Description
Technical field
The present invention relates to a kind of saw bit matrix, be specifically related to a kind of riveted joint auxiliary type viscose glue compound silencing saw blade matrix.
Background technology
The reduction of sawing noise is the research emphasis in cutting field all the time, the physical and mental health of sawing noise not only have impact on cutting operation person, and great destruction is caused to the environment of surrounding, thus have impact on the expansion of sawing application and the raising of cutting operating efficiency.In order to reduce sawing noise, it is the type media such as clamping copper sheet three to be fixed together by spot welding and to form spot welding sandwich compound silencing saw blade matrix in the middle of double layer of metal plate more widely that saw bit matrix optimization aspect uses at present, in addition Chinese patent CN201316846Y discloses a kind of completely with the compound silencing saw blade noise reduction having intermediate medium sheet of rivet link, CN101518838A discloses a kind of compound silencing saw blade matrix having middle dielectric layer of laser weld, the compound silencing saw blade matrix of above-mentioned three types can reduce sawing noise to a certain extent, but there are complex procedures and the high distinct disadvantage of cost of manufacture.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of riveted joint auxiliary type viscose glue compound silencing saw blade matrix, under the prerequisite improving composite saw blade matrix working (machining) efficiency and reduction composite saw blade matrix processing cost, can reduce the noise produced in sawing further.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of riveted joint auxiliary type viscose glue compound silencing saw blade matrix, portion is provided with spindle mounting hole in the base, cylindrical is provided with sawtooth, and the mode that described matrix is combined by bonding and riveted joint by upper metallic plate and lower metallic plate links together.
The upper metallic plate of described saw bit matrix and the bonding region of lower metallic plate be bottom sawtooth between central principal axis installing hole, form a bonding glue-line.
On described saw blade, metallic plate and lower metallic plate are provided with pit or groove at the inner surface of bonding region.
Described groove is the buckling curve grooves such as straight trough, circumferential groove or Wave curved groove.
The pit of described saw blade or depth of groove are less than 2/5ths of metallic plate or lower plate thickness, and the diameter of pit and the width of groove are no more than the twice of metallic plate or lower metallic plate plate thickness.
Adopt rivet when upper metallic plate and the riveted joint of lower metallic plate, rivet installation site is that around sawtooth position and central principal axis installing hole, sawtooth position is teeth portion rivet, and the rivet around central principal axis installing hole is middle hole rivet.
Described teeth portion rivet and middle hole rivet be evenly distributed on separately one with saw bit matrix central point for the center of circle circumferentially, and each sawtooth has a teeth portion rivet at least.
After described teeth portion rivet and middle hole rivet are installed, its both ends of the surface are all lower than saw bit matrix face.
Be provided with tunneling hole bottom described saw bit matrix sawtooth, and tunneling hole be evenly distributed on one with saw bit matrix central point for the center of circle circumferentially.
Described tunneling hole is smooth drops hole or circular hole.
One riveted joint auxiliary type viscose glue compound silencing saw blade matrix provided by the invention, link together by adopting the bonding mode combined with riveted joint of double layer of metal plate, two metallic plates do not need to heat-treat after combining, and rivet to be only evenly distributed on around sawtooth portion and centre bore two circumferentially, thus it is more simple and easy that this composite saw blade matrix is processed; Because actual bond area is comparatively large, and rivet around cylindrical teeth portion and endoporus, thus make lamellar body have good strength and stiffness; And because the pliable and tough bonding glue-line between metallic plate is for vibration and the absorption of noise, the groove of metallic plate inner face is to the obstruct of noise, rivet is to vibration and the self-absorption of noise, bottom matrix sawtooth, tunneling hole is to the acting in conjunction of the factors such as the obstruct of noise, thus achieves the more excellent cutting anti-acoustic capability of this composite saw blade matrix.
The effect that the present invention can produce is: under the processed complex degree reducing compound silencing saw blade matrix and the prerequisite ensureing lamellar body intensity and toughness, effectively reduce its sawing vibration and noise, improve its cutting cooling performance, improve cutting stationarity and cut quality.
