Definitions

  • the invention relates to a device for matting a surface according to the preamble of claim 1. Furthermore, the invention relates to a method for matting a surface with such a device.
  • Devices for matting glossy surfaces of a vehicle and / or a vehicle component are known in numerous variations. These known devices for matting painted surfaces have approximately cuboid jet nozzles or jet chambers. Here, a blasting agent beam is directed approximately perpendicular or at an angle significantly above 60 ° to the surface to be irradiated. A flat matting of the surface is achieved by a relative movement between the workpiece and the nozzle.
  • a method for processing a glossy surface of a vehicle and / or a vehicle component is known, which is painted with a clearcoat layer of a given first layer thickness.
  • a blasting medium is metered into a carrier air flow generated by negative pressure, conveyed in a hose line system to a jet lance and directed to a set by a blasting chamber under vacuum processing surface, then transported back into the air flow, cleaned and optionally circulated.
  • the acceleration of the blasting agent is generated by the negative pressure and the blasting chamber on the processing surface, wherein the blasting agent at least one additional energy pulse through at least one further sucked by the vacuum, at least at atmospheric pressure gas flow to Achieving a lying well above the flow velocity of the carrier air flow end velocity upstream of a dosing is granted.
  • the final velocity is used to set an energy input into the processing surface as a function of the type and shape of the processing surface and of the blasting medium, degree of carrier air stream loading, blasting medium carrier pressure, blasting time and blasting temperature, so that approximately 1 to 50 percent of the given first layer thickness of the clearcoat layer is removed is, whereby the surface of the vehicle and / or the vehicle component is frosted and forms a reduced second layer thickness of the clearcoat film.
  • a generic device for matting surfaces is described.
  • a disadvantage can be considered in the known apparatus and methods for matting a surface, the long duration of the matting process for larger surfaces to be matted, since the area performance of matting results from the relative speed between the workpiece and nozzle or blasting chamber.
  • the invention is based on the object to provide a device and a method for matting a surface, which allow a higher area performance of matting.
  • the workpiece and nozzle remain rigidly to each other during the irradiation process, wherein a direction of a abrasive jet of abrasive material within a Beam chamber in approximately parallel or at an angle less than 30 ° to the interaction opening and the surface to be matted is aligned.
  • a device for matting a surface is understood below to mean an assembly having a nozzle which has the blasting chamber for irradiating a workpiece with an abrasive radiation material.
  • the blasting chamber has at least one planar interaction opening on at least one of its sides, which is intended to be placed in a form-fitting manner on at least one surface to be matted, so that the blasting chamber is thereby closed.
  • a method for matting a surface with such a device comprises the following steps: providing a workpiece with a surface to be matted, placing the device with its planar interaction opening on the area of the surface to be matted, and irradiating the surface with a blasting medium beam of abrasive material in a first beam direction.
  • the abrasive jet of abrasive material is aligned approximately parallel or at an angle less than 30 ° to the interaction opening and the surface to be matted.
  • Embodiments of the invention enable a significantly higher area performance with otherwise identical beam parameters due to a "surface-shaped blasting". This means that at the same time the entire surface to be frosted is irradiated, whereby the blasting material can hit the workpiece several times. Since the workpiece and the nozzle during the irradiation process remain rigid to each other, and the surface performance of matting is determined by the relative speed between the workpiece and the particles of the abrasive material and not by the relative speed between the workpiece and blasting chamber or nozzle, resulting in a much higher Area performance than in the known from the prior art methods and devices. For example, glass breakage or particles of glass with a size of, for example, 150 ⁇ m can be used as the radiation means become. By specifying irradiation time, particle size, particle velocity, material, etc., different matting effects can be achieved.
  • the surfaces to be matted in embodiments of the invention are roughened grooved, so that no craters arise as in a beam angle with a steeper angle than 60 ° aligned.
  • the groove-like roughening of the surface results in a more homogeneous matting on the micro level than in the beam medium beam aligned at a steeper angle than 60 °.
  • the matt surfaces produced are homogeneous.
  • aggressive media can run better through the groove-shaped structure or drain. Overall, a higher chemical resistance of the matting produced results in an advantageous manner.
  • the component handling can be made very ergonomic. Since no moving parts of the system are present, the method according to the invention is very safe.
  • a relative speed between the particles of the abrasive material of the blasting agent jet and the surface to be matted can determine a surface power of the irradiation process.
  • a negative pressure generated in the blasting chamber can connect the at least one interaction opening in a fluid-tight manner to the at least one surface to be matted. Due to the generated negative pressure, a good connection between the at least one surface to be matted and the blasting chamber can be produced in a simple manner. In addition, the safety of the method can be increased, in that starting the blasting process is prevented when the workpiece is not properly connected to the nozzle and no negative pressure can be generated in the blasting chamber.
  • the blasting chamber can have at least one interaction opening at least on an upper side and on an underside, which can each be covered by a surface to be matted.
  • the irradiation can be carried out with high efficiency and without wear of a wall of the blasting chamber or blasting nozzle.
  • a plurality of interaction openings can be formed on the at least one side of the blasting chamber, which can each be covered by a surface to be matted. As a result, several small surfaces or workpieces can be matted at the same time.
  • the jet direction of the abrasive jet of abrasive material can be reversed.
  • the result of the matting can be further improved.
  • a nozzle contour which encloses the at least one interaction opening, be formed as a fixed support frame with a seal on which rests the workpiece with the surface to be matted.
  • the nozzle contour can be formed as a flexible edge with a seal which adapts to a contour of the workpiece in the region of the surface to be matted.
  • the irradiation of the surface can be carried out with a jet stream of abrasive material in a second beam direction, which runs approximately opposite to the first beam direction. Furthermore, the alternate irradiation of the surface with the abrasive jet of abrasive material may be repeated until a desired degree of matting of the surface to be matted is achieved.
