Definitions
- the invention relates to a cutting tool with a support body according to the preamble of claim 1.
- cutting tools are known in which by means of screwing a cutting element is mounted in a receptacle of a supporting body. It is important that the contact surfaces of the clamping jaws, cutting elements and the seat of the cutting elements are flat to ensure a uniform contact pressure. In such a cutting tool problems occur during regrinding, since reground cutting elements are inclined with respect to the seat, so that the contact pressure is reduced, especially in the region of the cutting edge of the cutting element.
- the cutting edge then vibrates during the machining process, resulting in an unclean cut; In extreme cases, chips can penetrate between the seat and the cutting element. The same problem occurs when due to manufacturing tolerances no flat contact surfaces can be provided.
- the generic EP 1 574 308 A1 relates to a milling tool which is held in a slot-like receptacle in a base body.
- a jaw clamps a cutting element in the body firmly.
- the jaw is clamped by a screw and has a contact surface which is inclined slightly in the direction of the cutting element. An angular range of approximately 1 ° is indicated.
- the DE 11 95 934 B1 relates to a knife shaft for woodworking machines with wedge-shaped pressure bars. Clamping elements are movably mounted in a shaft body and press knife against the shaft body. The clamping elements are pressed by elastic means against the blades.
- the DE 92 10 363 U1 describes a cutter head with a base body which is provided with at least two evenly distributed over its circumference arranged recesses, in which knife by means of a clamping device, which has at least one clamping element and at least one cooperating with this and the body clamping screw, are set interchangeable.
- the BE 401 214 A1 relates to a knife shaft with a support body, in which recesses are arranged for receiving knives in the longitudinal extent of the blade shaft.
- a groove extending essentially parallel to the shaft axis is milled in the shaft body so that a part of the receptacle is formed only on a narrow web of the blade shaft.
- this surface is pressed against the cutting edge and clamped in the knife roller.
- the EP 1 568 453 A1 describes a Ringzerspaner with knife elements, which are held by clamping retaining rails on the ring body.
- the US 4,193,719 A describes a cutting tool with resharpenable cutting elements.
- the object of the invention consists in an improvement of the cutting tool with respect to the Thomasverhaltans and the Crulchkeit.
- the cutting element in the region of the cutting edge is also firmly clamped in his seat when it comes due to a reworking of the cutting element or due to manufacturing tolerances to deviations in the flatness of the contact surfaces of the cutting element. It also compensates for inaccuracies that can occur when the cutting element is inserted obliquely or the support body already has deformations as a result of prolonged use.
- the vibration behavior of the cutting element is positively influenced, so that a clean cut is made possible. Due to the possibility of re-sharpening of the cutting element, the tool costs are reduced, so that overall the efficiency of the cutting tool is increased,
- the invention provides that the resilient configuration of the clamping jaw is achieved by a weakening of the clamping jaw on the side facing away from the cutting element.
- the resilient configuration can also be adjusted by a suitable material selection or suitable component dimensioning.
- a recess designed as a groove is formed in the clamping jaw on the side facing away from the cutting element, for example by a separation method or by a appropriate design during the original molding process.
- multiple weakenings or recesses may be provided in the jaw. Due to the weakening of the clamping jaw on the side facing away from the cutting element, an "elastic joint" is created, whereby the clamping jaws resiliently bears against the cutting element and presses this into its seat in the receptacle of the supporting body.
- the weakenings or recesses extend over the entire axial width of the jaws or.
- a plurality of weakenings or recesses are provided, these are advantageously arranged substantially parallel to one another, however, the recesses or weakenings can also be adapted differently from a parallel orientation to adapt to certain cutting edge geometries or applications that cause a certain wear behavior.
- a spring element is arranged in the weakening or recess, which loads the clamping jaws so that a bias of the clamping jaw takes place in the direction of the cutting edge of the cutting element.
- the spring element is preferably made of an elastic material or a compression spring and causes an expansion of the weakening or the recess, so that an increase in the spring force in the upper and lower end region of the clamping jaw occurs.
- An inexpensive and effective embodiment of the recess or the weakening is a groove or a plurality of grooves which are incorporated in the clamping jaws.
- This groove can be adapted in shape and size to the particular application and easily incorporated by grinding or milling in the jaws.
- a corresponding configuration of the groove facilitates the arrangement of the spring element in the form of an elastic plastic or a compression spring, as is ensured by a corresponding cross-sectional design a secure attachment of the spring element to the clamping jaws in the groove.
- a further embodiment provides that the clamping jaws is designed bent in the direction of the cutting element and consists of a metal or plastic piece. This bending acts as a kind of bias and supports the resilient effect on the cutting element, whereby an increase in the contact pressure is effected in particular in the region of the cutting edge of the cutting element.
- a screw connection of the clamping jaw is provided with the support body.
- adjustability of the contact pressure is made possible in which the tightening torque of the screw can be varied and adjusted.
- different jaws can be used depending on the purpose, which is easy to implement by a detachable connection by means of screwing.
- a development provides that on the clamping jaw in the direction of the cutting element, a projection is arranged, which engages in a corresponding recess of the cutting element.
- the projection may also be arranged on the cutting element and engage in a recess of the clamping jaw.
- the projection and the recess are for axial and radial securing of the cutting element trained and support the definition of the cutting element in the seat of the support body.
- an axial securing element for the cutting element is provided on the supporting body in order to prevent a lateral displacement of the cutting element.
- a resilient design of the clamping jaw in the direction of the cutting element is provided that a resilient formation of the clamping jaw takes place in the direction of the cutting edge in order to obtain an optimal clamping of the cutting element and a precise guidance of the cutting edge.
- a development of the invention provides that in the cutting element an indicator recess, in particular an indicator groove is ground, indicating the end of a NachMrfzone.
- This makes it possible to equip the cutting tool with a resharpenable cutting element.
- the goal is to be able to transfer a high clamping force to the cutting element despite decreasing material thickness with repeated resharpening.
- an elastic clamping jaw only a precisely defined variation of the material thickness of the cutting element is permitted, since a sufficiently secure clamping of the cutting element and a sufficient precision in the adjustment of the cutting tool must be ensured.
- the permissible tolerances for the material thickness of the cutting element and thus for the depth of the Indikatorausappelung are extremely low, so that due to the low tolerances Grinding a grinding in a Indikatorausappelung, in particular an indicator groove, is an advantage.
- the cutting tool is designed as a knife shaft or a knife head of a woodworking machine, however, it is possible to use this cutting tool for metal, plastic or stone processing.
- the FIG. 1 shows a cutting tool with a support body 1 and a receptacle incorporated therein 2.
- the receptacle 2 may either be incorporated during the primary molding process of the support body 1 in the mold or subsequently by milling, grinding or another Machining methods are incorporated.
- the receptacle 2 serves as a seat for a cutting element 4, the cutting edge 3 extends radially outwardly from the support body 1 in the illustrated embodiment.

- a groove 6 is incorporated through which a weakening occurs due to the missing material, resulting in a joint effect in the region of the groove 6.
- a compression spring 8 is inserted, which presses apart the parts of the clamping jaw 5 on both sides of the groove 6 and so causes a resilient contact of the clamping jaw 5 on the cutting element 4, in particular in the region of the cutting edge 3.
- the compression spring 8 is shown schematically in the embodiment and stands for all compression spring elements that can widen the groove 6.
- the clamping jaw 5 is biased and curved so that the radially outwardly or inwardly facing ends of the clamping jaw 5 are resiliently biased.
- a projection 10 is formed, which engages in a corresponding groove 11 in the cutting element 4 and in addition to the force applied by the screw 9 clamping force a positive locking against a radial displacement of the cutting element 4 due forms centrifugal forces.
- FIG. 2 can be seen in an enlarged detail that the formed as a bolt axial securing element 12 is passed through a hole into the seat of the cutting element 4 in the receptacle 2.
- the clamping jaws 5 forms the other contact surface for the axial securing element 12, so that this is fixed in the assembled state.
- a recess 16 is incorporated, which is formed corresponding to the axial securing element 12 and in the assembled state, the axial securing element 12 comprises. In this way, a displacement of the cutting element 4 in the axial direction is prevented.
- the formation of the groove 6 in the clamping jaws 5 and the pressure spring 8 arranged within the groove 6 becomes clear.
- the groove 6 extends over the entire axial width of the clamping jaw 5, so that over the entire width of the clamping jaw 5, a spring action in the direction of the cutting edge 3 of the cutting element 4 can be effected.
- the recess 11 within the cutting element 4 engages in the mounted state in the projection 10 of the clamping jaw 5 and prevents radial displacement of the cutting element 4 during operation of the cutting tool.
- FIG. 3 the arrangement of the cutting element 4, the clamping jaw 5 and the support body 1 is clear, as well as the effect of arranged in the groove 6 compression spring 8.
- the compression spring 8 causes a widening of the groove 6 at the cutting element 4 facing away from the edges, as shown by the arrows D is shown.
- This pressure are radially seen the outer and inner ends of the clamping jaw 5 bent or biased in the direction of the cutting element 4, as indicated by the arrows B. This bias can also be introduced in the course of the manufacturing process.
- the receptacle 2 is formed at the radially inner end in such a way that a correspondingly shaped end of the clamping jaw 5 is easily pivoted, so that a rotation about this inner point is effected by the radially further outwardly disposed screw 9 and by means of the screw 9 applied tensile force , This way is a safe Clamping of the cutting element 4 ensured by the clamping jaws 5.
- the compression spring 8 presses the outer end of the clamping jaw 5 upwards and causes a rotation or bending of the upper portion of the clamping jaw 5 to the region of material weakening through the groove. 6
- FIGS. 5A to 10B show various representations of clamping jaws 5, wherein the marked by the reference numeral A in each case a sectional view and the figures designated by the reference numeral 8 are a sloping plan view.
- FIG. 5 is shown with a radially outwardly enlarged bevel 15 of the clamping jaw 5, with the corresponding after the installation of the clamping jaw 5 in the cutting tool a corresponding contact force on the cutting element 4 in the region of the cutting edge 3 is applied.
- the spring action of the clamping jaw 5 is effected by the reduction of the material in the radially outer end of the clamping jaw 5, so that a whip or leaf spring effect arises, through which an increase in the contact pressure force is achieved.
- the clamping jaw 5 can also be curved, in order in particular to increase the contact pressure on the inner and outer regions of the cutting element 4.
- the object of the FIG. 5 is not an embodiment of the invention.
- grooves 6 or a groove 6 are milled into the clamping jaw 5 over its entire axial width, in which an elastic spring element, for example an elastic plastic 7 is incorporated in order to achieve a corresponding spring effect.

- FIGS. 8 and 9 show a clamping jaws 5 with grooves 6 and a groove 6, wherein in the groove 6 in the grooves 6 no spring element is inserted.
- the joint effect or the spring action and a corresponding bias of the clamping jaw 5 can be reinforced, for example, via a corresponding surface treatment and voltage conditions generated thereby within the clamping jaw 5.
- FIG. 10 shows in detail a jaw 5 according to the FIGS. 1 to 4 with a arranged within the groove 6, shown schematically compression spring 8, whose operation in the FIGS. 1 to 4 is explained.
- FIG. 11 In plan view, a foot part of a cutting element 4 is shown with a recess 16 for receiving the axial securing element 12 without the cutting edge 3.
- a Indikatorausnaturalung 13 is ground in the form of a groove over the entire width of the cutting element 4 to indicate how far the cutting element 4 can be reground before the minimum material thickness is reached. Reprecipitation too often reduces the material thickness of the cutting element 4, which leads to a diminishing strength and problems with an exact and firm clamping in the cutting tool or support body 1 and impairs secure clamping by the clamping jaw 5.
- FIG. 11a the cutting element 4 is shown with its original material thickness, in the FIG. 11b in an already maximum reground state, which can be seen at the different depth of the recess 11.
- the depth of the indicator groove 13 is the measure for the regrinding zone 14, within which regrinding can be carried out without danger.
- the end of the regrinding zone has been reached.
- the safe use of the knives is guaranteed as long as a difference in thickness of the knives in the area of the clamping surface and the indicator groove 13 can be seen.
- the maximum re-sharpening zone is no longer detectable. These knives or cutting elements 4 could for the Clamping system have too small a knife thickness and may therefore no longer be used.
- the grinding in of the indicator groove 13 has the great advantage that an extraordinarily precise introduction of the recess or the groove 13 can take place.
- the recess may also have a different shape. If similarly precise methods can be provided, the indicator groove 13 can also be introduced into the cutting element 4 in a different manner.
- FIG. 12 a clamping jaws 5 is shown with a running over the entire width of the clamping jaws 5 groove 6, wherein the clamping jaws 5 at the same time has a chamfer 15, which leads to an increased elasticity and spring action.
- the groove 6 is formed with a rounded cross section, which opens in the direction of the clamping jaw surface and thus has a parabolic shape.
- FIG. 13 shows a similar construction of the jaw 5 as the FIG. 12 , but with a different contour of the groove 6, which is formed as a pitch circle, with a circumference of more than 180 °. As a result, an undercut is formed within the groove 6.
- FIG. 14 is a variant of FIG. 9 shown, in which the radially outer region of the clamping jaw 5 is provided with a weakening by a part of the material of the clamping jaw 5 has been removed. Also, the contour of the recess or groove 6 differs from that of the FIG. 9 , The groove shape 6 corresponds to the groove shape of FIG. 12 ,
- FIG. 15 is a jaw 5 without a spring element 8 according to the FIG. 10 shown.
- the recess 6 is not rounded, but executed at an angle. Instead of a rounded or formed by two bevels groove 6, this may also be polygonal. All jaws 5 point a threaded bore for receiving the bolt or the screw 9.
