Definitions

  • the invention relates to a cutter head, in particular a profile cutter head, with the features of the preamble of claim 1.
  • a cutter head according to the preamble is known for example from FR-A-2 443 318.
  • the known cutter heads of this type are used for machining, for example for the production of profiles, solid wood and wood-based materials.
  • a disadvantage of these known tools is that they can usually only be used as a single or universal cutter head, but cannot be integrated into tool sets. Furthermore, the range in which the diameter and the cutting width can be selected is often not sufficiently large.
  • Another disadvantage is that the use of light metal for the base body is problematic since the clamping forces can lead to notches in the receptacles. If the clamping elements and the knives are secured by a pin-hole connection, then pin deformation can occur, particularly with unilaterally protruding profiles, which leads to a change in the position of the clamping elements and knives, which can lead to surface defects and an increase in residual unbalance . Furthermore, these known tools do not provide the minimization of pre-splitting necessary for a clean surface in solid wood processing, since the clamping elements have no profile contour below the cutting edge of the knife.
  • FR-A-2 443 318 it is proposed, in order to improve the clamping device, to provide each clamping element on the radially outer end on the side facing the knife with a convex contact surface and each knife on the side facing the clamping element with a concave contact surface.
  • the clamping force is transmitted from the clamping element, which is rotatably mounted at its radially inner end by means of a semi-cylindrical material section, to the knife via the contact line of the two differently curved contact surfaces.
  • DE-A-26 53 222 discloses a tensioning device with a two-armed, rotatably mounted tensioning element, which is pressed by the pressure force generated by a tensioning screw against an arbitrarily shaped and protruding knife compared to the tensioning element, which knife or pin Bead-groove connections are secured to the base body.
  • the object of the invention is therefore to create an improved cutter head. This task is solved by a cutter head with the features of claim 1.
  • the cutter head according to the invention can be used for the processing and in particular the profiling of solid wood, wood-based materials, plastics and non-ferrous metals, either as a single tool or in such a way that it is integrated in tool sets.
  • the tools can be designed with a bore, with a shank and with a defined profile.
  • the range of dimensions of the cutter head according to the invention is substantially larger than in the known cutter heads and can be selected continuously with constant profile accuracy.
  • the material for the knives and the cutting geometry can be optimally selected for the corresponding area of application.
  • the use of light metal for the base body is also possible without any problems, since the material of the base body is only exposed to a compression load due to the clamping means. It is therefore possible to achieve a considerable reduction in weight, good handling, low residual unbalance and thus also protection of the storage.
  • each tensioning element has a semi-cylindrical material section projecting over the pressure surface, which extends in the axial direction of the base body and engages in a groove of the receptacle which is semicircular in cross section.
  • the clamping screw engages in the area between the bearing point the clamping element and its pressure surface serving to rest on the knife.
  • the base body is preferably provided with a bore for each tensioning screw, which has a shoulder pointing away from the tensioning element for the abutment of a head of the tensioning screw and is aligned with a threaded bore of the tensioning element for the engagement of the tensioning screw.
  • the clamping screw can be an Allen screw with normal or fine thread, which is tightened by hand using a hexagon wrench or a Torx wrench.
  • Each of the clamping elements is profiled in accordance with the assigned knife and extends up to its cutting edge. It acts as a chip breaker.
  • the outer surface of the bearing body is advantageously profiled in accordance with the knives, the knives protruding only slightly beyond the base body. This ensures the required security against kickback.
  • the profiled, largely closed, round body shape minimizes noise emissions.
  • a radial connection between each clamping element and the associated knife is provided, in such a way that a material portion of the clamping element engages in a groove extending in the axial direction over the entire axial extent of the knife, which also via the entire axial extent runs.
  • a tongue and groove connection allows excellent centrifugal force protection to be achieved, even at the highest cutting gas speeds.
  • a cylindrical pin is advantageously provided for positioning the knife in the axial direction.
  • a profile cutter head has a base body designated as a whole by 1, which in the exemplary embodiment consists of light metal, but could also consist of steel or plastic and is provided with a central, axially penetrating bore 2 for receiving a shaft. Furthermore, the base body 1 has a plurality of receptacles 3 arranged uniformly distributed over the circumference of the base body, in the exemplary embodiment two diametrically arranged, identically designed receptacles 3, which are open towards its outer surface and extend from one end face to the other. The one shown on the right in FIG. 2 The flank of the groove-like receptacle 3 forms a flat contact surface 4 for a plate-shaped knife 5, which runs parallel to a radial plane of the base body 1.
  • the extension of the contact surface 4 from the outer lateral surface of the base body 1 into it is greater than the corresponding extension of the knife 5, and by an amount that is slightly larger than the diameter of a bore 6 which penetrates perpendicularly from the outer circumferential surface of the base body to the contact surface 4 and opens into the latter radially within the area which adjoins the areas for the installation of the knife 5 .
  • This groove 7 is used for the pivotable mounting of a plate-shaped clamping element 8 for the knife 5.
  • the plate-shaped clamping element 8 has along its edge closest to the central bore 2 a semi-cylindrical material section 8 'which extends over the entire axial extent of the clamping element 8.
  • This semi-cylindrical material portion 8 ' projects over the flat, the knife 5 facing pressure surface 9 of the clamping element 8, namely by an amount which is greater than the thickness of the knife 5, and engages in the groove 7 to form a pivotable mounting of the clamping element 8 a.
  • the pivot axis running parallel to the central bore 2 of the base body is therefore offset relative to the pressure surface 9 beyond the contact surface 4.
  • the semi-cylindrical material portion 8 ' together with the groove 7, positions the clamping element 8 in the radial direction and forms a positive connection between the clamping element 8 and the base body 1, which is able to absorb all centrifugal forces that occur.
  • the knife 5 is provided near its inner edge on the side facing the clamping element 8 with a groove 11 running parallel to the central bore 2 over the entire axial extension, in which engages a correspondingly designed rib 12 of the clamping element 8, which also extends over the entire axial direction of extension.
  • a cylindrical pin 13 protruding perpendicularly from the contact surface 4 serves for the axial positioning of the knife 5 by engaging in a securing groove 14 on the inner edge of the knife 5.
  • the width of the receptacle 3 is only slightly larger than the sum of the thickness of the knife 5 and the clamping element 8. Outside of this area is the Width of the receptacle 3 enlarged to a multiple, forming a rounded step, since this part of the receptacle 3 serves as a flute.
  • the two outer dash-dotted circular lines 15 and 16 are only intended to illustrate that flight circles of different sizes can be realized.
  • the clamping element 8 executes a slight pivoting movement when the clamping screw 10 is tightened, the clamping force can be carried over the entire pressure surface 9 up to the radially outer edge of the knife 5, which results in an excellent clamping of the knife 5. Since the clamping element 8 is profiled in accordance with the knife 5 and extends to close to the cutting edge of the knife 5 and is provided with a run-off slope 8 ′′, it acts as a chip breaker.
  • the base body 1 is also profiled in accordance with the knife 5, the knife 5 projecting only a little, for example 1 mm, beyond the outer surface area of the base body 1, as shown in FIG. 2. This ensures the necessary security against kickback, while the optimal design of the chip space and the design of the clamping element 8 as a chip breaker ensure a trouble-free chip flow and thus the reduction of dust generation.
