Definitions

  • the invention relates to a cutter head, in particular a planer cutter head, with the features of the preamble of claim 1.
  • a known cutter head of the type mentioned for processing wood has a support body which is provided with several receptacles for knives along its circumference at equal intervals.
  • the receptacles are open radially outwards and extend parallel to the axis of rotation of the support body.
  • a pressure jaw movable relative to the supporting body and the respective knife is provided in each receptacle.
  • the invention is therefore based on the object of improving a cutter head of the type described at the outset. This object is achieved according to the invention by a cutter head with the features of claim 1.
  • Fig. 1 is an end view of the embodiment in the prestressed
  • a planer cutter head for processing wood or plastic has a support body 1 made from a cylinder, which is provided with a central through bore 3 for receiving a shaft. The center of the Through hole 3 defines the axis of rotation of the support body 1.
  • the support body 1 is preferably made of aluminum.
  • the support body 1 has two mutually opposite, groove-like receptacles 5, which are open radially outwards and extend parallel to the axis of rotation of the support body 1.
  • the planer knife head according to the invention can also have a different number of receptacles, the receptacles being provided at equal intervals in the circumferential direction in order to avoid unbalances.
  • a further part of the clamping device is a pressure jaw 17, which is movable along this flank with at least one component in the radial direction.
  • the pressure jaw 17 has the shape of a wedge, which has a tapering end that points outwards from the receptacle 5.
  • at least one clamping screw 19 is provided, which engages with the pressure jaw 17 in such a way that the pressure jaw 17 can be moved with play by means of this clamping screw 19 both inwards and outwards .
  • the clamping screw 19 has an annular groove in its head, into which a projection of the pressure jaw 17 engages with little play.
  • the pressure jaw 17 is in a radially outer position.
  • the relevant normal force for this friction is the clamping force of the clamping device, in particular the pressure jaw 17.
  • the clamping screw 19 initially takes the pressure jaw 17 radially inwards.
  • One or more compression springs 35 are provided between the pressure jaw 17 and the holder strip 21. Each compression spring 35 is supported in a blind hole in the pressure jaw 17 and is attached to the holder strip 21 at one end.
  • This attachment point lies radially further inward than the contact point formed by the positioning surface 29 and the contact surface 31 between the holder strip 21 and the stop strip 9.
  • the pressure spring 35 comes into effect by the movement of the pressure jaw 17 in such a way that it comes into play Exerts torque on the holder bar 21.
  • the holder bar 21 pivots about an edge 29 'at the edge of the positioning surface 29.
  • the edge 29' is the part of the holder bar 21 which extends under the stop bar 9 the furthest.
  • the pivoting movement of the holder bar 21 is directed due to the position of the attachment point of the compression spring 35 so that the holder bar 21 moves away from the knife 7 towards the pressure jaw 17.
  • the positioning surface 29 moves away from the contact surface 31, however the edge 29 'remains in linear contact with the contact surface 31.
  • the dimensions, angles, movement paths or swiveling ranges of the positioning groove 23, the positioning projection 25, the pressure jaw 17 and the holder bar 21 are selected so that the holder bar 21 can pivot into a position in which it releases the knife 7, and this can be removed radially outwards.
  • the parallelism between the free surface 33, the contact surface 31 and the positioning surface 29 in the tensioned and pretensioned state ensures that even after grinding the breast 13 due to the displacement of the holder strip 21 parallel to the free surface 33 when tensioning, the distance between the new cutting edge 7 'and the axis of rotation of the support body 1, that is to say the new radius of the flight circle, coincides with the old radius.
  • the knife 7, the stop bar 9, the pressure jaw 17 and the holder bar 21 extend exactly like the receptacle 5 parallel to the axis of rotation of the supporting body 1, preferably over its entire length. For the production of these parts, it is advisable to use profile bars and saw them to the correct length.
