Diamond wire horizontal sand feeding device

Abstract

A horizontal sand loading device for a gold steel wire, comprising an upper sand cylinder and an upper sand tank; the upper ends of the upper sand cylinder and the upper sand tank are open, and the bottom of the upper sand cylinder is connected to the bottom of the upper sand tank through a pipeline, and a water pump is installed on the pipeline One end of the liquid return pipe is connected to the bottom of the upper sand tank, and the other end is connected to the upper end of the upper sand tank. The two ends of the upper sand tank are respectively provided with an inlet slot and an outlet slot along the upper opening. The upper sand tank is located directly below the gold steel wire. A sand feeding pipe, the sand feeding pipe is connected with the pipeline, and nozzles are arranged at intervals on the sand feeding pipe, and the liquid medicine containing corundum is sprayed to the metal wire directly above through the nozzles, and the metal wire is sanded. By connecting the upper sand tank with the upper sand cylinder, the upper sand tank is located below the metal wire line to set the nozzle to sand the metal wire, and flexibly control the sand density according to the actual needs, and the sand is more uniform. The device of the present invention is simple. Easy 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...
