Description
Technical field
This utility model relates to a kind of ripple saw blade, and specifically one combination ripple sintered saw bits, belongs to pottery, stone
The cutting field of the Inorganic Non-metallic Materials such as material, concrete.
Background technology
At present, it is common to use diamond saw blade be divided into flat pattern and ripple type.So-called flat pattern saw blade refers to that cutter head is relative
Two side generally planar structures, ripple type refers to that two sides that cutter head is relative are dispersed with the groove of a fixed structure.Flat pattern
There is friction with the cutting surfaces of cutting object in relative two side of saw blade in cutting process, adds squeezing of chip
Pressure effect, produces amount of heat and reaches saw bit matrix, and saw bit matrix produces thermal stress and is susceptible to deformation, causes cutting work
Impact.The groove of ripple type saw blade has certain appearance bits effect, chip is thrown away, decrease after groove produces cutting object
Two sides of cutter head and the friction of cutting object, make Cutting Drag diminish.Owing to saw blade two sides groove is at saw blade high speed rotating
During be easier to heat radiation, the thermal stress deformation of saw blade can be effectively mitigated or eliminated.The corner angle of saw blade two sides ripple groove are to
Cutting surfaces has certain scraping action, and the surface of the work after processing is more smooth, reduces between saw blade and workpiece simultaneously
Frictional resistance, the sharpness of saw blade improves.
In currently used ripple saw blade, ripple struction is distributed along radial direction (or approximately along radial direction), along circle
Circumferential direction periodic arrangement.Such ripple there is problems in that one is that ripple struction is identical, and frequency is high in a circumferential direction.
Owing to the structure of ripple is identical, the vibration produced in cutting process is identical, and the concordance of frequency of vibration is higher；Owing to ripple is tied
Structure frequency in a circumferential direction is the highest, arises that dither, under certain condition, occurs that the probability of resonance raises.Two
Be ripple struction be simple, single, cutter head is overall from the internal diameter of cutter head to external diameter, and structure is identical,
Circumferencial direction is uniform, makes saw blade heat radiation in rotary course be greatly affected.Three is that the tow sides of common oblique ripple have
Bigger performance difference, during use, installation direction is single, it is impossible to anti-loaded.Four is owing to ripple struction is simple, kind is single,
The direction of each ripple is identical with the angle that the cylindrical tangential direction of saw blade external diameter point of intersection is formed with ripple, and repeatability is higher,
Reduce the effect of ripple.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of can to improve cutting stationarity, heat-sinking capability good
Sintering class saw blade.
For solving above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of combination ripple sintered saw bits, including circular saw blade matrix be sintered in the outer peripheral diamond knife of saw bit matrix
Head, two sides that described diamond segment is relative arrange external groove and the inner groovy of along the circumferential direction distribution period arrangement,
Described external groove is surrounded bowl-type by three rectilinear grooves and opening direction points to diamond segment outward flange, described indent
Groove is surrounded bowl-type by three rectilinear grooves and opening direction points to diamond segment inward flange；At saw bit matrix radially
Corresponding external groove is set and inner groovy is one group.
Further, the bowl-type external groove and the bowl-type inner groovy centre position that are oppositely arranged are arranged along saw bit matrix radial direction side
To the straight-line groove from diamond segment outward flange to inward flange.
Further, adjacent two groups arrange four linear grooves and surround quadrilaterai socket between external groove and inner groovy
Groove.
Further, the external groove of described diamond segment two sides was interlocked for 1/2 cycle, diamond segment two sides interior
Groove interlocked for 1/2 cycle.
Further, the degree of depth of groove is the 1/25～1/3 of diamond segment thickness.
Owing to using technique scheme, have the beneficial effects that produced by this utility model:
Ripple struction of the present utility model each cycle is at most provided with 4 different ripples, makes saw blade ensure cutting cutting edge of a knife or a sword
Reduce the frequency of identical vibration on the premise of profit degree, decrease the probability producing resonance, be effectively improved the flat of cutting
Stability, feel is more comfortable, and cut quality is improved.
Ripple struction of the present utility model defines a plurality of gas channel, and adds area of dissipation, makes radiating effect
It is improved, reduces the deformation owing to cutting the saw bit matrix that the thermal stress produced causes.
Ripple struction of the present utility model is symmetrical structure, is not required to distinguish installation direction, with the most single oblique ripple knot
Structure is compared, easier for installation.
The straight-line groove of this utility model entirety is the overall structure from cutter head internal diameter to head outer diameter, radially arranged,
Article three, short lines groove surrounds bowl-type ripple struction, the dual-side of bowl-type ripple struction just becoming with overall straight-line groove respectively,
Negative angle, eliminates the repeatability of single structure ripple effect, makes the sharpness of saw blade obtain bigger raising.
Quadrilateral structure ripple improves the cutter head concordance in whole lifetime internal cutting performance.
