CASING OF HIGH-CAPACITY HYDRAULIC PRESS OPERATING CYLINDER Russian patent published in 2009 - IPC B30B15/04 B30B1/32 F16J10/02 

FIELD: mechanics.

SUBSTANCE: casing of the high-capacity hydraulic press operating cylinder used at fluid pressures of up to 32 MPa comprises the walls and bottom welded together. The wall features thickness h_w and is furnished with the support flange coupled with the former by a shaped moulding. The bottom features thickness h_b=2 h_w and is coupled with the wall inner surface by the moulding arranged along the radius. There is a hole to feed operating fluid into the cylinder arranged at the bottom centre. The said moulding is buried into the bottom for h_br=(0.3 to 0.4) h_w to form a ledge on the bottom inner face with its size equal to that of the moulding h_br. The moulding radius equals (0.7 to 0.8) h_w.

EFFECT: higher reliability with no increase in weight and sizes.
