Description

A kind of drill bit

Technical field

This utility model is related to a kind of drill bit.

Background technology

A kind of existing drill bit, includes matrix, and matrix is provided with cutting face, and described cutting face is provided with a knife Sword, but, the drill bit of this structure, its structure is excessively simple, and during cutting, impact velocity is slow, and efficiency is low；And, during cutting, cut The periphery of bevel easily and is cut friction between thing, produces fragment, leads to precision during the operations such as boring low.

Content of the invention

The purpose of this utility model: in order to overcome the defect of prior art, this utility model provides a kind of drill bit, its punching Hit speed fast, efficiency high；And, it is avoided that fragment produces it is ensured that its operating accuracy is high.

The technical solution of the utility model: a kind of drill bit, include matrix, matrix be provided with cutting face it is characterised in that: Described cutting face include the first cutting basal plane, second cutting basal plane, the 3rd cutting basal plane and the 4th cutting basal plane, first Cutting basal plane, the second cutting basal plane, the 3rd cutting basal plane and the 4th cutting basal plane are all obliquely installed, the first cutting basal plane, the The two cutting right settings of basal plane one the first from left, the 3rd cutting basal plane is located at below the first cutting basal plane, and the 4th cutting basal plane is located at second Below cutting basal plane, the first cutting basal plane and the second cutting basal plane are crossed to form the first blade, and the 3rd cutting basal plane is cut with the 4th Cut basal plane and be crossed to form the second blade, the first cutting basal plane and the 4th cutting basal plane are crossed to form the 3rd blade, the first cutting base Face is crossed to form the 4th blade with the 3rd cutting basal plane, and the second cutting basal plane and the 4th cutting basal plane are crossed to form the 5th blade, It is respectively equipped with first slope, the second slope in described first cutting basal plane, the outer side edges of the 4th cutting basal plane.

Using technique scheme, the first blade of setting, the second blade, the 3rd blade, the 4th blade and the 5th knife Sword, can greatly improve the impact velocity of drill bit, high in machining efficiency；The slope of setting, can improve the impact of drill bit further Speed, can also protect the periphery in cutting face well, prevent fragment from producing it is ensured that machining accuracy.

Of the present utility model arrange further: described the first blade, the longitudinally parallel setting of orthographic projection of the second blade, The orthographic projection of the 3rd blade is obliquely installed, and the 4th blade, the orthographic projection of the 5th blade transversely be arranged in parallel.

Arranged further using above-mentioned, this blade set-up mode, so that during bit operation, can carry out from multi-angle Cutting, cutting speed is fast, efficiency high.

Further setting of the present utility model: it is opposite with the second cutting basal plane that first slope is arranged on the first cutting basal plane Side on, the second slope is arranged on the 4th cutting basal plane and cuts on the opposite side of basal plane with the 3rd.

Further arranged using above-mentioned, the impact velocity of drill bit is fast, can be better protected from the generation of fragment during work.

Brief description
