A multi-point active load biasing device between a main oil cylinder and a sliding block of a hydraulic machine

Abstract

The present application relates to the technical fields of forging hydraulic press, and discloses a kind of multi-point active eccentric load suppression device between hydraulic press main oil cylinder and sliding block, including sliding block body, cross, sliding block guide, main oil cylinder plunger rod and auxiliary oil cylinder plunger rod, further including main oil cylinder connecting mechanism, main oil cylinder connecting device is installed in outer sleeve, outer sleeve is installed at the intersection of cross and is connected with the center of sliding block body using ball hinge, allow sliding block body to have angular swing, reduce the eccentric load force that main oil cylinder plunger rod receives, variable stiffness support unit is arranged in the side wall of cross and is located in the upper end of sliding block body, for real-time monitoring the pressure that sliding block body is passed to cross and sliding block guide on.The multi-point active eccentric load suppression device between hydraulic press main oil cylinder and sliding block, can actively, quickly regulate and control sliding block stress distribution, can also change passive bearing to active regulation from eccentric load suppression, reduce damage to main oil cylinder seal from source.
