[CN 201910960842.4] Hydraulic energy storage system for hydraulic rolling thick plate shearing machine
[CN 201910960842.4] Title of Hydraulic Energy Storage System for Hydraulic Rolling Heavy Plate Shearer: Application Number of Hydraulic Energy Storage System for Hydraulic Rolling Heavy Plate Shearer: CN 201910960842.4 Applicant: Taiyuan University of Technology Application Date: 2019-10-11 Patent Type: Invention Application The present invention belongs to the technical field of metal plate shearer, and specifically relates to a hydraulic energy storage system for hydraulic rolling heavy plate shearer. It includes a first servo hydraulic cylinder and a second servo hydraulic cylinder whose ends of the piston rod are hinged above the frame and the upper tool rest through a push rod and a connecting rod respectively, and also includes a first rolling shear circuit and a second rolling shear circuit, The first energy storage unit, the second energy storage unit, the first hydraulic force booster circuit and the second hydraulic force booster circuit; the piston rods of the first servo hydraulic cylinder and the second servo hydraulic cylinder are respectively equipped with a first built-built-in displacement sensor and a second built-in displacement sensor. Through the use of the hydraulic force-increasing circuit, the shearing force of the hydraulic rolling wide plate shearing machine is improved, and the shearing thickness range is enlarged. The use of energy storage units plays a role in energy recovery, while speeding up the return speed and improving production efficiency. The double-pressure closed-loop cooperative control circuit ensures the control and adjustment of the shearing force of the hydraulic rolling wide-thick plate shearing machine.
