Large-scale aluminum alloy hub isothermal forging production line

Abstract

The invention relates to a large-scale aluminum alloy hub isothermal forging production line. The large-scale aluminum alloy hub isothermal forging production line is characterized by comprising a bar cutting machine, a bar heating furnace, a plurality of delivery manipulators, a pre-forging hydraulic press, a hub finish-forging hydraulic press, an aluminum alloy hub broaching and trimming hydraulic press and a pressing die. A cold material conveying roller table is arranged between the bar cutting machine and the bar heating furnace, a hot material conveying roller table is arranged between the other end of the bar heating furnace and the delivery manipulators, a die heating furnace, a die change trolley and a change trolley rail are arranged on one side of the pre-forging hydraulic press, a pre-forging lubrication spraying device is arranged on the other side of the pre-forging hydraulic press, a middle heating furnace or a delivery roller table is arranged between each two manipulators, and a finish-forging lubrication spraying device is arranged on one side of the hub finish-forging hydraulic press. The large-scale aluminum alloy hub isothermal forging production line has the advantages that by means of structural and technical combination of hot die forging, broaching and trimming, one-time pressing of aluminum alloy hubs can be realized, the pressing process of the aluminum alloy hubs is simplified, cost, time and labor for later-stage secondary processing and shaping can be greatly saved, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of forging machinery, in particular to an isothermal forging production line for large aluminum alloy wheel hubs. Background technique [0002] As one of the most important moving parts of a car, the wheel hub has high requirements on its performance, weight and service life. In recent years, due to its advantages of light weight, fast heat dissipation, good shock absorption performance, long life and good balance, aluminum alloy wheels stand out in the automotive industry and are widely used in various new models. At present, the methods of manufacturing aluminum alloy wheels at home and abroad are mainly divided into two categories: one is forging method, among which, the most advanced foreign technology is composed of continuous casting process and three forging processes. Although the quality of this method is good, the finished product The rate is only about 50%, and the price is expensive. The other is the cas...

Problems solved by technology

Because this substance is very easy to produce smoke and toxic and harmful gases, it has a toxic effect on the human body. Operators need to wear protective masks when operating. However, because the surrounding environment has been polluted by release for a long time, the protective masks are only simple protection and cannot be used. To achieve the real protection of workers' health, in many cases, this kind of environmental pollution has caused great harm to the health of operators

[0007] To sum up, the use of traditional casting or forging equipment can no longer meet the needs of high production efficiency and lower operating costs, so a large-scale aluminum alloy wheel isothermal forging production line is needed to meet the production and manufacturing process of aluminum alloy wheels
