drum 1 is arranged at an angle W of 25 ° with respect to a horizontal.
  • the drum 1 is connected to a drive shaft 2 of a drive device 3, which extends coaxially to the axis of rotation of the drum 1.
  • the drum 1 At a first, front end 10, the drum 1 has an opening 4 which the Feeding the bulk material 5 into the drum 1 and removing the bulk material 5 the drum 1 is used. A second, opposite the first end 10, the front end 11 of the drum 1 is fixed to the drive shaft 2 of the drive device 3 connected.
  • the drum 1 is made of a perforated plate, which is not Holes shown in more detail, for example, have a diameter of approximately 2 mm. The The distance between the holes is also approx. 2 mm.
  • the drum 1 is composed of two conical sections of different sizes together, with a larger section with respect to the length of the drum 1 in Tapered towards drive device 3.
  • a smaller section tapers to first, end 10 of the drum 1 and is of a large clear width having, opening 4 limited.
  • the drum 1 is designed such that it is also, but only partially tapered towards the first, front end 10. The clear expanse of the Opening 4 at the first end face is somewhat reduced.
  • a good loading of the drum with the bulk material or a good removal of the Bulk from the drum is achieved by preferably rotating the drum axis at an angle of 1 ° to 90 °, in particular between 20 ° and 30 ° a horizontal is arranged.
  • the bulk material 5 located in a receiving chamber 9 of the drum 1 is located in constant motion during coating.
  • the spray gun 6 is part of a Coating system 8. Inside the spray gun 6 is the coating material heated and atomized under high pressure and onto the bulk material to be coated spun.
  • the spray gun 6 is - depending on the inclination of the drum 1 and Size of the opening 4 in the drum 1 - just outside the drum 1 in front of the Opening 4 arranged or projects into this opening 4, for example.
  • the coating system 8 is not supported on one represented surface of a substrate. With a handling system, the Spray gun 6 are moved during coating.
  • FIG. 1 shows a further process step C - the smoothing - that of the second process step B - the coating - can be downstream.
  • the applied Coating material ensures a rough surface on the individual parts of the Bulk material 5. This surface is after coating in a not shown Smoothing device smoothed and compressed. This helps to improve the layer properties and the optical appearance of the same.
  • the smoothing is done outside the drum 1 in a container of the smoothing device together with one not tools shown in the form of polished steel balls. The container leads during the smoothing process for example, a rotating or tumbling movement.
  • the shown in Fig. 1 Process steps A, B and C can be integrated into one or two Plants are carried out. Process steps B and C can also be carried out simultaneously or alternately.
