Abstract
The utility model discloses a diamond saw bit cutting head and belongs to the technical field of cutting tools. The diamond saw bit cutting head comprises a cutting head which is formed by sintering of alloy powder and diamond particles arranged in the alloy powder, wherein the diamond particles are orderly arranged in a centrifugal mode along the cutting direction of the cutting head, an alloy powder block is formed by mould pressing of the alloy powder, the diamond particles are arranged on the alloy powder block, and the cutting head is formed by overlying and sintering of multiple layers of alloy powder blocks containing the diamond particles. The diamond particles are reasonable in arrangement, and the diamond cutting head is high in cutting efficiency and long in service life.
Description
Technical field
The utility model relates to a kind of cutting tool, specifically a kind of diamond saw blade.
Background technology
Diamond saw blade is comprised of matrix and cutter head two parts usually.Be provided with diamantiferous cutter head in the circle on the excircle of matrix.Its cutter head of traditional diamond saw blade generally is to add certain density diamond particles in alloyed powder, adopts the mode of mechanical batch mixing again, and after both were mixed, sintering formed in the mould of packing into.Because the proportion of diamond particles and alloyed powder differs larger, therefore the diamond particles distribution density in traditional diamond saw blade is uneven, and diamond particles also is arbitrarily to arrange in the exposed locations of cutter head, so there is following problem in existing diamond saw blade: first, when the diamond particles of cutter head cutting part on the diamond saw blade is too lax, can affect the cutting dynamics of cutter head; And when the diamond particles of cutter head cutting part is too dense, can cause again the diamond contact area excessive and produce larger resistance, and also can cause local temperature too high simultaneously, cause the diamond carbonization, cutting efficiency reduces.The second, when the diamond particles at cutter head position is exposed insufficient, make diamond particles can not effectively participate in cutting, and the exposed too much position of diamond on the cutter head, diamond can come off prematurely, has affected thus cutting efficiency and the service life of saw blade.
The utility model content
It is rationally distributed that the utility model technical issues that need to address provide a kind of diamond particles, and cutting efficiency is high, the diamond saw blade of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of diamond saw blade comprises that described diamond particles is centrifugal shape ordered arrangement along the cutter head cutting direction by alloyed powder and be arranged in the cutter head that the diamond particles sintering in the alloyed powder forms; Described alloyed powder is the alloy powder block that mold pressing forms, and arranges diamond particles on the alloy powder block, and the alloy powder block that described cutter head contains diamond particles through multilayer laminates sintering and forms.
Further improvement of the utility model is: the arranging density of the outer diamond particles of described cutter head is greater than the arranging density of internal layer diamond particles.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
Diamond particles in the diamond saw blade of the present utility model, cutter head is centrifugal shape ordered arrangement along the cutter head cutting direction, and every diamond particles all can participate in the rotation of saw blade cutting, the service life that is conducive to improve cutter head successively.The alloy powder block that cutter head contains diamond particles by multilayer laminates sintering and forms, can manual control diamond particles arranging in cutter head, make the exposed ratio of the diamond particles that participates in cutting consistent, each cutter head can evenly cut and wear and tear, to prolong the service life of cutter head.In addition, diamond particles arranging in cutter head adopts internal layer sparse, and outer dense mode not only can increase the intensity of cutter head, can also increase the cutting power on cutter head top layer, increases the wearability of cutter head, thereby improves stock-removing efficiency, increases the service life.Arranging of moderate reduction internal layer diamond particles not only can reduce the cost, and after the outer wearing and tearing of cutter head, internal layer can also play polishing action.

Wherein, 1, diamond particles, 2, alloy powder block, 2-1, skin, 2-2, internal layer.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further details:
As shown in Figure 1, a kind of diamond saw blade is formed by alloyed powder and diamond particles 1 sintering that is arranged in the alloyed powder, and alloyed powder is the alloy powder block 2 that mold pressing forms, and diamond particles 1 is centrifugal shape ordered arrangement along the cutter head cutting direction.Carrying out diamond particles 1 when arranging, the screen cloth that is provided with corresponding locating hole can be placed on the alloy powder block 2, again diamond particles 1 is distributed in the locating hole, so after the distribution multilayer, make up, sintering, behind the tool-tip sintering forming, be welded to again on the cutter hub of diamond saw blade.The screen cloth that the utility model adopts is the screen cloth that centrifugal shape ordered arrangement locating hole is arranged along the cutter head cutting direction, to guarantee that diamond particles 1 can be arranged on the alloy powder block 2 in an orderly manner with centrifugal shape.After the utility model was made moulding, every diamond particles 1 can both participate in successively along with the rotation of saw blade cutting, thus Effective Raise the utilization rate of diamond particles, and reduced to have reduced the generation of collapsing the limit phenomenon to being cut the impact of material.
Section of the present utility model as shown in Figure 2, the alloy powder block 2 that diamond saw blade contains diamond particles 1 by multilayer laminates sintering and forms.During making, place the screen cloth that contains different sieve aperture density at different-alloy powder agglomates 2 first, be to place the large screen cloth of sieve aperture density on the outer layer alloys powder agglomates 2, place the little screen cloth of sieve aperture density on the inner alloy powder agglomates 2, then arrange diamond particles in the sieve aperture, the alloy powder block 2 that at last these is accompanied multilayer different densities diamond particles 1 is pressed the stacked cutter head that sinters into.The result who arranges like this is: the arranging density of the outer 2-1 diamond particles 1 of cutter head does not contain diamond particles 1 greater than the arranging density of internal layer 2-2 diamond particles 1 in the alloy powder block 2 of middle, and the intermediate layer is used for cutter head is welded to cutter hub.The utility model adopts sandwich construction, can manual control diamond particles 1 arranging in cutter head, and make diamond particles 1 be centrifugal shape ordered arrangement along the cutter head cutting direction, realize simultaneously outer intensive, arrangement mode that internal layer is sparse.The wearing and tearing of cutter head mainly are two sides, the arranging density of the outer 2-1 diamond particles 1 of cutter head can increase the wearability of cutter head greater than the arranging density of internal layer 2-2 diamond particles 1, makes cutter head have good cutting efficiency, prolong the service life of cutter head, and reduce and use adamantine cost.
