High-wear-resistant driving wheel

Abstract

The invention discloses a high-wear-resistant driving wheel used on a crystal silicon cutting squaring machine. The high-wear-resistant driving wheel comprises an aluminum embedding element, wherein a polyurethane layer is formed on the aluminum embedding element through injection molding, a plurality of grooves are arranged on the circumference of the polyurethane layer, a T-shaped groove is arranged on the aluminum embedding element, the combination intensity of the polyurethane layer and the aluminum embedding element is improved, and the service life of products is prolonged. The polyurethane layer adopts a double-layer structure, the inner layer adopts ordinary wear-resistant materials, the outer layer adopts high-wear-resistant materials, on one hand, the cost of products is reduced, on the other hand, the products can be recovered and reused after being abraded, after the recovery, the polyurethane layer at the outer layer is peeled off, surface dirt is washed away by cleaning agents, then, the injection molding is carried out, and the recovery and reutilization process is completed. The recovery cost is reduced, the repeated use times are many, the high-wear-resistant driving wheel can be averagely recovered for ten times, and the effect of environmental-protection utilization is reached.

Description

technical field [0001] The invention relates to a driving wheel used in a cutting machine, in particular to a driving wheel used on a crystal silicon cutting square cutter. Background technique [0002] The diamond wire squaring machine is a new type of equipment for crystalline silicon cutting for photovoltaic power generation. Its special feature is that this model is cut with diamond wire. At present, the cutting process of photovoltaic crystalline silicon in the world is mainly carried out with copper-plated steel wire. Cutting, copper-plated steel wire cutting must use the suspension mixed with silicon wafer cutting fluid and silicon carbide as the medium, the cutting cost is high, the cutting cycle is long, and the waste suspension treatment after use will cause huge environmental pollution. The diamond wire is prepared by fixing the diamond abrasive on the metal wire. The diamond abrasive replaces the suspension as the cutting medium. Only pure water is used as the co...

AI Technical Summary

Problems solved by technology

[0004] (1) The average service life is 80-100 hours, and it takes about 2 hours for the operator to completely replace each time it is used up, which increases maintenance costs and affects the efficiency and production capacity of the square cutter;

[0005] (2) The imported materials of the drive train have a long procurement cycle and high procurement costs, which cannot be recycled and reused;

[0006] (3) When imported drive wheel products are used, there is a phenomenon that the joint of polyurethane and aviation aluminum material falls off
