Abstract

The invention discloses a manufacturing method of a geological exploration drill. The manufacturing method comprises the following steps: after uniformly mixing 52-56 percent of diamond powder and 44-48 percent of titanium according to proportion, adding a catalyst of which the weight is 0.35-0.39 percent of that of total materials, putting into a vacuum furnace to keep for 64-68 minutes; then, putting into a cubic synthetic diamond press to perform high-temperature high-pressure synthesis, after releasing pressure, covering on an alloy matrix to obtain a diamond compact, after machine-shaping, mounting on a drill rod to obtain the geological exploration drill. The geological exploration drill manufactured by the method is good in stability, good in impact toughness, high in abrasive resistance and low in abrasive ratio.

Description

technical field [0001] The invention relates to a method for manufacturing a geological exploration drill bit. Background technique [0002] At present, diamond composite sheets are widely used in geological exploration drill bits. Composite drill bits for geological survey and exploration, suitable for soft to medium hard rock formations. Diamond is known for its high hardness, high modulus of elasticity, and high thermal conductivity. At present, processing tools are mainly impregnated with single crystal diamond, and sintered polycrystalline diamond tools are booming. Sintered polycrystalline diamond is mainly a diamond composite sheet formed by a mixture of single crystal diamond particles and metal powder or by covering prefabricated alloy sheets on single crystal diamond particles. Polycrystalline Diamond Compound (PDC) has good wear resistance, thermal stability, compressive strength and impact toughness. However, the performance of the geological exploration dril...
