    DK 2020 00073 U1 Form part for a procedure for sharpening a tool as well as arrangement with such a form part The present application claims the priority of the German patent->> report DE 10 2017 214 760.1, the contents of which are incorporated herein by reference. . The invention relates to a molded part for a process for sharpening a tool as well as to a device with such a molded part.
    When cutting a basic material, such as concrete drilling, the cutting edge of a tool is used. The tool becomes blunt. For further material processing it is necessary to sharpen the tool. Sharpening plates are used for sharpening concrete drill bits, which are known, for example, in DE 40 27 821 A1 in the form of healing beds of a transport container. The tool stretches the sharpening plate, which is made of a sharpening material, which sharpens the cuts of the tool. The use of sharpening plates is expensive - and leads to a longer interruption of material processing. The sharpening of the tool on the sharpening plate is inefficient, as parts of the sharpening plate break out and are not usable for sharpening. The material yield of the shear material is constrained.
    EP 1 428 623 B1 discloses a sharpening agent for drill bits, which is rigidly shaped and can be inserted into a circular ring gap. DE 602 08 602 T2 discloses an abrasive which is applied particulate through the drill bit of the machining surface.
    The object of the invention is to improve the sharpening of a tool, in particular to make it more uncomplicated and efficient.
    The task is solved by the features of claims 1 and 4. The core of the invention consists in that a molded part of a sharp material is arranged on a machining surface of a basic material which is machined with a tool. Several molding parts can also be arranged on the machining surface. The mold part is also referred to as a sharp mold part. As processing continues, the molded part is clamped by the tool, thereby sharpening the tool, especially automatic and especially automatic. The tool can be stationary or mobile. The self-sharpening of the tool is simplified. A separate sharpening plate is - indispensable. The material yield of the sharpening material is increased, as the mold part for sharpening the tool is completely stretched. A loss of material does not occur. Due to the fact that the sharpening process takes place immediately on the basic material, the failure time of the tool is reduced. A tool change can be avoided. The load on the tool is increased. The economics of material processing is increased.
    The tool is especially a separating tool, especially for the exciting machining of a basic material. Tools are, for example,> diamond tools or similar, in particular diamond-studded drill bits, hollow drills and / or full drills for all current drilling diameters. The tool is especially suitable for dry drilling in stone-based material, especially concrete, reinforced concrete, masonry, asphalt or the like, and / or in metal-based material, especially
    DK 2020 00073 U1 -3- Steel, iron or similar. The tool can also be used for wet drilling in the mentioned materials. The tool can be made in the form of a disc, especially as a diamond-studded saw blade or wall saw blade or joint cutting blade for construction saws, table saws or the like, as a separating disc for all tools, especially stone, various types of concrete, glass, metal. The disc-shaped tool is made in particular in one of the current blade diameters.
    The tool can also be a grinding or polishing disc, which is ceramic-bonded, metal-bonded and / or resin-bonded. The tool can also be designed linearly as a diamond-studded rope, sword or chainsaw or the like for concrete, reinforced concrete and other stone-based materials or metal materials, in particular steel, iron or the like. The tool can also be a granite saw or slatted saw, which is used for machining rock and / or wood.
    A chainsaw can be used for machining wood or plastic material. A tool can also be a disc, in particular a disc with diamond tools for polishing and / or grinding. The tool can also be a space tool. The tool can be used for soil treatment in reinforced concrete or similar material.
    DK 2020 00073 U1 -4- A procedure in which a production of a deepening in the base material with the tool along a deepening direction, a removal of the tool from the deepening, an insertion of at least one mold part into the deepening and a re-feeding of the tool in the deepening occurs, an increased process security allows. The molded part is arranged in particular in such a way that the molded part appears in the longitudinal direction of the tool, i.e. along a deepening direction, at least axially and / or radially on the tool. It is advantageous if the mold part is axial to the tool. The molded part is used in particular to sharpen the vocal surfaces of the tool, in particular the star surfaces of the cutting tool.
    The tool produces a deepening in the base material. The deepening extends along a deepening direction. At least one form part, in particular together with the tool, is immediately inserted into the recess. After the re-introduction of the tool and the continuation of the machining, the molded part is clamped in - the recess. The sharpening of the tool is improved. Immediate fixation of the mold part is indispensable, as the mold part is held in the recess. In particular, the form part in the distribution itself is kept. The sharpening process takes place immediately in the distribution. The procedure is error-free.
    The application of the molded part to the tool prior to use in the deepening ensures a defined sharpening process. The mold part can protrude in the axial direction of the tool. The form part comes with the
    DK 2020 00073 U1 -5- Tool common and defined introduced in the deepening. The molded part is defined in relation to the tool. An inventive component simplifies the process of sharpening the tool. Due to the fact that the molded part has sharp material and in particular consists of a sharp material, an automatic sharpening of the tool during material processing in the deepening is ensured.
    The mold part ensures in particular the reliable sharpening of various tool materials. Silicon carbide (SiC) and / or corundum or the like are suitable for sharpening diamond-studded cuts.
    Ein formteil gemåbB Claim 2 is particularly suitable for an annular depression, which is produced in particular by a drill bit. Form part sets with hollow cylinders or cylinder shell segments can be provided with different diameters, which are adapted to the diameters of the drill bits. Cylindrical shell segment moldings can be immediately attached to the tool, particularly glued, stitched, tensioned, clicked or welded. The cylinder shell segments are specially designed as half shells, ie with an opening angle of 180 ° with respect to the cylinder longitudinal axis. There are also other opening angles, in particular 120 ° or 90% possible.
    Ein formteil gemåB Claim 3 allows for an advantageous application on the tool and / or in the recess. A conical or conical blunt-shaped part can be made in the shape of a thimble and can be mounted directly on a drill. A wedge-shaped
    DK 2020 00073 U1 - 6- Form part can be used immediately in the recess, whereby due to the wedge shape a self-clamping of the form part in the recess is ensured.
    Rod-shaped or rod-shaped moldings can be used along the extent of an annular recess.
    The rod-shaped or rod-shaped form elements can also be used in a depression with a circular or nut-shaped cross-sectional area.
    The molded parts can also be made plate-shaped.
    Advantageously, it is possible to make the molded parts, in particular the plate-shaped molded parts, as a frangible plate of a table for disposal, similar to a chocolate table.
    A target break notch can be provided between two adjacent plates.
    If needed, a plate can be broken off the table.
    Eine Anordnung gemåB Anspruch 5 enables an uncomplicated tension.
    An arrangement according to claim 6 enables the immediate use of the molded part.
    A nut-shaped cross-sectional area of the depression is produced, for example, by a sieve, a chain or a rope.
    A circular depression is produced by a full drill.
    An annular depression is produced by means of a drill bit.
    A tool with at least one cut, which is particularly diamond-studded, can be advantageously sharpened.
    It is advantageous if the mold part is attached to the tool before being inserted into the recess.
    The attachment can be a fixation, for example by gluing.
    The attachment of the form part to the work
    DK 2020 00073 U1 -7- can also be done by sticking up, clipping, clipping, rusting and / or clamping, especially in the circumferential direction on a drill bit.
    For example, the molded part may have protrusions which correspond to the eruptions of the drill bit, so that the molded part is fixed to the tool in at least one eruption of the tool, in particular in the circumferential direction, i.e. tangential. Additionally or alternatively, the molded part may have clamped projections which cause a clamping holder of the molded part to be cut during cutting of the tool. In particular, the molded part can be made in such a way that it has an axially projecting section on the tool, whereby this section is designed as a hollow cylinder, which in particular has an identical diameter as the tool itself, thus identifying and otherwise identical.
    It is advantageous if at least one molded part is attached to the tool before it is inserted into the recess, so that the molded part can be used in particular with overhead recesses. An Uber-head deepening is then given when a deepening direction is at least partly vertically upwards and in particular exclusively vertically upwards. Drill meal can deflect from the recess due to the direction of gravity due to gravity.
    The immediate insertion of a mold part into the recess is uncomplicated. The form part can be used quickly and error-free in the distribution. It is advantageous if the molded part is made in such a way that it is clamped in the recess. An unintentional
    DK 2020 00073 U1 -8- slip, in particular a failure of the mold part from the deepening, is prevented.
    Further advantageous features, additional features and details of the invention will be apparent from the following description of exemplary embodiments taken in conjunction with the accompanying drawings.
    It shows: FIG. 1 is a sectional view of a device with a tool cut section line I - I in FIG. 7 and a basic material before the start of material processing, fig. 2 a fig. 1 according to the representation after the production of a depression in the basic material, fig. 3 a fig. 2 according to the removal of the tool from the recess, fig. 4 a fig. 3 corresponding representation with molded parts mounted on the tool,

    The following is based on FIG. 1 to 7 a tool 1 and a procedure for sharpening tool 1 are explained in more detail. Tool I is essentially hollow-cylindrical with respect to a tool longitudinal axis 2. Tool 1 is a drill bit that can be used especially for concrete or wet drilling.
    - In a front machining star surface 3, the tool 1 shows several cylindrical shell segment-shaped cuts 4, based on the exemplary embodiment shown. The cuts 4 are arranged in the same way along the circumference of the tool 1. Two cuts 4, respectively, are arranged diametrically opposite one another relative to the tool longitudinal axis 2. The cuts 4 are star-side, diamond-studded on their inner surface and / or on their outer surface, in order to improve the tension of the base material 9. An outbreak 5 is provided between two adjacent cuttings 4, in order to demand special drilling flour into the inside of the drilling crown.
    DK 2020 00073 U1 - 10- On one of the machining star surfaces 3 opposite rear star surfaces 6, the tool 1 indicates a torque transmission continuation 7. The torque transmission continuation 7 points in an plane - perpendicular to the tool longitudinal axis 2 to an unrounded contour, in particular an unrounded bevel contour, in particular an auxiliary hexagon edge, in order to provide a driving torque of the tool machine to the tool machine.
    The tool 1 shows a hollow cylindrical basic body 8. The cuttings 4 are connected to the base body 8 on one side of the machining star surface 3.
    The following is based on FIG. 1 to 6 a procedure for sharpening the tool I is explained in more detail. Får die Schnittdarstellungen gemåB Fig. 1 to 6, a cutting plane bending at the tool longitudinal axis 2 was chosen to indicate both the cut 4 and the outbreak 5.
    The tool 1 is, as in FIG. 1, positioned opposite the base material 9 to be machined. According to the exemplary embodiment shown, the basic material is 9 concrete.
    The tool 1 is rotated relative to the tool longitudinal axis 2 and displaced along a deepening direction 10 relative to the base material 9. By means of the cutting 4, a depression 11 is formed in the base material 9, in which the base material 9 is stretched. According to the exemplary embodiment shown, the depression 11 extends from a surface 12 of the base material 9 along the depth direction 10 to the first depth Ti, as shown in FIG. 2 presented. The First Depth T1
    DK 2020 00073 U1 -11- indicates the distance of the base of the depression 11 along the tool longitudinal axis 2 to the surface 12 of the base material 9. The direction of distribution 10 is oriented parallel to the tool longitudinal axis 2. At a level perpendicular to the direction of depression 10, the depression 11 is ring-shaped. Due to the strenuous processing of the base material 9, the cuts 4 wear out and become blunt. The tool 1 is, as in FIG. 3, taken from the deepening opposite the deepening direction 10.
    At least one mold part 13 is fitted to the tool 8. In accordance with the exemplary embodiment shown, several, in particular eight, form parts 13 are used, which are arranged in the breaks 5 between the cuts 4, respectively. This is shown in FIG. 4 represented. According to the exemplary embodiment shown, the molded parts 13 are glued to the tool I. The molded parts 13 are fixed to the tool 1, i.e. defined.
    The mold part 13 is designed as a cylinder shell segment. According to the exemplary embodiment shown, the mold parts 13 on the machining star surface 3 are finely executed with the cuts 4. It is also conceivable that the molded parts 13 are arranged on the machining star surface 3 or arranged backwards.
    The molded parts 13 are made of a sharpening material which, according to the illustrated embodiment, shows silicon carbide.
    DK 2020 00073 U1 -12- The tool 1 with the molded parts 13 attached to it is reintroduced into the recess 11. This is shown in FIG. 5 presented. The tension with the tool 1 is continued. Due to the tool movement, the mold part 13 is broken out and / or stretched. Due to the contact of the cutting 4 with the sharpening material of the mold part 13, a sharpening, in particular a self-tapping sharpening of the cutting 4 of the tool 1 in the recess 11 is effected. The tool 1 can be used immediately and in particular without further removal from the depression 11 for further material processing, in order to continue the depression 11 up to a second depth T. When the cuts 4 of the tool 1 are blunt again, the self-tapping sharpening step is repeated by removing the tool 1 from the recess 11, using at least one mold part 13 and repeating the further processing with the sharpening. The self-tapping sharpening is often repeated. In the following, with reference to FIG. 8 to 10 further embodiments of tools and molded parts.
    FIG. 8 shows a drop view of the depression 11, FIG. 3. Instead of mold parts 13, which are arranged on the tool 1, rod-shaped mold parts 14 can be introduced into the distribution 11 along the direction of deepening 10. It is advantageous if the length of the form parts 14 is smaller than the first depth T1. According to the illustrated embodiment, the mold parts 14 have a circular cross section perpendicular to the mold longitudinal axis. The shaped parts 14 can also have an unrounded, for example polygonal cross-section.
    DK 2020 00073 U1 -13- It is also conceivable to use the rod-shaped molded parts 14 to insert a hollow-cylindrical, in particular annular molded part into the recess 11 along the deepening direction 10. Such a molded part can also be divided into cylindrical half-shells or be divided into several parts.
    FIG. 9 shows a useful depression 15. The depression 15 is designed as a right angle. Depending on the geometry of the tool, the recess 15 in the nut base 16 may also have curves. The direction of distribution is similar to FIG. 9 essentially oriented perpendicular to the plane of the sign. The recess 15 is produced, for example, by a saw blade or a cutting disc. The saw blade is moved relative to the base material 9 along the deepening direction. To sharpen the tool, a wedge-shaped mold part 17 is provided, which is clamped on the nut flanks 18 of the recess 15. The mold part 17 is reliably held in the recess 15. The geometry of the mold part 17, in particular the opening angle of the wedge arranged in the recess 15, the length of the wedge and the resistance of the wedge opposite the surface 12 of the recess 15, is variable. According to the exemplary embodiment shown, the mold part 17 on the surface 12 protrudes. The mold part 17 can also be selected in such a way that it closes completely with the surface 12 or is moved into the recess 15 opposite to the surface 12. FIG. 10 shows a further embodiment with a tool 19 designed as a full drill. To sharpen the tool 19, a finger-shaped mold part 20 is mounted on the drill bit tip.
