振动时效是—种新的时效方法。该工艺的研究表明,它在降低构件残余应力和提高精度稳定性上均为30～50％。经过试验,振动时效完全可以取代压缩机制造中消除大件加工应力的热时效工序,从而取得良好的技术经济效果。 Vibration aging is - a new method of aging. The study of the process shows that it is 30 ~ 50% on reducing the residual stress of the component and improving the stability of the precision. After testing, vibration aging can completely replace the compressor manufacturing to eliminate large thermal stress thermal aging process, so as to achieve good technical and economic results.
