Device for adjusting wire net distance in wire saw machining process and machining method

Abstract

The invention discloses a device for adjusting the wire net distance in the wire saw machining process and a machining method. Bearing inner rings and a shaft body are relatively fixed, guide wheels and bearing outer rings are relatively fixed, and when the shaft body is fixed, the guide wheels can rotate in the circumferential direction relative to the shaft body for wire cutting. When the distance between the guide wheels needs to be adjusted, only the connecting positions of adjusting pieces and the shaft body need to be changed, if thrust is applied to the guide wheel located on the most side edge, the positions of all the guide wheels can be changed at the same time, the distance between the guide wheels is always kept consistent under the action of magnets and elastic pieces, at the moment, only the distance between any two guide wheels needs to be measured, and the distances between all the guide wheels can be obtained. The device is simple in structure and convenient to adjust, the efficiency of adjusting the wire saw distance is greatly improved, and the labor cost is greatly reduced.

Description

technical field [0001] The invention relates to a device and a processing method for adjusting wire net spacing during wire saw processing. Background technique [0002] Hard and brittle materials such as monocrystalline silicon, polycrystalline silicon, SiC, and ceramics have excellent physical and chemical properties such as high strength, high hardness, wear resistance, and heat resistance, and are widely used in technical fields such as photovoltaic power generation, lasers, and high-temperature heat dissipation. However, because hard and brittle materials have the characteristics of high hardness and low toughness, they are easily broken when sliced, so it is difficult to process such materials. However, using the multi-wire cutting method of diamond wire saw, the raw material can be cut into hundreds or even thousands of slices or hundreds or even thousands of micro channel, greatly improving the processing efficiency. [0003] Most of the existing diamond wire saw m...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing diamond wire saw multi-wire cutting equipment is equipped with custom-made guide wheels with equal groove pitch. If the slice thickness of the workpiece or the spacing between micro-channels changes, the guide wheels must be redesigned and rewound. , at the same time, in order to ensure the machining accuracy, repeated positioning is required, which is very cumbersome
