Description
Technical field
The utility model relates to a kind of isomery steel wire and manufacturing installation thereof for multi-wire saw, and this steel wire is applicable to the hard materials such as multi-wire saw crystalline silicon, carborundum, sapphire, crystal.
Background technology
In most cases, multi-wire saw is using high strength steel wire as carrier, is carried super hard abrasive by steel wire in high-speed motion, by abrasive material, high hard material (as crystalline silicon, carborundum, sapphire, crystal etc.) is rolled to dig and grinds to realize cutting.The advantages such as which is high with cutting efficiency, cutting saw kerf is little, material unaccounted-for (MUF) is few, cutting accuracy is high, surface quality is good become the current main mode of production.Wherein, steel wire is as the carrier that carries abrasive material, and the stability in cutting process and the ability of carrying abrasive material, all play extremely important effect for cutting efficiency and product quality.
Now widely used steel wire is ganoid circular configuration, and its outstanding advantages is that steel wire can evenly carry abrasive material around the direction of its cutting feeding, thereby brings stable cutting surfaces quality.Under normal circumstances, can increase by increasing the diameter of steel wire the surface area of steel wire, thereby enhancing steel wire carries the ability of abrasive material to improve cutting efficiency, cost is that the width that can cause thus saw kerf increases, thereby brings the increase of material unaccounted-for (MUF) in cutting process.The lifting of cutting efficiency also can realize by the mode such as average grain diameter and corner angle sharpness that strengthens abrasive material.
Almost, when multi-wire saw is born, the effort of pursuing the abrasive material carrying capacity that improves steel wire (sawline) has started and has continued always so far, typically can be divided three classes:
The first kind is to attempt to manufacture coarse steel wire, increases the abrasive material carrying capacity of steel wire by increasing the roughness on steel wire surface.For example JP2007 196312 has proposed by the mode to steel wire jet surface electrolyte, causes steel wire surface to produce concavo-convex; 9/12670 of WO has proposed nick chamber steel wire, pressure release surface steel wire, and the concept such as the steel wire that changes along its length of cross section; 2,001 002689 of KR have described a kind of annular saw line, and the mode of carving by pressure forms cavity on this annular saw line.This type of attempts the industrializing implementation and the application that not yet succeed in multi-wire saw field so far, core reasons are that abrasive material itself possesses powerful wearing and tearing ability, through the steel wire surface of above-mentioned processing, soon can be polished entering in cutting process, make surface treated steel wire and the smooth steel wire of conventional circular surface no longer include any difference.
It is to be treated to basis so that steel wire is carried out to spiral that Equations of The Second Kind is attempted.For example, it is circular sawline substantially that JP 2,007 044841 has proposed a kind of, has the flat horizontal surface extending around the length direction spirality of sawline, and CN102380915A is naturally extending of above-mentioned concept substantially; 2860862 propositions of US apply the distortion of twice spirality to making in advance the sawline of flat pattern: first self the axis twisting around flat sawline by the short lay pitch, then the longer lay pitch of use is twisted sawline with screw type.FR 750081 has also described the spirality sawline that adopts circle or polygon cross section.CN102205563A and CN102765141A are naturally extending of aforementioned thinking substantially.JP4057666 has described a kind of metal sawline, is equally to adopt the mode of twisting that straight steel wire is become to screw type in advance, stretches afterwards by drawing-die again.Up to now, above-mentioned effort has no successful industrializing implementation and application equally in multi-wire saw field, core reasons are, the unavoidable ground of spiralization of steel wire need to be twisted steel wire, thereby bring very high torsion internal stress to steel wire, and steel wire is longer, reverse Inner stress higher, thereby cause finished product steel wire to produce strong self-clot tendency, cannot be applied to multi-wire saw, outstanding behaviours is being difficult to uniform length apart from taking-up, cannot or be difficult to wiring on the net at line of cut, even if cut for short distance reluctantly, also can reverse internal stress because of the self-contained height of steel wire and cause the irregular shake of gauze, cause unacceptable cutting effect (outstanding be presented as surface line marker and TTV bad).
The 3rd class is attempted, and is by steel wire being carried out in one or more planes to bending mode, manufactures so-called " structure steel wire ".For example JP 2,004 276207 has outside spiral distortion single line or twisted wire having described one, has also described above-mentioned single line or twisted wire and has been conducted through a pair of cogwheel, thereby in single plane, formed two gauffers of zigzag.In zigzag gauffer, sawline is first bending in a first direction, then in second direction, carries out bending and contrary with first direction (back-flexing) for the second time, and then by twisted wire sth. made by twisting, the zigzag gauffer of shorter length is added in long wave spirality.The open defect of this kind of trial, is that twisted wire structure can cause the practical envelope external diameter of sawline significantly to strengthen, and brings the saw kerf that is difficult to accept to widen and corresponding additional materials loss.
The 3rd class has obtained certain application success in attempting, that Anselmi tal fibre company is by the disclosed a kind of monofilament metal saw wire of Chinese patent CN100475398C, it has carried out bending to steel wire in two or more planes, thereby under some specific application environment, can obtain good result in the ability that has to a certain degree strengthened steel wire and carry abrasive material.Its defect is, the bending of this sawline is taken as the leading factor with a plane, the bending of other planes can be redirect to gradually this leading plane in cutting process, the final only sawline at a plane internal deformation that forms substantially, thereby cause cutting yield fluctuation, simultaneously because the structure hold facility of this sawline is limited, in the situation that cutting path is grown, line of cut arrive cutting when tail end warp architecture basic or large portion disappear, the yield that the yield that causes cutting tail end cuts initiating terminal declines to a great extent.For attempting addressing the aforementioned drawbacks, NV Bekaert SA has proposed one by CN102528940A and has been equivalent to Equations of The Second Kind (" spiral steel wire ") and the 3rd class (" structure steel wire ") thinking blended product concept, Basic practice is that the gear (or other deformation devices) that utilizes embedding to sting on single plane is made bending to steel wire, by steel wire being twisted (around the axis rotational deformation device place plane of steel wire, or keep plane motionless but synchronous rotary in deformation device place to receive, paying out reel), form spirality steel wire, again steel wire is carried out to untwisting (with twist direction reverse rotation deformation device place plane afterwards, or keep plane motionless but reverse sync rotation in deformation device place to receive, paying out reel) partly or entirely to discharge the torsion internal stress that brings steel wire due to twisting.In enforcement, find because necessary untwisting, cause the steel wire made no matter around axis respectively in uniformity, or aspect structure hold facility, the method all not providing compared with CN100475398C produces and improves.CN102962901A and CN102310489A are in CN100475398C and the notional extension naturally of CN102528940A, have no independent technique contribution.
Along with continual cost efficiency effort in industry, multi-wire saw just more and more adopts longer workpiece (silicon rod etc.), thinner cutting steel wire (0.08mm-0.115mm), causes cutting path constantly to lengthen, and has further limited to the scope of application of above-mentioned traditional structure line.
Summary of the invention
The technical problems to be solved in the utility model is: improve the steel wire ability of carrying abrasive material in cutting process, solve the curling structure steel wire of conventional planar simultaneously because structure hold facility not strong band cut the problem of afterbody yield downslide risk.
Above-mentioned technical problem, especially outstanding behaviours is being had relatively high expectations to reducing saw kerf, but simultaneously longer solar energy crystal silicon section aspect again of cutting object: along with the raising of cutting technique level, at present in most cases, the diameter of the upper cutting steel wire adopting of crystal silicon section,, between 0.09mm-0.13mm, every cutter is produced the amount of silicon chip higher than 2300, the cutting of this fine rule/high-tension/long-range, has proposed stern challenge for the structure hold facility of the traditional structure steel wire of plain bending.
