一、概述振动时效是一种新的时效方法,它较之热时效具有成本低、燃料省、生产周期短、生产率高、设备简单、易于操作等特点,而且,这种工艺不仅可以用来处理铸、焊、锻等黑色金属件,也可用于有色金属件。对于那些不能进行热处理或炉容量不够的大型零件更具有独特的作用。在国外自40年代就着手研究。起先在德国、法国、苏联采用此法,以后美国、日本相继采用。国内进入70年代以来,北京机床所、大连机床厂等单位先后开展了这方面的理论研究和生产应用,取得了大量的数据和明显的经济效益。数据表 I. Overview Vibration aging is a new aging method, which has advantages of low cost, fuel saving, short production cycle, high productivity, simple equipment and easy operation compared with thermal aging. Moreover, this kind of technology can not only be used for processing Casting, welding, forging and other ferrous metal parts, can also be used for non-ferrous metal parts. For those who can not be heat treatment or furnace capacity of large parts have more unique role. In foreign countries since 40 years to start research. First in Germany, France, the Soviet Union to adopt this method, after the United States, Japan have adopted. Since the 70s into the country, Beijing Machine Tool Plant, Dalian Machine Tool Plant and other units have conducted theoretical research and production applications in this area, and made a lot of data and significant economic benefits. data sheet
