Abstract
The present invention directly is soldered on the supporter of hard material with the diamond glomerocryst of difformity and thickness, makes cover novel artificial dimond synneusis a---hard material composite gear.This class composite teeth can be used as makes cutting edge, is used on the various boring tools such as oil, coal, mine, geology.This class composite teeth can be according to the lithology design tooth profile.With the drill bit that they are made, self-sharpening is good, can wear into Reasonable Shape certainly, drilling speed and bit life height, and the heat resistance height can be made drill bit with existing diamond bit sintering process.
Description
The present invention relates to a novel artificial dimond synneusis-hard material composite gear that cover is novel, structure is unique.This class NEW TYPE OF COMPOSITE tooth can be used as cutting edge, is used on all kinds of boring tools such as oil, coal, mine and geology.
Diamond glomerocryst-hard alloy complex sheet tooth that GE now produces is with method for welding diamond glomerocryst-hard alloy complex sheet to be welded on the inclined-plane of hard alloy columnar.The shortcoming of this composite sheet tooth is that shape is single, and is poor to the adaptive capacity that the lithology soft or hard changes, along with the wearing and tearing of tooth, cutting edge constantly broadens, the contact surface of cutting edge and rock also increases thereupon, causes drilling speed to descend, and can cause quick-fried sword because of the cutting edge blunt when especially creeping into harder stratum.In addition, in this composite sheet tooth, because the heat resisting temperature of diamond glomerocryst-hard alloy complex sheet itself is lower, therefore this composite sheet tooth can only anti-temperature below 700 ℃.This composite sheet tooth also just can not directly adopt the higher diamond sintering technology of temperature to be mounted on the cast tungsten carbide alloy bit body, and can only with low-temperature brazing filler metal be soldered to it on bit body or with interference fit with in its drill bit body opening of colding pressing.
Task of the present invention is the novel artificial dimond synneusis-hard material composite gear that a cover rock cutting efficient height will be provided, adapt to lithology face width, life-span length.This class tooth can be widely used on oil, coal, mine and the geological drilling tools.Novel artificial dimond synneusis-hard material composite gear of the present invention has following advantage:
It is can select the glomerocryst thin slice of one or more pieces difformities, different-thickness and different abrasion resistancies directly to be soldered on the hard material supporter according to lithological characteristic to make that one class is arranged in the composite teeth of the present invention.The material of hard material supporter and shape also can be selected for use according to lithological characteristic, the optional carbide alloy of material, steel, cast tungsten carbide-dimond synneusis and copper alloy sintered body etc. that it is commonly used.Therefore, this class composite teeth of the present invention just has the characteristics of gradient hard material, can constantly produce rational sharping by oneself affect in the rock cutting process, and can remain sharper cutting edge;
Composite teeth shape of the present invention is various, and this not only can select the cutting edge of Reasonable Shape according to lithological characteristic, and can be beneficial to the raising drilling speed constantly from wearing into rational shape in working angles.
Composite teeth heat resistance height of the present invention can anti-about 1200 ℃ high temperature in protective atmosphere, and decapacitation is satisfied outside the manufacturing process of existing composite teeth drill bit, can also directly make drill bit with general diamond bit high-sintering process.

The concrete structure of novel artificial dimond synneusis-hard material composite gear of the present invention can be illustrated more clearly in accompanying drawing:
Fig. 1-the 4th, several examples of first type of novel artificial dimond synneusis-hard material composite gear of the present invention.Its design feature be with the diamond synneusis sheet (1) of difformity and thickness directly soldering on hard material supporter (2).But the sintered body of material carbide alloy, steel, cast tungsten carbide-dimond synneusis and the copper alloy of hard material supporter etc.But its shape cylinder, cuboid, oval cylinder etc.This class composite teeth has advantage simple in structure, easy to manufacture.
Fig. 5-the 8th, several examples of second type of novel artificial dimond synneusis-hard material composite gear of the present invention.Its design feature be synneusis sheet soldering that difform two or more abrasion resistance is different together, during soldering, should arrange by glomerocryst abrasion resistance height order.And then will
The one side that multilayer polycrystal (1) welded together wears no resistance is soldered on the inclined-plane of hard material supporter (2).The material of hard material supporter and shape and novel artificial dimond synneusis-hard material composite gear of the present invention first type identical.This multilayer glomerocryst composite teeth because multilayer polycrystal and hard material have been formed the wear-resistant gradient material, can produce rational sharping by oneself affect in drilling process.This class composite teeth, the combination that can select the gradient material according to lithological characteristic for use, with this regulate composite teeth from sharp degree, make it reach optimum efficiency.
