The invention relates to a
swaging manufacturing method of a light aluminum
alloy rim. The method comprises the following
processing steps: (1) baiting; (2) heating; (3) carrying out ring rolling; (4) manufacturing a
spinning blank; (5) carrying out hot
spinning; (6) carrying out head back hot
spinning; (7) carrying out heat treatment; and (8) fine
machining the blank into a rim product. The performance indexes of the rim all reach national standards. The method only needs a pair of spinning moulds, i.e. an upper spinning mould and a lower spinning mould for
processing, wherein the moulds have simple structure, easy manufacture and low manufacturing cost. High temperature and high speed hot spinning
processing is adopted so as to ensure that the metallographic structure of the rim has uniformity, refined crystalline grain, light weight, thin thickness,
mechanical property improvement of the rim, high precision and good quality, and compared with a rim processed by cold spinning, the rim of the invention cannot crack and generate pinholes and has long service life. The blank processed by the method is annular and has high material
utilization rate, less waste and processing amount reduction. Meanwhile, the invention provides a new variety for the rims in the car accessory market. Consumers can conveniently replace and adjust the rims of different shapes and types as required atany time without dismantling a tire so as to quickly change the type of the whole tire.
