Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 This invention relates to a saw used when cutting an object such as wood.

[0002]

[Prior art]

 Conventionally used saws are of two types: a horizontal saw with a saw tooth row consisting of horizontal teeth and a vertical saw with a saw tooth row consisting of vertical teeth. There is a double-edged saw that uses horizontal and vertical grinding teeth independently on both blades to separately use the horizontal and vertical grinding of the material to be cut. There are no saws in rows.

[0003]

[Problems to be solved by the device]

 In the conventional saw described above, since the cutting field of the object to be cut B is determined by the shape of the saw teeth, the direction of the grain is not constant like plywood and laminated wood, which have recently become the main force of construction materials. There is no one suitable for cutting things like vertical and horizontal crossings, and there is a need for a saw suitable for cutting these. Furthermore, when the details of these horizontal and vertical teeth are examined, Is a tool that cuts an object to be cut with a plow-shaped cutting blade, so it is suitable for cutting soft parts along wood grain with a constant material and for cutting aluminum alloy, etc. On the other hand, when cutting at a right angle or near a right angle, it is difficult to make a smooth cut because the saw teeth are caught in the grain. In addition, since the saw teeth are sword-shaped ruled blades for horizontal teeth, the wood grain is cut at a right angle to the wood grain and the two grain lines are attached to the cut object. Since the upper sloping blade of each sawtooth is used to cut the gap between the cuts, this cutting takes time and is difficult to cut. In view of the above, it is an object of the present invention to provide a saw that is well cut down for vertical grinding, horizontal grinding, plywood, etc. of a material to be cut.

[0004]

[Means for Solving the Problems]

In order to achieve the above-mentioned object, this invention comprises a saw tooth row 3 provided on the blade body portion 2 of the saw blade 1 with lateral grinding teeth 3 ₁ and longitudinal grinding teeth 3 ₂ and a ruled line with the lateral grinding teeth 3 ₁ . It intended to facilitate the cutting opening of the groove E followed by out scraped out of the grooves E while digging the cutting portion D between Setsujo C and C of the two muscle that he vertical挽歯3 _2, In this saw tooth row 3, lateral grinding teeth 3 ₁ and longitudinal grinding teeth 3 ₂ are alternately arranged. Further, the position of the top blade 3 ₂₁ of the longitudinal grinding teeth 3 ₂ constituting the saw tooth row 3 is the lateral grinding teeth 3 ₁ There the position lower than the position of the Tenha 3 _11, moreover vertical挽歯3 edge line 3 _{22 2} of the top blade 3 ₂₁ perpendicularly intersect with respect to the plate surface of the blade body portion 2 of the saw body 1 edge line 3 ₂₂ There and that a cutting method Sakusato鉋simultaneously cutting the entire width of the cutting portion D, the vertical挽歯3 ₂ as two pair, this two vertical挽歯3 each top blade ₂ 3 ₂₁ each edge line 3 ₂₂ counterclockwise together each edge line 3 ₂₂ to the plate surface of the blade portion 2 of That an inclined edge which is inclined toward the direction considered.

[0005]

[Embodiment of device]

This invention will be described with reference to the accompanying drawings. The horizontal grinding teeth 3 ₁ constituting the saw tooth row 3 are saw teeth having an upper eye called Edo mesh, and the vertical grinding teeth 3 ₂ are saw teeth called rattle eyes. which longitudinal挽歯3 ₂ this became a Tenha 3 ₂₁ intersects at right angles to the plate surface to the plate surface of the blade body portion 2 of the saw body 1 to be cut was such that only鉋掛and vertical挽歯3 ₂ to two pair and inclined at an inclination angle of the edge line 3 ₂₂ of the top blade 3 ₂₁ of each longitudinal挽歯3 ₂ about a substantially 10 ° staggered directions relative plate surface of the blade portion 2 sloping It is a blade. Nao, what is the horizontal挽歯3 ₁ embodiment of the present invention is Edo eyes may be a sawtooth called the other Ibarame, short limited to embodiments as long as easy serrated cutting of wood grain Not. Although also examples in the vertical挽歯3 ₂ is Gagari eyes, may be the other horticultural states th not short ones longitudinal sawing be limited to the examples as long as easy sawtooth, Moreover, the the vertical挽歯3 ₂ of the top blade 3 ₂₁ of edge line 3 ₂₂ Tenha 3 ₂₁ edge line 3 ₂₂ right angle plate surface of relative plate surface of the blade body portion 2 of the saw body 1 in the embodiment to that intersect, but the edge line 3 ₂₂ indicates a material obtained by the inclined edge of inclined obliquely with an inclination angle of approximately 10 degrees relative to the plate surface, the rather limited to this inclination also example The inclination angle may be suitable for cutting depending on the material of the cut material.

As for the combination of the horizontal and vertical teeth forming the saw tooth row, in the embodiment, two horizontal and two vertical ground teeth are shown. If the blade line of has no inclination angle, it may have two horizontal grinding teeth and one vertical grinding tooth, in short, the sawtooth row composed of horizontal grinding teeth and vertical grinding teeth. The present invention is not limited to the examples as long as the best sharpness can be exhibited.

The difference in tooth height between the lateral grinding teeth 3 ₁ and the longitudinal grinding teeth 3 ₂ that constitute the saw tooth row 3 also changes because of the material of the material to be cut and the size of the saw teeth. The numerical values are not constant, and when forming the groove E in the cutting operation of the material to be cut, the longitudinal grinding tooth first marks the double streak, C, and after a short delay, the horizontal grinding tooth has the double streak. It is only necessary to be able to scoop off the cutting portion D between C, and it is necessary to make a very small difference in the numerical values, which should be determined according to the material of the material to be cut. Anything can be used as long as it can show the best sharpness for the object.

[0008] The edge line 3 ₂₂ vertical挽歯3 ₂ of the top blade 3 _21, which edge line 3 ₂₂ to the plate surface of the blade portion 2 crosses the plate surface at right angles to state lateral挽歯3 ₁ with a soft material suitable for cutting an object to be edged tool such as a timber, horizontal挽歯3 ₁ is double muscle was Egai ruffled the cutting portion D between the Setsujo C of Tate挽tooth 3 ₂ edge line 3 ₂₂ The entire blade width comes into contact at the same time, and this portion is cut to scrape out the generated grinding powder to the outside of the groove E and discharge it to cope with the cutting of the saw. From such a edge line 3 ₂₂ to be cut object it is intended to cut them in contact with the cutting portion D full blade width from that good separation of挽粉in cutting things soft material transverse挽歯only horizontal挽鋸Good cut-off to the cut object.

[0009] In the edge line 3 ₂₂ vertical挽歯3 ₂ of the top blade 3 _21, vertical挽歯3 ₂ each longitudinal挽歯3 ₂ of the edge line 3 ₂₂ saw body 1 of the blade of which the two pair to that is inclined toward the surface side of the part 2, which is inclined toward the rear surface side of the blade section 2, of the two muscle was made cut in the switching object B by transverse挽歯3 ₁ Setsujo The blade line 3 ₂₂ does not cut the cutting portion D at a time between C, and the blade line 3 ₂₂ cuts little by little from the higher side of the blade line 3 ₂₂ to the lower side, so that there is a gap between the two streaks. The saw makes it possible to cut lightly without requiring a large grinding force, and the saw facilitates the cutting of the material to be cut. The saw having such vertical挽歯3 ₂ cleavage of such stiff material timber shows a good sharpness could adapt to the cleavage of course that soft ones.

[0010] As described above, in the sawtooth row 3 comprising a vertical挽歯3 ₂ teeth height of the tooth height than the lateral挽歯3 ₁ of tooth height from was slightly deteriorated when trying to cut the object to be cut was First, the group of lateral teeth 3 ₁ cuts into the material to be cut B and attaches a double-stripe cut C. Then, after a little delay, the group of longitudinal teeth 3 ₂ cuts between the cut C and the cut C. Since it cuts D, the saw tooth has a large burden as in the case of a conventional horizontal saw with only horizontal teeth, which serves both to form the slit and to cut the cut portion between the slits. Unlike the horizontal grinding, the horizontal grinding teeth 3 ₁ and the vertical grinding teeth 3 ₂ share scoring and cutting, respectively, so that quick cutting is performed. It is also possible to solve this problem by eliminating the problem of slow cutting down and making the cut easier to bend when using a horizontal saw along the wood grain. Instead of making a straight cut quickly, the saw also makes it easy to cut plywood and laminated wood where the grain intersects, or cut diagonally to the grain.

[0011]
