高速成形是金属压力加工技术中最新的成就之一。目前,它有四种基本形式:即爆炸成形、液电成形、电磁成形和气动高速锤成形。气动高速锤以往只加工航空工业用的“特殊合金”以及耐热材料,而目前已用来加工一般锻件。用这种方法锻成的另件,一般来说,精度较高,只需经过少量机械加工;或不需机械加工。 High-speed forming is one of the latest achievements in metal pressure machining. Currently, it has four basic forms: explosion forming, liquid forming, electromagnetic forming and pneumatic hammer forming. Pneumatic high-speed hammer in the past only for the aviation industry with the “special alloy” and heat-resistant materials, and has now been used to process the general forgings. In this case, forged parts, in general, have higher precision, requiring only a small amount of machining, or machining without machining.
