Description
Technical Field
The utility model relates to a drill bit with an ultrahigh matrix spiral water gap.
Background
The flow direction distribution of the water gaps on a general drill bit is narrow, and in order to enable water flowing out of the water gaps to cover the drill bit, the number of the water gaps needs to be increased, so that the strength of a steel body is reduced, the steel body is seriously abraded in the working process, and the service life of the drill bit is greatly shortened.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a drill bit with an ultrahigh matrix spiral water gap, which is used for solving the problems.
To achieve the purpose, the utility model adopts the following structure: ultrahigh matrix spiral mouth of a river drill bit, including the steel body, the top of steel body is a plurality of matrix that cyclic annular evenly arranged, is provided with the straight mouth of a river of rectangle between the adjacent matrix, and the oblique mouth of a river of a V type is connected at the top of every straight mouth of a river of rectangle.
Chip removing holes are uniformly distributed at the bottom of the tire body.
The spiral wear-resistant reinforcing ribs are welded on the steel body, and the rotating direction of the spiral wear-resistant reinforcing ribs is the same as the working direction of the drill bit.
The inner side and the outer side of the rectangular straight water port are provided with side main water ports which are arc-shaped grooves, the inner side and the outer side of the V-shaped inclined water port are provided with side auxiliary water ports which are arc-shaped grooves.
The side main water gap is arranged on one of the rectangular straight water gaps, and the V-shaped inclined water gap adjacent to the rectangular straight water gap is provided with a side auxiliary water gap.
The beneficial effects are as follows: the utility model has reasonable and ingenious structural design, the contact surface of the matrix of the V-shaped inclined water gap section is reduced, the high drilling pressure for forming initial opening is facilitated, the cutting and the opening are convenient, the matrix contact area of the rectangular straight water gap section is increased, the drill bit can work according to a normal matrix, the spiral wear-resistant reinforcing rib increases the strength of the steel body, and the spiral water gap has a certain function of accelerating the discharge of fine rock powder.
Drawings
The utility model will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a schematic perspective view of the present invention;
fig. 2 is a top view structural diagram of the present invention.
Detailed Description
