Abstract
The utility model relates to a kind of noise reduction circular saw blade, and its saw bit matrix outer ring studs with sawtooth, and saw bit matrix is provided with dark teeth groove such as some grades, and saw bit matrix center is provided with center mounting hole, and described saw bit matrix processes a noise reduction teeth groove every dark teeth groove such as several grades.The degree of depth of described noise reduction teeth groove is etc. 1.5 times-3 times of dark gullet depth.The utility model by changing tooth depth and distribution, upset air vortex flow point when saw blade rotates from frequency, reduce the self-excited vibration having excited saw blade because air-swirl division, thus noise when reducing saw blade rotation.There is structure simple, handling ease, excellent noise reduction effect, good stability, life-span be long, be convenient to the advantage of producing.
Description
Technical field
The utility model relates to a kind of timber, metal, stone material cutting tool, especially a kind of noise reduction circular saw blade.
Background technology
Saw blade is widely used in the cutting processing of building materials, timber, metallurgy, mechanical processing industry because its manufacture is simple, easy to use, cutting efficient.During existing common saw blade work, due to the air-swirl of severe impact and vibration and generation, cause serious noise pollution.In order to solve problem of noise pollution, market has occurred low noise, the noise abatement saw blade of the manufacturers produce such as multiple pattern is German, Japanese, Italian, these manufacturers mainly add damping from silencing and damping groove and set about, and the extraordinary quieter material of the research also had does saw blade.Although these structures have certain vibration silencer function, its processing technology is complicated, and technological level requires high, actual production difficulty.
Summary of the invention
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, and provide a kind of structure simple, handling ease, good muffling effect, can prevent noise pollution, the change tooth depth noise reduction circular saw blade of good stability.
The technical scheme in the invention for solving the above technical problem is: a kind of noise reduction circular saw blade, its saw bit matrix outer ring studs with sawtooth, saw bit matrix is provided with dark teeth groove such as some grades, saw bit matrix center is provided with center mounting hole, it is characterized in that: described saw bit matrix processes a noise reduction teeth groove every dark teeth groove such as several grades.
The degree of depth of described noise reduction teeth groove is etc. 1.5 times-3 times of dark gullet depth.
Described noise reduction teeth groove is 90 degree, interval or 60 degree of distributions on saw bit matrix.
The utility model owing to being processed with a darker noise reduction teeth groove every dark teeth groove such as several grades on saw bit matrix, by changing tooth depth and distribution, upset air vortex flow point when saw blade rotates from frequency, reduce the self-excited vibration having excited saw blade because of air-swirl division, thus reduce noise when saw blade rotates.Against existing technologies, the utility model structure is simple, handling ease, have excellent noise reduction effect, good stability, life-span long, be convenient to the advantage of producing.
Accompanying drawing explanation
Here is that the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is the utility model composition structural representation.
Fig. 2 is the structural representation of another form of the utility model.
Label in figure is: 1. saw bit matrix, 2. sawtooth, 3. dark teeth groove such as grade, 4. noise reduction teeth groove, 5. center mounting hole.
Detailed description of the invention
As can be seen from Fig. 1, Fig. 2, a kind of noise reduction circular saw blade of the utility model, its saw bit matrix 1 outer ring studs with sawtooth 2, and sawtooth 2 is welded on saw bit matrix, and saw bit matrix 1 is provided with dark teeth groove 3 such as some grades, and saw bit matrix center is provided with center mounting hole 5.Above-mentionedly belong to prior art, repeat no more.
The utility model feature is: described saw bit matrix 1 processes a noise reduction teeth groove 4 every dark teeth groove 3 such as several grades.
The degree of depth of described noise reduction teeth groove 4 is etc. 1.5 times-3 times of dark teeth groove 3 degree of depth.
Described noise reduction teeth groove 4 is 90 degree, interval or 60 degree of distributions on saw bit matrix 1.
The utility model is processed with a darker noise reduction teeth groove every dark teeth groove such as several grades on saw bit matrix, by changing tooth depth and distribution, upset air vortex flow point when saw blade rotates from frequency, reduce the self-excited vibration having excited saw blade because of air-swirl division, thus reduce noise when saw blade rotates.The utility model structure is simple, handling ease, have excellent noise reduction effect, good stability, life-span long, be convenient to the advantage of producing.Be applicable to various saw blade.
Claims (3)
