当在压机上进行较大压缩量的锻造时,或者锻造的材质较脆时,用一般的方法进行锻造不可能不迂到困难,例如在坯料的边缘产生裂纹。现介绍一种新型压机,该压机有一高压室,坯料放置在高压室内,使坯料的自由表面承受着几千巴的静液压力,在这种条件下进行锻造可避免出现裂纹。 When forging is carried out on a press at a relatively large amount of compression, or when the forging material is brittle, it is not possible to forge the forging with the usual methods, such as cracking at the edges of the blank. A new type of press is described which has a high pressure chamber in which a blank is placed in a high pressure chamber so that the free surface of the blank is subjected to a hydrostatic pressure of a few thousand bar and forging is avoided under such conditions.
