大直径薄壁超声锯管机的设计研究

Design on a Supersonic Sawing Machine Used for the Thin Wall Pipe with a Large-diameter

通过对超声振动锯削过程中切削力的变化特性、超声锯削振动频率的分析研究 ,建立了超声振动锯削管材动力学模型 ,研究设计了大直径薄壁超声锯管机 ,并对超声振动频率对切削力大小、下料质量及锯条使用寿命等有关技术参数进行了试验研究 ,为大直径薄壁管件下料探索了一条新途径。

It is difficult for the sawing machine to cut the thin wall pipe with large-diameter. The paper describes the mechanism of supersonic vibration sawing process, sets up its dynamic equation, shows how to design the large-diameter thin wall pipe and the result of some experiments.
