Abstract
The utility model relates to a novel spherical tooth based on hard alloy, relating to a structure of hard alloy spherical tooth. The novel spherical tooth consists of a hard alloy spherical head and a steel base, wherein the top of the hard alloy spherical head is a semispherical head (1), a blind hole (2) is arranged at the bottom of a cylinder body of the lower part of the hard alloy spherical head, and an inner thread is arranged on the inner surface of the blind hole (2); a screw rod (3) is arranged at the upper part of the steel base, a cylindrical base (4) is arranged at the lower part of the steel base, and the diameter of the screw rod (3) is smaller than the diameter of the cylindrical base (4); and the screw rod (3) is matched with the inner thread of the blind hole (2), and a step at the circumference of the upper part of the cylindrical base (4) is supported on the bottom surface of the hard alloy spherical head. The utility model relates to the hard alloy spherical tooth for a mine, an oil field and a drill head for developing and drilling mountains, wherein a raw material is 100% of highly-qualified raw tungsten carbide powder and is machined by a low-pressure sintering process. The novel spherical tooth based on the hard alloy disclosed by the utility model can be applied to a hard alloy drill bit, and has the advantages of low cost, high hardness, convenience in machining and manufacture, and convenience in device mounting.
Description
Technical field
a kind of novel ball tooth based on carbide alloy.
Background technology
The hardness of carbide alloy is high, and abrasion resistance is good, and hard alloy spherical-teeth mainly is used on the drill bit of the probing of cutting into a mountain.
Existing hard alloy spherical-teeth is mainly processed by carbide alloy, exists to be not easy to the shortcoming of processing and installing.
Summary of the invention
The utility model provides a kind of novel ball tooth based on carbide alloy, and the utility model has solved existing hard alloy spherical-teeth and has been not easy to the problem of processing and installing.
For addressing the above problem, the utility model adopts following technical scheme: a kind of novel ball tooth based on carbide alloy is made up of carbide alloy bulb and steel base;
Said sintered carbide ball head is the spherical ballhead 1 of semicircle, and there is blind hole 2 bottom surface of carbide alloy bulb lower cylindrical body, and blind hole 2 inner surfaces have internal thread;
Steel base top is that screw rod 3, bottom are cylindrical seat 4, and the diameter of screw rod 3 is less than the diameter of cylindrical seat 4;
The screw-internal thread fit of said screw rod 3 and blind hole 2, the step of cylindrical seat 4 upper periphery is supported on the carbide alloy bulb bottom surface.
The utility model be used for mine, oil field, the drill bit of the probing of cutting into a mountain use hard alloy spherical-teeth, raw material 100% is the primary tungsten carbide powder of high-quality, employing low pressure sintering technology is processed.The utility model can be applicable on the carbide drill.It is low to the utlity model has cost, and hardness is high, is convenient to processing and manufacturing, is convenient to the advantage that equipment is installed.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: ballhead 1, blind hole 2, screw rod 3, cylindrical seat 4.
The specific embodiment
With illustrated embodiments the utility model is done detailed explanation below.
As shown in Figure 1, a kind of novel ball tooth based on carbide alloy is made up of carbide alloy bulb and steel base;
Said sintered carbide ball head is the spherical ballhead 1 of semicircle, and there is blind hole 2 bottom surface of carbide alloy bulb lower cylindrical body, and blind hole 2 inner surfaces have internal thread;
Steel base top is that screw rod 3, bottom are cylindrical seat 4, and the diameter of screw rod 3 is less than the diameter of cylindrical seat 4;
The screw-internal thread fit of said screw rod 3 and blind hole 2, the step of cylindrical seat 4 upper periphery is supported on the carbide alloy bulb bottom surface.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
