Definitions

  • the invention relates to a saw blade for a hand saw with a trained on the longitudinal side row of set teeth.
  • tooth shapes that are used for manually operated saws or motorized saws with alternately reciprocating saw blade.
  • tooth forms of longitudinal saw blades are among others: the AV tooth shape, the KV tooth shape, the M tooth shape, the NU tooth shape, the NV tooth shape, the PV tooth shape, which tooth shape types, for example, in the Lueger Lexicon of Technology , R hindert, vol. 2, 1975, page 436.
  • the AV tooth is defined by a symmetrical triangular tooth.
  • the KV tooth is defined by an unbalanced open-space tooth body, the tooth body extending from a reinforced broad tooth base along a second flank which forms a so-called second flank angle with respect to a saw blade normal.
  • a second, flatter edge which defines a first flank angle relative to the saw blade normal, adjoins the second tooth flank. From the tip of the tooth body extends at the first and second edge opposite chip edge in a rake angle relative to the saw blade normal continuously linearly to the tooth base.
  • the so-called M-tooth has the shape of an M, which is formed at the top of a small central groove.
  • the M-tooth is designed with equilateral parallel cutting edges.
  • the NU tooth shape is determined by an asymmetrical triangular tooth shape with a flat extended tooth gap between each two adjacent teeth.
  • the NV tooth shape has the same shape as the NU tooth shape, but lacks the extended tooth gap between two teeth.
  • the PV tooth shape is also defined by an asymmetrical triangular tooth, but with a curved free surface and a strongly rounded tooth gap bottom.
  • the saw teeth are usually limited in all tooth shape types, d. H. alternately bent to the right or left.
  • saw blade is provided with a formed on a longitudinal side row of set teeth in a KV tooth shape, which is defined by a first flank angle, a second flank angle and a rake angle, wherein the first flank angle between about 50.0 ° to 54.0 ° , the second flank angle between about 14.0 ° to 16.0 ° and the rake angle between about 11.2 ° to 14.0 °
  • the best sawing results were achieved when an angle combination of about 53 ° to 54 °, preferably about 53.6 °, for the first flank angle, about 14 ° to 15 °, preferably about 14.6 ° was set for the second flank angle and about 13 ° to 14 °, preferably about 13.3 ° for the rake angle.
  • first flank angle between about 50.0 ° and 51.0 °, preferably at about 50.7 °
  • second flank angle between about 15.0 ° and 16.0 °, preferably at about 15.7 °
  • the rake angle between about 12.0 ° and 13.0 °, in particular at 12.8 °, combined in a saw blade.
  • the best test results were found when for the first flank angle about 53.0 ° to 54.0 °, preferably about 53.2 °, for the second flank angle about 13.5 ° to 14, 5 °, preferably about 14.0 ° and for the rake angle about 11.2 ° to 12.0 °, preferably about 11.8 ° is selected.
  • the above dimensions for the first flank angle, the second Flarikenwinkel and the rake angle of a KV tooth shape has always provided excellent cutting results regardless of the length dimensioning of the tooth itself and the zusausgenden wood material.
  • the best sawing results are achieved when the pitch of the respective row of teeth in a range between two to four teeth per inch (25.4 mm), in particular between about 2.3 to 3.4 Teeth per inch, preferably about 3.2 or 2.5 teeth per inch, is determined.
  • the value 2.5 turned out for an optimum tooth pitch.
  • the respective saw was clamped in a dynamometer to determine which sawing force is applied to each saw type in the direction of advance of the saw blade and in the vertical transverse direction.
  • a meter was assigned to the workpiece, which meter determines the amount of stress on the weight of the shaved by the saw blade shavings or by the removed from the sawing material volume. It is clear that essentially the same tool material, in particular the same tool steel, having substantially identical surface finish was used for each of the saw blades to be tested.
  • the saw blade sold under the brand name Sharptooth 20-065 by the above mentioned company Stanley Works and has a rake angle of 15.0 °, a first flank angle of approx. 56.0 ° and a second flank angle of approx 17.0 °, with the second embodiment according to the invention - first flank angle between about 50.0 ° to 51.0 °, in particular about 50.7 °, second flank angle at about 15.0 ° to 16.0 ° , In particular about 15.7 ° and the rake angle at about 12.0 ° to 13.0 °, especially at 12.8 °, compared. Both saws showed approximately the same tooth pitch.
  • the desired degrees of angularity are readily determinable with known precision measuring techniques, such as laser technology, the touch probe method, the so-called co-ordinate measuring method, etc.
  • the invention also relates to a hand saw with a saw blade according to the invention.
  • the saw blade 1 comprises a series of set teeth 3 in a KV tooth form, which is defined by a first flank angle ⁇ , a second flank angle ⁇ and a rake angle ⁇ .
  • the first flank angle ⁇ is given by the circumferential area between a first flank 5 of the tooth 3 and the saw blade normal N
  • the second flank angle ⁇ by the peripheral area between the second flank 7 of the tooth 3 and the saw blade normal N
  • the rake angle ⁇ by the peripheral area between the Chuck edge 9 of the tooth 3 and the saw blade normal N.
  • a value of 13.3 ° is provided for the rake angle ⁇ , a value of 53.6 ° for the first flank angle ⁇ , and a value of 14.6 ° for the second flank angle ⁇ .
  • the KV tooth shape is the rake angle ⁇ at 12.8 °, the first flank angle ⁇ at 50.7 ° and the second flank angle ⁇ at 15.7 °.
  • the pitch is set at 2.54 teeth per inch.
  • the rake angle ⁇ is set at 11.8 °, the first flank angle ⁇ at 53.2 ° and the second flank angle ⁇ at 14 °.
  • a tooth pitch of 3.2 inches is set.
