DEVICE TO REGULATE PAD LOAD AND PRESS INCORPORATING SAID DEVICE Russian patent published in 2010 - IPC B30B15/14 B21D24/10 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and can be used in presses for adjusting load acting on press pad. Pad is arranged under the press slider. Proposed device comprises hydraulic cylinder that makes proposed press pad, hydraulic control valve communicated therewith, hydraulic source, unit to control degree of opening, unit to determine pad lowering rate and unit to correct signal. Said hydraulic source communicates via hydraulic control valve with aforesaid cylinder. Unit to control degree of opening generates signal to regulate degree of opening of aforesaid hydraulic control valve proceeding from preset pressure in hydraulic cylinder. Unit to correct signal corrects control signal in compliance with preset pressure in hydraulic cylinder and press pad lowering rate.

EFFECT: automatic control over load on pad.
