METHOD OF PREVENTING CRANK-OPERATED PRESSES OVERLOAD BY FORCE AT SLIDE Russian patent published in 2011 - IPC B30B15/28

Abstract RU 2427466 C1

FIELD: process engineering.

SUBSTANCE: invention relates to press forging and may be used at crank-operated presses with composite foundation tied by studs. With force at press slide exceeding rated magnitude, reduced is rigidity of press power structure formed by press actuator, deforming tool and processed article. Note here that studs used to tie composite foundation feature central part diameter that provides reducing power structure rigidity to magnitude making 10-30% of press effective rigidity.

EFFECT: long-term inertialless protection against overloads at whatever deformation rates.
