Manufacturing method of light-load automobile aluminum alloy wheel hub

Abstract

The invention discloses a method for manufacturing an aluminum alloy wheel hub of a light-loaded automobile. The steps are as follows: A. Making the rim: according to requirements, select profiles of different cross-sections extruded from aluminum alloy materials, and then roll the profiles into a circle Cylinder, welding the butt joint, then rounding, and finally flanging the wheel lip; B. Spoke production: the circular aluminum plate is stretched or spun to make the aluminum plate reach the designed shape of the spoke, and then the spoke Stamping and processing various through holes; C. Manufacturing of the wheel hub: assembling the spokes in the inner circle of the rim; D. Completing the manufacturing: machining the lip parts of the wheel to complete the final manufacturing of the hub. The wheel rim in the present invention adopts the wheel rim profile that can be produced in large quantities to make the wheel rim. A large number of processing steps are reduced, manufacturing costs are saved, mass production is easier, and it can be directly entered into the ranks of low-end cars, making the promotion range of aluminum alloy wheels wider.

Description

technical field [0001] The invention relates to an aluminum alloy wheel, in particular to a method for manufacturing an aluminum alloy wheel hub for light-loaded vehicles. Background technique [0002] The rapid development of an era is destined to have a huge revolution in this era. Take the automobile wheel industry as an example, such as traditional steel wheels, in terms of production cost, steel wheels are far better than aluminum wheels. Steel wheels are mainly suitable for minivans, economical cars, small four-wheeled vehicles, etc., which are economical and practical, and are the best choice for low-end vehicles. However, with the development of the times, steel wheels have been unable to keep up with the times in terms of lightweight, environmental protection, performance, production costs, etc., and are destined to be eliminated by the times. With its excellent mechanical properties and gorgeous appearance, aluminum alloy wheels have been widely used in various m...
