Abstract
A saw blade, rounded, with saw teeth arranged on the circumference. Body of the saw blade is opened with joint cuttings that are evenly arranged along a concentric circle or the saw blade. The joint cuttings are S-shaped, six in number. The utility model applies laser joint cuttings on saw blade to reduce saw vibration, thus to reduce noise. The utility model has a simple structure and is easy to operate, with reduced energy consumption and manufacture cost.
Description
One, technical field
The utility model relates to a kind of saw blade.
Two, background technology
Can produce big noise when adopting the portable cutting machine that has saw blade at present now to cut building materials, stone material, noise is the most significant to operator's harm to be that hearing descends, long-term work under the noise circumstance through being everlasting more than 100 decibels produces the noise deafness probability and can reach 19%; Noise also can damage operator's central nervous system except reducing operator's hearing, and automatic nervous system and cardiovascular system aspect cause dizziness, headache, and brain rises, insomnia, dreaminess, tinnitus, weak, failure of memory is felt sick the cardio palmus shape.
Three, summary of the invention
The purpose of this utility model is to solve shortcomings such as the noise that exists when existing saw blade uses is big, harmfulness is big, can reduce the saw blade of noise when a kind of the use is provided greatly.
For this reason, the utility model is taked following technical scheme:
A kind of saw blade, described saw blade are circular, and sawtooth is distributed on the circumference, has joint-cutting on the described saw bit matrix.
Further, described joint-cutting evenly distributes on the concentric circles of saw blade circumference.The bearing of trend of described joint-cutting and concentrically ringed circumference are unanimous on the whole, and even distribution at this moment is meant that the size of joint-cutting is identical as far as possible, the symmetry as far as possible of arranging of joint-cutting.
Further, described joint-cutting is distributed on the same concentrically ringed circumference.
Described joint-cutting is S-type.
Described joint-cutting is six.Also can according to the saw blade size maybe needs be divided into 4,8,9.
Saw blade described in the utility model has following advantage: carry out laser lancing on saw blade, by the vibration of joint-cutting saw blade when reducing cutting, thereby reach the cutting effect of low noise; Simple in structure, easy to operate; Reduced the manufacturing energy consumption; Reduced manufacturing cost.
Four, description of drawings
Fig. 1 is the structure chart of saw blade of the present utility model.
1, saw bit matrix 2, sawtooth 3, joint-cutting
Five, the specific embodiment
With reference to accompanying drawing 1, a kind of saw blade, described saw blade are circular, and sawtooth 2 is distributed on the circumference, has joint-cutting 3 on the described saw bit matrix 1.Described joint-cutting evenly distributes on the concentric circles of saw blade circumference.Described joint-cutting is distributed on the same concentrically ringed circumference.Described joint-cutting is S-type.Described joint-cutting is six.
Reduce the vibration of when cutting saw blade during cutting by the joint-cutting on the saw bit matrix, thereby reach the cutting effect of low noise.
Claims (5)
1, a kind of saw blade, described saw blade are circular, and sawtooth is distributed on the circumference, it is characterized in that having joint-cutting on the described saw bit matrix.
2, saw blade as claimed in claim 1 is characterized in that: described joint-cutting evenly distributes on the concentric circles of saw blade circumference.
3, saw blade as claimed in claim 2 is characterized in that: described joint-cutting is distributed on the same concentrically ringed circumference.
4, saw blade as claimed in claim 3 is characterized in that: described joint-cutting is S-type.
5, saw blade as claimed in claim 4 is characterized in that: described joint-cutting is six.
