Abstract
The utility model provides a kind of diamond bit to drill and ream for composite material, including cutter hub, and one end of cutter hub is drill bit, several blades are welded on drill bit, wherein, the one third Zhou Ren positioned at blade front end is cutting edge, and 2/3rds weeks swords positioned at blade rear end are cylindrical edge band.The beneficial effects of the utility model are: improving the processing quality of drilling, while improving drilling life of bit.
Description
Technical field
The utility model patent is related to machine-building metal cutting process field, is mainly used in titanium alloy and carbon fiber is folded
High efficiency, the high quality of layer material drill and ream into hole machined.
Background technique
Titanium alloy and carbon fibre laminates material are the typical difficult-to-machine materials of modern Aviation manufacture field, in its hole machined
In the process, common high-speed steel or carbide drill carry out drilling at present.To improve hole machined quality and the requirement of hole internal diameter precision,
1/3 is cutting edge (not having Circular Nose Cutting Edge band) before PCD blade Zhou Ren, and the Circular Nose Cutting Edge band of rear 2/3 a length of width consistent with alloy cutter hub is whole
Outer diameter is equal before and after section PCD blade Zhou Ren.
Since two kinds of material mechanical processing performance differences of titanium alloy and carbon fiber are very big, when carrying out drilling using conventional bit
The cutting ability of two kinds of materials cannot be combined.When machining titanium alloy material, cutting edge requires have enough intensity, can bear
Biggish cutting force；And when processing carbon fibre material, cutting edge requires have enough hardness, has very high wearability and sharp
Property, when preceding common high-speed steel or carbide drill drilling titanium alloy and carbon fibre laminates material, tool wear quickly, seriously
Tipping, and carbon fiber is easy to produce splitting and fiber burr in drilling process mesoporous oral pore wall, seriously affects hole machined matter
Amount and dimensional accuracy, subsequent also device to hole to be needed to be finished, process is more, and working hour is long.
Summary of the invention
In order to overcome the shortcomings of the prior art, the utility model patent provides a kind of existing sufficient intensity foot again
The diamond bit of enough hardness meets titanium alloy and carbon to take into account the titanium alloy cutting ability different from two kinds of materials of carbon fiber
The requirement of superimposed fiber material drilling performance, improves hole machined finish precision quality and cutter life, by drilling and finishing
Work fraising is primary to be completed, and processing efficiency is improved.
A kind of diamond bit to drill and ream for composite material, including cutter hub, one end of cutter hub are drill bit, are welded on drill bit
Several blades, wherein the one third Zhou Ren positioned at blade front end is cutting edge, and 2/3rds weeks swords positioned at blade rear end are circle
Column land.
Further, cutter hub is cemented carbide material, and blade is ultra-hard material poly-crystal diamond.
Further, the apex point center of drill bit is cemented carbide material.
Further, drill bit main cutting edge periphery and end cutting edge welding polycrystalline diamond (PCD) blade.
Further, side set distributed architecture is presented in the multiple blade.
The beneficial effects of the utility model are: in processing and when titanium alloy and carbon fibre laminates material, improve drilling plus
Working medium amount improves drilling life of bit；Main cutting edge blade weld seam in drilling process is eliminated to adversely affect to drilling bring；
Cutting edge cutting edge cutting hole oral pore wall burr, cylindrical edge band part finishing fraising, guarantees hole wall finish and aperture precision, once
It completes drilling to finish with fraising, improves processing efficiency and processing quality.
Detailed description of the invention
With reference to the accompanying drawing, by the way that specific embodiment of the present utility model is described in detail, the utility model will be made
Technical solution and other beneficial effects are apparent.
Fig. 1 is the drill bit structure schematic diagram of the utility model embodiment.
Fig. 2 is the left view of the utility model drill bit.
Fig. 3 is another structural schematic diagram of drill bit of the utility model embodiment.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of diamond bit 10 to drill and ream for composite material, including cutter hub 20, one end of cutter hub are drill bit 30, drill bit
Upper several blades 40 of welding.
In the utility model embodiment, cutter hub 20 is cemented carbide material, and blade 40 is ultra-hard material poly-crystal diamond
(PCD).Using hard alloy cutter hub welding polycrystalline diamond (PCD) blade design structure and process scheme, titanium conjunction is taken into account
The gold cutting ability different from two kinds of materials of carbon fiber, meets titanium alloy and carbon fibre laminates material drilling performance demand.
The apex point center 50 of drill bit is cemented carbide material, and in drill bit drilling, especially apex point center is squeezed in low speed
In workpiece fabrication, guarantee has enough intensity, will not shift to an earlier date tipping and drill bit is caused to fail.
43 periphery of main cutting edge of drill bit and 44 welding polycrystalline diamond of end cutting edge (PCD) blade, so that drill bit is in height
Still there are very high hardness and wearability under fast cutting state, so that titanium alloy and carbon fibre laminates material hole machined quality are promoted,
Improve drilling life of bit.
Further, the one third positioned at blade front end of blade 40 is cutting edge 41, is used for hole in boring procedure
The carbon fiber burr splitting of entrance, hole wall, hole exits machines away, and is cylindrical edge band 42 positioned at the rear end of blade 2/3rds, uses
It is acted in fraising, guarantees hole wall finish and precision size.
The technical solution of the utility model using hard alloy cutter hub welding polycrystalline diamond (PCD) blade design structure and
Process scheme, not only ensure that in drilling process, and drill bit is integrated with enough rigidity, and apex point center (chisel edge) is squeezed in low speed
There is enough intensity when pressing workpiece, tipping will not be shifted to an earlier date and drill bit is caused to fail；Cut drill bit main cutting edge periphery and pair
Cut sword still has very high hardness and wearability under high-speed cutting state, adds to promote titanium alloy with carbon fibre laminates material hole
Working medium amount improves drilling life of bit.
Secondly, eliminating drilling using two panels polycrystalline diamond (PCD) blade side set (length is different) distribution design structure
Main cutting edge blade weld seam is adversely affected to drilling bring in the process.
Finally, all sword cutting edges of blade are divided into two sections of cutting edge structure designs, cutting edge cutting edge cutting hole oral pore wall burr, cylinder
The finishing fraising of land part, guarantees hole wall finish and aperture precision, and primary completion drilling is processed with fraising.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
