Definitions

  • the invention relates to a tool head according to the preamble of claim 1 and a method for inserting and clamping a cutting insert according to the preamble of claim 5.
  • a knife shaft for cutting woodworking machines is known, in particular for planing machines. It has a one-piece shaft body, which has several axially parallel grooves narrowing towards the lateral surface, in each of which sits a profiled disposable knife braced by a centrifugal wedge, which positively engages in a corresponding profiling of the side surface of a retaining strip lying between disposable knife and centrifugal wedge.
  • the retaining bar is immovably connected to the shaft body and elastically deformable. It is arranged at such a distance from the side wall of the groove that, when the centrifugal wedge is released, an intermediate knife can be easily pulled out in the longitudinal direction and a new knife can be inserted practically without play.
  • the retaining strip When the centrifugal wedge generates the clamping force by rotation, the retaining strip is pressed firmly against the disposable knife by slight elastic deformation, so that it remains firmly in place. However, the knife can only be clamped in a single, unchangeable position.
  • German utility model DE-U-8914 809 discloses a cutter head for machining wood, plastic and the like, in particular for longitudinal profiling of strips and plates, with a cylindrical base body which has a plurality of axially parallel grooves open to the lateral surface.
  • a knife is clamped in each groove between a side wall of the groove and a retaining strip, a toothing of the knife back engaging in a form-fitting manner with a corresponding toothing of the side wall.
  • the groove towards the outer surface of the base body is narrowed in a wedge shape.
  • a centrifugal wedge is arranged in this, which firmly clamps the knife between the holding bar and the other side wall when the base body rotates.
  • U.S. Patent Application No. 2002/0046632 discloses a tool body with one or more tool holders, in which cutting edges can be used, which are held by a clamping mechanism.
  • the US 2002/0046632 plan to re-sharpen the cutting edges and remove an equal amount from the cutting edge base, thus creating a new reference edge.
  • the inserted cutting edges have a groove at a distance from the cutting edge base, into which a protruding rib formed in the tool holder engages when the cutting edge is clamped in the holder.
  • the groove is provided on the flat side of the cutting edge opposite the cutting edge and prevents the cutting edge from slipping radially during operation.
  • the rib can alternatively be provided on the fastening wedge to achieve the same purpose.
  • U.S. Patent Application No. 2005/0265795 shows a tool head with a tool holder, in which a cutting edge can be clamped by means of a fastening wedge.
  • the cutting edge has a chamfer on the cutting edge base and opposite the flat side with the cutting edge, which creates the necessary space when the cutting edge is inserted into the tool holder opening.
  • the centrifugal wedge is first loosened by radially inward force, for example by a hammer blow.
  • the retaining strip which is slightly deformed in the tensioned state in the direction of the knife, returns in it; relaxed location back.
  • the seat of the knife is loosened to such an extent that it can be easily pulled out in the direction of the axis of the base body.
  • the knife can be inserted again in the axial direction, for example in a position that is shifted outward by a tooth width. As soon as the cutter head is rotated rapidly, the centrifugal force tightens the centrifugal wedge.
  • the knife is now firmly and precisely clamped. Since the centrifugal wedge is designed to be self-locking, it remains tensioned even after the cutter head has been stopped.
  • An advantage of the knife head described is that the screws do not have to be loosened when changing the knife.
  • the disadvantage, however, is that the knife is only in the axial direction can be pulled out of the groove. This means that neighboring cutter heads must first be removed from the tool spindle before the cutter can be removed.
  • Knife heads with conventional knife holders without centrifugal wedges usually require several screws when using wide knives to attach the knives to the knife head. This requires more work when changing knives.
  • Another problem with such conventional cutter heads is that the pressure bodies are fastened with screws in a groove of the cutter head against the centrifugal force that arises during rotation. At high speeds, the centrifugal forces can cause the knife to shift slightly, which affects the accuracy of the woodworking and leads to greater tolerances.
  • Another aim is to provide a tool head in which a prior disassembly of tool heads adjacent to the tool head is no longer necessary when changing tools or knives.
  • Another goal is to propose a tool head that minimizes the work involved in changing tools.
  • Another goal is that when a tool is changed, the new tool is precisely adjusted in the radial and preferably axial direction.
  • the invention relates to a tool head, in particular a cutter head for a woodworking machine, with a cylindrical, conical or profiled base body for rotating machining of a workpiece.
  • the tool head has at least two tool holders arranged uniformly distributed over its circumference for holding a cutting insert.
  • the tool holders each have narrowing grooves in the radial direction, in each of which a cutting plate can be clamped between a first side wall of the groove and a closure element serving as a pressure jaw.
  • a centrifugal wedge which can be inserted into the groove, can press the locking element against the cutting plate and fix the latter in the tool holder.
  • a first interlocking connection is provided between the cutting plate and the first side wall, which fixes the cutting plate in the radial direction.
  • a second positive connection is provided between the closure element and the centrifugal wedge.
  • This arrangement of the interlocking connections namely between the insert and the tool head on the one hand and the closure element and the centrifugal wedge on the other hand, has the advantage that a relative movement between the closure element and the insert is possible when clamping because there is no interlocking connection between the insert and the closure element.
  • the proposed arrangement of the interlocking connections also allows the cutting insert to be inserted into the groove in the radial direction.
  • the centrifugal wedge advantageously has a bore with an internal thread into which a clamping screw with an external thread can be inserted.
  • the centrifugal wedge can be moved into the clamping position by rotating the clamping screw in a first direction and into the tool changing position by rotating the clamping screw in a second, opposite direction.
  • this tool holder has the advantage that the centrifugal wedge is preloaded outwards in the radial direction when the tool is clamped. This has the advantage that the centrifugal wedge and the cutting plate no longer move when the tool head begins to rotate.
  • the clamping screw is a threaded pin, on one end face of an attack means, for example a hexagon socket or a Torx screw driving profile, and on the second end face a preferably cylindrical screw head
  • an attack means for example a hexagon socket or a Torx screw driving profile
  • the screw head has a latching extension on the end face, which can engage with play in a corresponding blind hole in the groove base.
  • the blind hole and the latching extension are designed in such a way that radial pre-assembly of the clamping screw is possible.
  • a screw hole with an internal thread is advantageously provided in the base of the groove, and the shaft of the clamping screw has two threaded sections with opposite screw threads.
  • This has the advantage that, if the direction of rotation of the screw thread is selected appropriately, the centrifugal wedge moves away from the groove base when the clamping screw is screwed into the screw hole.
  • the clamping screw can be inserted rotatably but immovably in the axial direction into the bore of the centrifugal wedge. In this way, too, the centrifugal wedge can be pressed against the closure element by turning the clamping screw.

  • either the closure element or the centrifugal wedge is equipped with at least one magnet.
  • the provision of at least one magnet has the advantage that the cutting plate, which is advantageously made of a weakly magnetizable material, is held on the closure element. This has the advantage that the cutting insert is pulled towards the closure element in the tool change position. Because the insert is additionally tilted when the centrifugal wedge is released, it can be gripped easily with your fingers.
  • the at least one magnet is preferably inserted into a recess of the closure element flush with its surface.
  • This has the advantage that the cutting plate can lie flat against the closure element.
  • two spaced-apart recesses are provided, in which magnets are inserted flush.

  • a third positive connection is provided between the centrifugal wedge and the closure element for the lateral centering of the closure element. This is a particularly advantageous embodiment which, in conjunction with the second positive connection, enables the radial and axial adjustment of the cutting insert.
  • a cutting plate for the tool head of a woodworking machine has a cutting edge on a first side (knife chest) of the cutting plate and a positioning groove on the second side of the cutting plate opposite the cutting edge.

  • This insert has the advantage that it can be positively fixed directly in the tool body.
  • the chamfer is advantageously ⁇ 0.6 mm.
  • This chamfer which is significantly larger than known cutting inserts, has the advantage that an elastically deformable pressure element can spread when the centrifugal key is tensioned due to the increased free space between the groove wall and the cutting insert.
  • the enlarged chamfer therefore has a meaning in connection with the correct radial positioning of the cutting insert.
  • this functional surface is also relevant in terms of safety, since without it the brittle cutting inserts could break during clamping and fly away during operation.

  • the stop bar 85 and the depression 87 ie the depression 87 is wider than the stop bar 85 by a certain amount, preferably between 0.05 and 1.5 mm and particularly preferably between 0.3 and 1.0 mm the insert 15 is loosely inserted into the tool holder and rests on the shoulder 91 ( Fig. 9 ), the upper edge 117 of the stop bar 85 can substantially correspond to the inner side edge 119 of the recess 87.
  • the embodiment according to the Figures 13 and 14 differs from that of Figures 11 and 12 in that at least one pressure element 113b, but preferably two pressure elements 113b, is received in a separate blind hole 121 which is provided in the area of the shoulder 91 in the tool head body.
  • a blind hole 121 and a pressure element 113b are preferably provided symmetrically on both sides of the centering pin 79.
  • the functioning of the pressure element 113b is the same as that of the pressure element 113a, ie the part of the pressure element 113b protruding from the blind hole 121 and from the wall section 95 causes the cutting plate 15 to be centered radially when clamped.
  • a further modification of this embodiment is in the area of the lateral positioning the insert 15 located.
  • the cutting plate 15 has no U-shaped recess for the lateral positioning. For lateral positioning, the positioning pin 79 is axially outside the cutting plate 15 moved so that the cutting plate 15 can be struck on the left or right side of the positioning pin 79.
  • the Figures 15 and 16 show a further tool head 11c, in which the tool holder 13a represents a less deep cut than in the tool heads described above and the cutting plate 15a has only a small height and two cutting edges 92a, 92b.
  • the closure element 25c is also shorter than in the other exemplary embodiments.
  • the tool head 11c has a stop bar 85a which is integral with the tool body.
  • a centering pin is also not arranged in the center, but rather a lateral stop for the lateral centering of the cutting plate (not shown in the figures). Otherwise, the tool head 11c corresponds in terms of function and structure to the other tool heads, so that a more detailed description can be dispensed with.
  • the tool head 11d represents a flattening knife head, which differs from the previously described embodiments in that the tool holder 13 is not provided in the circumference but in the end face 123 of the tool head 11d. Due to this construction, the centrifugal forces generated when the tool head is rotating only act to a small extent on the closure element 25 and the cutting plate 15. In order to keep the centrifugal wedge 23 precisely in the groove 19, two spaced-apart reinforcing elements 125 projecting from the wall are provided in the groove wall 31 and cooperate in a form-fitting manner with corresponding grooves 127 in the centrifugal wedge 23.
  • a modified clamping mechanism is shown. This differs from those described above in that the clamping screw 29a only has a rear thread 99.
  • a head 129 is provided on the front of the tensioning screw 29a and is supported on the groove base 65, 67.
  • a centering extension 131 is formed on the head 129, which engages in the screw hole 60, which in this case does not have to have an internal thread.
  • the centering extension can also be dispensed with, since it is not required for clamping the insert.
  • the described embodiment of a tool head is otherwise not provided with a closure element, but the centrifugal wedge 23 acts directly on the cutting plate 15.
  • the embodiment according to Fig. 18 does not fall under the invention according to claim 1 and claim 5.
  • Die Figures 19 to 21 show an embodiment of a spring element 133, on the one hand, the function of the centering pin described above (see. Fig. 3 ) for the lateral alignment of the insert and on the other hand the pressure element for the radial positioning of the insert.
  • the spring element 133 has a rear clamping section 135, comparable to a heavy-duty clamping pin, which can be inserted into the pin hole 81.
  • a spring tongue 137 is formed on the tensioning section 135 with a terminal lug 139 which, when inserted into the pin hole 81, projects beyond the front wall section 95.
  • the spring tongue 137 presses with the nose 139 onto the closure element 25, pushes it away and thus facilitates the removal of the cutting plate 15 when the centrifugal wedge is released Fig. 21 ).
  • the tool head according to the invention is used as follows: To insert a new cutting insert into the tool head according to the Figures 1 to 3 the centrifugal wedge 23 is first brought into abutment with the base of the groove by turning the clamping screw as far as possible in the corresponding direction of rotation. In the tool change position then assumed, the centrifugal wedge 23 is tilted with respect to the first groove wall 27, so that a gap which opens in the radial direction is formed between the closure element 25 and the rear wall section 93 of the groove wall 27 ( Fig. 2 ).
  • the new insert can now be inserted into the gap, the centering pin 79 ensuring the correct lateral centering of the insert 15.
  • the cutting plate 15 rests on the shoulder 91.
  • the elastically deformable pressure elements 73, 113a, 113b can also touch the base of the insert or be arranged at a short distance from it. If the screw 29 is now rotated in the clamping direction, the pressure elements 73, 113a, 113b are clamped between the front wall section 95 and the closure element. These expand laterally and push the cutting insert radially outward, so that the cutting insert rests with the lower edge 100 of the groove 87 on the stop bar 85.
  • the position of the groove 87 and in particular of the lower edge 100 plays in relation to the cutting surface 108 an important role. This is the only way to ensure that the expansion of the pressure elements when clamping the tool is sufficient to ensure exact positioning of the cutting plate in the radial direction during the clamping process. In this way, an exact positioning of the cutting plate in the radial direction is ensured, which significantly increases the accuracy of the work to be carried out.
  • the screw 29 is rotated until the centrifugal wedge lies firmly against the closure element 25. The centrifugal force generated when using the rotating tool head increases the clamping force.
  • the tool head according to the invention is used, in particular, for the machining of wood, plastic and similar materials, in which the method for processing and for removing chips or particles is similar. Similar materials are, for example, cork, bone, plastic, light metal alloys, wood-based materials such as chipboard, fibreboard, plywood, etc. Cutting plates with a straight, convex or profiled cutting edge are used as tools.
  • the inserts consist of flat blades with a thickness between approximately 1 mm and 3 mm.
  • the cutter head is rotatably arranged in operation on a spindle of a woodworking machine, and further cutter heads can be attached directly adjacent to the spindle.
  • the centrifugal wedge (tensioning and loosening) can be adjusted by means of a single screw for all application widths.
  • the cutting insert is already pressed against the stop bar 85 in the direction of flight during clamping, so that the cutting insert can no longer move when the tool head is rotating.
  • the exemplary embodiments are each described by way of example with reference to a tool head which is circular-cylindrical in section, in which the tool is received in an axial groove (which is axially parallel to the axis of rotation).
  • the tool holder respectively.
  • the groove also runs at an angle to the axis of rotation (eg conical tool head). The groove can thus assume 3 spatial angles relative to the axis of rotation and thereby define a rake angle, offset angle and axis angle.
