热挤压成型液压机的电液控制系统与工艺成型方法

Electrohydraulic control system and process forming method of hot extrusion hydraulic press

介绍了一种新的控制方法,采用电液控制系统对热挤压成型设备最大限度的开发使用,用PID控制方法精准控制速度,用伺服电机有效控制空载能耗,多油缸实现吨位速度切换,根据工艺成型方法,不同位置需要不同的速度和压力,合理分配压机能源。此套控制方法可以为以后热挤压成型领域的控制模式起到指导作用。

This paper introduces a new control method of the electro-hydraulic control system of equipment make maximum use of development,precise speed control with PID control method,with the effective control of the servo motor no-load power consumption,oil cylinder to realize more tonnage speed switch,based on different positions require different process speed and pressure,reasonable energy distribution of compressor.This set of control method can play a guiding role for the control mode of future extrusion field.
