Abstract

The invention discloses a gas-liquid boosting pressure machine, which comprises a first pneumatic muscle, a first boosting cylinder, a second pneumatic muscle, a second boosting cylinder, a first three-position four-way valve, a second three-position four-way valve and a two-position four-way valve and a gas-liquid cylinder, wherein the first pneumatic muscle is connected with a piston rod of the first boosting cylinder; the second pneumatic muscle is connected with a piston rod of the second boosting cylinder; a gas source is communicated with a gas storage cavity of the gas liquid cylinder through the two-position four-way valve; the gas source is communicated with the first pneumatic muscle and the second pneumatic muscle through the two-position four-way and the first three-position four-way valve; and the first boosting cylinder and the second boosting cylinder are communicated with a liquid storage cavity of the gas-liquid cylinder through the second three-position four-way valve. According to the invention, the pneumatic muscles are used as drive sources, output tension force is converted into pressure of the liquid of the boosting cylinder to push the piston of the boosting cylinder to extrude and form a workpiece; and the output tension force of the pneumatic muscles is acted on the circular surface to replace the pressure acted on the air cylinder surface, so that the condition of the hydraulic pressure is realized.

Description

technical field [0001] The invention relates to a gas-liquid booster press, which belongs to the technical field of presses. Background technique [0002] The gas-liquid booster press is a common press, which usually uses compressed air as the power source, and uses the gas-liquid booster cylinder to increase the pressure of the compressed gas dozens of times and output the pressure; the advantages of this type of press are mainly It is high safety, small size, generally desktop, the pressure stroke of the gas-liquid booster is larger than that of ordinary punching machines, and can realize the function of maintaining pressure at the same time, the more important thing is that the power consumption of the gas-liquid booster is low, The advantage of the press is that the gas-hydraulic booster is maintenance-free, has no wearing parts, and has no pollution during use, so it is widely used in metal stretching and forming processes. [0003] The current gas-hydraulic booster pr...
