Abstract
The utility model relates to a cutting steel wire in the photovoltaic field or the field of semiconductors, in particular to a special-shaped cutting steel wire with an abrasive coating. The cutting steel wire is in an elliptic cylinder or polygon structure. The outer surface of the cutting steel wire is provided with an abrasive coating, and the material component of the abrasive coating is SiC or diamond particles. Compared with the prior art, the cutting steel wire has a novel and simple structure; as the cutting steel wire is in the elliptic cylinder or polygon structure, the hardness is improved, and the tensile strength is increased, therefore, the break rate of wire is effectively reduced, the cutting speed of the steel wire is increased, and the cutting efficiency is improved; and particularly, when hard materials or materials difficult for processing are cut, the cutting work is very convenient. In addition, the special-shaped cutting steel wire can directly take part in cutting, and mortar is not needed, so that on the one hand the cost is reduced and the cutting efficiency is greatly increased, and on the other hand the environmental pollution is also reduced.
Description
[technical field]
The utility model relates to the cutting steel wire in photovoltaic or the semiconductor applications, specifically a kind of abnormity cutting steel wire with abrasive coating.
[background technology]
The multi-thread cutting technique of silicon crystal is compared with other cutting techniques, has efficient height, production capacity height, precision advantages of higher.The domestic multi-thread cutting of silicon crystal at present all is to adopt the multi-thread cutting of free abrasive, promptly cut steel wire and carry the mortar high-speed motion, free abrasive in the mortar carries out abrasive type processing to silicon materials under the drive of pressure that cuts steel wire and speed, thereby realizes the silicon crystal cutting.Cutting steel wire itself does not participate in cutting in this process, because the real contact area of free abrasive in the mortar and silicon materials is less, therefore lower to the clearance of rapidoprint, process time is longer, and production efficiency is low.If the harder or difficult to machine material more of processing, the multi-thread line of cut of this free abrasive just is difficult to competent.Can address the above problem and abrasive material is anchored at the multi-thread line of cut that cuts Steel Wire Surface, but be subjected to the restriction of abrasive material at the Steel Wire Surface fixing method at present, abrasive material and steel wire bond strength are not high, and the life-span of steel wire also is restricted.Therefore study novel abrasive material fixing method, and industrialization, can improve cutting efficiency, prolong the steel wire life-span, and in the silicon crystal cutting, reduce width of slit, seem particularly important.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of abnormity cutting steel wire with abrasive coating is provided, and has improved cutting efficiency greatly, effectively reduces cost.
Design a kind of abnormity cutting steel wire for achieving the above object with abrasive coating, described cutting steel wire is oval cylinder or gengon structure, it is characterized in that: described cutting steel wire outer surface is provided with abrasive coating, and described abrasive coating material composition is SiC or diamond particles.
The cross section of described cutting steel wire is triangle, ellipse, rectangle or square.
The cross section average diameter of described cutting steel wire is 0.15-1mm.
The average grain diameter of described SiC, diamond particles is the 5-60 micron.
Described abrasive coating adopts plating mode or glue bonding mode to be fixed on the cutting steel wire outer surface.
The utility model is compared with prior art, novel structure, simple, because the cutting steel wire is oval cylinder or gengon structure, its hardness and tensile strength improve greatly, thereby effectively reduce wire broken rate, accelerated the cutting speed of steel wire, improved cutting efficiency, particularly when some harder or difficult material processed of cutting, brought very big convenience for cutting work.In addition, the utility model can be participated in cutting directly, does not re-use mortar, has reduced cost on the one hand, has improved cutting efficiency greatly, has also reduced the pollution to environment on the other hand.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is structural representation of the present utility model (two);
Fig. 3 is structural representation of the present utility model (three);
Among the figure: 1, SiC or diamond particles 2, abrasive coating 3, cutting steel wire.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in drawings, the utility model carries out forming processes with existing cutting steel wire through mould, make its cross section for oval, square, triangle, the cross section average diameter of cutting steel wire is 0.15mm, 0.20mm, 0.30mm, 0.40mm, 0.60mm, 0.80mm or 1mm, should cut the steel wire unwrapping wire by abnormity then, carry out surface clean, afterwards SiC or diamond particles are fixed on Steel Wire Surface by plating mode or glue bonding mode, form abrasive coating, the average grain diameter of SiC or diamond particles is 5 microns, 10 microns, 15 microns, 20 microns 30 microns, 50 microns or 60 microns, and then carry out surface clean, last take-up.This had the guiding of the abnormity cutting steel wire of abrasive coating by tens guide rollers, on the main line roller, form a bracing cable net, and silicon crystal to be processed is realized the feeding of workpiece by the decline of workbench, because metal abrasives is anchored on the cutting Steel Wire Surface, so in process, the fixed abrasive material on the cutting Steel Wire Surface directly obtains movement velocity and certain pressure along with the high-speed motion of steel wire, directly silicon materials are carried out grinding, thereby realize cutting.
The utility model cutting steel wire purposes not only is used for the cutting of photovoltaic field silicon crystal, also can be used for the cutting of crystal, crystal glass, jewel etc.
The utility model is not subjected to the restriction of above-mentioned embodiment; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
