Problems solved by technology

However, these impregnated diamond bits have a common disadvantage when drilling into hard and abrasive formations: the drill bit loses its original function after the shape of its bottom lip is worn, unlike ordinary flat bottom and arc bottom lip impregnated diamond bit
The disadvantages of ordinary flat-bottomed diamond-impregnated drill bits are short service life, low drilling efficiency, high processing cost and high unit footage cost, especially when drilling deep or ultra-deep holes due to the wear and tear of the drill bit, it is necessary to continuously extract the drill bit. It took a lot of time and caused a lot of manpower and financial resources consumption

Embodiment 1

[0021] Take 20% of 80-mesh diamond and 50% matrix material by volume to fully mix into wear-resistant material 4, then mix 30% of quartz particles with a diameter of 2mm evenly, and make the quartz particles randomly distribute on the diamond according to the proportion of 15% of the bottom area. The mixture with the carcass material becomes the material of the working layer 3, and the material of the working layer 3 is evenly put into the graphite mold for compaction, and then the transition layer 2 is added on it, and then compacted, put into the steel body 1, and dried at the temperature 900℃, pressure at 160Kgf / Cm 2 It is hot-pressed under the condition of heat-preservation material, cooled slowly to room temperature in the heat preservation material, and the nozzle and thread are processed, which is the diamond-impregnated biomimetic drill bit. The specifications of drill bit, saw blade and grinding head can be designed arbitrarily.

Embodiment 2

[0023] Take 25% graphite by volume to make a graphite column with a diameter of 2mm and a length equal to the thickness of the working layer 3. The graphite column is concentrically fixed in a graphite mold in a ratio of 30% of the bottom area, and 25% of a 75-mesh diamond is taken. Fully mix with 50% carcass material to form wear-resistant material 4, fill in between graphite columns, add transition layer 2 on top after compaction, and then compact, put into steel body 1, after drying at temperature 950°C, pressure at 150Kgf / Cm 2 It is hot-pressed under the condition of heat-preservation material, cooled slowly to room temperature in the heat preservation material, and the nozzle and thread are processed, which is the diamond-impregnated biomimetic drill bit. The specifications of drill bit, saw blade and grinding head can be designed arbitrarily.

Embodiment 3

[0025] Get 25% diamond polycrystal by volume and make diameter be 2mm, length is equal to the diamond polycrystal pillar of working layer 3 thickness, by occupying the ratio of 40% of bottom area, diamond polycrystal pillar is fixed in the mold with rhombus distribution, takes by volume 70-mesh diamond 17% and 58% carcass material are fully mixed to form wear-resistant material 4, filled between diamond polycrystalline columns, after compaction, a transition layer 2 is added on top, and then compacted, put into steel body 1, after drying Temperature 1000℃, pressure 140Kgf / Cm 2 It is hot-pressed under the condition of heat-preservation material, cooled slowly to room temperature in the heat preservation material, and the nozzle and thread are processed, which is the diamond-impregnated biomimetic drill bit. The specifications of drill bit, saw blade and grinding head can be designed arbitrarily.

Abstract

This invention discloses a kind of bionic diamond-impregnated bit and its producing method. It uses the shape characteristic that the surface of organism is not smooth. This invention is fit for various saw blades of diamond, diamond abrasive tips and solid rock geologic drillings. This invention includes the steel body; the transition-layer; the shape material with unsmooth surface; the diamond; the carcass. The shape materials with unsmooth surfaces are distributed at working layer according to the request. Thus, it decreases the cutting adherence and cutting frictional resistance. It also increases the service life and cutting efficiency of the cutting tool. Compared with normal diamond products, this invention has long lifetime and quick drilling rate. The energy consumption is low.

Description

technical field [0001] The invention relates to a diamond drill bit suitable for drilling various bedrock geological bodies, especially a bionic diamond drill bit adopting a biological non-smooth shape. Background technique [0002] Due to the characteristics of anti-adhesion, drag reduction and wear resistance, the biological non-smooth bionic technology has become a new technology that saves material consumption, improves efficiency and reduces costs. It is playing a revolutionary role and is a new idea that is counterintuitive. Biological non-smooth shape bionic technology prevents the non-smooth surface of soil animals from being applied to the structural design of impregnated diamond bits, so as to realize the mud bag phenomenon of impregnated diamond bits, reduce the frictional resistance of impregnated diamond bits, and improve The purpose of diamond impregnated bit life and drilling efficiency. Biological non-smooth anti-adhesive drag reduction has been confirmed by...
