一种行程可调压力机上死点智能校准系统

The intelligent calibration system of top dead center for stroke-adjustablepress

本文针对行程可调压力机在滑块行程调整后,上死点会发生一定的角度漂移,需要重新标定的问题,提出一种上死点智能校准的算法,只要通过触摸屏输入偏心套的调整角度,就可通过PLC计算出上死点的漂移量,并与电子凸轮通信,修改相应参数,校准上死点。本文通过现场测试验证了该算法的可行性和有效性。

Aiming at the problems that the top dead center would shift in a certain angle after adjusting the stroke in the stroke-adjustable press which need re-calibrating work, a new intelligent calibration algorithm of top dead center has been presented in the text. As long as the adjusting angle ofeccentric sleeve has been input via touch screen, the shifting amount of top dead center can be calculated through the programmable logic controller （PLC）. By communicating with electronic CAM and changing related parameters, the top dead center has been calibrated. The effectiveness and feasibility of the algorithm have been verified through site testing.
