Definitions

  • Cleaning methods and devices are known in various embodiments from the prior art.
  • such methods and apparatus are used for the cleaning of welds in metal components.
  • a concentrated jet of accelerated abrasive particles is directed onto the area to be cleaned.
  • such a jet is guided along the weld to be cleaned, specifically a region around the weld being processed. In this method, therefore, only a limited area of the metal component is treated, while the remaining part of the machined metal component is not or only very unevenly charged with Strahlgutpellen.
  • the directed particle beam must often be above the metal component be moved, which is time consuming and often does not lead to a uniform beam result.
  • no uniform surface compaction can be achieved by means of such a method.
  • ceramic jet particles can not be used as blasting material in most of the devices of the prior art, since the particular hardness of these particles leads to too rapid wear of these devices and thereby make the process uneconomical.
  • the invention has for its object to provide a device for efficient implementation of the method to clean a metal component in a simple manner particularly time efficient and at the same time to achieve a full-surface compaction.
  • the method for surface compaction and cleaning of a metal component comprises first supplying the metal component to a processing area, followed by treatment of the metal component with a grit in the processing area and subsequent removal of grit particles from the metal component, wherein the grit of ceramic particles and the treatment of the metal component takes place substantially on all sides and over the entire surface.
  • the method advantageously makes it possible to clean and refine metal components, in particular those comprising a plurality of metal elements welded to one another, in a particularly simple and time-efficient manner. This is possible because the metal component is acted upon at the same time from all sides with blasting material and therefore a systematic shutdown of the surface with a direction Strahlgutstrahl, which is time consuming and usually does not lead to a uniform result is not necessary.
  • the entire surface is cleaned, but it also comes to a surface compression of the entire component, whereby the material properties of the workpiece are advantageously improved without separate processing step. This is possible in particular by the use of ceramic particles as blasting material.
