Design & simulation of plc control and electro-hydraulic system for a punching machine

Abstract EN

Automatic control has become an important and integral part of modern manufacturing and industrial processes.

Automatic control provide means for attaining optimal performance of dynamic systems, improve the quality and lower the cost of production, expand the production rate, relive the drudgery of many routine, repetitive manual operations, etc..

In this paper it has been designed a control system which controlled the operation of punch machine.

As shown in Fig.

(1) this system consists of : (1) the programmable logic controller (PLC) which is used to control time and regulate the sequence.

(2) The Hydraulic system receives and implements the logical commands of PLC.

(3) Electrical interfacing circuits which are very important to compromise in the stages of system.

In order to avoid mistakes of direct design and implementation in the industrial and production processes and what follows from high material cost, therefore Automation Studio Software has been used to design the hydraulic system according to the required giving's by using Simulation software before the machine is fabricated, also it is distinguished in the simplicity of using, have a very good specification in design and the ability of exposing the parts of the system in one screen and show the connection between them, this led to have expected programmable results.
