Development of Control System of Electro Hydraulics Servo Leaf Spring Mill
The electro hydraulics servo tape leaf spring mill is a special equipment used to manufacture automobile tape leaf spring. The structure of main body of mill is adopted four-column type. The roll gap of mill is driven by the servo hydraulics cylinder. The type of two degree computer control system, composed by microcomputer and PLC, has been adopted in this mill. The movement control requirement of the mill for manufacturing tape leaf spring has been analyzed The structure characteristic and forming principle of the electro hydraulics servo control system of the mill has been introduced. The control programs for rolling leaf spring and digital PID had been designed for having accomplished the automatic control of roll gap for tape leaf spring and precision indemnity. The precision and efficiency requirement of all type of leaf spring at home and abroad to the mil has been satisfied.
