Definitions

  • the invention relates to a hinge for tensioning frame saw blades according to the preamble of the claim.
  • DE-A-3828030 discloses fishing for clamping frame saw blades for sawing stone blocks, which have a cross piece at one end, which is supported against the machine frame or a hydraulic frame saw tensioner and which has a rivet connection or hole at its other end area for receiving the Has connecting bolt between the hinge and saw blade, the hinge has a greater width in this area and the connection point is arranged above the shaft center line in order to bring about a vertical force in the tensioned state, which is directed counter to the feed force. This extends the engagement or cutting period and protects the frame crossbar and the hinges.
  • the invention has for its object to provide a system in which the fishing shafts have the same width for cost reasons and still achieve a shear force that is directed opposite to the feed force.
  • the fishing / gate frame system has fishing rods with the same fishing rod width, the fishing shafts being arranged obliquely to the longitudinal axis of the saw blade in the clamped state such that their ends facing away from the saw blade are arranged closer to the stone block to be cut than their ends connected to the saw blade.
  • FIG. 1 shows a system according to the invention with the hinge (6) with the resulting fishing force (5) between the frame cross members (1) and the support cam (7) causing the inclined position.
  • the force (G) caused by the inclination of the hinges is opposed to the feed forces (V).
  • FIG. 2 shows a further system according to the invention, in which the inclined position of the resulting fishing force (5) in the rod (6) is brought about by the inclined position of the fishing traverses (2).
