The Improvement of Control Methods for Small and Medium-Sized Hydraulic Forging Machine

Abstract

The hydraulic transmission control system in the metal forming equipment makes the piston rod freedom movement. This paper introduces that using PLC but not original relay contact to realize the free movement of the piston rod. Adopting PLC as the control system, the automation degree of the piston rod will be improved. And also ensure the piston rod has a high reliability when it has continuously acting, the system will meet the requirements of the general and flexibility. This paper analyzes the action of the hydraulic system. Subsequently, the methods of the hardware selection and the software program design were illustrated.
