芯辊进给速度对T形环约束轧制成形的影响

Effect of Feed Speed of Core Roller on T-ring Constrained Rolling Forming

T形环在轧制成形过程中金属流动复杂,截面充填困难。本文利用有限元模拟软件ABAQUS对T形环约束轧制成形过程进行了模拟,得到了不同芯辊进给速度时T形环的等效应变分布、截面充填、轴向宽展以及轧制力变化规律,进而揭示了芯辊进给速度对T形环约束轧制成形的影响规律。

The metal flow in rolling forming process of T-ring is complex and the cross-section filling is difficult. The forming process of T-ring constrained rolling was simulated by using the finite element simulation software ABAQUS. The equivalent strain distribution, cross-section filling, axial spread and rolling force variation of T-ring with different feed speed of core roller were obtained. And the influence of feed speed of core roller on the constrained rolling forming of T-ring was revealed.
