Diamond wire horizontal sand feeding device

Abstract

A diamond wire horizontal sand feeding device comprises a sand feeding barrel and a sand feeding trough. Openings are formed in the upper end of the sand feeding barrel and the upper end of the sand feeding trough. The bottom of the sand feeding barrel communicates with the bottom of the sand feeding trough through a pipeline. A water pump is mounted on the pipeline. One end of a liquid return pipe is connected with the bottom of the sanding feeding trough, and the other end of the liquid return pipe is connected with the position, close to the upper end, of the sand feeding barrel. A wire feeding groove and a wire outlet groove are formed in the two end faces of the sand feeding trough along the opening in the upper end. A sand feeding pipe is arranged at the position, located under a diamond wire, in the sand feeding trough and communicates with the pipeline. Nozzles are arranged on the sand feeding pipe at intervals, agents including diamond sand are sprayed to a metal wire over the nozzles through the nozzles, and the metal wire is sanded. The sand feeding trough and the sand feeding barrel communicate, the nozzles are arranged at the positions, below the metal wire, of in the sand feeding trough, and the metal wire is sanded. The sand feeding density is flexibly controlled according to actual needs, sand feeding is more even, and the device is simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of gold wire production, in particular to a gold wire horizontal sanding device. Background technique [0002] The gold steel wire made of electroplated diamond abrasive on the surface of the metal wire (that is, the bus bar) is a very common wire saw material in the field of wire cutting technology. It has high cutting efficiency, small kerf, can cut multiple products at the same time, and is environmentally friendly. Many hard materials in the industry are cut with cutting steel wires or higher-quality gold steel wires, such as polysilicon slices, monocrystalline silicon, and ingots in the photovoltaic field. [0003] In the production process of gold steel wire, it needs to go through multiple processes such as wire setting, alkali cleaning, pickling, pre-plating, sanding, and reinforcement. On the surface of the wire, it plays a decisive role in the quality of the final product. However, there are defi...
