牛角芯棒热推弯管成形过程受力变形特点

THE CHARACTERISTICS OF FORCE AND DEFORMATION IN FORMING PROCESS OF HEATED PUSHING CURVED TUBES THROUGH OX-CORE

  • 摘要: 通过实验研究分析了牛角芯棒热推弯管成形过程瞬时应力、应变状态及其演化过程,阐明了弯管成形时的受力、变形特点,为牛角芯棒热推弯管成形过程塑性分析奠定了基础.

     

    Abstract: The forming process of heated pushing curved tubes through an ox-core, including its temporal state of stress and strain and their evolution process is analyzed experimentally, the characteristics of its force and deformation are obtained, which may serve a foundation for its plastic analysis.
