Definitions

  • the invention relates to a pretreatment plant for the pretreatment of surfaces to be painted by Maschinenstükken, in particular motor vehicle bodies or body parts, with at least one cabin in which the workpieces are exposed to chemicals during the pretreatment, wherein the cabin is composed of a plurality of cabin elements.
  • the invention relates to a method for producing a pretreatment plant for the pretreatment of surfaces to be painted of workpieces, in particular of motor vehicle bodies or body parts, wherein at least one cabin in which the workpieces are exposed to chemicals during the pretreatment is composed of a plurality of cabin elements ,
  • Pre-treatment plants are used for the pretreatment of surfaces to be painted of motor vehicle bodies or body parts.
  • the motor vehicle bodies or body parts are first treated in the course of the pretreatment process for degreasing with lyes or similar fat-dissolving substances and then for the subsequent painting with acids, in particular Phosphoric acid in zinc phosphating or hexafluorozirconic acid during passivation, prepared.
  • the treatment may consist in spraying and / or diving.
  • Spraying pretreatment plants include, for example, a tunnel-shaped cabin, which is composed of a plurality of, depending on the workpiece, up to 5 m high walk-in cabin modules, in which spraying devices are arranged in particular for spraying alkalis, acids and water.
  • the cabin modules in turn are composed of a plurality of cabin elements.
  • the cabin elements are made of stainless steel.
  • functional parts in particular the spray devices, preferably jet or spray rings, and spray covers, are fastened to the cabin walls.
  • the cabin is tight, so that no lye or acid can escape from them.
  • High demands are placed on the connection of the cabin elements and the cabin modules and the fastening of the functional parts. So they have to withstand the aggressive chemicals used in the pretreatment plant. In addition, they must withstand high mechanical loads due to the relatively large and correspondingly heavy cabin elements and functional parts. So far, therefore, the cabin elements are welded tight together.
  • the functional parts are attached (welded) or bolted to the cabin walls.
  • Object of the present invention is to make a pre-treatment plant of the type mentioned and a method for producing such, in which / the cabin elements are technically simple and permanently connected to each other, wherein the assembled pretreatment plant has substantially without reworking a visually appealing appearance ,

  • the sealing / adhesive may have a high strength, in particular the ability to a large gap bridging, preferably of up to 10 mm. In this way, gaps between adjacent cabin elements, which arise, for example due to manufacturing tolerances in particular for large cabin elements, with the sealing / adhesive be bridged. This is not possible, for example, with epoxy and acrylate adhesives because they have too low elasticity and the ability to gap bridging less than 1 mm.
  • the adhesive may also have high strength, in particular the ability to have a large gap bridging, preferably of up to 3 mm.
  • the sealant / adhesive and / or the adhesive may be resistant to acids, especially to phosphoric acid in zinc phosphating baths and / or hexafluorozirconic acid, and alkalis. This has the advantage that the adhesive joints are permanently tight.
  • the sealant / adhesive can cure in at most about 24 hours. This advantageously allows working without time pressure.
  • the adhesive can cure quickly, especially in a maximum of 15 minutes.

  • the two-component Acrylic Double Performance and Activated Double Bond Adhesive also exhibits the above sealant / adhesive properties and cures quickly. He also has a high strength, so that the adhered functional parts are kept stable.
  • the cabin may be composed of a plurality of cabin modules, which in turn are composed of a plurality of cabin elements. This has the advantage that the cabin modules are prefabricated at the factory and are easy to transport to the place of installation, where they are assembled to the cabin.
  • the inventive method is characterized by the fact that the cabin elements are technically easily connected with a sealing / adhesive.
  • sealants / adhesives for connecting the cabin elements, no deformations or discoloration of the surfaces of the cabin elements arise, so that expensive finishing, in particular for restoring the tightness and the appealing visual impression, can be dispensed with.
