Manufacturing method of electroformed diamond geological drill bit with honeycomb structure

Abstract

The invention discloses a manufacturing method of an electroformed diamond geological drill bit with a honeycomb structure. The manufacturing method comprises the following steps: adding the following components: 220-250g / L of nickel sulfate, 10-15g / L of cobalt sulfate, 5-10g / L of manganese sulfate, 30-45g / L of nickel chloride, 30-40g / L of boric acid, 0.5-1.0g / L of saccharin, 0.05-0.1g / L of sodium dodecyl sulfate, 5-10g / L of ammonium chloride, and 0.2-0.5g / L of cerium oxide into per liter deionized water, and stirring and mixing to prepare an electroforming solution; putting the processed drill bit into a compound mold, then putting the compound mold into an electroplating bath, carrying out strike plating in the electroplating solution with the temperature of 20-30 DEG C through a current with the current density of 1.0-2.0A / dm<2>, then performing vacuum plating with a current with the current density of 1.5-2.0A / dm<2> to form a plated layer, and then repeatedly spreading diamond powder on a tool bit at intervals to form a diamond alloy plating layer, thus manufacturing the electroformed diamond drill bit with the honeycomb structure. The electroforming production period is shortened by at least three days; the usage amount of nickel can be reduced by 10%-20%; the drilling aging can be improved by more than 50%.

Description

technical field [0001] The invention relates to a geological drill bit, in particular to a method for manufacturing an electroformed honeycomb structure diamond geological drill bit. Background technique [0002] Electroformed diamond geological drill bits are mainly used in geological exploration, mineral prospecting and other industries to drill formation cores and analyze geological structures and mineral content in minerals. The working parts of the electroformed diamond geological drill bit (referred to as the cutter head) on the market are all solid structures, and the cutter head has a high density, while the material for electroforming to produce sticky diamond has a high nickel content, although this nickel-containing diamond drill bit wears Small size, high self-sharpening performance, and high grinding efficiency, but due to the high hardness and impact strength of nickel, it is easy to cause the edges and corners of the diamond abrasive to be blunted during the d...

AI Technical Summary

Problems solved by technology

The existing electroformed diamond geological drill bits on the market have a time limit of 1-2 m / hour for drilling common limestone, 0.6-1 m / hour for low-hardness granite, and 0-0.5 for high-hardness granite. meters per hour, and the electroforming process of electroformed diamond geological drill bits takes at least 10 days, and the cycle is relatively long. At present, the price of metal nickel continues to increase, and the consumption of metal nickel in the electroplating process is also relatively large, and the manufacturing and use costs high
