Problems solved by technology

[0004] At present, most of the aluminum alloy wheels produced by various manufacturers use forging technology to process them into rim-spoke integrated wheels. The forging lines for the production of aluminum alloy wheels are ordinary CNC lathes with belt drive, three-jaw sector fixtures, and carbide blades; The manufactured aluminum alloy wheels are generally whitish in appearance, with cable burrs on the surface, and the finish is very low, which affects the overall beauty and market value of the wheel; it cannot open the market well and improve the beauty and value of the vehicle

Embodiment 1

[0022] Embodiment 1: A kind of processing technology of aluminum alloy wheel with high finish, the process steps are as follows:

[0023] S1. Selection of aluminum alloy bar material, select aluminum alloy bar material with suitable material and size; aluminum alloy bar material meets the first-grade grain size homogenization hydrogen content <0.25ml / 100g, diameter 200-280mm, total length 5500-6500mm ;

[0024] S2. Aluminum alloy bars are prepared and cut with a CNC high-precision sawing machine cutting machine;

[0025] S3. Heating the aluminum alloy bar material, heating the aluminum alloy to a certain temperature within a certain period of time; generally heating the aluminum bar to about 500°C within 6 hours, and at the same time heating the mold to above 350°C in the mold furnace for standby;

[0026] S4, the pre-forging process, using a hydraulic forging machine and a pre-forging die to thicken the heated aluminum alloy bar to produce a bowl-shaped pre-forging;

[0027...

Embodiment 2

[0036] Example 2: Select the mirror lathe according to the size of the wheel. It is required that the X-axis processing range reaches a diameter of 750 mm and the Z-axis processing range reaches 850 mm. The ball screw directly connected to the AC motor is selected, and the accuracy is controlled within 0.002 mm. The machine tool adopts gear transmission to avoid rotation speed. Loss, install the machine tool to do 40-50cm anchor bolts to reduce the vibration when the machine tool is working.

[0037] Choose a 22.5-inch self-centering pull-arm fixture according to the size of the wheel. When the rotary cylinder of the machine tool is working, the three pull-arms generate a downward pressing force (6-8MPa), and anti-scratch nylon pads should be installed on the pull-arms. The center of the fixture is equipped with a retractable positioning device, which is positioned through the center mounting hole of the wheel, and the accuracy is controlled within 0.02mm. When the machine too...

Abstract

The invention provides a high-smooth-finish aluminum alloy wheel machining process and relates to the technical field of aluminum alloy wheels. The high-smooth-finish aluminum alloy wheel machining process approximately comprises the following steps of: selecting aluminum alloy rod materials; preparing the aluminum alloy rod materials; heating the aluminum alloy rod materials; carrying out a pre-forging step; carrying out a molding forging step; carrying out a flaring forging step; carrying out a spinning stretching step; carrying out a thermal treatment step; carrying out a rough machining step by using a lathe; and machining a centre-drilling hole, wherein a mirror lathe is used; a cutter on the lathe is an artificial diamond PCD cutter; and a clamp used is a pull arm type self-centeringclamp. Compared with the prior art, the high-smooth-finish aluminum alloy wheel machining process provided by the invention has the beneficial effects that the surface smooth finish of an aluminum alloy wheel manufactured by the process provided by the invention is as high as Ra0.8; an excellent surface light reflection effect is achieved; the aluminum alloy wheel is brighter and more beautiful in overall effect; meanwhile, the effect that saw teeth remaining in cutting of the cutter is also effectively eliminated; and the service life of the wheel is prolonged by 15% to 20%.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy wheels, in particular to a process for processing high-gloss aluminum alloy wheels. Background technique [0002] The wheel is a load-bearing rotating component between the tire and the axle. It usually consists of two main components, the rim and the spoke. The rim is the part used to install and support the tire on the wheel. The supporting part of the rim connection. [0003] With the development of science and technology, commercial trucks and passenger vehicles are developing in the direction of light weight, more comfortable driving, lower fuel consumption and more beautiful appearance; the demand for light weight and beautiful appearance has promoted the application of aluminum alloy materials in the wheel industry. Various aluminum alloy materials and their production processes have been greatly developed on wheels. [0004] At present, most of the aluminum alloy wheels produced b...
