Definitions

  • the invention relates to a cutter head according to the preamble of claim 1.
  • a hydraulic clamping bush is used to clamp the knives of known knife heads, in which the pressure medium is supplied via pistons.
  • the pressure parts for clamping the knives are pressed outwards, the knives being secured in the receiving grooves.
  • a disadvantage of these known cutter heads is that the clamping pistons in the cutter carrier lie radially between the receiving grooves and a through opening for the spindle of the cutter head, which can lead to a weakening of the cutter carrier in the radial area.
  • the knives can loosen if the hydraulic clamping bush or a clamping piston of the knives is leaking.
  • the invention is based on the object of designing a knife head of this type in such a way that the knives are securely clamped in a simple manner and without weakening the knife carrier can.
  • the knives are clamped mechanically through the pressure pieces of the pressure part.
  • the knife holder of the knife head according to the invention thus has high strength and stability. This has the advantage that a relatively large number of receiving grooves can be provided with a small mutual distance, so that the knife carrier according to the invention can be equipped with a larger number of knives in order to achieve a high processing quality and a high feed rate.
  • the pressure parts can also be easily manufactured and can be adjusted with the help of the adjusting part so that the respective knife is held securely. Since the pressure part consists of individual, adjacent pressure pieces, long knives can be clamped perfectly in the grooves. A high clamping force is exerted on the knife over the length of the knife via the individual pressure pieces.
  • the cutter heads according to FIGS. 1 to 10 are used in wood and plastic processing machines for planing, profiling and Like. Used. When used, they are arranged on a spindle (not shown) and connected to it in a rotationally fixed manner. For high feed speeds and high surface quality, the cutter heads are preferably clamped hydraulically on the spindle.
  • the knife head according to FIGS. 1 to 3 has a cylindrical knife carrier 1 which has, along its circumference, receiving grooves 2 for knives 3 arranged therein at a distance one behind the other.
  • the grooves 2 have a front view acc. Fig. 1 approximately trapezoidal shape. They taper outwards by their opposite side walls 4 and 5 converging outwards.
  • the floor connecting the side walls consists of three floor sections 6, 7, 8.
  • the floor sections 6 and 8 each close perpendicular to the side wall 4 and 5 and are connected to one another via the central floor section 7, which runs approximately perpendicular to the floor section 8. It forms a step between the bottom sections 6 and 8.
  • the bottom section 8 lies deeper than the bottom section 6 with respect to the circumference of the knife carrier 1.
  • the knife 3 rests on the longer wall 5 with its knife back 9 which is preferably provided with toothing (not shown) which is approximately axially parallel.
  • the knife 3 is secured with a clamping unit in the receiving groove 2.
  • the clamping unit has a pressure part 10 and a clamping piece 11, which has an approximately rectangular cross section.
  • the one broader long side of the clamping piece 11 is chamfered and lies with the flat inclined surface 13 against the chest surface 14 of the knife.
  • the inclined surface 13 is parallel to the side wall 5 of the receiving groove 2.
  • the radially outer narrow side 15 of the clamping piece 11 has a chip groove 16.
  • the knife 3 lies with its flat narrow side 18 facing away from the knife edge 17 on the base section 8, but can also be at a distance from it.
  • the clamping piece 11 With the pressure part 10, the clamping piece 11 is actuated, with which the knife 3 is clamped in the receiving groove 2.
  • the clamping piece 11 preferably extends essentially over the entire axial length of the knife carrier 1 and the knife 3, while the pressure part 10 is shorter than the clamping piece 11 (FIG. 2).
  • the pressure part 10 lies in a cross-sectionally U-shaped longitudinal groove 19 in the radially inner underside 12 of the clamping part 11, which is open to the radially inner, flat narrow side 12 of the clamping part 11 and of side walls 20 and 21 and which extend in the longitudinal direction of the clamping part 11 a floor 22 is limited (Fig. 1).
  • the longitudinal groove 19 has radial widenings or depressions 23 and 24 (FIGS. 2 and 3) provided in the end, in the area of which the longitudinal groove 19 has a greater depth than in the remaining area.
  • the longitudinal groove 19 is delimited at both ends by end walls 19a and 19b of the clamping part 11 (FIG. 2).
  • the end walls are penetrated by bores 25 and 26 for a stop 27 and an actuator 28.
  • the bores 25, 26 each run obliquely from the end faces 60 of the clamping part 11 in the direction of the bottom section 6.
  • the pressure part 10 consists of several, in the embodiment of seven pressure wedges 29 to 35, each having the same round cross section and trapezoidal longitudinal section.
  • the pressure wedges 29 to 35 are arranged in series to form a round rod and abut one another, as shown in FIG. 2.
  • the middle pressure pieces 30 to 34 are each of the same design.
  • Pressure wedges 30, 32, 34, but one after the next, are arranged identically, and rest with their larger base area 36 to 38 on the groove bottom 22.
  • the pressure wedges in between 31, 33 are in the untensioned state with their smaller base 39 and 40 on the groove bottom 22.
  • the end pressure wedges 29 and 35 have unevenly long side surfaces 41 to 44.
  • the outer side surfaces 41 and 44 are shorter than the other side surfaces 42 and 43, which are of the same design as the side surfaces 45 and 46 of the adjacent pressure wedges 30 and 34 against which they rest.
  • the pressure part 10 rests with the one pressure wedge 29 on the stop 27, which in the exemplary embodiment is formed by a screw. It is screwed into the bore 25 designed as a threaded bore.
  • the actuating part 28 On the side surface 44 of the other end pressure wedge 35 is the actuating part 28, which is designed like the stop 25 as a screw.
  • a holding part 47 is provided which is fastened to the clamping part 11 and is advantageously a holding plate (FIGS. 2 and 3). It is thin and fastened to the clamping part with screws 48 and 49.
  • the screws 48 and 49 are screwed into bores 50 and 51 which are provided axially adjacent to the groove 19 and below the bores 25 and 26 in the end walls 19a, 19b of the clamping part 11 (FIGS. 2 and 3).
  • the pressure wedges 29 to 35 are preferably made of round material, so that they can be easily manufactured. However, they can also have a different cross section, for example a square cross section. With the holding plate 47, the pressure wedges are held in their position shown, in which they lie against one another with their side surfaces or wedge surfaces 42 to 46 and 52 to 59 and in the untensioned state with the narrow ones or wide base sides of their trapezoidal cross section lie against the bottom of the longitudinal groove 19. If, as in the exemplary embodiment, the pressure wedges 29 to 35 have a circular cross section, they rest on the groove base 22 and the holding plate 47 with line contact (FIG. 1). In the axial direction, the pressure wedges are located between the stop 27 and the actuating part 28.
  • the clamping piece 11 with the pressure part 10, the stop 27, the actuating part 28 and the holding part 47 can be connected to form a preassembled unit which as a whole for securing the position and bracing the Knife 3 is inserted into the associated receiving groove 2.
  • a spring instead of the pressure or tension screw as the setting part 28, a spring, a hydraulic or pneumatic piston can also be provided, with which a hydraulic or pneumatic medium can be actuated for tensioning the pressure wedges 29 to 35.
  • the pressure or tension screw 28 is screwed in the direction of arrow P in FIG. 3 into the bore 26 of the tensioning part 11.
  • the screw 28 has a pressure piece 61 at the free end, with which it rests on the wedge surface 44 of the pressure wedge 35.
  • the axis of the screw 28 and the pressure piece 61 is perpendicular to the wedge surface 44.
  • the latter Under the force acting on the clamping part 11, the latter is pressed against the knife 3 in such a way that it is clamped firmly in the receiving groove 2 between the inclined surface 13 of the clamping part and the adjacent side wall 5 of the receiving groove and is thereby securely secured in its position.
  • very long knives 3 can be clamped perfectly over their entire length. Since the pressure part 10 consists of individual pressure pieces lying against one another with wedge surfaces and which are short in comparison to the length of the tensioning part 11, the pressure pieces 29 to 35 need not be manufactured exactly with respect to the tensioning part 11. In each case the but one after the next pressure pieces are pressed firmly against the groove bottom 22 of the clamping part 11 due to the design described.
  • the embodiment according to FIG. 4 differs from the previously described exemplary embodiment essentially in that the pressure part 10 'lies outside the receiving groove 2' in a longitudinal groove 19 'of the knife carrier 1'. It is designed essentially the same as the longitudinal groove 19 in the embodiment according to FIGS. 1 to 3 and formed by a recess in the bottom 6 'of the receiving groove.
  • the longitudinal groove 19 ' is symmetrical to the receiving groove 2' and is closed to the outside by the holding plate 47 ', which is fastened with its longitudinal edges to the bottom section 6' and secures the pressure wedges located in the longitudinal groove 19 'against falling out.
