Technical Field

The invention relates to the technical field of saw blades, in particular to a five-tooth circulating band saw blade.

Background

The product kerf is big when the existing band saw blade cuts, the finish of the wood section is rough, the subsequent polishing allowance is large, the wood waste is increased, the four-tooth circulation band saw blade provided by the patent 201820100855.5 has four teeth on the same horizontal plane, the structure has slow cutting speed of the saw teeth when in work, the chip cleaning teeth are flat teeth, and the cut material section is rough.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a band saw blade with a five-tooth cycle structure, which is reasonable in structure and good in using effect.

In order to achieve the purpose, the technical scheme provided by the invention is as follows: a band saw blade with five-tooth circulation comprises a band saw body made of hard alloy, wherein a plurality of groups of teeth are uniformly distributed on the edge of the band saw body, adjacent groups of teeth are connected end to form circulation, and each group of teeth consists of a road-cutting tooth, a first single-cutting tooth, a second single-cutting tooth, a first chip-removal tooth and a second chip-removal tooth which are sequentially arranged; the tooth height from the road marking teeth to the second chip removal teeth is reduced in sequence, the first single cutting teeth and the first chip removal teeth incline towards the left side of the advancing direction of the band saw body, the second single cutting teeth and the second chip removal teeth incline towards the right side of the advancing direction of the band saw body, and a cutting area is formed between the outer edge of the first single cutting teeth and the outer edge of the second single cutting teeth.

The inclined horizontal width of the first chip removal tooth and the second chip removal tooth is smaller than the width of the cutting area.

One side of the scribing teeth in the advancing direction of the band saw body is triangular, and the tip of the triangle is located in the advancing direction of the band saw body.

The right side of the first chip removal tooth in the advancing direction of the band saw body is turned to form a left cutting surface, and the tip of the left cutting surface is turned to form a left flat tooth.

The left side of the second chip removal tooth in the advancing direction of the band saw body is turned to form a right cutting surface, and the tip of the right cutting surface is turned to form a right flat tooth.

After the scheme is adopted, the middle of the wood to be processed is guided in the direction of the road-marking teeth, the first single cutting tooth and the second single cutting tooth cut the wood, and then the first chip-removing tooth and the second chip-removing tooth cut the two sides of the wood, so that the smooth section is ensured. The saw blade is not easy to be blocked when cutting, the saw blade is not easy to break and the service life is prolonged by arranging the saw blade from high to low.

Detailed Description

The invention will be further described with reference to the accompanying drawings, in which preferred embodiments of the invention are: referring to the attached drawings 1 and 2, the band saw blade with five-tooth circulation in the embodiment comprises a band saw body 1 made of hard alloy, a plurality of groups of teeth are uniformly distributed at the edge of the band saw body 1, adjacent groups of teeth are connected end to form circulation, and each group of teeth consists of a road-marking tooth 2, a first single cutting tooth 3, a second single cutting tooth 4, a first chip removal tooth 5 and a second chip removal tooth 6 which are sequentially arranged; the tooth height from the path-cutting teeth 2 to the second chip removal teeth 6 is reduced in sequence, the first single cutting teeth 3 and the first chip removal teeth 5 incline towards the left side of the advancing direction of the band saw body 1, the second single cutting teeth 4 and the second chip removal teeth 6 incline towards the right side of the advancing direction of the band saw body 1, and a cutting area is formed between the outer edge of the first single cutting teeth 3 and the outer edge of the second single cutting teeth 4. The horizontal width of the inclination of the first chip removal tooth 5 and the second chip removal tooth 6 is smaller than the width of the cutting area. One side of the path-drawing teeth 2 in the advancing direction of the band saw body 1 is triangular, and the tip of the triangle is positioned in the advancing direction of the band saw body 1. The right side of the first chip removal tooth 5 in the advancing direction of the band saw body 1 is turned to form a left cutting surface, the tip of the left cutting surface is turned to form a left flat tooth, and the width of the left flat tooth is two fifths of the total width of a cutting area. Turning on the 6 left sides of the second chip removal tooth of 1 direction of advance of band saw body forms right cutting face, and right cutting face tip is turned into right side flat tooth, and right side flat tooth width is two fifths of total width of cutting area, and the during operation draws the way tooth to leading to in the middle of the timber that needs processed, and first single cutting tooth, second single cutting tooth cut timber, then first, second chip removal tooth carry out the smear metal to both sides, guarantee that the section is smooth.

The positions of the first single cutting tooth 3 and the second single cutting tooth 4 can be interchanged, and the positions of the first chip removal tooth 5 and the second chip removal tooth 6 can be interchanged.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that the changes in the shape and principle of the present invention should be covered within the protection scope of the present invention.
