The invention relates to a hydraulic control system with a double-feedback active proportional servo cartridge valve for a CNC (Computer Numerical Control) bending machine, in particular to hydraulic control system equipment with the double-feedback active proportional servo cartridge valve for the CNC bending machine, wherein the hydraulic control system is synchronized actively and has adjustable speed servo. The hydraulic control system consists of two main cylinder control valve banks, an oil inlet control valve bank and a workbench compensating oil cylinder, wherein the two main cylindercontrol valve banks are arranged separately; two double-active servo cartridge valve units, a safety control unit and a pressure regulating unit are arranged in each valve bank; the two main cylindercontrol valve banks are used for driving corresponding main cylinders respectively to ensure the synchronous position accuracy of each main cylinder; and the oil inlet control valve bank is used for controlling the inlet and outlet of oil and the proportional regulation of the system pressure and supplying pilot control oil to the double-active servo cartridge valve. The hydraulic control system has the advantages of simple structure, accuracy and simplicity and convenience for operation control due to the adoption of the cartridge valve, stability and reliability for work, no leakage, high efficiency, reduced energy consumption, reduced equipment manufacturing cost and high integration degree, and is widely applied to the hydraulic control equipment of the CNC bending machine.
Description
Technical field: [0001] The invention relates to a hydraulic control system for a CNC bending machine with a dual feedback active proportional servo cartridge valve, in particular to a hydraulic control system equipment for a CNC bending machine with active synchronization and adjustable speed servo with a dual feedback active proportional servo cartridge valve . Background technique: [0002] At present, CNC bending machines are mainly used for sheet metal processing, which can automatically calculate the mechanical position according to the angle, reduce the difficulty of operation, and improve work efficiency. The spool valve hydraulic control system equipment developed in the 1950s is mainly used in the CNC bending machine system. The performance parameters of the spool valve hydraulic control system are low. The device produces a large eccentric load moment, which cannot guarantee the displacement accuracy of the oil cylinder, and may cause deformation of the main mach...
