大台面热模锻液压机运动滑块平衡状态远程监控系统

大台面热模锻液压机滑块运动受多种因素干扰,滑块工作平面容易产生倾斜,严重影响热模锻模具寿命和产品质量,需要进行实时跟踪测量并进行纠偏。针对已有大型液压机滑块平衡检测方法不足,提出基于运动滑块倾斜角的整体倾斜和下表面变形双重状态检测方法,设计适用于该方法的传感节点布局,基于ZigBee技术构建远程监控系统,实时检测运动滑块平衡状态。通过大台面模锻液压机滑块运行实验,对比远程实时检测数据和滑块的实际工作数据,监控系统通信良好,检测精度可达0.01°,表明滑块平衡状态检测方法及远程监控系统对热模锻液压机正常运行有一定参考意义。

Real-time balance state remote monitoring system of the hot forging hydraulic press moving slide with large table

The movement of slide of large table hot die forging hydraulic press is interfered by many factors. The working plane of slide is prone to tilt, which seriously affects the service life of forging die and product quality. It is necessary to conduct real-time tracking measurement and rectification. In view of the shortcomings of the exist slide balance detection methods for large-scale hot die forging press, based on the tilt angle of the moving slider, a dual state detection method of the whole tilt and the deformation of the lower surface is proposed, and designing the sensor node layout that is suitable for this method. Based on ZigBee wireless sensor network, a balance state remote monitoring system of moving slide has been presented, which can detect the balance state of the moving slide in real time. Through the operation experiment of the slide of the large table die forging hydraulic press, the comparison between the remote real-time detection data and the actual working data of the slide shows that the detection accuracy reaches 0. 01 °, The results show that the detection method of the balance state of the slide and the remote monitoring system have certain reference significance for the normal operation of the hot forging hydraulic press.
