塑性加工过程中,对模具或坯料施加低频振动可以改善材料塑性,降低成形力,改善组织,使组织细密均匀,提升力学性能,提高抗拉强度,且由于低频振动功率大、技术简单,更容易实现工业化。文章揭示了低频振动式塑性加工的工作机理,分析了低频振动在理论研究和工业应用的现状,对典型低频振动塑性加工技术进行了剖析,并就低频振动存在的问题和发展进行了探讨。
Plastic processing, the mold or billet to impose low frequency vibration can improve the material plasticity, reduce the forming force, improve the organization, the organization fine uniform, improve mechanical properties and improve tensile strength, and the low-frequency vibration power, technology is simple, easier Realization of industrialization. This paper reveals the working mechanism of low frequency vibration plastic processing, analyzes the current situation of low frequency vibration in theoretical research and industrial application, analyzes the typical low frequency vibration plastic processing technology, and discusses the existing problems and development of low frequency vibration.
