DEVICE FOR TIGHTENING SECTIONAL PRESS BED AND ELIMINATING ITS OUT-THRUST Russian patent published in 1995 - IPC

FIELD: press-forging machinery. SUBSTANCE: seals can be replaced in one or two plunger cylinders without relieving the tightening force from the press bed since said tightening force will meanwhile be ensured by fixing it with gaskets disposed between said bed and nut body under the other cylinders. Besides, the device can be tested for tightness outside of the press by feeding pressure into the cylinders and holding them under the preset pressure since at this moment the plunger collars will bear against the end surfaces of recesses. EFFECT: improved operating conditions and higher reliability of press. 3 cl, 3 dwg
