Manufacturing process of aluminum alloy wheel

Abstract

The invention discloses a manufacturing process of an aluminum alloy wheel. The manufacturing process of the aluminum alloy wheel comprises casting, deburring, soaking, spinning, heat treatment, gateremoving, X-ray, and machine addition. According to the manufacturing process of the aluminum alloy wheel, the cost is saved by about 18 yuan / part from the casting production efficiency, the improvingof products quality, the saving of original cooling compressed air, the cancelling of pre-machine addition, the temperature preheating and spinning of blank strip and the temperature pretreating of blank strip and the like; the weight of finished products are reduced by 0.7-1.1 kg, the comprehensive manufacturing cost of the aluminum alloy wheel is even with that of a common casting wheel, and and the market competitiveness of a casting and spinning wheel is improved; and short-flow, lightweight and low-cost technology for manufacturing the cast and spinning wheel is realized, the intelligentization of machining is realized, and the manufacturing process is suitable for automatic production of large-scale casting and spinning wheels.

Description

Technical field [0001] The invention relates to the field of wheel manufacturing, in particular to a manufacturing process of cast-rotating aluminum alloy wheels. Background technique [0002] The cast-spin aluminum alloy wheel is an aluminum alloy wheel in which the spokes are formed by a low-pressure casting process and the rim is formed by a powerful spinning process. The process flow is: casting----cooling----X-ray---de-gating----milling platform----pre-machine adding----preheating----spinning-- --Cooling----Heat treatment----Machining. At present, this kind of process has caused the blank temperature to not be effectively used, the utilization rate of metal materials is low, and the manufacturing cost is high. At the same time, the tempo of casting and spinning is inconsistent and cannot be realized. Automatic connection production.

AI Technical Summary

Problems solved by technology

There is no X-ray inspection in the manufacturing process of this invention, and the pre-machining is canceled, which respectively cause safety hazards in the subsequent wheel hubs of the die-casting process and the spinning process

Although the improvement of the casting machine and the mold improves the quality of the cast product, it cannot guarantee that the product 100% meets the customer's standard, and the customer requires that the product must be 100% fully inspected by X-ray. At the same time, the process does not have a short process layout. To describe, the die-casting process takes a long time, while the spinning process takes a short time, so there must be a reasonable match to realize automated in-line production
