CONNECTION OF HYDRAULIC PRESS TOP CROSSBAR WITH WORKING CYLINDER Russian patent published in 2015 - IPC B30B15/00 F16J10/02

Abstract RU 2552800 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production of presses and can be used in development of new hydraulic presses and updating of existing presses. At connection of hydraulic press top crossbar with its working cylinder the locating ledges of the latter are jointed with grooves at top crossbar. Working cylinder support flange is jointed with top crossbar bottom surface by fitting the suds via pressure ring. Working cylinder locating ledge, the closest to support flange, is jointed with top crossbar groove with interference fit. The other locating ledges are connected with crossbar grooves with clearance. Said clearance equals or exceeds the magnitude of elastic strain at loading of working cylinder.

EFFECT: decreased wear of mating surfaces of working cylinder flange and top crossbar.
