[CN 201710566952.3] Testing System and Method for Main Hydraulic Cylinder of Radial Forging Machine
[CN 201710566952.3] Test System and Method for Main Hydraulic Cylinder of Radial Forging Machine Title: Test System and Method for Main Hydraulic Cylinder of Radial Forging Machine Application Number: CN 201710566952.3 Applicant: Shanghai Baosteel Industrial Technology Service Co., Ltd. Application Date: 2017-7-12 Patent Type: Invention Application The present invention discloses a test system and method for main hydraulic cylinder of radial forging machine, the system includes the main hydraulic cylinder body, piston rod in the cylinder body, front and rear end covers, charging valve, test frame, pilot hydraulic cylinder and hydraulic test mechanism. The main hydraulic cylinder body is set in the test frame, the front and rear end covers are set in the front and rear end faces of the test frame, the pilot hydraulic cylinder is set in the rear end cover and follows the piston rod through the charging valve. The test frame is provided with oil ports connecting the oil return chamber and return chamber of the return chamber of the main hydraulic cylinder; the hydraulic test mechanism is connected to the oil return cavity, return cavity and high-pressure cavity of the main hydraulic cylinder through a number of hydraulic components, as well as the rod cavity and rodless cavity of the pilot hydraulic cylinder; this method realizes the main hydraulic cylinder action and minimum start through the hydraulic test mechanism Pressure, internal leakage and pressure resistance test. The test system and method realize the offline test of the main hydraulic cylinder, save the manpower and material resources of maintenance, improve the efficiency of maintenance, avoid the repeated disassembly and assembly of the main hydraulic cylinder in the forging machine body, and ensure the quality of maintenance.
