Definitions
- the invention relates to a profile cutter head with blades that can be resharpened without changing the profile and flight circle, which has the features of the preamble of claim 1.
- each knife holder is clamped by means of screws against the base of the recess in the base body receiving it.
- the knife carrier Radially inside the knife fixed on the knife carrier, the knife carrier has a strip-shaped projection which engages in a groove of the base body the deeper the smaller the thickness of the knife is due to the grinding on its chest for the purpose of resharpening. If the engagement in the groove is free of play, this positive locking means that at least some of the centrifugal forces acting on the knife can be absorbed, thereby preventing an increase in the flight circle due to the centrifugal force.
- such a fit is technically complex in terms of production.
- the screws must be tightened carefully.
- the invention has for its object to provide a profile cutter head with re-sharpenable knives without changing the profile and flight circle, which has advantages over the known profile cutter heads of the type in question and in particular realized without complex design means can be.
- This object is achieved by a profile cutter head with the features of claim 1.
- Such a profile cutter head requires no fits.
- the positioning of the knife holder and the knife attached to it takes place without fitting dimensions exclusively through the flanks of the grooves provided in the base body and the breast stop surface forming the contact surfaces for the transverse part of the foot of the knife holder.
- the force of the tensioning screw or tensioning screws as well as the centrifugal force presses the knife carrier with its knife against the surfaces serving for positioning, which is why the centrifugal force cannot change the position.
- the cutter head can therefore withstand high dynamic loads. This contributes to inexpensive manufacturing. Resharpening takes place on the knife chest and is therefore easy to carry out.
- the knife material can be used almost completely, so that throwing away valuable cutting material is avoided.
- the body is also reusable.
- the same knife carriers can be used for different profiles. As a result of the interchangeability of the knife carriers, a modular system is obtained. Therefore, cutting edge geometries and cutting materials that are adapted to the material can be used without any problems.
- the chip space can be optimally designed, which significantly reduces the amount of dust generated when working with wood.
- the backlash-free knife positioning ensures a high repeatability in the positioning.
- the base body can optionally be made of steel or aluminum, whereby aluminum leads to a lower residual unbalance and thus protects the bearings of the spindle of the machine.
- a low machine load also contributes to the fact that large axis angles can be selected for low power consumption and that the rake angle can be adapted to the material.
- the backlash-free form locking of the knives ensures high operator and operational safety.
- the feed can be done mechanically or manually.
- the tool according to the invention is easy to service. Simple and error-free resharpening can be carried out in a sharpening device.
- the tool is easy to clean thanks to its closed design. Large tensioning screws, which are easy to loosen, prevent over-tightening.
- the solution according to the invention can be used not only with cutter heads with a disk-shaped or roller-shaped base body, but also with cutter heads with a cranked, ie bell-like base body, the receptacles of which open towards the annular disk-shaped end face.
- the cutter head according to the invention can be used for profiling and joining, both as a single tool and as a tool set consisting of several individual tools.
- the knives are preferably HSS, stellite or HM-tipped knives of the breast stop surface 9.
- the area of the receptacle receiving the foot has a T-shaped cross-sectional profile, the transverse part of which is formed by the two longitudinal grooves, the flanks of which serve to rest the foot of the knife holder preferably lie in one and the same plane.
- the displaceability of the two arms of the foot in the longitudinal grooves in the direction of their depth and of the longitudinal part of the foot in the longitudinal part of the region of the receptacle receiving the foot is at least equal to the thickness of the the sharpenable layer of the knife selected when resharpening.
- the knife material can therefore be used up almost completely during resharpening.
- the reduction of the knife thickness due to the re-sharpening has no influence on the positioning of the knife and its holder as well as the play-free positive locking between the knife holder and the base body.
- the maximum allowable material removal on the knife breast during re-sharpening can be determined in a simple manner by letting the longitudinal part of the foot come into contact with the boundary surface of the longitudinal part of the receptacle adjacent to the breast stop surface when the knife has reached its minimum thickness. As long as there is still a distance between these two surfaces, the knife can be resharpened.
- the positioning surfaces formed by the groove flanks preferably run at a right angle to a radial plane. Furthermore, the angle which the breast abutment surface forms with its adjacent positioning surface, as well as the angle which the clamping surface of the knife carrier forms with its adjacent positioning surface, is preferably less than 80 °.
- the clamping screw that bears against the clamping surface of the knife carrier, but rather a pressure pin with its end surface that is guided in a bore of the base body that runs perpendicular to the clamping surface. If, particularly for reasons of space, the pressure screw cannot be arranged coaxially with the pressure pin, the end of the pressure pin facing away from the clamping surface is chamfered. The longitudinal axis of the clamping screw then runs perpendicular to this inclined surface, the wedge angle of the inclined surface with respect to the longitudinal axis of the pressure pin preferably being selected to be greater than 30 °.
- the profile cutter head according to the invention is not only suitable for embodiments in which the axis angle is zero, ie the longitudinal axis of each recess runs parallel to the central longitudinal axis of the base body. Much more Axle angles other than zero can be provided, the cross-sectional profile of the receptacles and the knife carrier being able to be retained, that is to say neither a macro change is necessary for the receptacles in the base body nor for the knife yields.
- an axial stop projecting beyond its cross-sectional profile is defined for positioning in the axial direction at the foot of the knife carrier.
- the base body preferably lies with one end face concentrically to the shank on an end face thereof.
- This end face of the shaft is advantageously provided at a flange-shaped end which has a larger diameter than the rest of the shaft.
- the base body has a centering pin which projects beyond the end face resting on the shank and which engages in a centering bore of the shank without play.
- axially parallel through bores can be provided in the base body, which are aligned with threaded bores in the flange-shaped end section of the shaft and accommodate connecting screws.

- FIG. 7 shows an incomplete and partially sectioned side view of a fourth embodiment in the form of a shank tool
- FIG. 8 is an incomplete front view, partially in section and enlarged, of the embodiment of FIG. 7,
- FIGS. 7 and 8 are incomplete and partially sectioned end views of a modification of the embodiment according to FIGS. 7 and 8.
- the embodiment of the profile cutter head according to the invention shown in FIGS. 1 to 3 has a base body 2 made of steel or aluminum, provided with a central bore 1 for receiving a shaft, into which two receptacles 3 of the same design and arranged diametrically with respect to the central bore 1 are incorporated are. Because the axis angle at this
- the Cutter head is zero, the receptacles 3 run parallel to the longitudinal axis of the base body 2.
- Their cross-sectional profile is composed of a trapezoid-like area that widens towards the outer surface and a T-like one Region together, the longitudinal part of which extends radially inward from the trapezoid-like region to the transverse part formed by two longitudinal grooves 4 and 5.
- the two longitudinal grooves 4 and 5, which are open towards each other, are delimited radially outwards by a first positioning surface 6 and a second positioning surface 7, both of which lie in the same plane, which includes an angle of 90 ° with a radial plane.
- a boundary surface 8 adjoins the first positioning surface at right angles, to which a breast stop surface 9 adjoins, which is inclined with respect to a radial plane by the rake angle.
- the breast stop surface 9 is adjoined by one edge of a chip guide groove 10 machined into the base body 2.
- a likewise flat side surface 11 of the receptacle 3 encloses an angle of somewhat less than 90 °, to which a boundary surface 12 running parallel to the boundary surface 8 connects, which on the other hand adjoins the second positioning surface 7.
- the radial extent of the boundary surface 12 is significantly smaller than that of the boundary surface 8 because the side surface 11 is considerably wider than the breast stop surface 9.
- a knife holder 14 fitted with a resharpenable knife 1 3 is inserted, the axial length of which can be greater than that of the base body 2.
- the two knife holders 14 of the same design which are preferably cut to length from a correspondingly profiled rod, have a head part on the surface of which lies at the front in the running direction, the knife 13, which is soldered onto the knife carrier 14.
- the surface delimiting the knife carrier 14 to the outside is profiled in the same way as the knife 13. Since the knife edge is straight in the exemplary embodiment according to FIGS. 1 to 3, this surface lies in the plane defined by the free surface of the knife 13.
- the head is against the side surface 1 1 - 8 - area of the knife carrier 14 limited by a flat clamping surface 15 running parallel to the side surface 11.
- a T-shaped foot region adjoins the head region of the knife carrier 14 radially inward, the transverse part of which forms a first arm 16 engaging in the longitudinal groove 4 and a second arm 17 engaging in the longitudinal groove 5.
- the thickness of the arms 16 and 17 is less than the width of the longitudinal grooves 4 and 5.
- Radially outwards the first arm 16 through a contact surface 16 'and the second arm 17 through Contact surface 1 7 'limited.
- the contact surface 16 ' is intended for contact with the first positioning surface 6, the contact surface 17' for contact with the second positioning surface 7.
- both contact surfaces 16 'and 17' lie in one and the same plane.
- the distance of the boundary surface 8 from the boundary surface 12 of the base body 2 is greater by a little more than the resharpening path than the thickness of the foot longitudinal part of the knife carrier 14 measured in this direction.
- the foot longitudinal part is only a small distance from the boundary surface 12 of the receptacle 3.
- the foot middle part comes closer to the boundary surface 8 until it is only one with a minimal knife thickness Has a distance of about 0.2 mm from the boundary surface 8. This thin gap indicates that the knife 13 can no longer be resharpened.
- the first arm 16 dips more and more into the longitudinal groove 4 when the knife carrier 14 is positioned, while the second arm 17 is drawn more and more out of the longitudinal groove 5.
- a pressure pin 19 is arranged to be longitudinally displaceable and rests with its one end face on the clamping surface 15 of the knife carrier 14. The end facing away from this end forms an inclined surface 20 which encloses an angle of more than 30 ° with the longitudinal axis of the pressure pin 19.
- the end face of a clamping screw 21 bears against this inclined surface 20 and is located in a threaded bore of the base body 2 running perpendicular to the inclined surface 20.
- the inclined surface 20 implements the effective in the longitudinal direction of the clamping screw 21 robbing force into a clamping force acting in the longitudinal direction of the pressure pin 19.
- a disk-shaped axial stop 22 is fixed on one end face of the knife carrier 14 in the region of the free end of the first arm 16 in the embodiment with a screw.
- this axial stop 22 is in contact with the end face of the base body 2 in the region of the longitudinal groove 4.
- the knife carrier 14 When the knife carrier 13 has its correct axial position and the tensioning screw or screws 21 are tightened, the knife carrier 14 is first pushed as far to the left in a viewing direction according to FIGS. 1 to 3 until the chest surface 1 3 'of the knife 13 is in contact with the breast stop surface 9 of the base body 2. Then the force of the clamping - 10 - screw 21 so that the contact surfaces 16 'and 17' of the arms .16 and 17 are pressed against the positioning surfaces 6 and 7, respectively.
- the knife carrier 14 and the knife 13 are now exact without fits because they are free of play and also positively positioned with respect to the clamping force and the centrifugal force.
- the knife carrier 14 and the knife 13 are also positively connected to the base body 2 for the cutting force. The tool can therefore withstand high dynamic loads.
- the clamping screws 21 only need to be loosened slightly.
- the knife carrier 14 can then be taken out of the receptacle 3 in the axial direction.
- FIG. 4 differs from that of FIGS. 1 to 3 only in that it has an axis angle different from zero.
- the boundary surfaces of the recesses 103 of the base body 102 are rotated about the axis angle only in the open space plane.
- the cross-sectional profile of both the recess 103 and the knife holder 114 are therefore unchanged in comparison to the exemplary embodiment according to FIGS. 1 to 3. Therefore, because of the further design of the base body 102, the knife holder 114 and the knife 113, the statements can be made reference to the first embodiment.
- the knife carrier 1 14 can be cut off from the same profile bar as the knife carrier 14. It only has to be the cutting plane around the axis angle - 1 1 - be offset from a cross-sectional plane.
- Fig. 4 also shows that the knife holder 1 14 can protrude together with the knife 1 1 3 over one end face of the base body 102.
- the two clamping screws each arranged in a threaded bore of the base body 202, are identified by 221, the axial stop of the knife carrier 214 by 222. Because of the remaining details, reference is made to the explanations regarding the exemplary embodiment according to FIGS. 1 to 3, since the third exemplary embodiment corresponds to the first exemplary embodiment.
- FIGS. 7 and 8 show a shank tool.
- a cylindrical shaft 323 has a cylindrical flange 324 at its end and a central threaded bore at its other end, into which a screw 326 can be screwed.
- a base body 302 of a profile cutter head rests on the exposed end face of the flange 324 with its one end face.
- a central centering pin 327 protrudes over this end face of the base body 302, said centering pin free of play in a central centering bore 328 of the flange 324 intervenes.
- Two through bores of the base body 302 lying diametrically to the longitudinal axis of the tool are each aligned with a threaded bore 325 of the flange 324. Screws 329 clamp the base body 302 against the flange 324 without play.
- the base body 302 is provided with two diametrically arranged, identically designed receptacles 303 which, as shown in FIG. 8, have the same shape as the receptacles 3 of the first exemplary embodiment.
- the associated knife carriers 314 also have the same shape as the knife carriers 14.
- the connection between the knife carrier 314 and the base body 303 which connection is free of play and is positive for the clamping force, the centrifugal force and the cutting force, takes place by means of the two, as in the exemplary embodiments described above Positioning surfaces 306 and 307, the breast stop surface 309 and the clamping surface 31 5.
- the knife 313 soldered onto the knife carrier 314 is a plate made of hard metal, Stell ⁇ t or HSS steel.
- the solder layer is designated 330.
- the available space allows the tensioning screws 321 to be arranged in the base body 302 coaxially with the associated pressure pins 319.
- the pressure pin 419 and the tensioning screw 421 instead of an arrangement of the pressure pin and the tensioning screw, forming an angle to the lateral surface of the base body, like this 1 to 6 is the case, or a coaxial arrangement as in the embodiment according to FIGS. 6 and 7, if the space in the base body 402 allows this, the pressure pin 419 and the tensioning screw 421 also arrange so that they form an angle opening towards the center of the base body 402, as shown in FIG. 9.
