Description
Technical field
This utility model relates to a kind of ripple saw blade, a kind of big chip pocket ripple sintered saw bits, belong to pottery,
The cutting field of the Inorganic Non-metallic Materials such as stone material, concrete.
Background technology
At present, it is common to use diamond saw blade be divided into flat pattern and ripple type.Two sides that flat pattern saw blade is relative are being cut
During cutting with cutting object cutting surfaces contact area greatly, friction is also big, adds the squeezing action of chip, can produce a large amount of
Frictional heat reaches saw bit matrix, and saw bit matrix easily deforms under thermal stress effect, and cutting causes having a strong impact on.Ripple type
Saw blade arranges groove in two relative sides, groove have appearance bits, chip removal effect, can reduce two sides of diamond segment with
The friction of cutting object, thus reduce Cutting Drag.Diamond segment two sides corrugation grooves is in saw blade high-speed rotation
Being prone to heat radiation, the groove corner angle of saw blade two sides ripple also have certain scraping action to cutting surfaces.So, after processing
Surface of the work more smooth, the sharpness of saw blade is improved simultaneously.
In currently used ripple saw blade, ripple struction is generally along radial direction or is distributed approximately along radial direction,
Corrugation grooves is from the internal diameter of diamond segment to external diameter, along the through whole diamond segment of radial direction, and week in a circumferential direction
Phase property arranges.Such ripple there is problems in that
Due to the existence of groove, the position tool tip material lower thickness that diamond segment is bonding with saw bit matrix, part saw
Sheet is the thinnest greatly destroys the intensity of diamond segment to less than 0.1 millimeter, and diamond segment is easy to occur that tooth is existing
As, reduce quality and the service life of saw blade.
Why this problem occurs, is owing to corrugation grooves is from the internal extension of outer radial cutter head, until cutter head internal diameter,
This is too much in order to solve chip, when exceeding the appearance bits ability of corrugation grooves, makes chip flow to cutter head internal diameter with inner region, prevents
" plug cutter " phenomenon there is and the measure taked.But this measure makes again cutter head intensity reduce simultaneously.In order to solve the problems referred to above, portion
Dividing product to use the method thickening cutter head, this brings again the problem reducing sharpness.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of before guarantee fund's diamond tool bit sharpness and intensity
Put, there is the good sintering class saw blade holding bits ability.
For solving above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of big chip pocket ripple sintered saw bits, including circular saw blade matrix and the diamond being sintered in saw bit matrix edge
Cutter head, described diamond segment two sides arrange two groups of crescent shaped groove being distributed uniformly and circumferentially, bigger crescent moon
Connected in star one is located close to diamond segment inward flange side, and less crescent shaped groove two is located close to outside diamond segment
Edge side；The line of symmetry of crescent shaped groove one and the line of symmetry of crescent shaped groove two are point-blank.
Further, arrange in the line of symmetry position of crescent shaped groove one and crescent shaped groove two from crescent shaped groove one

Further, the crescent moon opening direction of described crescent shaped groove one and crescent shaped groove two is all towards diamond segment
Outward flange.
Further, the crescent moon opening direction of described crescent shaped groove one and crescent shaped groove two is all towards diamond segment
Inward flange.
Further, between the structure of the crescent shaped groove one of diamond segment both sides, crescent shaped groove two and straight-line groove
Every arrangement.
Further, between two adjacent crescent shaped groove two, scalloped recess is set.
Further, approximation pentagon groove is set between two adjacent crescent shaped groove two.
Further, described crescent shaped groove one, crescent shaped groove two, straight-line groove, the degree of depth of scalloped recess are gold
The 1/25～1/3 of diamond tool bit thickness.
Further, described crescent shaped groove one, crescent shaped groove two, straight-line groove, the degree of depth of approximation pentagon groove
It is the 1/25～1/3 of diamond segment thickness.
Further, described crescent shaped groove one is to the closest approach distance diamond segment inner edge of diamond segment inward flange
The distance of edge is more than 2mm.
Owing to using technique scheme, have the beneficial effects that produced by this utility model:
This utility model is arranged along the diamond segment equally distributed two groups of crescent shaped groove of circumference, with traditional saw blade
Phase specific volume bits ability improves more than 2 times；Coordinate straight-line groove and the scalloped recess between adjacent crescent shaped groove, saw blade
Hold bits, chip removal ability is greatly improved.
In this utility model, the area of the ripple struction that crescent shaped groove coordinates with straight-line groove accounts for whole diamond segment
More than the 30% of area, groove has enough chip spaces, it is not necessary to from diamond segment external diameter, straight-line groove is extended to diamond
Cutter head internal diameter, intensity and the sharpness of diamond segment are guaranteed.Bits ability of holding and the straight-line groove of crescent shaped groove
Chip removal ability combines, and makes the serviceability of saw blade be improved.
In this utility model, institute is fluted is all arranged in beyond diamond segment and saw bit matrix bonding region, will not go out
Now make the thinning phenomenon of the diamond knife head material of diamond segment and saw bit matrix bonding region, Buddha's warrior attendant due to the existence of groove
Stone cutter head is greatly improved with the adhesive strength of saw bit matrix.
The angle of four the groove incision cutting objects often organizing ripple struction in this utility model is different, and the vibration caused is not
With, reduce the probability producing resonance；The side of two crescent shaped groove is smooth surface, plays the effect progressively cut,
Alleviate vibration and impact, improve stationarity during saw blade cutting.
