Definitions

  • the invention relates to a method for the regeneration of painted and / or primed metal sheets, in particular for the regeneration of body-in-white of motor vehicles, in particular cars, and a device for carrying out the method.
  • the invention has for its object to provide a method and an apparatus for performing the method of the generic type, with which a regeneration of body shells or sheets is possible in a simple manner that have defects in the primer or paint.
  • the sheet coated with paint and / or primer or the body shell coated therewith be completely freed from the coating by means of water jet processing or that only the outer layer of the coating or several outer layers be completely removed by means of water jet processing, whereby the water jet processing is carried out with a high pressure of at least 1000 bar, preferably 1500 bar to over 2800 bar.
  • the water jet for the water jet processing is applied via water jet nozzles to the coated sheet metal or the coated body-in-white and the water jet nozzles are moved automatically so that the water jet nozzles are guided in a meandering manner over the surface or contour to be freed.
  • the kinetic energy of water jets is used to separate layers of lacquer and / or layers of primer from metal sheets or body shells.
  • the regeneration can include, for example, only the lacquer layer, so that only the lacquer layer or
  • Lacquer layers are removed or the corresponding sheet metal or the body-in-white can be freed of adhering layers apart from the base metal, sheet steel, aluminum sheet or the like become.
  • water is compressed with a high pressure pump and transported to the water jet nozzle. A free jet emerges from the nozzle
  • the method according to the invention can be used extremely cost-effectively and, as a result, leads to flawless basic products which can easily be primed and painted again.
  • the invention also relates to a device for carrying out the method according to one of claims 1 or 2, which is characterized in that that the device consists of a cabin with side walls, roof wall and end walls, the end walls being closable
  • Passage openings have that the cabin is penetrated by a longitudinal conveyor arranged on the bottom, on which a bodyshell to be cleared of paint layers can be transported, which can be moved through the passage openings into the cabin or out of the cabin, that running rails are arranged parallel to the longitudinal conveyor, preferably next to it on both sides are, on which programmable robot units can be moved, which have a high-pressure water supply and at the mouth of which water jet nozzles are directed, the jet of which is directed toward the surface of the body-in-white to be cleared of paint layers, the nozzles being meandered over the surface.
  • the floor of the cabin is formed by a grate, in particular a grating, at least in the passage area of the body-in-white, primarily in the entire area of the longitudinal conveyor and robot arrangement, below which a particle / water collecting chamber with a particle separator and / or filter is arranged .
  • High pressure water lines are fed by plunger pumps or similar hydraulic cylinders.
  • a transverse conveyor with a lifting station is arranged which is directed transversely to the longitudinal conveyor, by means of which a

  • the device shown in the drawing is used to regenerate painted car bodies 1 of motor vehicles.
  • the varnish and optionally also the primer of the body-in-white is completely removed by means of water jet processing, so that the base plate of the body-in-white is bare and can be properly primed and painted again.
  • surface treatment of the body-in-white is carried out at a pressure of 1500 bar to 2800 bar with appropriate nozzles in order to remove the corresponding layers.
  • the device consists of a cabin 2 with side walls 3, roof wall 4 and end walls 5.
  • the end walls have closable passage openings 6 which can be opened or closed by means of automatic sliding doors 7 or the like.
  • the cabin 2 is penetrated by a longitudinal conveyor 8 arranged on the bottom, on which a carriage 9 is arranged, which can carry a body-in-white 1.
  • the body shell 1 can thus be transported through the cabin 2 in the direction of the arrow 10.

Abstract

L'invention concerne un procédé de régénération de tôles vernies et/ou enduites d'une couche de fond, en particulier pour la régénération de carrosseries brutes de véhicules, notamment de voitures particulières, et a pour but d'effectuer de manière simple une régénération de carrosseries ou de tôles présentant des défauts dans la couche de fond ou dans le vernis. A cet effet, l'invention est caractérisée en ce que la tôle enduite d'un vernis ou d'une couche de fond, ou la carrosserie ainsi enduite, est débarrassée totalement du revêtement par traitement au jet d'eau, ou bien uniquement la couche extérieure du revêtement, ou plusieurs couches extérieures, sont complètement enlevées par traitement au jet d'eau, et en ce que le traitement au jet d'eau s'effectue sous haute pression, d'au moins 1000 bar, de préférence entre 1500 bar jusqu'à plus de 2800 bar.
