Abstract
The invention provides a labial surface shape of a diamond-impregnated drill. The diamond-impregnated drill belongs to diamond product in the power metallurgy industry. The ''labial surface shape of the diamond-impregnated drill'' can change the service life and the efficiency of the diamond-impregnated drill during rock drilling. The ''labial surface shape of the diamond-impregnated drill'' provided by the invention solves the problems of high efficiency but short service life of a ''saw-tooth'' drill and long service life but low efficiency of a ''flat-bottom'' drill. According to the labial surface provided by the invention, the drilling efficiency of the drill is always higher than that of the ''saw-tooth'' drill, and the service life of the bill is always longer than that of the ''flat-bottom'' drill no matter what kinds of rock stratums are drilled.
Description
Technical field:
Diamond composition in the powder metallurgy field
Background technology:
The diamond impregnated bit development has history decades so far, and its labial surface shape (working lining shape) also has a variety of, and the sort of shape is best also not to be confirmed in practice but also derive theoretically so far.Total common recognition in the industry is: " skidding " rock stratum is with " sawtooth " type end labial surface and the bigger drill bit of rock contact surface, and the characteristics of this type of drill bit are: efficient is high, and the life-span is low.Rock is not very hard to creep into the rock stratum easily with flat or circular arc and the less drill bit of rock contact surface, and the characteristics of this type of drill bit are: the life-span is long, and efficient is low.
Summary of the invention:
Broken traditional design concept, the labial surface shape of the diamond impregnated bit that under the guidance of basic theory, designs is confirmed in practice.Characteristics are: no matter in what rock stratum creep into, what the drilling efficiency of drill bit can be than " sawtooth " type is low, and what the life-span can be than " not flat " type yet simultaneously is little.
Description of drawings:
Figure one drill bit labial surface (working lining part) is a hollow.
Diamond concentration in the middle of the figure two drill bit working linings is lower than the concentration on both sides.
The specific embodiment:
It has adopted hollow shape.Shown in the figure one.For the convenience of making is inserted the less material of wear resistance ratio (wear and tear more little think near hollow is unreasonable more) in the middle of also can adopting.If the diamond concentration in the middle of the working lining is lower than the concentration on both sides, shown in the figure two, also can reach certain effect (wear resistance ratio in the middle of the working lining also can be smaller than the wear resistance ratio on both sides like this).
Claims (1)
1. the labial surface shape of diamond impregnated bit can determine the life-span and the efficient of drill bit itself." the labial surface shape of diamond impregnated bit " of the present invention 1. adopted hollow shape, has been empty in the middle of the labial surface of diamond impregnated bit (working lining) both.2. use graphite for the convenience made and for carcass strength in the middle of considering also can adopt, the smaller material filling of wear resistance ratios such as iron block is (wear and tear more little think near hollow is unreasonable more) wherein.3. if the diamond concentration in the middle of the working lining is than the low certain effect (wear resistance ratio in the middle of the working lining can be littler than the wear resistance ratio on both sides like this) that also can reach of concentration on both sides.
