Abstract

The invention discloses a production process of a multi-layer brazed diamond hole drill. The production process comprises the following preparation steps: preparing abrasive blocks; adding the abrasive blocks prepared from raw materials in parts by weight into a stainless steel reaction kettle, mixing, taking out, drying and cooling; smashing and screening the cooled abrasive blocks to obtain powdery abrasive blocks; feeding the abrasive blocks; firstly, coating the outer wall of the bottom of a hole drill base body with a glue solution, loading the powdery abrasive blocks into an open tank and below the hole drill base body, and placing a magnet at the top end of the hole drill base body so that the hole drill base body generates magnetism; then, placing the bottom of the hole drill base body above the abrasive blocks so that the abrasive blocks are adsorbed on the outer wall of the hole drill base body in a layered mode; and brazing the abrasive blocks to the hole drill base body to obtain a diamond hole drill body. According to the production process, the abrasive blocks are distributed on the hole drill in a multi-layer form, so that the hole drill has very high strength and long service life during use; and the preparation process is simple.

Description

technical field [0001] The invention belongs to the technical field of drill bits, in particular to a production process of a multi-layer brazing diamond hole drill. Background technique [0002] The main function of the drill bit is to break the rock, form a wellbore and drill a hole in a hard object. [0003] The multi-layer structure of the existing hole drill: the way of pointing is adopted, grooves and gaps are opened on the substrate, and the diamond material is welded and embedded into the substrate. This preparation process has the problems of complicated production and high requirements for the substrate material. . Contents of the invention [0004] The purpose of the present invention is to solve the multi-layer structure of the existing hole drill: adopt the way of pointing, open grooves and slits on the substrate, and weld and embed the diamond material on the substrate. This preparation process has complex production, In order to solve the problem of high r...
