Definitions

  • the invention relates to a frame saw tang with frame saw blade which can be inserted into the frame saw tang by an insertion-insertion movement and carries strips fastened on both sides at the end edges, which extend from the toothed saw blade edge in the width direction of the saw blade over a partial width thereof and have supporting surfaces which extend support on counter surfaces of a frame saw fishing box, the strips being received inside the fishing box and the strips being able to be implemented 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.
  • a frame saw tang with frame saw blade of the type mentioned is known from AT-A-279 138. Rectangular strips are provided, which can be implemented by means of 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. For this purpose, the strips have a smaller dimension than the width of the saw blade.
  • the known device is disadvantageous in terms of handling, since due to the relatively long strips to the width of the saw blade, the push-in movement into the fishing box is difficult, a tedious alignment with regard to the insertion depth has to be carried out and because such saw blades with strips that are shortened compared to the saw blade width are very difficult strongly tend to vibrate. Such vibrations then require a very careful one Handling of the entire gate, in particular the cutting performance must be reduced. The operator can only continue working with sensitive handling.
  • a gang saw blade is known from AT-A-297 304, the strips of which are shorter than the saw blade width have an area which extends beyond the fishing pocket.
  • the fishing bag is designed to engage a slider rod.
  • a slider rod of this type cannot exert lateral clamping pressure on the load.
  • the strips on both sides of the saw blade are screwed outside the area beyond the fishing pocket.
  • the object of the invention is to provide a generic frame saw tang with frame saw blade which is more advantageous in use.
  • the strips have a length approximately corresponding to the remaining width of a maximally sharpened saw blade and one of the strips with its end face 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 corresponds approximately to the length of a bar and that the area of the fishing box facing the center of the saw blade is widened beyond the stop in the direction of the rear edge of the saw blade.
  • 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. These strips, which in their length essentially correspond to the remaining width of a maximally sharpened frame saw blade, require only one for the insertion-insertion movement very little free space. The strip-equipped saw blade can therefore be handled very well. The strips can be adjusted in the row of holes provided over the entire width of the frame saw blade in the direction of the back edge of the saw blade.
  • the exact insertion limit at both ends of the saw results from the fact that one of the strips, with its end face facing the saw blade rear edge, comes up against a stop of the frame saw fishing box, the distance from the front edge of the frame saw fishing box approximately corresponding to the length of the strips. Basically, a very large frame saw blade width can be assumed, which significantly increases the usage times. The short strip length has an economic impact on production.
  • the further structure is selected such that the gang 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.
  • 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. Taking into account the undercut of the support surface both on the bar and on the counter surfaces of the frame saw fishing box, a pressure component results with respect to the bars. This makes it practically possible to get by with a single screw pin, to which only one or two dowel-like centering pins entering the row of holes have to be assigned.
  • 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 start from the toothed edge 1 ′′′ of the saw blade.
  • the length ratio of bar to 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 ⁇ ligating.
  • 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 region facing the center of the saw blade (upper end of the saw blade 1 ') than in its region 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 level St coincides with the height of the counter surface 2 '.
  • the support surfaces 4 'of the strips 4 and the counter surfaces 2' of the fishing box 2 are undercut in opposite directions, so that a spreading tendency of the pocket walls forming the fishing box is effectively prevented. Rather, a Kratt component that contracts 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 subjected to pressure in the direction of the saw blade broad surface and is thus clamped.
  • 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.
