一种基于椭圆度动态检测的碾环机椭圆度控制方法及系统
By using a ring rolling mill control method based on dynamic ellipticity detection, data is collected in real time using a laser rangefinder and a main roll encoder, and the compensation amount of the core roll is automatically adjusted. This solves the ellipticity control problem caused by manual visual inspection and improves the processing efficiency and forming quality of large ring parts.

AI Technical Summary
Technical Problem
In the rolling process of large metal rings, ellipticity control relies on manual visual inspection, resulting in poor forming quality and serious waste of materials and energy.
Method used
A ring rolling mill control method based on dynamic ellipticity detection is adopted. Data is collected in real time through a laser rangefinder and a main roller encoder to calculate the ring radius and ellipticity, automatically adjust the core roller compensation amount, and establish a closed-loop control process.
Benefits of technology
It improves the processing efficiency and forming quality of ring parts, reduces the scrap rate of ring parts caused by excessive ellipticity, and reduces material and energy waste.

Abstract
本发明涉及碾环机技术领域，尤其涉及一种基于椭圆度动态检测的碾环机椭圆度控制方法及系统，包括：激光测距仪实时采集环件测量点i的激光距离，获取环件测量点i的环件壁厚，主辊编码器获取环件测量点i的弧度坐标；计算得到环件外径、环件内径、环件中径；计算得到每一环件测量点i的环件半径、原始参考半径、有效半径；计算得到环件的长半轴长度和短半轴长度，进而计算椭圆度；判断椭圆度是否符合设定值，若不符合，计算芯辊补偿量，执行径向补偿动作；循环执行上述步骤，直至环件按预设的直径增长及高度壁厚加工程序完成加工。本发明提高了环件的加工效率和成形质量。
