Description

The toothing of saw blade

Technical field

The utility model is related to the structure and saw-blade structure of blade teeth, more particularly to a kind of toothing of saw blade.

Background technology

Saw blade is the general designation for cutting the thin slice circular knives of solid material.Saw blade can be divided into：Cut for stone material Diamond saw blade；The HSS sawblade (not tungsten carbide button cutter head) cut for metal material；For solid wood, furniture, The hard alloy saw blade of the cuttings such as wood-based plate, aluminium alloy, aluminium section bar, radiator, plastics, plastic-steel.The quality of saw blade depends on saw The quality of piece steel itself or other materials, in order to cut some special substances, in addition it is also necessary to inlay difference on saw blade Cutter head.

But in blades machining and the research process of material, it has been found that the material of saw blade in itself and is not equal to the matter of saw blade Amount, in addition to the steel of high standard, the shape of saw blade, machining accuracy can also influence saw blade quality.

Experiment finds, the vibrations of the quality and saw blade of saw blade in high-speed rotation, and noise has a larger relation, and saw blade The raising of shape and machining accuracy plays the role of very big for reducing vibrations of the saw blade in high-speed rotation, reduction noise.

, it is necessary to which the shape to the sawtooth of saw blade is redesigned for noise reduction damping, reduction is in use Vibrations, especially maintain stabilization of the sawtooth on saw blade axial direction, it is optimal in order to be reached further combined with noise reduction line Noise reduction damping effect.

Thus, it is necessary to design again is carried out to the shape of sawtooth.

Utility model content

The utility model in the prior art, the shape of sawtooth be directed to noise reduction line/silencing groove use carry out it is excellent Change, causing to shake during use the shortcoming of increase, there is provided a kind of toothing of saw blade.The saw blade is reduction and improves saw blade Vibrations and noise project a part, it is therefore an objective to saw blade vibrations and noise can be reduced as much as possible, and can be avoided After noise reduction line/silencing groove is added, caused by the change of saw-blade structure the problem of vibrations increase, reach and maintaining existing saw blade Material and technique it is substantially constant in the case of, improve large saw blade cutting efficiency.

To achieve the above object, the utility model can take following technical proposals：

A kind of toothing of saw blade, it is characterised in that tooth includes tooth root and crown；

Wherein, the side of crown is the tooth base for connecting cutter head, and opposite side is the back of tooth；

A protuberance towards projection on the outside of saw blade is provided with the naked back, the radius of protuberance is less than the length of tooth base Degree.

Further, as a kind of optional scheme, in embodiments herein, a court is provided between adjacent tooth To the recessed circular arc recess in the inner side of saw blade.

Further, as a kind of optional scheme, in embodiments herein, the bottom of the recess of adjacent tooth Offer silencing groove.

Further, as a kind of optional scheme, in embodiments herein, the tooth base is extended always by crown To the junction of recess and tooth base.

Further, as a kind of optional scheme, in embodiments herein, between the protuberance and recess For the straight back of tooth.

Further, as a kind of optional scheme, in embodiments herein, the back of tooth by recess normal Direction extension is obtained.

Further, as a kind of optional scheme, in embodiments herein, the back of tooth by protuberance normal Direction extension is obtained.

Further, as a kind of optional scheme, in embodiments herein, the height of the protuberance is less than tooth The height of sharp end.

Further, as a kind of optional scheme, in embodiments herein, the crown is relative to tooth root direction The direction of the adjacent teeth of tooth base side is tilted.

The utility model has following notable technique effect：

Vibrations and noise progress damping and noise reduction that the different parts of the saw blade with relatively large radius are produced can be directed to.

Further, increase noise reduction line/silencing groove on the saw blade of part and cause saw blade to shake when in use and increased with noise Big the problem of.The effect of noise reduction damping can be admirably achieved by coordinating the use of noise reduction line/silencing groove.

Brief description of the drawings

Fig. 1 is the structural representation of the toothing for the saw blade observed by the axial direction of saw blade.

Embodiment

The utility model is described in further detail with reference to embodiment.

Embodiment 1

As shown in figure 1, for the sake of simple, Fig. 1 only indicates the structure of a tooth, the toothing of other parts is single to repeat A kind of member, toothing of saw blade, tooth 100 includes tooth root 101 and crown 102, and this kind of tooth 100 is adapted to relatively large radius chi Very little saw blade, the saw blade is generally used for the non-metallic materials such as cutting timber.In the application, the shape of tooth 100 refers to by saw blade The shape that axial direction is observed, unless otherwise instructed, the tooth observed by the radial direction of saw blade is straight strip.

Wherein, the side of crown 102 is the tooth base 103 for connecting cutter head, and opposite side is the back of tooth 104；Tooth base 103 is flat Straight straight line, tooth root 101 is extended to by the end of crown 102.

A protuberance 105 towards projection on the outside of saw blade is provided with the back of tooth 104, protuberance 105 is to be approximately towards The direction of the adjacent tooth 100 of the side of the back of tooth 104, and length of the radius less than tooth base 103 of protuberance.

Further, one is provided between adjacent tooth 100 towards the recessed circular arc recess 106 in the inner side of saw blade, Recess is located between adjacent teeth 100, and the circular arc radius of recess 106 is substantially between the height of 1/3~1/4 tooth 100.

Further, the bottom of the recess 106 of adjacent tooth 100 offers silencing groove 200.

Further, the tooth base 103 is extended to the junction of recess 106 and tooth base 103 by crown 102.

Further, it is the straight back of tooth 104 between the protuberance 105 and recess 106.

Further, the back of tooth 104 is obtained by the normal direction extension of recess 106.Further, the back of tooth 104 are obtained by the normal direction extension of protuberance 105.

Further, the height of the protuberance 105 is less than the height of the end of crown 102.The height of protuberance 105 refers to Protuberance end is to the distance at saw blade center, and the height of the end of crown 102 refers to the end of crown 102 to the distance at saw blade center.

Further, the crown 102 relative to tooth root (101) towards the side of the adjacent teeth (100) of tooth base (103) side To inclination.

In a word, preferred embodiment of the present utility model is the foregoing is only, it is all according to present utility model application the scope of the claims institute The equivalent changes and modifications of work, should all belong to the covering scope of the utility model patent.
