Definitions
- the invention relates to a knife holder for a knife tool head which can be equipped with circumferential chopping knives and face plan knives, the knife holder having a mounting surface for a chopping knife and an adjacent mounting surface inclined against it for a plan knife, and knife fastening means for releasably fastening the chopping knife and the plan knife has on the respective mounting surface, on an associated knife and on a knife tool head with a frustoconical or cylindrical base body and a plurality of knife holders fastened thereon, on each of which one or more knives are held.
- Knife tool heads of this type are used, for example, for cutting wood, in particular for cutting the lateral segments of logs in profile cutters and choppers in the production of paper chips.
- the chopping knives are primarily used to produce the chips, the plan knives, also called finishing knives, primarily to achieve a smooth, flat surface of the remaining wood material.
- the carrier is first screwed to the mounting surface of the holder, then the chopper or plan knife is placed on it, and then the clamping piece is placed and screwed to the holder at fastening points on the side next to the knife, the screws reaching through through holes in the carrier.
- the published patent application DE 198 16 164 A1 discloses a further generic knife holder, in which chopping and planing knives are clamped to the holder in the same way using a clamping piece and a carrier.
- the knife holder there has a dovetail-shaped flange with which it can be fixed to a hub element which functions as the base body of the tool head.
- the ring-cylindrical hub element on the outer casing has flattened areas with longitudinal grooves, into each of which a knife holder with its flange can be axially inserted and then fixed.
- the chopping and planing knives of the turning knife type used in the generic knife holders mentioned above are of rectangular basic shape, ie their transverse or narrow sides run in planes perpendicular to the longitudinal edge knife edges.
- the cleaver and plan knife In applications in which the longitudinal axes of the cleaver and plan knife lie in different planes, i.e. in which the cleaver precedes or lags the plan knife in the direction of rotation of the tool head, the cleaver and plan knife only limit the new, active ends with their facing ends Knife cutting together.
- the invention is based on the technical problem of providing a knife holder of the type mentioned at the outset, a knife therefor and an associated knife tool head, which enable safe, play-free and self-centering holding of a cleaver and a plan knife together on a holder which in turn can be fastened to the tool head , and which allow a relatively simple replacement of the knives without complex adjustment work, the cleaver and plan knife being able to be mounted on the holder with closely adjoining knife edges even when re-sharpened.
- the invention solves this problem by providing a knife holder with the features of claim 1 or 2, a knife with the features of claim 7 and a knife tool head with the features of claim 8.
- both mounting surfaces for the chopping knife and the plan knife each have cross-sectionally V-shaped holder contact surfaces, and direct fastening means are provided as the knife fastening means, which Fix the cleaver and the plan knife, each of which has a corresponding V-shaped inclined blade contact surface, directly to the respective holder contact surface with a holding force acting between the V-shaped inclined contact surfaces.
- the line of action of the holding force for both the chopping knife and the plan knife lies in the angular range spanned by the V-shaped contact surfaces, so that the action of the holding force results in the self-centering of both knives when they are fixed on the knife holder.
- the centered position is clearly defined for each of the two knives by the pairs of interacting, V-shaped inclined contact surfaces opposite each other with respect to the line of action of the holding force.
- the holding force acting in this way also results in an even distribution of forces on these contact surfaces and thus overall in a favorable, uniform fastening force action on the respective knife and the knife holder.
- cleaver and plan knife are fixed directly to the respective mounting surface, and the holder body is designed as a one-piece component and in turn can be attached directly to the knife tool head.
- the direct fastening means each consist of a single screw connection for the plan knife and one or two screw connections for the cleaver.
- no further fastening components, such as clamping pieces or the like, are required.
- holder fastening means are provided for the knife holder laterally next to the mounting surfaces for the knives.
- the knife according to the invention is designed in such a way that it has one or two inclined contact areas on at least one transverse side, which extend from a knife edge with a bevel that corresponds to a corresponding bevel angle of the relative position of the circumferential knife and plan knife on the holder, so that the knife, when it is mounted on the holder as a cleaver or plan knife, not only adjoins the other knife in a point-like manner, but with this area in a line or area.
- Chopping and planing knives can be provided with appropriate bevels, or the bevel is formed entirely on one knife, the other knife then having a transverse edge perpendicular to the knife edge.
- a plurality of knife holders according to the invention are arranged distributed around the circumference of a frustoconical base body. They are used in the associated holder receptacles, with the cleavers pointing to the basic body truncated cone and the facing knives to the front of the basic body.
- a plurality of second knife holders are provided on the main body truncated cone of the tool head behind said knife holders according to the invention, each of which is equipped with a cleaver and a plan knife, and offset with respect to these in the circumferential direction, the second knife holder only are equipped with a cleaver.
- the knife tool head is equipped with two different types of knife holders according to the invention, which differ by chopping knives of different lengths.
- the two different types of knife holder are arranged in the circumferential direction of the tool head base body in a predeterminable regular sequence.
- a knife tool of this type very well fulfills the functions of chip removal and simultaneous finishing that it desires.
- plan knives of two or more are successively in the direction of rotation Tool head mounted knife holders with plan and chopping knives arranged in axially offset planes. This enables a specific, desired chip thickness to be achieved in accordance with the axial distance between such successive planing knives.

- the knife holder consists of a one-piece solid metallic holder body 1 of the shape resulting from FIGS. 1 to 3.
- 1 and 2 includes a smaller first surface area 2 and a larger second surface area 3 that is inclined relative thereto.
- a left part of the first surface area 2 in FIGS. 1 and 2 is designed as a mounting surface 4 on which a plan knife 5 is mounted.
- a part of the second surface area 3 on the left in FIGS. 1 and 2 is designed as a mounting surface 6 which adjoins the mounting surface 4 and on which a cleaver 7 is mounted.
- plan and chopping knives 5, 7, reversible knives are used, each with two opposing cutting edges 5a, 5b and 7a, 7b, the planing knife 5 having a rectangular basic shape with transverse sides 30, 31 perpendicular to the longitudinal knife edges 5a, 5b, and so on Holder body 1 is positioned that it lies with its knife level largely parallel to the end face of the tool head when the holder body 1 is attached to the tool head.
- the cleaver 7, too Circumferential knife extends with its knife plane essentially on the circumference of the tool head when the holder body 1 is mounted on the tool head. It has an elongated, essentially rectangular basic shape, but it is bevelled at its four corner areas on transverse sides 32, 33 over a certain extent adjacent to the cutting edges 7a, 7b, with the formation of corresponding flat contact areas 34 to 37.
- the two knives 5, 7 lie face to face with their free, effective knife edges 5a, 7a or in any case at a very short distance from one another. Chips detached during operation from these knife edges 5a, 7a can be discharged via the subsequent side 8 of the holder body 1, which acts as a deflector.
- the angle information in the two different views in two mutually perpendicular directions according to FIGS. 2 and 3 clarify the mutual spatial position of plan knife 5 and cleaver 7, in particular the mutual spatial position of their effective, free cutting edges 5a, 7a.
- FIG. 2 and 3 clarify the mutual spatial position of plan knife 5 and cleaver 7, in particular the mutual spatial position of their effective, free cutting edges 5a, 7a.
- the effective cutting edges 5a, 7a of plan knife 5 and chopping knife 7 enclose an angle ⁇ , which in the example shown is approximately 159 ° and which in alternative exemplary embodiments depends on Can have a different value between 130 ° and 230 °.
- This angle ⁇ determines whether and to what extent the chopping knife 7 leads or lags the planing knife 5 in the direction of rotation of the tool head.
- the angle ⁇ drawn in a projection view parallel to the chopping knife plane in FIG. 3 indicates how steep the chopping knife is with respect to the plane knife plane and thus the end face of the tool head.
- the angle ⁇ is approximately 135 °, in alternative exemplary embodiments it can assume values between 80 ° and 180 ° as required.
- the plan knife 5 is detachably fastened to the plan knife mounting surface 4 of the holder body 1 by means of a single, central screw connection 9.
- the plan knife mounting surface 4 of the holder body 1 has a profile with two holder contact surfaces inclined in a V-shaped cross section, against which the plan knife 5 rests with two corresponding knife contact surfaces inclined in a V-shaped manner, as is shown below for the exemplary embodiment of FIGS 7 is explained in more detail.
- the V-shaped holder contact surfaces and knife contact surfaces inclined towards each other each enclose an angle of preferably less than 130 °, for example of approximately 110 °.
- V-angle enclosed by the V-shaped inclined knife contact surfaces is preferably somewhat smaller than the V-angle enclosed by the holder contact surfaces, so that the face knife with its contact surfaces Chen first comes to rest against the mounting surface 4 and then is pressed under the action of the fastening screw 9 into the V-shaped receptacle formed by the contact surfaces of this mounting surface 4, primarily at the outer end regions of the V flanks.
- the cleaver 7 is fixed by means of two fastening screws 10, 11 on the associated mounting surface 6 of the holder body 1, which has a profiling with two holder contact surfaces inclined in a V-shaped cross section, against the corresponding V-shaped inclined knife contact surfaces formed on the back of the cleaver centering.
- the V-profiles run in the longitudinal direction of the knife 5 and the cleaver 7, i.e. parallel to the knife edges 5a, 7a.
- the fastening screws and thus the lines of action of these fastening means extend between the respective pair of V-contact surfaces, so that self-centering and evenly distributed holding forces are exerted on the plan knife 5 and the cleaver 7 by the screw connections 9, 10, 11.
- the holder body 1 In its right section in FIGS. 1 and 2 in addition to the mounting surfaces 4, 6 for the knife attachment, the holder body 1 is provided with two through bores 12, 13, each of which is introduced approximately perpendicular to the plane of the plane in the holder body 1, the. a bore 12 is located in the first surface area 2 and the second bore 13 in the second surface area 3. These bores 12, 13 together with associated fastening screws (not shown) form holder fastening means in order to fix the holder body 1 directly on the tool head. This enables a very simple fastening of the holder to the tool head with only two screws without being hindered by the plan knife 5 and the cleaver 7 and without one of the knives 5, 7 having to be dismantled when the holder is on Tool head is assembled or disassembled.
- a different type of contact between the holder body 1 and the respective knife 5, 7 can be provided, while maintaining a direct attachment of a cleaver and a plan knife to an integral holder body, which in turn is attached directly to the knife tool head.
- FIGS. 4 to 8 illustrate a knife holder with a one-piece holder body 14, which largely corresponds to that of FIGS. 1 to 3, but in contrast to this is designed for a left-turning cutting tool head, and associated knives.
- the same plan knives 5 and similar chopping knives 7, 7 ' can be used for both knife holders, and for the sake of clarity the same reference numerals are used for functionally corresponding elements.
- FIG. 4 shows an end view of the planer knife 5 of the reversible knife type which can be used for the two knife holders, each with a knife edge 5a, 5b along the two longitudinal sides of the knife. 4 shows the two V-shaped knife contact surfaces 5c, 5d on the back of the knife, which, as explained above, form the contact surfaces of the facing knife 5 when mounted on the holder body 1, 14.
- Fig. 5 shows the holder body 14 with the knives removed in a to.
- Plan knife end view of FIG. 4 parallel direction, ie parallel to the plan knife longitudinal axis or the knife edges 5a, 5b when the plan knife 5 is mounted.
- 6 shows the corresponding view with the plan knife 5 mounted.
- the corresponding V-shaped holder contact surfaces 14a, 14b can be clearly seen, which are formed by appropriate profiling of the plan knife mounting surface 4 of the holder body 14 and against which the self-centering face knife with its V-contact surfaces 5c, 5d can be placed, as explained above for the embodiment of FIGS. 1 to 3.
- FIG. 5 shows the holder body 14 with the knives removed in a to.
- Plan knife end view of FIG. 4 parallel direction, ie parallel to the plan knife longitudinal axis or the knife edges 5a, 5b when the plan knife 5 is mounted.
- 6 shows the corresponding view with the plan knife 5 mounted.
- the corresponding V-shaped holder contact surfaces 14a, 14b can be clearly seen
- V-holder contact surfaces 14a, 14b end inwards in a trough-shaped recess 15 and outwards in a shoulder 16a, 16b.
- projections 17a, 17b on the knife side overlap the holder-side shoulders 16a, 16b in a centering and position-securing manner, as can be seen in FIG. 6.
- the face knife 5 is also held in this example by a single, central fastening screw on the holder body 14, which extends in the area between the knife-side and holder-side contact surfaces 5c, 5d, 14a, 14b through a central bore in the face knife 5 and into which Holder body 14 is screwed into the trough area 15 between the two holder-side V-contact surfaces 14a, 14b.
- a chopping knife T as shown in plan views of the top and bottom in FIGS. 7 and 8, can be mounted on the chopping knife mounting surface 6 of the holder body 14, as in an associated front view of FIG. 9 recognize and explained above for the largely identical embodiment of FIGS. 1 to 3.
- the chopping knife mounting surface 6 of the holder body 14 has a profile with two V-shaped holder contact surfaces 14c, 14d against which two corresponding V-shaped knife contact surfaces 7c, 7d can be applied self-centering.
- the chopping knife 7 ' is also of the turning knife type with two longitudinal cutters 7a, 7b and largely corresponds in its design to that of FIGS. 1 to 3. In contrast to the latter, the chopping knife 7' is full-area on its two transverse sides 38, 39 beveled, as the top view of FIG. 7 and the bottom view of FIG. 8 show.
- each transverse side 38, 39 is formed with an inclined surface 38a, 38b, 39a, 39b and one on the underside inclined surface 38c, 38d, 39c, 39d, the inclined surfaces 38a to 39d each extending outwards from the longitudinal center to the associated end of the knife edge and from the underside or top of the knife to the height of the knife edge plane where they meet.
- the inclined surfaces 38a, 38b, 39a, 39b on the underside act as potential contact surfaces, that is to say when the cleaver 7 'is mounted, it lies with the contact surface over the entire surface of the planer knife 5 which faces the planer knife 5 and the active cleaver knife 7a.
- the chopping knife T rests on the plan knife 5 virtually without gaps up to the level of its longitudinal center.
- the advantages explained above for the exemplary embodiment in FIGS. 1 to 3 of such a not only point-shaped, but at least linear and in this example even comparatively large-area installation of cleaver and plan knife on their active knife-edge side therefore apply to the example of FIGS. 4 to 9 to a special degree.
- the beveling of the knives realized in the shown areas on the chopping knife alone, which leads to the linear or planar abutting of both knives on the holder, can be provided on the plan knife instead of on the chopping knife.
- the bevel can be distributed over both knives, i.e. Chopping knives and planing knives are provided with corresponding bevels in this area, with which they adjoin one another in a linear or planar manner after installation on the holder.
- the chopping knife is fastened by means of two fastening screws which are arranged in the center and in Guide the knife in the longitudinal direction at a distance through the chopping knife T and are screwed into threaded bores which are introduced into the holder body 14 in the trough region between the holder contact surfaces 14c, 14d and of which a threaded hole 18 can be seen in FIG. 9.
- the two holder mounting holes 12, 13 can be seen on the back in FIG. 9, which are located in the holder halves to the side next to the mounting surfaces 4, 6 for plan knife 5 and cleaver T and serve to receive two fastening screws with which the holder body 14 directly on an example frustoconical base body of the knife tool head can be detachably attached without hindrance by the two mounted knives 5, 7 '.
- Two blind bores 19, 20 serve as centering holes for fastening the holder to the main body of the tool head.
- 10 and 11 show two application examples of the knife holder according to the invention.
- 10 shows a left-turning cutting tool head 21 with a frustoconical base body 22, into which receptacles 23 are introduced, distributed around the circumference, adjacent to the end face, into each of which a knife holder 24a, 24b is inserted.
- Two different types of knife holders 24a, 24b are used, each carrying a plan knife 5 and a cleaver 7 ', 7 ", the cleaver 7', 7" differing in length.
- One type of knife holder 24a essentially corresponds to the knife holder of FIGS. 4 to 7 with the face knife 5 and the circumferential chopping knife 7 ', the other holder type 24b has the same knife 5, but a shorter knife 7 "approximately the length of the knife 5.
- Fig. 11 shows a right-hand cutting knife tool head 25 with a frustoconical base body 26 which is provided on the circumference adjacent to its end face with recesses 27, in which knife holders of the type of the knife holder with the holder body 1 of FIGS. 1 to 3 are inserted.
- the face knives 5 face the end face of the tool head 25, the cleaver 7 'face the truncated cone jacket of the base body 26.
- knife holders 1 are arranged on the base body 26 evenly distributed over the circumference in this example. Axially behind it, a second row of six knife holders 28 is provided in the circumferential direction, which are mounted in associated receptacles 29 on the truncated cone jacket of the base body 25. These knife holders 28 are arranged offset in the circumferential direction in the center with respect to the front knife holders 1. In other words, there is an axially rear knife holder 28 in the circumferential direction between each two axially front knife holders 1 in the middle.
- the rear knife holders 28 are each equipped with only one chopping knife 7 'which corresponds to the chopping knives 7' of the front knife holder 1 in shape and type of fastening.
- the tool head 25 of FIG. 11 is particularly suitable for larger machining depths beyond that.
- the greater cutting depth is provided by the rear knife holder 28, which is attached to the circumference and each of which only carries the cleaver 7 '.
- the cutting tool tool heads shown in FIGS. 10 and 11 fulfill the desired cutting and finishing function very well.
- the knife holders can be easily mounted on and removed from the tool head base body.
- the plan knives and the cleaver are each very easily mountable and detachable from their holders, as explained above.
- Both the knives and the holder are fastened by direct fastening means, preferably screws, without additional clamping elements, which enables a secure hold and a very compact structure.
- the cleaver is designed so that it can be used on both sides, i.e. on a right-handed and a left-handed knife tool head.
- the knife holders are particularly suitable for attaching to conical or disc-shaped milling or chipping heads in wood processing.
- the chipper heads can be designed so that the knife holders are arranged in different stages from the flat surface in order to produce a defined chip thickness. These levels cover the area of the most common cutting depths. Greater cutting depths are then achieved with a knife holder with a long chopping knife, whereby the chip thickness is rather random. However, this case does not often occur with the correct design of the tool head and therefore influences the quality of the wood chips not significant. It goes without saying that the invention is not only suitable for machining wood processing, but also for all other areas of application of knife tool heads.
- the chopping and planing knives can be directly mounted together on a preferably one-piece holder body, for example by abutment with the V-shaped contact surfaces, and the holder body in turn can preferably be fastened directly to the knife tool head.
