Definitions

  • the invention relates to a saw chain for motor chainsaws for cutting hard objects such as walls made of brick, stone or concrete.
  • Motor chain saws are particularly known from woodworking. They basically consist of an elongated guide bar (the blade) and a saw chain running around the outside of the guide bar. These saw chains usually consist of an alternative arrangement of cutting links and connecting links, the cutting links each having a saw tooth. Such saw chains are, however, not or only insufficiently suitable for sawing hard objects such as walls made of brick, stone or concrete.
  • a saw chain for motor chain saws for cutting hard objects such as walls made of brick, stone or concrete
  • one or more of the chain links being provided with cutting bodies, characterized in that the cutting bodies are each connected to a cutting body support, which in turn is connected to the chain link (cutting link).
  • These cutting bodies are thus provided instead of the saw teeth.
  • the cutting bodies are preferably hard-coated with diamond, corundum, boron nitride or the like or contain these particles.
  • the cutting bodies are arranged on the cutting members.
  • the cutting member or the cutting body has a cutting body carrier.
  • the cutting bodies are preferably attached to the cutting members or the cutting body supports by sintering or soldering.
  • the cutting body support can either be an angled part bent by the cutting member or an attached support plate.
  • a dispenser nose is preferably arranged in front of and / or behind the cutting member, which is preferably made in one piece with the cutting member and thus consists of the same material. The dispenser nose can sit on the same cutting link or on one of the front or rear chain links.
  • the cutting bodies can be arranged on the connecting links.
  • Each cutting body is preferably fastened on both legs of the connecting member, a carrier plate also being provided here as the cutting body carrier.
  • dispenser noses are also preferably provided here, in particular in front of the cutting body, in order to protect it from breaking out.
  • the attachment is also preferably done by soldering.
  • 1 to 3 show a first embodiment variant in mutually associated cracks.
  • 4 to 6, 7 to 9 and 10 to 12 show three further embodiment variants in cracks which are also associated with one another.
  • each saw chain consists of a succession of cutting links and connecting links.
  • two cutting bodies 1 sit on the cutting member 2 along the outer edge 7.
  • the cutting member 2 comprises, in a known manner, the foot 3, which guides each cutting member in the guide rail of the motor chain saw and on its throat 4 in the usual manner Way attacks the drive pinion. With 5 the rivet holes are designated, which serve the connection with the subsequent chain links, in particular the connecting links.
  • the hard coating 6 extends both over both cutting bodies 1 and over the outer edge 7 of the cutting member.
  • the cutting element itself serves as a cutting body carrier.
  • the cutting member 2 has a carrier plate 8 along the outer edge 7, which is soldered or welded to the cutting member 2 or firmly connected by other means.
  • a continuous cutting body 1 with the hard coating 6 is seated on the carrier plate 8.
  • Dispenser lugs 9 extend in front of and behind the cutting body 1. These dispensing lugs 9 are integral with the cutting member 2 and serve for better fastening of the cutting body and also for protection against breaking out. With continuous abrasion of the cutting body, the dispenser nose is also removed, so that its height always adapts to the layer thickness of the cutting body.
  • a cutting body carrier is formed by two mutually bent angle parts 10. Dispenser noses 9 are formed in that 10 small tabs are bent up from the angular parts.
  • An additional carrier plate 8 is shown in dashed lines and is preferably used.
  • the connecting member 11 consists of two legs 12, which receive the ends of the cutting member 2 between them.
  • the link and cutting link are each pivotally connected to one another by a rivet 13.
  • the attachment of the cutting body 1 takes place on top of both legs 12 of the connecting member.
  • the connecting links or their legs 12 can form dispenser noses which are raised upward, as was the case in the previously described exemplary embodiments and is indicated by dashed lines in FIGS. 10 and 11.
  • the attachment of the cutting body on the carriers such. B. the cutting members 2, the carrier plates 8 or the angular parts 10 or the legs 12 of the connecting members is preferably done by soldering. During the soldering process, it is preferred to work under protective gas or in a liquid bath and to cool in order to prevent the carrier material from becoming brittle.
  • the cutting links and connecting links consist, for example, of high-strength steels, such as those used for saws.
  • the cutting bodies either consist of hard metal with coatings of diament, corundum, boron nitride or similar materials, or are sintered bodies which are provided with the hard material particles in layers or over the entire cross section.
  • the saw chains according to the invention are distinguished by long cut resistance even with hard stone or concrete materials.
  • the arrangement of the cutting body on a carrier plate as a cutting body carrier according to the invention is of particular importance for the strength of the fastening on the chain link.
  • the cutting body can thus be sintered onto the carrier plate. Thereafter, the carrier plate can be soldered onto the chain link in a gentle manner without damaging the sintered body, which would be the case with direct soldering.
