Definitions

  • the invention relates to a frame saw tang with frame saw blade, which can be inserted into the frame saw nails by an insertion-insertion movement and carries strips fastened on both sides at the end edges, which extend from the toothed edge of the saw blade in the width direction of the saw blade and have support surfaces which are located on counter surfaces of a frame saw - Support the fishing box.
  • Such a frame saw fishing is known from DE-A-2844329.
  • the strips between the saw blade extend essentially over the entire width of the saw blade and carry on their edges facing away from the saw blade approaches which protrude into a fishing box.
  • the approaches have support surfaces that are supported on counter surfaces in the fishing box.
  • This construction is complex because of the connection between the last and the fishing box.
  • the known construction does not provide for adjustment of the strips in the width direction of the saw blade. The screws and pins that clamp the bars against the saw blade are exposed to the outside and must be secured against falling out.
  • the strips located outside the fishing box extend essentially over the entire width of the saw blade, which has a number of holes, in order to be able to move the strips towards the rear edge of the saw blade. From their central area there are lugs with support surfaces that grip a support profile on a hinge from the outside. This construction is also comparatively complex. Which carries the saw blade. bars are not shielded from the outside.
  • the invention has for its object to provide a generic gang saw with manufacturing technology and handling simplified construction in which, despite the feasibility of the strips, the devices creating the connection between saw blade and fishing box are essentially shielded from the outside.
  • the strips are received in the interior of the fishing box, that the strips can be implemented in a manner known per se in a row of holes extending across the entire width of the saw blade in the transverse direction to the rear edge of the saw blade and that the strips with a about the remaining width of a maximally sharpened frame saw blade corresponding lengths with their end faces facing the saw blade rear edge can be brought into contact with a stop provided in the fishing box, the distance from the front edge of the fishing box corresponding somewhat to the length of a bar.
  • the strips therefore only have a length which essentially corresponds to the remaining width of a maximally sharpened frame saw blade and are accommodated with their supporting surfaces essentially in the frame saw fishing box with the mating surfaces provided therein.
  • the strips can be adjusted in the direction of the rear edge of the saw blade in the row of holes provided over the entire width of the frame saw blade.
  • the exact respective slide-in limitation results from the fact that the strips with their end faces facing the saw blade rear edge step against a stop in the fishing box, the distance from the front edge of the fishing box corresponds approximately to the length of the strips. This ensures that the strips are always inside the.
  • the length of the strips does not have to be specifically matched to the width of the frame saw blade, saw blades with a substantial length can in principle be provided, which requires a corresponding extension of the useful life.
  • the shortened strips have a comparatively simple structure, which not only favors warehousing but also manufacturing. Since the strips are completely accommodated in the fishing box, the axial position of the pins which produce the connection between the saw blade and the strips can be fixed in a simple manner through the inner walls of the fishing box.
  • the fishing box can be widened at the area facing the center of the saw blade.
  • the widening level can lie approximately at the level of the counter surfaces of the fishing box and can support the stop.
  • An advantageous development of the invention is further characterized in that the strips are stepped in such a way that a projecting strip section protrudes into the passage gap for the saw blade of the fishing box. Taking into account the support surfaces on the strips, which are engaged by the counter surfaces of the fishing box, this results in a pressure component with respect to the strips. Therefore, according to another development of the invention, it is sufficient if a central screw pin braces the strips fixed in position by one or more adjacent centering pins against the saw blade.
  • the frame saw fishing boxes 2 engaging at the ends 1 'of a frame saw blade 1 are each continued in a shaft 3 which is not closer to The clamping means shown serves to fix the frame saw blade 1 in the frame.
  • the gang saw blade has a row of holes running parallel to these in the region of the end edges and consisting of holes 5 which are at the same, narrow distance from one another.
  • the strips 4, which correspond approximately in length to the remaining width of a maximally sharpened frame saw blade 1, can accordingly be gradually displaced in the direction of the saw blade back edge 1 '.
  • Such relatively short strips have the advantage of a small insertion depth, which facilitates the assignment of the frame saw blade or its removal from the register.
  • the strips 4 start from the toothed edge 1 ′′ of the saw blade.
  • the length ratio of the strip to the frame saw blade width is approximately 1: 2.
  • each gang saw fishing box 2 has a stop 7 at the end of the saw passage gap 6 thereof.
  • the end face 8 of one of the strips 4 arranged in pairs occurs in the insertion direction x.
  • the distance of the stop 7 from the front edge 9 of the frame saw fishing box 2 corresponds approximately to the length of the strips 4.
  • the gang saw fishing box 2 has a greater width in its lower area facing the center of the saw blade (upper saw blade end 1 ') than in its area facing the shaft 3.
  • the widening zone extends in the direction of the saw blade rear edge 1 "and is designated by 10. The latter forms wing-like projections.
  • the widening step St coincides with the height of the counter surface 2 '.
  • a horizontal surface forming the stop 7 extends from its top side, which runs parallel to the end edge aligned pin or cotter pin.
  • the support surfaces 4 'of the strips 4 and the counter surfaces 2' of the fishing boxes 2 are undercut in opposite directions, so that a spreading tendency of the pocket walls forming the fishing box is effectively prevented. Rather, a force component occurs which pulls the pocket walls together under load.
  • This is also used in the sense of supporting the attachment of the strips 4, for which the strips 4 are stepped in such a way that a wing-like protruding strip section 11 resting on the broad sides of the saw blade remains, which protrudes into a corresponding recess 12 in the saw passage gap 6.
  • the strip section 11 is pressure-loaded in the direction of the broad saw blade surface and is thus clamped.
  • an approximately central screw pin 13 is sufficient for the attachment of the strips 4, which, penetrating a passage opening 14 of the one strip 4 and one of the holes 5, engages in an internal thread 15 of the opposite strip 4.
  • the head of the screw bolt 13 is designed as a countersunk head with an internal polygon.
  • the screw pin 13 is further flanked by two centering pins 16 which, also penetrating the holes 5 of the row of holes, also define the strips 4.
  • the fishing box itself secures the axial position of the centering pin 16 with its pocket inner walls, which can also have edge notches.
