Abstract
The utility model relates to an integrated steel PDC drill bit, which comprises an upper body and a lower body. An upper end of the upper body is provided with screw threads. The lower part is provided with cutting teeth. The centers of the upper and lower bodies are provided with water holes. An upper part of each water hole is a straight hole, while a lower part radially inclines. The upper and lower bodies are processed and completed at one time into a whole integrated structure to form the steel PDC drill bit. The integrated steel PDC drill bit adopts the integrated structure, can be processed and molded at one time, has the characteristics of few working procedures, little difficulty, high accuracy, good quality, rapid velocity when the drill bit is pulled out during drilling, high efficiency and low cost, and is widely applied to geological exploration, petroleum drilling and similar occasions.
Description
One, technical field
The utility model relates to drill bit, particularly a kind of integral type steel body PDC drill bit.
Two, background technology
Existing a kind of PDC drill bit, its structure is the two style structure that welds together after upper body and lower body process respectively, the drill bit of this structure is that engineerings such as geological prospecting, oil drilling contribute, upper body, lower body are integrally welded again after processing respectively but it exists simultaneously, and manufacturing procedure is many, difficulty is big, precision is low, efficient is low, the shortcoming of difficult quality guarantee or deficiency.
Three, summary of the invention
The purpose of this utility model provides a kind of integral type steel body diamond bit, adopts integral structure, and the steel body of whole PDC drill bit is an integral body that processes at one time, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Integral type steel body PDC drill bit described in the utility model comprises upper body and lower body, and the upper end, upper body is provided with screw thread, and lower body is provided with cutting teeth, and upper body and lower body center are provided with hydrophthalmia, and this hydrophthalmia top is straight hole, and the bottom is radial inclination.Described upper body and lower body are the integral structure of an integral body processing at one time, form steel body PDC drill bit.
Wherein, on the described lower body carcass is installed, forms matrix drill bits.Described carcass is installed on the bottom of lower body, constitutes one with upper body and lower body.
The utility model has following advantage compared with prior art:
1, adopt integral structure, can disposable machine-shaping, manufacturing procedure is few, difficulty is little, precision is high, quality is good.
Speed was fast when 2, the drill bit drilling well tripped out, efficient is high, cost is low.
Four, description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model
Fig. 2 is an another kind of example structure schematic diagram of the present utility model
Five, the specific embodiment:
Consult accompanying drawing, a kind of integral type steel body PDC drill bit comprises upper body 1 and lower body 2, and 1 upper end, upper body is provided with screw thread, and lower body 2 is provided with cutting teeth, and upper body 1 and lower body 2 centers are provided with hydrophthalmia 3, and these hydrophthalmia 3 tops are straight hole, and the bottom is radial inclination.Upper body 1 and lower body 2 forms steel body PDC drill bit for the integral structure of an integral body processing at one time.
