Abstract

The utility model relates to an oil-gas separation pressure boost cylinder. An oil hydraulic cylinder, a pneumatic cylinder and a pre-compression cylinder are combined, and compressed air led into the pre-compression cylinder is separated from hydraulic oil stored in the pre-compression cylinder to guarantee quality of the hydraulic oil and save cost for replacing the hydraulic oil. When compressed air enters the pre-compression cylinder, a pre-compression piston in the pre-compression cylinder is pushed to enable the pre-compression piston to push the hydraulic oil in an oil storage space of the pre-compression cylinder into an oil storage space of the oil hydraulic cylinder. An oil hydraulic piston of the oil hydraulic cylinder is forced by pressure of the hydraulic oil to drive an oil hydraulic piston rod to move towards a work piece. Finally, a hydraulic piston rod of the pneumatic cylinder is forced by air pressure to extend into the oil storage space of the pneumatic cylinder to improve contribution of the oil hydraulic piston rod of the pneumatic cylinder to the work piece to achieve pressure boost effect.
