Definitions

  • the deburring tool according to the invention has a grinding belt holder which is designed to hold a grinding belt, the deburring tool comprising a housing in which the grinding belt holder can alternately perform a linear lifting movement.
  • the abrasive belt holder has a forming tunnel that forms a forming channel with an inlet and an outlet for the passage of the abrasive belt.
  • the forming tunnel encloses the forming channel in such a way that the tunnel wall forms the outer boundary of the forming channel.
  • a grinding belt can be fed to the entry side of the shaping channel, which belt exits at the exit side of the shaping channel folded in the middle in the longitudinal direction of the grinding belt.
  • the forming channel has a round cross section on the inlet side and a slot-like cross section on the outlet side.
  • the deburring tool according to the invention allows the grinding belt to be pulled out and cut off a predefined piece and, if necessary, then to be pressed firmly together again. This process can ideally be automated and therefore ensures consistent quality.
  • the deburring tool is accommodated in a machine housing which also accommodates a grinding belt rolled up into a grinding belt roll, the grinding belt being able to be fed to the entrance of the forming channel, in particular via a deflection roller.
  • the abrasive tape roll with a large supply can be accommodated in the deburring tool, as a result of which a large supply of abrasive tape is available during processing and an essentially continuous machining process can be carried out despite frequent replacement of the abrasive tape.
  • a sufficient supply enables frequent replacement of the grinding belt and thus ensures deburring with consistently high quality.
  • the abrasive belt 24 on the abrasive belt roll 26 has twice the width as at the exit 22.
  • the abrasive belt 24 is namely formed in the forming channel 18 and is thereby folded centrally in the longitudinal direction of the abrasive belt 24, i.e. along the center line of the abrasive belt 24. That is, in the longitudinal direction of the grinding belt 24, a folded edge is created in the middle. The result is that at the exit 22 the sanding belt is only half as wide as on the sanding belt roll 26.
  • the tubular section 30 has fastening means 34, e.g. a screw, with which the funnel-shaped section 32 can be firmly connected to the tubular section 30.
  • fastening means 34 e.g. a screw
  • the sword 42 can be omitted.
  • Both chambers 50, 52 are separated from one another by a partition wall 58 which can be displaced in the hup direction.
  • the partition wall 58 is rigidly connected to the forming tunnel 16, for example by pressing or gluing or by a positive connection.
