Abstract
The utility model relates to cutting steel wires in the field of photovoltaics or semiconductors, in particular to a wavy special-shaped cutting steel wire. The cross section of the cutting steel wire is circular or similar to be circular, the integral cutting steel wire is processed into smooth wavy structure, the diameter of the cross section of the cutting steel wire is constant, the distance between each two wave crests ranges from 1mm to 20mm, and the depth of the wave trough ranges from 0.01mm to 0.05mm. Compared with the prior art, the wavy special-shaped cutting steel wire is novel and simple in structure. Due to the fact that the integral cutting steel wire is processed into the smooth wavy structure through a deformer in a deforming manner, tensile strength of the steel wire is increased, stress on the steel wire is reduced, winding displacement of the steel wire on a bobbin is improved, breakage rate of an uncoiling end of the steel wire during cutting is reduced, and abrasive carrying capacity and cutting efficiency are increased. Particularly when used for cutting harder materials or materials difficult to be processed, the wavy special-shaped cutting steel wire brings great convenience to cutting operation.
Description
[technical field]
The utility model relates to the cutting steel wire in photovoltaic or the semiconductor applications, specifically a kind of wavy abnormity cutting steel wire.
[background technology]
At present, the multi-thread cutting of domestic silicon crystal all is to adopt the multi-thread cutting of free abrasive, promptly cuts steel wire and carries the mortar high-speed motion, and the free abrasive in the mortar is under the drive of pressure that cuts steel wire and speed, silicon materials are carried out abrasive type processing, thereby realize 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.In addition, existing cutting tensile strength of wire is less, and wire broken rate is than higher during cutting processing.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.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of wavy abnormity cutting steel wire is provided, and has improved cutting efficiency greatly, has reduced wire broken rate.
Design a kind of wavy abnormity cutting steel wire for achieving the above object, the cross section of described cutting steel wire is circle or sub-circular, described cutting steel wire integral body is processed into level and smooth wavy texture, the cross-sectional diameter of described cutting steel wire is constant, distance between described adjacent two crests is 0.10-1.50mm, and the degree of depth of described trough is 0.01-0.05mm.
The cross-sectional diameter of described cutting steel wire is 0.10-0.40mm.
Described crest, trough are circular arc.
The utility model is compared with prior art, novel structure, simple, cutting steel wire integral body becomes level and smooth wavy texture by the anamorphoser deformation processing, improved tensile strength of wire, reduce steel wire stress, improve the winding displacement of steel wire on I-beam wheel, reduced the wire broken rate of steel wire unwrapping wire end when cutting, improved band amount of abrasive and cutting efficiency.Particularly when some harder or difficult material processed of cutting, the utility model has brought very big convenience for cutting work, be worthy of popularization, and industrialization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, cutting steel wire, 2 is that crest, 3 is trough.
[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 deformation process with existing cutting steel wire through anamorphoser, the level and smooth wavy texture of the whole one-tenth of cutting steel wire, the cross-sectional diameter of described cutting steel wire is constant, described crest, trough are circular arc, distance between described adjacent two crests is 0.10mm, 0.30mm, 0.50mm, 0.80mm, 1.00mm or 1.50mm, and the degree of depth of described trough is 0.01mm, 0.02mm, 0.04mm or 0.05mm.The cross section of cutting steel wire is circle or approximate circle, and cross-sectional diameter is 0.10mm, 0.12mm, 0.20mm, 0.30mm or 0.40mm.During cutting, with of the guiding of this waveform cutting steel wire 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, the mortar that the cutting Steel Wire Surface is carried is along with the high-speed motion of steel wire, directly obtain movement velocity and certain pressure, thereby silicon materials are carried out grinding and 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.
