摘要：

传统的由自由锻造液压机生产的棒料在三点反弯校直过程中不仅费时、费力，而且校直精度低。针对此问题，基于非接触测量方式，提出一种20 MN C型全自动校直机。通过安装在校直机主机内的二维激光位移传感器，对棒料进行自动测量。根据测量数据计算棒料弯曲参数，确定弯曲形状。最后，基于弹塑性变形理论，建立校直过程中的载荷-挠度（F-δ）关系，并计算校直工艺参数，从而实现棒料的连续检测和自动校直。

Bars produced by the traditional free forging hydrauic press have deficiencies of time-consuming, laborious and low alignment accuracy in three-point reverse bending alignment process. For the above problems, a kind of 20 MN C type automatic straightening machine was put forward based on the non-contact measurement, and the bars could be measured automatically by the two-dimensional laser displacement sensor installed in the straightening machine. Then, the bars bending parameters were calculated according to the measuring data, and the bending shape was confirmed. Finally, the F-δ relationship was established in the alignment process, and the straightening process parameters were calculated to achieve a continuous detection and automatic straightening of the bar based on the elastic-plastic deformation theory.
