| 摘 要： | 为促进超声振动拉丝的实际应用,针对不同施振方式的作用效果,建立了一套正交复合超声振动拉丝实验系统,系统由超声波驱动器、超声振动系统、拉丝模和拉丝机等组成.利用有限元法对正交复合超声振动拉丝进行仿真模拟,分析超声振动拉丝的加工机理.通过对铜丝的一系列拉拔实验,考察了在实际拉丝加工过程中,纵向振动、横向振动和正交复合超声振动对拉拔力和丝表面质量的影响.实验结果表明:当振幅达到一定值后,正交复合超声振动的作用效果最好,能使拉丝机的张力调节周期有效延长3倍以上,减少了丝材的不均匀变形,使拉丝更趋于稳定;当拉拔速度为980 mm.s-1时,可使拉拔力减小近10%,改善了丝材表面质量.
