High-wear-resistant driving wheel processing process

Abstract

The invention discloses a processing process of a high-wear-resistant driving wheel used in a crystalline silicon cutting machine. In the processing process, a two-time injection molding process is adopted, an inner layer is prepared from a common wear-resistant material and an outer layer is prepared from a high-wear-resistant material, thus on one hand, the product cost is lowered, and on the other hand, after the product is worn, the outer polyurethane layer is stripped off and injection-molding is carried out so as to finish a recycling reutilization process, therefore, the recycling cost is lowered, the reuse time of the high-wear-resistant driving wheel is high, the high-wear-resistant driving wheel can be recycled 10 times averagely, and an environmentally-friendly utilization effect is achieved. Before the first injection molding, heat treatment is carried out on an aluminum insert, thus the phenomenon of wrinkle and bubble existing on the injection-molded layer surface due to overlarge temperature difference between the aluminum insert and the injection-molded layer and the product yield is improved; and before mechanical processing, the secondary injection-molded product is subjected to heat insulation treatment, thus the problem of fluffing on the surface of the driving wheel in the use process is solved, materials are not stuck to the product surface during the mechanical processing of the product, and smoothness and cleanness of the mechanically processed product are guaranteed.

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...

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 between polyurethane and aviation aluminum material falls off, and the polyurethane material in the grooved corner of the surface "fluffs". The fluffed polyurethane adheres to the steel wire with the operation of the diamond wire, which will cause the diamond wire disconnected
