Definitions

  • the invention relates to a frame saw tang with frame saw blade, in which the saw blade can be inserted into the frame saw tang by means of the insertion-insertion movement, carries strips fastened on both ends at the end edges, starting from the toothed edge of the saw blade, only over part of the width of the saw blade and form support surfaces which are supported on inward-facing counter surfaces of the frame saw fishing box.
  • a frame saw tang with frame saw blade of this type is known from DE-PS 11 64 633.
  • the strips are interrupted by a recess to achieve a short insertion path and easier replacement of blunted frame saw blades.
  • the fishing box In the area of the pocket edge forming the counter surfaces, the fishing box has an opening which allows the remaining strips to pass through.
  • this is also disadvantageous in that the opening is filled with sawdust.
  • the forerunner mentioned therefore also provides coverage.
  • This consists of a block provided on both sides of the saw blade and extending parallel to the bar. Corresponding configurations are therefore very complex to manufacture and thus expensive. A complete shielding of the openings can also not be achieved, since the insertion-insertion movement requires a space between the block and the corresponding edge of the fishing box.
  • the object of the invention is to design a generic frame saw tang with frame saw blade in a technically simpler, more stable manner so that on the one hand there is a short insertion path, but on the other hand the need to provide special covers is eliminated.
  • a generic frame saw tang with frame saw blade of particularly increased utility value is created: the desired short insertion path is achieved by means of only short rails, which practically have the width of the fishing box.
  • the length of these strips which essentially correspond to the remaining width of a maximally sharpened frame saw blade, also migrate. They can be adjusted in the direction of the back edge of the saw blade in the row of holes provided over the entire width of the frame saw blade.
  • the exact insertion limit at both ends of the saw results from the fact that the end faces of the saw blade rear edge face the stop against a stop of the gang saw fishing box, the distance of which from the front edge of the saw saw fishing box corresponds approximately to the length of the lasts.
  • the further structure is chosen such that the frame saw fishing box has a greater width in its area facing the center of the saw blade than in its area facing the shaft.
  • the corresponding widening level coincides with the height of the counter surfaces of the frame saw fishing box.
  • the corresponding overhang carries the stop limiting the insertion depth.
  • an advantageous embodiment of the frame saw fishing box is made such that the support surfaces of the strips are stepped in such a way that a wing-like projecting strip section protrudes into the saw passage gap of the frame saw fishing box.
  • the frame saw fishing boxes 2 engaging at the ends 1 'of a frame saw blade 1 each continue in a shaft 3 which is used to fix the frame saw blade 1 in the frame frame with tensioning means (not shown).
  • 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 rear edge 111.
  • 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 111 and is designated by 10. The latter forms wing-like projections.
  • the widening level St decreases with the amount of Counter surface 2 'together.
  • 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 that pulls the pocket walls under load occurs.
  • 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 fastening 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 with its pocket inner walls the axial position of the centering pin 16, which may also have edge notches.
