Novel drill bit matrix

Abstract

The invention discloses a novel drill bit matrix. The novel drill bit matrix is prepared from manufacturing materials in percentage by weight: 20-35% of tungsten carbide, 15-30% of ferroalloy powder,25-32% of bronze powder and 15-20% of auxiliary materials. The hardness and the abrasion resistance of the drill bit matrix are changed to a certain degree by changing the weight parts of the manufacturing materials of the novel drill bit matrix, the adopted manufacturing materials are simple and easy to obtain, and the use performance of the drill bit matrix is improved when the manufacturing cost is unchanged.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a novel drill bit matrix. Background technique [0002] Drill bits are cutting tools used by general drills or drilling machines to cut out circular holes. The commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills and trepanning drills. [0003] When the drill bit is produced, it is necessary to produce the drill bit matrix and then polish it to the required shape, but the existing drill bit production materials are mostly made of fixed parts of production materials, and their hardness and wear resistance cannot meet certain requirements. , we propose a novel bit matrix. Contents of the invention [0004] The purpose of the present invention is to provide a new drill bit matrix to solve the problems raised in the background art. [0005] In order to achieve the above object, the present invention provides the following technical...
