Description

Novel impregnated bit

Technical field

The utility model relates to the technical field of a kind of geological drilling with drill bit, relates in particular to a kind of novel impregnated bit.

Background technology

At present in geological prospecting, bore in the exploitation and adopt impregnated bit to creep into when meeting extremely hard formation usually, impregnated bit is because himself to have a life-span long, the drilling depth height, advantage such as safety is good can shorten exploitation cycle and drilling cost, is favored.

In the prior art, the impregnated bit principal mode is divided into whole pressureless sintering impregnated bit, the electroforming impregnated bit, and braze welding type impregnated bit etc., the hardness of these drill bits is very high, but still has the shortcoming that the production cycle is long, cost is high.

And, no matter the impregnated bit that uses at present is to adopt electroforming process, or soldering processes behind the sintering, exist the production cycle long, receive restrictions such as equipment mould, make difficulty when bit size is bigger.

For this reason, the designer of the utility model is because above-mentioned defective through concentrating on studies and designing, comprehensively is engaged in for a long time the experience and the achievement of related industry for many years, and research and design goes out a kind of novel impregnated bit, to overcome above-mentioned defective.

Summary of the invention

The purpose of the utility model is to provide a kind of novel impregnated bit, and it is simple in structure, and is easy to use, and with short production cycle, and the drill bit security performance is high, and the impregnated bit size is wider, and low cost of manufacture also adapts to simultaneously and makes large scale high-performance impregnated bit.

For realizing above-mentioned purpose, the utility model discloses a kind of novel impregnated bit, this drill bit comprises drill body 1, water spray eye 2, wing 3, attachment weld 4 and composite sheet cutting teeth 8, it is characterized in that:

Wing 3 is spaced apart around drill body 1, on the drill body 1 that water spray eye 2 is arranged between the wing 3, can be provided with cutting teeth 8 on the cutting edge of wing 3, and wing 3 is connected through attachment weld 4 with drill body 1.

Wherein, wing 3 is made up of steel core 5 and carcass 6.

Wherein, impregnated or table studs with high-abrasive material 7 in the carcass 6.

Wherein, described high-abrasive material 7 is superhard wear alloy or diamond or natural diamond.

Wherein, wing 3 is provided with 1-25 composite sheet cutting teeth 8.

Wherein, 3-100 wing 3 is set on the drill body.

Through said structure, the novel impregnated bit of the utility model has following technique effect:

1, the wing split is made, and can shorten the process-cycle, reduces production costs, and can enlarge bit size simultaneously;

2, adopt welding between wing and the drill body, wing heart portion material is steel, drill bit work wing good toughness, and the antifatigue degree is high, and the drill bit security performance is higher;

3, the high-abrasive material on the wing is through electroforming, hot pressed sintering, methods such as pressureless sintering; High-abrasive material is plated in carcass, can be divided into impregnated or mode such as table edge etc., the manufacturing process range of choice is wider; The drill bit adaptive surface is wider, and a plurality of wings are produced in batches simultaneously simultaneously, and the process-cycle is short; Reduced the volume of carcass, the drill produced cost can reduce.

The detailed content of the utility model can through after explanation and the institute's accompanying drawing stated obtain.

Description of drawings

Fig. 1 has shown the schematic perspective view of the novel impregnated bit of the utility model.

Fig. 2 has shown the schematic perspective view of wing of the novel impregnated bit of the utility model.

Fig. 3 has shown the sectional view of A-A direction among Fig. 2.

The specific embodiment

Referring to Fig. 1, shown the schematic perspective view of the novel impregnated bit of the utility model, this drill bit mainly comprises: drill body .1, water spray eye 2, wing 3, attachment weld 4 and composite sheet cutting teeth 8 etc.

Wherein, drill body 1 is cylindric, and wing 3 is spaced apart around drill body 1; Preferred drill body 1 is provided with 3-100 wing 3, and the cutting edge of each wing 3 is provided with at least one composite sheet cutting teeth 8, and preferably each wing 3 has 1-25 composite sheet cutting teeth 8; Wherein, The diameter range of cutting teeth 8 is Φ 5.0-Φ 40.0mm, and a plurality of water spray eyes 2 are arranged on the drill body 1 between the wing 3, and each wing 3 is connected with drill body 1 through attachment weld 4.Its difference is in the said structure that when drill body 1 is made with wing 3 be split, forms a drill bit thereby be welded as a whole drill bodies that process 1 and wing 3 through weld seam 4.

Referring to Fig. 2 and Fig. 3, shown the wing 3 of the novel impregnated bit of the utility model, this wing 3 comprises steel core 5 and carcass 6; Steel core 5 is positioned at the side near drill body 1, and carcass 6 then is positioned at opposite side, wherein; Steel core 5 is provided with convexity; Carcass 6 makes itself and steel core become one through same process means such as sintering or electroforming, wherein, plates or show to stud with high-abrasive material 7 in the carcass 6; High-abrasive material 7 is any mixing of superhard wear alloy or diamond or natural diamond or above-mentioned three kinds of materials, and composite sheet cutting teeth 8 is welded in the tooth cave on the carcass 6 of wing 3.
