Abstract
PURPOSE: To prevent the vibration produced on the press at the time of forging from being transmitted outside and thereby to prevent noise pollution, by adopting an elastic structure between the bottom surface of the liquid-pressure press proper and the upper surface of the base.
CONSTITUTION: Air spring 1 is placed between the bottom surface of the press proper and base 4 Crosshead 10 is lowered by sending high-pressure water to main cylinder 13 via piping 12. Forging object 14 is forged and processed by means of upper anvil 9 and lower anvil 8. At this time, vibration is produced on the press proper, bu it is not transmitted to base 4 because of the presence of air spring 1. Since there is the danger that the piping may be damaged by this vibration, swivel- joint 2 is placed in the mid-section of the piping
