Definitions

  • the invention relates to a saw band for a band saw, a band saw with a saw band according to the invention and individual links of a saw band according to the invention.
  • Band saws and the endless saw bands running around them are used to cut a wide variety of materials.
  • band saws are used to separate semi-finished products but also for precise cuts.
  • the endless rotating saw band offers numerous advantages.
  • the cutting direction of a band saw is always oriented perpendicular to the bending direction of the saw band, thus enabling a very flexible cut. This is not the case, for example, with a chainsaw, because there the chain must be circulated in the cutting plane, which requires a certain width of the sword and means a significant impairment with regard to the cut, in particular with regard to the cutting radii.
  • the saw band does not have to have its own compressive strength, since it is always pulled through the cut under a certain tension.
  • a circular or jigsaw must therefore have a comparatively thicker saw blade because the cutting pressure must also be withstood as a pure pressure load. Furthermore, modern band saws own freedom in cutting is a great advantage. The cut can be made along almost any straight line in the room. Depending on the material thickness to be cut, the material properties, the length of the endless rotation of the saw band and the band material, extremely high cutting speeds can also be achieved with a band saw. In contrast to a circular saw, the time between periodically successive interventions of a saw blade piece is usually longer in a band saw. Cooling and cleaning the saw band is therefore technically much easier and more effective to solve. The cooling can be brought about, for example, in a simple manner by means of a liquid bath. Wiping cleaning elements can be attached almost anywhere in the endless rotation of the saw band.
  • a big disadvantage of previous band saws is the susceptibility of the saw band to defects.
  • the necessary flexibility of the saw band requires a comparatively thin material thickness, which is why saw bands have a comparatively short service life compared to their specific cutting use.
  • a fault in a saw band for example a broken tooth, makes it necessary to replace the entire band.
  • a saw blade with a high quality cutting material e.g. B. a diamond assembly, usually not.
  • stone cutting machines for example, are usually operated with high-speed diamond cutting discs as a wet cutting system. In the absence of a diamond-tipped saw band, the use of a dry-operated band saw with controlled dust guidance is therefore difficult.
  • the object is achieved by a saw band of the type mentioned at the beginning, in which the saw band consists of individual members which are connected to one another and arranged in the running direction. Furthermore, the individual links of a saw band according to the invention and a band saw with a saw band according to the invention are the subject of the invention.
  • the decisive advantage of the saw band according to the invention is that the saw band can be broken down into individual links. In this way, defective links can be easily replaced.
  • the average service life of a saw band is therefore no longer dependent on a mostly random individual error in the entire rotation of the saw band, but is determined by the average service life of the individual links.
  • the failure probability of a conventional saw band is determined from the sum of the failure probabilities of the individual teeth.
  • the division of the saw band according to the invention into individual interconnected links arranged one behind the other in the direction of travel enables the probability of failure of the saw band to be reduced to the failure probability of a single link, which again results from the sum of the failure probabilities of the individual teeth.
  • a saw band according to the invention has only a fraction of the probability of failure of a conventional saw band and therefore has a significantly longer service life. Because of the long service life, it is economical with the saw band according to the invention to provide the individual links with diamond particles or diamond segments. If one of the high-quality elements of the saw band fails, it can advantageously be easily replaced and the entire saw band does not have to be discarded.
  • a useful development of the saw band according to the invention provides that the individual links are articulated to one another. By means of an articulated connection of the individual links, it is possible to make the single link more resistant, possibly completely stiff.
  • the service life of the saw band is also advantageously increased by the robust design of the articulated individual links.
  • the band saw's previously flexible design of the saw band and the resulting resulting flexible, thin construction of the saw band is no longer necessary.
  • an articulated connection according to the invention between individual rigid links is a great technical gain.
  • the individual diamond segments are usually manufactured as a sintered component consisting of diamond dust and a binder. Naturally, these segments are rigid and, due to their size, cannot be connected with a conventional flexible saw band.
  • With the saw band according to the invention it is possible for the first time to operate a band saw with a saw band equipped with diamond segments because of the use of rigid articulated links.
  • Another embodiment of the saw band according to the invention provides that the individual links are flexible in themselves and thus an articulated connection of the individual links to one another is not a mandatory requirement. This can be particularly advantageous for cutting tasks that are less stressful, such as in the meat industry.
  • a particularly stable design of the saw band is obtained when the individual links are positively connected to one another.
  • Such a connection can advantageously be detachable. It is particularly useful to use an exclusively form-fitting connection, which can be assembled and disassembled by simply hanging and unhooking the individual links.
  • An advantageous development of the invention provides that the individual links each have at least one recess and at least one retaining element, the retaining element of one link engaging in each case in a recess of an adjacent link and in this way a tensile connection between the adjacent links is formed.
  • Each link in the longitudinal direction of the saw band expediently has a holding element on one side and a recess on the opposite side. In this way, the holding elements of the identical links can each engage in the recess of the adjacent link.
  • a band saw with a saw band according to the invention that runs vertically is particularly useful for cutting stones.
  • the stones which are usually in the form of plates, can expediently be cut up on the base plate, which is generally oriented perpendicular to the direction of travel of the saw band. Since the resulting dust is not whirled up as in the use of a circular saw or cutting disc in the dry-cutting process, the resulting dust can be sucked off almost without residue.
  • the generally endless saw band is guided over at least part of the circulation by means of a guide rail. This also calms the running behavior of the entire band saw and reduces wear on the components involved.
  • the saw band has no guide in the cutting area.
  • FIG. 1 is a plan view of a link of a saw band according to the invention
  • Fig. 2 is a plan view of the connection of two
  • Fig. 3 shows a section through an inventive
  • Fig. 4 is a front view of a link of a saw band according to the invention.
  • the link 1 of a saw band according to the invention shown in FIG. 1 is provided with the reference number 1 in its entirety.
  • a holding element 2 In the running direction of the saw band on one side of the link 1 there is a holding element 2 and on the opposite side in the running direction there is a recess 3 which is delimited by a holding piece 3a in the running direction.
  • the holding element 2 and the holding piece 3a each extend transversely to the running direction of the saw band and parallel in the cutting direction.
  • the recess 3 is designed as a circular segment, the secant of the circular segment having a length X which enables the holding element 2 of an adjacent link 1 to be passed through.
  • a recess 5 which guides the saw band by means of running wheels or driving wheels driver elements attached to the band saw.
  • a diamond-tipped segment 6 at the end of the link 1 of the saw band pointing in the cutting direction.
  • a sliding surface 4 extending on both sides in the running direction of the saw band and an adjoining guide section 7. The sliding surface 4 and the guide section 7 serve as a form-fitting guide means on a guide rail attached to the band saw.
  • connection of two links 1 takes place in the manner shown in FIG. 2.
  • the holding element 2 of a link 1 is guided through the circular segment-shaped recess 3 and then brought into contact with the holding piece 3a.
  • the result is a form-fit connection that can withstand tensile loads and is articulated out of the cutting plane.
  • the holding element 2 and the recess 3 and the holding piece 3a are, as can be seen from FIG. 4, designed to be cranked in such a way that the
  • the neck of the T-shaped holding element 2 here forms a recess 8 for the
  • part of the recess 3 is formed as a recess 9 extending transversely to the running direction and approximately parallel to the cutting direction of the saw band, in which the holding element 2 on the
  • Holding piece 3a comes to the plant.
  • the cross section shown in FIG. 3 through a saw band shows that the thickness of the saw band denoted by b1 on the diamond segment 6 is greater than the thickness b3 present in the middle of the link 1 and also than the thickness b2 present on the guide section 7.

Abstract

L'invention concerne un ruban de scie pour une scie à ruban, une scie à ruban munie d'un ruban de scie selon l'invention et des éléments individuels (1) d'un ruban de scie selon l'invention. Un grand inconvénient des scies à ruban existantes est qu'un seul défaut dans un ruban de scie, par exemple une dent ébréchée, suffit à rendre nécessaire le remplacement de tout le ruban. L'invention vise donc à créer une scie à ruban qui présente une durée d'utilisation moyenne plus élevée d'un ruban de scie pour des coûts d'utilisation comparativement faibles et qui rend ainsi exploitables les avantages du sciage par scie à ruban. A cet effet, le ruban de scie selon l'invention est constitué d'éléments individuels (1), reliés entre eux et placés en sens de marche. L'invention concerne également les éléments individuels d'un ruban de scie selon l'invention et une scie à ruban munie d'un ruban de scie selon l'invention. Le ruban de scie selon l'invention présente l'avantage déterminant qu'il peut être démonté en ses éléments individuels (1).
