The importance of aluminum alloy forging production

Forging production is one of the main ways to provide blanks of mechanical parts to various industries. The superiority of forging production lies in: it not only obtains the shape of mechanical parts, but also improves the internal structure of the material and improves the mechanical properties. Generally speaking, most important mechanical parts with large forces and high mechanical performance requirements are manufactured by forging methods.

Due to a series of advantages such as small specific gravity, specific strength, and high specific rigidity, aluminum alloy has been widely used in various industrial sectors, and aluminum alloy forging parts have become an indispensable material for mechanical parts in various industrial sectors. All kinds of forgings that can be forged from low-carbon steel can be forged from aluminum alloy. Aluminum alloy can be forged on various forging equipment such as forging hammers, mechanical presses, hydraulic presses, upsetting machines, reaming machines, and can be forged freely, die forging, roll forging, upsetting, roll forging and reaming.

Generally speaking, aluminum forgings with small size, simple shape, and low deviation requirements can be easily forged on a hammer, but for aluminum forgings with large specifications and severe deformation, water (liquid) presses should be used. forging. For large and complex aluminum forgings with integral structures, large-scale die forging hydraulic presses must be used to produce them. For large precision ring parts, it is advisable to use a precision ring rolling machine for rolling and forging. Especially in the past ten years, with the progress of science and technology and the development of the national economy, higher and higher requirements have been put forward for materials, forcing aluminum alloy forgings to develop in the direction of large-scale integration, high-strength, high-toughness, and complex precision. Promoted the development of large and medium hydraulic presses and ring forging machines.

With the development of China's transportation industry in the direction of modernization and high-speed development, the requirements for lightweight transportation of transportation tools are becoming stronger, and the call for replacing steel with aluminum is increasing, especially for aircraft, spacecraft, and railway vehicles with high requirements for lightweight. , Subways, high-speed trains, freight cars, automobiles, ships, ships, artillery, tanks, machinery and equipment and other important force-bearing parts and structural parts. In recent years, a large number of aluminum and aluminum alloy forgings and die forgings have been used to replace the original steel structural parts. For example, almost all aircraft structural parts are made of aluminum alloy die forgings; automobile (especially heavy-duty vehicles and large and medium-sized passenger cars) wheels, bumpers, and base beams; tank wheels; turret frames; helicopters moving and stationary rings; The cylinders and piston skirts of trains; the fuselage of woodworking machinery; the bases, tracks and stranding reels of textile machinery have all been manufactured using aluminum alloy die forgings. Moreover, these trends are increasing substantially, and even some aluminum alloy castings have begun to be replaced by aluminum alloy die forgings.

At present, there are few large forging hydraulic presses in the world, and China is even rarer. With the modernization of the defense industry and the development of the civil industry, especially the transportation industry, the variety and output of aluminum alloy die forgings cannot meet the needs of the domestic market. , There is also a big gap in the international market. Therefore, it is very necessary and timely for China to build several large and medium-sized aluminum alloy forging production lines. It has important practical and long-term significance for the rapid development of the national economy and the modernization of national defense and military industries.

Since the reform and opening up, China has vigorously strengthened its economic construction and the continuous development of industry has become the main driving force of China's economic development. The forging industry can be said to be an important part of modern industry. With the development of modern technology, China's forging industry technology is also constantly developing. For example, the flexibility control of the forging industry has basically entered the automation stage. Its process technology applications are becoming more and more extensive, not only involving the aviation and automobile industries, but also the home appliances and electronics industries, and they have become the economic pillar industries of many countries. Of course, China is no exception. The forging industry also plays a pivotal role and position, and has a significant impact on the development of China's national economy.
