超声波技术在金属探伤、零件清洗、磨削和机械加工等方面得到了应用。把超声波技术用于金属冷挤压成形也取得了明显的效果,尤其超声波拉丝已用于工业生产。在冷深冲压、压平、卷边和拉丝等成形加工中,用超声波对被加工金属进行辐射,可使加工能量减少50％以上,使不易冷挤压成形的工件, Ultrasonic technology in metal detection, parts cleaning, grinding and machining has been applied. The use of ultrasonic technology for metal cold extrusion also achieved significant results, in particular, ultrasonic wire drawing has been used in industrial production. In the cold deep drawing, flattening, curling and drawing and other forming process, the metal is processed by ultrasonic radiation, the processing energy can be reduced by 50% or more, so difficult to cold extrusion forming the workpiece,
