PCD spiral bit structural design is reasonable, realizes carrying out efficient drilling operation to the work piece through cutting portion and tip portion, and in drilling process, the cutting portion of one section PCD material is minimum with metal material's compatibility, is difficult for gluing the bits phenomenon because of drilling produces, and the size precision and the smooth finish preferred in aperture are just processed in difficult wearing and tearing.
Description
Technical field
This utility model relates to a kind of drill bit, particularly relates to a kind of PCD augers.
Background technology
In the last few years, along with the development of science and technology, machinery manufacturing industry is also more and more higher to the requirement of machining accuracy,
Drill bit is as a kind of machining Common Use Tools, and its structure not only decides the intensity of self, service life,
Further determine error size and the precision height getting out workpiece hole.
At space flight, aviation, military project, automotive field, use composite in a large number, the size to processing aperture
Precision and smoothness requirements are higher, require the technology of process tool itself simultaneously and service life is more and more higher,
Although the processing of existing carbide drill can meet means suitable, but very fast because of abrasion in the course of processing,
The aperture size concordance causing product is the best, and fraction defective is higher.Further, since existing drill bit structure sets
Count unreasonable, affect self intensity and service life.
Utility model content
Based on this, it is necessary to for the problems referred to above, it is provided that a kind of reasonable in design, the most easy to wear and processing
The dimensional accuracy in aperture and fineness preferably PCD augers.
A kind of PCD augers, the cutting portion including: clamping part, being connected to described clamping part one end, with
And convexedly stretch in the pointed nose of described cutting portion；Described clamping part, described cutting portion and described pointed nose have
Same center of rotation axle；Spiral type chip area is offered around center of rotation axle, near institute on described cutting portion
The apical margin of the described cutting portion stating pointed nose has cutting face；Described pointed nose is pyramidal structure, described
Offering V-groove on the described cutting portion of pointed nose and close described pointed nose, described V-groove is from described
The directional smoothing transition of the top of pointed nose extremely described spiral type chip area；Described pointed nose and connection are described
One section of cutting portion of pointed nose is PCD material, the cutting portion of this section of PCD material and residue section cutting portion weldering
Connect.
Above-mentioned PCD spiral bit structure is reasonable in design, realizes workpiece is carried out height by cutting portion and pointed nose
The drilling operation of effect, in boring procedure, the cutting portion of one section of PCD material and the affinity pole of metal material
Little, it is difficult to because boring produces viscous bits phenomenon, the most easy to wear and dimensional accuracy in processing aperture and fineness are preferable.
Wherein in an embodiment, the number of described spiral type chip area is two, two spiral type chip removals
Groove is turned round around setting.
Wherein in an embodiment, section cutting portion is one-body molded is connected with residue for described clamping part.
Wherein in an embodiment, described clamping part removably connects with residue section cutting portion.
Wherein in an embodiment, the outer surface of described cutting portion has titanium carbonitride layer.
Wherein in an embodiment, the outer surface of described cutting portion has aluminium nitride titanium layer.
Wherein in an embodiment, the outer surface of described clamping part has thermal dispersant coatings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the PCD augers of this utility model one preferred embodiment.
Detailed description of the invention
For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is carried out more comprehensively
Description.Accompanying drawing gives preferred embodiment of the present utility model.But, this utility model can be to be permitted
The most different forms realizes, however it is not limited to embodiment described herein.On the contrary, provide these to implement
The purpose of example is to make the understanding to disclosure of the present utility model more thorough comprehensively.
As it is shown in figure 1, the PCD of this utility model one preferred embodiment (Polycrystalline Diamond,
Polycrystalline diamond) augers 10, including: clamping part 11, the cutting portion that is connected to clamping part 11 one end
12 and convexedly stretch in the pointed nose 13 of cutting portion 12.Clamping part 11, cutting portion 12 and pointed nose 13
There is same center of rotation axle 20.Spiral type chip area is offered around center of rotation axle 20 on cutting portion 12
121, the apical margin near the cutting portion 12 of pointed nose 13 has cutting face 122.Pointed nose 13 in pyramidal structure,
V-groove 131, V-groove 131 is offered on pointed nose 13 and on the cutting portion 12 of pointed nose 13
From the top of pointed nose 13 to the directional smoothing transition of spiral type chip area 121.Pointed nose 13 and connection
One section of cutting portion of pointed nose 13 is PCD (Polycrystalline Diamond, polycrystalline diamond) material,
The cutting portion of this section of PCD material welds with residue section cutting portion.In order to express easily, pointed nose will be connected
The cutting portion of one section of PCD material of 13 is defined as the first cutting portion 14, by weld with the first cutting portion 14
Residue section cutting portion is defined as the second cutting portion 15.
Above-mentioned PCD augers 10 reasonable in design, it is right to be realized by cutting portion 12 and pointed nose 13
Workpiece carries out efficient drilling operation, in boring procedure, and the cutting portion of one section of PCD material and metal material
Affinity minimum, be difficult to produce viscous bits phenomenon because of boring, the most easy to wear and dimensional accuracy in processing aperture and
Fineness is preferable.
