液压胀形是一种先进的成型方法,它具有工序少、节约金属、生产率高、成型质量好和胀形压力易控制等优点,可成型形状较复杂的零件。液压胀形是近年来受国内外较重视的一种成型技术,在国外已被用于冶金、机械、石油化工、轻工、汽车、船舶和建筑等工业中。我国对液压胀形技术的研究和应用较少,虽然有些单位进行过工艺试验,多数是在普通的机械压力机上进行的,专用的胀形液压机却很少。由于受设备质量的影响,液压胀形技术
Hydraulic bulging is an advanced forming method, it has the advantages of fewer processes, metal saving, high productivity, good forming quality and easy to control bulging pressure, forming more complex shape parts. In recent years, hydraulic bulging is a kind of molding technology that has been paid more attention at home and abroad. It has been used abroad in metallurgy, machinery, petrochemical industry, light industry, automobile, shipbuilding and construction industries. China’s hydraulic bulging technology research and application of less, although some units have been tested in the process, most of them are carried out in the ordinary mechanical presses, special bulging hydraulic machine is rare. Due to the quality of the equipment, hydraulic bulging technology
