Technical field
The utility model relates to inorganic non-metallic material cutting technique field, especially a kind of ripple diamond saw blade.
Background technique
The cutter head ripple of diamond saw blade is to be dispersed with the groove of certain structure in two opposite sides of diamond segment,
Existing ripple saw blade is convenient for good appearance and design, adjacent the distance between two cutter head ripples on diamond segment
It is equal.Saw blade can generate high-frequency vibration under up to ten thousand turns of revolving speed per minute, and identical ripple can cause the height of identical frequency
Frequency vibration, the frequency of high-frequency vibration and the intrinsic frequency of cutting equipment when integral multiple at can cause to resonate, the two frequencies
The resonance effect that identical or at integral multiple when generates becomes apparent from, and resonance can generate apparent large-amplitude vibration and impact, make to cut
It cannot proceed normally.
When saw blade rotation, the one end first contacted with cutting object on each diamond segment excircle is known as originating
End, by starting point and the plane vertical with saw blade end surface is known as front end face；On diamond segment excircle finally with cutting pair
As the other end of contact is known as end, by end and the plane vertical with saw blade end surface is known as rear end face.Cooling chip removal
Angle between the front end face and rear end face of slot two sides and the plane for passing through cooling chip space symmetry axis be defined as nose angle and
Rear end angle.Under normal conditions, in addition to the tiltedly saw blade of cooling chip space, the nose angle of saw blade is also equal with rear end angle.

Rear end angle, the nose angle is between 12 °~35 °, and the angle at the rear end angle is positive value or negative value, and the angle at rear end angle is with before
The sum of the angle at angle is held to be greater than zero degree, two sides are provided with cutter head ripple, diamond segment side on diamond segment thickness direction
The distance between adjacent two cutter head ripple it is unequal.
Technical solutions of the utility model further improvement lies in that: by the starting point of diamond segment to the adjacent of end
The distance between two cutter head ripples gradually reduce.
Technical solutions of the utility model further improvement lies in that: by the starting point of diamond segment to the adjacent of end
The distance between two cutter head ripples are gradually reduced according to the relationship for the arithmetic progression that successively decreases.
Technical solutions of the utility model further improvement lies in that: the maximum distance between two neighboring cutter head ripple is greater than
Twice of diamond segment thickness, the minimum range between two neighboring cutter head ripple are greater than the thickness of diamond segment.
Technical solutions of the utility model further improvement lies in that: the cutter head ripple of diamond segment thickness direction two sides
Position mutually staggers.
Technical solutions of the utility model further improvement lies in that: between cutter head ripple and saw blade radial direction be in 15 ° of angles, knife
The inclined direction of bow wave line is opposite with saw blade direction of rotation.
By adopting the above-described technical solution, the technological progress that the utility model obtains is:
The damage for slowing down diamond segment start-up portion improves the stress of diamond segment, extends diamond
The service life of saw blade reduces chipping and the disrepair phenomenon of cutting object, reduces the covibration of diamond saw blade, so that cutting
It is more steady to cut process.
Nose angle guarantees the stress that diamond segment is improved while possessing enough cutting force between 12 °~35 °
State reduces the resistance being subject in rotation, reduces the damage of diamond segment, cut convenient for diamond segment.
The angle at rear end angle is matched with the angle of nose angle, and nose angle and the overall angle at rear end angle is made to be greater than a fixed number
Value, convenient for clast is discharged from cooling chip space.
The distance between two neighboring cutter head ripple gradually reduces so that saw blade produces a variety of vibration weeks in cutting
Phase reduces a possibility that generation is resonated, improves stability when cutting.The distance between two neighboring cutter head ripple according to
Successively decrease arithmetic progression relationship gradually reduce so that designer by simple mode meet cutter head corrugation density be incremented by set
Meter requires, and facilitates to diamond designing and manufacturing to the end.
Cutter head ripple improves the sharpness of diamond saw blade, the cutter head ripple of diamond segment thickness direction two sides
Position, which mutually staggers, to be avoided diamond segment thickness and reduces at cutter head ripple excessively, and the intensity of diamond segment is improved,
Improve the consistency of cutting.It is in 10 °~20 ° of angle, the inclined direction of cutter head ripple between cutter head ripple and saw blade radial direction
With saw blade direction of rotation on the contrary, these improve the stress at cutter head ripple, reduce the phenomenon of cutter head ripple breakage.
