2022-04-24
In recent years, domestic large-scale free forging has been in a period of rapid development, especially in 2006, a large-scale free forging equipment investment and construction upsurge was set off all over the country, and large-scale free forging hydraulic presses were launched one after another. According to incomplete statistics, in the two years from 2007 to 2008, there were as many as 5 free forging hydraulic presses with more than 6000 tons to be put into production, while the planned investment and construction reached more than 10. At present, the number of large-scale free forging hydraulic presses in China has ranked first in the world. Does China's free forging industry really need so many large-scale equipment? Is the entire free forging industry in short supply or in excess of demand? Is the investment in free forging equipment blind at this stage...... As early as in 1934, after the Japanese invasion of Northeast China, in Shenyang, Dalian set up machinery factory installed 20MN, 40MN free forging hydraulic press to produce large forgings. After the defeat of Japan in 1945, the forging equipment was removed by friendly forces. By the Chinese own design and manufacture of free forging hydraulic press and the production of large forgings is not long, only 50 years of history. Now review the history of the design and manufacture of free forging hydraulic press and the production of large forgings in China, it is basically divided into the following stages. (Note: When the emulsion and water used in the free forging press are the working liquids, they are called the free forging hydraulic press; when the mineral oil is the working liquid, they are called the free forging hydraulic press, collectively referred to as the free forging hydraulic press. Most of the forging presses imported or manufactured in China before 1990 used emulsion and water as the working liquid. After 1990, the working liquid of the forging press made in China is emulsion and water, and mineral oil is also useful, but most of the imported free forging hydraulic press uses mineral oil. When it is not clear that the free forging press is using that kind of working liquid, it is collectively referred to as a hydraulic press).
