Abstract
Disclosed is a diamond aiguille, belonging to the technical field of drilling tools. The diamond aiguille comprises a tool bit and a steel base body; the tool bit is sintered from the mixture of diamond particles and metal powder through powder metallurgy technique; and the tool bit and the steel base body are welded together. The top edge of the tool bit(1)takes the shape of a fastigium; three V-shaped gaps in staggered arrangement are distributed on the side face of the tool bit(1); two of the V-shaped gaps face the cutting surface and the other V-shaped gap faces the welding surfaces of the tool bit and the base body, taking the shape of W. The diamond aiguille is applicable for processing bores on various fragile and hard objects like stones, ceramic tiles, concrete structures and asphaltum structures. The diamond aiguille has the advantages that the fastigium on the top cutting edge is good for positioning during the drilling process and ensures the cutting speed; and the gaps at the side face of the tool bit of the aiguille are good for removing the chips and reducing the contact area between the side face of the tool bit and the material to be cut. Therefore, the friction is reduced during the saw cutting process and the chip removal and cooling capabilities are improved, thereby improving the sharpness of the tool bit.
Description
Technical field
The utility model belongs to the drilling tool technical field, particularly a kind of diamond bit, be applicable to the boring processing of various stone materials, xoncrete structure and bituminous texture.
Background technology
Diamond segment and steel matrix are solidly fixed by welding manner and have just formed diamond bit.At present, it is circular-arc using the most general bit wing head shapes, there is the centralized positioning difficulty in this drill bit, and the contact area of cutter head and sawing material is big, and the drag loading that causes drilling to produce is big, rate of penetration is slow, particularly under the condition of drilled dry, its chip removal and cooling capacity are poor, and the heat that drilling produces can not in time leave, cause in the cutter head diamond because of ablation intensity descends, fragmentation, the processing of can not holing effectively.
Summary of the invention
The purpose of this utility model is to provide a kind of diamond bit, has overcome existing drill bit because of ablation intensity descends, the defective of fragmentation.Realized that centralized positioning is easy, the external form grace is cut sharply, and chip removal is smooth and easy, safety and stability.
The utility model comprises cutter head and steel matrix.Cutter head adopts powder metallurgical technique to be mixed after Thermocompressed sintering and forming by metal dust and diamond particles; steel body and cutter head are linked together; it is characterized in that: cutter head top sword is the pinnacle shape; the cutter head side is distributing three and is being the staggered v-notch of arranging; wherein two v-notch are opened to cut surface; v-notch is towards the solder side of cutter head and matrix, similar W shape
Cutter head is the caking formula, and quantity is the 2-20 joint, can weld with common diamond segment is staggered.
Advantageous effects
When helping drilling, the pinnacle of the utility model drill bit on the sword of cutting top locate, improve cutter speed down, breach in drill bit cutter head side helps chip removal and reduces the cutter head side and the contact area of sawing material, also just reduced the frictional force between sawing, increase chip removal and cooling capacity, thereby improved the sharpness of cutter head.

Fig. 1 pinnacle diamond bit structural representation.Wherein, cutter head 1, steel matrix 2.
Fig. 2 is the structural representation of pinnacle drill bit cutter head.Wherein, cutter head top 11, v- notch 12,13,14
Fig. 3 is the schematic diagram of caking formula for diamond bit cutter head of the present utility model.Wherein, cutter head 1, steel matrix 2, common cutter head 3.
The specific embodiment:
Further specify the utility model below in conjunction with accompanying drawing.
Diamond bit is made up of steel matrix and diamond segment two parts, and as shown in Figure 1, cutter head 1 adopts powder metallurgical technique to be mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and steel matrix 2 welds together with cutter head 1.The partial schematic diagram of drill bit cutter head 1 is seen Fig. 2,11 places are the pinnacle shape at the diamond segment top, 3 v- notch 12,13,14 are distributing in the side of cutter head, the V-type mouth of v- notch 12,14 is opened to cutting top sword, the breach of v-notch 13 is opened the solder side direction at cutter head and matrix, and v-notch 13 is positioned at the centre of v-notch 12 and v-notch 14.
Diamond bit cutter head of the present utility model is the caking formula, available diamond segment 1 of the present utility model and the alternately welding of common cutter head 3, as shown in Figure 3.
Claims (2)
1, a kind of diamond bit, comprise cutter head, steel matrix, cutter head is mixed by diamond particles and metal dust after the powder metallurgical technique sinter molding, and cutter head and steel matrix weld together, and it is characterized in that: cutter head (1) top sword is the pinnacle shape, the distributing v-notch of three interlaced arrangement of cutter head (1) side, wherein two v-notch are towards cut surface, and v-notch is the W shape towards the solder side of cutter head and matrix.
2, diamond bit according to claim 1 is characterized in that, cutter head (1) is the caking formula, and quantity is the 2-20 joint, with the staggered welding of common diamond segment (3).
