金属超声振动塑性成形具有低能耗、降低变形力和提高产品质量等优点。文章设计了一套用于研究纯钛TA1板材在超声振动下成形性能的试验装置,并对纯钛TA1板材进行拉伸试验,测定不同超声振动功率和频率下纯钛TA1的力学性能。结果表明,超声激振作用能有效降低材料的流动应力和屈服强度,且较低频率、大功率的超声振动更有利于提高TA1的成形性能,可应用于纯钛TA1超声振动塑性成形中,提高成形效率和产品质量。
Metal ultrasonic vibration plastic forming with low energy consumption, reduce deformation and improve product quality advantages. In this paper, a set of experimental apparatus was designed to study the formability of pure titanium TA1 under ultrasonic vibration. Tensile tests on pure titanium TA1 were carried out to determine the mechanical properties of pure titanium TA1 under different ultrasonic vibration power and frequency. The results show that ultrasonic vibration can effectively reduce the flow stress and yield strength of the material, and lower frequency and high power ultrasonic vibration is more conducive to improve the formability of TA1, can be applied to pure titanium TA1 ultrasonic vibration plastic forming, increased Forming efficiency and product quality.
