HYDRAULIC PRESS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to metallurgy and cab be used at 650 MN hydraulic presses. Hydraulic press comprises bed frame composed of C-like plate cramps. Every cramp is composed by top and bottom semi-cramps rigidly interconnected to make the bed load-bearing strut. Plates are arranged between plates semi-cramps to close the joints there between. Cylindrical rolls are used for rigid attachment of semi-cramp with plates. Oval bores to receive spacers are made in abutting parts of semi-cramps and plates. Said elements are composed of split wedge rolls composed by two parts. Every plate in stack is arranged with shift of the axis of their oval bores relative to those of abutting parts of semi-cramps. One of split wedge roll parts abuts on plates by its cylindrical surface. Another part of said roll is coupled with abutting part of semi-cramp.EFFECT: higher reliability of joints between semi-cramps.3 dwg
