Description
Technical field
The present invention relates to the nonmetallic sawing cutlery of a kind of sawing metal and sawing, specifically a kind of inserted tooth type superhard cutting blades
Saw.
Background technique
Currently, the saw of saw industry institute production and marketing both at home and abroad mainly has two big classifications, one kind is saw blade, i.e., is formed on disk periphery
The saw of several sawtooth, wafer saw are positioned with hole, and are mounted on progress sawing work on saw blade lathe.Another kind of is saw blade,
Saw blade divides bands for band and frame saw blade etc. again, and saw blade is not only thin but also length, symmetrical one side of hump are formed with the saw of several sawtooth, this
Kind of saw blade be separately mounted on band-saw machine tool or buck saw lathe on carry out sawing work.With the appearance of superhard material, PCD Buddha's warrior attendant
Stone composite blade and cubic boron nitride composite blade (PCBN) superhard material blade, are widely answered on saw blade
With.But superhard cutting blade saw blade both domestic and external is welded structure so far, inserted tooth type superhard cutting blade saw blade still end occurs,
Superhard cutting blade saw blade production and marketing industry still belongs to blank.Intellectual Property Right Bureau of the RPC was on 06 09th, 2010, Granted publication
Utility model title: ultra-hard material saw blade, this be it is a kind of superhard material blade is welded on saw blade matrix after reprocessing
Molding ultra-hard material saw blade.
Summary of the invention
A kind of inserted tooth type superhard cutting blade saw is provided it is an object of the invention to overcome the above-mentioned insufficient of the prior art, it is convenient
Replacement, it can be obviously prolonged saw cutting life.
The technical scheme is that including matrix and blade；It is arranged with sawtooth on matrix, has saw on each sawtooth
Serrated knife film trap；Blade is inlaid in sawtooth insert groove, blade cutting edge exposes and is higher than matrix sawtooth tooth height.
The blade is PCD diamond composite blade or cubic boron nitride composite blade.
The blade being embedded in sawtooth insert groove, assemble relief angle blade angle: left tool cutting edge angle KrL is 90 ° ± 2 °, preceding
Angle γ.It is 0 ° -20 °, primary clearance ɑ05 ° -20 °, 0 ° -5 ° of left secondary drift angle KrL ', 0 ° -5 ° of right auxiliary angle KrR ', left secondary relief angle
ɑ00 ° -5 ° of L ', right front clearance ɑ0R´0°—5°。
The blade of the blade is symmetrically the toothing to match with the tooth-shape structure on matrix on one side.
The blade of the blade is consistent with sawtooth land direction on matrix.
Described matrix is circular saw blade substrate, bands for band matrix or frame saw blade matrix.
The beneficial effects of the present invention are: the influence due to blade without high-temperature soldering easily guarantees blade quality, advantageous bright
It is aobvious to extend saw cutting life.It is convenient for changing, if individual sawtooth are badly damaged, as long as after being pulled out, then be bumped into a new blade, i.e.,
It can continuous work.

Specific embodiment
As shown in Figure 1, saw blade is made of matrix 1 and blade 2.It is arranged with sawtooth on matrix 1, is had on each sawtooth
Sawtooth insert groove；Blade 2 is inlaid in sawtooth insert groove, blade cutting edge exposes and is higher than matrix sawtooth tooth height.Blade 2 is PCD
Diamond composite blade or cubic boron nitride composite blade.
As shown in Fig. 2, being frame saw blade.The hump 3 of the matrix 1 of frame saw blade symmetrically to be formed with several on one side orderly aligned
Sawtooth is arranged with sawtooth on the matrix 1 of frame saw blade, there is sawtooth insert groove on each sawtooth；Knife is inlaid in sawtooth insert groove
Piece 2, blade cutting edge expose and are higher than matrix sawtooth tooth height.Blade 2 is PCD diamond composite blade or cubic boron nitride composite cutter
Piece.
As shown in figure 3, being bands for band.The hump 3 of bands for band matrix 1 is symmetrically formed with several orderly aligned saws on one side
Tooth.It is arranged with sawtooth on the matrix 1 of bands for band, there is sawtooth insert groove on each sawtooth；Blade is inlaid in sawtooth insert groove
2, blade cutting edge exposes and is higher than matrix sawtooth tooth height.Blade 2 is PCD diamond composite blade or cubic boron nitride composite cutter
Piece.
As shown in figure 4, sawtooth orderly aligned on matrix 1, S is tooth pitch, and H1 is that base tooth is high, and H2 is that preceding table top tooth is high,
γ.It is saw blade anterior angle, L is the groove width of cutting insert piece on matrix.B is the thickness of matrix, and 4 be preceding table top, and 5 be rear table top, and 6 be tooth
Back, 7 be chip pocket.
As shown in Figure 5,6, blade diamond level, B are the width of blade, and KrL is the left tool cutting edge angle of sawtooth, and KrL ' is
Left secondary the drift angle KrL ', KrR ' of sawtooth are the right auxiliary angles of sawtooth.H is blade overall thickness, has the recessed of symmetry requirement to blade
Groove width B1, the thickness h 1 of blade groove bottom surface to top surface.ɑ0L ' is the left secondary relief angle of blade, ɑ0R ' is the right front clearance of blade.
Guarantee there are enough gaps when sawing between matrix two sides and sawn timber, the width B of blade will be significantly greater than the thickness of saw blade matrix
Spend b.Left secondary drift angle KrL ', right auxiliary angle KrR ', left secondary relief angle ɑ0L ', right front clearance ɑ0R ' is 0 ° -5 °.
As shown in fig. 7, H is the total length of blade, ɑ0It is the primary clearance of blade.
As shown in figure 8, blade 2 is embedded in 1 insert groove of matrix.S is tooth pitch, and blade 2 is inserted into slot bottom, pre-designed
2 length H of blade can just make blade cutting edge expose the high certain altitude of base tooth.Saw blade anterior angle γ.It is 0 ° -20 °, blade 2
Primary clearance ɑ0It is 5 ° -20 °.At this point, the rear table top and preceding table top of matrix, this blade are close in the groove floor of blade and top surface
Matrix is inlayed, the intersection mosaic technology of matrix cutting insert piece not only can guarantee the assembly precision of blade, and can make the clamping of blade more
Add stable and firm.
