It is desired to operate the pneumatic cylinder below which has to pistons A and B to stamp the die D. The piston A s returned in its back stroke by a spring, and has quick return. It is advised to use solenoid and pilot valves DCV . ( best design is to use two DCV valves ) 1- Make a complete circuit layout to operate the device above, using the appropriate symbols. 2-Describe in details how your system works ( typed ) 3- Names the components of your system. 4- Any pneumatic working design will be considered as correct. Piston A Return spring Gates to pilot DCV Gates from main DCV Piston B Stamped Die D
Design a hydraulic circuit to make a double-acting cylinder move forward and back when a hand-operated valve is switched on. The cycle must continue until the hand-operated valve is switched off manually. Note: The pump circuit must be safeguarded so that there is always connection between P and T line.
