Problems solved by technology
As far as the prior art is concerned, the speed of the diamond drill bit is slow when drilling. The main reason is that the lip surface of the diamond drill bit has a large contact area with the rock during drilling, so that the pressure applied to the rock by the lip surface of the matrix is not enough to break it.

Abstract
The invention discloses a diamond drill bit containing a high-manganese steel cone. The drill bit comprises a steel body, a matrix body and matrix blocks, wherein the steel body is connected with the matrix body, the matrix body is annular, the matrix blocks are arranged on the matrix body annularly at an interval, each matrix block comprises a diamond matrix and a plurality of high-manganese steel cones arranged in the diamond matrix, and the heads of the high-manganese steel cones are arranged on the surface of the matrix blocks in a protruding manner. By adopting the manner, when the diamond drill bit is used for drilling, the high-manganese steel cones protrude, so that the contact area between the labinal surface of the diamond drill bit and the rock is reduced, the pressure of the labinal surface applied to the unit area of the rock is increased, and the pressure of the diamond drill bit to the rock is increased; at the same time, when high-manganese steel is subjected to impact loading, plastic deformation is generated on the surface to form a processing hardening phenomenon, so that the surface hardness is greatly increased, the wear resistance is enhanced, the rock is easily broken, the drilling speed of the drill bit is increased, and the problem that the drilling speed of diamond to medium-hard to hard rock stratum is low is solved.
Description
technical field [0001] The invention relates to the field of drill bits, in particular to a diamond drill bit containing a high manganese steel cone. Background technique [0002] At present, diamond drill bits have been widely used in municipal roads and bridges, construction, exploration and other fields. Diamond drill bits usually include a steel body and a carcass. The carcass is provided with several tire blocks, and the contact surface between the tire block and the rock is its lip surface. . For the prior art, the diamond drill bit is slow in drilling, mainly because the lip surface of the diamond bit has a large contact area with the rock, so that the pressure exerted by the lip surface of the carcass on the rock is not enough to break it. SUMMARY OF THE INVENTION [0003] The main technical problem solved by the present invention is to provide a diamond drill bit containing a high manganese steel cone, which can improve the efficiency of the drill bit by increasi...
