Novel high-wear-resistant driving wheel

Abstract

The invention discloses a novel high-wear-resistant driving wheel used on a single crystal silicon cutting squaring machine. The novel high-wear-resistant driving wheel comprises an aluminum embedding element, wherein a polyurethane layer is formed on the aluminum embedding element through injection molding, the polyurethane layer is in a double-layer structure, the inner layer is made of TPU359X materials, the outer layer is made of a mixture obtained through mixing TPUTK95A materials and 3M polytetrafluoroethylene wear-resistant agents according to a weight ratio of 1:(80-100). On one hand, the cost of products is reduced, the wear-resistant performance and the smooth finish are enhanced, and the wear-resistant coefficient is increased by more than 1.7 after the addition of the wear-resistant agents; and on the other hand, the recovery and the reutilization can be realized, and the recovery cost is further reduced.

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 driving wheel train have a long procurement cycle and high procurement costs, which cannot be recycled and reused
