Description

A kind of noise reduction diamond saw blade

Technical field

The utility model relates in particular to a kind of noise reduction diamond saw blades.

Background technique

When saw blade rotates, each tooth tip generates monopole radiation stream, and is discharged periodically by the saw kerf of workbench, by Fierce variation occurs in stream pressure, generates exhaust noise therewith, the power per liter of exhaust noise increases also with saw blade linear velocity And sharply increase, when saw blade high speed rotation, whenever be vortexed isolated frequency it is close with the intrinsic frequency of saw blade when, just occur to be total to Vibration just issues " shriek ", and this " shriek " noise can be to the health of damage people.

Summary of the invention

The purpose of this utility model is to make improvement and innovation for shortcoming and defect present in background technique, provides one Kind noise reduction diamond saw blade, the noise reduction diamond saw blade are avoided that diamond saw blade resonates, and saw blade sending is avoided " to scream Sound " ensures the health of operator.

To achieve the above object, the technical solution of the utility model is: a kind of noise reduction diamond saw blade, including circular base Body and it is welded on matrix outer circle upper cutter head, blind hole is offered in described matrix, the blind hole and matrix outer circle are concentric, and in blind hole In be provided with circular compoboard, the composite plate weld is also connected with rubber between the compoboard and matrix on matrix Ring.

The radius of the blind hole is the 1/2 ~ 3/4 of matrix radius in one of the embodiments, and the depth of the blind hole is The 1/2 of matrix thickness.Blind hole is set, to be arranged compoboard and rubber ring in blind hole, guarantees compoboard, rubber ring, base The planarization on the surface of body.

The compoboard is the round plate of brass material in one of the embodiments, and the radius of the compoboard is The 2/3 ~ 3/4 of blind hole radius, the depth with a thickness of blind hole of the compoboard.The composite plate weld of brass material on matrix, And it is concentric with blind hole, and the material of matrix is 65Mn spring steel, when saw blade high-speed rotation, it is vortexed the frequency of separation and consolidating for matrix There is frequency identical, matrix resonates, and when matrix vibration is transmitted to compoboard, since matrix and compoboard are two kinds of differences Metal material, the intrinsic frequency of the two is not identical, so vibration is difficult to make matrix to generate resonance, and then reduces the vibration of matrix It is dynamic, reduce noise.

The thickness of the rubber ring is identical as compoboard in one of the embodiments,.It is set between matrix and compoboard Rubber ring is set, since the damped coefficient of rubber is larger, the vibration of matrix is absorbed, realizes vibration damping, reduce noise.

Perforative bloop is offered on described matrix and compoboard in one of the embodiments, which surround The matrix center of circle is equidistantly at least arranged four.Bloop is opened up on matrix and compoboard, can effectively block matrix and compoboard On vibration, and then realize vibration damping, reduce noise.

The advantages of the utility model and the utility model has the advantages that

The utility model use combined type matrix, by the composite plate weld of brass material 65Mn spring steel material matrix On, and rubber ring is set between compoboard and matrix, and saw bit matrix made of the combination of materials by two kinds of unlike materials, energy It effectively avoids saw bit matrix resonance from issuing " shriek ", and the feature big using rubber damping coefficient, absorbs the vibration of matrix, benefit The vibration of matrix and compoboard is blocked with bloop, realizes vibration damping, is reduced noise, is ensured the health of operator.

Specific embodiment

The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model, It states.The utility model preferred embodiments out have been given in attached drawing.But the utility model can be realized in many different forms, It is not limited to the examples described herein.Opposite, purpose of providing these embodiments is makes in the disclosure of the utility model Hold more thorough and comprehensive.

It should be noted that when element be considered as " setting " or " connection " on the other element, it can be directly Setting connects on the other element or may be simultaneously present centering elements.

Unless otherwise defined, all technical and scientific terms used herein and the technical field of the utility model The normally understood meaning of technical staff is identical.Term used in the description is intended merely to describe specifically to implement purpose, no It is intended to be limited to the utility model.

In fig. 1-3: matrix 1, cutter head 2, rubber ring 4, bloop 5, axis hole 6, compoboard 7, blind hole 8.

As shown in Figure 1-3, the material of matrix 1 is 65Mn spring steel, it is welded with cutter head 2 along circular 1 outer circle of matrix, in base Blind hole 8 is offered on body 1, the radius of blind hole 8 is the 1/2 ~ 3/4 of 1 radius of matrix, and the radius of blind hole 8 is matrix 1 in the present embodiment The 3/4 of radius.The depth of blind hole 8 is the 1/2 of 1 thickness of matrix, and compoboard 7 is welded on matrix 1, and compoboard 7 is brass material The round plate of matter, and the radius of compoboard 7 is the 2/3 ~ 3/4 of 8 radius of blind hole, the radius of compoboard 7 is blind in the present embodiment The 3/4 of 8 radius of hole.The thickness of compoboard 7 and the deep equality of blind hole 8.Rubber is also connected between matrix 1 and compoboard 7 The thickness of ring 4, rubber ring 4 is identical as the thickness of compoboard 7.Perforative bloop 5 is offered on matrix 1 and compoboard 7, it should Bloop 5 is equidistantly at least arranged four around 1 center of circle of matrix, and six bloops 5 are arranged in the present embodiment.

The working principle of the utility model is: compoboard 7 is welded in the blind hole 8 of matrix 1, then rubber ring 4 is clamped Between matrix 1 and compoboard 7.When diamond saw blade high-speed rotation, since saw bit matrix is made of unlike material , the intrinsic frequency of various materials is different, and the frequency for being vortexed separation is difficult to that saw blade is made to generate resonance, and saw blade is avoided to issue " shriek ", and then realize noise reduction, ensure the health of operator.

Embodiment described in the utility model is only the description carried out to preferred embodiments of the present invention, not The conception and scope of the utility model is defined, under the premise of not departing from the design concept of the utility model in this field The various changes and improvements that engineers and technicians make the technical solution of the utility model each fall within the protection of the utility model Range, technical content requested for protection of the utility model are all described in the claims.
