Digital hydraulic drive control system for multi direction and isothermal forging
The advantages of multi direction forging include: can make complex structure shape forging and improve the mechanical properties, the mould has the advantages of simple structure, long service life, low manufacturing cost, convenient use and maintenance, mold cooling and lubricating effect good, therefore, in aviation, petroleum, chemical industry, automobile and tractor manufacturing, atomic energy industry, concerned with the hollow frame body, a piston, a shaft cylindrical pieces, large valve, pipe fittings, landing gear, engine casing, shaft disc assembly and other forging, have begun to use multi die forging process for the production. With the maturity of the die forging technology, the forging is developing towards the fine direction, and the multi direction forging can almost certainly be the future trend of the development of the die forging.
However, the hydraulic and control technology of multi direction forging has been monopolized by a few countries in foreign countries, which restricts the development of the technology in our country. Digital hydraulic transmission and control technology not only broke the restriction of foreign technology to China, micron motion control ability, the ultra high voltage (65mpa) large flow (10000 liters / min) characteristics, simple system structure and relatively low cost, the innovation and the development of multi die forging has gained strong momentum.
Digital hydraulics is the most powerful source of innovation in the forging industry.
