Large and difficult to deform forgings in the manufacturing process have to go through the free forging billet,die forging or isothermal forging molding.This multifunctional hydraulic press is mainly facing the aviation,aerospace,military and other fields of high-end forging forming,as well as for small quantities,customized products and specially designed forging hydraulic press.This paper is mainly from the mechani-cal structure of the equipment to take into account the die forging isothermal forging free forging heavy-duty multifunctional hydraulic presses for the elaboration and for the combination of the two processes of the main design ideas.Through the introduction can be used as a design reference to provide designers with some specific ideas,but also for 10,000 tons of forging equipment to provide some data support and the corresponding design advice.
