Embodiment

[0061] Punching the 6061 aluminum alloy hot-rolled plate into a disc-shaped blank with a size of Φ350×65mm;

[0062]Preheat the disc-shaped blank to 490°C;

[0063] Before the forging work, preheat the forging die to 480°C, separate the upper die from the lower die, spray lubricant on the working surface of the forging die, put the preheated disc-shaped blank into the forging die, and use the forging press Forging at a speed of 20mm / s once to make a disc-shaped blank, so that the wheel hub is initially formed into a disc shape; immediately put it into water for quenching after forging;

[0064] Put the quenched disc-shaped blank into the spinning machine for strong spinning to form a hollow rotating body hub blank; then put the hub blank into an aging furnace and heat it to 175°C and keep it warm for 8 hours; finally, machine the hub blank and follow up the surface processing to obtain automotive aluminum alloy wheel products.

Abstract

The invention discloses a manufacturing method of an Al-Mg-Si alloy hub. The manufacturing method of the Al-Mg-Si alloy hub comprises the following steps of 1 manufacturing an Al-Mg-Si alloy hot rolled plate into a wafer-shaped blank; 2 pre-heating the wafer-shaped blank to 450 DEG C-500 DEG C; 3 performing hot forging on the wafer-shaped blank at the temperature of 450 DEG C-500 DEG C to form a disc-shaped blank; 4 performing quenching treatment on the disc-shaped blank subjected to the hot forging; 5 performing powerful spinning on the disc-shaped blank subjected to the quenching treatment through a spinning machine to form a hollow rotating body hub blank; 6 putting the hub blank formed through spinning into an aging furnace to be heated to 120 DEG C-220 DEG C and keeping the temperature for 2-8 hours; 7 performing machining and surface treatment. The manufacturing method can improve the aluminum hub strength, keep good plasticity, achieve energy consumption and achieve the purposes of reducing the energy consumption and improving the production efficiency.

Description

technical field [0001] The invention relates to a method for manufacturing a wheel hub, in particular to a method for manufacturing an Al-Mg-Si alloy 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 manufacturing and are widely used....
