Abstract
本发明公开了一种连续式液压成型设备及其自动控制方法。该设备除了包括油箱、溢流阀、单向阀、换向阀、单向调速阀、上油缸、下油缸、上压杆以及下压杆外,还包括电子尺、接近开关与PID调节器,电子尺的滑动端与上压杆的固定端相连接,通过将对应位置的电阻值转换为电流信号传送至PID调节器,根据预设的上压杆位移-时间曲线,PID调节器向上压杆单向调速阀输出电流量,调节阀门开度,实现上压杆的进动速度自动变化;另外,本发明连续式液压成型设备采用可编程序控制器作为整个成型过程连续运行的控制器,实现了物料装填、压制成型、毛坯取出等全过程自动连续运行,是一种结构简单、自动化程度高、无需通过手动调节上压杆的进动速度的液压成型设备
