Abstract
The present invention discloses a hard alloy fragmented drill bit, belonging to a geologic drilling bit for drilling various stratums. It is characterized by that the block hard alloy can be crushed into small granules with 0.1-3.5 mm, and then the small granules can be fixed on the working layer of drilling bit steel body by means of the methods of electroplating, hot-pressing and welding, etc. so as to form the cutting layer of said drilling bit.
Description
Technical field
The present invention relates to a kind of geology drill bit, especially a kind of hard alloy crumbed drilling bit.Be applicable to the boring on all kinds of stratum in geological prospecting and each engineering field.
Background technology
The geology drill bit of prior art, form by steel body and the monoblock carbide alloy working lining that is embedded on the steel body, method boring with rotation, impact grinding rock, the material that working lining adopted is outside the artificial superhard materials such as diamond, composite sheet, the formed body that also has the various type shapes of carbide alloy, adopt the whole bag of tricks to be fixed on the drill steel body, because carbide alloy is hard and crisp, easily burst apart after being impacted in creeping into, the contact surface of cutting edge and rock is big, cutting edge is few, is difficult to improve drilling speed and rock stratum rank.
Summary of the invention
The objective of the invention is to provide at the problems referred to above a kind of be difficult for bursting apart can effectively improve rate of penetration and other hard alloy crumbed drilling bit of rock stratum level.
The technical solution adopted for the present invention to solve the technical problems is: the fine particle of the hard metal tip of block being smashed into to pieces the 0.1-3.5 millimeter; again these particles are adopted methods such as plating, hot pressing, welding to be fixed on the working lining of drill steel body; form from the cutting lay that grinds sword; hard and sharp granule; be easy to cut rock; granule has metal coatings such as plating, hot pressing, welding outward, from grind sword can not be subjected to impact force after and burst apart.
The invention has the beneficial effects as follows: be easy to cut rock, be difficult for bursting apart, the YG class can be contained gold and bring up to YT or the use of higher class alloy, improve drilling speed and bit life, and can mix use with diamond, and carry out performance complement, improve the abrasion resistance and the compliance of diamond bit.Diamond grade be can improve, and drilling speed and bit life improved.
The invention will be further described below in conjunction with accompanying drawing for description of drawings.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of another embodiment of the present invention.
Among the figure: 1 is the drill steel body, and 2 is that hard alloy particle and admixture diamond dust .3 are working lining.
The specific embodiment is referring to accompanying drawing, the present invention is made up of drill steel body (1) and working lining (3), it is characterized in that: described working lining (3) is that the hard alloy particle of 0.1-3.5 millimeter and diamond dust (2) adopt methods such as plating, hot pressing, welding to be fixed on the drill steel body (1) by particle.In the embodiments of the invention, hard alloy particle (2) is with the broken acquisition of bulk carbide alloy.
Except that working lining shown in Figure 1 (3) is positioned at end face (axially) position of steel body (1), in the another embodiment of the present invention, as shown in Figure 2, working lining (3) is positioned at the position, side (radially) of steel body (1), the brill of Fig. 2 structure is commonly referred to as reamer or reamer.
Claims (2)
1, a kind of hard alloy crumbed drilling bit, be made up of drill steel body (1) and working lining (3), it is characterized in that: described working lining (3) is that the hard alloy particle of 0.1-3 millimeter and diamond dust (2) adopt methods such as plating, hot pressing, welding to be fixed on the drill steel body (1) by particle diameter.
2, carbide drill according to claim 1 is characterized in that: described working lining (3) can be positioned at the end face or the side of steel body (1).
