Description
Technical field
This utility model relates to drilling technique field, particularly relates to a kind of hard alloy spherical-teeth.
Background technology
At present both at home and abroad center three gear wheel, engineering and the colliery etc. of oil drilling are all hard alloy spherical-teeths without the boring insert cutter employing of core, its using method is by drilling blind hole on hobboing cutter body, and this hobboing cutter body is heated to uniform temperature, after button less grinder for grinding freezing, with forcing press, button is pressed into the blind hole on hobboing cutter body.This method there is problems in that
1, part button is had to be embedded in hobboing cutter body, it is impossible to cut rock stratum and slattern；
2 it cannot be guaranteed that each button can fasten, and button obscission easily occurs；
3, complex process, cost is high.
Sintered carbide ball teeth drill bit is a kind of existing impact grinding rock or the instrument digging soil layer, there is for the down-the-hold drill bit that other metal materials are made certain impact resistance and higher hardness, used in a large number as impact grinding rock or the industrial tooth of cutting soil layer by industry the most always.
Sintered carbide ball teeth drill bit is made up of with the multiple hard alloy spherical-teeths on drill main body drill main body and installation, when encountering the bigger rock of hardness, although hard alloy spherical-teeth also has the hardness that comparison is high, but the bulb of hard alloy spherical-teeth weares and teares the most quickly, utilize the impact detritus bit life that hard alloy spherical-teeth is made less than 10 meters, show as the life-span is short, efficiency is low, had a strong impact on fractured rock effect and engineering construction progress.
Summary of the invention
The purpose of this utility model embodiment is to provide a kind of hard alloy spherical-teeth, it is possible to solve the problem that existing hard alloy spherical-teeth anti-wear performance is poor, service efficiency is low and service life is low.
This utility model solves the problems referred to above by techniques below means:
A kind of hard alloy spherical-teeth, including integrated tooth head and body, described tooth head is positioned at described body upper part, and described tooth head is provided with crown.
Further, described body is the cylinder of hollow, and described tooth head is the cone of hollow, and described cylindrical radius is equal with the radius of described cone.
Further, described body is the cylinder of hollow, and described tooth head is the cone of hollow, and described cylindrical radius, less than the radius of described cone, is connected by the first connector between described cylinder with described cone.
Further, described first connector is round platform.
Further, described first connector is annulus.
Further, described body is the cylinder of hollow, and described tooth head is the cone of hollow, and described cylindrical radius, more than the radius of described cone, is connected by the second connector between described cylinder with described cone.
Further, described second connector is round platform.
Further, described second connector is round platform.
Further, described crown surface is provided with scuff-resistant coating.
Further, described scuff-resistant coating is provided with the anti-abrasive particle of protrusion.
Hard alloy spherical-teeth of the present utility model, compared with prior art, is connected the cylindrical body of hollow with the circular cone tooth head of hollow, and arranges crown on tooth head, at crown surface configuration scuff-resistant coating.Improve the abrasionproof performance of tooth head, tooth head is the most easy to wear, improves service efficiency and the service life of hard alloy spherical-teeth.Further, crown scuff-resistant coating is provided with the anti-abrasive particle of protrusion, can be as the bolster of wear and shock-resistant, it is ensured that the uniform force of tooth head, in order to extend the service life of hard alloy spherical-teeth, reduce construction cost.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Seeing Fig. 1, be the structural representation of a kind of hard alloy spherical-teeth that this utility model embodiment provides, described hard alloy spherical-teeth includes that integrated tooth head 1 and body 2, described tooth head 1 are positioned at described body 2 top, and described tooth head 1 top is provided with crown 11.
Described crown 11 surface is provided with scuff-resistant coating (not shown).Described scuff-resistant coating is provided with the anti-abrasive particle 12 of protrusion.
As a better embodiment of technique scheme, such as Fig. 1, described body 2 is the cylinder of hollow, described tooth head 1 is the cone of hollow, described cylindrical radius is equal with the radius of described cone, and so, body 2 can be to be directly connected by integrated mode with tooth head 1.
A better embodiment as technique scheme, such as Fig. 2, described body 2 is the cylinder of hollow, described tooth head 1 is the cone of hollow, described cylindrical radius, less than the radius of described cone, is connected in integrated mode by the first connector 3 between described cylinder with described cone.Wherein, described first connector 3 can be round platform, and the upper bottom surface radius of round platform is identical with cylindrical radius, and the bottom surface radius of round platform is identical with the radius of cone.Described first connector 3 can also be annulus, and the inside radius of annulus is identical with cylindrical radius, and the outer radius of annulus is identical with the radius of cone.
A better embodiment as technique scheme, such as Fig. 3, described body 2 is the cylinder of hollow, described tooth head 1 is the cone of hollow, described cylindrical radius, more than the radius of described cone, is connected in integrated mode by the second connector 4 between described cylinder with described cone.Wherein, described second connector 4 can be round platform, and the upper bottom surface radius of round platform is identical with the radius of cone, and the bottom surface radius of round platform is identical with cylindrical radius.Described second connector 4 can also be annulus, and the inside radius of annulus is identical with the radius of cone, and the outer radius of annulus is identical with cylindrical radius.
Hard alloy spherical-teeth of the present utility model, compared with prior art, is connected the cylindrical body of hollow with the circular cone tooth head of hollow, and arranges crown on tooth head, at crown surface configuration scuff-resistant coating.Improve the abrasionproof performance of tooth head, tooth head is the most easy to wear, improves service efficiency and the service life of hard alloy spherical-teeth.Further, crown scuff-resistant coating is provided with the anti-abrasive particle of protrusion, can be as the bolster of wear and shock-resistant, it is ensured that the uniform force of tooth head, in order to extend the service life of hard alloy spherical-teeth, reduce construction cost.
