型砂水分及铸型紧实度是砂处理过程中的重要参数。以实测的端电压U、紧实率δ以及压力传感器的位移为反馈量,与标称值比较,取偏差,调节水阀、砂供给和造型机等,对型砂水分及铸型紧实度进行检测与控制。并给出了一种基于工业以太网的监控思路,通过环网数据交换,实现上位机中型砂水分及铸型紧实度的统一监控,提高了管理效率。
Molding sand and mold compaction is an important parameter in the sand treatment process. Take the measured terminal voltage U, the compaction rate δ and the displacement of the pressure sensor as the feedback amount, compared with the nominal value, take the deviation, adjust the water valve, sand supply and molding machines, sand and moisture content of the mold and mold compaction Detection and control. And gives a monitoring idea based on Industrial Ethernet. Through data exchange in the ring network, it realizes the unified monitoring of the medium-sized sand moisture of the PC and the compaction degree of the mold, and improves the management efficiency.
