Energy-saving type low-vibration fast-response mixed control servo hydraulic machine hydraulic system

Abstract

The invention provides an energy-saving type low-vibration fast-response mixed control servo hydraulic machine hydraulic system which comprises a single-action working feeding cylinder, a double-action quick feeding cylinder, a working table, a working feeding hydraulic circuit, a quick feeding hydraulic circuit, a controller and a displacement sensor. Piston rods of the single-action working feeding cylinder and the double-action quick feeding cylinder are connected with the working table, the working feeding hydraulic circuit and the quick feeding hydraulic circuit control the single-actionworking feeding cylinder and the double-action quick feeding cylinder to do reciprocating motion, the input end of the controller is connected with the displacement sensor, the output end of the controller is connected with the working feeding hydraulic circuit and the quick feeding hydraulic circuit, and the displacement sensor is installed on the working table. By means of the energy-saving typelow-vibration fast-response mixed control servo hydraulic machine hydraulic system, the response speed of the hydraulic system can be greatly improved, the production efficiency is improved, the working table vibration amplitude is reduced in the forging process, and the better energy saving performance is achieved.

Description

technical field [0001] The invention belongs to the technical field of forging equipment hydraulic systems, and in particular relates to an energy-saving low-vibration and fast-response hybrid control servo hydraulic machine hydraulic system. Background technique [0002] As the shape of parts becomes more and more complex and the requirements for machining accuracy increase, the performance of forging processing equipment for parts is also getting higher and higher. For the hydraulic press commonly used in the forging field, its performance has an important impact on the precision of parts. At present, the hydraulic system of domestic forging equipment has a slow response speed and large equipment vibration, and there is a big gap between the forging capacity and the international advanced technology. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving low-vibration and fast-response hybrid control...
