Abstract
The utility model discloses a laser-cutting diamond muffler circular saw blade which consists of a circular base body (1) and a diamond cutter head (2); the circular base body (1) is provided with a central hole and also provided with 4 to 16 auricle-shaped first muffler seam (4) distributed symmetrically along the center; the seam width L1 of the muffler seam (4) is equal to or less than 0.22 mm, while the seam depth of the muffler seam h1 is more than or equal to the product of the thickness of the base body multiplied by 90 percent; for further improving the muffler effect, a start-like shaped second muffler seam (6) can be arranged in a radial direction at the position of each groove mouth near the diamond cutter head (2) on the base body (1); the muffler saw blade has simple processing art and remarkable muffler effect, and also keeps the original intensity; in addition, through adopting high-power laser welding technology, the utility model ensures the combination intensity between the cutter head and the base body and improves the operational safety.
Description
Technical field
The utility model relates to a kind of saw blade, specifically, is a kind of diamond silencing circular saw disc that utilizes laser technology to make.
Background technology
Silent saw blade is as a kind of new product of environment protect, and its imagination starts from the mid-90, is proposed and has been carried out a large amount of experimental studies by more American-European countries.Mechanism according to noise produces has proposed a kind of measure of eliminating the saw blade noise in the world, promptly adopts " sandwich " technology, and additional composite between the matrix of two sides prevents saw blade resonance.Some external famous diamond tool manufactories have all utilized laser cutting technique to develop the noise reduction diamond disc of this " sandwich " formula as German Momohof company, SDC company of Korea S, Britain Nimbus company.Such Product Safety height, the long service life of external exploitation, cutting noise can reduce by tens decibels.But, this " sandwich " silent saw blade complex manufacturing technology, the production cycle is long, the development cost height.
At present, the somebody develops another kind of silent saw blade, thus promptly on steel substrate a kind of special graph of accurate cutting to prevent that producing resonance in the saw blade cutting process reaches the purpose that reduces and even eliminate noise.But existing this saw blade is to be the erasure effect that cost realizes to sacrifice saw bit matrix intensity, has reduced the serviceability of saw blade, also is difficult to guarantee handling safety.
Summary of the invention
The purpose of this utility model provides a kind ofly can reduce noise, its matrix strength remains unchanged substantially and the simple new pattern laser joint-cutting of manufacture craft diamond silencing circular saw disc.
For realizing above-mentioned utility model purpose, laser lancing diamond silencing circular saw disc, form by circular base and diamond segment, central authorities at circular base have centre bore, it is characterized in that: circular base is provided with first noise reduction seam of 4-16 bar similar " auricle " shape that is symmetrically distributed along the center, width L≤0.2mm, degree of depth h 〉=matrix thickness * 90% in the slit of first noise reduction seam.
As improvement of the present utility model, can on matrix, radially be provided with similar in the notch place near cutter head
Second noise reduction seam of shape.
Laser lancing diamond silencing circular saw disc of the present utility model, it is the noise reduction seam of cutting 4-16 bar similar " auricle " shape on matrix, to cut off or to weaken the propagation of sound wave in matrix, the audio frequency resonance that makes it and be cut on the material contact site reduces, thereby reach the purpose that abates the noise, and since joint-cutting thin (≤0.2mm), to the not influence of intensity of matrix.Show that through test laser lancing diamond silencing circular saw disc can be reduced to 40dB from 120dB with noise, erasure effect is very remarkable.In addition, compare with the manufacture craft of " sandwich " silent saw blade, the utility model technology is only to utilize laser beam precision on matrix to cut out some noise reduction seams, and manufacture craft is simple.
On matrix, increase by second noise reduction seam and can further improve erasure effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of silencing circular saw disc of the present utility model.
The specific embodiment
Because the utility model laser lancing diamond silencing circular saw disc be the symmetrical structure of circle, so a figure has gone out half of its front schematic view among Fig. 1.In the present embodiment, saw blade is made of matrix 1 and diamond segment 2, and its diameter is 400mm.The material of matrix 1 is 50Mn2V, its thickness is 2.8mm, and its central authorities have centre bore 3, utilizes laser beam 12 first noise reduction seams 4 along centre bore symmetry, similar " auricle " shape of accurate cutting on matrix 1, Fig. 1 only demonstrates 6, the gap width L of first noise reduction seam 4
1Be 0.18mm, degree of depth h
1Be 95% of matrix thickness, its length is about 1/3rd of matrix radius.This saw blade can make noise be reduced to about 40dB.For ease of processing, also be provided with processing locating hole 5 on the matrix 1.
The bar number of first noise reduction seam 4 can be the 4-16 bar, the width L in its slit
1≤ 0.2mm, degree of depth h
1〉=matrix thickness * 90% all can.The length of first noise reduction seam 4 is about that three of matrix radius/for the moment, the combination property of saw blade is better.And the utility model saw blade is to adopt the high power laser light solder technology with diamond segment and matrix bond together, guarantees its bond strength, has also increased substantially processing safety.
For further improving erasure effect, can on matrix, radially be provided with similar in the notch place near diamond segment
Second noise reduction seam (6) of shape.For realizing better erasure effect and keep the original intensity of matrix, the number of second noise reduction seam is equal with the notch number, the width of the length in slit and notch is all goodly mutually, but is not limited thereto.The width L in its slit
2≤ 0.2mm, degree of depth h
2〉=matrix thickness * 90% all can.
Claims (2)
1. laser lancing diamond silencing circular saw disc, form by circular base (1) and diamond segment (2), central authorities at circular base (1) have centre bore (3), it is characterized in that: circular base (1) is provided with first noise reduction seam (4) of 4-16 bar similar " auricle " shape that is symmetrically distributed along the center, the width L in the slit of noise reduction seam (4)
1≤ 0.2mm, degree of depth h
1〉=matrix thickness * 90%.
2. a laser lancing diamond silencing circular saw disc as claimed in claim 1 is characterized in that: upward radially be provided with similar near the notch place of diamond segment (2) at described matrix (1)
Second noise reduction seam (6) of shape.
