Definitions

  • the invention relates to a with interchangeable carbide inserts equipped knife head for woodworking.
  • Such 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 yourself on a counter surface of the cutter head body rear support plate can be formed.
  • a support plate In the recess are also positioning devices for radial and axial Alignment of the relevant insert provided in Shape of ground stop faces 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 Axial positioning means in the opening of the cutter head body and can be fixed radially.
  • the invention has for its object a cutter head with exchangeable 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.
  • the basic solution to the problem according to the invention is in that already the construction of the cutter head body a completely different one from the usual practice Conception does not get through his training more than a rotating body with milled openings for insert holder, but through training in shape a central hub with one piece and plate-like or wing-like protruding radially outward from the hub Poor enough, but relatively thin thickness for Inclusion of the cutting plates, these arms as support plates are designed for the inserts and the inserts directly by means of clamping screws on these support plate-shaped Poor are stretched.
  • this cutter head construction according to the invention has the basic advantage that with strong profiling the Cutting the insert, so with a large profile depth for Milling strong plastic profiles, a fast and problem-free profiling of the tool body itself possible is because the necessary profile can be easily and quickly integrated into the relatively thin support plate-shaped arms of the cutter head body can be ground in.
  • the relative thin design of the cutter head body an enormous weight reduction achieved, which is beneficial in many ways.
  • the clamping of the inserts can be because of the support plate-shaped Arms of the cutter head carrier are easily accessible for this are much easier to accomplish than with conventional cutter heads.
  • Another essential aspect of the invention is positioning the carbide cutting tips in the invention 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 mounting 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.
  • the axial positioning takes place the insert through 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 of the cutter head according to the invention. 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 according to the The invention consists of a cutter head body 1 and can be replaced thereon 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 exemplary embodiment, of 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 - in context with Figures 1 and 2 - can be seen that the cutter head body arms as support plates for the cutting plates 21 are trained and adequate, but relative have small thickness, as in the drawings as well 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 region 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 be.
  • This taper makes it easier, in particular, necessary Profiling according to the 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 stop knobs arranged at a distance 26 be formed as radial stop surfaces; Alternatively could also be the entire side edge 24 as a sharpened Stop surface may be provided. This on the inner edge 24 molded stop knobs 26 act radially on the inside radial stop surface formed on the relevant cutter head body arm 13 14 together.
  • the cutting plate 2 has an inclined Elongated hole 27, which, based on the axis of the cutter head, runs inclined in the axial / radial direction. Finally are two holes 28 in the insert 2 for receiving the clamping screws 3 are provided.
  • a fitting pin engages in the elongated hole 27 of the insert 2 15 a, which is inserted into the relevant cutter head body arm 13 is and with that of the lower side edge 23 with the as Flank surface 29 facing pressure piece serving knobs 25 of the slot 27 cooperates. Presses during assembly the insert 2 the user with the thumb on the as Pressure piece molded on knobs 25 of the lower side edge 23 the cutting plate to move this in the axial direction (based on the Press the knife head), lies the lower side of the oblong hole 29 as an inclined surface on the fitting pin 15 and sets the axially acting pressing force partially into a radially acting Component around which the two radial stop knobs 26 the radially inner edge 24 of the insert against the Radial stop surface 14 of the cutter head body arm 13 urges.
  • the through holes used to hold the clamping screws 3 28 in the insert 2 are larger than the corresponding ones threaded holes formed in the cutter head body arm 13 16 designed for the clamping screws, so that necessary positioning play for the insert 2 given is.
  • the clamping screws 3 are with accordingly large heads for a secure clamping of the inserts 2 to accomplish.
