Abstract
The utility model discloses an impregnated diamond clad sheet drill which comprises a drill body and a drill cutting body, wherein cutting teeth arranged on the drill cutting body are distributed along a top surface circle of the drill cutting body in clearance mode, the section of the cutting teeth is ladder-shaped and the cutting edge of the cutting teeth is perpendicular to an axis of the drill body. Diamond clad sheets are embedded in the center of the drill cutting body and the cutting edge of the cutting teeth. The impregnated diamond clad sheet drill is simple in structure and easy to process. The structure of a drill and embedded positions of the diamond clad sheets are improved, the cutting efficiency of the drill is effectively improved and therefore the impregnated diamond clad sheet drill can adapt to drillings of stratums with high hardness.
Description
Technical field
The utility model relates to a kind of drill bit, is specifically related to a kind of impregnated type diamond compact bit that is applied in the oil drilling industry.
Background technology
The impregnated type diamond compact bit is oil drilling industry a kind of drilling tool commonly used, and along with the development of this technology, very large variation has occured for the structure of drill bit and manufacture craft, and anticorrosive and shock resistance all greatly improves.But when the higher stratum of hardness was drilled, the cutting teeth wear intensity of drill bit was higher, has badly influenced its stock-removing efficiency.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, impregnated type diamond compact bit that the Cutter wear rate is lower is provided.
A kind of impregnated type diamond compact bit, comprise drill body and bit cutting body, cutting teeth on the described bit cutting body distributes along the end face circumferential clearance of bit cutting body, the cross section of this cutting teeth is trapezoidal, the axis of its cutting edge and drill body is perpendicular, and the middle part circle centre position of described bit cutting body and the cutting edge place of cutting teeth all are embedded with diamond compact.
The utility model is simple in structure, and is easy to process, by improving to the structure of drill bit and to the embedded location of diamond compact, Effective Raise the stock-removing efficiency of drill bit, make it more adapt to probing to the higher stratum of hardness.
On the description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of impregnated type diamond compact bit that the utility model provides, comprise drill body 1 and bit cutting body 2, referring to Fig. 2, cutting teeth 3 on the described bit cutting body 2 distributes along the end face circumferential clearance of bit cutting body 2, the cross section of this cutting teeth 3 is trapezoidal, and its cutting edge 4 is perpendicular with the axis of drill body 1, and cutting edge 4 places of the middle part circle centre position of described bit cutting body 2 and cutting teeth 3 all are embedded with diamond compact 5.
Claims (1)
