In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that,
Accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art
From the point of view of, on the premise of not paying creative work, it is also possible to obtain the attached of other according to these accompanying drawings
Figure.
Fig. 1 is the structural representation of a kind of detailed description of the invention of cutting steel wire provided by the present invention；
Wherein: 1-cutting main body, the outer wrapping wire of 2-.
Detailed description of the invention
The core of the present invention is to provide a kind of cutting steel wire, and this cutting steel wire can significantly improve self
Band sand ability and intensity, cutting process should not rupture.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the accompanying drawings and tool
The present invention is described in further detail for body embodiment.
Refer to the structure that Fig. 1, Fig. 1 are a kind of detailed description of the invention of cutting steel wire provided by the present invention
Schematic diagram.
In this embodiment, cutting steel wire includes cutting main body 1 and outer wrapping wire 2.
Wherein, cutting main body 1 is in line style, concrete, cutting main body 1 can be diameter between
Steel wire between 0.08mm-0.3mm or aramid fiber yarn, the cross section of cutting main body 1 is preferably circular,
The cutting main body 1 of circular cross section is beneficial to the winding of outer wrapping wire 2.
Certainly, cutting main body 1 is not limited to the steel wire given by the present embodiment or aramid fiber yarn, its
He disclosure satisfy that the material of requirement of strength also can, meanwhile, the shape of cross section of cutting main body 1 can root
It is set according to needs, it is not limited to the shape of cross section gone out given in the present embodiment.
When cutting steel wire uses, the intensity of cutting main body 1 directly affects the intensity of whole cutting steel wire,
And the fineness of outer wrapping wire 2 directly affects band sand ability, therefore, general, cutting main body 1 with
In the case of outer wrapping wire 2 material is identical, the cross section that cross-sectional area is outer wrapping wire 2 of cutting main body 1
Long-pending 4-14 times, certainly, in the case of the intensity making the material itself cutting main body 1 is sufficiently large,
The cross-sectional area of cutting main body 1 can also be 1-4 times of outer wrapping wire 2 cross-sectional area, concrete, it should
Select according to cutting demand.
It addition, outer wrapping wire 2 is along the circumferential spiral winding of cutting main body 1, when this cutting steel wire is in cutting
During the materials such as silicon chip, cutting steel wire moves along the bearing of trend of cutting main body 1, and outer wrapping wire 2 is to cutting
Cut material and produce shearing force, it is easy to cutting.
Concrete, the diameter of outer wrapping wire 2 can be arranged such between 0.08mm-0.14mm,
Both can avoid that outer wrapping wire 2 is meticulous to be easily broken off and band sand difficulty, and outer wrapping wire 2 can have been avoided
Cross and slightly cause the integral diameter of this cutting steel wire to increase, cause the waste of cutting material (such as silicon),
The blanking rate of condition cutting material.Certainly, when the use of this cutting steel wire, it is not necessary to consider cutting material
The waste of material, and when more stressing cutting efficiency, the cross-sectional area of outer wrapping wire 2 and cutting main body 1
Cross-sectional area can be suitable increase.
Further, when the winding of outer wrapping wire 2 is overstocked, processing cost and material cost are the highest, and
When the winding of outer wrapping wire 2 is the most sparse, the band sand ability of outer wrapping wire 2 can be affected, and then cause cutting
Cut efficiency low, therefore, the bearing of trend angle being wound around incline direction and cutting main body 1 of outer wrapping wire 2
Being preferably 60 °-90 °, as shown in ∠ A in Fig. 1, meanwhile, the lay pitch of outer wrapping wire 2 arranges and is preferably
2-5mm, most preferably 3.5mm, as shown in T in Fig. 1.
Certainly, outer wrapping wire 2 is equally steel wire or the aramid fiber yarn that intensity is higher.
Needing exist for explanation, the material of outer wrapping wire 2 is not limited to steel wire or aramid fiber yarn, energy
Enough meet rigidity requirement, there is certain pliability simultaneously, it is simple to the material of winding.
Meanwhile, the outer surface of cutting main body 1 and outer wrapping wire 2 is additionally provided with abrasive coating, wear-resistant coating
Material can be boron nitride particle, silicon-carbide particle or diamond particles etc..
This cutting steel wire, by the outer wrapping wire 2 of peripheral part spiral winding in cutting main body 1, can ensure
On the basis of the intensity that cutting main body 1 has originally, improve the intensity of whole cutting steel wire further, and
And, utilize the outer wrapping wire 2 of spiral winding can be effectively improved the band sand ability of whole cutting steel wire, i.e.
Improve the ability of attachment abrasive coating, improve the cutting efficiency for semi-conducting materials such as silicon.
In this specification, each embodiment uses the mode gone forward one by one to describe, and each embodiment stresses
Being all the difference with other embodiments, between each embodiment, identical similar portion sees mutually i.e.
Can.
