Abstract

The invention provides a single-acting pneumatic hydraulic intensifier. The single-acting pneumatic hydraulic intensifier comprises an oil cylinder, a pressure cylinder and a pneumatic hydraulic cylinder, all of which are connected in sequence; the oil cylinder is provided with an upper cover, a lower cover and a piston; a pre-pressure cavity is formed between the piston and the upper cover, while an oil storage cavity is formed between the piston and the lower cover; the pressure cylinder is provided with an upper pressurization cover, a lower pressurization cover and a middle pressurization cover; a pressurization piston is arranged between the upper pressurization cover and the middle pressurization cover; a pressurization cavity is formed between the pressurization piston and the upper pressurization cover, while a return cavity is formed between the pressurization piston and the middle pressurization cover; a pressurization oil cavity is formed between the lower pressurization cover; a pressurization rod connected to the pressurization piston extends into the pressurization oil cavity; the pneumatic hydraulic cylinder interior is divided by a working piston into an oil cavity and a gas cavity; the pressurization oil cavity is connected with the oil storage cavity and the oil cavity, respectively. By means of such a solution, fast movement and pressurization are realized by using the pneumatic technology, and high pressure output is realized by means of hydraulic control, and therefore, the gas consumption is low, and so is the energy consumption; the single-acting pneumatic hydraulic intensifier is compact in structure, high in reliability and low in cost, and realizes complete gas-liquid isolation; besides, the working push rod is fast, steady and controllable in motion.

Description

technical field [0001] The invention belongs to the field of booster cylinders, in particular to a single-acting gas-liquid booster. Background technique [0002] In the prior art, the gas-hydraulic booster cylinder is widely used in machining, packaging and other industries. The gas-hydraulic booster cylinder combines the oil pressure cylinder with the supercharger, and utilizes the ratio of the stressed area of ​​the supercharger and Pascal energy balance principle. However, the existing gas-liquid pressurized cylinders have problems such as complex structure, poor gas-liquid isolation effect, easy collision with the cylinder when the push rod returns, large impact, high noise, and low service life, especially the large gas consumption, high energy consumption, and high cost of use. high. Contents of the invention [0003] In view of this, the present invention aims to propose a single-acting gas-liquid supercharger to solve the problem of large gas consumption of the ...
