Definitions

  • the invention is based on a hand tool according to the type of the main claim. It is known to use angle grinders for deburring and plastering the edges of sheets welded one above the other and the welding points in the vicinity of these edges.
  • the main patent (patent application P 34 04 036.6) also relates to such a hand tool. With these hand-held power tools, the work is relatively dangerous for the operator, because he can slip easily and cut injuries on the sharp edges, unless relatively expensive automatic handling machines are used for this.
  • the hand tool according to the invention with the characteristic. Drawing features of the main claim has the advantage that the operator is protected from cuts and still work can be carried out more economically.
  • the hand-held power tool With the wires of two metal wire brushes facing one another and arranged at an angle to one another, the hand-held power tool can be supported and safely guided on the sheet edge to be deburred. Due to the resilient yielding of the wires, preferably as a pot. B crushed metal wire brushes ensures the simultaneous processing of both sheet metal edges and the welds on both sheet metal surfaces near the edges, without the need for special manual skills. Different sheet thicknesses or slight tilting of the hand machine tool also have no effect on the effect of the deburring brushes. Damage to the sheet metal parts in the processing area is excluded.
  • the metal wire brushes also have a long service life and are relatively inexpensive to manufacture. The manufacturing tolerances to be observed can be set generously.
  • the stop ring mounted between the brushes prevents the brushes from being driven too far into the sheet metal surfaces and, for example, scratching the surfaces to be painted.
  • FIG. 1 An embodiment of the subject of the invention is shown in the drawing and explained in more detail in the following description.
  • the single figure shows a hand tool according to the invention in a side view, partially in section.
  • An angle grinder 1 has a work spindle 2 on which two metal wire brushes designed as cup brushes 3 and 4 and placed opposite one another are fastened.
  • cup brushes are pushed onto the work spindle 2 and held at a predetermined distance from one another by means of a spacer sleeve 5.
  • the rear end face of the pot brush 4 lies against a collar 6 of the work spindle 2.
  • This cup brush 4 must therefore first be pushed onto the work spindle 2.
  • the spacer sleeve 5 is pushed onto the work spindle 2. It bears a stop ring 8 on a ball bearing 7.
  • the stop ring has a groove 9 running in the circumferential direction.
  • the bearing of the stop ring 8 on the spacer sleeve 5 is selected such that it comes to lie exactly in the middle between the two cup brushes 3 and 4.
