[CN 201810555382.2] A New Type of Main Cylinder Structure of Winding Hydraulic Press
[CN 201810555382.2] Main cylinder structure of a new type of winding hydraulic press Title: Main cylinder structure of a new type of winding hydraulic press Application number: CN 201810555382.2 Applicant: Fujian Haiyuan Automation Machinery Co., Ltd. Application date: 2018-6-1 Patent type: Invention application The present invention relates to a main cylinder structure of a new type of winding hydraulic press, it includes a transition plate, a charging valve, a main oil cylinder, a main piston, a charging valve control oil circuit that controls the opening and closing of the charging valve, and a hydraulic control oil circuit that controls the slow downward movement of the main piston; the transition plate is opened for The hydraulic oil channel connecting the oil cavity and the valve port of the charging valve, the main oil cylinder is fixed on the lower bottom surface of the transition plate, and the main piston is arranged in the main oil cylinder barrel, the main piston rod of the main piston passes through the main oil cylinder and fixes a force-bearing component, and the force-bearing component acts on the compression mold object; the charging valve is fixed on the lower bottom surface of the transition plate and the charging valve The valve core is located in the main oil cylinder. The main oil cylinder structure of a novel winding hydraulic press simplifies the structure, reduces oil leakage, improves the guiding accuracy of the main piston, saves the cloth stroke, and improves the pressing efficiency.
