Definitions
- the invention relates to a cutting device according to the preamble of the statements 1 and 6.
- a cutting device is disclosed in the document US-A-53 88 490, which is the closest State of the art is considered.
- Such cutting devices are known in the art known. In these usually the procedure is that the cutting tool so far delivered to the anvil roll is that even at maximum cutting forces still sufficient Cutting action is given.
- the invention is therefore based on the object, a Cutting device of the generic type to improve such that the cutting tool as long as possible having.
- the support ring learns even if this is made of steel, due to the bearing force a deformation in the radial direction, that is, that the radial extent of the support ring relative to the Rotational axis reduced, with the varying contact force to leads that the reduction of the radial extent of Support ring is not constant, but with the varying Contact force also varies.
- Such varying elasticity would be, for example feasible in that the material elasticity of the support ring formed directly varying, for example by material or structural changes, which for example by diffusing elements into the structure of the support ring is feasible.
- the support ring a to confer variable elasticity through shape variation.
- a shape variation provides that the support ring Material formed with homogeneous elasticity properties is, however, by varying the shape of the support ring and the Elasticity of the same can be varied.
- the support ring in terms of his perpendicular to the azimuthal direction extending cross-sectional areas has a cross-sectional area variation.
- Such a cross-sectional area variation can be, for example by providing a support ring with constant Cross section and introduction of suitable recesses in make this.
- a particularly simple way of such a cross-sectional variation is when the support ring in one Direction transverse to the radial direction and transverse to the azimuthal Direction has a varying shape.
- Such a shape variation can be, for example, by introducing yourself extending in this direction recesses in the support ring realize with otherwise constant cross section.
- Such recesses may expediently, for example outgoing from an outer edge, across to formed azimuthal direction extending recesses be.
- An embodiment not according to the invention looks before that the support ring has a homogeneous material elasticity and maintains an unchanged form and that the reduction of the Deformation of the support ring at the transition from maximum contact force thereby taking into account the minimum contact force is that the effective at minimum contact force cutting sections have a greater extent in the radial direction as the cutting portions at which the bearing force maximum and the cutting force is minimal.
- the support ring With regard to the arrangement and design of the support ring are the most different not inventive embodiments conceivable. That's the way it would be conceivable to provide the support ring as a separate ring, which sits next to the cutting tool, however then the precision of the supporting action by the support ring relative problematic to the cutting tool. That's why preferably provided that the support ring on the cutting tool sit and go for example the support ring due a uniform processing together with the cutting tool same concentricity precision as the cutting tool having.
- Support surfaces are arranged directly on the anvil roll, so that a uniform centric machining of the support surfaces and the anvil surfaces is possible.
- the support surfaces can then be produced particularly simply if they form part of the anvil surfaces, because in this case only an area with the desired Precision is to produce.
- FIG. 1 and 2 each shown in section Cutting device according to the invention comprises as a whole with 10 designated machine frame, which two at a distance having mutually arranged bearing parts 12 and 14.

- the lower bearing support 20 is on the one hand between the side supports 16 and 18 out and on the other hand sits firmly on a base plate 24 of the machine frame 10.
- the bearing carrier 20 has a bearing receptacle 26, in which a designated as a whole with 28 lower pivot bearing its outer bearing ring 30 is inserted, wherein the outer Bearing ring 30 with its outer peripheral side on an inner surface the bearing seat 26 abuts.
- the bearing ring 30 is while in the bearing receiver 26 by an outer holder body 32 and an inner holding body 34 fixed with the retaining rings 36 and 38 on lateral annular surfaces of the outer bearing ring Abut 30 and thus this in the bearing mount 26 fix.
- the outer holder body 32 still includes at the same time a cover 40th
- the upper bearing support 22 is between the side supports 16 and 18 are guided and in a direction 42, which parallel to Extension of the side support 16 and 18 extends in the direction the lower bearing support 20 arranged adjustable. Also the upper bearing carrier 22 has a bearing receptacle 46, in which an upper pivot bearing 48 is inserted.
- the upper pivot bearing 48 is with its outer bearing ring 50 in held in the same way in the bearing seat 46 fitting as the lower pivot bearing 28 with the outer bearing ring 30 and
- an outer holding body 32 and an inner Holding body 34 is provided, which formed in the same way are as provided for in the lower bearing carrier 20 Holding body and in the same way the outer bearing ring 50th fix the upper pivot bearing 48.
- the upper bearing support 22 in turn is supported by a as a whole with 60 designated pretensioner on a Abutment 62 from which, at a parallel to the base plate 24 extending upper plate 64 is held, wherein the upper plate 64, the bearing parts 12 and 14 also with each other connects and also the side members 16 and 18 relatively fixed to each other.
- a tool shaft 82 rotatably mounted about a rotation axis 84, wherein the tool shaft 82, for example, through the Bearing part 12 extends therethrough and on its rotating Tool 80 opposite side one over the bearing part 12 protruding drive stub 86 has, over which by means of a drive, for example a motor Rotary drive of the rotating tool 80 takes place.
- a drive for example a motor Rotary drive of the rotating tool 80 takes place.
- the rotating tool 80 is characterized by the arrangement of the upper Pivot 48 in the upper bearing supports 22 and their displaceability in the direction 42 in the direction of the anvil roller 70th movable.
- the biasing means 60 which on the Upper bearing support 22 act, is the rotating tool 80th biased in the direction of the anvil roll 70 that this as Whole acts with a biasing force V on the anvil roll 70.
- the rotating cutting tool 80 now has to cut a whole designated 90 and between the rotating cutting tool 80 and the anvil roll 70 passed Material web 90 cutting 92, which of for example, to the rotation axis 84 cylindrical Cutting base in the radial direction to the axis of rotation 84th with a constant radial extent with respect to the axis of rotation survive.
- the cutting edge 92 includes two in the azimuthal direction to the axis of rotation 84 extending Cutting edge 92 a, which in transverse to this Crossing cutting edges 92b, which then pass through a chisel edge 92c, which is approximately perpendicular to the azimuthal direction 96 and thus approximately parallel to the axis of rotation 84, connected are (Fig. 3).
- the cutting edge 92 has two transverse cutting edges 92c and 92c ', starting from those in opposite directions Directions in each case the cutting edges 92b and 92b ', then pass into the cutting legs 92a, which the on either side of the cross cutters 92c and 92c ' Blade edges 92b and 92b 'interconnect, as enlarged in Fig. 3 and further enlarged in part shown in Fig. 4.
- the rotating cutting tool 80 so with two rotatably connected support rings 100th and 102 provided, for example, on both sides of the Cutting 92 are arranged coaxially with the axis of rotation 84 and while support surfaces 104 and 106 have, for example are arranged cylindrical to the axis of rotation 84 and on Support surfaces 108 and 110 of the anvil roll 70 rest, wherein the support surfaces 108 and 110, for example, by subregions the anvil surface 76 can be formed.
- the support takes place in each case via the support ring sections 104s and 106s, on respective support surface sections 108s and 110s of the support surfaces 108 and 110 sit, wherein when turning the rotary tool 80th opposite to the direction of rotation of the same sequential arranged support ring portions 104s and 106s with opposite to the direction of rotation of the anvil roll 70 in succession arranged support surface portions 108 s and 110 s cooperate.
- each cooperating support ring sections 104s, 106s and support surface portions 108s and 110s take on a total of a bearing force A, with which is the rotary cutting tool 80 on the anvil roll 70 is supported and which one of the biasing force V covered part of the same represents.
- the biasing force V not only leads to the formation of the Support force A, which on the support rings 100 and 102 on the anvil roll 70 acts, but also to a cutting force S, which is related to one in the respective cutting portion 92s effective cutting length.
- Transverse cutting edge 92c forms the effective cutting portion 92s, which with the corresponding Ansbßphilabites 76s cooperates, since the effective cutting length of the extension the cross cutting edge 92c perpendicular to the azimuthal direction 96 corresponds. At this point is to cut through the material 90 the largest cutting force required.
- the invention provides that elastic behavior of the support rings 100, 102 in the azimuthal direction 96 to vary.
- Fig. 1 to 4 are the support rings 100 and 102 with cutouts 120, 120 ' provided, for example, from an outer edge 122 the support rings 104, 106 in the direction approximately parallel to Rotate axis 84 in the respective support ring 100, 102 hineinerumblen and thus a width B of the support ring 100, 102 reduce from a width Bmax to a width Bmin.
- One such, with respect to its width transverse to the azimuth direction 96 reduced support ring 100, 102 deformed at the Position with reduced width at constant contact force A stronger, so that the extension of the section 120 is selected can be that the deformation of the support ring 100, 102 at the width Bmin and at maximum cutting force Smax minimum Contact force A in the radial direction to the axis of rotation 84 approximately equal to the deformation in the radial direction, the at minimum cutting force Smin and thus maximum contact force A and maximum width Bmax of the support ring 104 occurs.
- the Shape of the section 120 can be chosen so that the transition from the maximum width Bmax to the minimum width Bmin either the increase in cutting force from Smin to Smax and thus the decrease of the bearing force from the maximum value to minimum value substantially corresponds.
- a second embodiment of an inventive Solution shown in Fig. 6 and 7, primarily no Adjusting the elasticity of the respective support ring 100 ', but the respective support ring 100 'is in the azimuthal Direction 96 seen in areas where the maximum Cutting force Smax occurs, with a flattening or depression 130, 130 'whose deviation from a cylindrical Circumference 132 substantially the change of Radial extent of the support ring surface 104, corresponds to occurs when the bearing force of its maximum Value at minimum cutting force Smin at the minimum value at maximum cutting force Smax passes.
- the second embodiment is due to the low radial extent of the recess 130, 130 'primarily of a little changed elasticity of the respective support ring 100 ', but from the fact that through the depression 130, 130 'is an immediate compensation due to the Variation of the contact force A reduced radial Extension of the corresponding support ring 100 takes place.
- the support rings 100 ' may be formed with substantially ideal cylindrical shape 132 at the radial extent R 1 to the axis of rotation 84 and it is instead of the recess 130, 130' a corresponding "increase" ⁇ the radial extent R 2 of the transverse cutting edges 92c provided to the axis of rotation 84 relative to the radial extent R 3 of the cutting limbs 92a, so that the larger radial extent of the support rings 100 'is accepted at minimum bearing force, but this does not deteriorate the cutting action of the cross cutters 92c, since this one by the amount .DELTA correspondingly greater radial extent with respect to the axis of rotation 84 than the cutting edges 92a, since in the area of the support rings 100 ', due to the maximum contact force A and the minimum cutting force Smin have a greater deformation in the radial direction.
