Definitions
- the invention relates to a sawing wire for use in a wire saw machine, comprising a wire rope braided from a plurality of wire strands and cutting beads disposed thereon, the ends of the wire rope being spliced, in particular to an endless loop of rope. Furthermore, a method for the production of a sawing cable connection of cable ends of the sawing cable or of parts of the sawing cable, in particular to an endless sawing cable loop, should be specified.
- the wire saw machines which are of importance in connection with the present invention, are mainly used for natural stone processing.
- these are so-called “multiwire saws”, which allow a granite block to be cut simultaneously with up to 60 sawing wires.
- the Multiwire saws are characterized by a significantly higher output performance and an advantageous flexibility in the production of different plate thicknesses.
- the Multiwire saws can not use the saw wires used in Monowire saws.
- the saw wires used in the Multiwire saws must have a reduced diameter compared to the saw wires used in Monowire saws. This reduces the cutting losses at the same time.
- wire strands to be spliced are e.g. wrapped with plastic bands or the like.
- these solutions are not suitable for saw ropes due to typically an order of magnitude smaller diameter.
- the object of the present invention is therefore to provide a comparison with the prior art new cable connection for sawing cables, which avoids the disadvantages described above, thereby enabling in particular a time and cost savings.
- Shrink tubing is typically used in the electrical industry. These are plastic hoses, which contract strongly under the influence of heat (usually by supplying hot air). The aim is to electrically isolate the object introduced into the tube prior to heating against its environment. In the case of the sawing cable connection described herein, the objective of using the shrink tubing is primarily to improve the corrosion behavior of the wire strands and to increase the frictional engagement. It is also advantageous that the casing with shrink tubing
- shrink sleeves consist of a thermoplastic material with a shrinkage range between 2: 1 to 3: 1.
- the exact nature of the shrink tubing used in the individual case depends very much on the lichen formula - and thus the thickness - of the wire strands.
- the rope With a strand number of eg 6x7 + 1x7 - this means that the rope consists of 6 + 1 strands, each consisting of 7 wires - it makes sense to use shrink tubing whose outside diameter is 3 mm at a processing temperature of approx. 400 ° C shrinks to 2 mm.
- a preferred embodiment is characterized in that the splicing of the cable ends takes place using at least one cross knot.
- Cross knots are e.g. at Langsplei touch - a preferred splicing method in the context of the invention - used.
- Such long splices extend from the splice center in each case over a certain length in both directions of the rope.
- a sawing wire with a number of strands of 6x7 + 1x7 is a typical splice length, with a total cable length of typically 25 m to 65 m, for example, 2.4 m.
- other splicing techniques are also available. For example, it is conceivable to use a parallel node instead of the cross node.
- the splice is - preferably by means of a copper hammer and / or a pair of pliers - pressed.
- the aim here is to reduce the outer diameter of the sawing cable in order to arrange cutting beads in this area of the sawing wire can.
- the sheathing of the wire strands with shrink tubing is also very advantageous in view of this splice of the splice, since it helps to prevent mechanical damage that could occur in the course of Verpressvorgangs. It has also proved useful to coat the splice point with an injection-molded jacket, advantageously as well as the remaining sections of the sawing wire between the cutting beads.
- the injection molding jacket consists of a thermoplastic urethane-based elastomer.
- the injection molding jacket serves to protect the splice point - as well as the rest of the sawing wire - from external influences. This prevents corrosion and increases safety during use.
- the injection-molded jacket serves to stabilize and fix the cutting beads.
- the cutting beads are preferably completely injected.
- the cutting beads have a diameter between 6.5 mm and 8.5 mm, preferably a diameter of 7.3 mm. Cutting beads with this diameter can be ideally combined with a wire rope whose diameter is between 2.5 mm and 4.4 mm and preferably 3.5 mm.
- embodiments of the sawing cable according to the invention have been found to be advantageous in which between 30 and 40, preferably 36, cutting beads are arranged per meter on the wire rope.
- Protection is also desired for a method of making a sawing wire connection of cable ends of a sawing wire or parts of a sawing wire, in particular to an endless sawing wire loop, the sawing wire having a wire rope braided from a plurality of wire strands and cutting beads disposed thereon, characterized in that
- At least one of the wire strands is sheathed at least partially with at least one shrink tube at one end of the rope, and
- the cable ends are spliced together in a second step.
- This method can be extended by one or more of the following method steps:
- the splice is - at least partially pressed, preferably by means of a copper hammer and / or a pair of pliers, and / or
- At least one cutting bead is pushed over the splice, and / or the splice is encased at least in regions with an injection-molded jacket.
- FIG. 1 is a schematic representation of two ends of a sawing cable according to the invention
- Fig. 2 is a schematic representation of a sawing cable according to the invention with a splice
- FIG. 3 shows the preferred method sequence for the production of a sawing wire connection according to the invention in the form of a block diagram.
- FIG. 1 schematically shows two ends 3 of a sawing cable according to the invention, the sawing wire having a wire rope braided from a plurality of wire strands 1 and cutting beads 2 arranged thereon.
- the cutting beads 2 contain a high performance cutting material, such as diamond.
- the intertwining of the wire strands 1 is indicated only schematically in this illustration.
- an injection molding jacket 5 is shown, with the advantageously the entire sawing cable (at the locations that are not occupied by Scheidperlen 2) is sheathed.
- the two cable ends 3 are connected to each other according to the invention, which is indicated in the figure with the two arrows and described in detail with reference to FIG. 3.
- FIG. 2 shows a sawing cable according to the invention, in which the ends of the wire rope have already been connected to one another. So it is a section of an endless rope loop to see.
- the area over which the splice extends is designated v. It should be noted that - as in the case of FIG. 1 - this is not a true-to-scale illustration. Typical values are in reality:
- Diameter of the wire rope 3.5 mm
- Diameter of the cutting beads 2 7.3 mm
- Diameter of the wire rope with injection-molded jacket > 3.5 mm and ⁇ 7.3 mm This means that in the region of the splice in this embodiment approximately 100 cutting beads are arranged. For the sake of clarity, the region of the splice is shown interrupted by dashed lines.
- the wire strands 1, with which the splicing of the cable ends 3 is to take place, are encased in the process step indicated by A in FIG. 3 over the entire area v of the splice with a heat-shrinkable tube 4.
- a heat-shrinkable tube 4 For this purpose, one first separates these wire strands 1 spatially from the other wire strands 1, which are not required for the splice. Then one evert one or more shrink tubing 4 as required over the leached wire strands 1 and lets these heat shrink tubing 4 contract as a result of heat.
- the two cable ends 3 are spliced by a long splice using a cross knot.
- the splice is pressed by means of a copper hammer and a pair of pliers in order to reduce the outside diameter in the region v of the splice.
- the cutting beads 2 which have been parked on the right and left of the splice, are pushed over the splice and arranged at the same distance as in the remaining sawing wire.
