|Hydraulic presses are used in many industrial technologies. Press application include forging pressure with flat dies, used for hot work to break down ingot and shape them into roll, pressure vessel, forged bar ,rods ,plates and so on. Forging presses with closed dies, used to process preheated billet into various shapes. Upsetting presses, used for production of items with elongated shaft-long hollow bushings, pipes, vessel and so on.
The paper describes the hydraulic system for the 15000 ton capacity with the selection of hydraulic component, development of hydraulic circuit and pumping requirement i.e. amount of fluid handled by the pumps and the size of accumulator etc.
Paper describes the complete process, principles and component of the forging press with their arrangement in system by the hydraulic circuit diagram development from lower capacity to desired one. It is developed by considering requirement of the process. Further part of the paper contains the design procedure and calculation for the process and the analysis of main ram considering the given requirement and calculation results.
