Definitions

  • the invention relates to hard metal cutting inserts bodies for loading the cutter head Cutter heads usually consist of a cutter head body in the form of a solid rotating body, on the circumference Cut-outs for the exchangeable carbide inserts and the associated clamping components are.
  • the holder takes place within these cutouts the carbide inserts usually by a clamping plate or a clamping wedge, which is tightened using clamping screws the insert is clamped and this in turn against one rear support surface spans, the support surface directly can be formed in the cutter head body or on a separate, also sitting in the recess and in turn on a counter surface of the cutter head body rear support plate can be formed.
  • positioning devices for radial and axial Alignment of the relevant insert provided in Shape of ground stop surfaces or dowel pins directly on the Cutter head bodies can be arranged or when in use a support plate can also be provided on this, wherein in this case, the support plate itself with appropriate Positioning means axially in the opening of the cutter head body and can be fixed radially.
  • a cutter head with exchangeable cutting inserts consisting of a cutter head body in the form of a solid rotating body with a number of radial arms formed thereon, each having a support surface to hold a knife plate.
  • the respective knife plate is with one Tensioning screw tightened on the cutter head body arm.
  • With carbide inserts the production of dowel holes is difficult, very complex and expensive, because with carbide only grinding, but not drilling is possible.
  • a hard metal insert which on an approximately radial Arm of a cutter head body can be clamped directly, with the following Features: it has a screw through hole that to hold a clamping screw with radial play is dimensioned, it has a radial stop surface for Cooperation with a radial counter surface on Cutter head body, it is with an axial / radial inclined sloping stop surface to interact with the clamping screw on the cutter head body arm educated.
  • the invention has for its object a cutter head with interchangeable carbide inserts for woodworking to create a significant relief with regard to the milling of profiles with a greater profile depth and the easy and correct positioning of the Brings cutting inserts in the cutter head body.
  • Another aspect of the invention is positioning the carbide tips in one Cutter head. This positioning must be in axial direction as well as in the radial direction with reference to the cutter head axes are made exactly.
  • conventional Cutter heads with their positioning devices must when installing the inserts in the cutter head, while the Clamping the relevant insert in the insert holder done, the insert by the user at the same time both in the axial direction against an axial Stop surface as well as in the radial direction against a radial Be pressed. This pressing takes place with one hand, while with the other hand Key tool actuated to tighten the screws becomes.
  • Convention cutter heads that inadvertently a clean contact of the stop surfaces the insert on the stop surfaces of the The insert holder or the cutter head did not work comes when the insert at any stage something is slipping or the pressure is actually not consistently in both directions simultaneously.
  • the axial positioning can the insert by a fitting pin, which on Knife head body arranged, namely in the support surface of the relevant cutter head arm is used and with a interacting with it, axially-radially-inclined, precisely ground or incorporated surface of the cutting plate cooperates, which preferably by a slot flank oblique slot or slot in the insert is formed, in which or which of the fitting pin intervenes.
  • Figures 1 to 3 show the basic construction a cutter head. Although there as an embodiment one cutter head with two with 180 ° angular distances interchangeable carbide inserts is shown, this construction applies in an analogous manner also for cutter heads with 3, 4 or even more exchangeable Knife plates, which also depends on the size and diameter of the knife head depends.
  • the cutter head shown as an embodiment consists of a cutter head body 1 and interchangeable clamped carbide inserts 2.
  • the cutter head body 1 consists of a shaft 11 for clamping, a hub part 12 formed in one piece therewith and a number, two in the present embodiment, of the radially projecting from the hub part 12 and thus integrally formed plate-like arms 13 which each carry one of the cutting plates 2.
  • Fig. 3 shows a cross section along the section line III-III in Fig. 2 by a cutting plate 2 and this bearing cutter head body arm 13. From this is - in context with Figures 1 and 2 - can be seen that the cutter head body arms as support plates for the cutting plates 21st are trained and adequate, but relative have a small thickness, as in the drawings can be seen (particularly clearly visible in the right half of FIG. 1 and in FIG. 3) in the area near the hub can be thicker and thinner in the radially outer area, the reduction in thickness can be continuous or how shown, graduated with the transitions producing Inclined surfaces can be formed.
  • the thinner radial outer part can also, as can be seen from the drawings, taper conically; also above and possibly also below (the latter not shown) may have an oblique taper the edge region of the cutter head body arm his.
  • This rejuvenation makes it easier, in particular, necessary Profiling according to the cutting insert profile continue to work into the cutter head body arms, this incorporation in the tapered thinner edge areas the arms 13 without the need for excessive material removal and thus take place quickly and easily can.
  • the cutting plates 2 are, as shown in Figures 1 to 3 with the help of 2 clamping screws 3 with a large head directly clamped to the relevant cutter head body arm 13.
  • the preferred means for exact positioning of the Cutting plate 2 on the relevant cutter head body arm 13 are shown in Fig. 4. However, there are the clamping screws 3 omitted.
  • FIG. 4 shows a cutting plate 2 in a top view and has a radially outer cutting edge 21, an upper side edge 22, which can also serve as a cutting edge, a lower side edge 23 and a radially inner edge 24.
  • On the lower side edge 23 is preferably a rounded one Knobs 25 formed as a pressure piece.
  • On the radially inner one Edge 24 can have two spaced stop knobs 26 be formed as radial stop surfaces. This on the inner edge 24 molded stop knobs 26 act radially on the inside radial case formed on the relevant cutter head body arm 13 can be seen (particularly clearly visible in the right half of FIG. 1 and in FIG.
  • the reduction in thickness can be continuous or how shown, graduated with the transitions producing Inclined surfaces can be formed.
  • the thinner radial outer part can also, as can be seen from the drawings, taper conically; also above and possibly also below (the latter not shown) may have an oblique taper the edge region of the cutter head body arm his. This rejuvenation makes it easier, in particular, necessary Profiling according to the cutting insert profile continue to work into the cutter head body arms, this incorporation in the tapered thinner edge areas the arms 13 without the need for excessive material removal and thus take place quickly and easily can.
  • the cutting plates 2 are, as shown in Figures 1 to 3 with the help of 2 clamping screws 3 with a large head directly clamped to the relevant cutter head body arm 13.
  • the preferred means for exact positioning of the Cutting plate 2 on the relevant cutter head body arm 13 are shown in Fig. 4. However, there are the clamping screws 3 omitted.
  • FIG. 4 shows a cutting plate 2 in a top view and has a radially outer cutting edge 21, an upper side edge 22, which can also serve as a cutting edge, a lower side edge 23 and a radially inner edge 24.
  • On the lower side edge 23 is preferably a rounded one Knobs 25 formed as a pressure piece.
  • On the radially inner one Edge 24 can have two spaced stop knobs 26 be formed as radial stop surfaces. This on the inner edge 24 molded stop knobs 26 act radially on the inside on the relevant cutter head body arm 13 formed radial
