Definitions
- the invention relates to sintered metal-bonded, abrasive segments containing hard material particles for tools for machining or cutting hard and / or brittle materials with one of the segments Tool carriers, each segment consisting of individual segment modules, whose structure is different, is composed (see e.g. WO-A-9 858 770).
- Abrasive segments for tools are used for machining or Cutting materials, for example in the form of cutting segments for Drill bits, cutters, chainsaws, saw blades, cut-off wheels, Hollow drills, scraper bars, or in the form of hollow beads for wire saws needed.
- a cutting tool is already known from EP 0 540 566 B1, in which the individual cutting segments over their length in their structure change monotonously, d. H. the abrasive grain quality and / or the abrasive grain concentration changes monotonously. This can be done by training the Cutting segment from a single piece or through The cutting segment is composed of several parts. in the the latter case then takes z. B. the abrasive grain concentration from part to part viewed monotonously in one direction.
- the cutting segment according to US 5,518,443 is also made in one piece and has a high manufacturing cost due to the different Hard material concentrations in the different areas.
- the invention has for its object the variety of required Forming tool segments containing hard material particles, especially very hard like diamonds or cubic boron nitride, in one rational way, and both the manufacture and the Warehousing this way is more economical and the costs to reduce. Another concern is to improve tool performance increase, d. H. to enable an optimal use of the hard material particles, as well as more wear-resistant segments, d. H. with increased lifespan too create.
- the sintered metal-bonded abrasive segments are constructed from individual segment modules of the same design and the segment modules are manufactured by hot isostatic pressing and the segments in the direction of movement of the segment in the front area starting from the contact edge to the rear area the segment is composed of segment modules with alternating concentrations of hard material particles and / or segment modules with areas alternating perpendicular to the direction of movement of the segment with alternating concentrations of hard material particles.
- the segment modules can have the same or different shape and the same composition of the sintered metal materials and / or the hard material particles or different compositions of the sintered metal materials and / or the hard material particles both in terms of quality and quantity.
- the invention describes a modular and graded structure sintered metal bonded abrasive segments for tools for Machining or cutting of materials. This is according to the invention also a sawtooth effect due to the alternating concentrations Hard material particles reached.
- segment modules are sufficient to a wide variety of different segments in terms of shape and Quality by mixing, combining and arranging the same and / or to generate different segment modules.
- FIG. 1 shows an example of a diamond tool in the form of a Saw disc shown, with a tool holder W made of metal, the Has circumferentially spaced cooling slots B and. between two each Cooling slots an inserted segment designed as a cutting segment SS has.
- These segments SS are usually used for saw discs made of sintered metal with embedded hard materials, preferably diamond grains each in one piece, d. H. made in one piece. The production these segments take place in a pressing process, with a green body in Graphite forms are clamped and by means of pressure and temperature is sintered to obtain the segment. According to the required different sizes and qualities - more or Less diamond grain content - on the one hand, there are a correspondingly large number Press molds required and appropriate storage of the individual different segments for different sizes and qualities of Saw blades.
- An exemplary typical segment for a saw blade is the Dimensions 40 x 3.6 x 7 mm with a radius of 225 mm and will on a 450 mm diameter saw blade disc - tool carrier W - for cutting concrete, natural stone, artificial stone, ceramic and asphalt fixed by soldering or laser welding or direct sintering.
- d. H Execution of the segments in at least 2 different qualities.
- At least 33 are common different radii of the saw blade discs, tool carrier. in addition come with at least 4 variants of the segments, namely "without foot, with Base, sandwich type, sloping or protective segment, conical segments, Roof segments, bendable and slotted segments ". This combination of all characteristics results in 1 848 different segments, which can be found in the Reduce practice through non-common combinations. This becomes can see what variety and therefore the need for stocking for the Manufacturers and thus costs arise.
- the saw blade is in the Shown detail that is modular with the trained according to the invention constructed segments Sm is equipped, each segment Sm from a plurality of segment modules M is composed.
- Such one typical cutting segment for a saw blade disc according to the invention in any number of small segment modules M, z. B. same Design and size and the possibility of different Composition, e.g. different hard material contents, see Figure 3, subdivided and in this way an additional variety is offered Variation options for assembling and building up segments different size and quality, whereby a strong reduction of the individual to be stored Segment types is achieved. Few basic types of segment modules suffice to mix and match a wide variety of segments and order to generate. It has not yet been possible to produce it new qualities.
- Each segment module can be characterized by the properties mentioned above characterize as follows: M (F, K, B, Q, V)
- Segment modules vary as follows: M1 (F1, K1, B1, Q1); M2 (F1, K2, B1, Q1); M3 (F1, K3, B1, Q1) or M4 (F1, K1, B1, Q2) etc.
- Cubes F1 for example, come as shapes F for the segment modules 4a, elbows F2 according to FIG. 4b, V-shaped pieces F3 4c, C-shaped fittings F4 according to FIG. 4d, fitting fittings F5 according to FIG. 4e, or link pieces F6 according to FIG. 4f or blunt Pie slices according to Figure 4g or rings R according to Figure 8 in question.
- segment modules of the same shape for example in Shape of a cuboid, see Figure 4, but one different content of expensive hard materials, such as Diamonds contain segments from them, according to FIG. 5, for example to produce as cutting segments for a saw blade whose edge A consists of a segment module M1, see Figure 5, which has a very high Content of hard material, such as diamonds, in contrast to the following segment modules, which alternate with low and somewhat higher hard material particles are enriched, with increasing Digit the content of hard material particles in the segment module decreases.
- the pattern groupings of a segment Different segment modules depend on the tool and the materials to be machined, the segments can be symmetrical or asymmetrical shape made up of different segment modules be, see e.g. B. segment pattern according to FIG. 6.
- segments are composed of segment modules, it being in particular it is possible to grade the individual segment modules, d. H. With to equip different quantities and / or qualities of hard materials and from this different qualities according to the requirements of modular segments.
- Sintered metals such as alloys based on cobalt, copper, tungsten, nickel, Iron, titanium, tin, aluminum and / or silicon used among others.
- segment modules according to the invention made of sintered metals and hard materials can be produced using hot isostatic pressing - HIP - whereby many segment modules can be produced simultaneously.
- the Segment modules can then use robots to achieve all of the desired modular segments are put together, taking out very quickly the relatively small number of different segment modules each desired qualities and shapes of segments can be.
- the modular segments Sm made up of segment modules M can as shown in Figure 7, on its later connection side with the tool carrier can already be equipped with a solder L. About that it is also possible, for example, in the columns between adjacent segment modules M a binder or plastic K, which gives the segment Sm a certain spring property is awarded.
- segment modules are rings, as in 8 shows the segment module MR in a ring shape.
- modular hollow beads be constructed as shown in Figure 9. Hollow beads are made for Wire saws needed.
- the individual segment modules can also be used here differ in their content of hard materials, for example put together, d. H. graded, creating an inexpensive modular Segment in the form of a hollow pearl can be produced.
- FIG. 11 schematically shows the top view from above Construction of a cutting segment from segment modules in the form of a The contra-angle handpiece M / F2 is shown, which is interlocked form a closed segment.
- segment modules designed as an elbow Arrange M / F2 so that parts of it, namely an angle arm alternating lateral, d. H. is arranged to the side above, the Central axis or movement axis of the segment Sm is designated by x.
- This formation of a segment SS is only possible with the help of the module structure and correspondingly designed segment modules according to the invention possible, the laterally protruding parts of the segment modules Have function of cooling fins, whereby the life of the Cutting segment increased and the quality of the cutting effect improved becomes.
- FIG. 12 shows, for example, the form-fitting arrangement of V-shaped fittings shown as segment modules M / F3 that for example in the direction of movement X in the front area Cutting segment a sharp edge can be formed.
- 13 is for example the construction of a cutting segment from segment modules in Shape of a fitting M / F4 shown.
- FIG. 14a shows segment modules which are in the form of a chain link M / F6 are formed to form a cutting segment Sm along its central axis X joined together, the thickened areas also laterally over project the formed segment Sm and thus in turn a cooling effect exhibit.
- FIG. 14b shows how this cooling effect is caused by a accordingly inclined arrangement of the segment modules M / F6 can be enlarged.
- Another way of training cutting segments in Modular structure by means of segment modules with cooling effect can in that the individual segment modules M in their arrangement within the segment from the central axis Y to the sides can be arranged alternately dumped, either for example in the arrangement shown in Figure 15 or in that of Figure also as cooling fins. Furthermore, this is also a Self-sharpening effect achieved for the Sm segment.
- segment modules are graded in themselves, d.
- the cuboid segment module M / V has a vertical grading with five areas, three areas V1 with a predetermined Concentration of hard material particles and the areas in between V0 with a lower concentration, possibly up to 0 hard materials are executed.
- Cutting segments allow adjustment in the radial direction typical cutting behavior of cutting tools. A saw blade, see FIG. 2, that with segments Sm from segment modules M / V according to FIG. 17 is sawn from the beginning to the end always with the same force fast.
- the alternating concentration of hard material particles in segment modules within a segment for example in the sequences M1, M2, M1, M2, M1, M2 ... or M1, M2, M3, M1, M2, M3, M1, M2, M3 ... enables a sawtooth effect.
- the segments from segment modules that the contain different concentrations of a hard material have in A first segment module considers the direction of movement of the segment M1 with maximum concentration of hard materials, the one Segment module M2 with minimal concentration of hard materials and then again a segment module M3 or M1 with higher than that minimum concentration up to maximum concentration Hard materials follows, and further segment modules alternate in analog Sequence.
- connection of the segments with the tool carrier can be done on the one hand done in a known manner by means of wettable solders, which also by Penetrating the gaps between the segment modules close them.
