Abstract

The invention discloses a pneumatic-hydraulic pressure cylinder with multiple times of prepressing and pressure boosting and a working method thereof, comprising an air cylinder, an oil injection cylinder, a pressure cylinder and an oil cylinder, wherein the air cylinder is connected with the oil injection cylinder in series; the oil injection cylinder is connected with the oil cylinder in a prepressing way and is connected with oil cylinder unidirectional oil inlet in a prepressing way by a unidirectional oil inlet device respectively; the pressure cylinder is connected with the oil cylinder in a pressure boosting way; and the oil cylinder is suspended above a working face so as to carry out multiple times of prepressing and pressure boosting on the working face. According to the invention, the stamping process requirements of two times or more than two times of prepressing and pressure boosting can be completed by the pressure cylinder in a reciprocating return stroke.

Description

technical field [0001] The invention relates to the technical field of pressurized cylinders. Background technique [0002] The invention relates to a thrust element on stamping equipment widely used in one-time stamping. The working process of the gas-liquid pressurized cylinder is generally a three-step process of pre-compression, pressurization and return. In one-time stamping and forming equipment, it has the advantages of high efficiency, energy saving and environmental protection. At the same time, due to the structural limitations of the gas-liquid booster, the existing gas-liquid booster cylinders generally have the problem of only preloading, boosting, and return once each time, and cannot satisfy two or more consecutive preloading, boosting, and Press the stamping process requirements. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a gas-liquid pressurized cylin...
