Problems solved by technology

[0002] The existing friction wheel is made by low-pressure casting of the raw material ADC12. The chemical composition of the raw material ADC12 is: Si: 8.5-11.5%, Fe: less than 0.5%, Mg: less than 0.45%, Zn: 0.2%, Al: 82 %, the content of magnesium, iron, and zinc is high, and burning is prone to occur during smelting, and the material is brittle and easy to break; while the content of silicon is high, the melting point is low, and the tensile strength cannot meet the requirements; while the cost of low-pressure casting molds is high , resulting in increased casting costs

Abstract

The invention provides a processing method for a motorcycle hub. When the hub is processed by the method of the invention, the processing cost is low and the performance is stable. The processing method is characterized in that the processing method comprises the steps as follows: aluminium solution melting, casting blank, riser cutting, bottom pore drilling, air nozzle drilling, grinding, T6 heat disposal, shot blasting, single-board computer, cleaning, coating, numerical control processing, finished product detecting, cleaning, packaging, and warehousing. The processing method is characterized in that the contents of all components in the aluminium solution are 6.5 to7.5 percent of Si, less than 0.25 percent of Fe, less than 0.25 percent of Mg, and 0.2 percent of Zn, 92.5 percent of Al; the melting temperature of the aluminium solution is ranging from 705 DEG C to 735 DEG C; and the casting blank is cast by gravity.

Description

technical field [0001] The invention relates to the technical field of wheel hub processing, in particular to a processing method for a motorcycle wheel hub. Background technique [0002] The existing friction wheel is made by low-pressure casting of the raw material ADC12. The chemical composition of the raw material ADC12 is: Si: 8.5-11.5%, Fe: less than 0.5%, Mg: less than 0.45%, Zn: 0.2%, Al: 82 %, the content of magnesium, iron, and zinc is high, and burning is prone to occur during smelting, and the material is brittle and easy to break; while the content of silicon is high, the melting point is low, and the tensile strength cannot meet the requirements; while the cost of low-pressure casting molds is high , leading to increased casting costs. Contents of the invention [0003] Aiming at the above problems, the invention provides a method for processing a motorcycle wheel hub. The wheel hub processed by the method has low processing cost and stable performance. [...
