Steel wire used for cutting and manufacturing method thereof

Abstract

The invention provides a steel wire used for cutting, which is of a continuously circulating sawtooth type longitudinally. The invention also provides a method for manufacturing the steel wire for cutting, wherein two working gears are pressed oppositely at a fixed position, and the steel wire is continuously formed through the rotating press of the two working gears. The invention also provides a manufacturing device, comprising an upper assembly, a lower assembly, two blocks of wallboards, two springs, two pressure control screws and a bracket, wherein the upper assembly and the lower assembly are composed of two standard gears, a working gear, a wheel axle, a bearing, a bolt and a nut; a working gear is clamped between two standard gears; the pressure control screw with a tension spring hole is respectively arranged in the spindle head hole at two ends of the spindle shaft of the upper assembly; a tension spring is installed in the tension spring hole of the pressure control screw; and the other end of the tension spring is installed at the shaft end of the wheel shaft of the lower assembly. The invention solves the problem of low speed of traditional cutting steel wire belt sand liquid, thus making up the defects of the prior art.

Description

technical field [0001] The invention relates to a steel wire for cutting and a manufacturing method thereof, in particular to a special-shaped cutting steel wire for rapidly cutting silicon wafers and a manufacturing method thereof, and also relates to a device for manufacturing the steel wire for cutting. Background technique [0002] Because the use of solar power generation is relatively new and expanding at home and abroad, the main material silicon wafers in demand are sawn and cut into slices from the raw material silicon rods to produce photosensitive plates. The silicon material is relatively expensive, the material is hard in nature, and the silicon wafers made are very thin, in order to improve the utilization rate of the material. In conventional sawing, the steel wire is used to drive the medium and fine sand to cut. In order to facilitate the driving of the sand by the steel wire, the steel wire is usually used to cut the single polycrystalline silicon wafer. T...
