Free forging hydraulic machine with high transmission efficiency and its operation method

摘要

The present disclosure relates to a high-efficiency transmission free forging hydraulic press and an operation method thereof. The high-efficiency transmission free forging hydraulic press comprises: a hydraulic cylinder, a hydraulic pump, and a pressurization energy storage apparatus. By providing two pressurization energy storage apparatuses between the hydraulic pump and the hydraulic cylinder of the high-efficiency transmission free forging hydraulic press, under the effect of a control system, the two pressurization energy storage apparatuses can alternately provide isobaric pressure oil or pressure oil having undergone pressurization to the hydraulic cylinder of the free forging hydraulic press, such that when the hydraulic pump operates in a status with a relatively low pressure, the hydraulic cylinder in the free forging hydraulic press can constantly obtain the isobaric pressure oil or the pressurization pressure oil, achieving the object of storage of surplus energy and high-efficiency transmission of the hydraulic press. The high-efficiency transmission free forging hydraulic press is reasonable in resource configuration, simple in provision structure, good in pressurization effect, and energy-saving and consumption-reducing.
