HYDRAULIC PRESS FOR BUSHINGS PRESSING-OUT OR PRESSING-IN Russian patent published in 2020 - IPC B30B1/32 B30B15/04 B23P19/27 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and may be used for bushings pressing-out and pressing-in, for example, in cylinder head of internal combustion engine. Press comprises frame 1, on which table 24 is located with rotary platform 26. Upper part of frame 1 is formed by two vertical posts 4 and 5, in upper part of which horizontal linear guide 6 is fixed. Movement mechanism 8, comprising horseshoe-shaped housing, moves up and down along vertical guides 14 and to the left and to the right along horizontal guide 6 with support on bearings fixed in spherical supports. In lower part of movement mechanism 8 stopper 23 is installed with central hole coaxial to axis of rod 20 of hydraulic cylinder 19 located in upper part of movement mechanism 8. In lower part of frame 1 in vertical posts there fixed is the second horizontal linear guide 7, which provides movement of movement mechanism 8 to the left and to the right with support on bearings fixed in spherical supports.

EFFECT: result is prevention of bushing distortion and jamming during their pressing-out and pressing.
