Embodiment

[0075] Take a 22.5-inch automotive aluminum alloy wheel as an example:

[0076] The 5083 aluminum alloy hot-rolled plate is punched into a ring-shaped blank with an outer diameter of Φ800mm and an inner diameter of Φ260mm;

[0077] Preheat the ring-shaped blank to 380°C, spin and draw it into a disc shape;

[0078] Put the cooled disc-shaped blank into the forging die, and use the forging press to cold forge the spoke part;

[0079] Heat the forged aluminum alloy wheel blank to 150°C, and spin the forged aluminum alloy wheel blank on the spinning machine to form a hollow rotating body hub blank;

[0080] Then the hollow rotating body hub blank is kept in a continuous annealing furnace at 200°C for 1 hour; finally, the hub is machined and followed by surface treatment to obtain an automotive aluminum alloy hub product.

[0081] The aluminum alloy wheels obtained in the above examples were selected for corresponding mechanical performance tests, and samples were taken at diffe...

Abstract

The invention discloses a manufacturing method of commercial high-magnesium aluminum alloy wheel hubs. The manufacturing method includes the following steps that 1 raw materials of high-magnesium aluminum alloy hot rolled plates are made into annular blank; 2 a spinning machine or a punching machine is used for drawing the annular blank into the shape of a disc, and disc-shaped blank is obtained; 3 the disc-shaped blank which is cooled to the temperature below the re-crystallization temperature is placed into a forging and pressing mould, a forging and pressing machine is used for forging and pressing spoke portions, and forged and pressed aluminum alloy wheel hub blank is obtained; 4 on the spinning machine, the forged and pressed aluminum alloy wheel hub blank is spun into hollow rotating body wheel hub blank; 5 the hollow rotating body wheel hub blank formed through spinning is placed in the environment at the temperature of 100 DEG C-250 DEG C for 0.5-6 hours, and low-temperature stabilizing treatment is achieved; 6 machining and surface treatment are conducted. According to the manufacturing method, the problems that an existing technology is complicated, low in production efficiency and high in energy consumption are solved, and the purposes that energy consumption is reduced, the production efficiency is increased and products have good mechanical properties are achieved.

Description

technical field [0001] The invention relates to a method for manufacturing a wheel hub, in particular to a method for manufacturing a high-magnesium aluminum alloy commercial wheel hub. Background technique [0002] At present, the automobile industry is developing in the direction of light weight, high speed, safety, energy saving, comfort and low environmental pollution, so the amount of aluminum alloy parts used in automobiles is increasing day by day. As one of the important parts in the driving system of the car, the wheel hub is also a kind of security device with high requirements. It not only bears the weight of the car, but also reflects the appearance of the car. In the past ten years, the average annual growth rate of the global aluminum alloy automobile wheel production has reached 7.6%. It can be seen that with the increasing demand for lightweight automobiles, aluminum alloy wheels are gradually replacing traditional steel wheels in modern automobile manufactu...
