Abstract
The invention relates to the technical field of cutting steel wires, in particular to a cutting steel wire with sawtooth elements. The cutting steel wire comprises a cutting steel wire body, and the cutting steel wire body is bent to be distributed in a sawtooth manner; each sawtooth comprises a long side and a short side; the projected length of the long sides in the horizontal direction is L1, and the projected length of the short sides in the horizontal direction is L2; and L1/L2 ranges from 1 to 5. By the adoption of the structure, the rigidity of a resin layer is low, and a copper plating layer can effectively protect the cutting steel wire body against abrasion in the process of workpiece cutting; the thickness of a damaged layer of a cutting face of a machined workpiece is lower than that of a plating line, and the section stress is small; and in addition, diamond micro powder particles can cut the workpiece well, the feeding speed of the cutting steel wire is improved, and the cutting efficiency is improved.
Description
Technical field
The present invention relates to cutting steel wire technical field, particularly a kind of cutting steel wire with sawtooth element.
Background technology
In the segmentation slice process of the hard brittle materials such as the silicon crystal in electronics and field of solar energy, general be all by by metal monofilament-be commonly called as cutting steel wire in turn winding in the guide groove of some home rolls, make home roll rotate again and drive cutting steel wire to move reciprocatingly, thus bring the grinding agent of extreme hardness into cutting mouth by the reciprocating motion of cutting steel wire, grinding agent constantly grinds silicon crystal under the reciprocating motion of metal monofilament, and then realizes the cutting burst to silicon crystal.
Chinese invention patent CN103692567A discloses a kind of flat cross section zigzag cutting steel wire, comprise: cutting steel wire, the cross section of cutting steel wire is that flat is arranged, cutting steel wire is continuous print notched profile along its axial direction, in cutting steel wire, the length of the sawtooth minor face of sawtooth is 1/3-1/2 times of the length on the long limit of sawtooth, the height of sawtooth is 0.15-0.3 times of the height of cutting steel wire flat cross-section, and the width of cutting steel wire flat cross-section is 0.7-0.9 with the ratio of height.Although, this invention decreases the afterbody stria of silicon crystal cut surface, improve the surface smoothness of silicon crystal cut surface, further increase the cutting stability of cutting steel wire, and arranged by the continuous uniform zigzag of cutting steel wire along its axial direction, improve the silicon rod feeding rate of cutting steel wire, improve cutting efficiency; But the waveform hold facility of this invention is poor, and the wearing and tearing of waveform are larger.
Summary of the invention
The technical issues that need to address of the present invention provide the cutting steel wire that a kind of waveform hold facility is good.
For solving above-mentioned technical problem, a kind of cutting steel wire with sawtooth element of the present invention, comprise cutting steel wire body, described cutting steel wire body bent upon itself becomes sawtooth to distribute, described sawtooth comprises long limit and minor face, described long edge horizontal direction projected length is L1, and minor face in the horizontal direction projected length is L2, and described L1/L2 is between 1-5.
Further, copper coating is coated with outside described cutting steel wire body.
Further, described copper plate arranged outside is solidified with uncured resin layer, is distributed with diadust particle in described uncured resin layer.
Further, the particle diameter of described diadust particle is 5-50 μm.
Adopt said structure, resin bed rigidity of the present invention is low, and copper coating can effectively protect cutting steel wire body not to be worn in the process of cut workpiece; Process work piece cut surface damage layer thickness lower than plating line, section stress little.In addition, diadust particle can well cut workpiece, improves the feeding rate of cutting steel wire, improves cutting efficiency.

Detailed description of the invention
As shown in Figure 1, a kind of cutting steel wire with sawtooth element of the present invention, comprise cutting steel wire body 1, described cutting steel wire 1 body bent upon itself becomes sawtooth to distribute, described sawtooth comprises long limit 2 and minor face 3, and described long limit 2 in the horizontal direction projected length is L1, and minor face 3 in the horizontal direction projected length is L2, the ratio of long limit 2 projected length and minor face 3 projected length in the horizontal direction is in the horizontal direction partial wave ratio, partial wave than L1/L2 between 1:1 to 5:1.Due to a minor face 3, when stressed in the horizontal direction, the cutting steel wire with zigzag element can have good waveform hold facility.
Further, as shown in Figure 2, be coated with copper coating 4 outside described cutting steel wire body, copper coating 4 can effectively protect cutting steel wire body 1 not to be worn in the process of cut workpiece.
Further, described copper plate 4 arranged outside is solidified with uncured resin layer 5, is distributed with diadust particle 6 in described uncured resin layer 5.Diadust particle 6 can well be fixed on outside cutting steel wire body 1 by uncured resin layer 5.Uncured resin layer 5 rigidity is low, process work piece cut surface damage layer thickness lower than plating line, section stress little.In addition, in the process of cut workpiece, diadust particle 6 can well cut workpiece, improves the feeding rate of cutting steel wire, improves cutting efficiency.
Further, the particle diameter of described diadust particle is 5-50 μm.
Although the foregoing describe the specific embodiment of the present invention; but those skilled in the art are to be understood that; these only illustrate; various changes or modifications can be made to present embodiment; and not deviating from principle and the essence of invention, protection scope of the present invention is only defined by the appended claims.
