Abstract

The utility model discloses a fluted gear drill bit, which comprises a matrix, wherein tooth-shaped structures are uniformly distributed on the end part of the matrix, a water gap is arranged between the adjacent tooth-shaped structures, a plurality of teeth are distributed on each tooth-shaped structure, and a groove is arranged on the end surface of each tooth. The utility model has reasonable and ingenious structural design, because the end surface of the matrix is of a tooth-shaped structure with the groove, the contact area of the end surface and the rock is small during the work, the local pressure is increased under the same drilling pressure, the matrix can rapidly edge the rock during the work, and the stability during the work is further improved due to the existence of the groove and the increase of the water gap, the scouring speed of rock powder is also increased, and the edge-cutting and working efficiency of the drill bit is greatly improved.

Description

Fluted gear drill bit

Technical Field

The utility model relates to a fluted gear drill bit.

Background

The end face of the tire body of the common drilling tooth is flat and is provided with a water outlet, so that water flow carries rock powder to flow out, but the contact pressure between the end part of the plane and rock is small, so that the cutting speed is low in the working process, and the working efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a fluted gear drill bit, which can lead a matrix to quickly break off edges with rocks during working and greatly improve the working efficiency of the drill bit.

In order to realize the purpose, the structure adopted by the utility model is as follows: grooved gear drill bit, including the matrix, the equipartition has dentate structure on the matrix tip, arranges 1 ~ 3 teeth on every dentate structure, is equipped with the mouth of a river between the adjacent dentate structure.

And grooves are arranged on the end surfaces of the teeth of the tooth-shaped structures.

The beneficial effects are as follows: the utility model has reasonable and ingenious structural design, because the end surface of the matrix is of a tooth-shaped structure with the groove, the contact area of the end surface and the rock is small during the work, the local pressure is increased under the same drilling pressure, the matrix can rapidly edge the rock during the work, and the stability during the work is further improved due to the existence of the groove and the increase of the water gap, the scouring speed of rock powder is also increased, and the edge-cutting and working efficiency of the drill bit is greatly improved.

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 diagram of the present invention.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The grooved gear drill bit shown in fig. 1 comprises a tire body 1, wherein tooth-shaped structures 2 are uniformly distributed on the end part of the tire body 1, 1-3 teeth are distributed on each tooth-shaped structure 2, and a water gap 3 is arranged between every two adjacent tooth-shaped structures 2.

Grooves 4 are arranged on the end faces of the teeth of the toothed structure 2.

The utility model has reasonable and ingenious structural design, because the end surface of the matrix is of a tooth-shaped structure with the groove, the contact area of the end surface and the rock is small during the work, the local pressure is increased under the same drilling pressure, the matrix can rapidly edge the rock during the work, and the stability during the work is further improved due to the existence of the groove and the increase of the water gap, the scouring speed of rock powder is also increased, and the edge-cutting and working efficiency of the drill bit is greatly improved.

The utility model is not limited to the foregoing embodiments. The utility model extends to any novel feature or any novel combination of features disclosed in this specification and any novel method or process steps or any novel combination of features disclosed.

Claims

1. The fluted gear drill bit comprises a matrix and is characterized in that tooth-shaped structures are uniformly distributed on the end part of the matrix, 1-3 teeth are distributed on each tooth-shaped structure, a water gap is arranged between every two adjacent tooth-shaped structures, and grooves are formed in the end faces of the teeth of the tooth-shaped structures.
