Abstract
The utility model relates to a novel diamond bit, which comprises a cutter head 1, a steel body 2 and a connecting head 3, wherein the cutter head 1 is shaped through evenly mixing diamond particles and metal powder and then sintering through the powder metallurgy technique, the cutter head 1 and the steel body 2 are welded together through laser beam welding or high frequency welding, and the cutter head 1 is an unfilled corner turbine type indexing structure. The connecting head 3 is connected with the steel body and an electric tool. The utility model has the beneficial effects that the diamond bit with the structure style has little resistance in cutting diamond, the chip removal is easy, the sharpness is high, the defects that an existing diamond bit has slow drilling speed in primary drilling and the like are overcome, and the diamond bit can be used in the drilling manufacture of various brittle and hard materials.
Description
Technical field
The utility model relates to a kind of diamond bit, and particularly a kind of unfilled corner turbine type is divided the novel diamond bit of toothing, can be widely used in the boring processing of various crisp and hard materials.
Background technology
In the prior art, the boring machining tool of crisp and hard material mostly adopts the diamond bit of common cutter head, and resistance was big when there was punching in this drill bit, was difficult for chip removal, sharpness low and when initially punching rate of penetration waits deficiency slowly.
The utility model content
The purpose of this utility model is: overcome the defective of prior art, a kind of sharpness height is provided, resistance is little, easily chip removal, and the fast novel diamond bit of rate of penetration when initially punching, the boring that is specially adapted to various crisp and hard materials is processed.
The technical solution of the utility model is: a kind of novel diamond bit, comprise cutter head 1, steel body 2, adaper 3, and steel body 2 is a tubular structure, and the one end is provided with cutter head 1, and the other end is provided with adaper 3, and adaper 3 links together steel body 2 and electric tool; Cutter head 1 divides toothing for the unfilled corner turbine type, and its top is the unfilled corner form of cross symmetry, respectively is provided with some turbine grooves below two unfilled corners.
The beneficial effects of the utility model are: resistance is little during the diamond bit drilling of this version, easily chip removal, sharpness height.Rate of penetration waits defective slowly when having overcome existing diamond bit and initially punching, and can be used for the boring processing of various crisp and hard materials.

The specific embodiment
Figure of description is an enforcement preferred version of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2: comprise cutter head 1, steel body 2, adaper 3.Cutter head 1 is mixed by diamond particles and metal dust after the powder metallurgical technique sinter molding, and cutter head 1 is welded together by Laser Welding or ratio-frequency welding with steel body 2.Cutter head 1 divides toothing for the unfilled corner turbine type, and its top is the unfilled corner form of cross symmetry, and (on inner arc surface and the exterior arc surface) respectively has some turbine grooves (as Fig. 3,4,5,6) below two unfilled corners.Thereby drill bit when work, the unfilled corner part at top is the contact machined material earlier, and contact area is significantly smaller than common cutter head, cutting resistance reduces, and sharpness improves, and rate of penetration is accelerated, and drill bit impact power is reduced when initially punching, the accuracy of punching location is improved.Two turbine grooves are positioned at the below of unfilled corner, directly fall to lead to two unfilled corners, so are very beneficial for chip removal in the boring procedure, have improved drilling efficient; The existence of other two turbine grooves has strengthened the surface area of cutter head virtually, helps the cutter head heat radiation, thus the service life of having improved drill bit.
