采用比例方向阀实现液压机底缸精确定位

Accurate positioning of bottom cylinder for hydraulic press by aids of proportional direction valve

此套控制系统采用可编程控制器根据磁致伸缩位移传感器反馈的位置信息实现对比例方向阀的控制,从而满足液压机底缸顶出位置的精确控制,确保制件批量制作的质量。通过触摸屏数据采样功能,可对每种工件的位置等实际参数进行存储,并可形成报表输出。

The programmable controller has been adopted in this set of control system to realize the control of proportional direction valve according to the feedback position information by magnetostrictive displacement sensor. Thus in this way, the accurate control of ejection position of bottom cylinder for hydraulic press has been satisfied, which ensures the quality of batch production. The data sampling function in touch screen has been applied to store the aetual position of each kind of workpiece and output data report.
