Definitions

  • the present invention relates to a circular saw in which a plurality of cutting tips are joined to an outer periphery of a base metal, the sound pressure level of noise generated during cutting can be reduced, and the cutting tips can be easily polished by an automatic polishing machine. It relates to a circular saw to be obtained.
  • Circular saws with a large number of cutting tips joined to the outer periphery of a circular base are used for rotary cutting (hereinafter called cutting) of various materials (hereinafter referred to as work material) such as wood, metal, synthetic resin, etc. .
  • the noise generated during cutting depends on the material of the work material and its hardness, softness or shape. I'm making it worse.
  • the interval (pitch) between adjacent cutting tips is uniform, and when cutting, the work material and each cutting tip Is constant. For this reason, during the cutting of the work material, a sound of a specific frequency is generated loudly, which is a source of noise.
  • the pitch refers to the spacing between adjacent tooth edges of a saw tooth in one chip group (A, B, C,%) (Timber Processing Glossary Dictionary Japan Wood Society Machine Processing Study Group). Say.
  • the pitch of the cutting tip is the same, a high frequency sound of a specific frequency is generated during cutting, which causes noise, so in order to improve this, the pitch of the cutting tip is intentionally changed.
  • Irregular circular saws have been proposed. For example, with regard to the cutting tips to be joined to the outer circumference of the circular base, if one set of teeth is arranged in sequence with five tips, the four cutting tips will have the same pitch in one set (5 tips). The other one of the cutting tips has a circular saw in which the pitch with respect to the other cutting tips is changed. This can be evaluated in that the sound generated during cutting does not have a specific frequency and the peak frequency is dispersed, which is effective in reducing noise during cutting.
  • An automatic polishing machine is generally used for cutting and re-polishing a cutting tip in the circular saw. That is, the circular saw mounted on the index shaft of the automatic polishing machine is rotated by one pitch at a time corresponding to the number of cutting chips, and the chips are polished with a grindstone rotating at a fixed position. This operation has no problem for the automatic polishing machine as long as the pitch of each cutting tip in the circular saw is constant.
  • the pitch of the cutting tip described above is irregular, the irregular pitch must be numerically controlled by the control device of the automatic polishing machine, and in some cases, the numerical control is out of the possible range. There is a problem that it cannot be dealt with by an automatic polishing machine.

  • the pitch of the chips in each chip group is such that the pitch between the last chip and the first chip is an arbitrary value, and the others are set equal.
  • a pitch dimension is different between an equal pitch of at least one chip group and an equal pitch of another chip group in the two or more chip groups,
  • the gist is that three or more chips of the same chip group are not continuously arranged in the outer peripheral direction.
  • the pitch of each cutting chip is simply stored in the automatic polishing machine for each chip group. Automatic polishing can be achieved without significant numerical changes. Further, since three or more chips of the same chip group are not continuously arranged in the outer peripheral direction, the chips of each chip group are dispersed throughout the circular saw, so that the pitch of adjacent chips is not biased.
  • At least one of the chip groups has the same pitch.
  • the gist is that two chip groups are provided.

Abstract

Selon l'invention, en ce qui concerne de multiples pointes de coupe liées sur la périphérie d'un métal de base de scie circulaire, il est possible de réduire le bruit lors de la coupe d'une pièce à travailler en faisant varier le pas entre des pointes adjacentes. Cependant, un problème existait selon lequel, en fonction du pas des pointes de coupe, lesdites pointes ne pouvaient pas être polies au moyen d'une machine de polissage automatisée. La solution selon l'invention porte sur une scie circulaire (10) obtenue par liaison du nombre requis de pointes de coupe (14) sur la périphérie d'un métal de base (12), ladite scie circulaire étant conçue de telle sorte qu'un grand nombre de pointes de coupe (14) sont disposées en tant qu'au moins deux groupes de pointes (A, B, …) agencés en réseau sur la périphérie de la scie circulaire (10) ; le pas de chaque groupe de pointes (A, B, …) est réglé de façon à être le même, à l'exception du pas entre la dernière pointe (Am, Bn, …) et la première pointe (A1, B1, …) ; et le pas d'au moins l'un desdits groupes de pointes (A, B, …) est amené à différer du pas desdits autres groupes de pointes (A, B, …).
