Abstract

The invention discloses an integral aluminum alloy spinning hub and a manufacturing method thereof. The method mainly comprises the steps of (1) selecting an aluminum alloy medium-thickness panel as an initial blank; (2), forming the middle material of the aluminum alloy panel to be a hub and pre-forming the edge material of the aluminum alloy panel to be a rim by adopting strong bending spinning; (3) splitting the preformed rim to be a rim front piece blank and a rim rear piece blank by adopting splitting spinning; (4) respectively forming the front piece blank and the rear piece blank to a rim front piece and a rim rear piece by adopting strong thinning spinning. The spinning hub produced by the process is high in material use rate, and the material is subjected to plastic deformation for multiple times and is high in strength; a workblank does not need to be precast, forged or cast, the process is simple, the machining cost is low and the production efficiency is high. The front piece and the rear piece do not need welding and screw connection and have stable mechanical performance and high safety performance.

Description

technical field [0001] The invention belongs to the field of manufacturing aluminum alloy wheels, and in particular relates to an integral aluminum alloy spinning wheel and a manufacturing method thereof. Background technique [0002] For a long time, steel wheels have occupied the dominant position in the production of automobile wheels. With the improvement of people's requirements for the safety and comfort of cars, energy saving and environmental protection, steel wheels are no longer suitable for the needs of modern cars. Wide range of applications. [0003] Compared with steel wheels, the weight of aluminum alloy wheels is reduced by about 30%-40%, which can effectively improve the rotational inertia of the wheels, make the car easy to accelerate, and reduce the energy consumption required for braking, thereby reducing fuel consumption; aluminum alloy wheels It has strong vibration absorption performance, reduces the vibration during driving, improves the center of g...
