Background technology
Cutting steel wire also known as cutting steel wire are that a kind of special hard brittle material is coated with zinc for the wire rod of segmentation and surface
The extraordinary steel wire of copper, it is widely used, it can be used for cutting the hard crisp product of various high-precisions, may act as the abrasive material carrier of multi-wire saw.
In mortar slice field, actually play dissection is mortar (suspension of SiC), and cutting steel wire is sand
The carrier of slurry, therefore, the mortar that can play dissection of carrying is more, and cutting power is stronger.
In recent years, in order to improve the ability that cutting steel wire carries mortar, and in cutting process, occur structure lines or
Helix is used for cutting steel wire using the steel wire for having certain predeformation.
Traditional structure lines or helix, often circular arc is so in the steel of curved bottom to wave tops
Silk do not have dissection, this is because steel wire waveform present circular arc, be unfavorable for carry mortar and with workpiece to be cut
Effective contact is not sufficiently formed, in curved bottom, mortar can't reach the workpiece to be cut.
Utility model content
Purpose of utility model:The purpose of this utility model is to provide a kind of cutting steel wires with trapezoidal waveform, have
The appearance sand area of bigger has stronger cutting power.
Technical solution:To realize above-mentioned purpose of utility model, the utility model adopts the following technical solution:

Advantageous effect:Compared with prior art, a kind of cutting steel wire with trapezoidal waveform of the utility model, by changing
Kind effectively to hold sand area, steel wire can carry more mortars, allow the mortar of carrying in position advantageously, be convenient for and to be cut
Workpiece form effective contact, have stronger cutting power.
Specific implementation mode
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate.
As shown in Figs. 1-2, a kind of cutting steel wire with trapezoidal waveform, the trapezoidal waveform include the trapezoidal sections of period setting
And linkage section, it is connected by linkage section between trapezoidal sections.
Linkage section is bottom level section.Trapezoidal sections are the cutting steel wire of isosceles trapezoid, including two oblique line sections and top water
Flat section.
The trapezoidal waveform can be overlapped to form solid figure to be multigroup on one group or different directions.
Steel wire diameter φ is 0.04mm-5mm.
The ratio of trapezoidal wave top horizontal section L1 and wavelength L are 0.1-0.95.
As shown in Fig. 2, a kind of preparation method of the cutting steel wire with trapezoidal waveform:Allow steel wire by one group (or not
It is equidirectional multigroup), the gear with flat-top, so that it may to process the cutting steel wire with trapezoidal waveform.
The wave height of trapezoidal waveform is 0.05 times~2 times of cutting steel wire diameter.
Top horizontal section is flat, is not round, in the case of same wave height (causing same widths saw kerf), compared to top
Portion is circular waveform, can carry more mortars, thus has stronger cutting power;Due to top horizontal section and bottom level
Section is flat, therefore the mortar carried more easily effectively touches workpiece to be cut, thus has stronger cutting power.
The above waveform can also be used, and consolidate (using the steel wire with trapezoidal waveform of principles above as diamond wire busbar,
Then consistent with the production technology that current plating diamond wire is general in the method consolidated diamond that electroplated diamond is used above)
Diamond forms diamond wire.
Using the cutting steel wire of this programme, the mortar for carrying dissection is more, therefore cutting power is stronger, can be improved
Cutting efficiency improves cutting products quality.
