Abstract
The utility model relates to a hard alloy circular saw blade with unequal teeth-distance, low-noise and damping, has teeth in the outer ring and a hole in the center. The position near the center hole is provided with a 'J'-shaped damping silencing groove. An inclined thermal expansion groove whose inner end is connected with a curve-shaped damping silencing groove is arranged in an outer tooth ring. The utility model has the advantages of simple structure, easy manufacturing, good silencing effect, prevention of environmental pollution and high stability.
Description
The utility model relates to a kind of metal machining tool, especially a kind of sheet of crouching.
Low noise, subtract behaviour's sintered carbide circular saw, having occurred manufacturers such as multiple pattern Germany, Japan, Italy, Taiwan on market all has this product to come out, and mainly is to add damping from the vibration silencer groove to set about, and also has the extraordinary quieter material of research to do saw blade.Though these structures have very big vibration silencer function, its processing technology complexity, the technological requirement height is difficult for reaching.
The purpose of this utility model provides a kind of simple in structure, handling ease, noise reduction, good damping result, can prevent the pollution of the environment, good stability do not wait tooth pitch low noise vibration damping sintered carbide circular saw.
The purpose of this utility model is achieved in that
There is tooth the utility model outer ring, and the center is porose, it is characterized in that: near central hole, " J " shape vibration damping noise reduction groove is arranged, have oblique line shape heat expansion groove at external toothing, its inner end links to each other with shaped form vibration damping noise reduction groove.
The two ends of each vibration damping noise reduction groove are porose.
The vibration damping noise reduction groove curve shape that links to each other with oblique line shape heat expansion groove is corrugated.
Near the vibration damping noise reduction groove at the vibration damping noise reduction groove of central hole and external toothing place each to count sum be odd number.
Tooth pitch between each adjacent teeth does not wait.
The utility model is owing to adopt said structure to have above characteristics:
1, blade material YG8, the modified back of saw blade 65Mn hardness is greater than HRc45.
2, do not wait tooth pitch, the vibration wave phase shifting that per tooth disturbance air is produced has the effect of cancelling each other.
3, vibration silencer groove, that can cut off saw blade circumferentially involves the warp-wise wave propagation, can weaken the vibration of saw blade.
4, the heat expansion groove of external toothing and vibration silencer groove fuse, and manufacturing process is simple.
5, shaped grooved except the effect of vibration and noise reducing, improve internal stress in addition and distribute and to have the suitable effect that expands.
6, higher steady precision is arranged, jump in the footpath, end is jumped less than 0.05mm, steady precision height, and effect of vibration and noise reduction is better.
7, saw blade has enough rigidity, and working speed is 3000～4500 commentaries on classics.
8, the noise reduction grooved tooth pitch sintered carbide circular saw such as can be used for as 40,56,80 teeth or 30,60,90 teeth.
9, flute profile and geometric angle are selected according to cutting material, can adopt left and right sides helical teeth X
2X
Y, the flat right tooth X in a left side
2PX
y, flat terraced tooth PT.Anterior angle γ=10 °～20 °, relief angle 2=10 °～15 °, oblique angle ε
=5 °～10 °, ε
2=0 °～5 °, interior re-entrant angle λ=1.5 °～2 °.
Advantage of the present utility model:
1, the idle running noise is than the low 10dB(A of general hardness alloy saw blade of the same type) about.
2, sawing quality is better than general sintered carbide circular saw of the same type, as surface roughness and perpendicularity height.
3, the accuracy of manufacture is than general sintered carbide circular saw height of the same type, and it is complicated that technology is wanted, and cost is high.
4, use sawing machine precision height, noise reduction is better.
5, the life-span long, good stability.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the utility model structure chart.
Among the figure: the cylindrical of saw blade 1 has tooth, and its adjacent teeth is not apart from waiting, and there is centre bore 2 centre, near central hole three " J " shape vibration damping noise reduction grooves 3 is arranged, and respectively there is a hole 31,32 at the two ends of each vibration damping noise reduction groove, prevents that stress is concentrated.External toothing is an oblique line shape heat expansion groove 5, and its inner end links to each other with shaped form vibration damping noise reduction groove, and the width of oblique line shape heat expansion groove 5 is greater than shaped form vibration damping noise reduction groove 4, and shaped form vibration damping noise reduction groove 4 is corrugated, and respectively there is a hole 41,42 at its two ends.(in like manner prevent to should be concentrated, increase vibration damping erasure effect).Totally four of oblique line shape heat expansion groove 5 and shaped form vibration damping noise reduction grooves.
Claims (6)
