Description
Technical field
The present invention relates to silent saw blade matrix, be specifically related to a kind of grooving filler silent saw blade matrix.
Background technology
Silent saw blade matrix is a kind of saw bit matrix for reducing sawing noise, such saw bit matrix mainly comprises composite material type saw bit matrix and single-layer metal plate silencing seams type saw bit matrix two kinds, better but to manufacture complicated cost higher, the latter manufactures relatively simple but erasure effect is not enough for the former erasure effect.For silencing seams silent saw blade matrix, in order to improve the performance muffler of this single-layer metal bladed saw sheet matrix, domestic and international correlation technique personage has carried out extensive various research, patent CN92208374 discloses the saw bit matrix of the narrow silencing seams of 0.2 ~ 0.5mm a kind of matrix having been cut a lot of dispersion distribution, but the overall joint-cutting distribution density of the matrix of this saw blade is excessive and have a strong impact on saw blade integral rigidity, and actual use finds that this kind of lamellar body erasure effect is poor and lamellar body rigidity is short for not enough service life; Patent CN200520145567 discloses the saw blade that a kind of matrix is provided with filling gel in silencing seams, but this saw blade joint-cutting area is less and overall filling gel amount is very few, and actual use finds that the general and silica gel of this kind of lamellar body erasure effect easily comes off; Patent CN200820111066 and patent CN200820227664 individually discloses a kind of matrix and is provided with in silencing seams the saw blade of filling bonding agent and damping material, the joint-cutting area of these two kinds of saw blades increases to some extent and overall filling bonding agent and damping material increase to some extent, but this long line " horizontal cutting type " silencing seams will be a greater impact to lamellar body rigidity, actual use find this kind of lamellar body use initial stage erasure effect better but lamellar body to be easily out of shape service life shorter and fill bonding agent and damping material easily comes off.
Summary of the invention
Technical problem to be solved by this invention is: the grooving filler silent saw blade matrix providing a kind of good muffling effect, good rigidly, long service life, brand-new saw bit matrix kerf structure and layout etc. are creatively proposed, solve the problems such as the erasure effect of current single-layer metal plate silencing seams type saw bit matrix not enough or rigidity service life is not enough breakthroughly, significantly improve the comprehensive serviceability of single-layer metal plate silent saw blade matrix.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of grooving filler silent saw blade matrix, comprise how uniform grooving alloy substrate, diameter is D, with nonmetal flexible damping grooving filler, described nonmetal flexible damping grooving filler comprises axial filler, circumference filler and the circular filler of corner, axial filler alignment two lateral process centered by substrate radius, circumference filler alignment two lateral process centered by circumferential oblique line, the angle of substrate radius and circumferential oblique line is 120 ° ~ 145 °, the circular filler of corner is positioned at the intersect ends place of axial filler and circumferential filler, the circle one diameter d1 at the place, non-crossing end of axial filler is 0.20D ~ 0.25D, circle two diameter d 2 at the place, non-crossing end of circumference filler is 0.75D ~ 0.85D, circle three diameter d 3 at the circular filler place of corner is 0.60D ~ 0.65D, the width of axial filler and circumferential filler is 1mm ~ 2.5mm.
Described axial filler and the non-crossing end of circumferential filler are circle.
The circular filler of described axial filler, circumferential filler, corner be one or several in rubber, polyurethane adhesive, silicone adhesive combinationally use and with substrate grooving wall compact siro spinning technology.
Described many groovings alloy substrate excircle is evenly distributed with and adds bendway, and the basic tank degree of depth is all uniformly distributed in adjacent adding between bendway add the bendway degree of depth less than 2/3.
Described to add bendway quantity identical with nonmetal flexible damping grooving filler quantity, and line section and the nonmetal flexible damping grooving filler of deepening bottom of gullet end points and the substrate center of circle are non-intersect.
In preferred version, the angle a of substrate radius and circumferential oblique line is 130 °.
The circular diameter at the place, non-crossing end of axial filler is 0.22D, and the circular diameter d2 at the place, non-crossing end of circumferential filler is 0.79D, and the circular diameter d3 at the circular filler place of corner is 0.62D.
The effect that the present invention can produce is:
Width is adopted to reach the axial filler of 1mm ~ 2.5mm and circumferential filler makes saw blade noise reduction filling member, i.e. a kind of nonmetal flexible damping grooving filler of large volume with corner filler, vibration when effectively can absorb cutting use and noise;
Circumference filler becomes the angle of 120 ° ~ 145 ° with axial filler, this makes circumferential filler tip spacing can not be too small and can not form " crosscut is broken " of matrix, and this layout effectively can ensure rigidity and the service life of matrix;
The non-crossing end of axial filler, the non-crossing end of circumferential filler, the position of corner filler then can ensure lamellar body rigidity, filler area and to the obstruct consumption vibrated during sawing further; Longer axial filler start point distance is close to the center of circle, the circle one diameter d1 at the place, non-crossing end of axial filler is 0.20D ~ 0.25D, and saw blade when using supporting ring flange diameter be generally 30% i.e. about 0.30D of saw bit matrix external diameter, can some be clamped in use between ring flange, such substrate, damping filler, ring flange three contact matrix vibration when forming compound damping structure-can reduce further sawing, thus reduce sawing noise and improve sawing quality;
The both sides raised structures of axial filler and circumferential filler then can effectively increase the contact area of filler and matrix grooving wall on the one hand thus effectively prevent cutting process filler from coming off, and increases the length of grooving and filler and the destruction that reduces matrix rigid on the other hand;
When what matrix excircle was spaced apart add bendway and basic tank then effectively can destroy sawing, the air vibration in sawtooth portion, reduces cutting noise further.Line section and the nonmetal flexible damping grooving filler of deepening bottom of gullet end points and the substrate center of circle are non-intersect---and effectively avoid deepening bottom of gullet and grooving hypotelorism and affect intensity and the rigidity of saw bit matrix.
The present invention creatively proposes brand-new saw bit matrix kerf structure and layout etc., solve the problems such as the erasure effect of current single-layer metal plate silencing seams type saw bit matrix not enough or rigidity service life is not enough breakthroughly, significantly synchronously improve the performances such as the erasure effect of single-layer metal plate silent saw blade matrix, integral rigidity, damping filler slip-off preventing, service life, significantly improve the comprehensive serviceability of single-layer metal plate silent saw blade matrix.
