Definitions

  • the diamond plates which here are optionally C-shaped and / or L-shaped, also lie flat on the strands of the belt body movement, but in each case there is a sheet between the strands and the underside of the diamond plates inserted, which is correspondingly C or L-shaped.
  • the diamond plates are supported on the interposed sheets.
  • the anchoring of the diamond plates in the belt body is rather worse than in the exemplary embodiment described above, because the interposition of C- or L-shaped plates requires an additional fastening of the plates on both sides to the diamond plates and to or in the belt body, and in this respect one additional attachment must be carried out, but can also come loose in use.
  • tool carriers are also embedded flush with the surface and sides of the belt body. They also lie on the strands of wire ropes, which are arranged in a row and are embedded in the belt body, but in this embodiment there are drive blocks interposed, that of bores and of those in the Boring strands are penetrated and on the top of the tool holder are soldered.
  • the drive blocks have a smaller width than the belt body, so that the tool carriers which are flush with the belt body project beyond the drive blocks on both sides.
  • Each tool carrier has one or two slots open at the front for receiving narrow diamond cutting elements, which are arranged on successive tool carriers so that a profile cut can be carried out with the cutting belt, in which a certain part of the cutting profile is assigned to each diamond cutting element.
  • each diamond plate has a width which essentially corresponds to the cutting width, and the diamond plates — as seen in the running direction of the cutting belt — lie in alignment in a row.
  • a different attachment of the tool carrier is used in another known cutter arm (EP-B1-14776).
  • a continuously flat belt is used, in which neither tool carriers nor guide elements etc. are molded, but the plate-shaped tool carriers with diamond cutting strips are, like each one, arranged below the tool carriers on the opposite underside of the cutting belt Sliding shoes attached to the belt by means of bolts.
  • An extremely high water pressure in connection with a large amount of water is required to achieve a water sliding layer for separating the underside of the sliding shoes on the bottom of the guide channel.
  • the tool carriers and also underlying support and guide elements are fastened by means of screw bolts to a plastic cutting belt, even if the cutting belt is guided in the guide channel in a manner different from the aforementioned cutting arm, as will be explained later.
  • this object is achieved in that the diamond plates are fastened on solid tool carriers which have through openings such as bores or elongated holes arranged in a row next to one another or only a single elongated hole and are formed together with the diamond plates in the belt body, and in that the strands Immediately assert tool carriers by going through the openings such as holes or Extend elongated holes.
  • This new solution allows simple and safe embedding and anchoring of the diamond plates in the belt body of the cutting belt, in that the diamond plates form a compact, robust unit with the tool carriers, which are inextricably anchored directly to the reinforcement of the belt body, by the strands, which preferably consist of wire cables the tool carrier through the reinforcement.
  • the result is a fastening of the tool carrier in the belt body, which is secure against tilting from various types and from all possible directions, and thus also the diamond plates, which are firmly connected to the tool carrier to form a single component.
  • the tool carrier the upper part of which consists of the diamond plate, thus assumes the function of absolutely secure and permanent attachment of the tool or the diamond plate to the cutting belt in an arrangement embedded in the belt body and positively connected to its reinforcement. It supports the other functions of guiding and carrying the cutting belt directly on the guide and in the cutting area.
  • the tool holder which is practically coated with the diamond plate, forms an extremely robust and, in comparison to the prior art, relatively flat component, which therefore allows the use of a plastic belt body of relatively small thickness and thus a particularly tilt-proof construction.
  • the form-fitting attachment of the tool carrier in the belt body is relatively easy to produce by first pulling the tool carrier onto the strands and the reinforcement with the diamond plates load-bearing tool carriers are then encapsulated in a mold for producing the belt body with plastic, the cutting surfaces necessary for the cut remaining free on the top and on the side surfaces of the diamond plates, as is preferably the bottom of the tool carriers.
  • the tool carriers have through openings for receiving the strands so that the diamond plates can be supported directly on or on the strands via the tool carriers.
  • the openings can consist of a row of holes arranged side by side, so that the strands are individually guided through corresponding openings or holes in the tool carrier, preferably with a close fit, in order to anchor and support the diamond plates in the belt body as securely as possible through close contact between them to reach the tool carriers and the strands.
  • elongated holes or only a single slot-shaped elongated hole could also be provided.
  • the strands that pass through the tool carriers consist of the loops or windings of the single rope strand running multiple times through the cutting belt with a single connection point.
  • the splicing work during the production of the strands is considerably reduced because only the two ends of the single rope strand used are to be connected to one another. At the same time, there is no corresponding number of connection points as weak points in the reinforcement.
  • the tool carriers in the longitudinal direction of the cutting belt are each longer than the diamond plates.
  • the underside of the tool carrier should run as flush as possible with the underside of the belt body.
  • the tool carriers each end in the transverse direction of the cutting belt at a distance from the side surfaces of the belt body
  • the diamond plates are designed in an L-shaped cross section with a short and a long leg, and the short legs of the diamond plates perpendicular to the belt running direction alternating from one side to the other, bear against the inside of the tool carrier and finish flush on the outside with the respective side surface of the belt body.
  • a short leg of the associated diamond plate and a plastic extension of the belt body lie opposite each other on the sides of the tool carrier, alternately on the right and left.
  • cross-section of the upper side of the belt body and the diamond plates in cross-section run at an obtuse angle, flush with one another and that the tool carriers on their upper side are designed in a correspondingly gable-shaped manner.
  • the gable shape results in cutting force components that guide the cutting arm and prevent the cutting arm from running.
  • the diamond plates and the tool carrier are securely anchored in the belt body of the cutting belt because, compared to the essential cutting forces, also against lateral forces, there is still a positive fit between the tool carriers and diamond plates on the one hand and the embedded strands on the other.
  • a tool holder with a diamond plate is embedded in the belt body in an oblique position with respect to the belt running direction for a free cut.
  • the positive connection is retained. Only the bores have to be widened slightly so that the strands can penetrate the bores in a straight direction even when the tool holder is at an angle.
  • the new provision provides that the belt body sections between the diamond plates over the top of the cutting belt and transversely to the belt running direction have continuous grooves or troughs or the like in particular.
  • the grooves should suitably have the shape of fillets.
  • the upper side of the belt body sections between the diamond plates have zigzag-shaped, mutually engaging and juxtaposed grooves and / or lateral recesses pointing in the direction of the belt.
  • the web which is important for guiding the cutting belt, should also be fastened to the underside of the belt body or the tool carrier as a separately produced part on the underside of the belt body and the tool carrier.
  • This attachment allows the use of a simpler shape when embedding the reinforcement and the tool carrier and diamond plates in the manufacture of the belt body by plastic injection.
  • the guide channel expediently consists of two side walls, between which a recessed bar is arranged, and the side walls are intended to form a container for water for cooling the tools and as pressurized water for building up a sliding film with the bar, the bar being spaced apart from holes for feeding of cooling water to the guide channel.
  • the web of the cutting belt which is made of plastic, is to take over the guidance of the cutting belt in the guide channel, the lower surfaces of the belt body adjoining the web on both sides and the tool carrier contributing to the guidance, namely in particular should counteract occurring tilting forces, and for this purpose it is provided according to the innovation that the web of the cutting belt which engages in the guide channel slides during operation on the surface of the bar covered with a cooling water film and the free lower surfaces of the belt body and the tool carrier slide on the outer narrow sides of the side walls of the guide channel and are led.
  • a very important development of the innovation is characterized in that the web of the cutting belt rests on an endless flexible inner belt which rotates on rolling bodies which roll on the surface of the bar in the guide channel.
  • Use is made here of the guidance and support of the cutting belt known from EP-A1-358112.
  • the flexible inner belt should have two guide strips arranged at a distance, which receive the web of the cutting belt between them.
  • the cutting belt is mounted on guide rollers which are rotatably mounted in the guide channel and are double-T-shaped in cross section, and the web of the belt body is accommodated in the guide region of the guide rollers is.
  • the guide rollers serve here directly for storing and receiving the cutting belt, without the flexible inner belt.
  • they are fixed in a rotatable manner in the guide channel and carry the web of the belt body of the cutting belt directly in their upper region, where the web has a receiving surface and lateral guide surfaces on the guide rollers.
  • the attachment the tool carrier and diamond plates in the cutting belt can be designed in the same way as in the case of the aforementioned alternative development of the innovation.
  • each diamond plate is fastened on a web which is detachably fastened in a correspondingly shaped groove of the associated tool carrier which runs transversely to the longitudinal direction of the cutting belt.
  • This releasable attachment of the diamond plates, also called diamond cutting segments, to the cutting belt leads to a number of advantages, which are explained below.
  • the diamond plates can be selected depending on the type of material to be cut with regard to the grain size and bond of the diamond particles. It is possible to select the diamond plates to be attached to the cutting belt only after the cutting belt has been manufactured, so that the manufacturer of the cutting belt can produce a number of cutting belts independently of customer orders specified with regard to the selection of diamond plates and can fit these with the corresponding diamond plates as soon as a customer receives a cutting belt ordered according to selected diamond plates.
  • the delivery times for cutting belts are reduced for the customers.
  • the users can replace the diamond plates on the spot, for example in the quarry itself, and no longer only in the workshop if diamond plates are worn out or there is a need for another type of diamond plate. This advantage significantly reduces maintenance costs and any downtime when diamond plates have to be replaced due to wear or other reasons.
  • a detachable connection between a web below the diamond plate and a groove in the associated tool carrier allows the entire top of the diamond plate and the short side leg, which also cuts, to be cut without interruption through screw holes or screw heads or the like.
  • the web and the groove form a dovetail guide with a wedge shape for the purpose of releasable fastening of the diamond plate to the tool carrier. Because in this way you can easily, namely in particular with hammer blows, to produce and unintentionally unreleasable connection between the diamond plate and the tool holder, and on the other hand, the web with the diamond plate can also be easily removed from the tool holder by appropriate hammer blows.
  • the main direction of loading when cutting is transverse to the direction of movement when attaching or detaching, so that the tight fit of the web in the groove is not touched by the cutting forces.
  • the ridge of the angular diamond plate is pushed into the groove practically from the cutting side, namely from the side on which the short leg of the diamond plate is located, which is provided for the side cut.
  • the cutting forces acting on the short leg reinforce the seat of the web in the groove; in no case do they act in a direction of movement of the web which could result in the web being released from the groove.
  • any cutting components only press the dovetail bar even more forcefully into the dovetail groove. Due to this design, the diamond plate is fastened over its entire width, in contrast to fastening using screws or the like. If the belt body of the cutting belt is worn out, the diamond plates can be recovered.
  • the groove-web connection with a wedge-shaped dovetail cross-section can be produced easily and quickly and reliably, but is still easy to release.
  • the long leg of the angular diamond plate is fastened to the tapered upper side of the web and the short leg to the large or outer end face of the web.
  • the sides of the diamond plate facing the web thus form components or guide surfaces and stops of the dovetail guide.
  • the long leg of the diamond plate projects beyond the web at the free end and the tapered front side of the web, which is set back in the belt body, is delimited by the extension of the belt body, so that the free front side of the diamond plate is flush with the side surface of the belt body.
  • the dovetail guide made of groove and web should be arranged above the strands passing through the tool carrier in bores. Especially with The bores distributed across the width of the tool carrier and the strands passing through these bores as well as the plastic molding compound ensure that each tool carrier is securely anchored in the cutting belt.
  • the dovetail guide for fastening the diamond plates then runs directly and closely above the bores and strands, so that the belt and the tools attached to it are compact.
  • the short leg of the diamond plate should be flush with the tool carrier at the bottom so that the short leg can be inserted over the entire height of the belt in the area of the tool carrier.
  • top of the leg of the diamond plate should be flush with the top of the belt body, so that the entire width of the cutting belt of the diamond plate can also be cut here.
  • the angular diamond plates are driven alternately from the right and from the left onto the tool carrier. This alternating arrangement results in an even cut on both sides.
  • a stop is provided to limit the drive-in path of the web in the groove, so that the diamond plates are centered as precisely as possible on the cutting belt.
  • the legs of the diamond plate should be about the same width as the largest width of the groove, and they should protrude on both sides of the web in the width direction.
  • the tool carriers are expediently much wider than the diamond plates, for example about twice as wide.
  • a cutting belt generally designated 1, of which only a section is shown in FIGS. 1-3, essentially consists of a belt body 2 made of plastic and of a series of strands 3 of wire ropes lying at a distance from one another as reinforcement of the cutting belt 1, which have been embedded in the belt body 2 during injection molding.
  • the belt body 2 has transverse grooves 4 on its upper side and on its two side surfaces, which, as shown, are designed in the manner of fillets and are used for removing cooling water and scrapings.
  • a web 5 made of plastic for guiding and supporting the belt body 2 and the components integrated in the belt body is attached in a central position, for example glued on.
  • solid and compact tool holders 6, preferably made of steel, are embedded in the belt body 2 at intervals.
  • the tool carriers 6 are securely anchored in the belt body 2 in that they have a row of bores 7, in the present exemplary embodiment four bores 7, at a distance from one another, through which the strands 3 of the reinforcement of the cutting belt 1 extend.

  • the width of the tool carrier 6 is, as the drawing shows, less than the belt width, on both sides, so that the alternating arrangement of the L-shaped diamond plates 8 results in a short leg 11 of the diamond plate 8 and an extension 12 of the belt body 2 opposite each other, however in an alternating arrangement from one side to the other from one tool carrier 6.
  • the tool carrier 6 - seen in the longitudinal direction of the belt - is longer on both sides than the associated diamond plate 8.
  • the tool in the form of the diamond plate 8 has a relatively wide support directly on the reinforcement in the form of the strands 3 without the flexibility of the cutting belt 1 perpendicular to the longitudinal direction is restricted.
  • the tool carriers 6 are first drawn onto the strands 3 of the reinforcement, as illustrated in FIG. Since the cutting belt 1 is endless, the strands 3 are firmly connected to one another, for example by a metal sleeve 9. Only then is the reinforcement with the tool carrier 6 introduced into the mold, where the belt body 2 is formed by plastic injection, the reinforcement from the strands 3 with the tool carriers 6 being embedded in the belt body 2 as described above and shown in the drawing .
