Abstract

The utility model discloses a diamond drill bit, which comprises a cutter head which is provided with sawteeth. Grooves are evenly distributed on an inner arc face and an outer arc face of the cutter head. Due to the grooves, contact area between the cutter head and cut materials is changed, resistance in cutting is reduced, and cutting sharpness is improved. Simultaneously, due to the sawteeth, end edges of all cutter heads can be quickly abraded to the same plane so as to greatly improve using performances of the drill bit.

Description

Diamond bit
Technical field
The utility model relates to a kind of diamond bit.
Background technology
Diamond bit is a kind of novel boring bar tool; Be widely used in fields such as processing of stone, building, decoration, highway construction, it is accurate to have a bore size, and speed is fast; The material periphery is not had characteristics such as damage, become the optimal selection of creeping into aperture and large diameter hole in the various constructional materialss.And at present mostly the cutter head of diamond bit commonly used is the plane, this drill bit just begin the time spent because of the end sword of each cutter head not at grade, have certain error; Cause and produce violent vibrations in use; Influence cutting performance, even the phenomenon generation that causes cutter head to burn out, and drill bit is when boring; Receive very large cutting resistance, influenced the rate of penetration of drill bit.
The utility model content
The utility model is in order to overcome the deficiency of prior art, the diamond bit of the stability when a kind of rate of penetration that can improve drill bit is provided with cutting.
To achieve these goals, the utility model adopts following technical scheme: a kind of diamond bit, comprise cutter head, and said cutter head is provided with sawtooth, and the intrados and the extrados of said cutter head are provided with groove.
On the other hand, the cross section of said groove is trapezoidal.
On the other hand, the degree of depth of said groove is 0.8-1.2mm.
The beneficial effect of the utility model is: the utility model has changed cutter head and has been cut the contact area between the material through groove is set, the resistance when having reduced cutting, thus improve the cutting sharpness; Make all cutter heads be provided with sawtooth simultaneously, the end sword that makes cutter head break-in has soon improved the functional performance of drill bit widely to same plane.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional drawing of the vertical view of cutter head 1 among Fig. 1.
Fig. 3 is the sectional drawing of the front view of cutter head 1 among Fig. 1.
The specific embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
Like Fig. 1, Fig. 2, shown in Figure 3, diamond bit comprises the cutter head 1 that is provided with sawtooth 3, is evenly equipped with groove 2 on the intrados of cutter head 1 and the extrados, and the cross section of groove 2 is trapezoidal, and the degree of depth of groove 2 is 0.8-1.2mm, is preferably 1mm.
Drill bit the time will receive very large cutting resistance in boring, and the size of resistance is cut constituent and the drill bit cutter head of object and the contact area that is cut between the material decides.The utility model has changed cutter head and has been cut the contact area between the material through on cutter head, offering groove, the resistance when having reduced cutting, thus improve the cutting sharpness; And these grooves play the effect of drainage in cutting process, make the rubble that produces in the cutting process leave face preparation from groove, have further reduced the cutting resistance, have further improved the sharpness of drill bit;
And the end sword of cutter head is provided with sawtooth, and the end sword break-in quickly that makes each cutter head is to same plane, the stability when having improved drill bit work greatly.

Claims (3)
