Description
Technical field
The present invention relates to a kind of isomery steel wire and its manufacture device and preparation method for multi-wire saw, the steel wire is applicable
In hard materials such as multi-wire saw crystalline silicon, carborundum, sapphire, crystals.
Background technology
In most cases, multi-wire saw is, using high intensity steel wire as carrier, to be carried in high-speed motion by steel wire
Super hard abrasive, by abrasive material to high hard material（Such as crystalline silicon, carborundum, sapphire, crystal etc.）Carry out rolling and dig grinding to realize
Cutting.Which with cutting efficiency it is high, saw kerf is small for cutting, material loss less, cutting accuracy is high, surface quality is good the advantages of turn into
The current main mode of production.Wherein, steel wire is used as the carrier for carrying abrasive material, stability and carrying mill in cutting process
The ability of material, extremely important effect is played for cutting efficiency and product quality.
Now widely used steel wire is the smooth circular configuration in surface, and it has the prominent advantages that steel wire can be around it
The direction for cutting feeding uniformly carries abrasive material, so as to bring the cutting surfaces quality of stabilization.Under normal circumstances, can be by increasing
The diameter of steel wire increases the surface area of steel wire, so as to strengthen steel wire carry the ability of abrasive material to improve cutting efficiency, cost be by
This can cause the width of saw kerf to increase, so as to bring the increase of material loss in cutting process.The lifting of cutting efficiency can also lead to
The modes such as the average grain diameter and corner angle sharpness of increasing abrasive material are crossed to realize.
Almost while multi-wire saw is born, pursue and improve steel wire（Sawline）The effort of abrasive material carrying capacity opened
Begin and be continued for so far, can typically be divided three classes：
The first kind is attempt to manufacture coarse steel wire, and the abrasive material for increasing steel wire by the roughness for increasing steel wire surface carries energy
Power.Such as JP2007196312 is proposed by way of to steel wire surface jet electrolytic liquid, causes steel wire surface to produce concavo-convex；
WO9/12670 then proposes the concepts such as the steel wire that nick chamber steel wire, pressure release surface steel wire, and cross section change along its length；
KR2001002689 then describes a kind of annular saw line, and cavity is formed on the annular saw line by way of pressing and carving.Such trial is so far
The modern industrializing implementation for not yet being succeeded in multi-wire saw field and application, it is powerful that core reasons are that abrasive material possesses in itself
Wear resistance, by the steel wire surface of above-mentioned treatment, can be polished so that at surface soon in cutting process is entered
The steel wire of reason is with the smooth steel wire in conventional circular surface there is no any difference.
It is based on carrying out spiral treatment to steel wire that Equations of The Second Kind is attempted.For example, JP2007044841 proposes a kind of base
This is circular sawline, and with the flat horizontal surface that the length direction spirality around sawline extends, CN102380915A is essentially
The natural extension of above-mentioned concept；US2860862 then proposes to apply spiral deformation twice to the sawline for making flat pattern in advance：
Own axes first with the short lay pitch around flat sawline are twisted, and then sawline is twisted with screw type with the longer lay pitch.
FR750081 also illustrates the spirality sawline using circular or polygonal crosssection.CN102205563A and
CN102765141A is substantially the natural extension of foregoing thinking.JP4057666 then describes a kind of metal sawline, is equally
Straight steel wire is become into screw type in advance by the way of twisting, is stretched by drawing-die again afterwards.So far, above-mentioned effort
Successful industrializing implementation and application are equally had no in multi-wire saw field, core reasons are that the spiralization of steel wire can not be kept away
Need with exempting to twist steel wire, so as to bring torsion internal stress very high to steel wire, and steel wire is more long, reverse Inner stress and get over
Height, so as to cause finished product steel wire to produce self strong clot to be inclined to, it is impossible to be applied to multi-wire saw, outstanding behaviours is very
Hardly possible completes uniform long range taking-up, and wiring or cannot be difficult on the net in line of cut, even if reluctantly for short distance cutting,
As the self-contained internal stress of reversing high of steel wire causes the irregular shake of gauze, lead to not the cutting effect for receiving
（Protrusion is presented as that surface line marker is bad with TTV）.
3rd class is attempted, and is by way of being bent in one or more planes to steel wire, to manufacture so-called " knot
Structure steel wire ".Such as JP2004276207 is also described outside one kind is described with spiral deformation single line or twisted wire
State single line or twisted wire is conducted through a pair of cogwheels, so as to form double gauffers of zigzag in single plane.In zigzag wrinkle
In pleat, sawline is first bent in a first direction, and second bending and opposite with first direction is then carried out in a second direction（Instead
To bending）, then the zigzag gauffer of short length is added in long wave spirality by twisted wire and sth. made by twisting again.This kind is attempted
Open defect, be that twisted wire structure can cause the practical envelope external diameter of sawline significantly to increase, bring the saw kerf for being difficult to receive to add
Additional materials loss wide and corresponding.
3rd class achieves certain application success in attempting, and is that Anselmi tal fibre company passes through Chinese patent
A kind of monofilament metal saw wire disclosed in CN100475398C, it has carried out curved in two or more planes to steel wire
Song, so as to good effect can be obtained under some specific application environments in the ability for enhancing steel wire carrying abrasive material to a certain degree
Really.Have a disadvantage in that, the bending of the sawline is leading with a plane, and the bending of other planes can be by gradually in cutting process
The leading plane is redirect to, is ultimately formed substantially only in a sawline for plane internal deformation, so as to cause cutting yield to fluctuate,
Simultaneously because the structure holding capacity of the sawline is limited, in the case where cutting path is more long, when line of cut reaches cutting tail end
Warp architecture is basic or big portion disappears, and causes the yield for cutting tail end to be declined to a great extent compared with the yield of cutting initiating terminal.To taste
Examination solves drawbacks described above, and NV Bekaert SA proposes one kind equivalent to Equations of The Second Kind by CN102528940A（" spiral steel wire "）
With the 3rd class（" structure steel wire "）Thinking blended product concept, Basic practice is on a single plane using the embedding gear stung
（Or other deformation devices）Bending is made to steel wire, is twisted by steel wire（Around the axis rotational deformation device of steel wire
Place plane, or keep plane where deformation device motionless but synchronous rotary retractable bobbin）, form spirality steel wire, Zhi Houzai
Untwisting is carried out to steel wire（Plane where deformation device is reversely rotated with twist direction, or keeps deformation device place plane motionless
But reverse sync rotates retractable bobbin）The torsion internal stress of steel wire is brought due to twisting partly or entirely to discharge.In implementation
It was found that, because necessary untwisting, no matter cause the steel wire being made around each in uniformity of axis, or keep in structure
Ability aspect, does not produce raising compared with the method that CN100475398C is provided.CN102962901A and CN102310489A are then equal
It is, in the notional extension naturally of CN100475398C and CN102528940A, to have no that independent technique is contributed.
With continual cost efficiency effort in industry, multi-wire saw just increasingly uses longer workpiece（Silicon rod
Deng）, thinner cutting steel wire（0.08mm-0.115mm）, cause cutting path constantly to lengthen, further limit to above-mentioned tradition
The scope of application of structure lines.
The content of the invention
The technical problem to be solved in the present invention is：The ability that steel wire carries abrasive material in cutting process is improved, while solving
The structure steel wire of conventional planar curling is not because structure holding capacity brings by force the problem of cutting afterbody yield downslide risk.
Above-mentioned technical problem, especially outstanding behaviours to reduce saw kerf requirement it is higher, but cutting object simultaneously again it is more long
Solar energy crystal silicon section aspect：With the raising of cutting technique level, at present in most cases, used in crystal silicon section
The diameter of cutting steel wire, between 0.09mm-0.13mm, per knife, the amount of production silicon chip is higher than 2300, this fine rule/height
Tension force/long-range cutting, the structure holding capacity for the traditional structure steel wire of plain bending proposes stern challenge.
The technical solution adopted for the present invention to solve the technical problems is：A kind of isomery steel wire for multi-wire saw,

Isomery steel wire of the present invention, application is the precision to reducing kerf loss requirement high hard material higher
Cutting, therefore accurate high-carbon steel or high carbon alloy steel wire using itself average diameter between 0.08mm -0.15mm.With plane
The traditional structure steel wire of bending is compared, and isomery steel wire increased the twist part for no longer sharing any plane outside plane curling,
The stereochemical structure of steel wire is more complicated, band sand ability further enhance, simultaneously as distortion isomery presence and isomery into
Working hardening during type, also makes isomery steel wire possess the structure holding capacity stronger compared with traditional structure steel wire.With tradition
Structure steel wire similarly, although increase isomery steel wire circumscribed enveloping diameter can improve band sand ability（It is presented as cutting efficiency
Lifting）, but under typical fine rule/high-tension/long-range cutting combination, excessive circumscribed enveloping diameter also results in isomery steel wire
Structure is easy to disappear, and brings the risk that stria and the bad grades of TTV are produced in cutting process to increase（Namely the stabilization of cutting yield
Property decline）If the circumscribed enveloping diameter of the isomery steel wire of selection is too small, and it can be brought to compare with sand ability with ordinary straight steel wire
Improve not notable enough.Unify to apply the outside of 5 newton in order to more accurately characterize the pattern of isomery line finished product, when measuring it
Power, the measurement noise brought because natural shrinking is inclined to excluding isomery steel wire in its natural state.Substantial amounts of experimental evidence
