| The world’s first car was born in 1886, in its 120 years of history in the process of development, car from the original transportation evolved into People’s Daily consumer goods, security and comfort become mainstream and trend of the development of the car today. Aluminum wheel hub as an important part of automobile chassis, it is not only used to support the tire, it is the carrier of motor sport, bearing the weight of the safety of car driving. Although wheel tend to be more complex, modelling and pattern design, but as an important indicator of revolving balance demands more and more get the attention of manufacturers, because it not only reflect the comfortableness of driving, in the car safety is becoming more and more attention.This article through to the wheel rotational symmetry of systematic research, combining with the modern production technology of wheel hub, first in the new stage in the product design and mold manufacturing and trial production stage in the design of the optimization and validation;Effective analysis of the effect of blank deformation in the process of production factors, through the optimization of casting process and standardization of mold assembly reduce the effects of deformation of the blank, the combination of technical improvement on the automatic lathe fixture fixture accuracy, reduce the deformation and the machining of the accumulated error.In this paper, through the aid of 3 d digital scanning technology to increase the mould condition monitoring, to assure the consistence of part of the mould, satisfy the requirement of the product rotational symmetry precision,Through the finite element analysis software ANSYS of the evaluation of system carried out to verify the reliability of the products, ensure the product safety performance to meet customer requirements at the beginning of the design.Finally, in the accumulated more than a year after technical improvement, through experiment data statistics and comparison, significantly improve the yield of the aluminium wheel, reduces the company’s internal and external quality cost;Testing equipment of automatic upgrade to save the company’s labor costs, become benchmarking is applied in the group of companies. |
