The elevator to heavy powder forging production line is mainly composed of a 30MN cold press forming servo hydraulic press,medium frequency induction heating furnace,a 45MN hot forging forming ser-vo hydraulic press and surrounding auxiliary facilities.The two hydraulic press bodies adopt the closed structure of laminated steel plate welding,supplemented by the original X-shaped guide rail as the slide guide.The machine has high stiffness,strong anti-bias load ability and good precision retention.The main working cylinder adopts the cylinder moving plunger cylinder structure for reverse installation,which mini-mizes the press surface size,reduces the fuselage size and reduces the floor area.The plunger return cylin-der is rationally arranged in the space on both sides of the fuselage,compact layout and efficient use of space.In view of the high compression ratio and low forming force in the initial stage of pressing forming,a novel control is developed.The accumulator power supply circuit controlled by the auxiliary loop and the proportional flow valve can improve the pressing speed of the slide block to improve the production efficien-cy of the whole production line.
