Abstract
The invention discloses a polycrystalline diamond-hard alloy composite rock-breaking button which comprises a hard alloy button main body (1), wherein at least one polycrystalline diamond is arranged in the hard alloy button main body (1). A polycrystalline diamond short cylinder (2) is adopted as the polycrystalline diamond, and the length and diameter of the polycrystalline diamond short cylinder arranged in a hole on the hard alloy button main body (1) are 1 to 50 millimeters and 1 to 30 millimeters respectively. The polycrystalline diamond-hard alloy composite rock-breaking button has a simple structure, is convenient to produce and process, has high impact resistance and corrosion resistance, and is suitable for being applied to rock-breaking tools used for manufacturing downhole drill bits and the like.
Description
Technical field
The present invention relates to a kind of detritus ball tooth, particularly relate to a kind of strong shock resistance, the compound detritus ball of polycrystalline diamond-carbide alloy tooth that anti-wear performance is high.
Background technology
Hard alloy spherical-teeth is a kind of material of existing impact grinding rock, with respect to other metal material, has certain impact resistance and higher hardness, consistent in the last hundred years by human as the impact grinding rock material and a large amount of the use.
Be embedded in hard alloy spherical-teeth and make various drill bits on the metallic steel body, when the impact grinding soft rock, show higher efficient and long life-span, can satisfy the requirement of detritus in the engineering construction, but when running into the bigger rock of hardness, although hard alloy spherical-teeth also has than higher hardness, the sintered carbide ball odontotripsis is very fast, it is short to show as the life-span, efficient is low, hard alloy spherical-teeth has just had a strong impact on the result of use of the drill bit of making like this, in hard formations such as a lot of granites, utilize impact detritus bit life that hard alloy spherical-teeth makes less than 10 meters, this has not only influenced the engineering construction progress, also caused very big material consumption, and the main raw material(s) of producing hard alloy spherical-teeth is a WC-Co, nickel etc., these all are non-renewable natural resources, application life, extremely short hard alloy spherical-teeth brought the huge wasting of resources, thereby be necessary to find and invent a kind of novel ball tooth that improves the impact grinding rock, the life-span that the hard alloy spherical-teeth detritus that is beneficial to take on a new look exists is short, inefficient drawback.
Summary of the invention
Technical problem to be solved by this invention provides a kind of shock resistance and anti-wear energy is high, is suitable for making the compound detritus ball of the polycrystalline diamond-carbide alloy tooth that uses on the down-the-hold drill bit detritus instrument.
In order to solve the problems of the technologies described above, the compound detritus ball of polycrystalline diamond-carbide alloy provided by the invention tooth comprises the hard alloy spherical-teeth main body, is provided with a polycrystalline diamond in described hard alloy spherical-teeth main body at least.
Described polycrystalline diamond is the polycrystalline diamond short cylindrical, is located in the hole on the described hard alloy spherical-teeth main body, and the length of described polycrystalline diamond short cylindrical and diameter dimension are 1～50mm * φ 1～φ 30mm.
The hole of used hard alloy spherical-teeth main body is preformed in the production of described hard alloy spherical-teeth main body, or obtains by the technology of laser boring.
Described polycrystalline diamond short cylindrical is inlayed by the mode of interference fit in the hole that is fixed on described hard alloy spherical-teeth main body, and the magnitude of interference that described hole and described polycrystalline diamond short cylindrical cooperate is controlled at 0.01～0.05mm.
Described polycrystalline diamond short cylindrical is fixed in the hole of hard alloy spherical-teeth main body by the mode of soldering, and the method for welding of employing is silver soldering, brazing or Laser Welding.
Compare with existing hard alloy spherical-teeth, the compound detritus ball of polycrystalline diamond-carbide alloy provided by the invention tooth, owing to adopted carbide alloy and the multiple main material of polycrystalline diamond, the high impact resistance that has kept carbide alloy to have at aspect of performance, simultaneously because diamond is the hardest mineral of finding and being used in a large number in the world at present, thereby polycrystalline diamond has high anti-wear performance, thereby the compound detritus ball of polycrystalline diamond-carbide alloy tooth is under the prerequisite that keeps existing hard alloy spherical-teeth high impact resistance, anti-wear performance also is higher than carbide alloy far away, have high anti-wear performance, guarantee that the compound detritus ball of polycrystalline diamond-carbide alloy tooth has very high service efficiency and very long application life.The present invention is simple in structure, and production and processing is convenient, and ball tooth shock resistance and anti-wear energy are high, are suitable for making on the first-class detritus instrument of hidden hole drilling and use.
