    The invention relates to a sawing wire for use in a wire sawing machine, comprising a wire rope and cutting beads arranged thereon, the ends of the wire rope being connected together by a sleeve-like press fastener.
    The saw ropes, which are of importance in connection with the present invention, are used in particular in wire sawing machines for natural stone processing. The saw ropes consist essentially of a wire rope, which is composed of a plurality of interwoven Einzeidrähten and on which at certain intervals cutting beads are arranged. The cutting coating of these cutting beads typically includes a high performance cutting material, such as a high performance cutting material. Diamond.
    Preferably, the sawing cables are used in the wire sawing machines in the form of endlessly circulating cable loops, i. that the ends of the wire rope must be connected together. For this purpose, a number of different closure techniques are available, of which the use of sleeve-like press fasteners has proven to be particularly cost-effective.
    Such press fasteners are known in the art and are e.g. from the European patent application EP 0 450 506 A2. It is usually a cylinder tube made of steel or copper, which is pressed with the two ends of the rope. These press fasteners are usually used on saw ropes with a bead diameter between 8 mm and 11 mm. The life of the shutter is about 100 hours. After that he will be exchanged. The cycle of exchange is a fraction of the total life of the saw ropes. The reason for the premature replacement is the occurrence of wire breaks immediately in front of or behind the press fastener. With an increasing number of these individual wire breaks, it then comes to the breakage of the entire wire rope at one of the two places. This violent breakage can be explained, in particular, by the occurrence of notch stresses in the transition between fastener and wire rope. 2
    At present, efforts are being made to develop sawing wires with a smaller bead diameter (e.g., 7.3 mm). These saw ropes are especially intended for use in so-called "multiwire saws", multiwire saws make it possible, for example, to cut a granite block with up to 60 sawing cables simultaneously. They are characterized by a high output and advantageous flexibility in the production of different plate thicknesses. A reduction in the diameter of the cutting beads is therefore desirable because it could reduce the required cutting power and at the same time the cutting losses.
    However, a reduction in the diameter of the cutting beads also requires a reduction in the diameter of the wire rope on which the cutting beads are arranged. In an attempt to join the ends of the reduced-diameter wire rope with the sleeve-type press fasteners known in the prior art, it was found that the above-described problems were more pronounced. Therefore, the life of the closures was only about 80 hours.
    The object of the present invention is to provide a comparison with the prior art improved sleeve-like press fastener for sawing cables, with which the disadvantages described above are avoided. In particular, an increased life of the closure is to be achieved, which subsequently leads to a significant time and cost savings.
    This object is achieved in that the sleeve-like press closure has an area of reduced rigidity at least one end.
    The term stiffness is generally understood to mean the resistance of a body to deformation by a force or torque. The rigidity of a body depends on its material and its geometry. Depending on the type of load, a distinction is made between different stiffnesses, such as e.g. Bending, expansion or torsional rigidity, wherein in view of the present invention 3 in particular the bending stiffness is important. If the sleeve-like press closure has a region of reduced rigidity at at least one end, this leads to the transition of the closure and the wire rope becoming more homogeneous or more continuous from the point of view of the stresses occurring in the process.
    In an advantageous embodiment, the sleeve-like press closure is made of steel, preferably of nickel-alloyed case-hardening steel. Case hardening steels include unalloyed and low alloy steels up to a maximum carbon content of 0.2%. Components made of case-hardening steels have a high degree of toughness in their interior and a very high hardness and thus high resistance to wear on the surface. An example of a nickel-alloyed case hardening steel is the material 15CrNi13. It is characterized by a tensile strength of 1000 to 1100 N / mm2. Thus, a minimum tensile force of 5000 N can be guaranteed. Pressures of 400 kN are necessary for pressing a press fastener made of this material.
    The range of reduced stiffness may be e.g. be achieved in that the sleeve-like press closure at the respective end has a material taper. Alternatively or as an additional measure, the rigidity at the ends of the sleeve-like press closure can be reduced by slit-shaped interruptions, for example six slit-shaped interruptions.
    Furthermore, it has proved to be advantageous if the sleeve-like press closure has at least one end at least one annular recess, wherein the at least one annular recess is preferably arranged between the inner surface of the sleeve-like press closure and the wire rope. This means that the inner surface of the sleeve-like press closure rests against the wire rope only in the region of the center of the sleeve-like press closure. It is conceivable that the at least one annular recess remains empty or in that at least one sleeve-like component, e.g. made of plastic (preferably made of Teflon) is arranged and / or that the at least one annular recess at least partially filled with a plastic, preferably with a thermoplastic urethane-based elastomer. All these measures 4 or combinations of these measures serve to create a more homogeneous or more stable transition of closure and wire rope.
    The plastic mentioned in the last paragraph, with which the at least one annular recess can be filled at least partially, is advantageously also used to encase the sleeve-like press closure and / or the wire rope {at the locations between the cutting beads) at least in regions with an injection-molded jacket. In general, such an injection-molded jacket serves to protect the wire from external influences. This prevents corrosion and increases safety during use. In addition, the injection-molded jacket serves to stabilize and fix the cutting beads. For this purpose, the cutting beads are preferably completely injected.
    When manufacturing the sawing cable according to the invention, it is advantageously to be ensured that the distance of the two cutting beads adjacent to the sleeve-like press fastener is matched as well as possible to the spacing of the remaining cutting beads, since otherwise it is e.g. During a periodic orbital movement of an endless sawing cable in a multiwire saw to unwanted vibrations. However, this succeeds only partially due to the necessary minimum width of the sleeve-like press fastener.
    Therefore, the two adjacent to the sleeve-like press closure cutting beads are generally subjected to increased stress. For this reason, it has proved in some cases to be advantageous if at least one of the two adjacent to the sleeve-like press closure cutting beads has a wear-resistant compared to the other cutting beads cutting pad. This can e.g. be achieved by a hardened bond and / or a higher diamond concentration.
    As a further compensation measure against the background of an increased load, it can be provided that at least one of the two cutting beads adjacent to the sleeve-like press closure has an extension part welded to the carrier body of the cutting pad, the welded extension part being arranged on the side of the cutting beads sleeve-like press closure facing away. This welded extension part serves to reinforce the carrier body of the cutting pad. However, care must be taken that in the transition region of the welded extension part to the wire rope not similar problems as in the sleeve-like press-lock occur. This can be achieved in that the free end of the welded extension part has at least one slot-shaped interruption, preferably six slot-shaped interruptions.
    As stated above, it will be endeavored to adapt the distance of the two adjacent to the sleeve-like press closure cutting beads as well as possible to the distance of the other cutting beads. This means that you also want to achieve the smallest possible distance between these two beads to the press fastener. However, the bending elasticity of the sections between these two beads and the press fastener must not be restricted too much. An advantageous compromise between a small distance and a relatively high elasticity of the sections can be achieved in that at least one of the two adjacent to the hüisenartigen press closure cutting beads one of the two parts of the carrier body, which protrude at the other cutting beads on the cutting surface, missing wherein the part of the carrier body is missing on the sleeve-like press closure facing side of the cutting bead. Again, it is important to ensure that there is no too abrupt transition of wire rope and cutting bead. For this reason, it can be provided that the carrier body of at least one of the two adjacent to the sleeve-like press closure cutting beads has at least one annular recess, wherein the at least one annular recess is arranged at the end of the carrier body, which faces the sleeve-like press fastener. Similar to the sleeve-like press closure, the at least one annular recess is preferably arranged between the inner surface of the carrier body and the wire rope. It may also either remain empty or have at least one sleeve-like component made of plastic (preferably made of Teflon) arranged in it and / or at least in some areas with a 6
    Plastic, preferably with a thermoplastic elastomer based on urethane, be filled.
    Further details and advantages of the present invention will be explained in more detail below with reference to the description of the figures with reference to the exemplary embodiments illustrated in the drawings. Showing:
    1 is a schematic cross-sectional view of a detail of a sawing cable according to the invention,
    2 is a schematic side view of one of the two adjacent to the sleeve-like press closure cutting beads,
    3 shows a schematic side view of an embodiment of the sleeve-like press closure, and FIG. 4 shows a schematic cross-sectional view of another embodiment of the sleeve-like press closure.
    In FIG. 1, a section of the sawing cable 1 relevant for explaining the invention is shown schematically in cross section. This cutout may be part of a sawing cable 1 connected to an endless rope loop, for example. Because the length of such a cable loop is typically several meters (for example 50 m) and the section shown here is actually a length of a few centimeters, the curvature of the sawing cable 1 can not be seen in this illustration. The section shows (viewed from the center to the edge of the drawing): a sleeve-like press fastener 5, through which the ends 4 of the wire rope 2 are connected, two adjacent to the sleeve-like press closure 5 cutting beads 3 'and 3 ", located in their Construction of the remaining cutting beads 3, two of which can be seen at the edges of the drawing, different. All the cutting beads 3, 3 'and 3 "are arranged on the wire rope 2. The sleeve-like press fastener 5, which is made of nickel-alloyed insert steel in the embodiment shown here, will be described in more detail below with reference to FIG. It should be noted at this point that the sleeve-like press closure 5 has at each end 6 an area of reduced rigidity, which in each case is increased by an outwardly increasing shoulder 7
    Material rejuvenation 7 is caused. At the same time, the outer diameter D5 of the sleeve-like press closure 5, which has substantially the shape of a cylinder tube, is constant over the entire width. This means that the sleeve-like press closure 5 rests in the region A4 of its center with the inner surface directly on the wire rope 2, however, at the ends 6 with the material taper 7 has a distance D2 to the wire 2. In other words, the sleeve-like press closure 5 at the two ends 6 in each case an annular recess 9, which is arranged between its inner surface and the wire rope 2. In the two annular recesses 9, a sleeve-like component 10 made of Teflon is arranged in each case, wherein this sleeve-like component 10 does not ausfüilt the entire recess 9. The remaining part of the recess 9 is rather filled with a thermoplastic elastomer 11 based on urethane. This plastic 11 also surrounds the entire sleeve-like press closure 5 and extends to the two adjacent cutting beads 3 'and 3 "zoom. In particular, this injection-molded casing 11 prevents corrosion damage to the press-on closure 5. The cutting beads 3, 3 'and 3 "essentially consist of a carrier body 13, on each of which an annular cutting coating 12 is arranged. The two adjacent to the sleeve-like press closure 5 cutting beads 3 'and 3 "differ in their construction - as stated above - from the remaining cutting beads 3, which are arranged on the wire rope 2. Their construction will be explained in detail with reference to FIG. 2. At this point, attention is drawn to the annular recess 18 at the end of the carrier body 13, which faces the sleeve-like press closure 5. This recess 18 is also filled with the urethane-based thermoplastic elastomer 11 from which the injection molding jacket is made. The sections of the wire rope 2 between the cutting beads 3, 3 'and 3 "are also sheathed with this plastic 11. It should be noted that here (as with the other figures) are not true to scale illustrations. In reality: the outer diameter D1 of the wire rope 2 is typically between 2.5 mm and 4.4 mm and is preferably 3.5 mm, 8 • the distance A1 of the sleeve-like press closure 5 to the two adjacent cutting beads 3 'and 3 " approximately 5 mm, the two transition zones A2 and A3 have a length of 1 to 2 mm at the ends 6 of the press closure 5, which are characterized by the splashed area A2 and the area A3 in which the teflon sleeve 10 is arranged • the length A4 of the area in the center of the sleeve-like press closure 5 is typically between 6 and 7 mm, • the distance D2 of the inner surface of the sleeve-like press closure 5 to the wire rope 2 at the two ends 6 has a value of about 0.5 and the distance A5 of two cutting beads 3 is typically about 2.5 cm, wherein the distance between the two adjacent to the sleeve-like press closure 5 cutting beads 3 'and 3 t; in comparison to this is a bit bigger.
    Overall, 30 to 40, preferably 36 Schneidperien 3, 3 'and 3 "are arranged per meter on the wire rope 2. In the case of a sawing wire 1 which has a length of 50 m and has 36 cutting heads 3, 3 'and 3 "per meter, this is then a total of 1800 cutting dies 3, 3' and 3". Due to the fact that the distance between the two adjacent to the sleeve-like press closure 5 Schneidperien 3 'and 3 "is slightly larger than the distance of the other Schneidperien 3, these two adjacent Schneidperien 3' and 3" are exposed to an increased load. This concerns above all the cutting bead 3 ', which is arranged behind the closure 5 in the running direction L of the sawing cable 1. Among other things, this increased load is taken into account by the fact that the cutting surface 12 of this cutting bead 3 'is designed to be more wear-resistant in comparison with the other cutting edges 3 and 3 ".
    The exact construction of the two adjacent to the sleeve-like press closure 5 Schneidperien 3 'and 3 "will be explained in more detail below with reference to FIG. 2: Shown here is the seen in the direction L behind the sleeve-like press fastener 5 arranged cutting bead 3'. The seen in the direction L before the sleeve-like press closure 5 9 arranged
    Cutting bead 3 "is mirror-symmetrical (except for the different cutting surfaces). It is a side view of the cutting bead 3 ', wherein the cutting pad 12 and the carrier body 13 are shown interrupted to release the view of the observer on the underlying areas. Attention is drawn to the following features: on the side of the cutting bead 3 'facing the sleeve-like press closure 5, the part 17 of the carrier body 13 which protrudes beyond the cutting surface 12 in the remaining cutting beads 3 is missing; • on the opposite side of this part 17 of the support body 13 is present; • on the side of the cutting bead 3 ', which faces away from the sleeve-like Pressverschuuss 5, there is a welded to the carrier body 13 of the cutting pad 12 extension member 14, wherein the weld is provided with the reference numeral 20; • the free end 15 of the welded extension part 14 has six slot-shaped interruptions 16 (of which only three are visible in the drawing).
    The outer diameter D4 of the cutting beads is (in reality) between 6.5 mm and 8.5 mm, and is preferably 7.3 mm. The outer diameter D3 of the carrier body 13 and the welded extension part 14 then has a value of about 5.2 mm.
    FIG. 3 shows an enlarged view of the sleeve-like press closure 5, which is likewise a side view. In this case, the wall of the press fastener 5 is shown interrupted to release the view of the viewer on the arranged within the shutter 5 areas: To be seen (viewed from the center to the edge of the drawing): the two wire ends 4, which in direct Contact with the inner surface of the press fastener 5 are two sleeve-like components 10 made of Teflon, which are disposed within the annular recess 9 between the inner surface of the press fastener 5 and the wire rope 2 and a plurality of slit-shaped interruptions 10 8, the press fastener 5 at its two ends. 6 having. In this illustration, the material tapering 7 of the press fastener 5 increasing toward the outside can also be seen very well. The outer diameter DS of the press fastener is (in reality) about 5.5 mm.
    4 shows a further exemplary embodiment of the sleeve-like press closure 5 in a schematic cross-sectional representation. In contrast to the embodiment disclosed in FIGS. 1 and 3, the press fastener 5 lies with its entire inner surface directly against the wire rope 2 and has no annular recesses at the ends. In addition, the material taper 7 is not stepped. Instead, the outer diameter D5 of the press closure 5 approaches the diameter D1 of the wire rope 2 substantially asymptotically.
