Specific embodiment
The two-sided leaf-teeth dry chip of the utility model is further elaborated below with reference to specific embodiment, to right
The technical solution of the utility model makes more complete and clear explanation.
Embodiment 1
Fig. 1-4 shows the two-sided leaf-teeth dry chip of the utility model, including matrix 10 and diamond segment 20.Diamond
The non-cutting face side of cutter head is internally provided with T-slot.And described matrix 10 includes matrix bodies 12 and is arranged on matrix sheet
Flange 11 on 12 outer edge of body.The T-slot set inside the flange 11 and the non-cutting face side matches, described convex
The thickness of edge 11 is less than the thickness of described matrix ontology 12.The diamond segment 20 includes spaced first diamond tool
First 21 and second diamond segment 20.As shown in the figures 1 and 2, first diamond segment 21 is by multiple cutters tooth being arranged side by side
Composition, tooth socket is provided between the equal length of the multiple cutter tooth and adjacent cutter tooth；First diamond segment
The central axial direction of cutter tooth and described matrix are radially staggered certain angle, the angle ranging from 0-45 °, preferably 5 °-
40 °, more preferably 10 ° -30 °.If the angle that the two is staggered be more than 45 °, will cause stock-removing efficiency significantly reduce because rather than
Preferably.And if central axial direction is with radial parallel (angle being staggered is 0), not only cutting effect is poor, nor
Conducive to grinding.Tooth socket on first diamond segment is made of the first different tooth socket of depth and the second tooth socket；Wherein institute
The depth for stating the first tooth socket is more than the depth of the second tooth socket, and the first tooth socket is close to the cutwork face of the first diamond segment
Side, and second tooth socket is so designed that the chip removal that not only ensure that under the conditions of high-speed cutting close to matrix outer edge side,
And it is also beneficial to maintain the rigidity of diamond segment entirety, concrete, ceramics are able to maintain that when materials are cut higher
Cutting speed.Second diamond segment 22 is made of multiple cutters tooth being arranged side by side, and is equipped between adjacent cutter tooth
Tooth socket, wherein the cutter tooth length between both ends is more than the cutter tooth length at both ends and forms the protrusion extended towards matrix direction
Portion, the internal stress generated in working angles is transmitted along the cutwork of diamond segment towards protruding portion, distribution and is dissipated, and
Prevent internal stress from being accumulated near the bottom of slot, it can be to avoid the problem of Cracking under high-speed cutting.And it is formed in described matrix
With the matched inner fovea part of protruding portion of second diamond segment, compared to common circular arc faying face, significantly improve
The area of faying face, so as to also improve bond strength.First diamond segment is mainly used for cutting, and second gold medal
Diamond tool bit takes into account cutting and grinding, and the two mutual cooperation can play excellent ground effect.Specifically, second gold medal
The central axial direction of the cutter tooth of diamond tool bit and described matrix are radially staggered certain angle, the angle ranging from 0-45 °, excellent
It is selected as 5 ° -40 °, more preferably 10 ° -30 °.If the angle that the two is staggered be more than 45 °, will cause stock-removing efficiency significantly reduce because
Rather than preferably.And if central axial direction is with radial parallel (angle being staggered is 0), not only cutting effect is poor, and
And also it is unfavorable for grinding.Tooth socket on second diamond segment is made of the first different tooth socket of depth and the second tooth socket；
The depth of wherein described first tooth socket is more than the depth of the second tooth socket, and the first tooth socket is close to the cutting of the first diamond segment
Working face side, and second tooth socket is close to matrix outer edge side.It sees on the whole, first diamond segment and
The central axial direction of the cutter tooth of two diamond segments is equal with the angle being radially staggered of described matrix.First diamond
The surface area of cutter head and the second diamond segment is essentially identical or the surface area of the second diamond segment is slightly larger than described first
The surface area of diamond segment.Such as the surface area of second diamond segment can be the first diamond segment surface area
100-120%, the surface area of the second diamond segment is set as above range, it is ensured that the smooth work of dry chip has
Conducive to the ground effect for maintaining high speed.
Diamond segment (the first and second diamond segments) can be used well known method with matrix and be combined together, such as
It can be incorporated on the flange of matrix by way of hot pressed sintering or welding (being preferably brazed).It is smaller for matrix size
Dry chip, conventional hot-pressing sintering method usually can be used in order to reduce cost.And in order to ensure matrix and diamond segment
Bond strength can be used soldering (such as vacuum brazing, induction brazing, laser soldering etc.) technique.The base in the present embodiment
Body usually may be used steel, such as 65Mn steel etc. is obtained by mechanical processing (such as in being formed by machining process
Recess portion and flange and the mounting hole at center).And metallic bond and artificial diamond can be used in the diamond segment
Grain is formed, such as common iron-based, copper may be used by way of dispensing, mixing cold pressing, hot pressed sintering (or being freely sintered)
Base or cobalt-based metallic bond are strong in order to improve the combination between its grinding performance, especially diamond and diamond bonding agent
Prealloy powder and the form of metal powder blending preferably can be used in degree.
Diamond segment can be prevented under the working condition that the two-sided leaf-teeth dry chip of the utility model is cut in high-speed dry
It bursts apart and is broken, service life is effectively ensured, and the surface after cutting substantially increases without carry out finishing again and cuts effect
Rate.
For the ordinary skill in the art, specific embodiment has only carried out exemplary retouch to the utility model
It states, it is clear that the utility model specific implementation is not subject to the restrictions described above, as long as employing the methodology of the utility model
Improvement or not improved that the design of the utility model and technical solution is direct with the various unsubstantialities of technical solution progress
Applied to other occasions, it is within the protection scope of the utility model.
