根据轧制时体积不变条件和环件轮廓近似为圆的假设,推导验证了环件径轴向轧制时的导向辊运动公式,并将其用于基于Deform-3D的环件径轴向轧制模拟时的导向辊设置。结果表明:以此公式设置导向辊约束时,轧制过程比较稳定,环件内径及外径的椭圆度均较小,环件成形良好。 Based on the assumption that the volume invariance and the profile of the ring are approximately round during rolling, the formula of the guide roller motion during the axial rolling of the ring is validated and used in the radial direction of the ring based on Deform-3D Guide roller setting during rolling simulation. The results show that the rolling process is relatively stable with the guide roller constraint set by this formula, and the ellipticity of the inner diameter and the outer diameter of the ring is small, and the ring shape is good.
