Problems solved by technology

Although forged wheels have the advantages of light weight and fuel saving, the production process is complicated and the cost is relatively high. Therefore, considering the anti-oxidation function of aluminum alloy itself, forged aluminum alloy wheel manufacturers generally produce two types of surface, namely fine car and polished. Sprayed wheels, as the service life increases, the wheels in these two states reflect problems such as poor wear resistance, easy corrosion and oxidation, and short life

Embodiment 1

[0030] Such as Figure 1 to Figure 2 Shown, a kind of long-life forged aluminum alloy wheel manufacturing method comprises the following steps:

[0031] S1: Bar stock heating: 6061 aluminum bars are heated in the bar stock heating furnace for 110 minutes, and the bar stock exit temperature is 460°C;

[0032] S2: Forging: On a 6,000-ton press, the temperature of the forging die is 370°C, and the heated bar is forged in a single step to produce a round forging billet with rim legs;

[0033] S3: Punching and flaring: On the 315t press, place the rim leg of the forged billet upwards, use the flaring block to expand the rim leg to a certain angle, and at the same time punch the center of the forging billet to facilitate the subsequent spinning process forging The blank is placed on the spinning die and the blank is positioned.

[0034] S4: Cleaning and cooling: After the flaring and punching, the forged blank enters the cleaning line and is cleaned with room temperature water;

Abstract

The invention relates to the technical field of aluminum alloy wheels, and particularly relates to a manufacturing method of a long-service-life forged aluminum alloy wheel. The manufacturing method is characterized in that the surface of the wheel is strengthened by adding a wheel surface treatment process so as to obtain a forged aluminum alloy wheel with long service life, wear resistance, corrosion resistance and oxidation resistance. The manufacturing method comprises the operation steps of S1, bar heating; S2, forging, specifically, conducting single-step forging on the heated bar; S3, punching and flaring, specifically, expanding rim legs by a certain angle, and punching the center of a forging stock at the same time; S4, cleaning and cooling, specifically, putting the forging stockinto a cleaning line for cleaning; S5, spinning, specifically, placing the forging stock on a spinning lower die for compaction; S6, heat treatment, specifically, conducting heat treatment by means of solid solution, quenching and artificial aging; S7, rough turning; S8, surface roller burnishing, specifically, conducting full roller burnishing on the front surface, a back cavity and an outer side rim of the wheel; S9, drilling and window milling; S10, surface wiredrawing, specifically, conducting wiredrawing treatment is conducted on the front surface and the back cavity of the wheel; and S11, surface passivation, specifically, putting the wheel into a passivation solution for soaking, washing with pure water after passivation and then drying.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy wheels, in particular to a method for manufacturing long-life forged aluminum alloy wheels. Background technique [0002] In recent years, with the development of the automobile industry, more and more commercial trucks and buses are equipped with forged aluminum alloy wheels, which promotes the rapid development of the forged aluminum alloy wheel industry. Although forged wheels have the advantages of light weight and fuel saving, the production process is complicated and the cost is relatively high. Therefore, considering the anti-oxidation function of aluminum alloy itself, forged aluminum alloy wheel manufacturers generally produce two types of surface, namely fine car and polished. Sprayed wheels, as the service life increases, the wheels in these two states reflect problems such as poor wear resistance, easy corrosion and oxidation, and short life. Therefore, only by improving the li...
